because AMD Athlon AM2 gains much more with memory speed increase, it would be better to publish the article "Choosing the Right Memory for Athlon X2 AM2"

G.Skill F2-6400PHU2-2GBHZ here tested is quite an old one model (0603) with Elpida chips! Newer ones (>0605) are made with Micron D9 (as stated on XS) and should perform much better. Am I wrong?

i picked up the mushkin ram. as stated, it would be great for an amd system. here's my results:

282 mhz 3-3-2-4 with 2 clocks for dram recovery time @ 1.9 volts

321 mhz 3-3-2-4 with 2 clocks for dram recovery time @ 2.1 volts

542 mhz 5-5-5-15 with 4 clocks for dram recovery time @ 2.1 volts

using seasonic 600 psu and asus p5w dh deluxe mobo.

As previously mentioned the G.Skill F2-6400PHU2-2GBHZ kit you tested used the Elpida IC. After May 1, 2006 they shifted to Micron D9xxx. These modules have a serial number beginning with 0605. The serial number with 0604 and older are using Elpida ICs. Somewhere around the 27 week of 2006 G.Skill changed the way that they identify their modules. They changed from using the month to using the week. So 627, 628, etc. are how the serial number for the HZ D9 begin.

I’m requesting that you obtain a new G.Skill HZ D9 kit and update your review. I’d bet that the G.Skill F2-6400PHU2-2GBHZ kit using the D9 ICs will then be the leader of the pack!

Great review. THis is why quality and testing is so important. Anyone can put out at 6400 part but if you want the best you have to go with the people that offer quality not go with something that is cheap and cant perform.

Mushkin and Corsair are great companies. We always give the consumer the best quality parts and do extensive testing to make sure our parts work in all types of real world application.

C4 does NOT use Micron chips anymore. there is no way you will push the great majorety of chips that high. Corsair XMS C4 use PROMOS IC's now, witch wont go near those benced in your test. The test is completely MUT, try doing a new test on the new C4 (v2.1 and up) and compare the results

The article is very informative but I would not assume a particualr chip under any heat spreader.

The Mushkin outperformed. Well it's should have at that price.

I know I am slow on the uptake, but its time you guys did a really exhaustive hynix vs. micron vs. promos vs elpida test. For example, Corsair changed the 6400C4 to use promos ics about a month after you wrote this. We have a pretty good idea what micron can do, but what about the other IC's? And someone over at vrzone just hit some ungodly overclock with some hynix chips. So maybe sample the variants out there and give us an idea of what the differrent ics will do and maybe find a few diamonds in the rough?

excellent article...

Thanks for explaining the true relationship of bandwidth and Freq, and help me avoid the misinformation and misunderstandings perpetuated in many other reviews.
You guys are are the real GURUs of information.

I have used this memory for 5 months, with an EVGA 680i motherboard, no probs.

Great Memory.

keep up the good work! ^^

Hi there!Just wanted to comment that GEIL Ultra 667 I tested on Ga M57 Sli,overclocked as far as 1130 @2,25v with looser timings 5-5-5-15 2t in single channel, and up to 1100 in dual channel mode.Ive been informed that these modules contain ProMos ic.So clearly,it is a matter of luck when trying every sticks other than micron based Ballistix...
