I have an Asrock x99 oc formula , my bios is same to yours.E5-2683 v3 BIOS settings
'Max Core Ratio' needs removing as it is irrelevant for this CPU. Long duration still reverts to 120W but use false reading to bypass this otherwise limited to a RAPL of 40 seconds. Use to run BCLK at 105.1MHZ but saw I was getting a lot of corrected WHEA errors on the PCIe bus with NVMe at of 103MHz and GTX1080 at ~102MHz. Can reduce with lower link speed but just doesn't seem worth it for a few percent.
Can hit max turbo -1 with AVX2 and -20mV offsets but seems to ramp up over a few seconds from max turbo -2 to -1. -30mV gives much faster response. And yes, VSA is positive.
Most likely could lower DRAM voltage but haven't bothered. Timings reduced.
OC lock is being used for power reading and not OC lock. Need to change if I get some enthusiasm back. Tjmax doesn't do anything here and some other settings such as "Perf_Plimit_Differential" which if I guess correctly is actual for dual socket and P-State differential between sockets. Maybe I'm guessing wrong.
Could add package C2 here but PC2 doesn't seem to make a lot of difference.
Anyway that's what I'm running and works for me but might not work so well for someone else. Needs a fair bit more work yet, maybe some time later on.
Edit: Thanks Cata40, hope imgur works better than Photobucket did
Why you have v3 configuration and me not in bios?
