Problem: Timings.

post #1 of 4
Thread Starter 
Had a deeper look into the BIOS today, pulled out the Memory timings page and decided to tweak it.
I've had no problems with raising the FSB, but I kind of hit a snag when attempting to tighten my timings...
Stuck the CAS Latencie at 2, and left the rest stock...
Stupid Idea?
Failed to load the BIOS upon restart, so I guess I did something wrong...
(Thank God for the CMOS button on the MSI )
Thanks guys.

Usually DDR2 won't run at a CAS2. If you want to try for it, try bumping you're Vdimm to 2.0v if it's at stock. I wouldn't go much past that unless it has a heat spreader on it. If you want to keep your FSB as high as you can, which is recommended for Intel CPUs, reduce the CAS to 3 and keep moving your FSB up.

Thanks
I followed your advice, and realised that I can get the sytem to run when the CAS is lowered to 3, but I can't increase the FSB anywhere near us much...
What's better? High FSB and stock Memory timings, or Lower FSB and tighter timings...
Unless there isn't a generic answer, in which case, time to get used to the CMOS button!

For Intel's higher FSB is preferred since the core speed is high compared to their AMD counterparts. So the more FSB you can give it the better.

AMD's however since they perform 9ops/sec they perfer tighter timings to access their data quicker.
