Motherboard, Bios or RAM?

Question

BIOS

installed the old kingston plate again in the ddr3-2 slot (second from the left) and flashed the BIOS as it should be through the BIOS on its factory (f1), after the reboot, the BIOS screen appears for 2-3 seconds and the reboot cycle occurs, without doing anything, I took out the old Kingston plate and put a plate in the first Samsung slot on the left, the computer started up like a new one to the desktop, when the opera was rearranged back, the same thing was like a Bios gathering, the battery did not help, I decided to close the contacts on m_bios to enable the error and flash it to the backup, having done so, it worked on the old one opera, but after even more manipulations, the new Samsung opera stopped working in the left slot, help me figure out what the sore is, I want to try flashing the BIOS with a programmer (which one is better?) The PSU has nothing to do with it, it's the same on a powerful one. It turns out that Bios remembered both the first and second plates,

Answer 1

0. Lean on Russian. Read literature. Finally, get a tutor. It will be more useful than your computer torture.
1. Stop torturing the BIOS. No need to sew it with any programmer. Update to the latest version and leave it alone.
2. As I understand it, the problem is that two memory sticks do not work at the same time (old and new). The options are:
a. They are not compatible with each other. All are incompatible. It happens.
b. They are not compatible with each other because they have different CL timings (which, by the way, you did not specify).
in. You have some RAM connectors broken on m / b - therefore, when rearranging from one connector to another, the memory either works or not. Perhaps not broken, perhaps they just need to be cleaned of dust.

Answer 2

With a high probability, the problem is in the motherboard
. With some chances, this may be a mote in the connector, since a memory chip that works in one slot does not work in another
