Re: D975XBX2 + 8 GB RAM = unstable :-(

Curious, have you tried any other 64-bit OS on it, to see if the same
issue occurs?

Hi Yousuf,

No. But that won't really help as I need Vista64 to do what I'm trying to do.

I'll run a memtest program on the 4 pieces of 2gb (2 at a time) to be sure it's
really not the RAM. But since Kingston RAM tanked as well in the same setup I
don't think it's the RAM.

In reading the manual for the Asus 975X chipset version of this board (P5W) it
states:

"You may install a maximum of 2 GB DIMMs on each slot, but only DDR2-533 2 GB
density modules are available for this configuration"

While the Intel manual states:

"Support for: Unbuffered, non-registered single or double-sided DIMMs
ECC and non-ECC DDR2 800/667/533 MHz memory
Serial Presence Detect (SPD) memory only
Memory configuration listed below:
· Up to 2.0 GB utilizing 256 Mb technology
· Up to 4.0 GB utilizing 512 Mb or 1 Gb technology
*****Up to 8.0 GB utilizing 1 Gb technology***** "

This last line is curious in that it suggests that only "1 Gb" pieces will work
on the 4 provided slots... Hmm..

Meanwhile recent chipset boards from Asus like theP5E (x38 chipset) offer a
"Memory Remap Feature" (for 64bit OS's) in the bios where the Intel boards with
this same chipset do not.

I assume within a year 8GB RAM will be very commonplace (wait for the next
version of Photoshop to hit the shelves!). But for now it's apparently still
uncharted territory where folks like me find out the $$ hard way what promised
(but untested) features are just not there ...
