Can u really unlock the Phenom II x2 555BE with GA890GPA-UD3H mobo???

hi guys and I really need professional help on this one... planing to buy a system.. from Malaysia so over here hardware is overpriced... so Im going with a dual core but wanna unlock it... but also want a mobo with the 890GX/FX and the SB850 chipset.. so i choose the gigabyte's GA890GPA-UD3H. decent voltage reg. for overclocking with a 4+1 phase power design but I cant find anywhere on the net about its core unlocking abilities... so if any of u guys out there have sum info pls share it here as well...

Thanks,
Navin Raj

ouh and also what is the diff if I hav a crossfire with 8x 8x option compared to a 16x 16x option?? does it really matter cuz i plan on doing crossfire with 2 HD5850's

Don't think so, AMD removed ACC from the SB850 chipset and thus you won't be able to unlock cores with most 890GX/FX boards. There are some manufacturers such as ASUS, who have implemented a feature called 'Core Unlocker', which well, unlocks cores if they can be unlocked. Unfortunately the GIGABYTE GA-890GPA-UD3H does not have this ability.

With PCI-e lanes, 8x/8x offer half the bandwidth of 16x/16x, although you will see very small performance impacts, as in < 5 FPS or so, with a card like the HD 5850. With bandwidth munching monster cards like the HD 5970, you'd definitely need a 16x lane.

Actually on the GPA versions don't have core unlock the other gigabyte 890 series boards do.
