@jhononweed Yup, I had earlier tried increasing the voltage of RAM and SOC, and also "relaxed" the timings but not after this latest update which fixed my crashing issues. I'm not inclined to OC anything really so probably won't try bumping things up again. I had managed to boot my 2133 RAM at 2400 speed earlier but not more.
@Jasku the 2933 speeds you mentioned I guess people with higher rated speed RAM like 2600 to 3200 or more were able to pull off. I could only manage 2400 with my 2133 rated kit earlier. Agreed, yes, if you pay for high performance RAM like 3200 then you should expect it to work at full speed and maybe with some OC headroom.
I guess everyone will be waiting and watching for further BIOS updates as AMD has mentioned in their community post update that we can expect to come next month which should further improve the RAM speed/stability situation.
And yes, by now it has become common knowledge that ideal RAM speed is 3200 (and maybe more) for the inter-CCX infinity data fabric communication performance benefit to be optimal. But I don't really care too much for squeezing out that extra bit of performance, so I'm OK with plain old 2133 standard RAM spec on standard 1700 CPU clocks
