could i ask you to fix the temperature readings? master software works just fine but when bios is controlling fans and it reports it as 75 when really its 55 the fans sound like jet engines

My 1800X needs 1.306 V SVI2 voltage after droop to run ITB AVX stable at 4.0 Ghz. At LLC0 I need to setup 1.4 V to achieve that. Using P state OC using 1.350 V +.0.050 V ooffset results in 0.006 higher output, aka one tick. Good to know.

thats pretty much the same to get Realbench or Prime95 to not shoot out WHEA errors for 4ghz. For me that is 1.35 (auto) and LLC2.

IBT AVX standard, high, very high or maximum?

Set the FID of p0 to a hex number suitable for you, 98 is 3.8GHz for example. You can see the frequency on the right side. Change the applied voltage under "Extreme Tweaker/CPU vcore/offset" to something suitable for your chip (default for non-X is 1.18V (add +0.15V for 1.33V), for X it is 1.35V (add 0V for 1.35V)).

Is this available on BIOS 1002 because I don't see those options under Advanced in BIOS.

EDIT:

Never mind, I see it. Thanks.

I get a lower Cinebench score with 3200mhz ram on my 1700 @3.9Ghz 1.35vcore (1610) points / than ram@ 2933 and 3.9ghz @1.35vcore (1640), whats the issue? also if i have Higher Vcore 1.4 @ 3.9GHz i get (1652) points with 2933Mhz ram Its confusing.

oh and when doing intel burn test on standard my cursor lags heaps then frees up, is this normal?

Updates on my progress:

Settled on my 4.1GHz CPU OC, and moved on to memory. My video card doesn't seems to like me messing with BCLK too much, so I went looking and found the BCLK 100 - 3200 - 18-14-14-36 setting some people were having success with.

It seemed to work alright, but I was getting consistent errors in y-cruncher (even IBT Very High was working alright). After messing around with a bunch of parameters, I've found what worked: lowering ProcODT to 48. I've seen lots of reports of increasing it to 80, but to me that made things much worse (which helped point the right way).

Currently doing a longer batch of mixed stress tests to make sure it's properly stable (I do math heavy workloads, can't have silly math errors popping up).

Current setup:
1800X - BIOS 0081 - BCLK 100 - P-State 0 to A4 (4.1GHz) - LLC Auto - vCore Offset +0.1125 - VSOC 1.15
RAM F4-3200C14Q-64GVR (4x16GB) - 3200 - 18-14-14-36 - VDDR 1.4 - VBOOT 1.4 - VDDP 1.0 - ProcODT 48

I think I'll try to shave the DDR voltages back to 1.35, maybe lower the VSOC a bit too, but I think I'll stop messing with the RAM until the next AGESA comes out. Good enough for now :-)

Is your processor throttling? Is your memory running at 2T vs 1T or looser timings at the higher speed?

I just got a 1712 Cinebench @ 3.9 vcore 1.4 And Ram is 2933Mhz - 16,15,15,36,69 @1T With win 10 creators update., and I just found out now that running Ryzen master at the same time lowers your Cinebench score by about 20 points. Also how would i know it's is throttling?
