Hello I have a lovely new PC i built myself and it works amazingly however some games liek wildlands does say it needs more memory and because i thought well why not i can fit it and i will not have to upgrade again for a long time anyway.

So essientally i have a Asus Prime motherboard and rocking with a R5 1600 OC to 3.8GHz

i have already 8 GB of Corsair Vengeance memory at 3000MHz

and decided to buy the exact same brand and exact same package. I enter them into my PC and nothing happens
I reseat all 4 again nothing happens I reseat just 3 incase one is broken. It loads! to a Repair screen?



So my question is what can i do to actually have all 16 GB of memory working.

~Right now i recieved £80 of items that i cant use it would be great if i could actually use these.

Currently have it running with just 8GB atm

Thanks!



 
run a memory diagnostic with all chips installed. If it throws a bunch of errors then you likely got a bad stick. RMA the new stuff. I'm surprised you were short on memory at 8G. that should be more than sufficient in most applications.
 
Ok even buying the exact same make and model is not guaranteed to work, this is why RAM is sold as matched kits.

Take 1 stick and try it in all 4 slots. If the system boots each time you know all motherboard slots are working. Then try each stick individually and see if the system boots. Then let us know how you got on.

RAM timings for each additional module or a new kit is different, and is highly likely to end up not working properly and not even letting the system POST, which is why, just to make sure it works at once, RAM should ALWAYS be bought in one single memory kit. It's highly unlikely for three RAM sticks to work at a time. To try, you must install the old kit into a single channel and the new kit in a different channel. Or you can try slots A1 B1 for old kit, A2 B2 for new kit.

I've had a seriously annoying experience trying to run RAMs from different kits but the exact same serial number and specs at the same time. At times, even after a simple power cut and an instant shutdown, it all would just suddenly stop working and I'd spend hours switching RAM slots here and there.

I read an article written by tomshardware member named "meanmachine", explaining in detail why this happens. I can't currently find it's link, will update ASAP.

Good luck.
