There's a ton of completely ordinary applications that will use AVX these days, so you won't actually get the faster clock except in certain applications. You also have to you out of your way to test two different configurations for stability and you can't set different voltages for them. Heat

I have an old school Coolermaster Stacker 830 case and all the front bay blank plates have a grill that holds a small bit of filter material.

You say you used a thin layer of sealant to reapply the IHS, did you remove all the old crud? And when you say it's air tight, it's supposed to have an air gap - not be completely sealed.

I'm just confused since I got a pretty remarkable idle improvement but I can't get these load temps down at all. I was hoping I could get the temps down since it got to 4.5ghz stable without increasing the voltage at all. Delid?

Pretty sure this was the video that sealed the decision for me: https://www.youtube.com/watch?v=xNAMxZgvves From what I remember Putting the radiator on the exhaust causes an increase in CPU temps Putting the radiator on the intake causes an increase in GPU temps, because you're heating the air coming into the case What bitwit found in that video is that putting radiator on exhaust caused a much larger increase on the CPU vs the increase on the GPU that you get from putting it on the intake. Basically put radiator on front intake and use rear and top as exhausts

Endymion FRS MK1 posted:How necessary is delidding to get an 8086K to all core 5ghz? The last thing I overclocked was a 3570K so I'm very out of practice I'd strongly suggest it, the temperature difference is stark. Many people report a 20 celsius drop under load.

Delidding my 8700k was shockingly easy, but I was able to 3D print delid and relid tools. Kaby delid tool Kaby relid tool The nice thing about the delid tool is that it just needs a vise. I used a small 3-inch clamp-on vise from amazon. It does feel tense when you are waiting for the pop, but it works as advertised. Clean-up of the stock TIM is easy, alcohol swabs help. I used a tip from some youtube video and masked a rectangle on the IHS using scotch tape. Made the application of the liquid metal really easy. Apply it to the die of the CPU as well. Conductonaut comes with a black q-tip that helps. The silicone for re-sealing is really just an adhesive to stick the IHS back on. The stock seal has a deliberate gap so it's not even meant to be airtight. Just use a minimal amount and stick it back on. Without the relid tool, you could use the socket of the motherboard to line up the IHS.

Endymion FRS MK1 posted:Ok I'm slightly scared about my PSU. My 8086K is at 5.0ghz 1.3v, and I noticed during Prime95 testing that it hit ~260W under an AVX load, and only like ~170W (I think) under non-AVX. That's kinda scary, since I chose a Seasonic Focus Plus 650W PSU. I know that PSU calculators say I should be fine since worst case heavy AVX I'd be at 440W for the CPU+GPU (260W+180W) and not much more for a total of 4 fans, 2 SSDs and a 5400RPM HDD. Did I make a bad choice? Should I exchange for a 750W? When I got my 8700k it wouldn’t even boot properly with a seasonic 550W. I had to buy a 750W. That being said, the whole point of the prime95 run is stress testing and if the system isn’t failing then why would you exchange the psu? If you plan on adding hard drives or a beefier video card then maybe

I was able to get mine up to 5.0 at that voltage, but it wasn't stable with prime95. I was able to play hours and hours of counterstrike before crashing last night and finally dropping to 4.9 with the same voltages, it's stable with prime95 now. The 8700k reviews last year that said "we can do 5.0 at 1.33v on air!!" are basically bullshit imo

n.. posted:Any way to mitigate that with settings or is it a lost cause? I don't know, I don't really understand what you're going for. LLC is to counteract vdroop at higher voltages so that the proc stays stable at higher frequencies, it seems like you're undervolting so maybe you don't even want LLC. The only really solid advice I got regarding LLC was following along one of gamersnexus's livestreams where he was OCing an 8086k (I've got a 8700k) where he said if you set LLC to the second highest setting that should get you closest to bang on your manually entered voltage. I think he was using a gigabyte board as well so the second highest LLC setting has worked for me nicely. For a better idea of voltages check out silicon lottery's tables, they were pushing 8700k's to over 1.4v to get them stable. They don't seem to have data for 9700k available.

Running the prime95 blend test for an hour so far and the highest temp I'm getting is 85c, is that pretty high for that particular AIO with that voltage? I feel like it should be lower but I don't know exactly. Aphex- posted:I played a few hours of BFV yesterday afterwards and saw the max temp as 89 which to me seems a little much, I might reapply the thermal paste as when I installed it, I did have to remount it which may have caused some air bubbles. I'll probably play around with the fan curves too, and possibly after that try and reduce the voltage slightly just to see if that helps. Sorry for the late reply, I'm also running a 8700k and those temps seem high. 4.5ghz is a pretty modest OC. You'd be able to drop 15-20c by delidding. When applying the new paste, use a pea sized glop or the line method and let the paste smoosh across the chip, no air that way.

Aphex- posted:The top panel on the H440 has some soundproofing foam inside it and the only exhaust for air is like a thin strip along one edge of the panel so it seems like the radiator just dumps heat onto itself and only gradually lets air out the side part. From the looks of things there's probably about 1cm of space between the top of the radiator and the soundproofing foam. When I was deciding radiator placement I watched this video https://www.youtube.com/watch?v=xNAMxZgvves Not everyone agrees with this but it was enough for me to go with front placement

SuperTeeJay posted:I had to flex the motherboard a bit to get it out of the case so maybe the heat spreader shifted slightly with the cooler. (The delidder used liquid metal and reattached the heat spreader with a material that he described as elastic.) It's actually a bit of a nuisance that this is only affecting a single core and the cooling is still mainly effective as it means that sorting this out isn't worth the risk of bricking the CPU. There's a good chance the heat spreader is ludicrously easy to remove now. Most people just use RTV silicone after delidding which is way, way less adhesive than whatever the stock goop is. If you get some fresh liquid metal and re-do the application, chances of bricking the cpu are pretty low because the mechanically stressful part (delidding) is done already.

Spacegrass posted:I have a Dell Optiplex 790 and my bios doesn't have the overclocking ability. I've used just about every overclocking app i could find and none work on here. Is there a modded bios you could recommend for this system? My processor is a sandy bridge intel 2400. My motherboard is a generic stock from dell (0D28YY). Or should I not even not attempt it? Trying to overclock with a non-K cpu and a OEM motherboard like that is a total crapshoot but you might be able to pull something off From here: quote:What's this? The good news is that the rumors of Intel killing overclocking for non-K Sandy Bridge processors were slightly exaggerated! If you've got a CPU with Turbo Boost functionality it can be overclocked!! The bad news is that it's pretty limited. Our Core i5 2400 is rated at 3.1GHz with a typical Turbo speed of 3.2GHz with four active cores, with an absolute maximum of 3.4GHz under a single core load. By changing the Turbo multipliers to the maximum allowed either in the BIOS or the Intel Extreme Tuning Utility and raising the power consumption limits to 135W we were able to get the Core i5 2400 to run at a solid and steady 3.6GHz with a full 4 core load. 2 and 3 core loads are allowed to run at 3.7GHz and under single core loads Turbo was allowed up to 3.8GHz. These are noticeable increases in speed and only added about 15w of additional power use. It was on default voltage as well. So you might be able to bump up turbo multipliers using intel extreme tuning utility to get some extra MHz. I severely doubt it's configurable in the Dell BIOS.
