Overclocking

Has anyone tried Vegas on one of these overclocked machines?

http://www.uberclok.com/

Is there any advantage? Disadvantage from a Vegas-centric standpoint?

Speaking theoretically, (good) overclocking = faster processing speed = better preview frame rate and better rendering times.

In practice, you might open up a processing speed bottleneck only to find a disk throughput bottleneck.

I notice that the Reaktor is built on an nVidia mobo. A buddy who has built a few machines for Vegas is pretty much done with anything other than an intel proc on an intel mobo. His ASUS SLI mobo (built on nVidia chipset) does give him a platform for 2 graphics adaptors and 4 monitors, which is very cool, but, he feels he has paid a price in stability and compatibility.

Some folks have reported rendering failures due to thermal overload... Vegas will push the processors for extended periods during rendering. Overclocking does generate more heat.

Having said all that I've never tried it, myself, and overclocking does work for some people.

The life of one of those PCs is far shorter as it's pushing the processor and possible failure is guaranteed far earlier than usual.

If you have an OEM chip, don't overclock. Retail chips, however, overclock nicely and with the right cooling, you don't shorten the life enough to kill it before it goes obsolete anyway.

Trick is, BUS Speed. In one of my machines I have 2GB DDR2 800, but clocked down so I can raise the BUS speed and keep the memory still at spec or just below. That machine has been overclocked for several months and is used a lot in gaming and video rendering.

I just upgraded my PC from Core2Duo E6400 (overclocked from 2.4 to 3.3GHz) to the latest E6850. The stock E6850 is slower than the overclocked E6400. The OC E6400 was working fine with Vega. You can find a lot of info in Google search with "E6400 eVGA 680i overclocking" keywords.

John,

With bus speed concerns, isn't it preferable or even more cost effective to upgrade the PC instead of switching out the board?

It depends on your current config. For me, everthing is new for HDV editing. I used a Dell8300(P4 3.2G 1.5GB RAM) and AP for DV editing until last November. There was much that could be improved, except adding a WD Raptor drive (10000RPM) that I am using now. Using the startup time as a rough comparison, 8300 takes about 1.5-2 minutes from logon to ready for use. OC E6400 is ready to run user program in 15 to 20 seconds (while background processes are still running).
