I just stumbled across a problem with an A7N8X I bought for work. So, excuse me while I post first and read the rest of this thread later.
Components are:
Asus A7N8X Deluxe
AMD Athlon XP 2100+ (running at 133MHz DDR)
Three Kingston 512MB PC2700 DIMMs (running at 166MHz DDR)
Chaintech GeForce4 Ti4200 8X AGP card Blah, blah, blah ...
With RedHat 7.3 installed and finally configured for nForce2 devices (IDE, sound, USB2, dual NICs, etc.), I've noticed that the system locks up on occasion. The Scroll Lock & Caps Lock indicators flash simultaneously. I first noticed something strange when only two of the three DIMMS was recognized via BIOS.
I booted the system with my MemTest 3.0 CD and have let the test run through a few times. With just one stick in the system, MemTest reported no errors and RedHat runs fine. With two or three sticks installed, MemTest shows errors in the last 0.3MB of the address space (errors at 1535.7MB out of 1536MB installed; same thing with 1024MB in the system). I haven't finished testing all sticks individually, but with the various swapping I've done, no single stick seems to be problematic.
I've started scouring the 'net for clues, but I haven't found anything yet. I'll muck around with the memory settings to see if the asynchronous timing causes problems as well (133MHz CPU + 166MHz RAM). Maybe I'll let the system run entirely at 133MHz over the weekend.
I forgot to mention that I have two other systems that are nearly identical to the A7N8X system. I have the MSI K7N2-L motherboard (still nForce2 chipset) in these systems instead of the Asus. RedHat's been solid on these boxes, so I haven't had the need to run MemTest on them. 1.5GB RAM and fine.
Any insights?
-SUO, going back to read this thread now
