[hacker007_bio]

Hi
I have a gigabyte H61M-S2P rev. 3.0 motherboard with i5 3570 and 4gb ram. I recently upgraded my memory with a single 8gb 1660 memory module and pull out the 4gb one.
before this upgrade PC was OK but after that, I experienced some problems such as :
1- during boot sometimes motherboard beeps (same as the beep of RAM problems ) with no display and after pressing reset button it boots normally.
2- sometimes its reset suddenly

I use win10.
both modules are king max brand.

please help me with this problem

Try to boot with your old RAM, if they working fine, you have to suspect the new RAM

there is no problem with my old 4gb RAM.
8gb module is brand new . the thing is the problem appear often but not always...
if the RAM is fully How the computer can boot with it ??
I also checked that with "memtest" and "win memory diagnostic tool" in boot and no problem found.

sometimes when u boot ur pc and something is putting pressure on the spacebar there can be a beeping sound so check if thats anything to do with it.

What kind of "beep" do you get ? That will indicate what is your problem.
And what the detail spec of your RAM ?
