4 GB on P5N32E SLI

[Animalmom]

IS there a problem with runnign 4 GB of ram on a p5n32E SLI?

I was having serious instability problems - I pulled out 2 sticks and now have 2 GB and it runs fine - swapped the 2 and it still runs fine so I don't think its a memory failure.

Someone mentioned they heard that there is a problem when using all four slots on this board - is there anything I should know?

That is a loaded system. Have you ever gone into the bios and checked to see what the voltage rails are reading? Are they within a 10% tolerance? Have you tried upping your ddr2 voltage? Have you installed one stick at a time and run memtest86 to see if you have a possible bad stick? Sometimes motherboards can be picky about certain brands of ram. And using 4 GB can be hit and miss as well.

Thanks - The voltages are 1.875v on auto which is lower than the 2.0-2.1 they are rated for (muskin). When I manually set them to 2.0 the system is even more unstable.

I have not used 1 stick at a time I suppose I should try.

Thanks.

Try the Mushkin at 2.1. Their memory loves voltage, and you wont hurt it. Worth a try.
In fact, I set mine to 2.1 before I even booted with it.

will do thanks

Im running with 4g ram on that same board and have no problems with it.
But i noticed when i bought it, there was a sticker saying, and i quote

"Due to NVIDIA nForce680i SLI chipset, ASUS only guarantees DIMMs on memory QVL(Qualified Vendor List).
Other DIMMs might cause system instabillity."

Maybe thats what you are experiencing ?
