corsair in post 5 here seems to be ok. dividr puts the ram ~225 but its 1t.
as a rule the corsair vs is tough but it runs, especially at stock. my ocz3500 was the same, well worse actually. i could get 220 and not a bit more out of it. it ran fine a stock but not an oc to speak of.
the rev 2 fixed that up for me 😉
the vx is nice but i'm not a fan of the volts you need to make it shine.

That's very intersting, because that's also exactly what my Gigabyte K8NS does. The motherboard automatically detects the timings as 2.5-3-3-7, which are unstable. I though my RAM was defective (first build) when I installed it (ran memtest before installing windows), luckily I knew about memory timings, and relaxed them, until I found stability at 2.5-3-3-8. I thought this was a problem with my mobo, but it seems it isn't as yours is doing the exact same thing. I would get errors all over the place when I ran x86memtest though. The SPD on the ram might be programed with incorrect timings, since both our boards are detecting exactly the same unstable values. Also, the mobo won't post with the ram (2x512) at 200Mhz, 2T or 1T, even with 2.7 volts VDIMM, although I'm pretty sure it's an issue with the memory controller on the CPU (it runs fine with one stick at 200Mhz 1T at default voltage). I can get both sticks running at 166Mhz 2.5-3-3-8 1T though. You might try downclocking to get 1T, as Zebo's threads have shown that it's the only memory setting that really makes a "big" (5%-10%) difference in real-world tests on the Athon 64.

BTW, does anybody have this 2 DIMMs of this ram running at 1T at 200Mhz?

Thanks for the info, the DFI forums are excellent.
I have that exact same mobo + RAM. There is an issue with Corsair + DFI and DFI themselves are aware of this. Their latest BIOS update attempts to fix it. To get Corsair VS to run stably requires overvolting the Vdimm. I myself have not tried the new BIOS so I can't say for sure whether this fixes it. However, I am currently running my RAM @ 2.9V which doesn't void warranty according to the RAM guy on Corsair's Forum.
I'd suggest either downloading the new BIOS and see how things go or just overvolt the RAM until the RAM is stable (but don't go above 2.9V unless you don't mind voiding your warranty). Good luck!

Actualy there isnt that much of a difference.
Have a look at this thread that Zebo started a while back.

this corsair issue is true for the SLI and ultra D boards, its unfortunate. its the NF4 + DFI more specifically that causes this problem.
but its not that any DFI cant use corsair, NF3 chipset has no problem, i use value select with nf3.

Yeah, I'm having no problems wiht my LanParty 865PE board and Corsair value ram.

Exactly, VX is not the most user freindly RAM out there! After a week of staring at memtest screens and posting in the OCZ support forums, I finally got my OCZ PC4000VX to its advertised speed of DDR500 @ 2-2-2. It runs this at 3.2Volts without active cooling. The ram needs a burn in period of a few days at first of 3.4 volts or so. After the burn in period it works at its rated speed. This ram is crazy! VX is probably not for everyone. Unless you are willing to spend some time tweaking BIOS settings and looking at memtest screens for days, get some TCCD.

well, you'd never guess its old news based on the amount of people who don't use it yet recommend it to people who have no idea about the extra volts and cooling needed. not to mention the burn in.
the "official bf2 buyers guide" recommends it for new builders who want to "game into the night".
it ain't for me thats for sure, i'll take my rev2 anyday.

I think BouZouki was refering to the OP and the Corsair RAM being "old news". But yes you are correct, VX ram takes A LOT of tweaking. People that follow others recommendations about this RAM, think that the RAM will work right out of the box, and they will likely be dissapointed.
I was almost going to RMA this RAM before I finally got it to perform. See the OCZ support forums for getting the most out of your VX RAM.
Yea, I was regarding the CS VS ram not the VX.
Either way, my opinion on the ValueVX,
Its not for idiots who dont know what they're doing (Someone who has never oced anything in their life)
If you know what your doing, value vx is the best thing to hit the market since bh-5.

Corsair Value can be made to work with DFI NF4 by adjusting the little timings and using the correct bios. They reach in the ballpark of 233 MHz 6-3-3-2.5 1T at 2.6V
