Summary: The CPU arrived on time and look in good shape. The pins had a little debris in there, but I manged to clear it out. I was a little nervous becase of the debris, but once I put in the CPU, it worked beautifully and I noticed the speed increase right away! TLDR: It worked like a charm!
Summary: This processor is very nice, it works very well and it is quite fast. I installed it into a 2004 system that was very slow before, and now is nice and fast. i got it used for 55 dollars, and it was very worth it. If you need a dual core for an old socket 939 system, get this processor.
Not quite a socket 939 4800+ but a great processor for a vintage PC

Summary: Just bought this socket 939 4400+ in late 2013 to upgrade a vintage Compaq Presario SR1920NX. (Actually bought two from different sellers. Both are running in SR1920NXs like champs despite their being so old.) Installation went smooth as silk and the processors have been working nonstop for the past three months or so. The 4400+ dual core processor is a no brainer upgrade for anyone still bogged down by a single core Athlon 64 or Sempron processor.
Summary: it works well for being an older CPU it did what I wanted it to do for an old 939 board and put a bit more life in it. this is not a new processor by any means it does not support the new DDR 3 rams it was for giving a bit more life to an older machine for a nice little price
For it's age, this is an AWESOME Bulletproof Rock Solid, and Fast CPU

Summary: I bought 1 of these exact CPUs new for $200 back in 2004 I believe when I was building my very first computer system. I did a lot of legwork before purchasing the chip and out there for all of the socket 939 CPU's, This chip does the overall best in cost/performance in my book, for what it is, it has a lot of L2 cache, (2mb)(most of the other chips for a socket 939 had 128kb to 1mb) and in 2004, that was a LOT!!!
