most of you must be wondering: how about disable Core Multi-Processing in the BIOS?

I've just disable it now and running the benchmark, let's see how it perform.

I've disable Core Milti-Processing in the BIOS.

Core-Duo is now Core-Solo:

As you can see, the Core-Solo's 3DMark05 score is very similar to Core-Duo, most likely the 3D applications are more depend on graphics card, so gamers, if you are playing 3D Games (not on Z62F but maybe Z96J)you might want to disable Core Multi-Processing in the BIOS and hopefully(not sure but I think it will) that'll extend some battery life, but for applications you might want to enable Core Multi-Processing for better performance.

I hope all the information helps.

Ken,
Thanks for th einfo. Very helpful. I thought Core Duo's chipset automatically shutdown the second core when it is not in use to save energy.

Yes according to Intel, but you can also disable it in BIOS.

3DMark 06

1st test with Core-Duo Disable:




2nd test with Dual-Core enable:



The result is almost indentical, 3D games seems doesn't take any advantage of Dual-Core technology.

I think we'll find that is common until they are specifically designed around dual-cpu setups. I don't think any games have yet been made to run different processes on different cores.

Yeah, or single chip but Dual-GPU, hopefully they'll soon launch mobile version:

"Dear Partners,

Today ATI launched the CrossFire™ Xpress 3200 chipset formerly known as the RD580. This is the first chipset that ATI has designed from the ground up for the gaming enthusiast market and the industry’s first single-chip 2x16 PCIe controller. This now means that the industry’s fastest graphics card—the Radeon® X1900—has the fastest dual GPU motherboard to support it in the market. The ATI CrossFire platform has claimed top performance in dual graphics.

Following on the heels of a hard launch of the Radeon X1900 cards, ASUS is also announcing immediate availability of A8R32-MVP DELUXE motherboard featuring the CrossFire Xpress 3200 chipset. DFI, Abit, Sapphire and PC Partner will also have CrossFire Xpress 3200 motherboards available in March. This is the best multi-GPU chipset that has ever been build and I highly recommend that you try it by contacting one of the motherboard suppliers.

So far the technology press is very excited about ATI’s CrossFire Xpress 3200 and Radeon X1900 combination with quotes like:
“With the introduction of RD580 ATI will have a single-chip dual x16 PCIe Corssfire solution to compete with nVidia's top-of-the-line dual x16 PCIe chipset. With a competitive chipset, the fastest current video card in the X1900XT, and the end of paper launches, ATI has had a great start to 2006.”


"In terms of dual-GPU-performance the new Crossfire set a new mark and beats comparable SLI-Configurations by up to 18 percent. When comparing Super-AA against SLI-AA this advantage widens to an impressive maximum of 86 percent."
Multi-GPU is becoming more and more mainstream in the graphics market. CrossFire Xpress 3200 with its 2x16 architecture enables excellent connector-free CrossFire via the PCI Express bus that makes a very interesting price/performance point for gamers on a more modest budget. Combined with our X1000 series and the already announced RD480, we now have a full range of CrossFire Platforms addressing multiple price points and needs."

I wonder how that would work. Since a single threaded game would probably take up something like 100% on one CPU, that would translate into the OS thinking that there's a 50% CPU load. Would that cause the other core to power up? I had the feeling that only under very light work loads did the second core shut off. That could be an interesting test. See if there's any battery life difference between running a single threaded app full out and turning one core off and running full out again.

Nice!

I noticed the 3945 ABG has different interfacing design. Old 2915 ABG will not fit!

That is correct, 3945 is smaller than 2915 and also the slot is different.

yay!

You got some numbers wrong...
