Hi, I'm using intel desktop board DP67BA. I tried to overclock RAM in BIOS. I just touched RAM clock, not touched about timing at all but my computer doesn't get to even BIOS after that. I tried to reset CMOS by discarding mercury battery for 1 hour bot not worked. I tried to remove BIOS setup jumper, plug in USB which bios file included but not worked too. How can I recover BIOS from my board?
Do you know what bios you had or have now?
Is the i5-2500K something you just added?
Do you have another graphics card you can test with?
Can you test with only one dimm?
In this thread, Scott has a 25 step procedure (for another board). https://forums.intel.com/s/question/0D50P00004VhEOFSA3/how-to-upgrade-dz75ml45k-bios-from-0006-to-00...
Adapt this procedure for your board and bios, and follow it exactly. Do not shortcut or skip any steps. It may work, it may not.
Thanks a lot. I'll try that process with only one dimm and graphic card. Since this board not supports internal graphic, I'll test with graphic card plugged in. I had BA0082 bios before problem.
Also, I tried to boot by from step 14, but not worked at all. Does the only way to fix board is to flash bios chip manually?
Files to flash the chip are never provided. If you purchased such a chip of the net, you are getting some other board's information, MAC addresses, and such. I do not recommend you do this.
You can, if you can find a .ROM file, which Intel never provides due to security concerns.
If you have roached the board, you may want to try and find one on the used market
Also, the latest bios for your board is 0083. The release notes can be found here:
I have attached the latest bios in case you do not have it.
Test with G2020,
1) without connecting fan, bios cfg jumper plugged = infinite loop 10 secs on and off
2) connected fan, bios cfg jumper plugged = on but no screen
3) connected fan, bios cfg jumper unplugged, usb bios file included = infinite loop 10 secs on and off
Can you feel something? If you need, I can try with another processor
G2020 Ivy Bridge processor with connected fan, bios cfg jumper unplugged, plugged usb bios file included now not reboots. Can it be bios recovery process? Do you suggest me to wait?
Sadly, I don't have another power supply that can use for this system now. I only have a lot of sandy/ivy bridge processors, two graphic cards and 4 rams.
