A1 or A2 PCB - easy recognition


Bruno

Recommended Posts

Hi guys,

 

I discovered we can easily know which PCB a memory has, just by looking at the module. No need to look under the heat sink.

My finding is this:

A1 has a resistor capacitor above the slot cut and other resistors near it.

A2 has only one resistor capacitor, a bit on the left from the slot cut and he is all alone there.

The image shows A1 on the left and A2 on the right.

My teammate GGI78 also checked his G.SKill kits and confirmed my idea.

 

Important: you have to look on the side with the label, where the chips are.

 

Please check your kits and confirm.

Exactly. The Resistor capacitor is right above the slot cut. And there are some other resistors capacitors near it, even if only 1 or 2. On A2, the resistor capacitor is a bit on the left from the slot cut (not above it), and there are no other resistors capacitors until the ones under the chips.

Just a PSA, For those who think they can just look at retail photos to see if the sticks they are buying are a1 or a2 DO NOT trust it. Some retail photos are not what actually ships to the customer. So again, do not base your purchase off of retail photos, best thing you can do is google the model number of sticks you plan to buy and find customer photos of the kit to see where the capacitors are. 

 

Also, i cant confirm or deny this capacitor theory, but my a1 sticks definetly have the capacitor above the notch and my 1 kit of a2 do not. So it would appear to be a plausible theory.

JohnDoe, wow great to see you here ! Just yesterday I found a folder on usb drive about similar situation with your name on it. Good times

The defective one? My m ocf memory slot 1 had problems before, now it finally went up in smoke and took the dimm with it. 

I don’t know what is causing it, but with this dimm in any slot I don’t get a post. It should do 4200 c12-11+

could some one help me source a capacitor for my bdie kit didnt notice it was broken off when i bought this kit off ebay until i decided to take my heat spreaders off

i get a resistance of 40ohms measured one way and 150 ohms measured the other way but i dont got a cap tester sooo   F for respects to this kit
