Thumbing through a magazine at a shop earlier,
It said that if you disable the on-die GPU you are also disabling the new instructions.

So is it [I]really [/I]overclock OR new-instructions, or did I mis-read?

edit:
Let me rephrase that, it said if you are using a discrete graphics card.

Yes that is correct the P67 Chipset requires Discrete Graphics aka a PCIe Video Card which fully disables the new Quick Sync Video Transcoding (and all of the on-CPU Video).

For H67/Z68 which has video outputs on the motherboard, I've been told that on-CPU Video still works when you have a PCIe Video Card plugged in as well making this great for 3-4 monitor setups.

AVX the 256-bit FP instructions which offer a possible 50-100% performance increase for Prime95 are not affected.

Ah, that's where I was getting confused. Thinking AVX was part of Quick Sync.

Thanks. :smile:

On the topic of HT v non-HT: I find when running apps like prime95, the machine is more responsive with HT if the app is using 100% of the real cores. With the options in prime95 - it's quite easy to distribute the load across the real cores.

George/anyone else,

What's the noise level like with the stock cooler at full load?
(I'm considering getting the i7-2600k. I assume the cooler is the same as the i5 2500k.)

Thanks!

As this will be purely for prime stuff I am hoping to use Ubuntu rather than buy Windows 7. Is it likely to be able to install mobo drivers? (Gigabyte GA-P67A-UD3P, probably.)
I will be using a discrete gpu (2 yrs old) so am hopeful there will be drivers for that.

I don't think that Microsoft's idea of mobo drivers applies to *nix - it just works there. Then only moment I recall when I had to check my mobo chipset info was when I wanted to install tempereature monitoring software, and that was years ago and on gentoo. There's an extremely high level of certainty that you won't need to bother about mobo drivers on linux.
As for the gpu, do you imply using it just for 2d diplay stuff or you mean gpgpu computing ?

Thanks. I wasn't sure because I assume the P67 chipset came out after the last Ubuntu update. I don't speak *nix!

The gpu is just for the display, I might look into gpu computing later.

[QUOTE]So if you find yourself with a new Intel P67 motherboard and the latest Core i3/i5/7 processor in January, you should be able to get the system up and running on other late Q3'2010 or Q4'2010 Linux distributions such as Ubuntu 10.10.[/QUOTE]
Apart from that, my understanding is that even if a given chipset's release date is younger than the one of an OS then within basic usage constraints all computers run the same and the OS will start, possibly using best match settings - with the details making difference only when some specific stuff (presumably like integrated graphics, energy saving,..) is being used.

As for the gpu then even if it was some exotic brand/model then it will be defaulted to some VGA-compatible modes, otherwise you shouldn't encounter major problems (after all for mprime you will only need a console with a command line).

Linux doesn't bite and I hope you will enjoy using it, hopefully soon noticing the [URL="http://widefox.pbworks.com/w/page/8042308/Kernel-Comparison-Linux-vs-Windows"]advantages[/URL].

Thanks for finding that.
I tried Linux once before but only for a while to do some 64bit seiving. Didn't really get into it in that time. A strange alien landscape!
Nothing to lose but my chains, right? :smile:

Seriously, I heartily recommnend using a number of different operating systems to become familiar with them. You don't need a number of different computers to do so. With a virtual machine package (VMware, VirtualBox, etc) you can even run all the different systems concurrently on the same hardware.

New build coming tomorrow. :smile:

Without Windows for the first time since 1993 :max:
