Just bought this to go with my ssds and evga 980 sc, and I'm getting very low scores in 3Dmark and tomb raider benchmarks, I tried to of the 6700k too but in Windows cpuz shows the oc but as soon as any load is applied the multiplier goes to x39.9?

3Dmark fires trike score was 9299.
Tomb raider was average 29fps on same settings my 2500k at stock got 71 average.

I have just reran 3dmark with the evga precision overlay on and the 980 wasn't even getting up to full clock speeds? Gpu sat at 300mhz on most tests?

Could I need a better psu than the corsair vs550? Or am I missing something?

Also on real temp and hwmonitor my temps for the 6700k are moving between 14-33 every second on all cores and can't get a stable reading? I reseated the cooler and re did the Icdiamond paste.
 
I was getting poor performance from my 6700k initially, fixed it with a fresh install of windows to clear out old drivers etc. Probably a silly way of doing it, but worked.
 
I fired up squad after initial install (which is CPU heavy) and was getting the same 20-30FPS as my AMD 8320. After fresh install it went straight up to 50-60FPS on epic settings. Much better.
 
so after running heaven and comparing my results with other 6700 and 980 users it appears them results are fine and in line where they should be also 3dmark is now scoring 12789 which is where a 6700k and 980 should sit apparently

so just when stressing the cpu does it clock itself down to 39.9 multi and i cant seem to keep even a 4.4ghz all core overclock on, as soon as prime95 or aida64 run the 4.4ghz goes to 3.99ghz .... PSU not sufficient is a thought thats been thrown around?

Whilst not the best, I don't think your PSU is your problem, unless of course it's borked.

I have run an overclocked 4690K and a 980ti on my Superflower passive 500w PSU, power meter says it draws no more than 400w from the wall when both CPU and GPU stressed 100% which never happens outside of benchmarks.

I had problems with temp monitoring software when changing CPUs, try uninstalling them and reinstalling them to see if the temp reporting issue is cured.
 
So still trying to get any form of overclock on this chip is impossible. As soon as a load goes onto the chip it knocks back to a x39.9 multiplier.

I have tried the auto oc settings in the bios and manually setting x43/44/45/46 with voltages from 1.35-1.4. Doesnt make any difference.

Is there something simple im missing to enable the overclock to stay when loaded? It shows the overclock in realtemp and cpuz right until a load is applied then drops to 3.997ghz
 
if it's like the 4790k which I believe it is, 4.4ghz is for 1 core only re-run cinebench on a single core you'll see 4.4ghz on all cores it'll be 4ghz of course you could set it up in the BIOS to run on all 4 cores at 4.4ghz which I doubt would need any additional voltage
 
base and turbo i set to x44 or above? should i disable turbo and set base to 44?

using aida64 stability test and setting to x45 for example it goes from 3997-4500 but averages around 4250mhz.

prime95 goes down to 3997 and stays there

***edit***
Just disabled turbo and set the multi to x45, still clocks down on both aida64 and prime95 :(

On my asus board, if I have turbo disabled it runs at stock clocks, regardless of the multiplier I set, so I have to leave turbo enabled. It then runs at 45x so 4.5Ghz 24/7
 
how strange, just rebooted and set x45 and enabled turbo and all 4 cores to 45.... downclocks to 3997 in prime still and aida64 the clocks go from 39.9 to 45 and move inbetween. Average in aida is 4250.

really confusing myself here
 
If an Intel CPU downclocks when fully loaded, it is usually because the turbo power limits are set too low in the bios. These Intel CPUs use turbo boost to reach the maximum multiplier. Increase your turbo power limits and this will prevent the CPU from downclocking.
 
Is your windows power setting set to high performance? I had a similar issue and it was due to having power saving selected.
 
Turbo needs to be enabled, what are your max temps?? Sounds a bit like a throttlling issue. 1.4v is too much for an air cooler. Most 6700k cpu's have a vid in the range of 1.25v-1.3v and most of them will hit 4.4Ghz at there stock voltage. So check yours in bios, clr cmos first and check then set that voltage as fixed vcore, so if its 1.285v set that with a x42 multi and test with something like asus real bench, if it passes, up the multi and test again, keep going till it crash's, if you have temp headroom,( max i suggest is about 80c give or take) increase voltage a lttle and test again.
Oh and ditch the ICdiamond its crap!
