Bruno 50 Posted January 29 (edited) 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. Edited January 30 by Bruno 1 Quote Share this post Link to post Share on other sites
subaruwrc 64 Posted January 29 mm donno man. look at my kits. both A1 but different bin. 2 Quote Share this post Link to post Share on other sites
Bruno 50 Posted January 29 (edited) 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.

Bruno 50 Posted January 29 I just got this from Facebook. It confirms my theory.

Remarc 25 Posted January 30 there since capacitors, not resistors,but find is interesting 1 Quote Share this post Link to post Share on other sites
Bruno 50 Posted January 30 (edited) oh, ok. Capacitors, not resistors. thx for info. Edited January 30 by Bruno 1 Quote Share this post Link to post Share on other sites
Johnd0e 15 Posted February 4 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 1 Quote Share this post Link to post Share on other sites
marco.is.not.80 95 Posted March 30 Excuse my ignorance but doesn't Thaiphoon Burner identify which PCB revision the vendor used? Quote Share this post Link to post Share on other sites
buildzoid 20 Posted April 17 Not all vendors program the PCB version into the SPD. I know for a fact that Corsair doesn't IDK about others. 1 Quote Share this post Link to post Share on other sites

Sparks.nl 25 Posted July 18 Thanks, my best kit seems to be A1. Aug 2016 kit (3600 C15). Running 4266 C12-11-11 at just a bit more then 2v. 1 Quote Share this post Link to post Share on other sites

AutisticChris 98 Posted July 19 @Sparks.nl Is the issue with the stick on the IC or the PCB? Quote Share this post Link to post Share on other sites
Sparks.nl 25 Posted July 19 (edited) 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+ Edited July 19 by Sparks.nl 2 Quote Share this post Link to post Share on other sites
