Iwill XP333-R 2nd Memory Chip Gives 3DMark Lockups&Crashes but not in another identical system?

I have an Athlon XP 1600 and 2 256 meg DDR chips (same type), and an Iwill XP333-R Motherboard

For some reason, the second chip was causing 3dmark and games and such to become unstable.

It did boot into windows just fine.

When I take the memory module out, the system runs perfect, 3Dmark 2001se completes and gives an excellent score.

When I put the same memory module into a friends system with his memory module (he has the same motherboard too), and everything (except he only has 256 megs in the first slot and it's OCZ 333 mhz memory) his system boots and runs 3DMark 2001se just fine

I take it out of his system, put it back into mine, and it starts locking up and crashing games and such again. (especially 3dmark 2001se)

To me, it sounds like a slot problem (the memory voltage, settings are all the same in both systems as to minimize any inconsistances, the fact that it works in his system is very puzzling).

The only problem with the slot idea that i see, is that it has to be a freak accident. Cause we put the same module in the same slot on his board and he has the same board, same bios, all that.

If thats the case, could putting the second module into the 3rd slot work? (I also looked to see if the board supported table free memory which should allow me to put any module anyone, even if the middle slot is empty but I couldn't find out if it did, from my few installations, i would guess not) I tried that in his system, but it didnt boot, I remember also that when I first put the computer together, I put the modules into the 2nd and 3rd slots (none in the first), and it didnt' boot for my system either.

If I can't put it in the 3rd, and for some reason it is the second slot on my system (i checked the layout of the slot, looks clean to me), then I can't get more than 256 megs of ram in the system unless i buy a 512 :(

Well, anyway, any ideas would be great, I dont know what else I can do other than stick with the 256 megs of ram (which, at this point, would be just fine, I just want a decent stable system :))

Thnx anyone!

The ram slots in my XP333-R are VERY tight. I initially had trouble POSTing with one stick, both sticks would actually lock into place, but weren't seating fully. After deciding to just go for it after reading some posts about the slots, I really jammed 'em in there and a loud click verified that they were finally, fully seated. Even the chip that would POST and run well was not fully seated at first. Not a single problem since.

Do you guys have the same bios? If so, you may want to pull out WPCREDIT and try changing data 78 to either C0 or 80, one should give you problems, other should be fine..

I'm using the 1/18/02 bios.

We both have the same bios yes.

Maybe I'll try reseating them again

It didn't seem to hard to get it in, and i've already moved it a few times with the same results, but one more try can't hurt ;)

I'm just thinking i'll be stuck with the first slot... unless I can use the 3rd as well (if the second slot is indeed the problem)

Mine weren't hard to get in and lock, they LOOKED correct, but weren't fully seated. They were hard to seat though, firm pressure until it gave a loud click, literally flexing the MB to do it <-- somewhat scarry:Q:p

actually, try more than just bank 1 & 3 as a combination...try 2 & 3 as well...sometimes some boards are bank-picky...it's odd. (bank 1 = bank 0)

try this as well to determine whether or not it's that specific module (though u did already try it in your friend's board)...swap the module in bank 1 w/ the one in bank 2 adn run them both...if you get the same problem, it's most likely picky about having them in bank 1 and 2 together...

your board will most definitely support modules in ONLY bank 2 & 3 or bank 1 & 3, so try those combinations and see how it turns out...

to get both modules working if it doesn't in the above circumstances, u might have to adjust the memory timings more conservatively...it's a known fact that memory stability decreases with more modules...the signal weakens.
