Also, thanks for the tests. I'd be interested to see the 920 bumped up in vcore to match the 860 (even if it's not required). This way we would have an absolute apples to apples comparison... Well as close as possible anyway. My suspect is that the 860 would still be a little faster and more power efficient. It is a newer design, after all so we can pretty much expect that.

Great work here, folks!
Will look into the PLC and IMC voltages at the next opportunity.

I understand where you are coming from but if my 920 is average in terms of voltage required to meet 4GHz then this is an advantage over the volt hungry 860. Besides I dont think I want to put 1.4 VCore on my 920 for an extended period

You own the 4 gig point since I can't seem to get there with my 860...

It will be interesting to see how the QPI alone affects the runtimes. Now you have two rigs with just a QPI boost running. I'm expecting it to make a noticeable difference.

After this are you planning on pushing out the RAM timings on the 920 to match the 860? Or the other way around, reduce the RAM timings on the 860 to match the 920? I would think it would be easier to push out the 920 and still have a stable clock than to pull in the 860.

Hehe, maybe we should hit the team up for a couple of XS lab coats with all this science going on here....

Rock on Emu

Yeah mate I thought mine was a dog when jcool suggested less VCore. Have you tried MOAR VCore

Well the 920 crashed overnight with the increased QPI so I guess just adjusting that and nothing else wasnt enough Off to do my HUET today so no time this morning, it will have to wait till this arvo.

Memory timings is next on the list after this one. Then PLL and IMC as Vinas suggested then I'm going for max clock with stock VCore

Oh and I am only doing this for the t-shirts There is t-shirts right?
