outdated motherboard

i recently installed a samsung 850 pro 256gb into my desktop computer, which i built 7 years ago. i was disapointed at the read and write numbers [380-350]. the problem is the motherboard. it is a msi 870a g54. it has no settings in the bios from ide to ahci. my cpu is phenom ii x4 955 be. the ram is ddr3. recommendations would be appreciated. i'm thinking of replacing the motherboard. newer boards have am3+/am3, but have ahci option. please comment. i want to make sure i'm making the right decision.
thank you pothound

Is the MB able to run sata 3 if its only sata 2 that will slow it down

Seven years old man that is a long time you are better off getting a Combination package if your going to upgrade the Board a 955BE is pretty damn old

I would look into a 990fx Mobo with a new CPU too

AMD Processor Motherboard Bundles | Micro Center
i would look at these deals might as well go full tilt and make your PC is good as it can get without going to wild of a budget

hi motherboard has 6 sata 3 connectors. the gigabyte mb looks good, i was looking at the 970a version if it will work. i have been in the bios a dozen times trying to change to ahci,and there is no option, except in raid. this version is v17.7. v17.8 will offer the ahci. i called msi to see what they had to offer, and they discontinued this old model. he sounded very discouraging. i built this only 6 years ago. technology is moving so fast. i welcome any other ideas. thank you pothound

According to the specifications:
870A-G54 | MSI USA | Motherboard - The world leader in motherboard design

Your motherboard supports SATA III, 6 Gb/s. You can't do any better than that on SATA. That's the most up to date and current SATA there is. You say AHCI is not supported on v. 17.7 but is on v. 17.8. I find that difficult to believe that a SATA III controller would not have AHCI from the beginning, but.... Well according to this webpage:
Support For 870A-G54 | MSI USA | Motherboard - The world leader in motherboard design

The most recent version of the bios is 17.20!

So, why not just update the bios and go in and change the SATA mode to AHCI as shown in the above video and screenshots?

If it were me, I would not upgrade just the motherboard only unless I was going to upgrade other components as well. There won't be much gained by upgrading the motherboard only with the same processor, graphics card (if one is being used), and SATA III SSD.
