Does Faster RAM Really Improve Render Times?

[Guest]

Just want to know if it's true.

If you have like 100+ mods on Ender Scrolls or MC than yeh it would. Not sure if it would with like a FPS or RTS.

Slightly, it let's the program access data quicker so it can be rendered, it's marginal though.

not worth the money, getting more capacity is better.

Video encoding (you haven't specified what type of rendering) can actually be improved fairly significantly for minimal outlay with RAM. Its a very bandwidth intense activity and hence benefits from quite a lot of bandwidth. But its not like your going to see 2x performance for 2x faster RAM, its more like maximum 10%.

Only if your CPU can handle it. If your CPU isn't bottlenecking the RAM, it helps tons (where CAS Latency matters, otherwise higher frequency = better). At least this is how I've understood RAM bandwidth so far, apologies if this is incorrect. Anyway, here's an example of what I mean.

3000Mhz CL14 or something vs someodd 2400Mhz CL11 with 4k raw video processing on a 3930k = CPU bottleneck, instantly in favor of 3000Mhz despite looser CAS timings AKA higher latency. I'm not really sure what the threshold would be in terms of RAM, but I don't know why they'd make 3000Mhz RAM if you were only able to use, say, 85% of its bandwidth.

Opposite scenario:

2400Mhz/even 2133mhz CL9 (these exist, I believe A-DATA sells them) vs 3000Mhz CL14 with a 220MB Blender file on a 3930k = Not really any CPU bottleneck, tighter timings on RAM + moderate bandwidth would be superior.

I'm quite confident I'm not wrong but if I am, don't sue me ^^; I'm not a RAM expert just yet. Either way, these examples shouldn't be considered 100% accurate. I only put them there to illustrate my point.

Sorry to high jack the topic, but I have a specific question that is in direct link to this thread.

I have 8 gig of [ RipjawsX ] F3-17600CL7D-4GBXHD (DDR3-2200) running at 8-8-8-16.

Since their native specs are 7-10-10-28-2N should I try to tighten them to CL 7 (probably have to lower their speed 1 notch) or should I keep them like they are?

It's more toward video editing performance.

CPU is a I7-2600K @ 4.7 Ghz
