Nope..no way to set multiplier.. BUT at some other forum someone tried to flash the K9N Neo (7260 ver.1.0, NVIDIA ® nForce 550 Chipset) that I have with the bios from K9N Platinium (7250 nForce 570 Ultra Chipset)
Apperently this worked and gave the multiplier settings.
BUt why dont MSI enable this setting for the K9N NEO ?
5000+ Black edition is supported on the 7260 (Neo) according to MSI and thats why I bought the CPU but you can change the multiplier! Can it be any technincal reason (between nForce 550 and 570) for this or is it just some marketing ****?
