System - Bought a year and a half ago.
Asus Maximus V Formula - (2800(O.C.)/2666(O.C.)/2600(O.C.)/2400(O.C.)/2200(O.C.)/2133(O.C.)/1866(O.C.)/1600/1333/1066 MHz Non-ECC, Un-buffered Memory ) (Whatever all that means)
i5-3570k - Overclocked from 3.4 to 4.4ghz
Corsair Memory Vengeance Jet Black Low Profile 8GB DDR3 1600 MHz CAS 9 ( I think)
EVGA GTX 670
So players have been reporting significant performance increases on Arma3 on higher RAM speeds, I want in.
I assume I can go into BIOS and just press something to change my ram speed up to 2133? But will this kill my ram or should it be fine?
EDIT: Checked BIOS and it says my RAM FREQUENCY is 1333. Does that mean that this is default for this ram or that the BIOS just sets it to that whatever. I upped it to 1600 for the timebeing anyhow.
The bios will set it to the default for that ram
Well, you will at least most definitely be able to set it to 1,6GHz without any problems.
[QUOTE=djjkxbox360;43945162]The bios will set it to the default for that ram[/QUOTE]
DDR3 memory modules over 1333 MHz generally don't have their native timings stored in the SPD ROM on the memory stick and will run at a lower speed until you manually set the RAM to run at native speeds. The exception are the few memory sticks that have those XMPP profiles and the motherboards that actually support reading that extended data.
The reason that memory modules automatically run at a lower speed is because not all motherboards tolerate faster memory speeds, and since modern CPUs have the memory controller integrated into the CPU, things get even less tolerant of memory clock speeds and especially voltages.
OP, the fastest memory your CPU officially supports is DDR3-1600. Intel memory controllers are very unforgiving of overclocking and especially running memory at higher voltages. If you do something wrong, you may end up damaging or destroying your CPU.
I would not recommend trying to overclock your memory, and I really doubt you'd get an additional 533 MHz out of your modules without them not working properly or damaging your CPU. And realistically, I don't think you're going to get more than a couple of extra frames at best even if it worked. You said that you went from 1333 to 1600, but did you notice any appreciable gains? If you didn't, going from 1600 to 2133 isn't going to be any different.
And lastly, were the gamers that said the RAM speed increase on AMD APUs? because they're extremely sensitive to memory speed (since the GPU uses system RAM.)

This. APU's are really the only thing that benefit from higher clocked RAM. Granted, I have mine clocked from 1333 to 1600, but that's just for the hell of it.

Thanks for the long post! Appreciated!
That's disappointing that you dont think my CPU can handle it. I was under the impression the 3570k was very good all round (back before the current gen). I wont go over 1600 if thats the case so thanks for the heads up.
I actually noticed some decent gains in FPS! Definitely a few frames up on before!
The first to suggest the higher speed RAM was someone on a 2600k & 7970s in crossfire.
There are now a few people doing benchmarks, and quite a few people getting extra frames where they havnt been able to trying different methods.

If you have a dedicated GFX card there will absolutely no noticable performance increase.

I have already noticed noticeable performance increase.

And what's that?

The CPU is fine, and is fine for overclocking the core clock. There are just some things on it (like the memory controller) that are less forgiving to abuse than other parts of the CPU (like the cores.)
