overclocked core i7 good for rendering?

the i7 is the best bang for buck. Its pretty hard to justify the xeon when the i7 overclocks so well.


However if someone finds a dual xeon motherboard that can overclock... that would be better

um... I was responding to the comment you got from overclockers:

....we can do the bundles with more RAM, however you'd risk having no overclock on the bundle - so there's really no point in going for it, truth be told. It's a choice between the RAM or the overclocked CPU. ...

it makes no sense unless they mean the cost to set it up

I agree that the i7 is a great solution at it's price point but looking at the frybench stats the Xeons are performing significantly better. When you Look at the most recent Vray Benchmarks (which are not as up to date as frybench) some of the i7's stack up pretty well against the Xeons. However it seems like the current Vray benchmark does not work the processor as hard as the frybench test. Additionally there are so many variations with Max versions and Vray releases that alot of the speed differences can be explained by those elements.

I feel that we need to increase the resolution of the current Vray benchmark so that it gives the processors a longer work out. The current test is over almost before it begins with these new processors. This may not allow the test to run long enough to see the real benefit of the additional cores that Xeons have.

frybench uses a stand alone application for the test which does not use Max. Everyone uses the same software release for the test which is much more controlled than the current test we have for Vray. I know Vlado talked about a stand alone Vray test some time ago that would be a great tool!

hey

I agree, i think a stand alone test would be fabulous. It would also drive more people to the site in my opniion it would benefit chaosgroup in a whole.

The VRayBench is actually a mini-Linux installation that you can boot up from a USB drive or a CD, so that things like the operating system and other loaded applications/services are also singled out. This works well, but the problem is that you need to set up your network manually to upload the results.

lol. i remember when i first sent my tower to be tested outside of max in the alpha testing stage. And after all these years it was good to see it pop up in the vray RT seminar you had

[vlado]

Yep, it is in fact a very good test scene Thanks for letting us use it!

The more ram you have, the harder it is to achieve a stable overclock. Every additional ram-card increases the likelyhood of mistimings. At least that's my understanding of the issue!

ahah - never would have guessed that!

I had 12 GB of ram, and an overclocked I7 and ended up busting the CPU thanks to trying for too much so be careful
I had gone from Water to air By the way, and wasn't used to the limitations, that's how i set it up wrong.
Not sure if it was related but it also made a pair of Sticks Fault (instant crashes during intense renders)

Is this available for download?

With 12GB and an i7 920, I went straight for 4.2ghz. It was stable...ish.... ok it wasn't stable, and after a few weeks of trying out different settings, I found some golden ones for 4ghz, and it's been rock solid since.
