2 Gigs Ram Upgrade Crashes PC

I've been under gig of ram for too damn long, and when I finally got my upgrade to some nice 1 x 1gb dual channel memory, it just WON'T WORK!

So here's the deal. I installed them immediately upon arrival and windows would not completely boot. So I took one out, and left the other one in, everything works fine. Testing the other stick, works fine. But whenever the two sticks are together, whether in dual channel slots or not, it DOESN'T WORK. I can't even install a fresh copy of windows or ubuntu.

So any ideas? After some research I was thinking the power supply, but I'm not an expert tech or anything. The computer is 5-6 years old now, it only has a 400W power supply for a Pentium 4 CPU... I just don't know if a lack of power could cause this. Come to think about it, could I test for that by removing a lot of my extra components? Or it is based off what the motherboard is getting?

Like I said I am not a tech expert when it comes to power. I remember way back when I thought messing with the voltage options would be cool... not cool...

What mother board is in there? Did you read the specifications for it before you bought the memory? Sometimes the memory sticks can't be that large and with all mother boards there is a limit as to how much it can take. That's why you have to know what mother board is there.

Double Checked It I am pretty sure, but just in case you want to look

Albatron PX865PE Pro II

google search link for you

The memory is G-Skill, PC3200 (400mhz) Dual Channel 2 x 1 Gig

Motherboard should support 4 GB as reading the specs claim. And I am only putting in 2 gigs. So I believe that aspect should be good.

On another note, I unpluged my extra cd-rom and extra HD, still getting the same problem. But then again, I think my windows install cd is screwed, going to have to get another copy from the school. Going to install the old harddrive with windows on it again and try to boot with a installation in place. I suppose I could of mentioned that I am trying to format the new 500Gb hard drive I got for it too. Hmmmmm. Still messing with it.

4 * DDR Sockets:
DDR400/333/DDR266 NON-ECC DDR SDRAM up to 4GB
Note 1: If the FSB of your CPU is 400 MHz, the memory speed supports only DDR 266.
Note 2: If the FSB of your CPU is 533 MHz, the memory speed supports DDR 266/333
Note 3: If the FSB of y

Read notes 1 and 2. Three looks like it was lost somewhere.

Sounds like the motherbored is not able to handle the amount of ram.

The CPU FSB is 800 Mhz. The motherboard recognizes the 2 gigs at 400 mhz, but windows crashes. but I do believe its hardware related. and like I said, each stick works individually

have you tryed running one at a time in each slot?

You mean like testing the slots individually for a defective slot?

I initially had two sticks in dimm 1 and 2. and the gigs don't work when in 1 and 2.

lol, I just got a crash with a single stick,but it at least booted into windows...

yes test the slots individually with each stick

For instance
Test all your slots with one of the sticks and then do the same with the other.

Also, if there are 4 slots, use 1 and 3 or 2 and 4.

OK, here we go. As I mentioned before I don't have good experience with voltage. I looked at the memory specs again, I got them from newegg ( heaven for computers parts ).

Check it out

The voltage sys 2.6v - 2.75v on the specs, and my motherboard is set for 2.55v, now can I assume I am allowed to increase the voltage then? lol, bad memories come back, but it seems reasonable... and if so, what should I increase too.. 2.65 or 2.75?[/url]

Either way, I shouldn't have to do dual channel if I don't want it, I initially tried on 1,3 and 2,4 and tried other combinations in case there was a problem with it being dual channel itself.

Ok, then I'm out of ideas. Good luck with it.

The voltage thing doesn't seem to make a difference. windows crashes right before the welcome screen. just reboots itself.

Running MemTest 86, found 3 errors so far. I think I will just be sending it back.

however, memtest on each individually reveals no errors..
