You have to look it up at the manufacturers website.

Rick, this is for CPU's. I don't see how it will give you the CAS latency numbers for your RAM.

Hmm, maybe. I myself am actually not very interested in the CAS latency numbers for my systems. It does not buy me anything knowing that. It is what it is. I know it is usually between 4 and 6. But that is not very telling. You need a lot more info to usefully apply the number. Would be different if I were out shopping for Dimms.

You are both right! It is best to get your CL and other timings and voltages from the manufacturer, if you can. Also, it's not that useful to have the numbers for your installed memory, because there is not much you can do to change it.

However, CPU-Z does have a very cool feature on the "SPD" tab that reads the JEDEC timing tables from the DIMMs. This information is useful when first setting up a new build-your-own system because the default timings may not be the best for your build. The "Memory" tab in CPU-Z shows the current timing settings.

EDIT: and, BTW, CPU-Z can also show you the manufacturer's name and model number of the DIMMs (SPD tab) which will save you from opening your system to read the tiny print on the DIMMs themselves.

so i just download the thing rick's telling me?

Chris, This will be a Zip folder. You unzip it and double click on "cpuz.exe". That will give you the data - after a couple of minutes. Then click on the "memory tab" where you'll find your CAS Latency. I don't know though what you are going to do with the data - other than look at it.

Rick, I know what it means to you. But I was wondering what it means to Chris (whom I know since a long time).

Rick, if you want to do some "historic" reading.

Ya,Ya

Chris, you may ask as many questions as you want. No problem. But you must also read the answers - 3 times if neccessary.
Btw: With what PC did you finally end up?
