Pros: Nice packaging,good looking heat spreader and the feel of quality,Easily installed these and immediatly when into bios as from reading the other reviews most ppl have had to manualy set these to 1066,Lo and behold it was set at 800,I set it to 1066 and it booted right up no problems.I replaced 2x1 gig 800 with these,having 4gigs of memory really makes a differance, Im happy

Cons: none so far

Overall Review: I cant hear the fan as others have said,everything loads much faster for me now. AMD x2 Calissto 550 MSA 785GTM-E45 Gigabyte GV-R4850OC-1Gh

Pros: Good looking board ,everything seems to be layed out real nice,booted right up for me using vista home prem 32bit,For now im using the onboard graphics and it actually works quite well,played WOW at 60FPS.I will be getting a card soon tho.

Cons: when I tried to install the drivers that came with the board win would freeze up when using auto run exe, So I found the graphics driver on the CD and after I installed it the auto run worked fine.

Overall Review: This board is working well for me im happy with it, I was able to unlock all 4 cores in the bios on my Callisto 550 but wasnt able to boot up so ill just have to be happy with dual core... live update was easy.
