RAM question

[SecondShadow]

Alright, I just got my 256MB CL2 PC133 SDRAM in the mail today and I've been mucking around with the SDRAM timing settings a little. My first question is what can I use as a good stability test to make sure that my computer isn't going to do something wierd while in the middle of something like, oh I dunno, after almost completing my programming assignemt for class it crashes. That would not make me happy.

My other question is about the settings themselves. More or less I would like to know which ones are generally speaking safe to mess with and/or what the optimal settings would be.

Currently the settings are as follows in the order they appear in the BIOS:
SDRAM PH Limit: 32 Cycle
SDRAM Idle Limit: 8 Cycle
SDRAM Trc Value: 6 Cycle
SDRAM Trp Value: 2 Cycle
SDRAM Tras Value: 5 Cycle
SDRAM CAS Latency: 2 Cycle (of course)
SDRAM Trcd Value: 2 Cycle

PS: I just noticed that SiSoft Sandra reports that my memory bus speed is 100MHz. Is this correct? And if so how do I fix it? It should say 133MHz right? RAM settings aren't my forte as you can tell.

Ram runs at the same frequency as the system bus runs. If you are running your mainboard at 100 mhz, the ram will also run at 100 mhz. If you can run your cpu and board at 133 mhz fsb, then the ram will run at 133 mhz.

Concerning ram timing settings you ask for, I do not know myself, as I have very little experience doing that myself...someone else will hopefully come by with some answers for you.
