RAM confusion

Motherboard specs say max 128gb but memory choice didn't throwout any red flags when I pressed "proceed"

Is this going to be a problem?

Thanks guys

HI
Nice build, I think your right about the memory issue, do you really need 192GB? Please tell us what your intended use is. I'd be far more concerned about the power supply. You may get system crashes with a 850W, I'd go for a 1000W at least.

Yeah what's this build going to be used for that's an obscene amount of RAM that would be extremely niche?

Secondly I'd want a different cooler, the H100x while great is very very old now and been superseded by newer much better coolers. With the 7950X3D I'd personally want a H115i minimum

Hi thanks for the reply,

I’ll be using it for a combination of gaming and 3d modelling, often with several pieces modelling software open at once so wanted to go with the best specs I can afford. I originally picked a 1000w supply and when I hit “proceed” it recommended the 850w, happy to go back to the 1000w though if it’ll prevent problems

Hey, thanks for getting back to me. Usage is 3d modelling across several pieces of software usually with other things running in the background, and gaming when not modelling. Wanted the best I could afford and that was the highest option available with the choices of motherboard I was given.

I’ll have a look at that other cooler thank you

If the H115i was your minimum choice what would be the ideal option? I’m happy to jump all the way to the H150i LCD XT if it’s worth it?

There's honestly not a whole lot of difference in them the H150i is definitely better but not by a lot. The H115i is very very capable it's just down to what you feel comfortable with

Hard to determine the RAM usage, I do 3D modelling as well but it's mostly data centres, oil & gas plants, pharma, etc and I'd barely touch the sides of 64GB. I just struggle to see where the need for so much RAM would be but hey it's your money

This. Our designers model some huge assemblies in Autodesk 3D and Revit with thousands of parts and "only" 64GB RAM in the workstations. Only use case i can see for that amount of RAM is a host machine running VM's

Yeah I had the federated model for a data centre running which is absolutely massive and that was using around 48GB

That's odd? I've just ordered a similar/slightly less spec ( 12 core Ryzen 9, 4090 (not oc edition), only 1 SSD) and the configurator told me I needed 1000W - which seems about right to me.



I know first hand how annoying an underspecced PSU can be from my last build 5 years ago and for an extra few quid i reckon its worth it, especially at this level. The CPU and GPU alone potentially could draw 740W in transient spikes which doesn't leave much headroom to run ever thing else. My last computer would just keep churning out the BSOD whenever I rendered anything but a better PSU solved all problems. An extra £20 on a 4k build is nothing.

You must be doing some fairly epic scenes to justify 192GB, I've never gone past 32 and even then could have easily optimised models with no loss of quality to reduce this, if I wasn't so lazy. What modelling software are you using?

Im sure I could get away with a lot less ram if I’m honest but I’m self employed and recently just sold an expensive piece of gear, as I understand it IT equipment is tax deductible so I kinda want to use the money I made on something I can write off. I use ZBrush for sculpting models made of several subtools usually at tens of millions of polys each. Luckily ZBrush is very resource light but I often have to jump over to Blender for hard surface modelling or rendering and Blender doesn’t seem nearly as well optimised for resource usage as ZBrush.

Like I say, I’m completely sure I could get away with less but I’m happy to have a system that I can throw as much at as possible without any worries. My original budget was nearly double the cost of this build but decided the threadripper route was going to hinder more than help.

I’ve dropped PCSpecialist an email to see if the ability to choose that amount of memory with that motherboard is an error or not, so hopefully they can shed some light on the situation and I can burn some money.

Oh and I’ve changed power supply to 1600w, and changed the CPU cooler as recommended by the other guy here

Well I mean if the goal is to burn cash I'd be aiming here, the speed of that RAM isn't ideal either Ryzen need the fastest RAM you can throw at it to work at it's best and for the record this is silly and feels silly but this is as good as it gets right now on the config
