Please help me to configure my ram (TCCC)

[MorLipf]

Hi,

 

I own 2x 512MB Corsair XMS Twinx PC4000 with TCCC chips. The only thing I want is to get it stable at 400MHz and it's default timings 3-3-3-8-1t. The voltage is set to 2,8V.

 

If I test each ram separately it don't get any error in Memtest86+. But in dual channel I get 11 errors in test #8. Now I've disabled bank interleave and they seem to be stable. But there must be another solution, I don't want to decrease my memory bandwidths.

 

I've tested the following bios versions without succes: 623-3 (the current version I've flashed), 702-1. 702-2.

 

Do you can help me to configure my ram?

Edit: Now it seems stable with bank interleave = enable. What's going on with my board / ram? This can't be a normal behaviour.

Also clear the CMOS for 10 minutes.

Thanks, I will try it. A few minutes ago I tested the ram in memtest without errors. After that I disabled memtest and switched my computer off. But I couldn't turn it on again. I got a black screen and no beep noises. So I cleared the CMOS and then it booted.

 

Yesterday I turned it off and removed the power cord over night. This morning my SoundBlaster wasn't recognised anylonger.

 

Is this in conjunction with the problems I've written down above?

The SB thing might be due to you flashing the BIOS/not clearing the CMOS for long enough.

 

When you flash the BIOS the IRQs can change and effect windows.

Also if you dont clear the CMOS after the BIOS flash it may do some odd things.

 

Always clear the CMOS for 10 minutes.

And never load any CMOS RELOADED profiles from a previous BIOS version.

 

Or if you did not disable the Karajan audio module it might be using that as the default Sound device. (maybe )

My ram is not stable over 2.7volts. Always start at the lowest setting and increases as needed only. dont start at 2.8 for stock speeds.

My ram seems stable now with 2,8V. And now I think I have an idea why the SoundBlaster was not working properly. It shares the IRQ with the video card. Maybe that causes my blue screen in 3DMark.
