I can't remember the Model of his MB,gonna see that one tommorow buddy.
Unfortunately the most important part of that pic is flushed out by the flash, the exact model number on the old memory.
So H55M-E33(MS-7636) is his MB
the model number on old memmory is CMZ8GX3M2A16009C
on the new one its CMZ4GX3M1A1600C9.
I also updated his bios but still the pc keeps rebooting when i insert this new ram.I dont know what else to do.
So you're going from 8 gb to 12gb? There is 2 issues, 1 is adding only 1 module you aren't really adding performance as you are no longer running in dual channel. Secondly is that while the specs are the same the model is slightly different and while they "probably" should be the same, they likely are not. Maybe they have a different chip layout or different chips manufacturers. Either way that is the issue.
picked as solution by mistake
no buddy i am trying to add 4 GB so that would make 8 GB in totall,hes old ram is 4GB not sure how you got to 12 there,but anyway think you may have a point with the chips.
Ah ok, when I put that model number in I found an Corsair 8GB kit:

It seems that when the PC was built a kit was split up to get that 4GB, as the model numbers are always unique between kit vs single.
Either way you have 2 different models which explains why it doesn't work together. As well Corsair memory at 1600 was not tested on this motherboard, so that particular model you bought may have a compatibility issue, whereas the one you have luckily worked. Either way if you want to go to 8GB I would say buy the kit I linked, or buy another of the new memory you bought. Mixing model numbers sometimes can work but usually doesn't, same with brands of course.
