If I increase my RAM will my laptop render iray a lot faster?

Here are my specs:
Intel(R) Core(TM) i5-8265U CPU @ 1.60GHs 1.80GHs
Ram 8.0GB (7.89GB Usable)
64-bit operating system, x64 based processor
Is there anything I could do to this computer so it would render typical scenes(one frame) in less than 5 minutes? Increase RAM or whatever? If not, do you have a suggestion as to the cheapest computer that would render scenes in under 5 minutes (on average)?
*A typical scene would include an environment optimized for Iray and two characters.

More RAM is generally better, but limits will depend on your motherboard. If you are wanting faster Iray renders an nVidia graphics card would assist, but the ability to use one will, again, be dictated by your motherboard and what you currently have in place. You may have an issue with power requiremnets if you add a graphics card to the laptop; you don't mention one so I assuem that the motherboard has an 'on-board' graphics chipset. RAM tends to be used in the build-up orcess of a render and will peak at a high (relatively speaking) level, and can then drop. The problem comes when that peak exceeds physical RAM and swapping to disk starts happening. I'd check how your RAM is being used with one of your typical renders to see if more RAM would be useful.
Thanks! I just did a render while my brother monitored disk usage and he said that I am running out of RAM. I will try to add RAM to my computer or get a new computer. Cheers!
If all you're doing with it is Daz then adding more RAM is an expense you can skip. You need an Nvidia GPU. You are never going to get that laptop to render a scene in 5 minutes no matter how much RAM you add.
Darn. Yeah, I've started looking into getting a new desktop or something. Or use a daz render cloud.
Even with a high end desktop, many scenes will take longer than 5 minutes to render if you want a quality render
The main issue with fast rendering in daz studio is that the denoiser doesn't work properly. Because it doesn't use the albedo and displacement buffers. So it can't preserve details and you'll get a blur effect on your renders. Using an external denoiser can't fix the issue for the same reason.
I'd expect this to be fixed soon. Meanwhile using 4.12 with a rtx 2070 or above is the best you can do as for speed.
Oh. I might just stick with 3Delight then, which is something I am fine with. My computer renders 3Delight images in just a couple minutes. Unless I can find someone with a supercomputer who I can pay to render my scenes.
I think you're talking about ProRenderer. It's denoiser has a color and color, albedo, displacement options. Iray doesn't.
A denoiser that has been trained correctly will preserve details, and the longer you let the render run with the denoiser going the crisper the image will get.
A long run render will always be right, it doesn't need a denoiser. The whole point to using a denoiser is to get a nice render with few iterations, that's needed for animation. So a denoiser that doesn't use albedo and displacement but only relies on long run trained "guessing" for details doesn't really make sense.
I have literally no idea what you're talking about. I can let a render run to completion, 30 or 45 minutes and 2500 or more iterations, or let it run to 500 or 750 iterations with the denoiser and get a completed image either way. I've even run them through image comparison programs and the images are so close to identical it took me a while to find a pixel different between the two.
An AI denoiser isn't guessing. It's had tens of thousands or millions of partially converged and full converged images thrown at it. It creates many different algorithms to get from one to the other, the first generation are essentially random, and as the thing keeps running it discardst the worst and refines the best. The results go from laughable to very very good very fast. About a quarter of the racks in my datacenter are either training AI or running trained ones in production. At the prices we charge businesses wouldn't be doing it if it was just "guessing."
Ok here's a simple proof of concept. Below there's the same cube with basic diffuse and bump maps rendered at 16x iterations with the denoiser on. First iray then cycles. You can see that cycles preserves the details while iray doesn't. That's because iray simply can't without the albedo and displacement buffers. You can do similar tests yourself to better understand the issue.
Tested with daz studio 4.12.0.86 vs blender 2.8.
Sarcasm is lost on some people. You don't understand the topic. I'm not going to keep banging my head against that.
My purpose was to explain why the iray denoiser is not effective, and thus why other engines using a better denoiser are faster. I didn't mean to be impolite in any way.
