Suitable, but RAM does not start. What to do?

Question

RAM

Please help... I have a board ms - 7529, which only supports ddr2. I found a 4 GB ddr 2 pc2-6400-cl6 800 Mhz stick. It looks like it should fit. But when you start the PC with only this plate, there are three long signals without a picture on the monitor. What to do ?
I tested it on another PC and it works.

Answer 1

I recently bought DDR2 modules on Ali, and noticed a warning from most sellers - this memory is only suitable for AMD processors. However, sometimes there were modules about which it was written that they were universal. Perhaps this specificity is the cause of your trouble.
Check, make sure, and if this is the case, then it is easily overcome - you need to exchange the module with the owner of the AMD processor.

By the way, now it is a rarity. There was only one seller on Ali offering 4 GB DDR2 modules. Naturally, they are only for AMD. And they are also very flimsy - having bought two, I ruined one of them, not sticking it into the slot until it snaps into place.
