Just been testing the Geil value RAM (DDR2, 533MHz, 4-4-4-12, 1.8V) that I got from OCUK yesterday.
Stuck 'em in my PC and set them to 800MHz, 5-5-5-15, 2.0V and left Memtest86 for a few mins, they failed after about 10 minutes, I left them for longer and even more errors came up
So then I went into BIOS and changed them to 800MHz, 5-5-5-18, 2.1V and errors occured again.
Then tried 667MHz, 5-5-5-15, 2.0V and they failed AGAIN.
Lastly I stuck 'em at default values of 533MHz, normal V and 4-4-4-12 and they STILL bloody errored !
So basically have I screwed them up by pushing them to 800MHz ? Shall I RMA them to OCUK ? Or... ?
