That's what I get for not looking up the card first. D'oh. I always do that with AMD hardware it seems. Sorry guy. Yeah, if it's non-reference and loud as poo poo then it's either faulty fans (they get reeeally screechy at high RPMs as they fail, sometimes) or just plain something wrong with the card. That's a lot of heat to exhaust but aftermarket cooling should do a better, not a worse job than reference blowers - and quieter, certainly. RMA that sucker.

Apparently that card kind of sucks (a review near the top states it pretty well - "cons: xfx"). 208 reviews, and three eggs, with most complaints relating to getting dead on arrival or dying units. Fair number about the fans being noisy, too...

If I could just return it quickly and pay the difference for a Palit GTX770 or something I would do it. It would even match my case much better. Unfortunately I bought it from a dutch website and I don't speak any dutch so i can't even find information about returns on the website. I'm exchanging emails with them, but don't know if I can do anything. They asked me for a recording of the noise.I uploaded it here: http://saginata.elektroda.eu/7970.mp3

It was recorded a foot from the side of a closed case. At first the fan is set to auto and running at about 80% while keeping the card between 80-85 degrees C. Then it's manually set to 20%, then 50% and then back to 80%. Does this sound normal? It's way louder than any of my case fans or the CPU fan. Could a custom cooler do a much better job or is watercooling my only option if they don't take it back?

I am not an AMD guy and I am especially not an XFX guy, but there's no way in hell a card runs that noisy and still hits mid 80sºC without SOMETHING being wrong. Airflow in the case is one possibility, not to be discounted totally, but that level of poor heat exchange is pretty absurd for an after-market, pricier cooling solution.

I don't know why they'd ask you to send a recording in, that tells them nothing. Is it even properly normalized so that the level of noise comes across? That's not a cool thing to ask of a customer who has an issue. Are there no consumer protections that apply to protect you from having to just eat a faulty product or look at a pricy after-market cooling solution? That sounds absurd.

That is really unfortunate. Personally right now I have a Sapphire 7870 GHZ with the dual fan thingy and it only gets to mid 50s-low 60s running stuff like Metro Last Light or even Heaven and runs super quiet. I'm impressed.

Likewise, I run a Sapphire 7970 GE Vapor X and it's inaudible at idle (about 30c) and only slightly noticeable at full load (mid 50's or 60 even). When I crank the fans to 100% that I can hear it from another room.

I have the the "Dual X" OC (lower clock) version and it's pretty much the same deal. Even OC'ed it tops out at 65 c and is not loud at all.

The disruptive powers of excessive national fecundity may have played a greater part in bursting the bonds of convention than either the power of ideas or the errors of autocracy.
I switched from my previous XFX HD5870 precisely because it was loving noisy. At any decent graphical load the fan would go up to 50% which was loud enough to be annoying when playing with a decent volume, and anything serious went to 70-80% fan speed and screamed through Bose noise cancelling headphones. Even when idle, it was often loud enough to be heard. Granted, it was using the reference fan, but it pretty much soured me to XFX.

On the other hand, the two MSI 7850 TwinFrozrs are comfortably quiet. Something like Bioshock Infinite will be enough to get the fans to a level where I can hear them, but it's still way better than the leafblower... And even when manually setting both fans to 100%, it's still quieter than the XFX.

On a different subject, does anyone know of any issues with AMD, DisplayPort and turning off monitors? I sometimes get issues where if I turn off my DisplayPort connected monitor and leave it off for a fair amount of time but leave the computer running. When I come back and turn the monitor back on, the monitor doesn't detect any signal. Sometimes I can get it back by cycling the monitor power a few times, but I've also had one or two cases where the drivers freak out, cause a reboot and then Windows is in VGA mode with the device manager saying the card was disable because it was causing issues.

Quick edit: just realised that the monitor was still using the generic PnP driver. Had it update to get the Dell U3011 driver, I suppose time will tell if makes a difference.

I've owned a few dual-fan XFX cards and while they've never really been as quiet as I'd like, I haven't experienced any issues with overheating or unbearable noise. Something's probably wrong with the TIM seating on the GPU core or there's zero case airflow, since a 7870 in particular should perform better than that.

The reference fan on my 6970 was pretty loud before I replaced it with aftermarket cooling, but most AMD reference blowers are loud in general.

If the monitor driver doesn't help, it might be related to the Zero Core power state. Like maybe it's not detecting when you turn the the display back on because the IO is totally off? I'd suggest using only windows power saving rather than complete power off.

(If you want manual control of turning off your screen, there's a great little utility called nircmd that does a whole bunch of useful little things, including power saving the monitor. It's easy to put a shortcut in quicklaunch or someplace to just instantly sleep the monitor whenever you leave the pc.)

