slow rendering times with i7 Sandy Bridge
Before the recall I rebuilt a system with the new Sandy Bridge i7 2600K processor, Asus P8P67 Deluxe motherboard, 12 gigs of ram, Win7 64 bit, Sony Vegas Pro 10c 64-bit.
What I found is that my rendering times are SLOWER than my older Intel Core2, Quad Q9300 @2.5 ghz, 2 gigs ram, Gigabyte, GA-EP35C-DS3R motherboard, WinXP, Sony Vegas Pro 10c 32-bit.
I thought I was going crazy for it seemed like my rendering times had not improved. I went ahead and tested a 1 hr 40 min avi file, no effects, one track, rendering it to mpg (for DVD authoring):
with Intel Quad Core it took 54 mins
with i7 2600k it took 1 hr 40 minsthe ac3 encoding took:
with Intel Quad Core it took 8 min 3 seconds
with i7 2600k it took 32 mins 16 seconds (I did it twice!)So the rendering times are taking longer!
Any ideas why? Anyone else experiencing similar results?
I built this system to improve my rendering times.
Thanks for your insights and help! James

You may wish to check on Tom’s Hardware, there was something about Sandy Bridge issues and SATA, just read it last week I believe…may have something to do with it, but just an idea…Good luck!

I am aware of the problems with the sata ports. I do not believe that is affecting my renderling times. Plus I am using 2 of their 6 gig ports which are unaffected by the problems.
Thanks, James

Ummm maybe that’s because the sandy bridge CPUs don’t support hyperthreading??

Ummm maybe you have hyperthreading disabled?

As it turned out I did not have all the correct drivers installed and probably had a few things in the bios set incorrectly. I hired a tech to go over and it is working better now. Much faster than before. James
