Default multi cpu

can you use a multi cpu mobo for say a gamming rig for instance? or is it restriced to servers, just out of curiosity.

There's no reason you can't have multi processors.. you'll just have to buy a server board with two CPU slots. Most games won't take advantage of it though, it would just be a waste. You can buy an 8 core processor now anyway.. physical cores.

I guess if you had 4 monitors and a high spec game on each..lol

i know it would be a waste for gamming. but for say a compitition with cpu benchmarking lol it would own.

Yeah.. but you have to make sure all of the other hardware is up to par.

Not necessarily, Zackon.

With two separate CPUs, you introduce another variable. Namely, the bus or medium by which the two chips communicate. an Octocore chip is going to be better than two quads, because there's barely any latency between the cores. The combined latency between the two CPUs and between the CPUs and RAM would probably cripple it compared to modern multi-core chips. dual-chip setups are mostly used in servers; because unlike normal PCs - a Server has to deliver alot of resources to alot of people reasonably quickly, rather than a few resources to one person instantly. In this case, the latency between them is negligible especially over a network. The only consumer PC currently available that uses dual-chips is the Mac Pro, which is primarily for processing-power intensive activities like video editing, where the chips can both be fully optomised.

Long story short, the signals travelling between two seperate CPUs, and RAM and a GPU or two, would create such a noticeable drop in performance compared to a larger multicore chip in the same situation that it's rarely worth the effort. Besides, Most boards that support dual-CPUs aren't gaming boards, and tend to also only support technologies like ECC RAM and Mirroring (for protection rather than power).

Exactly. You would have to have two 8 cores for it to be awesome... then lots of RAM and some kick butt gpus... and a couple if ssd hdds
