Your x58 board and RAM should be in the +20k range.
Might want to check the settings or run memtest86+.
Good advice, however the RAM was free. This is a Dell (not my choice). At the time my sister ordered it, they screwed up and filled it with 12 gigs of ram. Unfortunately, it's their usual Elpida PC3-8500(F) @ 533mhz... As it's impossible to adjust timings with the Dell bios/mobo, I guess I'll have to settle for the score as is.
Attached is the screenshot of the timings. Could slow cheap ram be the reason my x58/950 is only showing ~15,000MB/s on the ram test?
