Crucial Ballistix CLIII5N.32 PN56278
As the retail sales arm of Micron, the huge memory chip manufacturer, Crucial has managed to impress us many times with their high-end Ballistix memory line. The Ballistix name is almost always means high performance, but it also normally represents good value in the memory market.
Specifications
The Crucial Ballistix 2GB kit is rated at DDR500 at the somewhat conservative ratings of 3-3-3-8. We actually found that the DIMMs would run at much better timings at DDR500. We could run the DDR500 speed at 2.5-2-2-7 at 2.8V, which is the best performance that we have ever seen at DDR500 with 1GB DIMMs.
Voltage is rated at standard or 2.6V.
Test Results
To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and Comanche 4 had to complete without incident. Any of these, and in particular Super PI, will crash a less-than stable memory configuration.
Crucial Ballistix has been available for several months and the performance characteristics are pretty well known. We achieved incredible results with our Crucial Ballistix, but our results should be considered among the best that you can achieve with these 1GB DIMMs. Where we were able to run at 2-2-2 timings at stock voltage, we more commonly see results at DDR400 of 2-3-2. This is not to take anything away from the Ballistix 2GB kit, as it is definitely an incredible performer at the more normal results that we see in Forums.
One word of caution: some users have been killing their Crucial Ballistix 2GB kits. It appears that the culprit is high memory voltages. We did a survey of a number of Forums and found that, in most cases, the memory was dying at voltages of 2.85V and higher. Our advice, which we also followed in benchmarking for this review, is to keep voltages below 2.85V with the 2GB Crucial Ballistix kits.
The other end of the spectrum was also outstanding for Ballistix. We reached a stable DDR610 overclock at 2.8V with the 2GB kit. This is the highest overclock achieved with any of the nine 2GB kits tested in this review. Our only real reservation with Ballistix is the spotty availability that has characterized this product since launch. This "on again, off again" availability is usually an indication that yields may not be as good as a manufacturer would like. We don't know the real reasons why 2GB Ballistix doesn't stay in stock, but you should be aware of the supply problems before deciding on this 2GB kit.

I don't anticipate DDR1 prices changing much, and once AM2 comes out I expect prices to start climbing as DDR1 productions halts. DDR1 prices seem to have hit bottom about 6 months ago, and they're already starting to rise - at least on the budget parts.Thor86 - Monday, January 23, 2006 - link
Did I miss this in the review? If not, it would help if you told us what memory settings used in the DFI bios for these sticks reviewed.Wesley Fink - Tuesday, January 24, 2006 - link
I used the 7/06 BIOS, which is basically the Bigtoe BIOS. I have found this BIOS to be remarkably compatible with a wide range of memory. All memory settings were left at default except the 4 reported memory timings (CAS to TRAS) and memory voltage in testing all the memory. We did not do any special tweaking, which is another reason we reran tests with the 3 2GB kits tested earlier. You can definitely achieve better bandwidth and higher scores than we did by tweaking memory in the DFI BIOS.keldog7 - Monday, January 23, 2006 - link
I was surprised to find your review stating the Corsair 3500LL could only reach 492 MHz...especially when out of the box, I clocked mine to 500 MHz. This required no special tweaking of the other timings, other than what's listed below. Any careful research on this memory, using the many online reviews of it, show that the RAM runs fine (at slightly relaxed timings), well into 500Mhz territory, and beyond.In my case, I've got it on an A8N32SLI, at 2.7V, running 2.5-3-2-7 1T with a 1:1 divider at 250Mhz. In my case, this has been verfied to be Memtest86+ stable for at least 12 hours (last run was 90 hours...then I had to stop it to actually get some work done!)
I wonder if the motherboard used in your review has biased your overclocking results?
Wesley Fink - Monday, January 23, 2006 - link
According to my review notes, the Corsair 3500LL Pro cloked to almost 260 (DDR520) on Super Pi and Sandra memory tests, but the highest we could do with stability on 3D tests was 246 (DDR492). There is always varaition in memory results.Since you criticize my results as being too low for your memory and another reader criticized my results as being too high for his memory, it is likely my results are typical of the range of results readers might achieve. Some will do better than my results and some will do worse. Overclocking results do vary among memory samples.

Unless Anandtech got really good batches of Infineon ICs, I don't buy the analysis. There have been numerous reports of 3D instability issues...I've experienced them myself with the Redlines. They are primex2 and memtest stable at fairly high speeds (270) but only 3D stable near spec (250ish).entrecote - Friday, January 27, 2006 - link
Neither do i buy it.I invested in a pair of the mentioned 2GB Mushkin Redline PC4000 memory. I´ve stubbornly been trying to tweak them on my DFI Lanparty + X2 Toledo processor for two months. This Redline kit of mine refuses to surpass 252MHz / DDR504. One module does 256MHz / DDR512, the other one does 252MHz / DDR504 regardless of timings. Trust me, I´ve tried all combinations of different drive strenghts, Trefs and so on. My case is not isolated, I have the same symptoms as the perhaps majority of 2x1GB Redline owners, "3D instability".
My thoughts on the matter is that Mushkin was aware of this bad batch of theirs, possibly due to quality fluctuations of infineon modules. Then they quickly began to separate a few review samples for marketing puposes. I went through the same dissapointment one year ago when buying PC3200 Ballistixs after quickly reading through among other reviews anadtechs infamous "Ballistix cherry pick" DDR roundup.
I put great trust in anandtech, please do me a favor in the future to only review retail samples of memory. Some of these mentioned brands purposefully send special samples to rewievers.

We reported what we found, and 3D tests are part of our benchmarking. The OCZ for example was Super Pi and memtest stable to 290, but 3D dropped the stability to 275 (DDR550) which we reported. The Redline went well over 300 on memtest and Super Pi, but 293 (DDR586) was our highest 3D stable.What memory controller revision are you using with the Infineons? Our tests are with a Rev. E, and we have seen lower performance on the older clawhammer memory controllers with the 1GB dimms.

I have a rev E6 Opteron 170. Perhaps I just got an unlucky set of sticks, but the forums are loaded w/ people with similar issues, particularly around 3D.Duonger - Monday, January 23, 2006 - link
the mushkin parts have been back in stock for over a week now and is available (if not sold out already) on Newegg and on Mushkin`s Site.Wes- the ocz parts u compared. those are 2x512mb kits. why did u include it on this 2gig round up?
