[help]combining ddr3 with server ram

So here's the dealio.

cpu: i7 920
mobo: asus p6t deluxe v2 (it has six dimm slots)
ram: 6 gigs of OCZ ddr3, 2 gigs per stick. and here are the specs on my ram.

"PC3 12800 8-8-8 @ 1.65v OCZ3G1600LV6GK"

In bios I had my DRAM Frequency set to Auto.

SO, turns out my boss lets me take home some leftover server ram.

specs on server ram: "2GB 2Rx8 PC3 - 10600E - 09 - 10 - E0"

i pop them in, and hope for the best. computer recognizes 12gb of ram. windows boots up fine, about 5 minutes go by and BAM. blue screen. happens so fast I can't read what it said. so immediately my first instinct is to go into BIOS and change some kind of dram setting. I change the DRAM Frequency to DDR3-1066MHZ, reboot and everything is dandy. no errors.

But heres the thing- there's no noticeable change in performance. nothing negative nor positive.. so being curious i load up speccy and under RAM i see this: "12.0GB Triple-Channel DDR3 @ 535MHz 7-7-7-20"

535mhz? geez. more detailed:

Type DDR3
Size 12288 MBytes
Channels # Triple
DRAM Frequency 523.5 MHz
CAS# Latency (CL) 7 clocks
RAS# to CAS# Delay (tRCD) 7 clocks
RAS# Precharge (tRP) 7 clocks
Cycle Time (tRAS) 20 clocks
Command Rate (CR) 2T


anyways... I have more info if needed, but basically..

what do I need to do here to get this ram to work together well? or is it just not going to happen? please help! thanks!
