DDR3 performance

[Mick Naughty]

About to build a second rig, need ram. I was talking to a computer friend and he mentioned that having higher cas ram could cause the CPU to try harder or slow it down pretty much. I was having a lot of high CPU usage in games. 

 

This is is what I have

in my Asus Maximus 6 formula. 

I only game on it. Will be starting to edit videos soon. Preferably on both rigs. Just wonder if there's any benefit to be had at all.

Not really any difference to be noted. Just get like 16GBs and you'd be fine

It won't matter in gaming scenarios or really any consumer scenarios for that matter, even higher ram speeds most of the time are pointless (except in fallout 4 and probably the skyrim remaster)

CAS latency can make a difference, but practically never a difference you'd notice.

 

And the latency is quoted in clock cycles, so you have to divide by the memory clocks to get a comparable number. CAS 11 on that kit, for example, is faster than CAS 9 on a DDR3-1600 kit.

anything higher than 4GB and you should have no problems.

 

If he's talking about the ram's clock speeds slowing down the computer he's full of shit

That's a load of nonsense. CAS latency won't have a big impact. Neither will RAM speed (Unless you're using iGPU).

Perfect. Wasn't looking forward to swapping these ek blocks over and some how getting heat spreaders for my old ram. So 16 gigs should be good for editing 5-8 gig 1080 videos? 

Gonna be on an 3770k at 4.5 on a saber tooth z77 and Titan black, hopefully all on water if I can decide on a case.

Sure. 16GB RAM is great,

CAS speed and frequency will only help if you have a cpu at 100% load constantly, and cannot upgrade the cpu. If you go from 1333 to 2400 you might see a 1-2fps increase, and CAS latency really is only useful for things like Cinebench, and other benchmarks.

Well depending on the map in the game my 3770k would be pegged at 100. I had to turn down the graphics to in order to play. My other game it would hover at 80-90%

Turned virtualization on and it would stabilize the CPU quite a bit. Stepped up to a 4790k. Seems to be a bit better.
