The specs say "An SMbus interface allows full control of the device"
Nice. Why is that showing maximum PLL oc at 280MHz?
This is a dump of the smbus registers "i2cdump 0 0x64 s"
Code:
   0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef
00: 07 ff f0 ff 00 00 62 01 14 e0 e0 54 7d f8 17 de    ?.?...b????T}???
10: 76 f8 17 04                                        v???
The specs say what those mean. Gotta figure out how to read those registers from within a kernel module. That module will provide devices in /proc or /dev whom can be used to read(write) the values.
I'm still very busy at work till june. Have two weeks holiday then and will work on that module then. Meanwhile i'll do some theory (reading other sensor chip module code and stuff at smbus.org).
Where's the register encodings mentioned? I've not come across them yet, would be cool. Thanks.
I guess windows does not use the downcore method for unused codes so it will run at 3GHz but do nothing (beside freezing maybe).
On the M3A I disabled cores 3 and 4 via bios and had no freezing issues at 3GHz so I assume disabling via bios is save.
A good test case should be:
1. Disable all cores beside core0 and find the higest voltage and frequency the core can handle. Use the higest voltage as the top limit in 2.
2. Add cores1-3 individual and find the highest voltage and frequency for that core.
3. Use the minimum of the max voltages of all four cores and find the max frequency for each core at this voltage.
4. Enjoy your overclocked system
Yeah I'm going to test something similar.
I hope it was due to your multis this time.
Yeah, speed was unstable

MSI and Abit, nothing else yet. Haven't had GBT DQ6/DS5 for a long time now, but do have GBT 740G and 780G boards.
Borrowing spare MSI from work friend, mines dead.
