I just recently updated my comp with PNY pc 133 RAM. 1 Stick of 128 and 1 stick of 64. It has cycle time 7.5 and access time 5.4 ns. But doesn't say anyhting about cas 2 or 3. i treied to use it in cas 2 at 133 Mhz and everything went blank!!! with a sound like its going to die and then i couldn't get it back till I cleared the cmos and got the default setting. Now i am running at cas 3 and 133. Can anyone tell me if PNY memory runs at cas 2 at 133Mhz? One of them has Huyndai(128 Mb one) and other one had infenion 64 Mb) chip.
