Default Re: Non-K Sandy binning?

It may be the IMC too, cause when I was trying to get those sweet, sweet XTU points on an i5 3470 I found that the IMC started performing worse at higher bclk, actually running worse clocks and timings.

I'm runing the RAM on 1333 strap, ie ~1420MHz with CL9... So this limit seems to be the core, also Ivy bridge is very different IMC wise, since it is unlocked to way higher Memory frequencies

Binning the remaining 107MHz CPUs will be done on SS i guess, to see if they scale with temperature differently
EDIT: [MENTION=123936]yosarianilives[/MENTION] IMCs on sandy are limmited to 2133, and so far all that I had managed that... Also my board can only go up to 1,7V Vmem, so 2133 CL7 is pretty much the best I can do
Yep, if i member well on SB the BCLK clocks generation is still linked to the pci-e and other cpu clocks.

So it could not be relevant for latter cpu but for SB BCLK binning is still relevant.
