FX-8370E not compatible with GA-78LMT-S2P?

[jedievan]

I just upgraded my CPU from a Phenom II X4 965 to an FX 8370E, but now the performance is significantly worse. I have the GA-78LMT-S2P (rev 5.0). I updated the BIOS to F4b. The Gigabyte website shows the FX-8370E on the CPU support list for the GA-78LMT-S2P (rev 5.x) since BIOS version F4b. What am I missing?

No that board is not suitable for 8 core FX chips. It is poor quality even for FX4 chips. It has low power phase, no VRM heatsinks, just not great in general.

Since you already have it though, and I don't think this will make the difference you are looking for because your problem is likely due to VRM throttling, you might try pulling the CMOS battery to reset the bios configuration for the new CPU. Leave it out, with the power off of course, for about two minutes. Then put it back in, power up, enter the bios and reset the option for "optimal default" or "system default" configuration and save setting.

Probably though you will want to get a better board. Something from the 970 series or 990FX series motherboard family that is indicated on one of the three following links as being suitable for FX 8 core processors. Supplies are limited these days since they are not being manufactured anymore so you may have to look at a used board from ebay or elsewhere.
