The VCORE is in YELLOW, it is 1.280volts.

Okay, if you wish for the CPU to down-volt when idling, choose Offset Mode where it says "CPU Vcore Voltage". If you want the same voltage 24/7, then you select "Manual Mode", like it is in the picture. Even though the voltage value is yellow, it is still a relatively safe value. Remember, no Overclocking is 100% safe, but many voltages can be raised to a reasonable level and not harm your system. If you choose" offset mode", a field just like the one with the yellow value will appear, and and "Offset Mode Sign". To overclock choose "+", and add a voltage like the one I mentioned above. you can start at .0300 for instance, and raise it from there until you get stable.

As it was mentioned, you do not "need" C states to be enabled, I just always use them, and it was recommended by Mods on the ROG boards.

Take a look at this guide, it will help familiarize yourself with overclocking with your UEFI.

Seems im running a tad hotter in prime95 now as well. She did bsod overnight and was stock at the bsod screen instead of doing a reboot... could that have fried it?
Just doubled checked.. I hit 86 degrees just now priming for about 10 minutes, Ive not seen that temp before... somethings not right.

Nope that wasn't me that was a random dude he was talking about 2500k I think , different kettle of fish not sandybe , so don't worry about that post. But your problem I have no idea just yet , without another board/chip to test your kinda stuck but if u did u could eliminate these as your issues. Try cooling your vrms or put a fan on the board desk type fan will do , but 1.5vcore@4.375Ghz aint gonna help you eek.gif Don't forget ive got a pretty good cooling setup so LLC is no problem for me.........yet tongue.gif

y u no have my answer....!!!! ARRRG..


i think ive fried either this chip or the motherboard.

Getting bsod x101 at very low overclocks, that worked just a day earlier, would suggest cpu or motherboard would it not.

Unless the psu is on the way out and is under volting something.

Just bsod'd at 4.375ghz vcore ~1.49v in windows...



So becase Im getting bsod 101 errors, Its something to do with the vcore, more likely cpu not being able to take higher vcore, or motherboard not being able to give it?


Have new memory coming anyway, g.skill 2133 4x8 gb, so that will elivate some voltage consumptoion

I was going to suggest that next but you are very madsmiley.png at the moment didn't want to stir u up any more tongue.gif But that would be the first thing to pull out and replace. All my prob solving with hardware entails having spares to swap over till faulty item is found .Im no guru dude. But I TRY to help thumb.gif

1.5 is what I need for 5ghz, you really shouldn't need that much for 4.3. I'd try flashing my BIOS to the latest version and start again from scratch.

That chip has gone to hell man if you need 1.5v for 4.3ghz. You should be undervolting for 4.3ghz.

Manual
yes
normal
1.44

Prime95 doesn't tell you if your stable. Ive had plenty oc's that survive prime95 and crash when folding. It has been stable for 8 months with anything I throw at it so I think it is safe to say it will be ok.
Prime95 but honestly it didn't even push everything as hard as folding. Temps hit alot higher folding.
IBT yes
Didn't run furmark/prime95 together. Thinking about turning it down to 4.625 to lower the voltage. The 4.625 oc only needs 1.39 to be stable and I come no where near maxing this setup other than GPU. Actually, I think I will do that while I am thinking about it.

Update, bios was recently (week ago) flashed to newest version.

I just reloaded all bios defaults for auto everything, stock speed.


3600mhz
idle ~1.01v
load ~1Q#I$H%JKQWEFKNADFNMAKSDFJASDJFLASDFJ



CRASH BSOD 101. Because I dont have extra Ddr3 ram kicking around should I bother even swapping around my 8 sticks to see if they have anything to do with it?

So.... psu, mb, cpu. My money is on cpu. Current system calculated to draw 800+ watts in overclocked form (not counting overclock power req. of video card), However stock system should only be needing ~650watts.... at stock speeds. PSU is Corsair HX750, 8 months old.



at stock settings i did offset voltage +0.08.. results in

~1.112v idle ~35c
~1.320v load ~65c using ~125-130w (reported by coretemp)

This ive confirmed stabled for 3 hours prime95 w/ 90% ram being used, and running IBT at maximum at the same time.

If you have 8 sticks of RAM that's going to put some stress on the IMC requiring more VCCSA voltage. If anything, try removing some RAM and see if that helps the problem.

prime95 isnt the only measure of stability.

Have you enabled the extra options in prime95? The reason folding gets you hotter is because it stresses the cpu and gpu at the same time, hence I asked if you ran FurMark and prime95 at the same time, this will fully stress your system.

As we speak, I just had the system pass 3 hours of prime95 and IBT at the same time. Loaded up furmark and prime again, and she straight up shut down within 5 minutes. I attribute this not to cpu failure but to psu failure as well.

Seems I have multiple issues going on.
