Great site. Hope I can solve problems myself eventually, but for now I bring you the below.. issue.
OCZ ReaperX PC3-10666 DDR3 Memory (2x2GB Sticks) fails to work on some/most of the BIOS' for the Foxconn X38A Motherboard. DDR2 Memory works with no problems.
The BIOS version that possibly works (linked) is from November 2007 and not updated for the E8500 and similar line of CPUs.
Is it possible to have the memory "options" from the D24 BIOS coupled with the CPU compatibility/other updates from the P14 bios?
Also: Very Limited success setting BIOS options under DDR2, then powerdown and replacing with DDR3 before powering up. Any way to set some Default Values? AMIBCP313 does not work with P14 or D24 bios.
I would guess that the E8500 compatibility comes in the form of one of the "CPU Patches" that have been added to the P14 bios? I see the D24 has 20 so patches, whereas the P14 has 24. Can I just add the CPU Patches from the P14 to a modified D24 bios to have it "updated"?
Edit: Found out the CPU Microcode updates for the E8500 were for CPUID 0676, platform type 01 and 10. The D24 has them in Revision 06 and the P14 has them in Revision 0C. I guess should be able to use the 0C Microcode updates in the D24 bios.
Looks like: ID 55, 1B, 21 and 11 have the ROMs changed between these updated BIOS versions (and between most others). Just a shame the change log from Foxconn state very little about what has changed. Always been under the impression that the latest version is recomended, except in this case it will not work with DDR3 :\
We users do not have the software tools or knowledge to make DDR3 work on any motherboard. Even if it worked on earlier BIOS, the code is extreamly complex as it is generated by some high level BIOS Editor and not by hand in assembly language. It might take a lifetime to figure it out, if ever....
As I understand it, the CPU microcode module can be inserted in a older BIOS to pick up CPU support, but I never tried it. Make sure you have a spare BIOS chip as BIOS corrupt very easily. MMTool latest mod is the program to use for replacing BIOS modules.
There is actually very little that we can do in BIOS modification and if I don't have the exact board up and running, I can't do anything....
