Overclocking help with EX58-UD4P and i7 920
« on: April 27, 2009, 02:35:39 pm »
Hi all.  I seem to be stuck at my 3.2 OC and am not sure the steps moving forward.  I am trying to get a procedure like Gunrunner requested here- http://forum.giga-byte.co.uk/index.php/topic,176.0.html.  I guess my first question is if the procedure would be the same despite the difference in mobo? 

If not then I would like to get the steps needed to ramp up from 3.2 to 3.8/4.0

I have killed several small trees printing out all the information I have found so far on OCing. I reviewed the guide here but had some concerns setting any of the voltages in the pink.

One thing to notes, is that my OCZ DDR3-1600 memory does not have XMP settings so to get it to run at optimal speed everything must be set manually or it will default to 1066.

I found another guide that found a stable OC at 3.8GHz with safe voltages, but I only made it into Vista one time before BSOD to a 101 error.  Now it just goes directly to a different BSOD and reboots too quickly for me to even
read it.

Here are the settings I tried for a 3.8 OC:

turbo mode off
CPU multiplier 19
BCLK 200
CPU voltage 1.36
QPI Voltage 1.35
CPU PLL 1.8
all others set to auto
Dram voltage 1.64
Memory timings set manually with a 8X multiplier and 7-7-7-24 2T TRFC 88

My goal is to get the highest combination of CPU/mem speeds that is stable.  If I can get 3.8 but have to lower my mem speed that is ok.

Please help!  Thanks in advance.

Try 1.4V for CPU voltage, and see if that helps. Also, some people find it easier leaving turbo on with 20x multi for a 21x multiplier, so a lower bclk is needed to get the same clock speed, as there might be a wall on the motherboard. Try 21x multi and 190Mhz Bclk to see if that has any improvement.

For more advice try www.ocforums.com, just copy this text basically and there are many people with core i7 920's to help you with.

I guess this is a C0 right?

I do not want to go over the safe voltages for anything, so nothing in the pink.
Yes, it is a C0/C1
