Adata PC4000
Click the image to view a larger picture.
Adata DDR500 is a very reasonably-priced DDR500, but somewhat difficult to find in the US market. It is readily available and widely used in many Asian markets. It was the only DDR500 tested in this roundup which was not supplied as a Dual-Channel kit. The DIMMs are packaged without heatspreaders, and labeled are assembled from blanks that carry an Adata ID.
The Adata performed well at DDR500, but our samples were some of the poorer overclockers in our DDR500 roundup.

I am tired of setting the memory timing and bench mark all the time. Is there a program there which can tell me what kind of results I would get? Say if I can increase my CPU by 5 MHz but have to set back my memory timing a bit, which way should I go?oldfart - Thursday, August 28, 2003 - link
Here are some reviews comparing tight timings Vs loose:http://www.hardtecs4u.com/reviews/2003/ddr400_roun... (need language translator)

I think this was an extremely helpful and thorough review. There was one comparison, though, that I would find most helpful and haven't found anywhere. I'm currently debating the importance of running synchronously, and thus found the section "Does memory speed really matter in the real world" extremely interesting. However, I would have greatly preferred one additional test -- running 1066FSB at 3:2 and 5:4 with memory with tight timings (2-2-2-5), since my real debate is whether to buy PC3200 or PC3500 with tight timings and run at 5:4 or 3:2, or PC4000 with loose timings and run at 1:1. While I expect that the synchronous memory would result in better performance, I'd really like to know how much better, since PC4000 memory is expensive!Thanks,
Steve

Great Review Wes. Keep Em coming. I am not "PAID" to say this either. I wanted to. I am getting nothing for it either. Just the satisfaction of telling Wes I loved his review.Anonymous User - Thursday, August 28, 2003 - link
Great review Wesley. Nah I'm not paid to say this, I just enjoyed the review!Anonymous User - Thursday, August 28, 2003 - link
I have tested Kingston HyperX RAM at 1:1 3-4-4-8 @ DDR500, and 5:4 2-2-2-5 @ DDR400 at the same FSBs on a P4P800, with MAM Enabled and Turbo performance mode in both cases. While the 1:1 gets about 3-5% better Sandra bandwidth scores (buffered and unbuffered), SuperPI completes about 1.5% sooner at the 5:4 settings.So real-world performance may be slightly better at 5:4, but you won't win any Sandra bragging rights with it.

Wow, looks I'm not the only guy who wants to see250 FSB
1:1 3-4-4-8
5:4 2-2-2-6
type of testing. I've seen several reviews that show the lower latency ram @ 5:4 to be faster.
Part 3??

Hey Wesley,Thanks for all the good info...
Any chance you could test Various FSB's
5:4 2-2-2-5 vs the same FSB at 1:1 2.5-4-4-7
It would be great to show the readers how the new PC4000 REALLY compares to older slower low latency RAM, Mushkin PC3500 level2 would be perfect for that.
Now that would be a seriously good Anandtech caliber review. :D

#32 and #40 -Mushkin did not have a product in our hands when the review was done. In fact I completed a review of Mushkin PC3500 Level II just a couple of days ago, and compared it's performance to ALL the memory in this review at DDR400. I also tested Adata DDR450, which did not meet our requirement of running at DDR500, but DID perform well at DDR400.
The reviews should be up here shortly. The Mushkin did VERY well at DDR400 to DDR450. Mushkin is also about to release DDR500 - but they did not have a product ready in time for our review. We WILL be testing it as soon as it is available if time allows.
