post #3761 of 10702




Notice in the first screenshot how vCore is set manually to 1.250V, yet in the third screenshot it's ramped it all the way up to 1.33V!

When running the exact same settings at a lower multiplier, the voltage behaves as it should and constantly runs at what I set it to. But at 41x, it wants to give the CPU tons of voltage despite it not being on automatic.

What do?!



EDIT: Hmm, without LLC it runs at 1.28V under load and 1.34V at idle. That's with it set to 1.25V. So the problem still exists that it's not running at the right voltage, but LLC just makes it worse.

Something is weird with them because I cannot reliably pass 1792 on its own but I recently ran a 18 hour blend test which went thru 1792 multiple times.

I understand you want a quicker solution. I spent considerable time testing both for stability so I know how much patience and commitment it takes. But like most things it takes effort to get the best results.

For the vccio I found that just a notch or two above stock was best, I run 2 sticks of ram, 8gb @1.5v. There are a lot of people that told me to raise it to 1.15 but I have serious problems when I start getting up to 1.12. Just use what your CPU/RAM/IMC respond best to, start from stock and increase notch by notch up from that. 1.17 is really high anyway and I don't think thats a great idea.
For example. I can pass half an hour of 1344 and 1792 with 4Gb of RAM using -0.015. But it fails at regular blend around the 10 hours mark.

12 Hs is the only way-

Are you sure that it is really stable? It looks like you have been running prime for about 6 minutes, and it is easy to fail after a few hours.

I wouldn't really call an overclock stable until it has passed 12 hours of blend.

Maybe try clearing CMOS? It might be some kind of bug in your BIOS?

try clearing the CMOS and use HWmonitor to view the voltage, or gigabyte's easytune, that has a tab for hwmonitor.

Sorry bud, but not sure if you're looking to get into the club, if so please refer to the rules in the OP.

Thanks

Hmm so I've been thinking for the past day. If I can't change my voltage manually while it is set to offset mode, if I bump my OC up to 5Ghz I wonder if the voltage will scale up? Time to do some testing!

just becareful when switching between offset and manual!!!

IMPORTANT INFO FOR ASUS P67 MOBO USERS

The member quoted below killed his sb chip through a bug in Asus's bios. It is apparent that switching between profiles mainly offset and manual) the voltage does somewhat get altered. As pointed out, this bug is very dangerous and I do always recommend checking settings before applying but nevertheless this bug should be a top priority for asus.

So 1.24v+.975v=2.215v

Happened to catch it last night before I saved and exited my 5ghz +.105 offset, the offset was actually at +.975v.
Had I not checked...

So be careful and always double check the offset when switching saved profiles.
Here is the link to the actual thread. LINK

hey munaim, after lowering my llc to high, i stopped getting errors when my cpu would take on a load, so I think ultra high llc provides too low of an idle voltage for my chip, as when a load is put on it, p95 immediately fails on a core or 2... switching to high and changing my offset a bit remedied that...

Well that was interesting, I set my OC to x50 (5Ghz) and I did the 1344 FTT and about 15 minutes in I got a x14 BSOD. Oddly enough the temps were about the same, but even more weirdly the VCore stayed at around 1.400vcore.

Question, do the Manual and Offset settings work with each other? Like if I set my VCore in manual to 1.3v and then switched to Offset, would it max out at 1.3v?

no, with Offset, the LLC setting defines how low voltage can go. for instance when my LLC is ultra high, my idle voltage is below 1.1v and i get crashes when taking on a load. When i switch to high, my idle voltage is a touch over 1.1 voltage and i'm fine.

The vcore is kind of wonky as well, scaling up really high for small values with ultra high llc and then scaling up much smaller with larger values of llc. make sense?
