I bought two sticks of 512MB RAM. Everything is compaitable with my computer (IBM ThinkCentre M Series Type 8189) except for one thing it seems like. The RAM stick that came with my desktop is labeled with CL=2.5V where as the ones that I bought are of CL=2.6V. I installed them last night and my computer is detecting them. What I'm wondering is if it's alright to run them like that for an extended period of time? Will it CAUSE any damage or major slowdown that I might not expect?Here's an excerpt from Crucial.com about RAM latency:

"CL=3, CL=2, and CL=2, 2-clock
In our Memory Selector, the CAS latency of our parts is designated with "CL=3," "CL=2," or "CL=2, 2-clock." (You MAY see this written elsewhere as "CL2, etc." or "CAS=2, CAS=3, etc.") CAS latency is the amount of time it takes for your memory to respond to a command. It only affects the initial burst of data. Once data starts flowing, latency has no effect.

Latency is measured in terms of clock cycles. For example, a CL=2 part requires two clock cycles to respond, while a CL=3 part requires three clock cycles. Thus, CL=2 parts complete the initial data access a little more quickly than CL=3 parts. However, a clock CYCLE for a systems with a 100MHz front side bus is only 10 nanoseconds (10 billionths of a second), so you probably won't be able to tell the difference between a CL=2 and a CL=3 part. "

Hope this helps.

You should always buy based on what you need, not try to RETROFIT it after the fact.
