I have a quick question about locked Sandys, is the BCLK strictly limited by the board, or is there any chance, that the CPU makes a difference as well?

Asking because I'm kinda lazy and someone might know that and can save me the time to bin my 120 i3s

120 pc's ? Omg...

I wanted to buy some more 775 Chips and there were a bunch of sandy/ivy i3s and i5s in the box as well... i guess there could be a worse suprise

Here they are:

Mostly i3 2100 and 2130, but some 3220 and i5 2400 as well

Would be a miracle if they are all alive.

But nice surprise.

LGA chips don't die that easily... so far I have tested 34 i3 2100 (for POST only) and all were good so far, would surprise me if more than 5 are dead

Killing a SB is an hard task!

 

Awesome pic, have fun with these baby's.

not so hard with faulty MB My MSI BIG BANG killed 4 CPUs.. one really great 2600K, solid 2500K and some cheap i3s...

The way are put on the box makes me think they will die ). The have those "pins" in the exterior,i had on one of my skt 775 cpu's falling off in the shipiing box,it was DOA.

It sounds like you should do some testing on if cpu matters and share your results with us but I think that the core may not care so much but you may be able to bin IMCs.

So far I can confirm, that the CPU itsef play a vital role in how far you can go with BCLK, i have tested 30 or so 2100s on my Z77 Professional and so far only 4 managed 107Mhz BCLK for POST, most top out at 106,5, some even at 106...

Binning the remaining 107MHz CPUs will be done on SS i guess, to see if they scale with temperature differently

EDIT: @yosarianilives 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

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

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.

I'm now finnished binning 81 i3 2100, the best three do 108.3,108.3 and 108.1Mhz BCLK on my Z77 Professional (on Air, 1,3V)

Sexy

63 i3 2130 done as well, one dead, best two chips do 108.2 and 107.9Mhz (1,35V air)

Not bad at all.
