I installed these in my Dell XPS 720 tower. It maxes out at 8GB of RAM running Windows 7. The motherboard cannot take anymore, since it was developed for DDR2 capabilities mainly. I installed the new modules, the BIOS picked up the new DIMMS, continued the boot up process and once in Windows 7, I saw all 8Gigs of RAM with no issues. Very happy with the modules, also they look cool with the heatsink casing.

I installed these in my Intel D975XBX2 board to replace some Kingston HyperX which never worked @ the rated DDR2 800 Mhz. They worked right out of the box and have no complaint so far. They just rock and the price could not be better.

Purchased this memory for a brand new system build and so far it's been working great. Make sure you get a 64 bit operating system, otherwise your system won't recongnize the full 4 gb. I'm planning to upgrade, in the future, to 4 gb more to make vista run even smoother.

My system specs( all purchased from amazon ):
Intel core 2 duo e6750 @ 2.66
Abit Ip35-e motherboard
XFX 8800gt alpha dog edition 512mb

Used in Dell XPS 210 compact desktop as a max upgrade option. I made so many changes at once (incl SSD, videocard with integrated cooling fan) that I can't attribute the improved performance to the Corsair card alone but the whole systems runs SO MUCH faster, cooler and quieter that I don't know how I ever tolerated it before.

I only gave this a four because one of the two I ordered was bad and I had to send both of them back to Corsair for replacement. I am being told that two packs are paired together so even though one of them worked I had to send them both back for replacement.
I have read over and over again that when adding RAM buy the exact model of ram that is already in the system or replace all the chips with the same new models. I already have these exact two in my system and since I went from 32 bit XP to 64 Bit Windows 7 I decided to up my RAM only because I could.
Windows 7 is so much faster than XP it is truly amazing!
I did NOT by the RAM to make Windows 7 faster I bought the RAM because I could and because I am staring to do a lot more 3D CAD and Animation and that takes a lot of horsepower.
BUY THIS RAM IT IS WORTH THE PRICE!

I've used Corsair for almost a decade and only had one stick of memory go bad. They replaced it within a week. Simply the best company. Maybe it's not the best price, but it stays cool, works fine, and I trust corsair.

So they worked right out of the box at the speeds they should. I guess for most people that's great. But that's where the performance ended for me. I have overclocked my PC's for years and have always used corsair memory. Anytime I have tried any other high end brand of memory they either failed within a month or failed instantly. I also love corsair for over clocking they always leave a lot of overhead play room to push up timings and voltages. ANY kind of increase with timings or voltages with these and my PC beeped and wouldn't boot.

So from me they only get 3 stars (it's ok). Corsair normally gets 5 stars from me for all their products.
