Hello All,

Have a look at this guide re overclocking.

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Well Wozza, I did all, and with the CPU offset atr 0.005, Win not boot ok. I increase the offset to the next step ( 0.10 I guess) and now is OK. I will check for stability. BTW what you do to acces to the primary timmings of the ram?? Im going crazy and I cant see this option !!!!I know is there but where???

It's in ai tweaker then click dram timing

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Ok, I find the Timming setup. I must tell you all is working very nice. at 4.5 ghz under loading. Let me ask you , will not be any better keep the 4.5 GHZ continously? even with light or not loading ??I allways did that with my old 775 system.

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Just another question Wozza . As you see between my VCCIO and VDRAM; I have a differance a little bit higer than 0.5v . It,s not that dangerous???

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

no your fine,and its better to use speedstep where cpu uses less speed/power at idle and full speed/power when stressed,

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

I have asked that couse I have read it must be very important keep that differance ( 0.5v) between both VCCIO and VDRAM. Away from that can u recomand me a good quality 2x2 gb of RAM for SB ?

yes your right but i dont know if it applies to sb aswell,it did for x58 boards/cpu's,if ram voltage is 1.5750 and vccio is 1.62v your within .5v so thats ok,it only if your outside of .5v

this ram works good

Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CL9 1.5V Non-ECC Unbuffered

or this if you have a huge cooler and need clearance/no heatsinks on the ram,its the same but without the big heatsink

should work fine

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Just curious, how much voltage is the cpu using running prime95 or IBT? I gave up on the offset mode and went to manual @1.28v. CPUz says it uses ~1.288v under 100% load. Using offset mode I was running with a lot more voltage.

[ea3ot]

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Same as me. In the ofset mode the CPU-Z reads Vcore 1.32 if not more or something like this

[wazza300]

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

1.36v for me,probably uses more in offset to compensate for vdroop? idk,but you nearly always use slightly more,trouble with using a fixed voltage you have to run cpu at full speed/voltage all the time

im finding the new bios to be much more stable though

[Ken429]

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

Yeah, but what does the cpu voltage jump to when the system is under 100% load (prime95 4-cores, 8-workers).

[wazza300]

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

1.344v,i could lower llc level and use more offset but havnt really played yet,this coolers limiting me to 4.5ghz max,i hit 79c too,if i were you ken id flash to 3203 bios,i find its better

what wei you get with that ram? i got 7.9 just after updating bios but its gone back to 7.8 now,cas 9 timings though

[Ken429]

Re: Asus Z68 V PRO 4.5GHZ Bios Screenshots

That is why I went to setting the cpu voltage to Manual - the cpu temp went over 65C under load. Like I said above, the max voltage I see under load with the Manual setting is ~1.288V and the max cpu temp after running prime95 (4-cores, 8 workers) for several hours is 62C. I also have Load-Line Calibration set to Ultra High and Phase Control and Duty Control set to Extreme.