MSI 7850 TwinFrozrs
My previous video card was an (nvidia) MSI twinfrozr. Decent cooling and nicely quiet, but they use some cheapass fans. One of the fans was on the way out with grinding noises after just a year of use. I hacked in a replacement myself because I really didn't want to be without a computer for a week+ of RMA. Then just before I got my new card the second fan started grinding, so if I want to use the thing again I'm probably going to need to pull off both fans and replace them with slim 80s that can do PWM. Ugh.

I saw lots of forum posts about dead twinfrozr fans when I googled about it.

The things about bearings in cheapass fans is that they're probably sealed, assuming they're ball. If it's sleaved or unsealed ball I've replaced these in the past but only on cards that were out of warranty. I'm sorry you decided to fix/replace the fan on something that was still in warranty, cause it ain't now.

That's the difference between a good company and a bad one. EVGA not only allows you to swap coolers, but they even offered suggestions on volt mod limits. (1.3v if anyone wants to hard mod their GK104, but of course THATs the type of thing that does void your warranty)

I don't really have a problem with the temperatures. The back of the PC is hot, so it doesn't seem like a problem with heat transfer between the cooler and the GPU. Airflow shouldn't be an issue. I have two intake 140 fans in the front and a fan between the card and the hard drive cages. Cables are managed: http://pcpartpicker.com/b/DrD . The only way to get a feel for the level of noise is to compare it to the sound of mouseclicks in the recording. I will probably get a SPL meter soon. It's an useful thing to have.

It seems that there's nothing wrong with the card except it being a lovely card. I have no idea how I missed this when doing my research. I don't think I can return it now, when it was just my stupid choice. The specs for the card don't specify the noise level. I don't really mind getting a custom cooler that much. From what I read in reviews it's an improvement over non-lovely coolers too. I'm thinking of getting this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16835186068 . Even if I return this XFX card, that means I have to spend a week or two without a computer. The integrated GPU on my i5 won't be able to handle my main monitor.

I'm not. The problem with warranty RMAs on a stupid little problem like that is, between the cost to ship the part and the value of my computer being a doorstop for however long it takes to get a replacement, warranty service easily had negative worth compared to fixing it myself. I didn't have a space pcie card at the time, I had just given away an old card to a friend. And MSI seems to be near-impossible to get cross shipping from.

Though if I had known then what I know now, I would have gone directly to a solution that ditched both stock fans. (Also, warranty violations, pshaw. If you're patient and meticulous, you can solve that just by being better at reassembling the thing than the guy who put it together in the first place.)

On the nVidia side of things, EVGA straight up doesn't give a poo poo so long as you don't voltmod the BIOS and can reassemble the stock shroud to factory condition (or better, if you want to use fancy TIM they're not going to gripe :v:) - that's for RMA, Step Up, you name it.

On the other hand, I would think the hardest part about attempting to defraud a company and pretend you didn't violate the warranty would be those stickers they put on that are designed to break easily if you try to pull them off and of course are obviously torn through by a screwdriver...

Now my ASUS 660Ti with a nice non-reference cooler is running hotter in my better ventilated main rig than my EVGA 660Ti with the reference blower cooler in my less ventilated HDTV rig. I'm talking by about 5 degrees Celius hotter despite having a better cooler and better ventilation. The card isn't overheating yet but when I first got it under load the temps would peak around 70C now they are peaking at 80C. I just blew what little dust was in it out so what's the deal?

Factory Factory
Mar 19, 2010

This is what
Arcane Velocity was like.
Blowers have a lower performance ceiling, but they excel at operating in poor airflow. Meanwhile, dual-fan coolers need air exchange not just in general, but specifically taking the hot exhaust they spew into the area around themselves and moving that hot air elsewhere. If your side panel has a vent or (better) a fan mount, getting some air moving through that will affect the custom-cooled 660 Ti's temperatures greatly.

n.b. 80 C is a perfectly fine temperature for a GPU and there's no need to change things.

Agreed
Dec 30, 2003

The price of meat has just gone up, and your old lady has just gone down

It's possible, on an outside chance, that the TIM has bubbled or otherwise isn't making sufficient contact. Might be a warranty-voiding fix but if you were to reapply it that could fix it.

Otherwise, if it's the DirectCUII model (or the mini variant), anything that exhausts heat inside the case can be upset if it doesn't get air pretty precisely how it wants it. If there's some lack of airflow in that particular spot due to air routing convectively around it because it's putting off hot air and there's no side fan pushing air right to it, it is possible that it's just not getting the kind of airflow it needs, even if your case is in general very well ventilated.

Blowers do well in any kind of case, and require much less specific kinds of airflow to perform well. A 5ºC difference in that setting might just mean that there's an airflow issue to the card; or, the 10ºC difference between its original performance and current performance might mean you've got something non-ideal going on under all that heatsink. It happens, TIM can desiccate or a bubble can emerge, especially due to transport of the card, if there's not perfect mounting - the PCB flexes a little and all of a sudden the interface between the heat sink and the GPU changes, probably not for the better.

