Over or underclocking my HyperX RAM?

[aln688]

I'm planning on overclocking my Intel Q9550 Quad CPU from the stock 333 x 8.5 (2.83GHz), to an FSB of 376 x 8.5 (3.2GHz). I have an Intel DX48BT2 motherboard and Kingston HyperX DDR3 1375 modules (2 x 2GB).

As I understand it, these HyperX RAM modules are rated at 1375 effective, which is actually only 687.5. If I run the FSB to 376, this obviously results in a system FSB of 1504. Am I correct in saying the RAM is underclocked by running at 376 * 2 = 752?

Two questions:

(1) Am I overclocking my RAM by running it at 752 over 687.5, or am I underclocking my RAM by running it at 752 under the rated 1375?

(2) If I run my RAM unlinked would this hurt performance much? As I understand it, linked means the FSB is in exact tune to the speed of the RAM?

well having the ram faster than the fsb offers pretty much no more performance, so you may as well run it 1:1 and tighten up the timings resulting in better performance!
