I think what would help for those of us unfamiliar with this board is a photo of the bottom to see if there are traces leading to nowhere. I have one of the old PC Chips M919 boards with the fake SMD cache on it and a slot for a real Cache Module that looks kind of like a COAST slot but is not - the fake SMD cache is obviously fake to anyone like me who makes circuit boards - you can see the traces just loop around.

The only thing that looks fake to me, maybe, is the chips in the Cache sockets, and that's because I've never seen that brand before. Could just be some oddball chinese knockoff brand making Sub-Par chips - you see that a lot when it comes to making electronic stuff using cheap chinese parts off e-bay - like me building guitar pedals - it might be functional, just might be those chips are not performing their best.

Good point. Traces seem legit, but I'm certainly no expert 😀

Actually the M919 is the only case I know of fake cache with traces leading to nowhere. If you're really not sure if the mobo supports cache, take a multimeter and check if there is a voltage between where the VCC and GND pins are supposed to be. If there's one, then making fake wires with some getting power would be very strange isn't it ?

If you don't have a desoldering iron, you can simply cut the chips off and then remove each pin using a soldering iron on one side and a pair of pliers on the other side.

I have now two non PCChips boards that have/had fake cache. I added real cache on one of those and it worked without any problems, so did I with my PCChips m915. The last one has a UMC chipset and is quite fast so I will add cache to it as well.
