3.3v rail voltage drop

[Blip]

On my 520W powerstream the 3.3v rail keeps dropping. Maxed out it is now down to 3.31 v(green light) when I first installed the PS with no adjustments it was 3.328v . I noticed it when my system became unstable and the 3.3v rail was down to 3.1v. I adjusted it back up to 3.328v but that was max before the light turned red. Today it is down 3.31 maxed and the other rails are now starting to show variations in voltages aswell, but still within spec. I am using ASUS Probe to monitor my system.
P4C800-E (1016 BIOS),3.2C , XFX 6800GT ,KHX pc4000/1G, Im using intel RAID0 2XRaptors (my Promise SX4 RAID5 controler is out for RMA RAID5 3XRaptors) Raptors=36G.
I have also had to drop my clock speed down to 3.89Ghz from 4.0Ghz, 243 down from 250 FSB.
System hardware and software is unchanged so I can only assume the ASUS Probe reading are consistant. BIOS is also showing the variations in voltages

Well first off the Asus probe software and the bios on the p4c800's read the 3.3V rail to low. On mine if I want to have it showing 3.3V or more in the bios/mbm 5 I need to crank the pot until the LED goes red. Then with mbm5 showing something like 3.31V my DMM will show 3.44V. So I wouldn't trust the bios or any programs for that.

When you say you had to drop your clocks down are you thinking that was from the 3.3V line or something else? Did you have to drop it after installing the video card or was it always in there?

Yes I understand ASUS probe and BIOS do not give accurate readings. All I was saying is that before I had not changed a thing and my comp was very stable. The voltages were stable the bios and ASUS probe, when I started getting instabilaties and noticed that ASUS prob and the BIOS show a voltage drop. I adjusted the voltages( first adjustments I had to make to PS) to get the voltages back up to where they were and to get the stability back, but to get back to stable comp and indicated voltages to what they were the 3.3 v rail is now maxed out. All things being equal I do not have the ability to bump it up any higher then what it was before I had done any adjustments on the PS. So now if what you are saying is that because they read low I am now running lower then the 3.3v with the PS maxed out on the 3.3v rail ?

[SteveOCZ]

No your 3.3V rail shouldn't be maxed out. When you said you adjusted it did you crank it all the way until the pot stopped?

Anyways I will RMA the unit for you if you like. Then you can be sure it is in the best working condition. If you want to do that just sent me an email with a link to this thread and I will get you started

No I did not turn it all the way, just till the LED turned red. Then I backed it off until LED turn green. Im sorry I should have specified that before. I only assumed that RED was getting out of spec. I can live with 3.89Ghz and if all stays as is Im happy even though my benchmark scores have dropped down :3Dk2k1se 23,361: 3DM2k3 13,761 :3DM2K5 5291 : Aquamark 74,776
