Hi, everyone,

So I'm currently running the following O/C

C2D E7400 @ 3.4 GHZ v. 1.3125 (8.5*400)

I've was told that a quick way to test lower voltages was to use Intel Burntest. Doing this, I tested the following:

1.31875
1.3125
1.3000
1.29375

IBT reported all stable after 10 passes. (Max temp reached in one instance was 70C), but on the last, 1.29, I noticed some odd W7 behaviour. From the W7 Welcome Screen to the Login Screen, there was now a delay, where there would be black screen before the Login Splash. Prior to this lowest voltage setting, it used to be Windows 7 to Login very quickly. I chalked this up to instability.

Since, I'm back up to 1.3125, and ran Prime95 on Blend for 10 hours (56C maxed), and everything seems stable.

What would cause this apparent delay of the Login Screen? Is this something I should worry about. I noticed that moving to 1.3125 voltage that this apparent delay seems to be lessened. Should I up the voltage a little more?

Advice?
Thanks for the help.

If you set it back to stock settings, do you still get the delay? Could you also list what you have your RAM set to?

A root kit loading before windows could also be causing the delay.

Hi,

Yeah, RAM is all default settings of the RAM. 1.8v 5-5-5-18. PC6400 DDR2 800 Mhz.

Ran Memtest, no problems. At 1.3125 stable and no longer does that delay happen.

So does that mean it was software, and that I could lower my voltage safely again. Or should I leave everythting as is now on my Asus P5Q Pro?

Thanks!

I would leave the voltage as is, not really going to gain much by trying to under volt the OC.
