n00b here w/ Strange Problem

[hypnotichouse]

hey there AnandTech friends.. maybe some1 wiser than I can help me with my problemo..

heres the deal.. I, like many others, thought the Pentium D 805 was an awesome deal. It's cheap and overclocks well. Being my first Overclocking experiment I thought this would be a good idea.

So i went ahead and bought:

-Pentium D 805
-Asus P5WD2 Premium
-1GB(2x512) Corsair XMS2 DDR2 675
-Thermaltake Bigwater 745

I alread had:

-Antec TruePower 2.0 480watt PSU
-eVGA Nvidia7800GT pci-e
-3 SATA HDDs
-2 DVD burners

I built the whole system and it ran fine. I followed the guide on this website and overclocked my system to 3.6Ghz any more and it would power on right. I guessed this was because I was only running a 480watt PSU.

This was fine but I really wanted bigger and faster so I bought a new PSU and Video Cards and rebuilt again.
This is my current system:

-OCZ Gamestream 600W
-Pentium D 805
-Asus P5WD2 Premium
-1GB(2x512) Corsair XMS2 DDR2 675
-Sapphire ati x1900xtx
-Thermaltake Bigwater 745
-3 SATA HDDs
-2 DVD burners

I now run this current configuration at the stock 2.66Ghz, but would like the 3.6Ghz or higher. The REAL problemo is when I touch any of the manual overclocking settings in my BIOS. If I even change the Frequency from 133 to 150 my computer will not boot properly. It turns on but has no video and has a crazy beeping pattern beep-beep-beep-beep-beep, beep, beep. I use Asus' CPR feature to reset my bios when this happens. I have tried overvolting and undervolting and no matter what nothing works with any manual overclock settings. AHH! the only way it boots is if everything is set to Auto.

I was thinking that maybe the x1900xtx has something to do with it. I believe 600w psu is enough. after all i was using a 480w psu and pushing it to 3.6Ghz.

Anybody out there with a familiar issue or have some tips? I'll try anything reasonable. lol. Thx.

Yeap. You can set that in the Bios. I guess I better get familiar myself with Intel boards.

I'll try it out in a bit and report the results.. any reason why this happened with the x1900xtx and not the 7800GT?

ur mobo may be the problem...

oooof.. i dont like to hear that.

by fixed frequency did you mean manually set it to 100Mhz. i tried that, but still no luck. i'm going to dig around a bit for more pci-e frequency help. that may be the right track. i dont know.

well i don't think my mobo is the issue because it works fine when not touching the overclock settings in bios

tried setting pci-e frequency from 100-115 and no luck.. i did some reading and keep hearing people mention Asus PEG setting. could this be cutting out my video on my x1900xtx with i'm overclocking CPU?
