ok guys now i really need ur help, this is some of my recent communication with RAMGUY over there at corsair forums:

hi Ramguy,

ive bought 2 x TWIN2x4096-8500C5D G kits like 3 months ago and immediately ive started getting spontaneous system restarts once every two days or something, i thought it was my vista ultimate 64 acting imperfect like it is but then i started clocking the system and i noticed theres always failure in blend mode in prime 95, yesterday i tested all sticks separatelly in blend and all came thru for coupla hours xcept this one stick which always failed within first 2 minutes, now the question is, even though i can boot and play games and do everything with this "faulty" dominator stick, should i RMA or are occasional restarts and OC instability something i should live with?


Ramguy:



I would recommend using www.memtest.org to test your memory configuration. Load setup defaults in the BIOS and then manually configure the following settings:

Memory Votlage: 2.1v
Memory Frequency: 1066MHz
TCL: 5
TRCD: 5
TRP: 5
TRAS: 15
Command Per Clock: 2T

Test each module one at a time in the slot closest to the CPU, if you get 3 modules which pass, and a single module giving you errors then you likely have a failing memory module. If all the modules pass or all the modules fail, then there may be some other issue. Let us know your results!

Here is a guide to help you with memtest: so i followed his guide and burned a memtest iso to a bootable cd and setup bios exactly as he said and left memtest86+ overnight and when i woke up there were 24 passes and not one error, 24 damn passes with 8 tests each and no errors! and then i boot windows and start prime 95 and voila it fails after less than 1 minute, this stick was always failing blend after less than 1 minute while all the other sticks were stable, and now this stick does 24 passes with no errors??? how the hell am i to interpret that???
