First we take a look at the BIOS System Overview of the default configuration and after UCC is turned on.
Using BIOS L1.53, the BIOS isn’t able to detect the name of the unlocked cores. It only shows as “AMD Processor model unknown (64 bit)”. The L1, L2 and L3 cache size do differ. From the original X4’s 512KB L1, 2M L2 and 6M L3, the BIOS now detects it as 768KB of L1, 3MB L2 and 6MB L3.
When the system boots up with the UCC enabled, the Count number of cores shows 6 instead of the usual 4.
