Hi there, I've had my CPU stable at 4.2 for a while now, and i have tried for 4.5 in the past although I've never managed to get it stable. The problem i found was it would cope under a stress test but the moment i stopped the test (prime 95) it would hang.

Spec:
3570K
16gb (4x4gb) Geil Dragon Ram
ASUS P8Z77 LX
ATI 7950

The current settings i have on 4.2 (from ASUS TurboV EVO) are:
BCLK Freq : 1.050
CPU voltage: 1.020
DDR Voltage: 1.500
VCCSA Voltage: 1.050
CPU PLL Voltage: 1.8
PCH Voltage: 1.050
CPU Ratio: 42

Digi+VRM settings:

could you offer any advice to help me get to 4.5+?

Thanks :)

at 4.2 im not sure you need to play with llc, im running 4.3 on my 3770k at regular. Are you running auto and offset vcore or manual, also what are your temps and cpu-z readings?
 
BCLK Freq : 100
CPU voltage: 1.3
DDR Voltage: 1.500
VCCSA Voltage: 1.050
CPU PLL Voltage: 1.65 or 1.9
PCH Voltage: 1.050
CPU Ratio: 45

Try that and see if it's prime stable, if not up vcore slightly, if it is drop vcore slightly till it becomes unstable to find required voltage

You can leave the CPU LLC where it is, won't do any harm

What are your memory timings?

I believe i did an offset on the vcore, i originally overclocked using BIOS but have just installed the ASUS software for simplicity at the mo.

First image idle, Second under load

highest core maxed at 71 degrees after a bit of prime 95, and the memory is at standard timings, which is 11-11-11-28 at 1600mhz.

should i try the settings recommended above, baring in mind that i did an offset in the bios, would that affect anything?

Thanks

e: the Core voltage on CPUZ when idle is bouncing around a fair bit, between 0.016 and 1.240, is that normal?

the voltage in cpuz is normal its a real time reading like with your speed ie at 1.6 it will be lower at 4.2 higher. So the real vcore voltage is 1.264 not 1.020. What offset did you use? Im guessing 0.05 was it?

also what cooling are you running? air, water, if so what etc.

That is positive offset so more voltage. My 3770k is running 4.3 on a negative 0.005 offset. I would reset that back to 0 reset llc to normal, bump to 4.3 and see what happens tiny steps and all lets see what she can do at stock. What does coretemp list your vid as?

Ignore core temp and read cpuz for the voltage
Remove offset, leave llc where you had it
Set vcore as 1.3 and multi as 45 as mentioned above

using the 0% LLC and a -0.05 offset and it still seems stable at 4.2, with 1.192 Core Voltage on cpu compared to the 1.264 previously.

im looking for a good constant overclock, is 1.3 a good idea for that or do you mean try them out as a starting point and work down from there? i will give it a go now though and report back, thanks :)
 
whenever overclocking always go up in steps your at 4.2 next step is 4.3 try it test it make sure its stable than move to the next step

One way of doing it, or just try it and adjust
If you want 4.5 set it and see what vcore is required whilst keeping temperature below 80c

You mean the safe way. You dont neck a bottle of vodka first time drinking just to see what happens then work your way down. You start off with a couple of beers and a shot to see if you can hold your drink first then move up to the point of being sick lol
 
I had no luck with trying 1.3v at 4.5, I think I prefer using the offset anyway, although so far its gone from 4.2 with -0.005 offset to needing +0.040 offset for 4.3, currently testing it now

e: do you think the optimal point for my cpu is to just keep it at 4.2, or is it worth trying for that bit extra?

Lol I think you're wrong with that one as well, not how I remember being at 13

As I say I need 1.355 at 4.5, as long as you temps aren't a problem its fine

ah okay, i think ill try working my way up there with the offset either way though, thanks :)

seems stable at 4.3 with a +0.050 offset so far, I'm not sure if that's good or bad though, as it seems quite a jump from -0.005 from 4.2 :confused:

either way, I'm going to see how it gets on with 4.4 now :)
