Hi folks,
I just flashed Coreboot 4.3 release on my F2A85-M (the "original", not Pro or whatever) together with Seabios and the VGA ROM. I am running the "bare" board with an AMD A4-5700 APU and two 8GB Corsair Sticks () at 1,5V. No attached peripherals except an usb stick which I use for booting a live system. Unfortunately, I experienced the following issues:
(1) When I plug the memory sticks in the black DIMMs I get no Video, although they were working fine there before with the vendor bios. However, they "work" when inserted in the blue slots. (2) I am getting errors im memtest86+ 5.01 in compatibility mode in mem adresses around 3700M. I tried both sticks, each also in single configuration but the issue persists. I had no issues with the vendor bios (when inserted in the other slots). (3) The CPU temperature is reported wrong in Memtest86+ (Memtest86+ reports 15°C while it was around 35-40°C in the vendor bios at around the same fan speed and environment conditions). However, I don't remember if it reported a correct value with the vendor bios.
The memory sticks have been reported as follows by the vendor bios:
Handle 0x0035, DMI type 17, 34 bytes Memory Device Array Handle: 0x002F Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 4096 MB Form Factor: DIMM Set: None Locator: DIMM_B1 Bank Locator: A1_BANK2 Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1333 MHz Manufacturer: Corsair Serial Number: 00000000 Asset Tag: A1_AssetTagNum2 Part Number: CMZ4GX3M1A1600C9 Rank: 2 Configured Clock Speed: 1333 MHz
Are these known issues? Or maybe just a false alarm?
Cheers, Daniel
