I'm using my P5W DH Deluxe to overclock my Pentium D 930. This will be my first set of serious overclocking attempts... As such, I have a few quesitons regarding this motherboard for those of you who have more experience:<br><br>
- I have noticed that when I select a lower VCORE in the BIOS before loading the computer, it will put the value in a blue background. This occurs until I pick a value higher than 1.25V. Is this because my CPU requires that voltage to operate normally?<br><br>
- When I select a FSB/VCORE combination, and Windows loads normally, I load up AI Booster, ASUS PC Probe II, and CPU-Z. Now, ignoring the fact that the new BIOS version (1503) makes my readings 15 MHz lower for the FSB, why is the voltage displayed by CPU-Z never as much as the 1.625V that I set in the BIOS?<br><br>
- Relating to the previous question, which options in the BIOS do I need to have enabled/disabled in order to disable EIST and C1E? Right now, everything in the chipset configuration menu is disabled except Microcode Updation. Summary of what I have set:<br>
Ratio Unlock: Disabled<br>
Microcode Updation: Enabled<br>
Max CPUID Value Limit: Disabled<br>
Execute Disable Function: Disabled<br>
CPU Internal Thermal Control: Disabled<br>
Is this correct?<br><br>
- I would like to use Prime95 to load my computer to test the OC settings stability, but it won't let me load more than one occurance, so my dual core processor is stuck at 50% usage only. Anyone know how to get around this?<br><br>
- For the OC Profile, does it need to be stored on a floppy? It would be easier for me to have it stored on the HDD or a USB drive, but I am not sure how.<br><br>
- What are some stable OC settings that you all have achieved with a Pentium D 930, and were they on air, water, or phase? Any OC profile file that you could give me would be nice as well... <img alt="" class="inlineimg" src="/images/smilies/tongue.gif" style="border:0px solid;" title="Stick out tounge caps"><br><br>
Thanks in advance!

Someone has to be able to answer one or two of these questions...

Ok, as for the vCore in bios, don't worry about it unless the bios vCore is absurdly lower compared to your ai booster readings. In your case, it is the opposite, you are setting 1.625v in the bios, but due to the vDroop of the motherboard it lowers the voltage consistently by a little bit. That's why you never see 1.625v in AI booster when you set it to that value in the bios.<br />
<br />
now for your other questions:<br />
<br />
-the only things I would enable are microcode updation and execute disable bit, which protects your pc from hardware attacks from viruses.<br />
<br />
-Make two different folders of Prime95, launch both instances, set one of them to work on cpu 0 and the other to cpu 1, then manually assign about 40% of your remaining RAM to each Prime95, then run them both.<br />
<br />
-Or you could simply get orthos, you can google for it.<br />
<br />
-You don't need a floppy for OC profile<br />
<br />
-On the topic of oc settings, every machine is different, so you'll have to test and experiment with your own settings. Finding your max OC is a very slow process.<br />
<br />
Good luck and happy Overclocking.

It's a trial and error process. Adjusting settings in the BIOS is better than AI Booster (the same OC Profiles that AI Booster uses are in the Bios also.) But if you do perform things manually, adjust one setting at a time - this way if something doesn't work, youll know right away what you changed that caused the issue.

I can answer one <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />,<br />
"why is the voltage displayed by CPU-Z never as much as the 1.625V that I set in the BIOS?"<br />
<br />
Most if not all Asus motherboards are notorious for a Vdroop, a fluctuation in voltage set from BIOS and what is actually the true value. I wouldn't worry if the Vdroop is less than .05V.<br />
My P5B Deluxe also has a Vdroop, I set BIOS Vcore to 1.3825V but CPU-Z reads 1.344V (~.04Vdroop).

I just realized that I said 1.625V. Haha, that would make for one fried chip! I meant 1.265 I think. Anyway... My vdroop is about 0.06V at worst. Is that too far past the 0.05V threshold?

I have the droop problem too. I select 1.425v in BIOS but CPU-z displays 1.376v<br />
<br />
So is the selected BIOS voltage the 'true' voltage?

My voltage also hops around - it doesn't stay at a specific number.
