i72600k prime95 unstable@stock - Page 2

post #11 of 23
Thread Starter 
I researched a bit and posted on Corsair forums about the PSU, but it seems like a hot PSU is quite normal and so far I'm not blaming the PSU.

Actually. I take that back..

Look at your RAM's revision number... If it is 2.12... then there is nothing you can do. The 2.12 doesn't like to be overclocked at all. If it is 5.11, then you can push it to 2133 MHz with ease.

Cheers, I'll have to check when I get back home which revision they are. However, even if it IS v2.12 of vengeance ram, they're still rated for 1600C8 and that's all I've run them at.

And regarding my AS5, sure I know it needs 200hrs of curing time to reach it's max potential but I really don't think this is a cooling issue when temps @ stock are ~60C and the blend test still is able to produce errors.

Any suggestions?

Not sure if you mentioned it or what but what voltage is the CPU at? If you're leaving something as important as Vcore at AUTO, you might want to not OC... ever.

It's large FFT and yeah the voltage is rather low (1.5V).

I bought all the high quality components I have with the intention of overclocking to the maximum extent I could keep my system stable.

I'm having problems, so to isolate the issue I turn all settings to stock. Surely, intel's own specifications will suffice keeping the device running as intended.

Besides, setting the vcore @ auto accomplishes the task of making the CPU able to reduce vcore when idle, lowering temps further and being kind to your electrical bill. Not to mention making your rig silent when idle. Setting a static vcore doesn't do that; not on my board anyways.

My system has functioned quite well @ 4.4 @ auto vcore and powersavings enabled cept cstates which influence SSD speed greatly. Now, however, it seems something is wrong with my ram. Got any suggestions?

My advice is to find your own stable settings as far as voltages are concerned. It's not the quickest solution but it's the one that works. The easy way isn't getting you anywhere.

Ok so I checked my RAM and they are indeed v5.11. So you're suggesting giving them 1.65 and maybe even choosing a higher speed than 1600?

+1.

auto vcore will drastically overshoot the amount needed which in turn could degrade your chip.
if you dont want a fixed vcore, then use offset voltage that way it will drop back down to .9-1 vcore at idle.

and your ram could be a culprit with your OC stability. my previous kit was never stable thus causing me to get bsods all the time, changed kits and now i have zero issues and was even able to lower vcore quite a bit. (though the raising was prob artificial by me trying to stabalize a system with bad ram)

Yea you definitely have a cooling problem. Either check that you have even distribution on your thermal compound or look in to getting another heatsink / fan. You will also want to check your fan speeds in the bios to make sure that they are fully powered.

+2 on this. You should not be overclocking with vcore on auto. While running prime just watch you voltage in cpu-z, with it on auto you will see huge jumps, way higher than is necessarily. Just learn to OC like everybody else, it is a little time consuming and a little trial and error, but it works.
post #20 of 23
put yor vcore to 1.4v.

Run prime for 2-6 hours depending on how thorough you want to be. drop the vcore .05 and reapeat.

Do this until you BSOD in Prime95.

Or start at 1.25vcore and increase by .05.

That is the way to go; never Auto vCore; dangerous on components
