Dual Xeon 1240v3 how much ram can i have?

It says that one xeon 1240v3 can handle 32gb maximum ram.
How about, if i have a dual xeon in my system and 64gb ram,
each cpu can use 32gb or is the 32gb the maximum?

Probably the first, but just checking ofcourse.

P.S
2. an i7 3820 or dual xeon 1240v3? Overclocking aside(xeon can't), i strictly work
with autocad, adobe, 3dsmax and cinema4d. Editing and rendering is the only
importance. Is a dual xeon the smarter choice raw performance wise,also considering it would have 8cores/16threads vs 6cores/12threads?

teun3sixty,

The Xeon E3- 1240 v3 may be only used in a single CPU configuration and as you know, an E3 will support a maximum of 32GB of RAM. To use dual Xeons, you must use the E5-2XXX series. Also, the E5 series has twice the memory bandwidth as E3 so there are dual Xeon motherboards with the Intel C602 chipset that support 512GB of RAM!

Rendering is one of the few application that can use as many cores / threads as possible so if you can have a system with dual Xeon 4, 6, or 8 core so as to have 16, 24, or 32 threads, that will be the fastest. Xeons used with ECC error-correcting RAM will not have rendering artifacts and will have more accurate shadows and color gradients- that do not appear as rainbows.

I use some of the same applications and tasks that you list. As dual Xeon systems are expensive, - a single E5-2687W 8-core CPU costs $1,900 in the US (and many of the E5-2XXX are $1,400 or more) one tactic that has worked for me has been to buy a used Dell Precision with dual Xeons to run renderings. When I changed from a 1-CPU to 2 CPU system and could assign 12 or more threads to the renderings it was much faster.

My system is old fashioned now DDR2 RAM) so I would suggest a Precision T7500 with 2- Xeon x5680 6-cores @ 3.33GHz for 12 cores / 24 threads. A dual CPU T7500 supports 192GB of DDR3 ECC RAM 1333 and these have very, very good quality construction.

If you must have a new system, consider a system with an E5-1650 six core @ 3.2 / 3.8 GHz a motherboard with the C602 chipset and ECC 1600 RAM such as an HP z420. The E5-1650 is the best value for a fast Xeon- only about $600 and No. 12 fastest CPU on Passmark CPU benchmarks- E5-2687W is No, 2 but costs more than 3X as much. But, if rendering is very important in your work, I would advise against a quad core Xeon E3.

Cheers,

Yes yes yes, thank you for the informative answer and invested time. I have a very big goal, I am a philosopher and asked the questions why considering what is life, where does it come from and where does it go.

I currently have a 3630qm, laptops have become powerful i might add, but in order to portray my vision as close to what I want it to look like, I need dual Xeons. I was once up to date with specs but as this industry evolves on a monthly basis keeping up with it is a full time job.

I am now specialized in film editing, 3d modeling, animations and more regarding rendering.
When the time comes for me to order this computer, I will keep an eye out for you and
if you have time, your advice would be very appreciated dear sir.

Dear TM,

You are very welcome at any time. With 3D modeling and animation, a laptop can be difficult as one needs to tun several programs simultaneously and also see very small details. A large monitor and a powerful system is much less frustrating. The greatest single improvement to my work method I've made was changing from a 22" to a 27" monitor.

To have the serenity, take the time, and have the motivation and method to consider the expansiveness of life is too rare today. A great and quiet ambition.

I like very much the idea that consciousness was created by Nature so that Nature may have some appreciation of itself.

Best luck and best wishes,

BambiBoom
