ASUS P4PE/RAM problem

Hi everyone

I have a P4 2.53 Ghz, 300W PSU(this might also be the source of my problem), 512 mb DDR333 RAM, ATI Radeon 9800 PRO, Windows XP PRO, and ASUS P4PE (obviously )

Recently I have bought another stick of the exact RAM, so now I have 1 GB. Problem is with the GB of RAM my computer constantly crashes, can't run any games for more than 2 min without it closing and getting a general error. On numerous occations Windows has froze on me, and other times the computer rebooted itself. Obviously I can't work/play like this, so I tried messing around to see what the problem is, and obviously i havent figured it out, but here's some info on what I've tried and the outcome.

I know the mobo supports everything.
Both sticks work individually, but not together.
Tried switched the slots they were in, nothing.
Made sure they were getting 2.5V in the BIOS.
I turned down the speed to 266 and is working perfectly (it's running on it as I type)
I would have tried updating the BIOS but www.asus.com is down.


Thanx for your help guys.

Getting frustrated and annoyed,
Dagonal

my first guess was crappy ram cause my brother bought generic ram and it made his computer do the same thing until i replaced it with corsair ram.but then you said they work seperately but not together which would be prolly a type of combatibility error but then you lowered the speed to 266 and they work fine??? my only guess would be compatibility between the ram and mobo or something

sorry if i couldnt help you

Have you tried upping the Vdimm voltage?

It should be compatible, they're the exact stick of RAM, Samsung 512mb 184pin PC2700(333), not exactly the cheapest, but not the best.

I haven't tried upping it, it's suppposed to run at 2.5V, so I didn't want to cause any harm.

Download and run memtest on with each stick, to be sure there are no errors. (Just because they boot doesn't mean there are no errors.) Do you have monitoring software to check that the 2.5v set in BIOS is actually delivering 2.5v to the slots? And try upping Vdimm at least temporarily. It won't cause any immediate harm. (It can eventually reduce the life of the ram, but bumping up .1 or .2v temporarily won't hurt anything).
