Could anyone offer some advice on my previously posted mobo question? I've already purchased the CPU and RAM finally, and the mobo, HDD and OS are the only necessary things left to get (Well, OS is optional, but everyone says Vista 64-bit is great for a 4GB system).
The CPU is an Intel Pentium Dual Core E5200 (800MHz FSB) and the RAM is PC6400 DDR2 800MHz. My question is what restrictions does this put on what motherboard I can buy, apart from obviously needing socket 775 and DDR2 compatibility. Does the FSB of the motherboard matter greatly, or can I just get anything above 800?
Also I was thinking of getting a front 3.5" bay USB/multicard reader, and I wasn't sure exactly how they connect to the motherboard. The pictures I see on Newegg all have some sort of black ten pin connector, but do all motherboards have a place that that would connect to?
Your E5200's actual FSB would be 200mhz. It's usually the face value (in your case, 800mhz) divided by 4 - so it should be 200mhz. (don't know why you divide by 4, but that's just the way it is.)
And your PC6400 DDR2's bus speed would be not 800, but 400. Dual Channel, which makes 400 + 400 = 800mhz.
Which means, your CPU is running at 200mhz, and your Ram's running at 400mhz. This would click as 1:2 ratio, and works great.
Your optimal (say you are not touching any settings on RAM) CPU would be something that runs at 1600mhz. It will create 1:1 ratio (400mhz for CPU, and 400mhz for RAM) - but 1:2 is good too. Also, even if you OC your CPU to 333mhz or whatnot - your motherboard will create something called "Divider". So even if your CPU FSB and Ram FSB doesn't really match as 1:2 or 1:1 - it will run fine. (such as 5:8, etc.)
FSB supported on the MB does matter, so I'd make sure that your MB support your 800mhz fsb by checking the specifications - but I have a feeling that most MBs would support 800mhz. Most MBs have harder time to run higher FSBs than lower FSB (and 800mhz isn't that high, these days).
Myself is relatively new to this whole computer building scene, so I can't say for the 100% - but I just don't see why any MBs these days wouldn't support 800mhz. But some do have problem running newer 45nm core CPUs, and sometimes you need to update your bios to begin with. If your MB doesn't support 45nm CPUs from the get go, you'd need a older CPU that would recognize to boot, then update bios, then change the CPU... and that's a chore..
As per 3.5inch media six pin connector or whatnot - perhaps it would go to one of the internal USB port on MB? Just a guess...
