RAM quality question...

Awhile ago I bought an ECS KN1 Extreme Lite Mobo and an AMD 64 3400+ along with a cheap 1GB ram stick. After lots of testing, I've found that running the RAM at 1T (it's rated at 1T and if set to "auto" in bios it indeed runs at 1T) the ram fails memtest86+ like nobody's business. When I run it at 2T it performs perfectly.

My question is .... is my ram BAD? Or is it BAD QUALITY? In other words, is memtest the be all and end all of RAM, or will I inevitably end up with corrupted data at 2T even though memtest passes it at 2T. And if I buy a higher quality 1GB stick later to run dual channel, will I again most likely be restricted to 1T? Thanks.

Moderately overclock and overvolt the RAM @ 2T and let it run Memtest86 overnight. e.g. Run it at DDR440 ~ DDR460 with 2.7V ~ 2.8V @ 2T or so, whatever is stable.

If it is still running in the morning and stable, the RAM is not very likely failing or in accelerated decline. The only definitive way to test it is in a hardware-based RAM diagnostic machine (which start at a couple grand), but the above method is fairly reliable.
