I have recently flashed a Bios on the L440GX+ motherboard with dual Pen 3 slot 1s. Before the flash, the motherboard would give me an error about the missing Stringe, but still it would load. Now I have an error I cannot bypass. This is: Error 8187: Processor front side bus frequency mismatch, system halted. Additionally, I have the 14.2 and 14.3 bios on a recovery disk which loads properly. but still the issue persists. Any clues?
