The motherboard also offers 4x 1.5V DDR3 DIMM socket that supports memory up to 32 GB.
Hi Guy's, Since April my New PC has been working fine.
Then I re-downloaded Portal2 off Steam onto the Computer.
The motherboard offers advanced 8 2 phase CPU VRM power design for high TDP CPU support, 2 PCI-E 2.0 x16 slots for ultimate graphic performance using the two graphic cards at the same time.
The motherboard has AMD 970 North Bridge and AMD SB950 South Bridge chipset.
Then I found out it was a problem with AMD's Bulldozer CPU's and that the only way to fix it was by updating the BIOS.
So I updated BIOS successfully with Gigabyte's Q-Flash.Maintaining updated Gigabyte Socket AM3 GA-970A-D3 software prevents crashes and maximizes hardware and system performance.Using outdated or corrupt Gigabyte Socket AM3 GA-970A-D3 drivers can cause system errors, crashes, and cause your computer or hardware to fail.After pressing reset power buttons together for ten seconds MOBO is booting old backup bios, and after few seconds I can see the message: "Warning: MAIN BIOS CHECKSUM ERROR! Everything works fine with stock F7 version, system is booting without any problems, memory oc to 1600MHz works fine.My configuration: Gigabyte GA-970A-D3Phenom II x4 945 3GHz2x 4gb Corsair 1600 DDR3 ram Gigabyte Ge Force 660Corsair SATA SSD 120 GB drive Chieftec 550 W PSUI tried few bios versions from gigabyte's official site, downloading from different servers, also once from @bios application F10 version of bios, all with the same result as I've stated before.He is a lifelong computer geek and loves everything related to computers, software, and new technology.
