"Are there some you wouldn't reccommend using?"

Not specifically. It's been a long time since I applied these tweaks to my Vista64 system, but I remember at the time that I didn't think a few of them were going to gain me anything for the task of video editing. I don't remember what those were, but I didn't see anything suggested in the article that would be considered dangerous or detrimental.

[12/23/08 Update: Overclocked to 3.6 GHz (from stock 2.67 GHz) with render times dropping to 52 seconds. Also replaced the stock Intel CPU cooler with a Thermalright Ultra-120 Extreme RT 1366, which makes a huge difference in CPU core temperatures under heavy load.]

I did a slight overclocking of my ASUS P6T Deluxe based system with the Intel Core i7 920 processor from its 2.67 GHz (133 MHz Base Clock) to 3.0 GHz (150 MHz Base Clock). This dropped the render time to 1 minute and 3 seconds (was 1 min 11 sec at default 2.67 GHz speed). A little more overclocking will certainly drop render times below 1 minute, which seems to be consistent with the sub 1-minute times reported by others above.

System specs are repeated below for your reading convenience.

Vegas 8.1
Intel Core i7 920 (2.67 GHz)
Thermalright Ultra-120 Extreme RT 1366 CPU cooler
ASUS P6T Deluxe Motherboard
6GB (3 x 2GB) DDR3 1333
Vista 64-Bit Home Premium
EVGA 01G-P3-N959-TR GeForce 9500 GT 1GB
Antec P182 case
~$1700 system (inclusive the above, plus video card, two HDDs)

2:46 (166 seconds)

E8400 @ 3.6Ghz with 2GB of DDR-1200 RAM and Windows XP Pro.

Update:

With Vegas 9 and 64 bit Vista and 8 gig of ram, the render time is 1:41 a huge difference.

=============================================
I need some help here.

I've run the hdv render test a few time on my Dell XPS 420 which has:
Intel Quad cpu Q9300 @ 2.5 ghz
4 mb ram
Vista 32 bit
Vegas 8.0c build 260
4 render threads
RAM preview 128
Nothing else running, no virus software, and Vista tweaked to run faster.

I get slow render times of 4:09
On one render I watched the Resource monitor and it said the CPU was 100% but the memory was at 37%

Any help why?

Try increasing the preview ram to 512.

2 x Xeon Quads - 2.8Ghz
8 GB Ram
Striped dual sata's
QFX 1700 etc - pretty much the same set up as "xstr8guy" except slightly slower cpus.

8.0c - 63 seconds
8.1 - 54 seconds (16 threads)

Bang for buck the i7's seem to be better value - but for sheer grunt the Xeons still seem to reign. I've run the test a few times and checked the settings and these times are correct.

1 minute and 10 seconds.

New Core i7 Computer (Built Yesterday)
920 CPU
Vegas 8.1 64 bit
No Overclocking
Asus P6T Motherboard

Antec P182 Case
Corsair 625 Watt Power Supply
Nvidia 9500 GT Graphics
Dual Display 30" HP LP3065 * 21" HP f2105

I increased my Dynamic RAM preview from 128mb to 512 mb, and the render time went up to 4:10.

I tested my RAM and it's OK.

Does anyone know why my times are so slow, and how to improve it?
My cpu specs are in the post above.

OK, no response, how about this:

How about sharing your Vegas 8.0c and Vista preference setup configurations?

Try using msconfig to temporarily disable all startup applications and to disable all non Microsoft services. Reboot and then see if render times improve dramatically. If there is a dramatic improvement, start selectively enabling the services and startup programs to determine possible non-Vegas causes.

If disabling the above has no effect, then you can look at other possible causes (e.g., HDD configuration issues)

I do not use Vista, so I cannot help you Avanti, but your computer certainly should be faster than mine, even with the lower clock rate.

rtbond,

I tried what you said, and no joy. Same time.
I also tried saving to an external USB HDD and it was the same time.

There are a ton of microsoft services, do you know which are not needed?

Any more ideas from anyone?

Check your veg file on the timeline. if you do not see all of the multiple tracks, etc. you have the wrong file even if you think you have the correct file. There were a lot of these veg files flying around this forum.

I upgraded to vista ultimate x64 on my workstation and reran the test using vegas 8.1.

render time = 1:52 (about 10% faster than 8.0b on XP x64)

Q9300 @1.175 V
8gb Ram
Asus P5Q Pro
Ati 4850
1 x WD 320gb system drive
2 x WD 640gb (raid 0) render drive

Michael,

What does the "@1.175 V" refer to?

It appears to be the CPU core voltage level he is running. This would indicate he is overclocked by a fair bit.

This is an off-the-shelf Dell Studio XPS i7

Vegas 8.1
Vista 64-Bit Home Premium
Intel Core i7 940 (2.93 GHz)
6GB (6 x 1GB) DDR3 1333
ATI Radeon 4850, 512MB
750MB HD
Blu Ray/DVD burner

~$1900 system includes all of above and a monitor. But I upgraded to the 2408WFP which is working nicely. I am using an existing Samsung 912n for my second monitor.

I ran the Rendertest-HDV in 58 seconds. I've not done much tweaking but did try the following and got NO CHANGE in render times.
1. Moved RAM preview between 128-800.
2. Turned on/off virus protection.
3. Rendered to my OS/program HD, and then to second HD (no Raid in this system)

All 8 cores (hyperthread) were running close to 100% throughout the test. There was some page file activity which surprised me. I will be moving the page file off to a separate fast drive when I install it this weekend.

I loaded up some 720p60 AVCHD and it previewed real time (but I can't remember now if I was on Best). This brought my previous PC (Pentium 4, 3GHz) to its knees even on draft.

So far, so good.

Just a follow up for anyone considering a motherboard upgrade

I bought 4 Gigabyte brand boards.

3 out of 4 were BAD right out of the box.
Yep. Sad but true.

Finally the 4th one worked.

For 2 months, then died.

I RMA'd it back to the factory and they sent it back saying a corrupted bios.
Gee whiz, how did THAT happen? Wasn't me, because one day it worked,
then it started to die, then it died. I think they are full of crap.

I bought another Asus board and put the gigabyte in storage-- I won't even sell it to anyone.

Asus was my last machine, and I sold it to a friend and it's still going strong after 5 years.

My current Asus board shows no problems.

The moral-- avoid Gigabyte like the plague unless you think you are luckier than me.

Cheers
Neil

Looks like the i7 is the way to go next time I update my computer but I'll wait till the CPUs/Boards/DDR3 drop some in price.

Hmm, when I enable the performance boost option in my motherboard's BIOS, the system overclocks on a bit on the fly when under load. New timings:

Vegas 8.1 x64 = 57 seconds
Vegas 8.0 32-bit = 1:31

Intel Core i7 940 2.93+Ghz

12GB RAM
