Total that got cut of there was £3,309. Which to be fair given what it allows me to do now will mean it should pay for itself within a couple of years worst case.

Hey all, thanks for all your replies to my previous post about the beefy machine for test renders, i am delighted to say i have gone ahead and ordered the machine after switching the gpu to a 4080 super, and getting a slighty better power supply.

I have also decided to go ahead and double the RAM to 192GB while they are still builing it. But i am getting concerned about cold boots and memory training.

How often does memory training happen? Is it every cold boot? Every manual reset?

The machine will be crashing alot, its just the nature of pushing them hard, and i dont want to be stuck waiting with that horrible feeling of if it will ever even boot at all, the next time i push the render quality a little too high in 3DSMax.

Would greatly appreciate some feedback on this from someone with experience of machines that have alot of RAM.

    Large amounts of RAM should not significantly impact boot times unless you have a bios / efi that is doing a full memory check every boot like old computers used to do 30-40 years ago.

    Memory Training? I assume is when the mobo tries overclock settings until it finds something that works. For a renderfarm, that’s not good.

    In the EFI you can choose XMP profile or DOCP profile for your RAM, but beware that just because the RAM supports that speed, the mobo and CPU might not. Example, I have DDR4-4600 RAM that I can only run at 3000 speeds because my CPU can’t handle 4600 speeds.

    It will take some tweaking and testing and benchmarking to find the optimal setting that doesn’t crash the system during a render.

      Thanks this is all i needed to hear, my PC knowledge is kinda out of date sadly, i was a PC builder once many many years ago, just when they first became modular.

      For my purposes on this machine then, i will assume the shop will just check all of the XMP stuff for me and make sure its setup correctly. I have already told them it will be for rendering, so i will assume they know what i need.

      Thanks for answering!
