I just upgraded my comp to super fast six-core i7 3930K with 16GB RAM and GTX 470 RAID (approx 200MB/s R/W); it is auto tuned by Asus to 4100 MHz. It behaves very strange...when rendering in Vegas 10e cpu goes down to 126.4 BCLK x 14-20 which translates to max 2528MHz!!!! It is a FEW times slower than my lenovo W520 (with Quadro 1000M) using Vegas Movie Studio rendering same files. In terms of CUDA cores both systems are similar (maybe GTX470 has even more CUDA). I rendered MJPEG files to MainConcept MP4 and it was just a few frames per second. When switched to Somy MP4 pre-set it was faster but still much slower then on laptop. What is going on?
Any thoughts?

Turn off all overclocking, then see what happens. If that doesn't help, move your video files to a different hard drive, see if that helps. Turn off all GPU accleration.

It is same with or without OC; hard drive is 200MB/s faster is only SSD; how to turn off GPU acceleration in V10e?

Preferences...does movie studio have GPU acceleration? Not sure...it might not.

I am using Vegas 10e; (movie studio - which works faster - is on y laptop)

Do not use asus autotune for OC...
Asus will change the BCLK. That will OC the whole system of yours like hard drives, RAM and PCI-E slots... Can be dangerous if you dont know what your doing...
Use the multipler with Sandy Bridge and Ivy Bridge... Thats really easy to do. In BIOS, go from the original (3.2GHz) to lets say 3.8GHz, specially if you dont got an third party cooler for your CPU...

And what do you mean with this: "and GTX 470 RAID (approx 200MB/s R/W)"

Do you mean you have one GPU (GTX 470) and you harddrive is in raid doing 200mb/s ??

Check if all cores/threads is being used when rendering....

Be sure that Windows power options is at full (no saving options on CPU maximum).

Do you mean you have one GPU (GTX 470) and you harddrive is in raid doing 200mb/s ?? _ yes

so shall I use manual OC and choose higher bclk keeping the multiplier to 33?

it is strange - when I start rendering in first few seconds system renders fast at full speed and then after few seconds thought that it slows down keeping bclk same but lowering multiplier. I thought it is related to cpu temp (70C) so system will slow down trying not to overheat cpu but when I increased cpu temp limit to 88c it does the same at 70C. (that heppens regardless if I choose cpu for render or cuda)
any suggestions

I did it manually; 100x40 - it was rendering holding it for a few minutes and after that it is fluctuating again (going down to 100x31).....

You need to get your system stable first, get Vegas running right. Overclocking is the last thing you should do with a new computer, not the first.

Go back to stock values, DO NOT OVERCLOCK AT ALL until first you know your computer is running right.

Everything should be perfect on your computer before overclocking.

Is your RAM speed set correctly for your RAM? You need to get the basics down before overclocking. If you do not know anything about overclocking you should NOT overclock until you go online and read up on it first.

Jeff and Kim,
you are right I agree with OC and great point by Kim about frequency for PCI devices. I will go back to basics.
What I am trying to find out is why system is slowing down when rendering with Vegas 10e - it starts ok and then slows down reducing multiplier sometimes to 20...
I played with memory settings for dynamic ram preview but it is still the same; hard drive is fast raid...it happens regardless if I choose cpu or cuda for render. any ideas?

When cpu temp gets too high, it will lower clock speed by itself. You said you had 3930k, if you tries to overclock that cpu without a third party cooler, that will raise your temperatured to the roof! Stock cooler is already showing high temps without any overclocking. Think 3930k has a TJ max 105 celcius. But before that it will throttle itself down trying not to shutdown the computer..

OC with stock cooler from 4GHz is really a no no.. :\
Like Jeff said, render first without overclocking and try to solve your problems first

But it sounds you having to high temps on your cpu therefor it throttles down trying to avoid shutdown.

Download coretemp or realtemp or anything else..

