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?

    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.

    Maybe you live in an area where usual temps are 10-30* celsius, but don't forget that there are people who live in areas where at summer things can get really hot so I don't understand why not add at least a warning saying that overclocking this ram is really not safe unless you know what you're doing.

    I know lots of people who read toms hardware occasionally and don't know a thing about computers - have cramped cases without proper ventilation and low-end ram without heatspreaders. Temps around here in July-August are around 40*C. Do you think it's smart if they were to overclock their ram? Because that's actually what you imply..

    I got my 6 GB 1600 DDR3 GSkill kit for $95 with free shipping back in March. Run's rock solid at 8,8,8,21 on 1t timings.

    Where do you live that 40C is the norm in summertime? I live in Atlanta and 35 is average. Even South Florida doesn't really get much hotter.

    I tried this memory.... it SUCKS! This memory caused my computer to crash every single time I tied to run prime95!

    Half of them do, read the descriptions.

    The Intel Extreme Edition was cheapest on July 3 when testing began, and the prices were updated the day before the article was published. No Gold or Platinum available for under $99 on August 5, since venders listing lower prices were out of stock.

    MonkeySweatwhat about kingston ram?


    Everyone was invited, some companies chose not to participate. In particular, some companies don't like overclocking articles that promote their cheaper modules at the expense of some high-end product sales.

    Wow, you tried all of them? That's really sad.

    Looking forward to likely a 8GB 1600 set myself.
    Ramdisk FTW!

    For my purposes, the 1600 is still over. With the i7/Core2, we have proven thus anything over 1066 useless in most games already. It may be different with the i5, but I doubt it. I just want cheap quantity at the moment.

    I was running the ram at it's rated speed it was not an overclock I bough the 1600mhz kit that's shouldn't be hard to understand also everyone in the 2009 will have a/c in their house or apartment so it's not like I'm running my computer on some Mexican beach. Ocz XMP profiles are not clocked properly on the 1600 kit because it gives the qpi to much voltage causing the CPU to overheat. CPU is running stock clocks stock heatsinks. Before you run your mouth use your brain thanks. PS the memory works great you just have to set the clocks yourself
