Looking to get CPU and MB, but what does this mean

Personally, I'd stay away from nVidia-chipset-based boards and stay with the AMD chipset boards if stability is important to you. The limitation in the AMD CPU memory controller is just that if you have more than 2 DIMMs installed, the max speed it can run them at is DDR2-800. With 1 or 2 DIMMs installed, max speed is DDR2-1066.
In general, you always want to have multiples of 2 DIMMs installed to take advantage of the doubling of memory throughput in dual channel mode.
I'd get 4 x 2GB DDR2-800 DIMMs rated at 1.8-1.9V (many DDR2 DIMMs sold these days are just slower RAM overclocked by the factory and needing more than the 1.9V max DDR2 standard voltage).

So when you day stay away from AMD chipset boards, do you mean not to use AMD CPU's?

What would be a good board to go with then?

Thanks

What he is saying is AMD chipsets are more stable than Nvidia chipsets see how the MB you chose is a Nvidia chipset.
Something like this if you already have a video card.

or these if need onboard video.

Im not sure of your budget.
Make sure you have a 64bit OS to recognize more than 4gb of ram.
you can get ddr2 800mhz from a reputable brand with voltage around 1.8v and be fine. I was looking at getting some of these

The AMD 790FX is an good chipset.

The Foxconn Destroyer Mainboard is an Nvidia 780A chipset and it is a very solid stable board. I have not had any issues with stablility, as a matter of fact my Destroyer is used as we speak everyday in a public gaming server 24/7 with a phenom 9950 be and 4gb 1066 memory.

The Foxconn Destroyer has a memory standard of DDR2 1066 Memory, supports Phenom 2 Deneb cpu with the latest bios update, is three way sli capable and can support 4 way graphics options.
The Bios is very stable with plenty of options. If you dont have or cant afford a new video card it has one onboard that will work independently or with another card and do hybrid sli. This mainboard also has all solid state capacitors for longer life inservice and more stability.

But of course, the Foxconn board is pretty expensive, too. Part of that is likely the SLI features, so if you know you're not going to use that (most people don't), you can save some money by getting a MB with a single graphics card slot.

i been wondering about the same thing... to be honest i totally despite AMD chipsets... the first time i used one was the 790fx (i believe so) and the RAID perfomance was sooo slow.. (i cant live without my raid 0... )
so thats why i use nvidia...

if some1 can confirm that this raid 0 issue was fixed.. i would go for amd chipset.. otherwise.. then a 790nvidia will have to do the job
