My workhorse Epoxy 8K3A+ (KT333 chipset) has 1 stick of XMS3200 Cas2.5 512Mb Corsair ram in slot 1.
The Ram and the system bus are running synchronously at 167Mhz.
When i first got the mobo and ram, I found something curious with Memory timings: Turbo memory timings were fine at stock voltage up to around 170fsb, but in order to run 1T command rate required 2.6V or better. Even down at 133Mhz.
Stability was determined by multiple MEMTEST86 passes.
Fastfoward a number of months to last week, when my system started displaying unusual buggy
behavior and the odd BSOD.
Initially i thought it was other Overclocking factors at work, but last night i ran memtest to just make sure it wasnt the ram.
Low and behold, BINGO. memory errors showing up within half a minute.
Doing some more experimentation last night it seems that my memory has become "worn down",
and it won't run bug free with the 1T command rate, at ANY voltage or Mhz.
Can still run all other timings at Turbo though.
How very curious.
Anyway its good to know i found the source of the glitchy behavior.
I have had the same problem with my bros old stick of samsung 2100, the thing would run at 166mhz cas 2 no errors at default voltage bug free then it started to have errors and I had to gradually increase the voltage each month lol it finally died last month but it served me well and did one hell of a job for a stick of cas 2.5 2100 to be able to run at cas 2 3200. I just wonder why it died, I didn't bring the voltage that high and I had some heat spreaders on it.
Treat your body like a $600 car. God didn't intend it to last so use it. Run it into the ground!
