Question Major problem wont post.

[Afterburn25]

I am so frustrated. Been working on this for 2 days now. I've run out of ideas. Computer will not post. It just sits there with memory LED solid red. But if I shut power supply off for a couple minutes and turn back on it will post. But will make me hit F1 to go into bios setup. I do that save settings and exit problem starts again and wont post. I can boot up hard drive if while in bios I do a boot override and boot directly to disk will boot windows just fine at least till I need to do a restart. I've tested the memory it comes back fine. I also did memory test on motherboard when it wasnt posting and it would post for the memory test. I've pulled everything out and started from scratch still cant isolate what's causing this.

I'm running a sabertooth x79 3.6 intell CPU 64 gigs 1600 ddr3 2 1070 nvidia graphics cards 1 TB ssd 4 other sata hard drives 2 DVD drives with 1000 watt power supply.

Any one know what would cause this

When it does post are there any error messages that would prevent it from booting to your os?

No only message I get is please enter setup to recover bios setting. Press F1 to run setup. Everything looks perfect detects all my stuff just fine. I even flashed the bios from 4501 to 4801 and still not working right. Only thing I've noticed is red LED light for memory stays lit. Since I've ruled out bad memory I have to assume it's not even getting to the memory yet

Hi Afterburn25. I feel your pain and your issue is a RAM mismatch or failure and Post will not continue till rectified. At least your able to access Bios which helps.

What method did you use to test your memory.?
Have you tried the MemOK button after clearing CMOS.?
Did you try to boot with just one RAM module installed and switched modules into different slots to test.

Please report back.

Yes I used the ram test button on motherboard. I have 8 8 gig modules and yes I tried with one and I also tried different ones in different slots. Didnt help the problem and all seemed to test fine. One thing I did notice is there 1600 mhz but bios has read them at 1333 the motherboard supports up to 1866. They are all exactly the same corsair Vengence 1600 bought them as 2 32 gig kits

Also another thing to note is shutting power off from switch does nothing in order to get a post I have to shut off switch directly on the power supply and have to let it completely drain all power out of the motherboard. Usually takes 1 to 2 minutes. And in order to buut successfully into my OS when I go in bios I cant make any changes before I do a boot override if I do make a change it will reboot first and then it wont post on that reboot.

Also another thing that tells me it's not a ram issue is I have other ram chips I also tried with no luck also once in bios all my memory is ok according to the bios

 

[Afterburn25]

Ok seems I fixed it. Seems the problem was the configuration of memory. These chips can run on default and have to run in xmp mode with the bios defaults for the voltage and timings.
