Transcend JM366D643A-50
Transcend will be best known to some of our readers as a manufacturer of flash memory. While flash memory is an important product line for Transcend, they also manufacture storage products and system memory. You will not find Transcend for sale at a huge number of US websites, but Transcend also sells directly to end-users at their website. Transcend has US sites in both Spanish and English, as well as several European language sites, and Taiwan, Japan and China websites.
Specifications
Transcend rates JM366D643A-50 at DDR400 CAS 2.5 and we found the "auto" or SPD timings to be 2.5-3-3-8.| Transcend JM366D643A-50 (DDR400) Memory Specifications | |

512 MB 1GB |
| Rated Timings | 2.5-3-3 |
| SPD (Auto) Timings | 2.5-3-3-8 |

Transcend shows both DDR400 CAS 2.5 and DDR400 CAS 3 in their product list, so it is clear that the DIMM products from Transcend are aimed at the Value end of the memory market.

Transcend is another memory that costs just $100 for a Gigabyte and yet manages to nearly reach DDR450 in overclocking. The cost and performance are very similar to the Kingston CAS 3 rated Value RAM except that Transcend rates its Value RAM at CAS 2.5. While the rated timings differ, both Kingston and Transcend both are stable at CAS 2.5 at DDR400. The Transcend RAM is an excellent value and provides the overclocking capabilities to reach a 12% CPU overclock at 1:1 memory ratio.
We have looked at Aida 32 results in the past, and found them to be very useful in examining read/write performance and memory latency. Aida 32 is now available as Everest Home Edition, a free download from www.lavalys.com.

It is easy to see in the Everest results that dropping CAS just from 2.5 to 3 in moving from DDR400 to DDR436 offsets virtually all of the performance improvements that you get from higher memory speed. The $100 Transcend reaches on to DDR446 to give you most of the headroom that you need for air-cooled 1:1 overclocking at stock multipliers.

1 GB (2 x 512 MB) of Crucial Ballistix PC 3200 now lists for $192 U.S. at crucial.com.On any mobo, it runs at 200 MHz (DDR 400) at 2-2-2-6 timings at 2.8 V, outperforming any other RAM in this review.
As shown by AnandTech (www.anandtech.com/memory/showdoc.aspx?i=2386), on a DFI nF4 mobo, it overclocks to 280 MHz (DDR 560) at 2.5-3-3-6 timings at only 2.9 V, where it closely matches the top performance of any RAM available at any price, bar none. IMHO, this is real value.
Adding a Venice 3200+ overclocked to 10 x 280 MHz = 2.80 GHz (www.xbitlabs.com/articles/cpu/display/athlon64-venice.html), a Thermalright XP-90 heatsink with a SilenX 92mm 14dBA fan, a Seagate 7200.8 SATA NCQ hard drive, and a Gigabyte X800 XL video card with SilentPipe cooling (GV-RX80L256V), in an Antec Performance One (P160) case (www.anandtech.com/casecooling/showdoc.aspx?i=2346) with an XG Magnum 500W heatpipe PSU (available later this month, according to www.xgbox.com), you have the makings of an ultra-quiet gaming rig with near state-of-the-art performance at a great bang-for-the-buck price.

you can. i'm a big advocate of crucial ballistixspeaking of that company, why were they missing from the testing too?

195 seems a bit steep for value RAM. I'd like to point out that you can get Ballistix from Crucial for less than 210 I believe.Den - Thursday, April 14, 2005 - link
Thanks for pointing out that the part numbers are on page two. As many others have said, it would have been really nice to see the best the different rams would do at 2.9v in addition to what they would do with DFI voltage. Also it would have been nice to see a greater range of memory tested but I understand you are limited by not being able to afford to buy and test what you want. Beggars can't be choosy. Thanks for doing this though, the general concept was good and there was some interesting information.NXIL - Thursday, April 14, 2005 - link
Paying $100 to buy some Corsair Valueram (Newegg--had an $88 special yesterday) would have been the fair and reasonable course of action.Consumer Reports has been testing products fairly for decades--they don't accept advertising, and, they buy the cars, electronics, and other items they test anonymously. Of note is that "Sharper Image" has sued them recently (SI lost) when they tested one of their bogus "air purifiers"--seems to make the air less clean, actually, by releasing ozone.
Anandtech should get some Corsair RAM and test it--and, they should buy samples of the other brands tested, and compare the "off the street" samples with the ones provided by the manufacturers. Unless I am mistaken, video card makers were found to be rigging their drivers to test better with certain benchmarks. It would not be too surprising to find that memory manufacturers had taken some of their special high cost "binned" chips and sent them out with a "value" label on them.

Oh dear ... I left this review for 2 days till I had time to read it properly, I'm sorry to say I wish I had not bothered.1) Should have been titled value ram from non value companies. Wheres the real value ram?
Since the price began to drop we seem to be up to our ears in stuff ive never heard of purporting to be cas3@3200 - Stupid me for thinking that thats what a value roundup should include, noname oem kit, not some hand selected bunch of good-but-value-priced ram from the majors.
2) Why is the following question being avoided and ignored? Namely why wasnt any corsair memory got from another source and included in the test?
A reader posted some assumptions however further to that it could be i) they use pretty much the same chips all over and dont want to give the game away that the extra $100 doesnt get you much increase and ii) anandtech dont want to bite the hand that feeds so bowed down to the request rather than doing whats right and finding the truth come hell or high water.
Im not usually this negative but I do feel quite let down, sorry.

I think a lot of folks are missing it. I think some people need to look at this way. You would have upgrade your cpu 1-2 speed grades to equal the performance increase that using the VX or BH5 memory would bring. Even at stock speeds. Now yes you need more voltage, but DFI I believe produces the best A64 borads as well as the best athlon XP board, Ultra B, which all are capable of supplying the necessary voltage. You can also use the ddr booster on some boards. Its a great alternative to increase system performance without spending a lot of money. And this is memory that you can grow with for at least a couple of years. I believe AMD said it won't go DDR2 until 2007. Great article, good stuff, and nice to see other ways to bring a performance increase. Nice job Wesleyunclebud - Wednesday, April 13, 2005 - link

The cheap OCZ is faster then the Plat. Rev2 !!! Ain't dat a Bitch!!! >:-(WTF is up with OCZ. shooot.
srstudios - Wednesday, April 13, 2005 - link
Wesley, I hate to be a nag, but now you have both the OCZ PC3200 Gold, and the OCZ PC3200 Premier with the same model number. PC3200 Gold P/NOCZ4001024ELDCGE-Kis correct.
The Premier should be PN- OCZ4001024PDC-K, at least I think that's the correct part. http://www.ocztechnology.com/products/memory/ocz_d...
I have a gig of the 'old' BH-5, Mushkin Black L2 PC3500, do you think they would play nice with this new value BH-5? I don't think I would combine them, just wonder if you guys have any thoughts about it.
