^^^ I was just about to say to take a look at his rap sheet and ignore him, but it seems that a mod's already taken care of it.  veedubfreak posted:For those of you having the black screen issue, have you tried putting a 290x bios on the card? All my cards have an unlocked bios from day1 and I have never had this issue. Perhaps the 290x bios gives more power to the memory along with the gpu. Yeah, I'm running the Asus 290X bios (my card was among the lucky ones that unlocked). I tried increasing the power limit by 10%, which seemed to do the trick in Borderlands 2 (for now), but Unigine Heaven produced black screens. Now at 25%, Unigine has run 3 passes without an issue. I won't know for sure for a day or two, but things seem to be looking up. Thanks for the suggestion, Stanley! Straker posted:Any way to check without taking off the cooler? I remember using that one utility to check if my 290s were unlockable but forget its name or if it gave any hints as to RAM manufacturer. I think I posted in this thread but I was getting some pretty loving infuriating bluescreens, driver problems etc. myself, but those have all cleared up for whatever reason. I'd reboot half a dozen times and get things working with new drivers, then BSOD for a seemingly unrelated (but obviously actually related) reason. I ended up taking out my ATI TV tuner and making one or two other small hardware changes that I can't remember, and still had the BSODs, and then they magically went away. Might have also been nudged along by a flaky hard drive that I think has caused just a small handful of BSODs over the past month or two. That'll have everything you need. Just run "MemoryInfo.exe" within the "Hawaiinfo12" folder. Ghostpilot fucked around with this message at 23:16 on Feb 3, 2014 |

No worries, black screens were the bane of my existence for a while. Lots of tinkering and it came down to memory timing issues. Since I'm not skilled enough to hack up a bios to change memory timings (nor do I even know what timings would be good) I figured more power usually works  .

Looks like my first GPU has Elpida RAM, and can't tell for sure with that utility but probably also the second, since they're both HIS cards ordered at the same time and neither unlocked. No black screen issues though, and like I said, they've been good lately. edit: also, in just what way is this RAM supposed to be flaky? because mine ran for days at 1500MHz no problem.

Straker posted:Is there any particular reason for saying this? Just curious - I know I mentioned in at least one thread but I mined a couple gimmicky altcoins for fun for just a few days and to get the best performance out of 290s you generally have to oc the VRAM and sometimes even underclock the GPU. You can get pretty crazy overclocks on the RAM without any special cooling, especially if you don't have to worry about dealing with heat from an overvolted OCed GPU, and mining makes it super obvious once you start getting errors, more than just a couple flashing pixels does at least. Unless you're just saying not to bother because it's generally not very helpful, in which case yeah of course, nobody overclocks their system RAM any more either. If you'd like a really detailed response and he's in the mood for it, ask Professor Science about the stability of GDDR5 and overclocking. The basic gist is that while you can post some (visually, pretty remarkably) high numbers, you start running into errors very quickly into the adventures of trying to run out of spec the GDDR5 and the memory controller and, consequently, the whole memory subsystem (as such... not really analogous to a CPU's memory subsystem but not germane to the topic). You can see a pretty good breakdown of some older behavior-as-intended with Fermi SMs vs. VLIW SIMD cards (5000-series from AMD) in this paper - http://www.ece.lsu.edu/lpeng/papers/iiswc11.pdf - no longer applicable, since SMX is weird and we're one update to VLIW and two iterations of the newer GCN u-arch (which went from VLIW SIMD to RISC SIMD) away from what's being discussed in the paper there. The main thing is just that it's all a very delicate process, that GDDR5 without error correction is difficult to trust when run outside of its intended parameters (and can kick up issues even at nominal speeds, as we're seeing with the Elpida memory sucking monumental amounts of rear end). Hopefully VRAM overclocking issues that aren't showstopper system crash issues won't ever manifest as anything other than some mistakes in geometry or textures or whatever, but a supposed-stable VRAM overclock is a good place to start looking if you notice instability that doesn't follow a consistent pattern in active use but artifacts or crashes out inexplicably, even after hours of stability. It's a totally different matter talking about stability under GPGPU conditions where math errors manifest more readily - a Memtest86-like program for GDDR5 would be pretty damned revealing even when pointed at overclocks that we as gamers probably consider stable, throwing around bit errors left and right.

