How to...RAM Latency Settings

[irobot10]

1) How do I check if my system is using the CAS Latency as specified on the memory?

2) Follow up question - How do I change the memory latency/timing settings if found that the system is not using what it is supposed to?

I checked the BIOS the other day but found nothing there that related to memory settings.

(Relevant details - Vista Ultimate 64-bit, ASUS M2N32-SLI-Deluxe, Corsair XMS2 2x1GB & XMS2-DHX 2x2GB both 800MHz rated at 4-4-4-12 @ 2.1V)

Thanks!

Go into Bios (hit <DEL> at POST) ... under Advanced Menu:

"Jumperfree Configuration" -----> AI Tuning ----> Manual

This will give you access to individual voltage controls, including DDR2 Voltage control

Then go back one and select "CPU Configuration" -----> DRAM Configuration ----> Enabled

That should give you access to the timings you're looking for.

You may also want to download Memset. It will allow you to see your timings without going to bios. Some mobos will also allow you to change timings with Memset without going to bios.

CPU-Z is a good tool also if you are checking from the OS.
