Athlon 64 Memory: Rewriting the Rules

G. Skill TCCD
This is our first look at G. Skill memory. You can learn more about this Taiwanese memory maker at www.gskill.com.tw. G.Skill was established in 1989 by Enthusiasts and specializes in the production of memory.
With a name of G. Skill TCCD, the memory chips should be obvious. This is another DDR sporting Samsung TCCD chips. Where G. Skill is a bit different is in rated speed of the memory. G. Skill actually quotes three different speed ratings - DDR400, DDR500, and DDR560. We have seen recent TCCD DIMMs reach DDR500 and beyond, but this is the first TCCD DIMM that actually specifies speed ratings to DDR560. The Samsung TCCD DIMMs are part of the G. Skill Extreme series and they carry a lifetime warranty.
You will also notice that there are no heat spreaders on the G. Skill DIMMs. Frankly, we have seen little, if any, cooling advantages with heatspreaders, so their absence will not be an issue to most. Heatspreaders are more often a cosmetic appearance item. They also appear useful when manufacturers want to make it a bit more difficult to determine the memory chips used on the DIMM.
Test DIMMs were a 1GB kit, a matched pair of 512MB double-sided DIMMs.

I ordered from Newegg today. I did not see a place on their site for just a 512mb stick. I ordered the 1gb kit.http://www.newegg.com/app/ViewProductDesc.asp?desc...

hey bugler where are you ordering your ocz platinum rev. 2 from? is there any way to find a place where you can order 1 512mb stick only?darkwaffle - Friday, October 1, 2004 - link
I'm curious, for a socket754 user, is there really any reason why we couldn't (generally) follow these results? I realize that some of the overclocks may not be able to be achieved, but is it safe to say that the modules that perform highly on s939 will also perform highly also on s754 (In comparison to the other modules)?Wesley Fink - Friday, October 1, 2004 - link
#32 -Corsair and Kingston DDR400 2-2-2 were both included in our recent 2-2-2 roundup. Frankly we did test both Kingston and Corsair in the early going for these tests and both did quite poorly on the Athlon 64 test bed compared to other recent TCCD modules.
However, the Kingston and Corsair were early TCCD dimms and we are confident more recent dimms from these two major manufacturers would perform more like the OCZ, Geil, and G. Skill. Unfortunately we didn't have those more recent dimms to test, and we felt reporting what we had found would have been very unfair to Corsair and Kingston, who both produce excellent memory products.

I'm sure OCZ and Geil are great memory for A64, but all I got out of that article was buy OCZ memory, buy Geil Memory, o ya and buy a top of the line OCZ power supply....What about Corsair and Kingston? How do they compete?
This site is smothered with advertisement. Why make it so obvious in the articles? Thanks for the article though...

And re: the robust +12v rails. They are most crucial for A64 overlocking. I have an Enermax with 31A on two +12v rails and it makes the world of difference.einsig - Friday, October 1, 2004 - link
One thing that really needs to be stated is that Clawhammer cores automatically set a command rate of 2T at speeds from DDR400 and up. you need to use A64 Tweaker to make the change (can be loaded at startup). I have a Clawhammer 3400+ that has been run on an ASUS K8V Deluxe and MSI K8N Neo Platinum. I was running XMS 2x512 3200LL Corsair, but it didn't want to OC even on the K8N (nothing OCs on the K8V because of the chipset). I now run Crucial ballistix PC4000 and it is incredible, however (as the article states) the command rate of 1T is really ideal. They should just tell people how to set that if they have a Clawhammer.Shinei - Friday, October 1, 2004 - link
What's really exciting is that the two DDR600 overclockers are board-limited before they top out in speed (K8N Neo2s go to 300MHz on the RAM). I'd like to see what the RAM could do on a more extreme overclocking board, since it seems like these new RAM chips are capable of pushing on to DDR667 or even higher...With that said, I agree that the prices for this stuff is getting ridonculous. Cheaper RAM means more sales and increased usage of that 8 exobyte storage capacity the Athlon 64 has. ;)

Thank you AnandTech. I have been waiting for greater clarification since you last recommended OCZ 3700 enhanced bandwidth ram and none could be found. I was balancing between that and ballistix. After today's review, I ordered OCZ Plat, rev 2 for the system I am putting together.Now if we could get some reviews and testing of the newer 90 speed AMD processors, hint, hint...
I appreciate this site very much.
