I'm building a budget file server oriented non-gaming AMD system from some new and old spare parts. After low level memtest86 testing the new build, I found that core #2 of my old six-core AMD Phenom X6 1090T immediately fails it tests -- probably its memory controller circuits are damaged -- this CPU suffered overheat after its CPU waterblock failed. I need to find a way to specifically disable core #2 from the BIOS layer.
Relevant specs:
* Gigabyte GA-970A-DS3P AM3+ Motherboard
* AMD Phenom II X6 1090T Black Edition CPU
The BIOS, like many, others allows the user to disable cores but doesn't appear to allow a user to disable a *specific* core. That is, there is a menu that allows setting the CPU into 1, 2, 3, 4, or 5 core mode. You just don't get to pick which specific cores get disabled!
I'm pretty much sure this isn't possible without getting access to this motherboard's American Megatrends AMI BIOS source code then recompiling a new firmware image.
Out of curiosity, would it be possible to get access to that firmware source code and the compilation tools somewhere? Then create a "hacked" custom BIOS that is hard coded to disable core #2? This hacked BIOS may then only work with this system but that's alright. I just presume that if the stock BIOS has a way to disable CPU cores, it wouldn't be too hard to locate that section of code and have it disable a *specific* CPU core only!
I'd be happy to run on 5 cores out of 6. This AMD X6 1090T CPU is over 5 years old and well out of warranty. It still sells on eBay for $140. I'll probably end up getting a brand new 8-core AMD FX Black Edition FX-8320E Vishera 3.2GHz for $130 shipped!
