Posted - 02/28/2013 : 15:29:36 Today I got the GQ-4X Programmer. I have a good data chip (AM27C020) that I need to copy. I placed the chip in the burner (selected my chip), and did a chip read. Then I saved the data as a .BIN file. I then put in my new chip (selected my chip)and did a blank check - (OK). I then did a write. It wrote and verified but when I try it in my motherboard I get nothing. What am I missing? I've tried writing to several chips and the same thing happens. All pass the blank chip test before burning. |

Select the device type and then read the orginal chip.

Posted - 03/03/2013 : 07:09:49 When I read my original chip I get a good checksum. When I put in the blank chip and change the device type, the checksum changes and I get a bad burn. I was able to get 2 good burns out of about 12 chips. What might be the problem with the bad checksums? |

I think the data is not read correctly. Make multiple read and make sure all checksums are the same, then save it.
Also, try to use slowest speed and/or an external power if the original chip is a old chip.
