Weird computer post error

[Nick89]

Well, when I start my comp I get this error at the bottom of the screen

DQS En pass window CHA to CH B too large
Press F1 to resume

I press F1 and the comp boots perfectly, this error only started today and I've had Win7 installed for 3-4 days other wise I never had it when XP was installed.

I remember when I booted my system the other day it froze when it said checking NVRAM or something so I held the power button down to turn it off and then I think that is when it started saying that. Usually it only says checking nvram for a half second then it goes to the windows boot screen.

Has to do with your memory and the motherboard bios. Have you tried clear the cmos? If yes, Try reflashing with the latest bios.

Intel's take on the subject:

"Problem: The valid data eye is wider than anticipated in some configurations. In these cases, the DQS sample
data from the DCALDATA register measured during the DQS calibration portion of memory
initialization may contain all 1's before finding the left edge of the eye.

Implication: This situation makes it impossible to use the data to determine the DQS passband and calibrate the
DQS slave delays.

Workaround: The BIOS should set the affected DQSOFCS.DQS offset to 0h. In addition,
DRAMISCTL.CH0SLVLEN should be set to 100b for DDR and 011b for DDR2, guaranteeing a
sufficient DQS window. The Memory Reference Code revision 0.52 implements this workaround.
See the Twin Castle BIOS Specification Update for more details.

Status: There are no plans to fix this erratum.

I can't find anything @ foxconn.

You can google "Bios DQS" for info.

I found this and they are into it:http://www.xtremesystems.org/forums/showthread.php?t=57925&highlight=DQS

While reading the reviews at Newegg, I found one where the person was talking about enabling access to all the ram in bios and having to install one stick at a time and re-booting when he went to 64 bit OS.

Hope this helps.

Its weird cause I have this error still but I have no problems what-so-ever.

I have 4GB ram installed(x4 1GB sticks) and they are all running at 501mhz 5-5-5-15, 2.1v

I have the ram set for stability.
