Performance Test Configuration
The six 2GB kits were tested with the DFI LANParty nF4 SLI-DR Athlon 64 Socket 939 motherboard. Other components remain the same as used in the memory setup in Athlon 64 Memory: Rewriting the Rules.
The A64 test bed includes components that have been proven in Socket 939 Athlon 64 benchmarking, such as the Socket 939 90nm 4000+, the OCZ Power Stream 520 Power Supply, and the NVIDIA 7800 GTX video card. We used an AMD 4000+ 90nm processor with a Revision E type memory controller. All other basic test conditions attempted to mirror those used in our earlier Athlon 64 memory reviews.
Since the video card, and platform/video drivers are upgraded from past memory testing, we found that the results were not completely consistent with past memory test results. For that reason, we retested the three 2GB kits that were previously tested. Results are still broadly comparable to past memory test results in earlier reviews, but we decided to include just the nine 2GB kit results in this roundup.
As discussed in other memory reviews, we ran a complete set of Memtest86 benchmarks with only tRAS varied to determine the best tRAS setting for these memories on the nForce4 chipset. The NVIDIA nForce4 has the best bandwidth at tRAS settings ranging from 5 to 8. Therefore, a tRAS setting of 7 was used for testing.
Test Settings
All AMD Athlon 64 processors are unlocked downward, and the FX CPUs are unlocked up and down. This feature allows a different approach to memory testing, which truly measures performance differences in memory speed alone. All tests were run with CPU speed as close to the specified 2.4GHz of the 4000+ as possible, with CPU speed/Memory Speed increased at lower multipliers to achieve 2.4 GHz. This approach allows the true measurement of the impact of higher memory speed and timings on performance, since CPU speed is fixed, removing CPU speed as a factor in memory performance.
The following settings were tested with the six 2GB kits on the DFI nF4 test bed:

The following settings were tested with the six 2GB kits on the DFI nF4 test bed:
- 2.4GHz-12x200/DDR400 - the highest stock memory speed supported on nF3-4/SiS755-FX/ATI Radeon Xpress 200/VIA 939 motherboards
- 2.4GHz-11x218/DDR436 - a ratio near the standard DDR433 speed
- 2.4GHz-10x240/DDR480 - a ratio near the standard rating of DDR466
- 2.4GHz-9x267/DDR533 - a memory speed achieved by only a few top memories on the Athlon 64
- 2.4GHz-8x300/DDR600 - with recent improvements in OC abilities, a very few memories can reach this next multiple with the 8 multiplier
- Highest Memory Performance - the highest memory bandwidth and game performance that we could achieve with the memory being tested. This is the highest memory speed that we could achieve with 1T Command Rate.

Crucial use to be a pretty good memory supplier at one time and I've bought plenty of their products. There seems to have been a philosophical change at Crucial a number of years ago and I stopped buying and recommending their products after a major hassle over one failed DIMM out of the many we had purchased. Seems like their submission of a discontinued product to this 1 Gb review is another example of mis-management and manipulation of the media...In regards to 1 Gig. DIMMS vs. 512 Mb it seems to me relatively few people really need these DIMMS. If you are a serious gamer playing the latest game versions, sure you'll see some small performance improvement for a PRICE. And that is the point really - what do you get in tangible system performance gain and is it of enough emotional value to you to pay the premium price. Obviously for some it is as they will pay $1000 for a CPU, $700 x 2 for 7800 GTX 512 Vid cards, etc. I doubt however that most PC enthusiasts can really justify those prices nor the price premium for 1 Gb DIMMS based on system performance gains.
And along those lines... how often do PC enthusiasts and / or gamers replace their entire PC hardware??? If for instance you are building a new PC now because the Opti 165 / X2 3800+ are a sweet deal, would you really be in the market for a new AMD AM2 system in a 4-6 months when they are readily available??? I doubt many folks replace their hardware that often but I could be wrong. If it is true then I wonder where all the good hardware ends up after it's used for a couple months and then trashed for the latest trick-of-the-week hardware???

its called ebay - or as some say "egay" :por I think option 2 is the not so rich friends who suck up a lot
option 3 is "damn, I overvolted the cpu to attain max overclock and the damn thing fried itself -- oh well, just buy another fx-60"
note that option 3 people probably fuel the reason for why manufacturers think they can charge us $500+ for a gfx card and $1000+ for a cpu

Worth note - and not shown in the benches here - is that 2GB of RAM can have a massive impact on load times for some of the latest games. It is also incredibly useful when you're editing a bunch of images in Photoshop. The difference in level load times on BF2 is amazing, even when comparing 4x512MB 2T to 2x512MB 1T.BF2 is something of an exception right now, but over the next year I expect more and more games to push the memory requirements beyond 1GB. FEAR is another reasonable example, though not quite as pronounced as BF2. Some of the MMORPGs also get a lot of use from 2GB.
Personally, I won't be buying 512MB DIMMs anymore, but I still use them in systems I build for other people.

Why is the OCZ PC4000 XTC and Normal Gold not covered in either article??? The Platnium EB's are too much money, and i would like a good read and comparison on the XTC/Golds. As a side note, Crucial stopped making their 2GB DDR1 kit, so they couldnt replace my dead det, which is why i got the OCZ'sbigtoe36 - Monday, January 23, 2006 - link
XTC and golds do feature the same IC, OCZ are moving to replace all old heatspreaders with XTC so you will see some older stock using the old spreader in stores.So apples to apples they should clock near the same but the XTC moduls running a little cooler.
johnford64 - Friday, January 27, 2006 - link
But my question is why neither XTC or Gold kits have been reviewed here, if there have please let me know whereMiggle - Monday, January 23, 2006 - link
not much difference (in RTCW at least) between 400mhz and 533 (must be the timings). Good review tho.Now, i'm looking for a link that shows how mem timings impact A64 (2-2-2-6 vs 2.5-3-3-7). Hope someone could give me one.
still, me thinks that fast mem = costs too much and not that worth-it. I just bought geil value ram that does 2.5-3-3-6 @ 200mhz and quite happy /w it (on AXP still tho).

I was just trying to decide about my next system whether I should wait for DDR2 or increase the memory on my old system. I think I'm going to wait for DDR2, hopefully AMD will roll out 65nm around the same time as the new socket. And prices will be reasonable and availability will be high. Guess we'll wait and see...Nocturnal - Monday, January 23, 2006 - link
Crucial recently pulled their Ballistix 2GB kits due to unforseen circumstances. Everyone at XS is speculating that all of the RMAs that have been going on is culprit.johnford64 - Friday, January 27, 2006 - link
That happened to me, 2 dead kits. They tried to offer me 2GB of PC3200. Like hell i am taking $150 ram in place of my $400 USD ram.
