I bought this RAM from Newegg and have had nothing but problems with it on my K8NS Ultra 939.
Here is what I can do:
I can simultaneously run Prime + memtest 9 hours stable (on my 3000+ winny) with BIOS set to 133 (160MHz effective speed) @ RAM stock default 2-3-3-6 settings. The bus was set at 250x9 perfectly stable. I can raise the bus further while maintaining stability, but I really don't care for the extra speed.
Here is what I can't do:
I cannot run the CPU at default speed using BIOS default settings at any CAS setting whatsoever with the RAM, including 3-4-4-8. To translate, the CPU default 200MHz speed/bus is unstable. I get blue screens/registry hive errors, etc.
Any attempt at running this RAM at 200MHz results in Prime failing within 1 minute (usually instantly) and memtest finding errors even before starting. I can return stability by setting the RAM to 193MHz (and underclocking my CPU) using bios settings. At 193MHz it is only Prime95 stable for ~1 hour max, but memtest will fail within 20 minutes. This occurs in Single- or Dual-channel modes. I left memtest on for 5 minutes and there were over 100 errors.
What do you guys think? A friend of mine also ordered this RAM from Newegg, and while his IS stable at default speeds, it cannot post over 218MHz at 1:1 with any amount of voltage or CAS settings.
I personally just want 200MHz stable operation. Anything more is just headroom to me.
Am I wrong in assuming that this is a RAM problem? I am kind of bummed because I am at week 6 of RMA'ing motherboards and now RAM. Looks like I am going to await another 3 weeks to ship from NY to CA to NY again.
