Need help with Patriot Viper II Sector 7 Edition 24GB DDR3 1600 (PV7324G1600ELHK)
MB: ASUS P6T (1408) (X58/ICH10R)
CPU: Core i7 920 (C0)
SSD: OCZ Agility 3 120GB (2.15)
GPU: GeForce GTX 470
OS: Microsoft Windows 7 Ultimate (64-bit)
I just purchased the "Patriot Viper II Sector 7 Edition 24GB DDR3 1600 (PV7324G1600ELHK)" memory kit for my system, but it will not boot if I attempt to use the XMP Profile for 1600.

It sounds like it could be a bad stick or possibly slot...
To test the memory, can you please try testing with Memtest 1 stick at a time on each slot to see if you can find a defective stick and test the slots? Please run about 2-3 loops.
Memtest can be found here: http://www.memtest.org/
Thank you for the response, the BIOS is up to date, and I will begin to test each stick individually.

I ran Memtest and it found no errors on single or all of the kit, it seems to run stable at 1066 and it does boot @ 1333.
MB Settings with X.M.P. Profile set:
QPI/DRAM Core Voltage: 1.25000
DRAM Bus Voltage: 1.66
CAS Latency: 9
RAS to CAS Delay: 9
RAS PRE Time: 9
RAS ACT Time: 24
DRAM Timing Mode: 2N
Everything else is AUTO.
If I manually set the timing of the memory, but leave the voltage to Auto it will boot, but will BSOD in Windows, with the "DRAM Bus Voltage" set to 1.64 it so far hasn't BSOD, but if try to manually set the "QPI/DRAM Core Voltage" to 1.25 the system will not boot.
I tried setting the QPI to 1.30 and the system would boot with the 1600 settings, but stops before it loads Windows.
Ben, do you think it will be safe to run the QPI at Auto and the RAM at 1.66v?
Yes, you can run the QPI at auto. QPI can usually be .50 v lower than dram voltage. If you're using 1.66 Dram Voltage, you should be able to use 1.15-1.16 QPI Voltage.
It sounds like you might have one bad stick or slot somewhere. When you insert all of the memory in, does it register all 24 GB's?
All 24GB are seen in BIOS and in Windows, and the system seems to be stable, I checked all of the first channel slots, none will boot with the XMP profile with 1 stick, I also tried a dual channel kit I had recieved for another system that was also 1600 9-9-9-24 1.65V, it set the QPI to 1.20 and also would not boot once saved, all of the memory has passed in Memtest together, running each stick individually will take about 6 to 12 hours to do 2 passes.

Wasn't stable with DRAM set to 1.66 and QPI set to Auto, so I have turned the DRAM down to 1.64, also my board doesn't support a QPI/DRAM Voltage less than 1.20.
Wasn't stable with 1.64v.
I may test each memory module tomorrow or just see if I can get a refund.
