EVGA nF4 Motherboard Problem

[MisterK]

I have been told that the Jetway board and the EVGA board I have are pretty much the same thing, and Anandtech had reviewed the Jetway board and used OCZ Platinum Rev.2 RAM.

However, I have my EVGA board, a 7800GT, and the same OCZ Platinum Rev.2 RAM and the board is having massive problems with it. These are the problems I've noticed:

1. RAM is clocked at half of its rated speed (Its supposed to be 400mhz, not 200)
2. The timings are way off.
3. Its running on 2T command rate
4. Its not showing up in the right slots in CPU-z. I have it in slot 1 and 3 and it shows as being in 1 and 2.

If I try to change the mhz on the RAM to be 400 like it should be, it won't even boot up and I need to reset the BIOS.

If I change the command rate to 1T I can't boot into windows and just blue screen on the way in.

If I change timings the same thing happens.

Anyone have any ideas? I've tried other RAM on the board and it is extremely unstable and it will crash when I'm loading things like games.

Make sure you're looking at the right settins & the settings right. Sounds like you may be doing one helluva overclock all at once. DDR ram is figured x2, 200 x 2 = 400.

Dual channel needs to have a Matched pair. The specs you have here don't appear to be.

 

[MisterK]

It IS a Dual Channel matched kit, its just not showing up as one. Its an OCZ Platinum Rev.2 kit.

make sure you have them in the "correct" ram slots, evga put up a re-write for their manuals because the ram section was written incorrectly!! ill see if i can find a link and edit it on this message...

notice the text in red on page 13(on the page) which is page 14/38 in adobe acrobat heh

 

[MisterK]

Yes, the RAM is in slots 1 and 3 but shows up 1 and 2. I've tried it in 2 and 4 as well.

 

[whatmeworry]

I have mine in 1 and 3 and CPUID it shows 1 and 2.
I have the same board. My memory shows correct at 200 though. I am using 2 sticks of Patriot 512mb

I have the same problem, the RAM running on 2T command rate, if I change the command rate to 1T, no boot, does anyone know how to fix this? I have OCZ Gold VX PC4000, thanks.

eVGA is well aware of RAM incompatability issues.

This should help you out some.
