This was just what I needed to fix an older machine. It was hard to find the correct type and a plus to be in pairs. Now memory diagnostic passes and windows 7 is stable for the first time. Like playing a country song backwards I got my OS back, my Lan speed back, and my sanity back.

Beware of KINGSTON rebates!Of course, I hope your experience would differ, if you were to buy Kingston product(s), but mine was terrible.I bought a Kingston CompactFlash card that offered a $50 mail-in rebate. I promptly (as in, the day AFTER I received the item delivery) went to photocopy my rebate certificate and UPC code and sales receipt; then sent it all on its merry way. Yes, I was well within the rebate period, both for the purchase AND for the postmark date. My purchase was a valid retailer (think HUGE online e-tailer).The rebate REQUIRED sending THE ENTIRE ORIGINAL UPC label, which was like the entire outside package for my CF card, about the size of 1 ½ business cards when flattened. No problem.About TWO MONTHS later, I get a letter saying "your rebate request was denied because you failed to furnish the appropriate ORIGINAL UPC code as required by the rebate offer."Well, now WHAT? I can't RE-SEND the original (it was already in their possession). I called, and they insisted on repeating what the letter said. I re-sent my PHOTOCOPIES and they said a photocopy is invalid proof of purchase.After another 6 weeks of pursuing this, I figured this is their scam. They simply wouldn't honor the rebate. And without the ORIGINAL UPC in my possession, I couldn't really submit to their requirements.If you're looking for a RAM upgrade, I'd suggest you look at a quality company like OCZ (the BEST!), or Patriot, Geil, or Corsair. If you're looking for a value Flash Memory Card, I might suggest SanDisk.For one, Kingston does NOT make the best products, they are VALUE-driven products.Two, there are competitors to Kingston with just as good or better value-to-performance ratios at the same prices.Three, Kingston will not stand behind their customer as I have experienced.I urge you to, please, be cautious of Kingston and their rebate scams.
