Looks like you're asking everywhere ;) 

There's
Set 1 http://www.ocztechnology.com/ocz-ddr3-pc3-12800-intel-i...
OCZ3X1600R2LV6GK
1600 8-8-8-24-2N @ 1.65v

Set 2 http://www.ocztechnology.com/ocz-ddr3-pc3-12800-reaper-...
OCZ3RPR1600R2LV6GK
1600 7-8-8-24-2N @ 1.65v

I'm assuming Set 2. The set 2 per the OCZ site lacks XMP which is the easiest method so Manually it is:

BIOS:
Ai Overclock Tuner -> Manual
DRAM Frequency -> DDR3-1600MHz
DRAM Timing Control /Enter
DRAM CAS# Latency -> 7
DRAM RAS# to CAS# Delay -> 8
DRAM RAS# PRE Time -> 8
DRAM RAS# ACT Time -> 24
-
DRAM Timing Mode -> 2N
-
DRAM Voltage -> 1.64~1.65v {depends on menu}
-
QPI/DRAM Core Voltage -> 1.30v ; optional but it's better to set manually.
-
Save & Exit = Yes

Test with Memtest for at least 2-passes, create a bootbale CD/DVD and use the ISO/zip file -> http://www.memtest.org/

Good Luck! :)

Better RAM = same; OCZ got out of the RAM Mfg business. Theoretically, the OCZ3RPR1600R2LV6GK 1600 7-8-8-24-2N @ 1.65v, but I typically don't like loose CAS and prefer 8-8-8-24.

Any of the other CAS timings beyond 7-8-8-24-2N leave them alone the BIOS will adjust properly.

Good Luck! :)

ok thanks for your help. I had 1 stick of my 12gb of OCZ3X1600R2LV6GK ram fail and OCZ replaced them with 12gb of OCZ3RPR1600R2LV6GK ram did i get a good deal?

The OCZ3RPR1600R2LV6GK looks to have a better cooling sink though it's Gigantic. My only real concern is clearance to some HSF e.g. Noctua NH-D14, but they should run fine.

Take Care! :sol:

Thanks for the best help one could ask for :) . I was concerned about size aswell. I am using the stock DBX-B heatsink that is included with the i7 980x and there is just enough room for 6x 2gb OCZ Reaper HPC

Thanks again - Live Long and Prosper ;)
