My build won't start to BIOS (no video).
I've tried with two types of memory and monitor is plugged to the VGA output of Mobo... 

Here's a link to Dr. Debug https://youtu.be/onykSkCwdPg

I've got nothing connected besides 2 x CPU (Xeon-e5 2670 v1).

Could it be the Mobo or the PSU or have I just forgotten something important?! CryTongue


Thanks in advance!

Looks like all memory POST failure codes on the Dr Debug display.

Full model name and numbers of your memory, please.

Also, which DIMM slots are you using?

Thanks for looking into it.

First memory I tried:

RipjawsZ G.Skill DDR3-1866 CL10-11-10-30 1.50V PC3-14900
F3-14900CL10Q-32GBZL

and the second

Kingston 16GB PC3-12800 CL11
KVR16R11D4/16HB

I've tried different DIMM slots but mainly A1, B1, C1 etc

Try this while waiting on parsecs reply.

And yes. I agree with parsec. This is memory related.

I'm assuming you have 4 sticks from the kit F3-14900CL10Q-32GBZL.

One stick in each, A1, C1 and G1, E1


You might probably should clear the BIOS before trying to boot again with them in the slots above.

Reply with the results please.

Hi!
Yes, indeed the kit is 4x8GB.
I installed the memory as advised and took out the CMOS battery for a while.

The result was about the same as before:

Tried it with the server memory (KVR16R11D4/16HB) as well... but nothing... hmmmm....

First build that I've had problems with, makes me mad LOL

Nope. In the video, which describes as ""Slots A1, C1, E1, G1"" they are actually pictured in A1, D1, F1, G1.



The two sticks that reside in the two banks below the CPUs as pictured in the last video, move each to the bottom slots below their respective CPU.

More simply, try the sticks in the four slots furthest from the CPU. As I originally suggested, slots A1, C1, E1, G1

I guess I'll have to learn the alphabets again :)

I changed the DIMMs.... Still nothing Unhappy

I really don't have personal experience with what's in front of you. What I did suggest is what I understand(or may not) in terms of your issue. Sorry.

Please contact ASRockRack Tech Support http://event.asrockrack.com/tsd.asp" rel="nofollow - HERE and inquire of them.

And so I may glean the correct information if you'd post back the outcome I'd kindly appreciate you doing so.

I set up this same board last week with dual E5-2670's and it was a little tense on the first power up. Takes a while to get to the POST on this board after power on.

I bought 64 GB of RDIMM memory in 8 sticks, filling in all the blue slots. I believe the manual says to put at least one stick into a blue slot but doesn't give a lot of details, just some mention about "dual channel technology" when this board really supports quad channel. Cut & paste, I expect.

The memory I used was Samsung 8GB 2Rx4 PC3-12800R REG Server RAM M393B1K70DH0-CK0

I read mixed results with non ECC and non RDIMM (which is not to say configurations are not supported).

I waited for 5 minutes and nothing Ouch

Waiting for ASROCK to answer my mail... Guess I'll go and get all my parts checked somewhere tomorrow...

Your Kingston memory is compatible with your CPUs and board, and you have four DIMMs, so you can use two for each CPU. The G.SKILL memory is not in the QVL list. Use the Kingston.

You have both CPUs in the board, correct?

Your video shows cables to both CPU power connectors, I can't tell if the cable is correct or not. Be sure not to use the PCIe power cables for the CPU power.

Both videos shows the G.SKILL memory, try using the Kingston again. Clear the BIOS before starting the board again after inserting the Kingston memory.

You can try using only one DIMM for each CPU at first, inserted in one of the blue slots farthest from the CPU socket. Or two DIMMs, again in the blue sockets farthest from the CPU.

The POST codes shown, which sequence through each CPU and memory set, were memory errors, but that was with the G.SKILL memory.

Yes, both CPUs connected. Yes, the power for the CPUs is thru CPU cable.

I have two 2x16GB Kingston memory.

I tried multiple times with the Kingston (one memory in slot A1 other in every blue slot) as well... no video, same Debug codes....

I took my PC to service so that they can check all the parts...

I'll let you guys know ASAP...

Hi!
This sounds pretty weird but here's what happened.
I took my PC to service, the guy tried to get it work (no video thru onboard VGA)... When he was about give up he installed a graphics card (not mine) to a PCI-E slot he got POST.

I got home and installed my graphics cards (2xgtx980ti). The machine started to cry again.
Seems like the other GPU is broken. I don't know if it can affect the Mobo but when I only install that GPU and boot I hear bunch of beeps from the motherboard.

Booting after that using only onboard VGA nothing happens just error codes.

With the other GPU everything worked fine.

I hope you understood something that I wrote :D This case ws so weird. And we did not even touch the Memory (Kingston).

Thanks again guys for your help!

So one of the GPUs is dead?

So the system works with the other GPU installed?

Yes. Everything seems to be working perfectly now.

Note to self: Always troubleshoot with the bare minimum installed. Smile

NM the two SLI'd GTX 980ti's LOLWink

Us Mods must get better at asking for system specs at time of troubleshooting/diagnosing.

Now I have my build running 2xgtx980ti and 64GB RAM and it's smooooooth ;)

Thanks again to all of you!!!

You guys rock!!!

Hi, just to add my experience to this:

I built a system with the same MB, two HyperX FURY 8 GB DDR3 1866 MHz, and a Gigabyte NVIDIA GTX 750Ti 2GB PCI-E GPU (just to get an HDMI port).

When I powered the system up, I got nothing at all except a green LED on the MB just below the power connector, and another flashing by the PCI slots -- no fans, nothing on either video out.

Removing the GPU made the MB power up normally, and I was able to run it via the VGA output.  I tried this several times while messing with the PCI settings in BIOS (e.g. changing the PCI version to 3, and back to 2), and it was totally consistent -- GPU in, dead as a doornail; GPU out, worked fine.

I rushed out to PC World and got an Asus GT710 GPU, and it works fine.  So I guess this MB isn't compatible with some GPUs.  Ouch.

My next problem was random crash / reboots, which was apparently due to Windows 10 -- it seems it's not compatible.  I'm now running Linux which is fine.  I've heard Windows 7 works fine too.

All the best!

I just want to say thank you for this post. I have been struggling to try and figure out why my computer wouldn't boot. I could get it to boot with one CPU but not two. And when it did boot on one CPU it took a long time. After reading this post I took out my Gigabyte GT740 card and it booted up perfectly and very quickly. Looks like I'll be swapping the Gigabyte card out for the Asus GT710 too.

Hello. I'm posting here my problem because I was not able to find a solution for starting a new topic.
So here is my problem!
I bought a new motherboard from a friend of mine. It is a AsRock Rack ep2c602. He bought it a few years ago but never used it. I tried to test it with a cpu e5-4620 v1 and a 8gb dimm of ram on it. The mobo start for a few seconds than stops and after that it start again for a few seconds and so on. I talked with AsRock support service and they were very nice people. They send me a Rom chip and a bios chip. I changed both chips and there is no change. Hope I'll find a solution here. I also have a little video with the mobo behaviour. I could't find a solution to upload it here. So i used wetransfer. This is the video link: https://we.tl/t-JkCxnubpdi" rel="nofollow - https://we.tl/t-JkCxnubpdi
Thanks in advance.

I found how to make a new topic. It is called "AsRock Rack EP2C602 no post".
