Civil 3D configuration

post #1 of 5
Thread Starter 
Please review these settings:

The machine: ASUS AM3 M4A87TD (non-EVO); AMD 10h Phenom II X4 975 Deneb C3; DDR3 2000 CMX8GX3M2A2000C9 9-10-9-27 CORSAIR XMS

I am using AutoCAD Civil 3D 2012 x64 for more than the application is intended, and as the 3D model nears completion the performance is approaching zero. The following settings seem to work better than the other settings tried.

CPU 18.5x and 210 bus with memory 1686Mhz; the northbrige is 2950 and hypertext is 2739; all the voltages are auto with the exception of the memory is 1.5v. The memory timings are 7-8-7-24-27-1T. The temperature rests at 40°C and never rises above 50°C possibly because C3D will not go any faster and therefore does not generate much heat.

More info:
While typing this post the machine froze and then gave the blue screen 2x while starting, so I changed the hypertext to ~2300. It had been running fine for a few hours with the posted settings.

please give feedback

I think the memory would do better at 2T and tighter timings.

Hypertransport should be close to 2000. Increasing that bus doesn't help anything and may be causing your unstability. CPU/NB being around 3000 is great. as for your memory, you may be able to try to run that at 1680 at those timings, but YMMV.

Check out this chart: http://www.overclock.net/amd-cpus/59...ram-chart.html

It can help you when overclocking by giving you the multipliers you need to use at a given FSB to achieve a given speed.


Also, I'm not sure how you've started overclocking. You want to try out one aspect at a time. FSB, Memory, Clock Speed, CPU/NB, Memory speed, Memory Timings. I think your current overclock is pretty safe as its a C3 revision processor but if you really want to tune the overclock you have to do it gradually.

Also if you can, fill out your system specs in your UserCP

Thank you iamwardicus, the chart is nice but I have an excel calculator I built for the same purpose.

With several tests I found that increasing the HT bus from 1750 (auto tune set) to 2300 (also auto tune set) reduced the runtime in C3D by half for some ugly process times. It took awhile to find what was causing the change. So, if some is good more is better - right - so I upped the HT to 2739 by setting NB/CPU to 2739 and letting the BIOS auto set the HT to 2739 (this morning I slowed the CPU/NB to 2730 and put the HT back to 2730 and running fine). Then upped the NB/CPU to 3000.

What do you mean by YMMV (I checked urban dictionary); 1) the memory may not last long, 2) there may be stability problems at that speed, 3) performance will just be suboptimal for whatever reasons.

My approach: test various setting with my main 'problem' application, that is C3D - once I found a pattern then set the variable that seemed the core, it was memory response. Then set the other variables (Bus, then CPU/NB, then HT, and last multi) at the highest stable setting.

billbartuska - will give it a try, before I start thrashing - what timing should I expect at 2T

A question, are the voltages OK on AUTO?

by YMMV I mean no. 2: The AMD memory controller is usually pretty good up to 1600mhz, and since you've a C3 revision chip you should be fine, but stability can be an issue the higher you up your memory speed. regardless, nice OC :thumbsup
