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 really overclock OR new-instructions, or did I mis-read? edit: Let me rephrase that, it said if you are using a discrete graphics card. Last fiddled with by Flatlander on 2011-01-21 at 20:09 |

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. Last fiddled with by abstractalgebra on 2011-01-22 at 02:41 |

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! edit: 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. Last fiddled with by Flatlander on 2011-01-25 at 20:41 |

As for the gpu, do you imply using it just for 2d diplay stuff or you mean gpgpu computing ? Last fiddled with by tichy on 2011-01-25 at 21:08 |

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. Last fiddled with by Flatlander on 2011-01-25 at 21:21 |

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 advantages. |

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?

Eggheads of the world unite! You have nohting to lose but your yolks.
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. Paul |
