Well Im fed up with this the vcore drop is HORRIBLE. I put it at 1.6V goes down to 1.52 and bounces around. Options:<br><br>
1. Buy a P5WD2 Premium and see if it doesnt drop as bad<br><br>
2. Any simple mods?

I know of a dangerous mod for the P5W Deluxe which I did and it helps but only to 1.63. After that vDroops like nuts with a max of 1.64 at 1.70 ...grrrrr...

I'd get a P5W DH or a P5B and a conroe - the vdroop is bad on the boards I tried with my d930, but is almost non-existant with the e6600...

</div>Not an attack on your statement, but.....<br />
<br />
I don't think so....Most P5B Deluxes will droop .06-.07 Volts at settings over 1.6 Volts...at least all the ones that I have played with do....ask Sdumper...he knows too....<br />
<br />
Please don't take offense to this...

</div>None taken <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /> I never got to use the P5B as it dies during flashing, and when the new p5w dh bios came out there was simply no need for it...The P5W DH didn't droop more than 0.01v for me with 1.65, but that was as high as I dared go.

</div>I have 2 - P5w DH Deluxe mobos and the vDroop is better than on the P5B Deluxe BUT it does exist and will max out at 1.65 even on 1.7. My recorded vDroop on 1.65 on both boards the 67MOAG and the revised 68MOAG is not as good as you described. 1.65 actual measured at the contact terminal is 1.63 and measured by the op system is 1.62 to 1.63 fluctuating with spikes hitting 1.64 for very short durations. You can compensate for this somewhat by bypassing AS3366 capictor bridging pins 13 and 14. It was a tip Muffin gave me and it does help but is not perfect and only works below 1.65.<br />

If you want rock solid vCore and you have the appropriate cooling to match then consider upgrading to the server boards or try the new abit board. If you opt for the abit board wait until ThaWaxShop finishes his testing and review to make sure it actually delivers as promissed <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" />

I was going to post a new thread about vcore, but I guess I could ask here - What's a reasonably safe vcore threshold for the P5W delux and E6600?

</div>Depends on your cooling...if you’re on vapor/phase cooling and your operating at temperatures well below freezing you can go as high as 1.8 for benching and 1.65 to 1.7 for 24x7 operations. If you are running anything above freezing then it is not a simple answer because different CPU's have different rated tolerance levels.<br />
<br />
For Allendale/Conroe chips the throttle temp is 85c. The thermal tolerance specs state it should be operated in the 61c level. All of that said I would maintain a max vCore at a level that takes you no higher than 75% of your throttle level which comes out to roughly 63c. I would also not add vCore under any non subzero cooling higher than 1.62 (actual no vDroop) for purposes of benching. For everyday operation I would not exceed 1.55 vCore. <br />
<br />
Keep in mind that at higher temps and vCore voltage migration will occur. After a period of time migration will produce voltage channels that will permanently deviate from the designed paths and eventually damage the chip beyond its ability to function.<br />
<br />
<br />
So quick numbers: vCore of 1.55 and temps below 63c should be fine for 24x7 operations. vCore up to 1.62 and temps below 70c should be fine for benching (short duration).<br />
<br />
All temps: are TAT
