I bought mine from newegg when it was $77 and crucial PC2100 was $72. To be blunt, it's crap. It runs great at 133MHx/CAS2, but it won't run at anything higher, even if you set it to CAS2.5 or CAS3. I've tested this in a mobo with asynchronous CPU/Memory settings, too, so I'm sure of it. Mine came with 7ns chips. Newegg told me "they didnt advertise ns ratings" and "would replace with another of the same product" when I asked them about it. Which is BS, because it says 5ns and "true PC2700" in their pricewatch ad. I came on here and asked for advice, but I was told to suck it up, so that's what I'm going to do.... eventually I'll RMA to kingmax, if they ever decide to put a real website up...
in short: kingmax is suck, stay away.
