Okay this seems to running into the part where so many whom had an MSI AMD board began to argue about why some of these boards burned or blew-up well maybe not a literal explosion but the mosfets sounded quite loud when they were overloaded and the silicon was ruined.
That board seems to have done some 'evolving' into different components for the manufacturing.
First > 870S-C45 with 870 type chipset and n0 support for later Zambezi/FX-series processors.
Second > 870S-C45 (FX) with 870 type chipset and support for later Zambezi/FX-series processors; as indicated by the (FX) in the naming of the mobo.
Lastly so far > 870S-C45 (FX) - V2 with 770 type chipset and support for later Zambezi/FX-series processors; as indicated by the (FX) in the naming of the mobo. So although still named an 8XX type chipset mobo, it is said at MSI site to n0 longer even have any form of 8XX chipset.
Since these cheap entry level boards were said by MSI to support the later 6 core Thubans and now the FX-series but users had issues with pushing the boards and the boards failing dramatically and MSI even saying at their website not to run burn-in tools on some of these cheap entry level mobos, "but" still wanting to sell them to the unsuspecting as ready for all the AMD cpus including the power hungry AMD FX-series, they have made the bios n0n-Vcore adjustable and let the motherboard do all the Cpu Voltage adjustment. By doing this they can keep a user from dialing in a lot of cpu voltage and pushing the board like they did last year and having pretty dramtic failures of the VRM circuit.
A final couple of thoughts: I have looked and looked and found n0 review of this cheaper MSI motherboard, to see if they had a bios picture. I can find them for what they consider their better line of mobo's but nothing for this cheap entry level mobo.
If you are experiency high temps and believe it is from Vcore that is higher than just necessary, I expect you will not find any setting in the bios on the board since they have said it now works with FX-series processor. They do not want you messing with the Vcore and harming the VRM circuit to the cpu. So you can get better cooling or another motherboard more suited to the FX type processor or live with what you have.
There is one other thought that intrigues me and that is you as an owner, can contact MSI support and give them your make and model and revision of motherboard and even the serial number and the bios version you are using and ASK them where the Vcore adjustment is located in the bios version your are using with the FX processor in the cpu socket. I really wonder what sort of answer they will supply when you give them full details of the board in use.
