ram problems :/

[Spud1]

Ok i have just bought a 512 meg stick of PC2700 DDR ram from crucial, and i stuck it in my PC along with another 512 stick of PC2700 DDR - the only difference between the two is that one is from crucial, and one is by PCA. They are both Cas 2.5, have the same number of chips, are none eec etc etc

My problem is that with both sticks in my PC crashes all the time with a BSOD, and it varies as to which i get. the most common two are the

PAGE_FAULT_IN_NONPAGED_AREA

and

STOP:0x0000008E (0x0000005,0x00594D32,0xED3A3B64,0x000000)


Both of these are what i used to get when i tried to overclock my old PC2100 memory too far, but now this is happening with my brand new PC2700 memory, and it is not overclocked at all - everything on my PC is running at stock speeds atm and it still happens

I've had to take out one of the sticks to use the PC until i can find a fix :/

It seems to point to an incompatability between the sticks since the PC works fine with just one stick, but i thought that if the sticks were not compatable then the PC would just not boot...

Anyway ive tried all combinations possible with my mem slots but still no joy, i've even tried reducing the memory bus speeds and cas speed etc but it had no effect.

Cam anyone offer any advice? as i think i have just wasted £70 on a stick of crucial ram

Oh and i just had a thought, could this be a power issue?

So both sticks work fine on their own but not together?
Many sticks of RAM simply don't like each other unfortunately.
Crucial should give you a refund for that stick mate they're usually pretty good like that!

i just looked on teh crucial site and i think your right, so i'll go for a full refund i rekon; i thought it must be that they dont get on with each other, but just wanted a 2nd opionion

unlucky :/ im guessing you've tried all the combinations you can think of with your ram slots....

What mobo ?

Also have you run memtest on each of the sticks ?

[Spud1]

the mobo is an MSI K7 delta ILSR nforce2, and yeah i've checked both with memtest, both work fine on their own so the only conclusion i can come to is that they are not compatable

[Trickle]

Would be nice to try both 2700 sticks in another board, but tbh I'ed just rma them. This is assuming your MSI board has already been tested with 2X sticks in the past?

i've even tried reducing the memory bus speeds and cas speed etc but it had no effect.

I'm assuming this means you have lowered the other mem timings, not just cas?

[Spud1]

well good news here ;D

all working now

crucial just told me to increase my VCache to double the amount of ram in my PC

and for some reason it now works flawlessly...i cant work out why the Vcache would have any effect but it has, good ol' crucial

thx for all ya input tho
