Plissken Do you guys install the Asmedia USB drivers found in the C6H download page? They are 2 years old... strange thing is that both the C7H and C8H doesn't have them in their respective DL page. I have uninstalled them though and let Windows 10 use its own USB drivers... what do you think?

For both instances I've used the 1usmus Dram calculator v1.62. I also saved my timings from previous bios before flashing to 0075 and compared the timings between both bios and timings are almost identical. Is this a bios difference or something I'm overlooking when transferring timings from calculator to bios? Btw using FlareX [email protected]


Cheers
most likely some AMD CBS setting that gets disabled on the newer bios which causes the performance drop. that or you need to set all the timings in the dram section manually (and I mean everything) since they affect some hidden timings which you can't tweak via bios.

seems normal. I think thats how they boot with higher memory voltage.

Same issue here with bios 7501.

datspike I've got another 3600 to test, so there are results:
105 BCLK, PBO MAX, 10X, BCO +200
Spoiler!

R15 213/1721

This cpu has some issues running high FCLK (1833+), I'm getting freezes every 2 minutes or so when cpu is warmed up in games. Will test today if increasing vsoc/vddg helps
It can post anything up to 1925 FCLK tho.

Are you using the 0075 beta bios? It shouldn't happen with that one. Also, having a DRAM Voltage Boot settings other than "Auto" can also cause this.
