FS: 2 PNY PC133 256MB Dimms - also will work in machines needing PC100 or PC66 memory. 168 pin. PNY backs their memory w/ a lifetime warranty. These two work great - just upgraded to a new MB that only uses DDR, so these are just sitting around. Only used for a couple of months, before my HD died on my old system and I scrapped it. Best price on pricegrabber is for a simgle DIMM $45 shipped. Price: $30 shipped each - or $55 shipped for both. Paypal preferred No, this isn't cheap generic RAM - it's PNY. Warranty is very nice, and I'll guarantee them against DOA. I've got a +6 on a good traders list - going for master trader!!! Thanks! edited - these are 168 pin DIMMs, not 184 as previously posted. Too late for me to be posting, I guess.
