Please Help !! - Dell Precision T7610 - Very Poor Rendering Performance.....

[amar nikam]

Hi,
2 month back ,We purchased a new Dell Precision T7610 computer with Microsoft Windows 7 for 3d Modeling , rendering and After effect work .
when i started rendering , i found that Dell is not performing as we were expecting ..
this system took almost 8 to 15 min to render one image ....
We are expecting much more faster result . we have tried to same file on i5 system(i5, 8 GB ram , 500 GB HDD, 1 GB Nvida Qudro 6000) which also taking the same amount of time that is 8 min.


For better Understanding i am giving you 3ds max file Details .
we are using Autodesk 3ds max 2015

3ds max file details:
Size : 20.2 MB
Poly Count : 70,383
Rendering Engine : Mental Ray
Material : MR
Lights : 3 Photometric Lights , Shadow : Ray traced , Samples 128

Mental ray settings ( I am using standard mental ray settings ) 🙁
Output size: 1280 x 720
FG : Low
Diffuse Bounce : 2
GI : Off
Sampling Quality : Min : 1 , Max : 16



System configuration :
Dell Precision T7610 1300W Chassis
Dual Intel Xeon Processor E5-2637 v2 (Four Core HT, 3.5GHz Turbo, 15 MB),Dell Fixed Precision

64GB (8x8GB) 1866MHz DDR3 ECC RDIMM
512GB 2.5inch SATA Solid State Drive
Intergrated LSI 2308 6Gb/s SATA/SAS Controller - SW RAID 0,1,10

Please help .how to solve this problem .

That system should be quite a bit faster than the i5 system, did you try to work with Autodesk or Dell? I don't see anything in the system that would be a bottleneck, lots of RAM, SSD, Quadro.

hi, thanks very much for Solution ..................
But the system performance is very poor ... Is there any way to test system's performance? ... because Dell person (India region) did online system diagnostic and said system is OK even Autodesk people said try with dell our software is working fine
This system is quite expensive ......i don't understand what is the problem ..will my motherboard support this graphics card ?? or 3ds max 's problem ? or missing any drivers ?
while rendering with 3ds max ,system become very slow even i cant open windows explorer ............
please help us ....

You can check for updated drivers from Dell, but I don't see how the new system can run at the same speed as the i5. You have a faster video card to help render, a faster CPU and a faster hard drive. Are you rendering on the SSD? If not, use that and see if that helps.

To get a raw performance score, you can install the PassMark performance test, it's free to run for a week or a month or something, and will give you a component by component speed result.

please test both dualcpu rig & i5 with cinebench r15, as we shall measure the rendering performance to someextent. i dont think passmark can give a better rendering mark than CB. also please check with rendering bucket size. lot of articles there about bucket size as they can influence rendering speed.

amar nikam,

The specification of the Precision T7610- dual, fast quad core Xeons, and especially a Quadro K6000- a GPU that is among the fastest workstation cards in the World- fantastic for super-complex 3D modeling, 64GB RAM, a very high quality, high performance RAID controller, and so on- everything seems to have a perfect specification for 3D modeling and ray-tracing rendering- excellent and difficult to improve.

As others have mentioned, that an i5 system can render as quickly seems impossible. The i5's are not hyperthreading and therefore present the same number of threads as cores to the rendering engine- that is four- to the 8 cores /16 threads of the E5-2637 v2's in the T7610. The Quadro 6000 too has 6GB memory and a excellent bandwidth- the finest workstation card of it's day and used to model and render airliners, but the K6000 is another league too.

If I might make a suggestion, if only to eliminate some possibilities:

1. Download, install, and run Passmark Performance Test (30-day free trial), upload and record the results.

2. In Passmark, go to "Manage Baselines" > "Advanced Search" and under "Other" enter "Precision T7610", and then sort each parameter- CPU, 2D, 3D, Memory, Disk to compare to other T7610's. Then, do a search by each other component- especially CPU only, K6000 only, LSI 2308 only search, and etc. to check that these are within range of other users' results. For example: one T7610 with a K6000 score 781 in 2D and 8288 in 3D while another scored 631 and 7734, so the expectation would be that your system should fall within that range. There are five systems with dual E5-2637 v2 CPU's and the CPU scores range from 16784 to 15777. One is a T7610 with a Quadro K5000= 16138. Again, these results can suggest a reasonable expected range of performance.

3. Go to Control Panel > Power Options and turn off all "sleep" options that shut down the CPU, disks,, and monitors.

4. In "select a power plan" change the power plan to "High Performance"

5. Run the Passmark test again and compare the results.

If you do run and upload this test, I and others here will be able to have a look and make more informed recommendations.

Passmark I think is a weighted test that iseems a bit more gaming oriented, but any score dramatically low will reveal the subsystem on which to focus attention.

The first, simple solution that springs to mind is that Dell may have configured the system at the factory with a power saving scheme that is actually throttling the CPU to almost 50%. It's also possible that a Windows update did this subsequently, as happened to me several months ago with my previous HP z420- one day the CPU performance was halved as an overnight update had changed the power plan!

I use VRay and don't know the way the threads are assigned in Mental Ray, but it may be worth looking more carefully into detailed settings of core allocations, only to be sure. Also, were the results on the two system one at the same size and resolution, that kind of thing.

In any event, if you would list the results of the Passmark test, it may be possible to learn more. Particular attention should be made to the disk system. Was the LSI 2308 and RAID configured by Dell or at your firm? Did you create partitions on the SSD?

We will hope it's the simplest thing!

Cheers,

BambiBoom

I am having the same issue! We bought three of these machines and are having speed issues as well. I have been going crazy trying to figure it out but even the most simple tasks (going through folders etc) are a pain and cause not responding windows. I have qiped the OS and same issue.

I suggest working with Dell, those are expensive systems and should have quality support (business support is often better than home system support).

 

[alex50]

Yeah I tried that and all they did was send a os disc to re-install it. I may have them just come out and replace the motherboards but I just cant imagine all 3 of them having the same issue.
