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.

If you get the chance, can you please test with 2GB of PC3200? I’m sure most would love to see what type of performance hit there will be with the larger modules vs. the smaller ones. Looking at the benches so far, it looks like even buying the cheap 1GB PC3200 modules will have negligible impact on the performance as long as the times are kept relatively low (under 3cls.) And one more big IF you could test 4x512 PC3200 with lower clock timings (2-2-2-5) vs 2x1024 PC 3200 with timings of (3-3-3-8) I’m sure that for the average user they would rather blow $400 for 2GB of slow memory then $400 for 1GB of fast memory.Zebo - Friday, October 1, 2004 - link
spensive!:(p/p is horrendous for this stuff. It's too bad you don't include micron/crucial 8t in there which can also clock to 260 for half the price.

I've loved all of these recent memory articles. For a while now, the current state of memory in general has been the fuzziest for me. Now I'm starting to get a clearer picture of where things are at and which direction to go. I'm still nursing along my old P4 Northwood, but the A64 plunge is imminent. Nice to see that memory development is keeping up at a strong pace what with 600 MHz speeds now a strong reality.RaistlinZ - Friday, October 1, 2004 - link
Thank you for the great article! From your tests it looks like the OCZ 3200 Rev.2 is the best of the best. It performed near the top in every test and edged out the Crucial Ballistix at the highest speeds.I guess my choice for a memory upgrade is clear now. :)

Seems you cut something off at the end of page 9"We have asked AMD to provide some insight into why we are "...