Some ideas, anyway. Good luck.

The case I have it in is a Corsair Carbide 400R and the side panel has a vent and two fan mounts but I haven't mounted a fan there because I have a tall custom cooler on my CPU so I don't know if I could fit a fan there now or not. It only has the two front intake fans and one rear exhauast fan but I replaced all three with fans that move more air and don't have the stupid LEDs. I might try re-applying the thermal paste but I've never done that to a GPU before I've only done that to CPUs. And yes its the ASUS DirectCUII model with the dual fans which is why I'm concerned having a 80 Celsius load temp.

The above suggestion to run it with the side of the case off is a better starting point that yanking the cooler off on suspicion of dried/problematic TIM. Figure ouf it you have an airflow issue first. I know that on my 650D, the fan mount positions have no real overlap as to where the cooler is - in fact, the ideal 200mm fan mount position is RIGHT where it needs to be to push air at the graphics card(s). I know of (and use) one excellent slim 120mm-mountable fan, though it is an overall 140mmX140mm cage - the Prolimatech PRO-USV14; depending on how much clearance and where the fan mounts are located, it's possible that you could stick one of those blowing right at the GPU, if it turns out that taking the side off helps the issue (indicates airflow problems), and at 98CFM and only 15mm thick it'd definitely do the trick in terms of getting some air moving, provided that it fits.

If that's a no-go due to heat sink clearance, possibly see if the lower mount doesn't compromise your heat sink; there are plenty of good options in the 120mmX120mm form factor, of course,

Hey guys,

A friend of mine is having trouble with his 6950, more specifically this one: http://us.msi.com/product/vga/R6950-Twin-Frozr-III-Power-Edition-OC.html A few months ago he attempted to unlock the shaders on it using a random guide he found on the internet. According to GPU-Z he was successful but recently has been having crazy high temperatures. Using Hwininfo64 the GPU shader core was getting to 102 degrees Celsius and the other 3 cores were around 90 with the GPU fans at 100%. I cleaned out as much dust as I could (it was pretty bad) without being able to take off the shroud (we didn't have a small enough screw driver), I was able to get most of it out after a lot of effort. After that I found that MSI had released an unlocked bios themselves for the 6950. So I downloaded that and successfully reflashed the bios. Loaded up Hwininfo64 and Guild Wars 2 and played for about 10 minutes. Temps were OK for a minute or two and the fans weren't very loud. But shortly after the fans got really loud again and after about 10 minutes I alt-tabbed out to see that the shader core was once again up to 97 degrees Celsius.

I'm pretty sure that this isn't supposed to be happening and I thought about flashing the original unmodified bios on but my friend had recently reinstalled win 7 64 and didn't save the original bios. Is his card completely hosed or is there something else I can do to help him out?

Unless you've got a super beefy multi-fan setup that fits, keeping the side off your case is almost always cooler than having it on. Makes your PC more vulnerable to errant dust, of course.

Because this is mainly to make dark souls work better you could try increasing the internal resolution above 1920x1080 in dsfix (or decreasing it if gpu-z doesn't show your card going into low power states and this is some legitimate dark souls is too much for your gpu issue)

That's not normal at all. The high temperatures probably indicate that the cooler needs to be re-seated on the card, which you can do with a jeweler's screwdriver and some patience. The BIOS you used could still be pushing higher voltages to the card or something though so you really should have made a backup..

What does the shader count read as in GPU-Z? If it's 1408 then the card is still locked. If it's 1536 then it's unlocked, however the BIOS could be causing issues if it's not specifically tailored to that card. Most unlocked 6950 BIOS' were only for reference, early release cards (all later cards were locked-down), whereas that MSI one is non-reference so it may not be matched to the card.

Does that card have a switch by the Crossfire connector? Most of the early cards had a dual-BIOS switch by the connector that selected between the running & backup BIOS. Turn the PC off before switching it if it's present since it may have the stock BIOS stored already. The later cards tended to remove the connector or turned it into a fan-speed toggle though (looks like your card does that).


Your other option is to check here for a stock BIOS and re-flash it (you should probably do this anyways to eliminate a possible source of problems) :

Pretty much except the power target is more restricted since it's not concerned with temperatures. As long as you have good case airflow you can safely max out your power target right now and it's not even going to overclock the card, just make it stay at the highest boost clock more frequently under high loads (Arguably more important than overclocking anyways).

The smoothness is noticeable immediately, just watching your mouse pointer wiggle around on your desktop. Keep in mind that unless you can hit 60+ FPS consistently in games you won't actually see it. I don't think it has much effect on my gaming performance compared to 60 FPS, but it sure does look nicer. I've been pretty happy with the 2D image quality, but this is by far the nicest monitor I've ever had. I can't make a comparison to a Dell ultrasharp or anything.

