So close.



Left it going while at work. I know if my IMC voltages are off at all it BSODs in less than half an hour, so for it to drop one thread after half an hour and the next two over longer periods of time but leave one running for 7.5 hours I'm probably running into thermal issues with the RAM that I never will in day to day use.

I've got one idea that might help, but I'm going to try out a more general stability test like x264 that's not hammering my RAM quite as hard.

I think that would save you alot of time and headscratching yeah lol.
HCI memtest is so difficult to get 0 errors, while for normal use the settings might be perfectly fine.
Just run some benches and do some gaming, actually enjoy your tweaked RAM tongue.gif

I've got this crazy notion that getting some sort of "perfect" overclock will suddenly allow me to drop vcore 500mv and run 6ghz.

Only half joking. I do think I can perfectly stabilize this though. I've got stable profiles to game on. It's just that this is the most fascinating puzzle I've ever attempted.

I have been tweaking my ram/cpu also.

I had trouble with anything over 2400mhz, but it was the io voltages that was too low. +250 IOD/+225 IOA solved that problem and ram tweaking became much easier. I also got the cpu stable at 4.7/1.255v (I usually use 4.8/1.33v, but it's summer here and i wanted less heat in the loop).

I've been gaming on this overclock without any issues. But I still have some issues with reboot loops when i restart or start the computer, but it will boot eventually.

Your CPU is a full 3 bins better than mine.

I hate you. +1 rep

Guessing 4.8 at 1.3v is a good thing then huh? Im only using 4.5 at 1.2v and its been stable for a couple weeks now. I tried 4.8 at 1.3v and was stable i just didnt see a need for it for gaming.

biggrin.gif I got some ideas and saw some screenshots here. Your cpu can atleast handle 2800 mhz ram, mine can't do that. But i'm more than happy with the performance at 2666. I also did 1h of realbench at 4.9/4.5 cache, takes a lot of vcore (1.405), but it's totally doable. (can't upload screenshot for some reason)

For a 4690k it's pretty close to golden as far as I know. And on the opposite end of the spectrum we have my core: 1.135 stock VID, needs almost 1.3v just to hold 4.5.

Well, mine can boot 2800mhz ram. Remains to be seen if I can fully stabilize it while maintaining max core clock. And your 2666 1t is putting numbers up about in line with my 2800 2t.

What kind of vccin did you use for that 1.4vcore?

Sweet, probably doesnt hurt that i run bare die. It stays under 50°C at all times with 1.2v. It was stable at 4.2 1.088v and 4.5 1.2v and 4.8 1.3 (although i only stress tested that for 30mins just for the hell of it, at 4.5 and 1.155v it wouldnt last more then 5mins either restarting or giving me a BSOD)

Im curious as to whether shes stable at 4.6@1.2v i wouldnt mind that at all. And i always check with a DMM at the VCORE check points on my MSI mobo, far more accurate testing. Goes from 1.196 to 1.200 when stress testing.
