New build booting up for a few seconds only

I am putting my new build together but its experiencing a problem booting up. For some reason when I turn it on, it only boots for a few seconds 3-4 and then turns off. It repeates this sevral times, mayabe 1 out of 10 boots does it actually boot. Any Ideads? Heres my new build config:

MB:ASRock X58 Extreme LGA 1366 Intel X58

MEM: OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory Model OCZ3G1600LV6GK

CPU: Intel Core i7-920 Bloomfield 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920

PSU: OCZ ModXStream Pro OCZ700MXSP 700W ATX12V V2.2 / EPS12V

HD: Western Digital VelociRaptor WD1500HLFS

I manually set the DRAM to DDR23 1600. Do you thing i need to change the timing? Also It appears to work more often when only 1 memory module is installed?

BTW, I just set the DRAM timing to 1.65, but i still have the problem. When i removed the 3rd mem module from the MB it boots up more often.

It could well be a power supply problem, try substituting the power supply.

I dont' have another PS on hand, but i will try to go to the local pc store and see if they can test it with another PS. For some reason in dual channel mode it seems to boot fine. I even tried different mem module combinations, and all work in dual channel mode , but as soon as I install the 3rd module it boots for 3 seconds and then turns off. BTW I set the memory timings to 8-8-8-24.

What video card?

Sorry, nvidia quadro fx1800. FYI: The 1st motherboard had the same problem, so I thought it might be the MB and RMAed back to newegg. I guess it could be a compatibility issue with the memory or the PSU???

BTW, by boot up I mean from being turned on (not from vista being started), aka I don't even get to the BIOS menu.

I removed the graphics card and same problem, the MB wants to boot up but just turns off after only 3 seconds. I can't get to the BIOS to modify any settings as it turns off well before the boot menu.

Try booting with only the video card, hard drive, and 1 stick of RAM.

I removed 2 sticks of RAM and the BIOS boots up more consistenly. BTW, I don't have any problems with BSOD or Vista 64 locking up. If the system can stay on long enough for the BIOS to run/boot to RAM???, then the whole system runs. Any Ideas?

Have you run Memtest86+ to test for RAM problems? It sounds like a possible dead stick of RAM. Are you sure you're using the correct RAM slots? Most X58 boards require you to use the RAM slots starting with the one further from the CPU socket. That would be the white slots on your board. The motherboard manual will tell you for sure. If you are using the correct RAM slots, I would run Memtest86+ on each stick of RAM by itself.

I put the RAM in the white slots (per the manual). Slot 1 is closest to the CPU. The ASROCK X58 included a sticker that showed how to order the sticks, starting with the one CLOSEST to the CPU. Also I ran Memtest on each stick and they all individually passed.

I placed the 3rd stick in slot 1 and the the bios bootup after the 3rd try. The system booted into vista with the 2nd stick and 3rd stick.

Try the 2nd or 3rd stick of RAM in the 1st slot as you did the 3rd stick. See if you get the same result.

Well I did some more research ocz forum and modified the vtt volage to 1.34 and then ran Prime95 on each stick in slot 1. Each passed. So know I have added all 3 back in and I am going to run prime95 again. On the OCZ the forum threads recommend QPI also set to 1.34V, but the only options are 4.800GT, 6.xxxGT on my ASROCK x58 extreme???

Heres what I have so far know:

I have set DRAM = 1.654V
I have set VTT =1.34V
I have set my RAM timings to 8-8-8-24 , with tRAS at 88, and 2T

I have made no changes to CPU, letting it run at its native 2667MHz speed.

How long should I run Prime95 on all 3 sticks?

I would start it and let it run overnight.

You may also want to download cpuz and verify your settings.

well, I had to reboot the box, and now back to the same problem again. turns on for 3 seconds and shuts off with all three sticks in, so i can't run the vista/prime95. Does not make sense since each stick runs prime95 for half an hour and with no errors. Gonna try to get OCZ tech support on the phone, this is way to flacky.
