Performance Comparisons
Performance of the six 2GB memory kits was compared to the three 2GB kits tested in Part 1 of the 2GB roundup. Results are also generally comparable to earlier results on the nForce3 and nForce4 testbed using the AGP and PCIe versions of the NVIDIA 6800 video card. While we retested the first three 2GB kits in the revised test bed using the NVIDIA 7800GTX and the latest platform and video drivers, the results are not radically different from those in the old test bed, as long as you don't make too much of small percentage difference in memory performance. However, we have only reported results on the newest revised test bed to prevent any confusion about the influence of video card and drivers on the final results.

Searching for the Memory Holy Grail – Part 2
All nine of the 2GB DDR kits were compared at 200x12 (2.4Ghz, DDR400), 218x11 (2.4Ghz, DDR438), 240x10 (2.4Ghz, DDR480), 266x9 (2.4Ghz, DDR533) and the Highest Memory Performance Settings that we could reach. With a constant CPU speed, memory comparisons (except for top performance) show the true impact of faster speed and slower memory timings on memory performance.
Performance results for the fastest 2x512MB (1GB) kit that we have tested are included for reference at Highest Performance only. Including our standard OCZ 3200 Platinum R2, based on TCCD chips, allows you to compare performance at the top to the best 2x512MB kit that we have tested. For more comparisons to 1GB kits, please refer to earlier memory reviews linked above.
Keep in mind that Highest Performance is not comparing memory at the same multipliers. The factor of the overclocking abilities of the 400+ used for benchmarking comes in to play. For instance, a memory that reaches its highest overclock at a somewhat low clock frequency can actually have that clock frequency fall in the processor OC capabilities where it can run at a higher multiplier. The definition of Highest Performance is the highest clock frequency and multiplier that we could run with the tested memory and the standard 4000+ CPU. For a true "apples to apples" comparison, you need to look at comparisons at the same speed and multiplier.
Results of the retest of the first three 2GB kits are in green, the six new 2GB kits are in dark blue, and the Reference 1GB OCZ 3200 Platinum R2 results are in gold.

"... 2GB also makes sense for the OS future. With Vista coming and 2GB, the new memory recommendation for the new OS, you will be set for Vista."I was under the impression that the minimum is expected to be 512MB, and that 1GB will be recommended for good responsiveness under normal use. Having said that, I would personally choose 2GB for any new system as pairs of 1GB DDR (and of course DDR2) modules are now readily available and competitively priced. Unfortunately most big-name OEM systems are still shipping with either 512MB, or if you're lucky 1GB.

Being honest we have had some supply issues, and some issues regarding supply that are out of our control. We do have stock and will have more real soon.ocztony

This was to counter any moans about availability before they were posted.emilyek - Monday, January 23, 2006 - link
You guys tested the worst GSKILL kit.Their pc4000 2 gig kit (speed-binned version of that kit) is the same price as the 2-3-2-5 chip ($200) and will do DDR580
Their $250 kit 2-3-2-5 would contend with the Mushkin and the Crucial at a much lower cost.

The Silver Editors Choice Corsair 4000PT, and the OCZ PC4000 Gold and PC4000GX XTC, also based on UCCC chips, are all in the $205 to $230 price range for the 2GB kit from e-tailers. So $250 for a UCCC kit seems in line but hardly a bargain.As for testing the worst G. Skill, we asked all the memory manufacturers to supply their "best" 2GB kit for our roundup. The manufacturers decided what to supply, and we expect Enthusiast memory makers to know what is best in their line.

The crucial memory is amazing memory.I was able to get it stable at 3-3-3-8 @ 300mhz, but you really need to spend some time on the settings, it is VERY picky memory. Both tras and drive strength play huge factory in memory stability.
Yes, it is suspected that due to really high RMA they discontinued, however what anandtech doesnt report is what actually happens to the memory.
Even at 2.8vcore or less PLUS active cooling, 1 2 or 3 months down the line your memory will just start dying.
Thinks like memtest86 will check out fine, but then while gaming, your rig will just lock up. Random bluescreens, random lockups...
There is a big story to these ballistix, it is too bad they simply have a HUGE rate of failure. Do a ddr2 roundup, then you will see how many people use micron fatbodies for their high performance ddr2 memory. You dont see that with the high density memory, and obviously i suspect due to stability issues.
My advice for memory is the g.skill F1-4000USU2-2GBHZ based on samsung ram, it has been doing well, and g.skill has awesome customer service.
I personally am going to wait for ddr2 before going with 1gb sticks, then ballistix 2gb set is on my list. But that is just me.

I'm another Ballistix memory user here. I ran mine at 2.75v the whole time and they just died after a while. Screw you Crucial/Micron. I will NEVER buy your products AGAIN. (I don't care if they have zero problems eitehr.gooser - Monday, January 23, 2006 - link
Now what about the tracers?? I just purchased the 2 GB tracers last week knowing about the issues with the regular ballistix after a couple of months. I have read that the tracers use a higher quality power modulator, thus dont have the same problem. Anyone?lopri - Monday, January 23, 2006 - link
Lots of work and outstanding comments. Thanks. This review, along with the Part I, is significant in that it puts an end to the 1GB system memory standard. It's declaring that an *era* of 2GB system memory is finally here.However, with these super high-clocking 1G sticks (512MB sticks also for that matter), there is one *realer* question that's haunting my mind. With the current crop of DDR memory reaching speed of DDR550~DDR600, one has to wonder - What's the good if CPUs can't handle the speed of memory?
Yes, I'm questioning the capability of A64/Opteron's memory controller. Because even the best current AMD CPUs often fail to keep up with the speed of memory. You've got a PC4800 DDR memory? Good luck, pray your CPU can run it at that speed. This issue is, at least for me, very real. I just don't see the point of high-clocking memory when the truth is CPUs' memory controllers are the limit. (And to some extent motherboards, of course)
In the light of this, would it be possible for you to test the quality of each revision of AMD CPUs' memory controllers? Preferably with recent cores - namely, Venice, San Diego, Toledo, Manchester and their Opteron equivalents. The more detailed, the better. Rev E3, E6, E4, and even the steppings.
While reading this excellent review, I couldn't shake the issue of memory controller off my head. These days a stick of RAM seems only as good as the CPU's memory controller it relies on. Unless one is just happy to see her/his RAM passing memtest @DDR600 all day long.
Again, thanks for your hard work on this review, Wesley. However, I'd really like to hear from you about the issue that I'm bringing here. I'd much appreciate it.

If my CPU can't keep up with my RAM, I just drop the multiplier (and/or divider) down until I find the point where both run as high as possible at the voltage and temps I'm comfortable with.
