Not sure what is going on here. I just installed a new MB in my PC and have an I5-750 in it...The board is a Gigabyte with 4 GB Ram

Here is a link to the board on NewEgg

http://www.newegg.com/Product/Product.aspx?Item=N82E16813128404&cm_re=p55_micro_atx-_-13-128-404-_-Product

According to the passmark web site http://www.cpubenchmark.net/high_end_cpus.html , my CPU should be scoring around 4213 at the BASE clock speed of 2.66 GHZ..I have my system overclocked to 3.2 GHZ and am only getting a CPU score of 4033.

My memory is 4GB of DDR3
DRAM frequency is 810 MHZ
NB frequency is 2592 MHZ

I know the board is not a high end board, but I should be getting a little higher than that...Any idea what the problem could be?

Your DRAM is a DDR3-800 ?

Probably dual channel so DDR3 810x2 = DDR3 1620.

OP neither link works.

Yeah, i get you, that's not because of dual channel though, that's because its DDR (double data rate). The links work if you just copy and paste it.

Can you try just going back to stock clock and benchmarking it ? I think its because you might not have timed your RAM manually. I don't know what this benchmarking program does exactly but if you could just post your stock score then we'd be able to figure something out from there.

I feel like a dumby-I realized it was the 32 bit version of 7..Installed the 64 bit version of 7...and I am over 5k at a little over 3.0 GHZ..can't wait for my cooler to come in:)

I remember reading about 32 VS 64 bit versions of Vista and the 32 bit versions performed as good or better than the 64 bit versions--I guess things have changed with windows 7.
