I received new replacement Optane_900p, last night during 1usmus memtest in progress, I up the SOC voltage from 1.15v to 1.2v and Dram from 1.36v to 1.38v and VTT from 0.68v to 0.69v using A-tuning and PC crash instantaneously.

Power off power on no BIOS no windows. error 33, 7b, 6a, b6 again.
Rear button clear CMOS not working. error 33, 7b, 6a, b6 remains.

with so many previous experience I took out the Optane_900p from slot-2, power on and BIOS appeared.

Hope ASRock bios team next release can help solve this. Thanks.

use the ryzen dram calculator


Hello da tony b,

Yeah, of course I am, just not lucky, am in process of using 1usmus calculator only as a guide then change here change there many trials effort ahead.

BTW I'm no longer using the Corsairs CMK32GX4M2B3000C15, but Hall of Fame 4x8gb with Zen2 the experiences from Corsair+Zen1 completely different and not immediately useful.


hello mate

im still rocking samsung b dies in tridentz

glad i picked them up for mega mega cheap when a major u.k. retailer went into liquidation

im stable at 3600mhz cl16 on bios 5.8 with the 3800x

i just cant be bothered to set any 'show-off' speeds and timings these days , i spent so much time on the r7 1700 when we first got our boards to get some good ram results ,its kinda pointless now with the 3800x and 3600 ram

Thank you @ASRock bios engineering team.... x370 taichi bios 6.62 solve boot loop 33,7b,3b,b6 !!!!!

Thanks features
1) Dr.Debug appears on monitor - wow - so convenient !!!
2) settings storage memory slow increased from 5 to 10 !!!
3) voltage increase at steps 0.001v for SoC, CCD and IOD !!! amazing !!!

I've been using 6.62 for 2 months now, all good.

Can overclock ram to 3800mhz and FCLK push to 3800mhz but no boot on my CPU, but no more 33,7b,3b,b6 !!!!!

sometimes it would shutdown and reboot 3 times and recover to 2133mhz.

sometimes it stuck, but I can easily power down and power on, no need to clear CMOS button at rear. So convenient now !!! thanks !!!
