No it isn't feasible. The ram on the XBox One and PS4 are ptp connections. If you examined the pcb of the XBox One, you'd see that the board lengths of the address and data bus traces are pretty much identical (ddr3 cannot learn to sync, gddr5 can). You are running the bus at >1GHz so there is very little room for detours for any trace. Solder in another group of rams, somewhere and immediately you see the problem, the trace lengths no longer align (apart from the fact you have a 256 bit bus, so you need some pretty fancy idea for 4GByte more). Let's not forget that the memory interface is now loaded with two chips. If you didn't design the controller for multiple ram chips right from the start, your APU is just gonna blow sooner or later. It is interesting that this nonsense rumour already lasted for 20+ page. This rubbish probably comes from the same "source" that decreed "2 APUs 12G Ram 5TFlops gpu" some months ago. That turned out right, didn't it? |
How about you use your knowledge to educate those yapping on about a change like this causing RROD because you know as well as I do that had very little to do with design changes on the 360. It also had nothing to do with the cooling either...
