Test Results : Patriot PC3200+XBLK
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 particularly Super PI, will crash a less-than stable memory configuration.| Patriot PC3200+XBLK (DDR400/533) - 2 x 512Mb Double-Bank | |||||||

In rows 1 to 5, CPU speed is kept at 2.4GHZ and only the Memory Speed is varied. The performance differences you see in that range are a result of Memory Speed and memory timings only.
We have looked at Aida 32 results in the past, and found them 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.

While maintaining a constant CPU Speed of 2.4GHz, we measured the impact of increasing the Memory Speed from 200 to 300, a 50% increase. Memory Read performance increased about 29% with this 50% speed increase, while Memory Write performance improved by just 17%. Latency showed a reduction or speedup of about 12%. With any TCCD memory, Memory Read/Write/Latency benchmarks are also impacted by the slower memory timings required at higher speeds.

I just got this ram for my nforce2 system :DAuric - Monday, April 11, 2005 - link
Article seems to imply these are new but they have been available since last Autumn. Also, they are tested at five performance ratings, not two, which eliminates much of the messin' when overclocking the FSB/CPU.http://www.pdpsys.com/products/PDC1G512G3200+XBLK....

Dear Wesley Fink, May I know the memory timing used for PDP at highest performance 315, i.e. tRFC, tRRD, tWR,tWTR, tRTW, tREF, DQS, Drive strenght ect. If it is set to Auto, could you please read the value with Athlon64 Tweaker? :-) Does 315MHz 1:1 passed memtest test 8 and prime95 stress test? This is because I am running PDP stable at 289MHz, 3.0-4-4-10 Thanks.KayKay - Friday, April 8, 2005 - link
Any idea if this product is sold in Canada? I really like the balance of value and performance.Wesley Fink - Friday, April 8, 2005 - link
#16 - It is XBLK as you found, and the article has been updated. My tests for dyslexia are next week :-)ozzimark - Friday, April 8, 2005 - link
It brought a tear to my eye that you guys have already gotten the Everest benchmarks worked into the review. :)though, out of curiosity, do you plan to go back with the ram you tested previously on the dfi and add the everest scores to them? i'm sure it'll take up quite a bit of time though :/
sonicDivx - Friday, April 8, 2005 - link
XBLK is what it is.I currently use it an hit the following stable.
MBD: MSI NEO2
Memory: 280 2.5-3-4-7 2.8v 1:1 ratio
Wish had the DFI board I think with 2.9 I could hit 290. I have hit 282 with 2.5-4-4 2.85v but that is really the limit. with my NEO2.
Its nice memory, when I purchased had gotten it for 186 :)
wildguy2k - Friday, April 8, 2005 - link
Dunno if there are 2 different kinds, but throughout the article, you refer to it as XLBK, & the only results I can find price-wise are for XBLK. FYI.Wesley Fink - Friday, April 8, 2005 - link
#9 - The unique appearance of the back of the Brainpower PCB is much clearer in the p.2 photo in our Corsair PC4400 review at http://www.anandtech.com/memory/showdoc.aspx?i=231...OR you can direct link the Corsair Brainpower photo at http://images.anandtech.com/reviews/memory/ddr/cor...

#11 - It should read "Memory Read performance increased about 29% with this 50% speed increase, while Memory Write performance improved by just 17%."The review has been corrected.
#13 - It depends on which Kingston you are talking about. We include two Kingston Value Ram products in next week's Value RAM Roundup.
