RAM for Threadrriper....3!

[Kumicho]

Hi folks

 

This is my first post, so, hello everyone.

 

Im 3D artist an Im planning my next build, hope Computex at this month bring some light.

 

I would to build a machine with a Threadripper 3 and 128Gb of RAM.

 

Never had a Zen. Im actually on Coffe Lake. But I read a lot about how to deal with Ryzen architecture and RAM.

 

Unfortunetly I will have to deal with 8 sticks of RAM, all that chiplet stuff, pretty intense loads and some games/engines eventually. I usually build expensive PC that I use for 4/5 years with minimal changes (only GPU). For that and work-trust reasons Im searching quality components.

 

I heard about Samsung quit B-die production and I ve started to seaking for a good RAM now we had reasonable prices.

 

Option 1
From what I could find in stock in my country Im interested in one of these two modules:

 

• G.Skill Trident Z RGB 16GB  3200 Mhz (PC4-25600) CL14 LED RGB
• G.Skill Trident Z Red/Grey 16GB 3200 Mhz (PC4-25600) CL15

 

With 128Gb kit, the diference in price is almost 300$, so, I have to make a choice.

 

I ve seen the "ZEN" G.Skill modules, but I trust Zen 2 could handle well these speed and latencies. Is it worth CL14 for 300$ more? Dont think so, but...Or maybe I should go for more Mhz?

 

Option 2

 

Any other good recomendation in that range of price, quality and in stock?

 

Option 3

 

Try to convince me  of wait until AMD show something oficial.

 

Thank you pals.

Threadripper 3

TR3 was actually taken out from the roadmap.

Well, I actually read about that.

 

Usually AMD, they didit with TW2, realease the workstation lineup a few months later. In case of TW3 never happen, I go for Ryzen 9 or similar. But that does not the point of the post.

 

I will not rush this build, but the RAM prices and Samsung B-die announcements...

Be careful with 128gb ram. With current threadripper I can't imagine 3200mhz cl14 is going to happen with 128gb.

 

I've just took a risk similar to what you're taking, just to a much lesser extent. I've gone and bought 2x16gb 3466mhz (Had to because it was one of the few well priced corsair samsung b die kits remaining on the market) for my zen2 build. It's a much safer gamble than what you're trying to do.

 

Zen2 seems to go up to 4000mhz according to the new biostar x570 leak. But that doesn't mean 4000mhz with 128gb ram. It's more aimed at 16gb ram, maybe 32gb max. Whether you'll get 3200 stable on 128gb on zen2 is up in the air at the moment.

 

I'd wait a bit longer for more information on memory speeds, and of course more importantly..whether Zen2 threadripper is even coming out.

just get identical kits of 16GB sticks at 3000mhz. no need to buy them all in a single pack.

Thanks for the coment, I hope your build works well.

 

The problem here is the end of B-die production, announcement made by Samsung yesterday.

 

I fear that there will be shortages and prices will go up.

 

I would never take those risk in other situation.

 

Understand your point, but, is there any other options? I think to go for good chips (not too fancy speeds) Its the most safety bet.

I ve saw his videos.

 

Unfortunately he focus too much on ECC memory, but I need to review his videos again. Thanks

B-die is more or less irrelevant because the memmory controller is nolonger as bad as it was in first gen.

This could help you when searching for B Die kits. There's some 3000mhz cl14 128gb kits on there which would be safer options and probably cheaper. Click 'All Kits' and then click 128.

It's unlikely you're gonna get the memory working at 3200 Mhz with all the memory slots populated.

 

You have 16 GB memory sticks which are most likely gonna be of DS type, and you have 8 memory slots... maximum frequency officially supported is quite lower: https://en.wikichip.org/wiki/amd/ryzen_threadripper/1950x#Memory_controller

While you may get lucky and get them to run at 3200 Mhz... I don't think you'd benefit much in real world... better save money or shuffle the budget to another area.

 

Threadripper 3 series (based on Ryzen 3xxx dies) doesn't exist... if it's gonna be released, it will probably be next year or in winter of this year.  August 2019 is a date thrown around.

Good point.

 

However I think I need top products (not expensive luxury) for my workstations.

 

But I didnt make that relation between controller improvements and old B-die tips for Zen.

just get regular memmory. its not like there is an actual difference between memory. 

 

at best get cl15 memmory or cl14.

Why Threadripper rather than Intel HEDT?

Two 4x16GB kits would be reasonably safe. Buying smaller kits poses a small risk of not achieving quad channel memory operation.

im guessing rule 2. 

 

also why would you want Intel HEDT over any other offering?

Intel HEDT platform is far more expensive than equal AMD, and of course cores. Rendering on CPU is core demanding, you can see Pudgets articles or CgDirectorr about this. Is there any 32-core Intel procesor at same price that 2990W?

 

Well, you have to move to Xeon in this scenario, and again, more overprice, plus deal with Xeon family, dual socket...

 

Sorry bro. This decision was taken, its all about cost-benefit dilemma and making it simple.

 

Whenk I said "kit", I mean buy 16 sticks to make 128

Rule 2?

 

I'm not suggesting one would. Each platform has its strengths. Since the OP did not say much beyond the suggestion that the system would be used for some aspect of 3D work I'd hope to get an understanding of why Threadripper was

Understand, I'm not trying to argue Intel over AMD, simply looking for the best solution. HEDT is not necessarily much more expensive than Threadripper. It really comes down to the actual workflow.

 

From this response I take it that the rendering engine is not able to use gpu resources and that reducing rendering times is the paramount concern? What software is being used?

 

CL14 will make a difference over CL15 in long rendering jobs. The important thing with memory though is to consult the motherboard memory QVL. Some memory manufacturers also have QVL for motherboards.

 

My comment on memory kits was aimed at another posters suggestion that one buy less than an 8x16GB kit.

I really appreciate your point of view on this.

 

On freelance I usually work with Maya as DCC and Arnold/Vray on rendering, when is a team-work...usually the pipeline and deadlines impose their needs. From Redshift to Lumion.

 

Love the speed and look of some GPU renders, but nowadays I dont want to go allin in one solution. Sometimes the engine not support certain features in GPU or whatever. Im planning a balanced build, with Threadripper and RTX2080, and probably update GPU in 1 year or so.

 

I will take into consideration your contribution on latencies. Thanks
