Pc shuts down after few seconds of starting

Windows is seeing them as 2GB each, get into the BIOS and see what the motherboard sees them as.

if the boot loop only happens when all 4 chips are in their slots, maybe it’s a dual memory channel thing.
your RAM slots are probably coloured, with 1 & 2, and 3 & 4 being the same - or 1 & 3 and 2 & 4 being the same.
only have two sticks in, and put them in the matching colours. it’ll only use single channel mode but see how that pans out.

Ok, i put the 2x 8gb rams in slot 1 and 3 and once i get to the desktop, i checked under performance in taskbar and it shows 1 slot out of 4 is occupied. Checked my system memory, says 2gb. The bios say 2000 mb of physical memories. then i shut off the pc; switched from slot 1 and 3 to 2 and 4. Start it back up, went to bios, physical memory is at 4000 mb. Save and Exit. Went into my desktop window, checked under performance, slot used is now 2 out of 4. Checked my system from system and security, installed ram is 4gb. I just dont get how 8gb stick turns into 2gb, is there a memory leaked or something? I just ordered a new mother board, coming in next week but i want to see what the real issue is.

Is this considered as 2gb or 8gb? Its what i used.

and the new mobo takes DDR3 sticks?
and those current sticks are compatible with the new mobo?
memory is pretty cheap at the moment, I’d lash out and get 2 new 8GB sticks as well. (but that’s just me)

so despite this memory GB not being what you want - are we past the PC boot looping? (as long as the right stick is in the right slot!)

yes it would be nice to know what the real issue is, but sadly, with hardware, that is seldom possible without actually replacing parts first.

and dumb question - you are sure the PC used to read it as having 16GB’s ???
are all the sticks the same make/model/capacity?

Never really pay attention to the rams, i just assumed they are 8gb stick. Yea i figured out why my pc get the boot loop. The new motherboard is same maker just newer version. Bought 2x 8gb sticks now, hopefully they are 8gb, not 2gb. Guess you can close the thread now, thanks for helping, appreciated.

is your Windows 8 32bit or 64bit?
if 32, that would explain part of the reduced RAM capacity as only 4GB (just shy) is addressable on 32bit rigs.

the label does state 8GB, can’t see anything that says it’s a kit.
when you buy stick as a kit, they label them as the combined capacity, not what each stick is, but there should be a label saying 1 of 2 or such, unless it has been removed.

64 bit and i think i bought all 4 as a kit, maybe tgats why it said 8gb then 2gx4. I tested all 4 rams and they are working. Maybe i somehow disabled dual channel mode? could that be the reason why i couldnt put all 4 rams in the slots?

[Lowmemory]

My 2x 8gb rams arrived and tested them, pc sees them as 16gb so those 4x rams i was using are 2gb each. Everything should be good now.

awesome, sounds like everything can be explained away now.
