Hi Everyone,

So i am looking to upgrade my RAM, Currently @8gb , im planning on adding 4gb (more affordable than 8 -happy wife happy life) , through my studies ive found its best to match RAM , so im wondering if i need to find the specific Memory Module thats already installed (came with the pc) , my mobo only has 2 slots for memory with an 8gb module in one.

I know i need a PC3-10600 so im wondering if thats what i need to match, opposed to: make, model, speed?

Any help is appreciated.

So, your current memory is made by ADATA, specs: http://www.adata.com/us/specification/152
It's DDR3, 1600 MHz, CL 11, 1.5 V - those are the important specs you need to look for. The Crucial RAM you listed is 1.35 V, there is very high chance it will not work since your current RAM is 1.5 V.
Anyway, here is almost exactly same RAM as you have: https://www.amazon.com/ADATA-Premier-1600MHz-Modules-AD3U1600W8G11-R/dp/B007UHFW2W

One more thing is, even if your installed RAM is 1600 MHz, it does necessarily mean it runs at that speed. If the OC has not been turned on, it runs at highest non-OC speed, 1333 MHz in this case.

It's always a lottery when adding new stick of ram to existing one(s) - it will work or not. You can maximize your chances of success by getting EXACTLY same ram as you already have (and I mean exactly), but even then you don't get 100% chance.

Mobo docs have this under memory Specifications: DDR3 1066/1333/1600(OC) 2 DDR3 DIMMS (240) 1.5 Ssupport Dual Channel Mode.

I was looking to purchase -Patriot Signature 4gb PC3-10600 (1333 Mhz) DDR3 Desk Top Memory.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this; AMD in particular.
That is why ram vendors will NOT support ram that is not bought in one kit.

What is plan "B" if your new purchase does not work?
Will wife still be happy?

How much do you truly need more than 8gb?
Are you experiencing significant demand page faults?

Might be best to pass on a ram upgrade until you feel you can buy a 2 x 8gb kit that is supported on your motherboard.

So i just got home i ran the scan on Crucial website to find compatible Memory., found:

Crucial 8GB DDR3-1866 UDIMM CT5008696
DDR3 PC3-14900 • CL=13 • Unbuffered
• NON-ECC • DDR3-1866 • 1.35V • 1024Meg x 64

I also opened up my Tower took a peak at what i have currently installed (came with the PC) and this is what i found:

AD3U1600W8G11-B
DDR3 1600(11)8GX16 U-DIMM
10243155

Now im all messed up lol, First the one that the site has as compatible , the last numbers stick out at me "1024Meg x 64"

The one i currently have installed "8GX16" , admittedly i am not sure if this is an issue or not as im still learning all this.

Then i think back to my first post where i listed the Memory Specifications: DDR3 1066/1333/1600(OC) SDRAM (16GB MAX) 2 DDR3 DIMMS (240) 1.5 Support Dual Channel Mode.

So i took the above to mean 1066(low) 1333(high) 1600 (Over Clock), i was going with the 1333 since im not to familiar with OC, come to find out i already have a 1600 installed..

Just when i thought i had an understanding of this i feel lost again lol.:rofl:
