Asus P5QL Pro & 8 GB RAM

Posted on 2009-12-16

I just upgraded to Win 7 Proffesional 64 bit, I have four 2 Gb Ram sticks A-Data DDR2 800 MHz
And an Asus P5QL Pro motherboard with a P4 D930
I can run with 2x2GB stick NOT in dual chanel mode. If I put one or two more sticks Win will freeze, 3 or 4 GB, It will look as if its trying to load but will take ages an nothing will happen.  If I take out the extra memrory and stay with 4 GB the system will start with no problems.
I do not understand the BIOS settings so most of them are set to Auto, default.
I know the memory is not on the Asus list, but that hasn't been a problem with previous Asus Motherboards.
I havent tested the 4 GB in Dual Chanel.
I have updated Win 7 and used the 64 bit chipset drivers from Asus and also the nvidia video drivers.

Any ideas?

    Accepted Solution

    As with most Asus P5xxx boards it's simply an unstable erratic platform in general.
    With 221 reviews in 25% rated it poor or very poor.
    Most of the Asus P5xxx boards are similar.

    If the RAM isn't on Asus's compatibility list you are virtually guaranteed to have RAM problems with those boards.

    Many motherboards with that chipset have issues with 4x2gb memory configs as it puts slot of stress on the bus the usual work around is to relax the memory timings and up the memory voltage.

    Thanks guys.
    I've started to play with timings and voltage, so far no luck.
    Both of the comments are correct, there's no direct answer but to play or give it up.

    Happy holydays