I've seen a few graphic cards "the mod" to put a CPU watercooler on the card and some talk about Kraken X10, but does anyone have any experience setting up the Kraken X10it up? I just got mine in the mail and a few reviews/forum posts suggestion putting some copper VRAM heatsinks and was wondering if anyone found any that would fit well. I'm sort of in a bind as I have a 760 and I'm thinking this is a lot of work for this card and thinking maybe I should upgrade to 780 or 290X if I want to mess with this. Would water cooling a 760 be overkill if I'm not hitting serious heat problems?

I put together a The Mod card using a non-Kraken adapter bracket. It would be pretty overkill to The Mod a 760, yeah. The Mod can handle hugely more power dissipation than a GeForce 760 can put out, which is handled fine and at low volumes by air cooling. I didn't use any copper on my VRAM or whatnot and it's working fine. The VRAM just doesn't get that hot; the rear fan on the bracket does just fine moving air and cooling the chips. That said, I'm not overvolting the VRAM any or overclocking it particularly hard; I'm focusing on the GPU itself.

How does Vsync work with odd refresh rates? I remember a long time ago I used a monitor with an 85 Hz refresh rate. When I wasn't getting 85FPS how was it syncing "42.5" frames? Did it throw out alternate frames or would there be tearing from exactly half the screen updating? It doesn't really matter now, it's just something I was wondering about and couldn't find the answer by searching.

It doesn't really matter now, it's just something I was wondering about and couldn't find the answer by searching. As I've recently discovered, some programs won't force triple buffering by default with VSync enabled and so will immediately downshift to double buffering (42.5fps on your monitor) when the framerate dips below maximum. You can solve this by downloading a program like D3DOverrider to force triple buffering or using NVidia Inspector / Radeon Pro to set the framerate limit with Adaptive VSync enabled.

Thinking about it some more, the length of a second probably isn't what matters. It's probably just doubling the length of time a frame is displayed.

A question for people who use a dedicated PhysX card: how hot does that card get, and what kind of fan does your main GPU use? The fan on my 560 Ti 448 is starting to become louder than I really like when under load, and I've been looking to get a new GPU anyway (the 770 has been going up in price though, which is annoying), but I'm not sure what I'm going to do with the old card. At 40% fan speed it's still fine, so if being used as a PhysX card won't make it go over, say, 60 C, I can probably get away with just leaving the fan on minimum. I imagine it will be affected by the type of fan on the other GPU, since a non-blower type will be dissipating heat into the case rather than out of it, so that's another consideration.

Mine's an EVGA 650 Ti, it doesn't get very hot at all (maybe 45-55ºC under heavy PhysX load, and right under a 780Ti with an internal exhaust cooler) and uses a single 90mm fan to cool it. It exhaust internally. I can make it get hotter with FluidMark, but games don't do that. Should probably note that I have a really weird airflow setup designed to cool the poo poo out of the PCI-e slots and bottom half of the mobo generally.

Rumors/leaks about the first nVidia Maxwell cards are starting to firm up. The first Maxwells will be be built on the existing 28nm manufacturing process and will be released as the GTX 750 and GTX 750 Ti to slot in below the GTX 760 in the product lineup, and as you might expect will be a few percent faster than their GTX 650 and GTX 650 Ti counterparts. nVidia's plan seems to be to test the Maxwell architecture on 28nm for a while before doing a process change to 20nm for the 800 series.

Diablo 3 expansion?  EoRaptor posted:http://promotions.newegg.com/premier/trial/index.html Mmm, this is a little worrying, as most of them are things Newegg has traditionally provided anyway.

That's disappointing news about the Maxwell cards getting bumped back. I was looking for an excuse to upgrade from my 3GB 580 SLI setup but I think a 780Ti would be at most a sidegrade, and I'd be better served using that money for literally anything else.
