Am I overclocking this i5 2500k/GA-Z77-D3H properly? I'm afraid I'm doing something very wrong... - Page 6

But it was crashing with Medium and low frown.gif I'll put my faith in you and try, though. I'll start with LLC in low, Vcore at 1.35V and increase if I get another 101 BSOD ok?

I'm thinking something: Vcore Voltage Response... Should we leave that in Auto? A guy above said so, but what if we change it?

It might have been crashing due to too low of a voltage.  With the High setting, you're getting vRise.  With Medium, there seems to be a tiny amount of vDroop.  With Low, there's more.  So, the voltage setting in the BIOS needs to be increased to compensate.

 

So, using a BIOS voltage setting of 1.35V with the Low setting will probably result in an instant crash of some kind.  You just have to experiment so that you end up with the full-load voltage that you know is stable.  It should get easier and easier the more you experiment around.

 

I don't know what VCore Voltage Response does yet.

In that case, just for caution, I'll change LLC to medium.

Will report back in this same post what I get

If you want to, you can try just setting the Vcore to Auto. For a 2500K at 4.5 the motherboard will probably be able to provide stability in Auto. The Vcore might be higher than absolutely required, but it will be safe and stable. Give that a shot and watch the volts and temps while you test it once. That should give you some idea of what a stable voltage is, and then you can work back down from there.

All the testing should be done under Prime95, right? We already saw IntelBurnTest just won't cut it.

Just wanna make sure before trying that out. BTW I'm running a blend test in Prime95 right now, been 6 minutes already, so far, it's all ok. I'll leave it running for 20 minutes before trying the Vcore at auto.

IntelBurnTest cuts it, but it creates too much heat.  When I was learning how to overclock my 2500K, I insisted that I was going to use Intel Burn Test.  I was taught by pretty much everyone that Prime95's Blend test is just as good since these CPUs have an Integrated Memory Controller.  Actually, the Custom Blend test is better because then you can tell Prime95 to use about 90% of your memory instead of the default of 1600 MB.

Ok, I've been running Prime95 in blend test for 20 minutes and so far, it hasn't crashed.

Shall I try with Vcore in Auto to see what happens (for 20 minutes) or just go ahead and run Blend Test with 90% of the RAM for 24 hours?

Current results of test 1:
Vcore running @ 1.35V
Voltage calibration set to medium
Core Voltage reported by CPU-Z: It was sitting at 1.344V all the time
Max temp registered at burntest: 76ºC

1.344V in CPU-Z, It was sitting there al the time.
