Rig Builder done.

Thanks. So if you are convinced its not the GPU... It's at stock clocks, right?
Without just guessing at sht, we need to see your bios settings. Format a usb stick fat 32, post with it in and hit F12 on each bios page, scroll where needed and post them here (please use the "paperclip"). Or if you have done this already, what post #?

I will try and get screenshots of the bios tonight. Thanks for the replies so far!

Changing the LLC to Level 2 seems to have increased stability, running about 3 hours in and no game crashes. Stable with 1.176v @ 4.5ghz!

Here in the guide recommends enabling this option, but really in my PC always stops working after about 20 minutes on Prime95.

I tried the version 27.7 and 27.9

What this option actually does, and why the program stops working when this activated ??

That's weird because according to the maker of Prime95, that option is automatically enabled when you Torture test your system. The only time it can be enabled/disabled by the user is when crunching Prime numbers.

hi guys.

Finally I OC'ed my i5 2500k to 4.8Ghz, I think that My CPU need a little more voltages than others 2500k.

My CPU need 1.448v for the 4.8Ghz, I want to ask if that voltage is good for 24/7 use?????

(the max temp was: 75 degrees using a thermaltake frio (AIR)

thanks thumb.gif

My CPU needs that exact same voltage for 4.7GHz so I think yours is on the average.

Can you take screen shots of your bios and post them here? Format a flash drive in FAT32, reboot into bios and hit F12.

There is nothing wrong w/ negative offset, its no worse then positive offset. Its just another way to adjust your voltages and fine tune your system. It also depends on what multiplier your trying to get stable. With your multi set at 43 or lower you will more then likely be using the negative offset to bring your voltage down so your not overvolting your CPU.

Yeah I got it for the offset. By the way I found that one level correspond to ~0.016 -> 0.024 v compensation.
I'll try to reformulate this question.
Assume I found that my cpu can run stable at X Mhz for a vcore of Y volts. I could have different combinations, that will all give me what I need :

vCore offset : +0.005 | +0.005 | -0.010 | -0.010
Turbo offset : +0.020 | +0.004 | +0.004 | +0.020
LLC : 4 | 3 | 2 | 3

And so on.. When you want to lower vcore, is it better to lower the base offset (in respect to the idle stability), the turbo offset, or to raise the LLC. All three have the same effect. Same if you need more vcore.

I'd say it's better to try to have the minimum base offset (staying stable idle) since it will lower energy consuption and temps. Don't know about LLC.

If it's of any importance... biggrin.gif

Also what is the vcore displayed in the BIOS ? Guide says to set the LLC level to the one that will make you closer to the BIOS vcore.

I'll make screens when I can.
As an example yesterday with +0.005 offset, +0.004 Turbo, LLC 5, 4.2Ghz :

- BIOS : 1.144
- idle : 1.080
- load : 1.280
- Max temp : 70° (OCCT, but not linpack, so not that hard on the cpu)

Yes, it's a vcore vs load graph.
