CPU not getting power?

[drdisappear]

I recently recieved:
xfx680i LT SLI board
Q6600 CPU
(2)8800 gt's
2 gb ocz sli ram
550w ultra PSU
Vindicator headsink
500gb WD hard drive.

I assembled everything as per the xfx intruction guide for the MOBO, as well as everything else by the book, i went to power on my computer and got a green, yellow, and blue light on my MOBO, all the fans come on in this case, but no signal to my monitor. I havnt been able to locate where to plug in the case speaker wire on this MOBO to see whether or not i can hear the beeps, but i have tried MANY different solutions to try and fix this reading many different post. One thing that does seem to differ in my situation is that i tried to take off my heatsink momentarily and turn on power just to see if i could feel the cpu getting warm, and it doesnt change temperature at all, which would seem to me to be that its not getting power. Iv triple checked my 8 pin connector and tried reseting CMOS with the jumper, i havnt removed the battery yet as i just read up on that and will try it next but any other suggestions would be appreciated.

That Mobo doesn't have a SYSSpeaker header nor a onboard speaker so you will get no beeps.

The CPU doesn't get hot at all? It should go like this in 3 seconds with out a heatsink...

Yeh it doesnt raise a single degree, i was very aware of the dangers b4 i tried it, had my finger on the psu off button incase it heated quickly. Anywayz im thinking RMA is the only answer after reading about 30 people with the same issue at Tigerdirect's site.....

Boot up with one stick of RAM, set volts to 2.1-2.2 then put in 2nd one, sounds like you have a regular OCZ problem. The won't run at stock volts, you might even need to get a bad stick of RAM to boot it up, then set volts high, then put in OCZ.

That 550W Ultra PSU you are using isn't gonna cut it with your setup. I recommend getting a better PSU.

EDIT: What Miker means is you could get a cheap DDR2 stick that you can use so you can atleast access the BIOS to adjust your memory settings according to the SPECS of your OCZ memory. A DDR2-667 stick will do.

[drdisappear]

So not having ram in will cause the cpu to not recieve power? If so i wasnt aware of that and ill try an old stick real fast.

[Miker]

Yaa, that PSU is also very underpowered.

[drdisappear]

In response the the PSU comment, i realize it is on the low side but im willing to run a single GPU until i can get a better PSU, in which case my current one can handle that load, but regaurdless that shouldnt be an issue running bare minimum's for boot up and having no signal.

[werty316]

You need a atleast one stick of memory installed for a computer to boot up.

Try booting up your computer with only the bare minimum parts required to boot a computer up like the motherboard, a CPU, CPU cooler, one stick of memory, one video card, and a PSU; have nothing else installed.

If I was you I wouldn't have tried to turn your computer on without a CPU cooler installed at the risk of damaging your CPU as it would take less time to kill your CPU than the time it would take for you to react and turn the switch off on your power supply.

[Miker]

You need a atleast one stick of memory installed for a comptuer to boot up.

You need one stick of working RAM, OCZ needs so much volts it might not even run.

[werty316]

Not every OCZ memory kit needs alot of voltage, after all we don't know if he is using DDR2-800, DDR2-1000 or DDR2-1066 SLI memory so don't make any assumptions that his problem is that he needs more memory voltage because he is using "OCZ" memory.

Also what kind of comment is that when you say that all OCZ memory sticks need alot of memory? Its a crap one since the amount of voltage a stick of memory requires is based on its SPECs so a non-"OCZ" kit can also require alot of memory voltage.

EDIT: 2.1V is the rated SPEC voltage required for his OCZ DDR2-800 SLI kit which is quite normal since most kits rated at DDR2-800 require 2.1V which isn't really alot of memory voltage.

Tried 5 different sticks of ram, tried all 4 slots, nothing.
TO narrow this down let me tell you what i have done so far, tried 3 different video cards, 2 different monitors, 3 different types of ram ranging from good to terrible, tried with everything hooked up in which all the case fans and fans on both gpus worked but no video, tried with bare minimum in wish fans worked but no video, tried reseting cmos/battery. Im all out of ideas unless using it as a frisby is more satisfying than playing Crysis.

[drdisappear]

btw the OCZ memmory is DDR2-800, the other ram iv tried is ddr2-533

[werty316]

My only advice I can offer is to try another CPU and PSU and if that doesn't work you might have a DOA board.

[Miker]

I guessed RAM because it was SLI ready.

I would replace PSU before you RMA Mobo as you will need a new PSU anyways, and it is just more testing, and more testing is the best testing.

[werty316]

Since you never mentioned that you tried another CPU and PSU I would start with that and go from there.

:offtopic:

SLI ready memory is a marketing feature that certain motherboards have so that a user can overclock a SLI ready memory kit automatically without the need to worry about adjusting any memory timings or memory voltages.

In a nutshell its a form of plug and play automatic overclocking for your memory.

[drdisappear]

alright well im not sure if im going to be able to obtain another cpu but ill try a diff PSU, thanks for the replies/tips.

I know what SLI memory is, but I just assumed that when he said SLI memory he meant a good set of OCZ that needed the extra volts.

you could get a speaker to plug into the mobo to see if it gives you any beep error codes.

680i LT has no speaker header.

680i LT has no speaker header.

hmm....make one? :lol:

Is your motherboard mounted in the case? If so, there may be a chance that your motherboard is grounding out. There is a possibility that you will still have the lights come on the board, but I am not familiar with this board.
