[SOLVED] R4E + 4930k Debug 00 CPU_LED Red

ResHacker

Update Dec 26 2013: ASUS sent me a new motherboard. It posted successfully after flashback to 4701. Big thanks for ASUS RMA dept!

Update Dec 18 2013: Motherboard is sent back to ASUS. Now the status is "Product repair is in progress."

Update Nov 21 2013: Unfortunately a new CPU did not resolve the issue. Any more suggestions? Or I should contact ASUS for RMA the motherboard now?


Hi all,

I am trying to install a 4930k to Rampage IV Extreme 4 (Initial BIOS 4102). At first boot it gives Debug 00 CPU_LED Red which is normal, since the BIOS version is too old to support IV-E.

Then I updated 4102 to 4403 using Flashback. The update was successful, since I used a FAT32 USB stick with the filename R4E.CAP, and after pressing the ROG button for about 5 seconds, the first BIOS LED starts to blink, and then faster, and then stable. The whole process is about 2-3 minutes. The strange thing is that, after the BIOS update, the Debug 00 code and CPU_LED Red still persist.

Then I enumerated all the BIOS versions 4206, 4403, 4502, 4503 in order, on the first BIOS and the second BIOS. They all give the same result of Debug 00 CPU_LED Red. I also put the CPU out and back 3 times, nothing changed.

I think at this point I will have to RMA one of the components. The question is, which one is more likely to result in the problem, CPU or the motherboard?

FYI, hre is a list of gigs I had for the build:
Case: Corsair 900D
PSU: Corsair 1200i
MB: Asus Rampage Extreme IV
CPU: Intel i7 4930k
MEM: 8 x 8GB Corsair Vegeance Pro 1866
HDD: 1TB Samsung 840 EVO SSD + 3TB TOSHIBA 7200RPM HDD
GPU: 2 x EVGA GTX Titan
CPU Cooler: Koolance CPU-380 Liquid Cooler
GPU Cooler: 2 x Koolance VID-NXTTN Water Block

Thanks for any help!

Unfortunately the new CPU did not resolve the issue. I should probably contact ASUS for an RMA on the motherboard then?

😞

Ufff sorry ResHacker....gave you the wrong advice it seems 😞 though it was based on what had worked for most people I'd seen so far...

Yep must be the board...hope you have a quick turnaround on that at least.

EDIT: actually I'd feel uncomfortable saying anything like "must be" in this thread. I wonder if you have another computer around that you can test your PSU on because if the 8pin ATX power is not working it might give this result too...

RMA the motherboard is the next step as you seem to have used two different PSU's if I recall correctly.

The motherboard is sent to ASUS and now "Product repair is in progress." 🙂

Tic Tok Tic Tok....eh? you hitting F5 often? 😉 fingers crossed it's short and sweet turnaround.

Hi All,

I have exact same hardware as ResHacker except for a little more RAM and one less Titan.
I too am having exactly the same issues after having received the components and built the rig this afternoon.
Disappointment is an understatement, after paying so much money for supposed good quality products.

If I stuffed something up during the build then no problem for me to take the blame; but it does seem too much of a coincidence that we have the identical issue.

My strategy will be to take my box, as I've assembled it, to one of the resellers and get them to identify the culprit i.e. me or the high end ($$$) products we decide to align ourselves with.

Chances are they'll be too busy to do it there and then; and with Xmas and all who knows how long it will take, but I'll certainly reply with my findings here.

Leon please start your own thread mate, you may think you have the same issues but experience has taught me that very seldom do two users have the same problems. Each solution is pretty unique.

Today I received a new motherboard (not my original one but maybe a previously fixed one). It posted successfully after flashback to 4701. Big thanks to ASUS RMA Dept for giving me this great news during Christmas!
