Test Results: Corsair XMS4404v1.1
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 in particular Super PI, will crash a less-than stable memory configuration.| Corsair XMS4404v1.1 (DDR550) - 2x512Mb Double-Bank | |||||||

Corsair was reviewed in Corsair 4400C25: Taking Samsung TCCD to New Heights. It is very interesting to see that the DFI board opens up performance of the Corsair a bit more, allowing use to reach a high of 303 (DDR606) at 1T compared to the 295 (DDR590) top 1T performance in the past review. However, the fastest performance was achieved at 10x280 at faster memory timings of 2.5-4-3-6 and a higher CPU speed of 2.8GHz.
Corsair selected Samsung TCCD chips for absolute best performance at the top and they succeeded in reaching this goal. The compromise was a bit less performance at DDR400 - at least with the modules that we tested. However, we suspect that the timings used by DFI are not the best match to this Corsair memory, since regular TCCD memory rated at DDR400 outperforms the Corsair at the top - results that are the opposite of what we have seen on other nVidia chipset boards. It looks as if Corsair and DFI could squeeze more performance from this combination with some tweaking.
It is interesting in these test results that the faster 9x303 (2.73GHz) cannot match OCZ VX at 2.67GHz. However, at 2.8GHz (10x280), the Corsair TCCD can roughly match performance of VX at 2.67GHz. It is clear that faster 2-2-2 memory timings of the OCZ VX do matter when it comes to performance.

#9 - We reran everything in this review and took nothing for granted. Both results are the result of memtest86 on different BIOS, and a different pair of Platinum Rev. 3. I would guess the later BIOS is the difference. You can easily run the test yourself to check for best bandwidth, but 6 is the recomendation with this setup.#12 & #13 - You forgot that MSI won our nF3 Gold award and was our nF3 board of choice. The MSI also shared as the nF4 winner. With so many brands being pimped, it's hard to keep up :) We like the best performance - regardless of brand.

"anandtech is the biggest dfi propaganda site on the web"I noticed that too.... but is it possibly due to the fact that their nf4 board is so much better than everybody else's??
just like this memory is suprisingly better than the competition
I guess what they are saying may be you are crazy to buy anything else for the same price.... however not everybody can affor a dfi nf4, 6800ultra sli + 1gb ocz vx memory

i should say, before they were the biggest asus propaganda site, but tons of early problems with the sli have quieted them latelyarswihart - Wednesday, March 30, 2005 - link
anandtech is the biggest dfi propaganda site on the web, where's the attention to all the other nf4 boards?bigtoe36 - Wednesday, March 30, 2005 - link
#6 there is always value VX if you don't want the warranty to 250fsb etc, you pays your money you take your choice.PhoenixOrion - Wednesday, March 30, 2005 - link
what kind of cooling on the cpu for the test config?Viper4185 - Wednesday, March 30, 2005 - link
Nice follow up article but there has to be a mistake somewhere on this page...http://www.anandtech.com/memory/showdoc.aspx?i=238...
First you say this...
"In the SLI roundup, we found a tRAS of 7 to be ideal for memory based on Samsung TCCD chips."
Then...
Therefore, a tRAS setting of 6 was used for testing wherever possible.
I refer you to this article...
http://www.anandtech.com/cpuchipsets/showdoc.aspx?...
It says 7 here??? So which is best 6 or 7?

It would be nice to see some overall overclocking performances, using the FX-55 to see what the highest overclock you can gain is (obviously concentrating on the top memories).ie: If the VX was using with an overclocked FX55, how would it compare at max speed other RAM and the same CPU?

Waste money on a hyped brand name? Or save $100 or Save $100 with "Twinmos speed premium"... Your choice and google is your friend:)
