Foxconn’s FlamingBlade
has the highest stable memory speed of any motherboard we’ve tested, and that makes it a great choice for overclocking today’s test modules. We set its BIOS to 1.65 V DIMM and +0.36V CPU VTT (Uncore) for today’s test.

Unfortunately, we found out after testing began that this particular motherboard and BIOS has a bad habit of resetting tRAS values at reboot. Timings of 17, 18, and 19 were frequently reset to 16, while timings of 13, 14, and 15 were similarly reset by the motherboard to 12. This would often prevent reboot, causing either a loss of custom BIOS configuration or an “overclock failure” message. Reconfiguring BIOS at every error was nothing more than an inconvenience, but anyone using the FlamingBlade for memory testing needs to know about this issue.

    Great review, this helped me determine with determining about DDR3 6GB kits. Since I'm in the middle of building my core i7 rig. thx!
    btw, isn't there any cheaper ram on the way as well?

    These were all available for under $90 at the July 3 price deadline. Amazing what's happened since, eh?

    rather silly not to include any gskill ram

    Is 1.65v really needed?
    I recently built an i7 mashine with 2x6gb ocz gold modules.
    Instead of running them at their rated 1600mhz @ 1.65v I decided to go for 1333 @ 7-7-6-17 - and that @ stock 1.5v ; I don't really get the point of feeding them more juice just to get timings a tad lower, or frequency a tad up.

    With the minimal performance gains from high-end RAM, glad to see an evaluation of the "cheap" stuff. Good work.

    OCZ DDR3 3x 2 GB kits, the Gold and the Plat at 1333 and 1600, dropped below 100 bucks at NewEgg and ZipZoomFly three months ago. They've been $89 - 99 PLUS a 20 rebate with FREE shipping there on and off since April.

    The statement at the heading is inaccurate.

    I picked up some 12gb ocz platinum 1333 kits for $135, and 140 off of amazon. Found them using bing.com/cashback.

    do not use ocz's xmp set the memory yourself. On my memory the 1600mhz with xmp i tried the xmp 1600 setting and it cooked my i7 cpu. After the shitty rma process i installed the memory and set all the timings myself and found out that the xmp profile set the qpi voltage to 1.4 when it runs fine on 1.105 (i think) the default qpi voltage anyways i learnt my lesson ocz might have cheap memory but dont use the xmp.
