Everything else being equal, the high ASIC card will be able to push more core clock than the low ASIC card. All things being equal.... It's not the final say in how well your card will overclock, because of everything else that plays into it, but it IS an indication of the silicon you've been dealt.

Well pushed my own 970 to see what points i would get out of it when pushed to its limits on stock bios.

+87mv
110% power limit
+230 core clock ( 1558.3 mhz )
+ 640 memory ( 2065.5mhz )
100% fan speed ( not needed as temps where like 52c but oh well ).

Old cpu i7 870 3990 mhz.

And this is what i got out of it.

First time i broke the 14000 gpu points, faster then both my 290's in single solution with heavy unstable overclocks, so yea gg. Can't really push much further anymore as the driver will crash, this is the max i can go without changing bios settings. I don't think it's going to be stable for gaming tho, i do have a stable overclock solution that scores 13800. So not really a big issue.

I'm really impressed by this 2500k, still going strong since 2012 ! It's not even worth upgrading to skylake for gaming, would cost a lot of money for a small gain...
Too bad my 1155 mobo is ugly as hell and doesn't have SLI support tongue.gif

Core i5 760 still only just a very little bit holding me back. at 3911

Can you guys take at look at this Bios for me and help me out?. I cant get past 1540 on the core. I really dont know much about Bios mods. Its set 1.28 volts, which is supposed to be over the 1.275 limit on the 3975 KR card. I was thinking it has something to do with Bin settings? IDK. The damn Ram is great, 8280. But the core needs some help. PWR is also not an issue as I have it set to 300W and with the slider on AB it goes to 149% yet it never goes over 109% under benches. What do you guys think? XENO1.28volt.zip 136k .zip file

Also at 1.26 i can get 1540 core. 1.275 i can get 1540 core. So whats that about?

GPUz and PCX won't report anything over 1.275v. Some guys swear that the SC / SSC models will go above that 1.275v and have 1.281v bios versions running on their cards, but....I personally don't believe it. Not until I see a mutlimeter reading 1281mv going to the GPU.

I tried EVERYTHING with my FTW to get it to go above 1.275. I ran stress test after stress test at 1.281, 1.286 and 1.312...I didn't get any changes in temps, no changes in power usage, and no changes in stable clocks. There was absolutely no changes in anything.

So....do your own tests and see if you notice a difference. About the only way you're going to tell. Unless you have a multimeter handy...and know where to probe it. = )

Yeah i agree with everything you just said. I only uped it to 1.28 to be sure it was over 1.275. My neighbor is electrical engineer but he has no time to muck with this stuff. The question is can I get past 1540 because of BIOS settings that I have not tweaked? I have very little clue on Bios modding. It seems that you Blaze,THEBOOM and DarkAngel do.

The next thing I would suggest trying is setting the TDP Base Entry, 3D Base Entry, and Boost Entry to: Entry 0 (disable boost), and up the base to 1455 or something. I have mine set to 1531, but if you're having problems getting that high, I'd probably go more conservative.

Then, in PCX, try enabling KBoost. That'll lock in the boost clock and the boost voltage for your card. I've found that it helps me keep the higher clocks a little more stable. Like disabling C-States when overclocking a processor to it's limits.

If you're on air, you may also want to consider upping the temp target to 86. Your settings is pretty low there, and if it reaches that temp, it'll throttle. That could be a contributing factor in what's holding you back.

Maybe something like this:

thanks. Most of what you said is beyond my ability. i have never had a temp issue. its never been above 74c. It never will get much higher. Once i set my OC profile I ALWAYS Crank to fan to 100% My temp MAX settings are at 91C. it never even gets close to that

I dont know how to set the entries you suggested. I just took a Bios that THEBOOM set and modified it slightly to have more voltage. thats the only tweak I did .

I left everything as you had it, except for the base clock. I raised it to 1455. I would seriously consider trying to use KBoost. It may help. Some people don't have much luck with it, for others, it makes a world of difference.