I'm curious to hear if anyone's gone between an Ultrasharp and the Asus 144. I really like my U23's and I'm not sure if be willing to trade the IPS for a TN panel if there's a notable difference in the viewing experience.

Then again, I may be too much of a stunned arse to notice a difference anyway. :froggonk:

Pretty much except the power target is more restricted since it's not concerned with temperatures. As long as you have good case airflow you can safely max out your power target right now and it's not even going to overclock the card, just make it stay at the highest boost clock more frequently under high loads (Arguably more important than overclocking anyways).

Yeah, the real secret in short form is that these cards will happily overclock themselves to within a tiny percentage's performance difference if you just use the temperature and power targets maxed and keep them cooler than, what, 94ºC for 2.0, and 70ºC for 1.0 (big deal, you lose 13MHz). The overclocking manually done on top of that is a considerable amount of effort for way less return, especially with a card like the 780 ACX which already boosts into 1100MHz because of a much more aggressively tuned BIOS. I have mine, which is a decent but not remarkable sample, at 1175MHz out of principle of getting every last drop of performance, but for most folks and most usage scenarios, nVidia (and to an extent ATI as well, I hope they jump on the thermal target bandwagon) has made it dead simple for vendors to push great cards that perform extraordinarily well right out the gate.

With the 680 and double for the 670, you do have to be more precise though since you have a severe TDP limit if you want to get the benefit of full turbo; as you well know, have to make efforts to to balance GPU/SMXs with VRAM or you'll end up getting memory bandwidth bottlenecked with a uselessly high core clock. One solution of course is to just go in and up the power limit if you don't mind voiding the warranty, any after-market cooling should handle that and the chip shouldn't complain much.

Reminder to anyone just kinda watching along on the nVidia discussions, the GTX 770 is basically an overclocked (or, rather, higher clocked, since this has been an easy process node and yields are apparently great!) GK104 chip with factory 7GHz GDDR5 VRAM modules and 40W higher stock TDP, which totally solves the bandwidth limitation of the 680. Their max overclock on the core tends to be the same, but it's a lot easier to get on the 770 because you can just completely leave the VRAM alone (plus the coolers this generation are awesome, I think it's hilarious that EVGA seems to have repurposed some Titan/780 coolers for use on the 770).

My speculation is that the Titan cooler, being the most effective vapor chamber GPU blower to date and made out of a lot of metal and not a lot of plastic, is actually more expensive to produce than EVGA's aftermarket ACX cooler. You can get the 780 SC for the same price and they save money on it, dollars to donuts, and everybody wins because it happens to be a very well designed cooler for the 780. Shame it doesn't scale as well to the 770 or 760, but they win the top end this go around :unsmith:

Hey guys,

A friend of mine is having trouble with his 6950, more specifically this one: http://us.msi.com/product/vga/R6950-Twin-Frozr-III-Power-Edition-OC.html A few months ago he attempted to unlock the shaders on it using a random guide he found on the internet. According to GPU-Z he was successful but recently has been having crazy high temperatures. Using Hwininfo64 the GPU shader core was getting to 102 degrees Celsius and the other 3 cores were around 90 with the GPU fans at 100%. I cleaned out as much dust as I could (it was pretty bad) without being able to take off the shroud (we didn't have a small enough screw driver), I was able to get most of it out after a lot of effort. After that I found that MSI had released an unlocked bios themselves for the 6950. So I downloaded that and successfully reflashed the bios. Loaded up Hwininfo64 and Guild Wars 2 and played for about 10 minutes. Temps were OK for a minute or two and the fans weren't very loud. But shortly after the fans got really loud again and after about 10 minutes I alt-tabbed out to see that the shader core was once again up to 97 degrees Celsius.

I'm pretty sure that this isn't supposed to be happening and I thought about flashing the original unmodified bios on but my friend had recently reinstalled win 7 64 and didn't save the original bios. Is his card completely hosed or is there something else I can do to help him out?

http://www.vortez.net/articles_pages/msi_r6950_twin_froz_iii_power_edition_unlocking,1.html

This is the specific page I used to help me when I unlocked my 6950 MSI Twin Frozr III. I did it basically the same day I got the card, and it still runs fine to this day. Looks like the download links still work on that page even.

Doesn't the card have a dual BIOS switch to unfuck it regardless? I haven't actually stared at for a while, so I don't remember exactly.

While it's a good thing to try now, it was really worthwhile at the time, as an unlocked 6950 for a long, long time basically met some kind of insane price/performance point. I have a feeling this is when people thought the 560 Ti was a good deal, when it flat out wasn't compared, plus with the 6950 you had 2GiB VRAM. Literally getting the next model up for free will do that, though.
