P8Z68-V-PRO+i7 Strange Results

post #1 of 4
Thread Starter 
After updating my bios from 0501 to the new 0801 i did get better overclock results on my i7 2600k ( lower voltages ) like 4.8 ghz @ 1.328 and 5.04ghz @ 1.416 . My 4.8 settings..

My CPU Settings are:
Load Line: Auto
Power Phase : Extreme
CPU Capability: 110% for 4.6~4.7 and 120% for 4.8
CPU Voltage Mode: atm AUTO on OFFSET. I WILL SET MANUAL TO 1.35 ( for 4.8 )
Spread Spectrum: ON
VRM Frequency: I left it on default ( 300 ) since i don't have problems with it. If needed be i will set it to 350.
EPU: is left on default and profile maximum performance
**WARNING** Above settings are from bios not ai suite . I prefer bios OC.

My problems so far are my memory dimms. I used to be able to oc them to 2197 or 2300++ now i can't boot and get OC fail if i go above my standard XMP profile of 1921(standard 1866 for blk 100, since my blk is 103.0 by default and it's x7 multiplier ).
If i select 2197 ( standard 2133 for the blk 100 ) i can't boot anymore and i have my memory debug led on.


Any advice on my CPU and RAM Oc would be much apreciated . I can't figure it out why my ram won't oc anymore to 2197. It was at 1.56-1.57 voltage at that frequency so it was well under the danger-zone 1.6-1.65.

First off, congrats on the oc. I have this board and a 2700k incoming, so this is encouraging. My guess is that the new bios retuned the board so to speak. Sounds like you were at the bleeding edge of performance on the ram side already. Maybe the board retuning has given up some ram performance for the sake of lower voltage on the cpu. Have any of the chipset voltages dropped as well if you monitor them from the windows utility? Can you pump in a little more voltage there or into The ram? What do the release notes on the new bios say?

Edit:deleted. What about disabling spread spectrum and setting LLC manually to ultra high or extreme. Doesn't ultra high net almost 0 vdroop at load? Given the cpu ram relationship, do you think its possible that lower cpu voltage could result in slightly lower vdimm voltage causing you ram to fail?

I don't know exactly . I will try and turn spread spectrum off :z and set load line C to ultra high. The ram bit it's very wierd. also got a bsod now on 4.6 ghz and auto voltages ( was testing to see if ram is stable now with more voltage as auto voltage lets the cpu get to even 1.401 volts at 4.6 at it's xmp profile of 1866 or 1921 in my case ). This is getting very wierd :z. Thanks for the reply.
