Pros: Seemed to be reasonable price for upgrading an older computer and most other Newegg reviews were favorable. Newegg provided prompt delivery.

Cons: It immediately crashed my Dell Dimension 4550 (533hz) PC and corrupted the BIOS. Reinstalling OEM memory did not fix it and Dell tech support did diagnostics and referred me to Corsair for help on this 3rd party upgrade. Although I selected this memory using the Newegg memory configurator, Corsair said it was NOT compatible and could not/would not assist in fixing my computer. After pleading with Dell, they helped me reinstall Windows for the OEM memory configuration but at the expense of losing critical files. I am still struggling to reload applications and drivers. Dell recommended against trying to reprogram the BIOS to avoid inducing failure of the over 5 year old motherboard.

Overall Review: I am not a computer whiz, just a retiree trying to keep an older computer going on my fixed income. I do not know why this PC3200 memory does not work in my computer or why Corsair only recommends 266 Mhz PC 2100. The Dell configurator recommends 512Mb 400 Hz PC 3200 memory for this computer. Since I relied on the Newegg configurator, I asked Newegg to waive the restocking fee and to give a full refund including s/h plus what I paid to ship it back. I hope they will at least do that for all the grief this has been from an incorrect configurator.
