Sometimes is BSODs at the Windows load screen, and now an occassional Overclock Has Failed message. But after I reboot at the same exact settings, it boots fine and can LinX, Prime, and loop 3Mark for hours.

I've tried raising and lowering Vcore without effect. I'm using XMP profile on my Gskill 2400 Ripjaw Z which seems to handle the times and voltages (including VCCSA).

Why it won't boot at settings that are otherwise very stable is tough to sort.

^ I have the same thing happen on bios 803. Doesn't seem to happen with previous bios versions so Im back to 079.

You can try what OC Nub suggests and / or check your pm for some suggestions on trying to pinpoint the issue.

Come to think of it, this may have started when I did flash to 0803. I don't remember the issue happening the first few days I was up and running. That's why the sudden boot issues kind of surprised me.

I will flash back to 079 and check my PMs as well. I very much appreciate your help.

Im not sure, tried one yesterday OPB had sent me, file reads "R4E83b". Wanted to try the Hynix profile because I am having issues booting at 2400 mem. But I think my IMC is just bad, so no luck

yes that is 0083, just a different name, same bios. Let me know if that is fine like 079

I had the same issue today with this 0083 bios, which is why I went back to 0079. Tried raising vcore but still no boot. To be fair, I did not do any stability testing with this bios, I just loaded the same voltage settings that had worked great with 076 and 079. It may have just need a few voltage adjustments, but I liked 079 so it was easier to just flash back.

Flashing to 079b didn't cure the issue. I made the suggested changes via your PM. If these work I will peel them back one at a time until I find the trigger setting. The no boot problem happens every 4 or 5 boots....it's not consistent. I can LinX, prime, 3dmark and play BF3 for hours at my current settings.

I can replicate reboots during idle with high VCCSA + low vcore, while they run fine at prime 95. please set 1.20v VCCSA as well when trying

Forgot to add this:

Keep VCore higher than VCCSA for stability
Try to NOT have VCCSA less than VCore by MORE than 300mv for stability

The 3930k is at stock. Everything is at stock.

And thank you for your help. I really appreciate it. :)

I think I have it sorted!

I lowered the VCCSA as suggested but the problem persisted...and seemed to worsen a little....BSODs 2 times in a row when booting when I usually would only get the one. So I went through the VTT and VCCSA settings at automatic and took note of all the preset voltages at the various ram speeds (1600, 1833, 2133, 2400). Although I was downclocking the ram from spec to 2133 and to 1833 (from 2400) the XMP setting was auto adjusting the VTT and VCCSA down pretty dramatically. I just went in and set the VTT and VCCSA voltages manually to be one step higher. In other words I set the VCCSA and VTT for the auto 2400 settings with the memory running at 2133. Boot problem gone.

It would seem so basic to have tried these voltage increases earlier, but the system was so stable under stress tests with less votlage I just didn't consider needing more voltage for a boot issue.

I didn't want to over volt more than I needed, so I brought the voltages down a little with some testing. I ended up with VCCSA and VTT of 1.3v for running the ram at 2133 and the CPU anywhere between 4.7 and 5ghz. Those voltages are somewhere between the 2133 (1.25v) and 2400 (1.35v) auto presets. I'd prefer to run those voltages lower as I know I am bench stable at 1.25v with anything I can throw at it. Even the 1.2v you suggested is LinX, Prime, and 3D stable. I'm not sure if there is something else I should be adjusting instead of these voltages in order to resolve the boot issue, but for now I'm rock solid it seems. I assume under good water cooling 1.44v Vcore and 1.3v VTT and VCCSA will be fine long term. In the meantime i will tinker with other settings over the next few days and see if i can resolve the boot issue another way and lower the VCCSA and VTT voltages.

I appreciate your help in this. I'm pretty happy with a 24/7 5Ghz SB-E machine. In fact, with the boot issue under control, there may be a little more under the hood still.

ya intel recommends to tie up vccsa and vcore in a good relation for stability

maybe a test such as underclocking the vgas and then running 2560x1600 or running 1080p WITH the gpus overclocked, to narrow down if power is an issue or not

Yeah, my Corsair AX1200 is the problem finally. I used another PSU and I don't get any repboot. :( RMA time for that 4 months old Corsair AX1200. :( Just ordered an Antec HCP-1200 to replace it, and will use the AX1200 in another system.

Thank you for the help.

Add me to whatever list of people with 4 card problems. My gtx 580 came back yesterday and I added it into my setup of gtx580, gtx 560ti (physics) and areca raid card. Machine went through part of post and turned off. It would not restart, i pulled everything down to a video card and 1 stick of ram and all i got for several hours was a series of hangs on 14,19,AF,61,65 so it seems like the cpu is gone. While you're thinking PSU I have two a PC power of 910 running hard drives and a coolermaster 1250 running the board,cpu and video cards--can't see any problem there that setup was running a sr2 with two 5680 and 24mgs of ram with 3 video cards--steve

1.3v for both VCCSA and VTT cured the issue. This works when the CPU is in the 4.7-5.0Ghz range, running the memory at 2133. Lowering the memory speed or the CPU overclock allows for VCCSA and VTT to be lower.

At first I thought my IMC was just crappy on this 3960X and I simply needed the higher VCCSA and VTT to get the memory clocked to 2133 when the chip was overclocked over 4.5Ghz. But knowing that I can run LinX, Prime, and 3D for hours at 1.25v VCCSA and VTT once I acheive a successful boot tells me there might be some other settings I'm missing.

Mimic my problems. With 4 cards, my first Rampage wouldn't post anymore just like you, with a solid red CPU Q-LED, no matter what I did. Had to RMA the mobo. Thaught the 3930k was dead...

Couldn't post anymore, just like you, like the CPU was gone...

But that CPU is working fine on the second Rampage...

UEFI 0901 for the R4E.

1. Improve high frequency DRAM compatibility.
2. Add more options to Latency Boundary item.
3. Enable UEFI driver support for add on cards.

Is there a memory QVL for the r4e?
