Dead CPU Rampage V Extreme Unidentified LED

Anyone help on this?

I have just had a CPU die on me. It was a rather fine 5960X. It was a good OCer...tested but not benched since it's too hot here at the moment...

So...it was running at stock when it died. Switched off fine one evening...dreaded code 00 the next morning.

When I switched on that morning a very bright red LED lit up next to the 4pin ATX connector on the RVE...it is not listed in the manual....the PCIe lanes also lit up but not the correct ones for the occupied lanes. And indeed one of them was flasing?

Any clue from ROG Illuminati (pun intended) to help me understand what happened?

The LED next to 4pin ATX only lit up on first fatal boot attempt...has not come on since....strange PCIe light behavior has been same.

Not the board...have a new CPU in it now and all working great....

:confused:

EDIT: 29/Oct

Have replaced motherboard with 3.1 version of same; night and day difference in behaviour; there is definitely something wrong with VRM of affected board and I think it probable given the silence in this and other similar threads that the board killed the CPU by overvolting on startup

EDIT:31 August 2016

In the interests of truth/knowledge...lack of either...

Board worked OK with other CPU, though had slightly strange startup still...now not sure if board VRM was killer or FIVR on CPU was killer or combination or none of the above...

Have seen multitude of similar complaints...but all different hardware, OCing, behaviours etc etc. very difficult to pin down.

ASUS, no comment, which is not on....

Arne, I followed the tutorial that you gave to OC my 2666 ram with all the settings in the post which was working great even tho it's not 3000. It's an awesome post and worked great!

Just updated to 1701 prior to doing this..

It's been fine for about a week, I rebooted today and noticed all the fans shot to full load so I opened the AI-suite and looked in to see the CPU and cache adaptive set to 999+ which was quite a scare!

I saw the cache voltage showing like 2.9V so I drug the slider to 0 and clicked apply fast.

Since I'm new to the x99 board I'm going to do some testing and see if my board burns up CPU's like the Extreme that ate 3 4770k's.

I wonder if this same thing was happening with the voltages because before I never bothered with ai-suite.

I'm just glad the people at Micro Center have such great replacement plans.

Ouch...sorry to hear that!....AI suite is not a favourite of mine I have to say....can trow up a lot of false info if it conflicts with other programs....but if the fans were spinning up sounds like something went awry for real?

Shame we have to rely on exchange plans!

Keep a close eye on it!

I have just swapped out my motherboard....could not rely on the other one

Ouch....from OCing or on start up?

Too many dead CPUs in this thread :eek::(

Sorry to add fuel to the fire folks, but I've now killed two 5820Ks with this board. One of the guys at my local Microcenter said it may be a problem unique to the 5820K and how Intel cut the PCI-E lanes, but seeing this thread I'm not so sure.

In both cases I had a mild overclock with more than adequate water cooling. The first one died slowly over the course of several weeks, second one worked fine until I rebooted, then it was totally dead. I even RMA'd the board the first time and ASUS sent me back the same board without any apparent changes.

I think these boards are sending too much voltage to the CPU socket on initial POST. Has anyone who owns the 'revised' version that came with the USB 3.1 card had this issue?

There is no revised version, they threw a 3.1 card in the box, end of.

well if no one is listening then wtf are we doing here ---surely the issue is there , atleast on evga forum they do listen some times , like i remember the time when they wont give a new update on sr2 bios after a lot of ppl created havoc over there evga released a bios update for sr2 even .
but killing usd 1000 cpus and geting away with it is bad scene.

i have a new revision rampage v which came with the usb 3.1 device and i also got the over voltage message

That's what I thought, wasn't sure if maybe they also fixed this issue and didn't tell anyone, knowing that if they said anything they would have to replace all of these boards.

Sounds like that's not the case.

Dam* . . . this thread is bumming me out. . .. So is there no way to keep the MOBO from sending "too much voltage to the CPU socket on initial POST?"

Perhaps the bios page explains it all?

RAMPAGE V EXTREME BIOS 1701
Improve system stability.

Would that mean it's possible that it won't kill my CPU since I updated bios to 1701?

It'd be nice if there were more details on the bios releases.

No, system stability probably translates to - We can't tell you as we really messed up the last release (again)

Asus have used the stability line in a lot of releases and never disclose the real reason behind it.
