Performance Comparisons
Performance of the PMI DDR533 Gold was compared to all of the memory recently tested in:Samsung PC3700: DDR466 Memory for the Masses
Kingmax Hardcore Memory: Tiny BGA Reaches For Top Speed
New Memory Highs: Corsair and OCZ Introduce DDR550
OCZ PC3700 Gold Rev. 2: The Universal Soldier
OCZ 4200EL: Tops in Memory Performance
Mushkin PC4000 High Performance: DDR500 PLUS
Corsair TwinX1024-4000 PRO: Improving DDR500 Performance
Mushkin & Adata: 2 for the Fast-Timings Lane
Searching for the Memory Holy Grail - - Part 2
Memory performance was compared at DDR400, DDR500 and the highest stable overclock we could achieve that would run Gun Metal 2 Benchmark 2, Quake 3, UT2003, and Super PI to 2MM places. Where the data was available, comparisons were also made at DDR53.
Results are compared for Quake 3, Sandra UNBufferred Memory Test, and Super PI. SiSoft Sandra 2004 reports 2 results for each memory test - an Integer value and a Float value. Results reported in our charts are the result of averaging the INT and FLOAT scores, which are normally close in value. In other words, INT and FLOAT scores were added and divided by 2 for our reported score.

[q]Why is my dinghy smaller after I go swimming? Why cant I buy pork boullion? Why cant I buy toast in the store?[/q]I too would like to know! Damnit, wes, Stop witholding information from the public!

color, color, color. Did I mention that I'm a sociopathic liar?bldkc - Friday, March 26, 2004 - link
You may have told us before about the inability of the software to change the color, but I missed it. Thank you for doing so again. I am aware of the stratospheric bandwidth usage at Anand, and that is because you guys rock. Thanks for the excellent articles, and keep up the good work Wesley. I won't mention the colors again.Visual - Friday, March 26, 2004 - link
The graphs really could use some colour coding though.Wesley Fink - Thursday, March 25, 2004 - link
TrogdorJW -The flash charts are much smaller than JPEG would be but I don't have any numbers to share. Email Jason Clark, who does our IT reviews, and I'm sure he can give you some idea of the bandwidth savings.

Damn, Wesley... this is the first I've heard of this, and after looking back at the charts, I am only now discovering that you use Flash files for the graphs. Cool! I'm guessing that there's a Java application that is used to generate the graphs from some spreadsheet? Or are all the graphs generated in real time? Meaning, if there were an error in a graph, like a misplaced decimal or something, could you simply update the spreadsheet, or do you have to run the Java Graph utility as well? Either way, that's pretty friggin' cool. But then, I'm a programmer geek and like seeing such uses of technology.If you don't mind answering, how large are the generated graph files? I would guess that in JPEG format they would be on the order of 30-50K each. What sort of savings do you get out of this?
Anyway, back to the memory being tested here. After the results not too long ago showing that low latency DDR400 timings with a 5:4 ratio on a P4 resulted in similar performance to 1:1 ration and higher timings, I really don't see much need for these "faster" DIMMs right now. My Mushkin can run 2-3-2-6 at PC3200, which is pretty close to the top. Seems like I can just run the system bus faster while keeping the memory bus at 400 MHz (200 MHz, actually) and still get similar performance. Or is that only the case with P4 systems?

Probably PMI and OCZ go through the same manfacture like Dell or Alienware Laptops aren't really design by them. They just buy laptops from Clevo or Compro and retag their names on them. Creative Labs and PNY video card are retaged MSI cards. The only thing I see PMI copying is the packaging, if the price is lower then OCZ I would buy PMI.RuStYwAvE - Thursday, March 25, 2004 - link

They're never going to make it. Not with a name like Pmi and a logo with nice rounded letters and a halo(?) around the 'i'. With all the big companies as close as they are at the top why would you buy this when you could have cool looking names like "HyperX" or "OCZ" on your memory?Ok, I'm just kidding. It's weird how there's suddenly so much memory that is so close right around the top. I bet pricing plays the biggest factor in their success.

Go on wesley, now that you're off the beaten track, get hold of some of that 2-3-3-6 Xtreme DDR PC3700+ (http://www.xtremeddr.com/products/x_pc3700+.shtml) and tell me if it is any good.
