G. Skill F1-3200PHU2-2GBZX
G. Skill entered the US market at about the time that Samsung TCCD memory was launched. G. Skill capitalized on the incredible performance of TCCD and produced some excellent TCCD parts that were marketed to enthusiasts on many Forums. We reviewed the early TCCD in PQI & G. Skill: New Choices in 2-2-2 Memory and found that the G. Skill performed very well.
Specifications
G. Skill rates their 1GB DIMMs at DDR400, which is usually an indication that B die Infineon memory chips were used.
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.
Test results also point to Infineon B die chips. The G. Skill 2GB kit is very fast from DDR400 to the highest stable overclock that we could achieve at DDR516. This is a very high overclock for B die Infineon memory, showing G. Skill has not lost their expertise in squeezing the most out of the memory chips that they use. If fast performance with 1GB DIMMs from DDR400 to DDR500 will meet your goals, then the G. Skill 2GB kit is a good choice. The only problem, compared to other 2GB kits, is that C die Infineon is just as fast at lower speeds, but C die continues to overclock to DDR550 to 580.
Like the Corsair Infineon B die that we reviewed in Part 1, the G. Skill is a memory that does not need a special board with super high voltages to get the best from the memory. You can get the best from these 1GB with almost any decent motherboard, since we never needed more than 2.8V for stable performance at any speed.

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?
