CPU Overclocking (3570k)

[skater7429]

Hi, so I'm new to overclocking never have b4 but i wanted to give it a go so i did a bit of research ob how i should go about it and I've managed to get 4Ghz at 1.175 volts. I wanted to know if that voltage is good for the particular overclock i have given and just a btw i can't go any lower on voltage as i get an error in prime after 10 minutes or less.Also is there a way to lower idle voltage ?

The best way to find out if you have a great 3570k is if you can run 4.5Ghz at 1.2V, which it looks like you won't be able to. You can lower the idle voltage if you do an Offset overclock. Offset overclock are more difficult than a Fixed overclock. A good way to start is to find out what Fixed voltage you need for your clock speed, then hop back into BIOS, set the Offset Voltage to + or - depending on what your VID is under load. So if you have a VID of 1.226V and you need 1.336V, set your Offset to +.110V

GL!

Almost forgot. Copy and Paste this somewhere safe!

BSOD Codes for IvyBridge

0x101 = increase vcore

0x124 = increase/decrease vcore or QPI/VTT... have to test to see which one it is

0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore

0x1E = increase vcore

0x3B = increase vcore

0x3D = increase vcore

0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage

0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances

0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x

0x109 = Not enough or too Much memory voltage

0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)

0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

thanks 4 your reply going 2 try an offset oc now and see how that goes

[skater7429]

Got it to 4ghz using an offset oc and it only consumes 1.152 on 100% load with my hottest temp on a core being 67 degrees is that acceptable or should i try to get it down some more ?

i would go lowest that can pass burn test/prime95 and heavy load tests but if i were you i would overclock it bit more it seems like u can achieve 4.3 with around 80-90 degrees once you are done with clock try lowest vcore u can get on that

[skater7429]

Taking your advice and got to work testing bigger offsets and seeing less voltage been drawn at full load so i think there is room for improvement but i havn't run prime for long enough to say this oc is stable tho. Will update thread with final result when finished and thanks for the suggestion as well.

67C under load is very good. You're fine until you hit about 80C. I'm betting you could get 4.2Ghz from what I see in your avatar. (try not to hit 90C!)

Edit: You may need to raise your Load Line Calibration in some point, if you haven't. Idk which mobo you have, but you could Google and find the most useful level of LLC. You want the level that won't allow any Vdroop, but at the same time doesn't add excess voltage.

Since you're just going for a small OC, you could prolly just leave it alone :P

[skater7429]

The best so far

Nice temps. Are you going to go further? You could. (should)

[mgsstar]

The best so far

Yea I agree with Wats. I think you can push it a bit further... But if you think its fine then stay with the configurations that you are using now.

[skater7429]

The best so far

Since I'm still pretty new to this i didn't want to push it too far but this weekend i will try for a 4.4

I hit a brick wall trying to get it to boot at 4.2 without giving it alot of voltage i got 4 ghz stable using an offset oc of -0.160 but to get it just to boot into windows at 4.2 i have to change that to -0.090 and then that draws 1.200 volts under full load but that isnt stable as prime crashed after about 10 mins ... Why is it taking so much more volts just to get 4.2 ??

I think each CPU is different and they overclock differently. Some might need more voltage to get to 4.2, but some don't.

[skater7429]

I know that all are not the same but considering how little voltage I needed for the 4ghz i thought i would be using much less voltage to get to 4.2 .Seem to have a stable oc at 4.2 now but will test it for longer tomorrow to see if it really is and i don't think i will be going any higher on air cooling.

[Wats]

Oh, you must of forgotten LLC. Raise it up a bunch, not all the way, but the 2nd option from the max. (IDK what MoBo you have)

[skater7429]

I have an asrock z77 extreme 4 and the highest is 1 i think ... right now i have it on 5 and the reason for that was that when i raised the llc it was giving me mad voltage on idle but i will try what you have suggested and raise it again.

[skater7429]

So i thought my 4ghz oc was stable then today i get a random bsod but its been running fine the whole week and prime didn't crash after running it for 6 hours . So does this mean my overclock is really not stable then ?
