32GB 4000mhz vs 64GB 3200mhz RAM

Building a new PC mainly for rendering and I'm undecided on the RAM setup I should go with.

Specs:

Ryzen 9 3900XT

MSI MPG X570 motherboard

RTX 3090 24GB GPU

I have the option of 32GB 4000mhz or 64MB of 3200mhz and I was wondering what will give me the most benefit in Daz. My main bugbear at the moment is character loading time as this is stretching into 10+ minutes on my old system.

    64GB is always better than 32GB smiley

    I very much doubt that more RAM will help with load times, that's down to all the links that have to be established when there are a lot of morphs/character sets installed (many with hidden corrective morphs into the bargain). 64GB may well be useful, but only under certain circumstances (feeding two, or more, high RAM GPUs for example, or handling scenes with a lot of content and then rendering when it drops back to CPU).

    Since you are buying a GPU with 24GB of VRAM I'd go for the 64GB system RAM as a fallback.

    And are you sure you don't want to wait for the 4000 series of AMD Ryzen 9 CPUs to release last quarter of 2020? The difference will be noticable.

    I keep strict control over what is enabled and allowed to run on my Win7 system (ie. minimal background operations), when I updated the GPU to RTX2070 super, I updated the memory as well from 32GB to 64GB.

    The increase in memory, doesn't help with load times, but it did eliminate the sluggishness when doing other things while DS is rendering, now I don't have to wait for 2 minutes for the background program to open and refresh it's interface anymore.

    The load times can be improved by fixing/removing the products that cause warnings in the log and by reducing the number of installed "characters" and morphs for the used base figure.

    Ryzens run faster with faster memory, so I would go with the faster 32 gigs.

    I'm not sure either are worth the extra cost.  Your bottleneck will be GPU @ 24GB.  32 should be enough.  The difference of 4000 RAM over 3200 you almost certainly won't notice either.

    Check the motherboard manual on the RAM and also do some research as well as to speed and bottle necks

    This your board?

    Specs say it supports a max of 128GB.

    I went with the 64Gb in the end. Saved £50 and I can always upgrade when the 4000mhz comes down in price.

    Cheers all. New PC is 2 weeks away, now I just need Daz to release the next beta that works with Ampere.

    If it isn't present, it can't be used.

    I wouldn't bother, unless perhaps you're an avid gamer and the speed increase will really give you that much more performance.

    I thiink your video card will have you covered with Iray rendering with its 10000 Cuda Cores. The ram is only helpful with when you're working within Daz or any other program and its responsiveness to your actions. Having 64 over 32 wouldn't be too noticeable in the videos I researched. Save the money.
