i recently bought a asus a7v333, an amd 2200+ and 512mb ddr sdram. problem is, i didn't find tom's hardware until AFTER my purchase and now i'm not sure whether this ram is CL2.0 or CL2.5? it has the mitsubishi logo on the chips, 8 chips per side, and is says "M2S12D30TP" and under that "TAIWAN93699EOM-6" on each chip. i did a search on that first one and it brought me to the mitsubishi site and but i still can't decide whether it is cl2.0 or cl2.5. thanks for any help you can offer.

Thats CL2.5 according to <A HREF="http://www.mitsubishichips.com/data/datasheets/memory/5..." target="_new">this</A>
But don't worry. The performance gain of CL2 isn't very large. You may also verify the cas latency by checking out the settings in your bios. You may even be able to force that RAM to run CL2.

yeah, thats the site... but there are four chips with "M2S12D30TP" there, two of them are CL2.5 and i THINK two of them are CL2.0, right? it doesn't say on the memory whether it is -75, -75L, -10, or -10L. how do we know for sure?

Ok. I assumed your memory was running 133 MHz (DDR266) in that case its CL2.5. If its running 100 MHz (DDR200) its CL2.

*sighs* It really doesn't matter what the sticker or specifications say... Its what the stick will actually do thats important!

Play around with your memory timings and test them out with MEMTEST86. Ideall the hardest memory timings give the best performance.

On the chip??? You mean on the module with a sticker. That kind is usually not written on the chip. Anyway look in the datasheet yourself. That RAM is not rated to run 166 MHz. And as far as i can see, mitsubishi doesnt have any that can. So I think it's running overclocked.
