This is my very first post on this forum so - hello everyone!
I'm trying to get to grips with RAM testing. I have 2 x 512MB sticks in my PC, one of which is brand new and the other is a year old. I'm using Crucial CT6464Z335 on an Asus P4S333 mobo running Award BIOS revision 1007C. I recently ran a variety of RAM-testing utilities and got a mixed bag of results. My memory failed the WStride-6 test in Windows Memory Diagnostic (WMD) and also failed the Modulo20 test in MemTest86+. The memory passed MemScope and MemTest (HCI). BTW, I'm testing both sticks of RAM simultaneously.
Clearly, the different utilities use different algorithms, which is no doubt why my memory passes with some utilities but fails with others. Although my PC appears to be running without any problems, I'd feel more comfortable if the memory passed the WStride-6 test and Modulo20 test. I've checked the BIOS memory settings and it is set to [By SPD].
So, I have some questions. Is it possible that the failures are caused by the cache rather than the RAM itself? Are the WStride-6 and Modulo20 tests unrealistic?
Any suggestions would be greatly appreciated.
