I believe the spec starts at 800 and goes up in 266 increments (800, 1066, 1333, 1600, 1866, 2133, 2400, etc).[/QUOTE]

I stand corrected....800 it is.


Same question though. Is it possible that could be capable of 7.68Ms times for 2048K FFT.

If so at what RAM speed do I no longer get improvements...is the MB or CPU, etc become the bottleneck.

Might be 1333 rather than 800; tiny "1" in close proximity to "3" looks like an "8".

Well, a i7-6700 probably takes DDR4. The lowest common speed for DDR4 is 2133 MHz.

Get a stick of DDR4-2133 that matches the size of one of the existing sticks.

Assuming the motherboard does. It is unlikely that you would be able to replace ddr3 with ddr4. The sockets at least are different. There may be motherboards that support both.

Expert opinion?
 

2X8GB DDR3 - 1866 and 2400 both under $100 ... what's that catch?

Yeah I noticed bit it didn't seem like a lot.
Does that CAS difference make up for the speed difference?
In other words which is likely to perform better for GIMPS?

[i]If your board can actually support[/i] DDR3-2400 then you're probably better with CAS11@2400 than CAS10@1866, but whether it will make any appreciable difference I can't say. I'm sure others can.

Can anyone easily tell me if this will support 2400 DDR3?

Acer Aspire T3-710 V:1.1

This machine? [url]http://www.acer.com/ac/en/SG/content/model/DT.B1HSG.001[/url]

It takes DDR3[b]L[/b]-1600 at 1.35V.

The memory at both those links won't work. Try this:

[QUOTE=petrw1;440798]Acer Aspire[/QUOTE]As a generalization: Probably not. "Brand name" systems tend to be equipped with parts that are just sufficient to run at their specified settings and no more. Greater abilities mean greater cost, and Acer's not going to pay for 2400MHz RAM support when they're only planning on putting 1333 (or whatever stock is) in there. If you didn't pick the motherboard and build the system yourself (or have your friend/store building it for you) then I wouldn't expect anything above 1600 (if that) to be supported on any brand-name system.
