Pros: I put this RAM in my GA-x48t-dq6 mother board. It rebooted twice and came up in defalt auto settings, but then I began manual timing settings and testing. The BIOS recognized all 8 GB of ram. I'm running dual boot XP/Win 7 x64; Win 7 recognized all 8 GB and XP only 3.5 GB (that was expected, had same with 4 GB). I have run this memory for 24 hour testing of MemTest and Prime 95 over a full month for 8 different timing profiles. I now have 8 different timing profiles to choose from; starting at 696 21@ 1338 to 797 23@1602. These are rock solid. I run the DDR3 voltage @ 1.63V, except the 797 23 @1602. It's at 1.68V and has to run at 1T -- won't pass MemTest test 5 on 2T. Puts new life into an x48 board.

Cons: Not really a con, but I was able to run my old OCZ Platinum 2x2GB at 555 15 1T&2T timing. The Mushkin won't go that low, computer will not POST at 555 15. I suspect that's due to the double amount of ram or it could be my board.

Overall Review: This is great ram! I even get CAS 7 now, the OCZ Platinums would not run stable at CAS 7. I bought this ram in December for $59.99. That's $40 less then what Newegg is asking for now. What ever mobo you put this RAM in, you will not be disapointed.

Pros: Replaced a 2x1G kit of OCZ3P13332gk for the 2x2G kit of OCZ3P13334GK. Started with stock timings and voltages on a GA-x48t-DQ6 mother board. After 2 weeks of tweaking and days of testing in Memtest86 and Prime95, I am now running at 6 6 6 20, trfc 71, tDR 7 and 1T. Had some help from OCZ tech support to start with recommendations on initial settings when going from 2G to 4G. Very helpful!

Cons: None!!!! Could have used some help lifting that Thermaltake Armour case ... HEAVY, but very, very good!

Overall Review: I think one of the reasons I have had such good luck with tweaking these memory sticks is due to the mother board and the case. I liked the CrazyCool heat sink that was on the back of the mother board, but putting on a Zalman 9200 cpu cooler, it got in the way ...so, something had to change. So, I took a hackwaw to the heatsink and cut off just enough for the new cooler to fit, but enough under the NorthBridge to help cool. Add the Thermaltake Armour case with 23 cm side fan which blows right on the ram and NorthBridge and all motherboard heat sinks and all is cool ... system seldom goes over 31C. Not over clocked. System: GA-x48t-DQG, E8400 Wolfdale, Zalman 9200, EVGA 8600GT Overclocked, 750W Cooler Master power supply.
