MRS is a setting within the ram that's set by reading from a certain location while the northbridge is in MRS mode. It essentially tells the ram what timings to run at. For the most part, the only values you'll ever need for SDRAM are 0x1d0 for CL3 and 0x150 for CL2, but DDR and DDR2 make more advanced use of MRS and E(xtended)MRS. Read the JEDEC standard for more info.
What do you mean by this??
And just realized something else, directly related to the email I just sent for Joe. Please change the MRS value from 0x1d0 to 0xad0. Heh, that could seriously bork things up, my bad.

What am I supposed to use for CL3?
Thanks - Joe
