I ordered around 10am, received it just after noon the next day. First order of business, fill out the rebate stuff (I've missed so many rebates because I neglected to do them, probably $100 worth in the past year), make photocopies of all the stuff and drop it in the mail.
Package says Kingston ValueRAM, PC100 CL2. Chips say Samsung on them. I have a system with an Abit BX133-RAID running a P3-700 OC to 933. I removed the Mushkin RAM from it, and put in the new stick. Running at 133MHz, 3-3-3. Stable. Have not tried messing with it yet, to see if it runs 2-2-2 or any combination of 2 or 3. I don't really expect it to, because I had a PC100 stick that used Samsung chips which can run at 140MHz 3-3-3, but can't do more than about 105 at 2-2-2.
I'm gonna give the extra stick of 256MB to my GF, take her old 64 and 128 out and use that to upgrade her parent's machine to 128 (from 64, so I can play Unreal Tournament on it better when I visit) and still have 128MB left over for upgrading other machines.
