P4PE and Ram issues.

[Stallion]

I have a Asus P4pe wit ha 1.8A that I run at 2.5+ I have one stick of Corsir XMS 3200 which is set at 373mhz in my bios. Well all has been great for the past while with no problems ,until today.

I bought another stick of the same and a new video card( which has it's own issues as well, please feel free to visit my post about that POS in the video forums if you would like) so I could get the most from Doom3.

Well for some reason my systems didn't like the extra ram and upon boot up it sent me to the bios and mentioned something about the speed. I just pulled the ram out and tried to at least get my video problems worked out.

question is. I guess the board only supports 2700/2100 at a 533fsb and 2100/1600 at 400fsb but mine has run great at 560fsb (140 in the bios) until I added another stick.

do I need to go back to a 100mhz speed to get this thing to accept the RAM and then set it back up once it's running? Will I just not be able to OC my rig now.

Am I missing something?

I think you should reduce the overclock rate until you can boot properly.
Then, run memtest. If you pass, increase the overclock rate slightly (2MHz FSB increase) and test again. Keep doing this until you find the maximum stable rate. Hopefully, it will be a few MHz below where you were before.
I have read reports that systems are more stable with only one stick of RAM.
So, this makes sense if you are the max. overclock rate with one stick, you will need to reduce the overclock a little bit to go to two sticks.

I had that board, and overclocking with more than 1 stick of ram was a PITA. Up the vDIMM, set conservative timings, try them in different combos of slots, and good luck. That board really made me understand why Asus isn't elite anymore, I and others have had trouble with it using power hungry 8x AGP cards too.

Well I took my PC to a guy( Russ) that does all my stuff that I can't do to see if he could fix my video card problems. Don't know if you know Russ, he posts here.

Anyways ,he got both sticks of ram to work together but he had to drop my FSB down to 120 and anything over that and it wouldn't work.

So I guess it's either a 1.8 @ 2.5 with 512 ram or a 1.8 @ 2.1 with 1G ram...
