Rogue Leader :
What that means is, while ASUS makes good board you are not limited to those in terms of whether DDR3 will "work". There are NO Skylake boards that are "ok" to run normal DDR3. Intel recommends AGAINST using DDR3 in any form except DDR3L, despite how the guidelines may appear on that board. We have not yet seen a failure happen, but there is a reason they recommend against it.
My suggestion, spend a little more money and buy a DDR4 board and ram, don't use your DDR3 ram.
Now I think I understand what you said, those boards are 1151 socket,is that the problem? should I be looking for another socket? say like 1150? the examples of models are in no shape or form a definitve pre selected thing,I just look'em up and saw it would have fitted my needs.
My plan and current setup (just to being 100% clear) is :
an I3-3220 processor
a gtx 1050 gpu
and 4gb (this week will be 8) of ddr3 memory
Now what I want and plan in the future is
-to buy another motherboard, so I can buy an i5 processor (not quite sure what gen to get (that might be part of the problem) )
-But still having support of the mobo, and the processor of those 8 gb of ddr3
im NOT buying ddr4
