Running great on 2 sticks, bsod on 4


Arctirus

Recommended Posts

I've got an asus P5N32-SLI SE Deluxe running the latest bios that has been running fine with a 20% OC for months on two 1 gb sticks of xms on winxp x32. I put two more 1 gb sticks of xms in it in anticipation of my vista x64 upgrade. Xp became unstable, occasionally bluescreening at random. This was solved by going to normal clock speeds.

 

So I then attempted to install vista x64. Even at normal clock speeds vista was flaky at best. I realized that the memory I started with was the epp 4-4-4-12 stuff and the new memory was 5-5-5-12. Being as that I'm about to build an additional system anyway I thought I may as well save the 5-5-5-12 stuff for the new system and buy another 2 gb of epp for this one.

 

That's when my problems really started. Vista acted very flaky when I put the two new dimms in. I know I "shouldn't" have to reinstall an os for a ram upgrade but it was worth a shot to see if it would fix my problems. I could not even successfully install vista with the four 1 gb sticks of epp on the board. I took them out again for the install which then ran smoothly. I put them back in afterwards and although no bsods vista runs VERY slow. For instance the little green bar that scrolls during boot makes more than 50 passes before I finally get to a logon prompt.

 

I looked at the below thread for advice, I tried all throughout this process various combinations of enabling and disabling memory mapping, setting timings to manual or auto etc. The board in this thread is slightly different than mine though, 680i vs. nforce sli 16x, so I haven't found anything on my board about LDT frequency.

Any advice to get this working?

Ok, I attempted to change the changing the frequency 667 and there isn't an option to do so. When I set the timings to manual it looks like there should be an option that lets me change, however when select it and hit enter nothing happens. I even tried setting the timings to 5-5-5-12, it wouldn't even boot. At this point I don't even care about getting the extra speed, I just want a system that will boot properly with four sticks.

The setting to change the memory frequency is on the first image you gave me.

Please look at your manual in section 4 for how to make that change.

You can use these settings for reference:

SLi ready: Disabled

Memory Voltage: 2.0v

NB Core Voltage: 1.4v

TCL: 5

TRCD: 5

TRP: 5

TRAS: 15

Command Per Clock: 2

TRC: 28
