Anyone running 4gb of Corsair 3500LLPRO on an ASUS A8N32SLI

[GnomeCop]

Are there any issues with installing 4GB (4x1GB) of Corsair 3500LL pro memory in an ASUS A8N32 SLI board?

Are there any settings I should look out for? do I have to change the command rate to 2T or something?
I will be using win XP Pro 64

4GB!!!! Thats A LOT!

You would have to decrease the command rate to 2T in order for 4gb to work. IMO 2GB (2x1GB) is more than enough for now.

I wouldnt actually go out and buy 4gb.. thats crazy
but I already have 2gb of this memory and I may be getting 2GB more for free, so I guess why not toss it all in and run it.

if ur using win 64.. its good.. i got 6 and when i go ddr2, those old ddr memory are going to i-ram drive..

hmm got it all installed and only 3gb registers... its set to 2t cmd rate and I am running windows x64...
what else could it be?

Use the bios Luke!

I've read of cases where the BIOS will only see 3gb, but if you boot into Windows, you will see all of the ram.

hmm the bios reads 4gb installed, 3gb useable...
windows sees 3gb only...
gonna have to mess around with the bios further I guess

Got it! Found the correct settings in the bios.

Advanced - CPU Configuration (Make sure on this page MTRR Mapping is set to Continuous) -
Memory Setting - Memory Configuration - "Enable" the Hardware Memory Hole. (this was the one I kept overlooking)

Reads 3.89GB Ram on My Computer Properties (Discrete), and 4.0GB (Continous MTRR Mapping)
Reads Usable Mem 3.37GB from msinfo32 (Discrete), and 3.48GB (Continuous)

BIOS reads on boot up "3984 ok (Installed Mem 104" setting on (Discrete), and "4096 ok (Installed Mem 104" setting on (Continuous)


now bios detects all 4gbs correctly and windows x64 detects 4gbs too. Took out the /PAE switch in boot.ini since I dont think it was doing anything.
