Listmates,

	I have received and had to RMA 2 sets of OCZ Platinum DDR2 1066 in the past 
week (the first set painted the memtest86+ screen red right off the bat, the 
second set (2 2-gig sticks), just one stick was bad that failed test 7). 
Literally, the replacement RMA set was bad. What gives? Bad run of silicon? 
Anyone else bought any in the past few weeks? Surprising, because other other 
than a couple of prior OCZ RMAs over the years, I really haven't had any 
problems with OCZ.

	For the on-topic part. If anyone is relatively new to memory errors, then you 
need to know memtest86+ is your friend. If you experience stray lockups or 
other random hardware failures (mouse just quits, usb devices (drives) just 
disappear or quit working, etc..), then install memtest86+ which becomes a 
grub menu boot option you can select to boot into memtest. 

	Generally, you just start it and go do something else for a while and let it 
run (it will loop through its suite of tests continually and each complete 
pass can take up to an hour or more depending on how much memory and your 
other hardware specifics) You can also configure memtest86+ to some extent 
while it is running. Press 'c' and you can skip tests, reset, etc..

	How many memory errors are acceptable - ZERO! If you see any red on the 
screen you have problems. Do all problems mean fault memory - NO. You need 
check your bios to make sure your bios memory setting (CAS timings, etc.) are 
not set to 'tight' or 'lower' than what your memory specifications are. Try 
loosening/raising the bios memory timings  or set them to "Auto" and retest 
before you throw in the towel. If your settings are set to "Auto", which most 
are, then you should be fine on the settings.

	If after confirming your bios settings, you still see red in memtest86+, it's 
time to RMA or warranty your memory. You can still narrow down which stick it 
is by removing the sticks and testing them one-by-one, but if you purchased a 
dual-channel kit, they're both going back anyway...

	Now back to my question, anybody else seeing bad sticks of OCZ DDR2 lately? 
Thanks.
