In the computer industry, Revision 2 or Revision B products are somewhat rare. Products that were not well received come back with improvements and a new name. In addition, the speed of innovation is amazing in the computer industry, with new chips, chipsets, sockets, memory types, and AGP standards constantly just around the corner. On the rare occasion where we do see a revision announced, it is usually a revision to a best-seller or legendary product in our industry. OCZ PC3700 Gold Rev. 2 falls into this category, but the Revision is more than just a new name for marketing.

OCZ PC3700 Gold was the first memory tested at AnandTech that was able to perform at DDR500. Since that time, just a few months ago, there have been a lot of new DIMMs that are rated at DDR500 or higher. Corsair is even shipping a DDR550 (PC4400) module. We have also tested modules that are rated at DDR533.

Despite the new higher-speed memory available, PC3700 Gold is still much in demand and is used in many high-end computers because it also performs very well at DDR400 to DDR500. This makes it a good choice for those who want DDR500 capabilities, but also want good timings for DDR400 and the 5:4 memory ratios on Intel 875/865 chipsets. The only complaint about the original 3700 Gold was that it was only available in 256Mb Double-Bank DIMMs; 512Mb modules were not offered. OCZ tells us that the hand-picked and lasered Samsung chips used in the original Gold did not allow a 512Mb option, and they are also dealing with increasing supply problems for those chips. For both of those reasons, we are now seeing a Revision 2 based on different memory chips, and finally, the option of 512Mb modules of OCZ PC3700 Gold in Revision 2.

PC3700 means an official rating of DDR466, just like the original 3700 Gold, and the rated timings are 2.5-3-3-7 at 2.7V. Like other recent high-end OCZ memory, the DIMMs are warranted up to 3.0V for overclocking. OCZ also tells us that the Rev. 2 memory will run at CAS2 at DDR400, just like the original 3700 Gold. One of our concerns in testing the Rev. 2 was whether or not the memory could possibly reach the performance timings at 400 to 480 that has made the original 3700 Gold so popular. Our testing confirms that in almost every measurement, 3700 Gold Rev. 2 performs just as well as the original, which is saying quite a bit since our test modules are 512Mb modules compared to the original's 256Mb modules.

OCZ uses the distinctive Gold-colored heatspreader on the PC3700 Gold Rev. 2. When we removed the heatspreader, we found that the chips are labeled OCZ. Since almost every memory manufacturer uses large chip makers to supply their chips, we asked OCZ for the source of the new PC3700 Gold Rev. 2 chips. We were told that the blanks are provided to OCZ specifications by ProMOS, a large Taiwanese memory chip supplier that is a division of Mosel. OCZ states that the chips are supplied as blanks to their specifications, and that they are further speed-binned and labeled as OCZ after testing at their facility. The ProMOS chips are used in several other OCZ products depending on the speed-bin ratings that the chips achieve.

OCZ also included a Case Badge in the package for those who want to advertise that they are using top OCZ memory in their computer. This has been included in all recent OCZ packaging.

    And I just received my 3700 Gold rev2, thanks for a happy New Year :-D

    Thanks again wesley for keeping us up to date on the memory front. It does seem though as if this is more of the same. My 2.6c goes up to 246Mhz on default voltage (1.525V) and scrapes 260 even with a .2V boost. At present I run it at 2.8GHz(216) with 1:1 tight memory settings(OCZ platinum 3200) and agressive PAT. I find this gives me almost the same performance as running at 3.2GHz (246)at mem.5:4 with the same tight memory settings (3dmark03 6200 vs 6300). Graphics board memory is under 3ns and two sticks of fast memory costs as much as a good 256Mb video card.So by now DDR500 CAS 2 DDRAM should be out there and is what i'm waiting for as the first upgrade to my rig.

    Also what about 1GBt modules, the i875 has 4 DIMMS and handles up to 4Gb. CORSAIR have been the only ones to announce DDR500 capable 1GBt modules but at CAS3 settings. It would also be good to see how a RAM maxed i875 board performs in particular in the unbuffered tests.

    Even though I'm quite happy with your intel based testing, it would be nice to see how the a64s(even the A-XP) and the FX51 fare in your tests particularly with different memory timings. The FX51 beats the P4 in many memory bandwidth tests but I'd like to see if this occurs in the unbuffered Sandra and Memtest-86 tests.
