CAS latency

[Whizzkid_amer]

I want to upgarde my memory but i have been asked what OCZ memory i have got and what my case latency is. What is case latency and how do I find out what it is and what memory chip I have in? I have a Abit AN7 motherboard.

It's how fast your case is. Some cases are cheap sheet metal and are very slow, while others are made of exotic materials like titanium and badassium and have incredible latencies.

If you go for the badassium case, make sure it's a black one. The beige ones are all poseurs. :cool:

;) Whizzkid, we're being facetious, of course. I think you mean CAS latency. It's an acronym, but I'll admit I have no idea what it stands for. To find out, take the memory stick out, and look at it. It will tell you on the label the model number and latency numbers, which will look like four numbers seperated by hyphens, like 5-5-5-12 or something like that.

CAS = Column Access Strobe :)

RAS = Row Access Strobe

Thanks its 5-3-3-7.

Hi Whiz,

What is the part number of your ram?

What is the rest of your system?

[Whizzkid_amer]

its OCZ4CO512PH and its AMD athlon xp 3200 2.2ghz

Whiz,

Your modules are rated for 2.5-3-3-7 operation at 200 MHz (DDR400)

The timings are laid out in the order of CAS-Trcd-Trp-Tras so your CAS Latency rating for these modules is 2.5 :)

Hope that helps.
