the guide prefers prime95 but if i were to test with intel burn what settings should i use?

you should use the extreme setting. although i wouldn't bother with IBT, although it does shoot up your temperature to the highest, even higher than prime. the latest version of prime95 still is more stressful. IBT will be a good indication of thermal, while prime will make sure it's fully stable. just my 2cent.

X2. Not a fan of IBT use P95

Hello everyone

I have been reading this site for years and finally registered myself. So I'm back to overclocking CPUs, last time I did some it was my old Q9300. First, thanks for the awesome guide. I've been trying to understand and follow it, Im sorry if I have done something wrong.

My setup:
P67 Extreme 4
G-Skill RipJaws-X 2x4gb 1333MHz 9-9-9-24
i2500K + Thermalright Silver Arrow

So I started by setting all the BIOS settings right like the guide showed. I put the multiplier almost straight away to 40 and then 42 with having offset +0,005v and turbo boost +0,004v, LLC level 2
-> That put my volts automatically pretty high. CPU-Z was showing 0,984 to 1,1v idle voltages and max was 1,344v in Prime95 temps max 56C

I tried to lower the voltages by setting offset to -0,035v, but it doesn't seem to do anything. Should I lower the turbo boost voltage, or just lower offset more?

As you can see, my voltages are a bit high for 4,2? Temp max also 65C now after ~20min. Weird, earlier it was max 56C after +1 hour...guess I changed the Prime95 settings match the guide's settings for this run and it spiked.



I'm dreaming of going to 4,5GHz with a reasonable Vcore and temps, then put it to do Prime95 for the night. So I guess I'll just try to lower the turbo boost voltage next? How low should I go?

E: Oh wow. I feel like a complete retard now. Yeah...you cant lower the turbo boost voltage...seriously misunderstood part of the guide. So I just lowered the offset voltage more, it's -0,040v now.

1,320v max
0,928v min

I wonder if I lower it more to get the load volts down, the idle volts are beginning to be too low?

you cant go any lower than .004 turbo, but you can continue to lower the offset, and try using llc3 or 4 or even 5 to allow more vdroop. You will experience seemingly larger spikes, but the spikes are short lived that it does not really affect temperature. save llc2 and llc1 for when you are spiking into the 1.4+ range

Alright, thanks inedenimadam.

I changed LLC to 3, then continued lowering offset voltage to -0,050, which resulted to idle 0,920v and load 1,272v. Ran Prime for about 40min, seemed good for @ 4,3GHz

Upped multiplier to x45, couldn't get to Windows. Tried upping offset voltage by little at a time. Set it to +0,005v and got to Windows.

Now running Prime overnight and let's see how it goes.



Not sure if I try to go any higher after I manage to get @ 4,5GHz stable.

You dont have to do it all at once. You can save the settings to a profile slot in BIOS and come back to overclock it further another day. On

Voltage is a little high for 4.5ghz. You should be able to get your CPU stable around 1.3v with a 45 multiplier.

Prime95 ran for like 11-12 hours now and it seems stable so far. Temps mostly 60-66C, max spikes 71C.

Yes, I agree the voltage seems maybe a bit too high. I have offset voltage set to +0,005v, anything lower than that and it won't boot to windows anymore. Turbo boost is +0,004v. So does that mean the idle voltage becomes too low so it won't boot? Sorry, but how can I try to lower only load voltage since you cant lower the turbo boost voltage?

I guess I try changing the LLC settings and see if it does anything.

E:

Woah. So I stopped the Prime95 test and was just about to try IBT, but got a BSOD before I even hit start. Not stable in idle? Damn if I need to increase offset to +0,010v. First I try changing LLC.

E2:

LLC level 4 lowered the voltages almost to 1.3v. IBT gave me a bluescreen after that, then it wouldn't even boot to windows. Back to LLC level 3 now. I guess I can't get @ 4,5GHz stable with lower volts than in the screenshot above.

Okay so ATM im back to these settings:

4,5GHz
offset voltage: +0,005v (any lower it won't boot to windows)
turbo voltage: +0,004v
LLC 2

Earlier I ran Prime95 for 11-12 hours like I said, same settings but LLC was 3. Today I continued by running with IBT and it gave me a bluescreen. I lowered LLC to 2 now and it seems stable. The problem is, my volts are now even higher than in the picture above(1,344v), because LLC 2 set them higher.

Idle volts changing from 0,976 to 1,072v
Load volts 1,352v

Doesnt seem to be the best overclocking one if @ 4,5GHz needs 1,352v. Well....Im okay with that if it's stable.