I don't know it help or not. But did you update the bios? Since I got my system working rock solid @4.6Ghz. SO I am gonna tell my first hand experience over view. My 3930K ran stock clock prime95 stable. I also did try auto tune and It got up to 4.3Ghz and prime95 stable but I don't like auto tune because it is down clocked my ram @1866mhz to like 13xxx something. So I did manual tune. I spent probably over 10hrs of tweaking it. I got a lot of crashed before I got mine running stable. So, you just need trying different thing to get it run stable.. Good luck.


You need to monitor the cpu.. Realtemp and CPU-Z to monitor the Core speed. When you load (prime95) and your cpu load 100% and if it gradually down clocking, then you need to shut down (kill prime95 and get back into the bios do more tweaking.

Bruce,
What are your bclk and multiplier, ram frequency settings?

My BCLK IS 100 mulitiply 46. I don't remember the other detail and I am not at the computer right now. I will post here for you tomorrow. I think your problem is mainly about your Vcore voltage is not good. Every chip run slightly different in voltage requirement.

Marius, search for OC settings for your board on the net. You are overclocking without proper cooling, without knowledge of what you must do.

Your RAM speed, voltages, cpu speed, etc, affects each other. You should stop trying to overclock until you get a new fan. Your processor runs hot to begin with.

1. Go back to stock settings.
2. Get a new fan, research it and pick a good one.
3. Research OC settings for your board in the overclocking forums.
If you are new to overclocking, you must research it and learn the basics.

I have pretty good fan....Noctua NH-L12 120mm & 92mm SSO Bearing PWM Fans CPU Cooler - Newegg.com (http://www.newegg.com/Product/Product.aspx?Item=N82E16835608025)

still I am trying to figure it out why comouter slows down when RENDERING VEGAS; it could BE temperature (it is just my blind guess) but it happens approx at 69C which is not that hot...any guess; comoputer is NOT oC now

Well first of all.. maybe we got u all wrong from the beginning.. When you rendering to a video output with Vegas Pro, the software does not rendering in the exact same speed from start to finish...

It does depends on the content in your project...

For some content in your timeling, Vegas will rendering using 99% of your CPU power...

While sometime it will use 40%...

I guess it has some playing which format/codec you also choose.

But ofcourse your new system would be 4X times faster than you old laptop...

Step 1: Reset your BIOS to factory settings. You might did some other changing without remember.

Step 2: Check with Windows Power options if some power savings is set to ON.... In that case change to maximum performance or whatever.

Step 3: Try another application like After Effects or Prime95 and se if those softwares also makes your multipler jumps down when rendering/stress...

That is the best fan, good choice. Sorry, thought you had stock fan.

Jeff, we have to have an discussion about whatever if thats the best fan or not.. =))

I had this one but returned and now I regret
SilverStone Heligon HE01 CPU Cooler with 140mm fan for Intel socket LGA 775 / 1155 / 1156 / 1366 / 2011, AMD socket AM2 / AM3 / FM1 / FM2. Copper base heatpipe and Aluminum fins - Newegg.com (http://www.newegg.com/Product/Product.aspx?Item=N82E16835220047)

I have 100 bckl 44 multiplier, all power savings things are unbloked , cpu temp during rendering 69C, fast raid 150-200MBs and it renders 19 minutes 1440x1080 project (only color correction filter appilrd) ...49minutes!!!!!!!!!!!!!! ridiculous

Marius,

My DRAM Primary Timings is 10-11-10-30-2.
Secondary Timings I leave them in AUTO.
CPU Vcore Voltage Manual Mode>
Manual Voltage 1.300
CPU UCCSA Voltage>
Offset Mode + .020.
DRAM Voltage I set my 1.5V. The rest I leave them in AUTO.

Enhanced Intel SpeedStep Technogoly> Disabled

CPU C1E> Disabled,
CPU C3 AUTO CPU C6 AUTO CPU C7 AUTO. .

DIGI+ Power Control> CPU Load Line Calibration > Ultra High
CPU Power Duty Control> Extreme. All other I leave it in AUTO and 100%


If you got the same board as mine, you should try this settings, see how it do. I am running 7 fans I set them all to high. My system is very quiet I am very surprised such a powerful system and operate so quiet.
