DDR3 On A Budget: Six 6 GB Memory Kits

Test Results: Latency, Frequency And Bandwidth

The highest memory speed represented in today’s budget 6 GB comparison is DDR3-1600, so we used this as the highest speed for latency tests, looking for any improvements at the three standard speeds all six modules could potentially support. All modules were set to 1.65 V, allowing the slower DDR3-1333 sets to compete on equal footing for best DDR3-1600 latency.

Best Timings at 1.65 Volts

DDR3-1600
DDR3-1333
DDR3-1066
Corsair DDR3-1600 CAS 8

OCZ DDR3-1333 CAS 7

Patriot DDR3-1333 CAS 7

Corsair offers the lowest DDR3-1600 CAS latency, while OCZ offered the tightest timings at DDR3-1333 and DDR3-1066. Crucial, Super Talent, and Patriot finished so close one might suspect that these were all based on the same memory chips.

Corsair also leads in overclocking, edging out the basic Crucial modules by a data rate of 29 MHz. Of the three modules that supported nearly-identical timings at various speeds, the set without the heat spreaders (Crucial) leads.

In Sandra Memory Bandwidth, OCZ’s lower tRP appears slightly more significant to our Core i7 platform than Corsair’s lower tCAS.

At DDR3-1333, OCZ’s lower tRP again trumps everything.

Patriot’s lead at DDR3-1066 doesn’t make much sense, but the results are so close that it's hard to call this victory significant.

    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.

    what about kingston ram?

    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
