Sapphire A9RD580 Bug/Issues/Fixed

[xs64]

Hello everyone , who owns a Sapphire A9RD580
I create this topic to discuss about this mobo : bugs , how to fix , trick ect

I have this mobo for about 2 weeks , and got many issues with Bios
As far this mobo overclock very good , but the Bios has to be improved and fixed
And i tested with all Bios in Sapphire website ( 0403 , 0411 )

Ok , let's go

*1. PC will not turn on everytime you turn it off , including turn off your PSU or not. At this time clearing Cmos is your friend ( i did it too many times that cant remember in 2 weeks )

*2. With divider 200 , when you set Trwt-Twtr-Twr = 2-1-2 , it will auto change 3-1-2
With divider 166 , when you set Trwt-Twtr-Twr = 2-1-2 , it will auto change 2-1-3

*3. Divider 200 : Tref will be : 200 3.9us
Divider 166 : Tref will be : 166 3.9us
And U cant change this Tref in Bios

*4. In User Config Mode , only these settings can be adjusted : Max Async , Read Preamble , DDR Drive Strength N/P
The others cant be adjusted , they will not change or make PC not boot

That's all the issues of Timings setting

*5. Issues of LDT Freq.: cant set 5 when HTT is over 280 , you must set it 4 for HTT 280 --> 340 or more . Even when you pump up HT Link Volt , PCIe Volt or CFx3200 Volt ect

*6. One more issue is the Vcore :
Better not adjust CPU Vid Control , just leave it at DF and adjust the CPU Volt Offset
Or you must set CPU Volt Offset = 0.24v , then adjust CPU Vid Control

And for sweet Overclocking your CPU , i recommend these setting

First , leave the HTT bus at DF , set RD580 HT Drive Strength and RD580 HT Receiver Comp. = 31 , RD580 HT PLL Control = Fast
And then turn off PC ( PSU too )
Then turn PC on , start raising HTT ect

And even chipset RD580 is not too hot , but the passive heatsink of Sapphire seems too much hot , i cant touch the HS in 3 seconds ( about 80°C at full load without airflow )

Also there is no Software can monitor Temps , Volts ect. ATI System manager can only adjust HTT , no more. This is very annoying for end-user who hope this board can OC like hell

Maybe there are still some bugs that i have not faced them. So please feel free to report.

Best Regards.

ps : sry for my poor EN

Update :

Ok, Speedfan does work if started with the /NOSMBSCAN option. At least I can now somehow check my CPU temp on this "great" overclocker mobo....
