cl2 @111 or cl3 @ 148

the subject says it all really, which is more important, cas latency or mhz, just got a new stick of crucial 133 cl2 to make 512 total, one ran fine @ cl2 148 but two will not without moe v, of which I cannot do with my VH6-II, so what will be faster for me.

Also one more unrelated question, I just setup my first FTP server, and found that while my tweeked downstream can get me downloads of 200+kbs. My upstream won't go past 36kbs, this would be fine if it were just one user but 3 or 4 @ a time trying to DL files as large as 1.9gb (yes I ment gb not mb) that can take a long time. Can anything be done to get more out of my upstream

Run Sis Soft Sandra 2001 Benchmarks on your system to see which setting give you the best overall performance.
Maybe even try 3DMark 2001 w/ directX 8.xx?
See what your best settings are and go with those.

Good Luck.
