I was losing hope with OC stability with these last two most recent BIOS updates. Then I tried something I hadn't since I first started OC-ing my setup a year ago. I did +0.001 for Adaptive and +.011 for additional voltage. This gives me 1.46v under load. Which so far is stable (so far...).
The kicker? I was running between +.005-+.010 on Adaptive for 1.151-1.156 and it was NOT stable. Both OCCT's Linpack solo and PSU test would crash/lockup/fail within 15-20 minutes. Temps were higher.
Running this lower voltage seems to be very good so far....OCCT PSU test is a very good load...especially with my GTX 770 pumping hot air into my case....between that and my CPU none reach more than the hi-70's at this point. I'm pretty stoked about it. I'll be super excited if I am running lower voltage than ever for the same OC!
I was testing this offset (additional voltage) a moment ago and then remembered your post.
It passed both mini stress tests (RE5 - variable test, lower reso -cpu bound & LP2 - variable, same settings) and 3dmark physics 3-4 times, 1-2 days earlier it would fail in RE5- 2nd or 3rd part really quick, if I had additional - auto and turbo 1.275v.
I remember I use to pass 4.7ghz @ 1.258v, I posted it here once, but later I found out its not really it.. Although I didnt use more then 0.010 additional voltage.
Now, I set additional 0.018v and turbo adaptive 1.250v making total ~1.268v, coreV max 1.280v.
And it passed all mentioned above
, but in idle its now @ 0.737v instead of 0.712v
Funny stuff, I think this offset additional voltage acts as a buffer for each turbo multi & its voltage and so if a chip is programmed to run idk 4.6ghz between 1.20 -1.24v (upper values - stabler) you raise this gap a little so now you can use less main.
But I get higher temps now, *see bellow use to get max 62-65C on core0 in RE5, 3dmark physics temps are around the same - usually near70C threshold..
I also have cpu current 130% vs 120% its just that 4-5C gap, will test that again or maybe go for even lower cpuv
, but I think 1.25v is kinda the limit for sure
