TAGG Posted November 9, 2017 Share Posted November 9, 2017 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 Quote Link to comment Share on other sites More sharing options...

TAGG Posted November 9, 2017 Author Share Posted November 9, 2017 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 Quote Link to comment Share on other sites More sharing options...
suzuki Posted November 10, 2017 Share Posted November 10, 2017 Would be a miracle if they are all alive. But nice surprise. Sent from my iPhone using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
TAGG Posted November 10, 2017 Author Share Posted November 10, 2017 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 Quote Link to comment Share on other sites More sharing options...
Guest Posted November 10, 2017 Share Posted November 10, 2017 Killing a SB is an hard task! Awesome pic, have fun with these baby's. Quote Link to comment Share on other sites More sharing options...
PKBO Posted November 10, 2017 Share Posted November 10, 2017 not so hard with faulty MB My MSI BIG BANG killed 4 CPUs.. one really great 2600K, solid 2500K and some cheap i3s... 1 Quote Link to comment Share on other sites More sharing options...
suzuki Posted November 10, 2017 Share Posted November 10, 2017 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.

yosarianilives Posted November 10, 2017 Share Posted November 10, 2017 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.

TAGG Posted November 10, 2017 Author Share Posted November 10, 2017 (edited) 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 Edited November 10, 2017 by TAGG Quote Link to comment Share on other sites More sharing options...
yosarianilives Posted November 10, 2017 Share Posted November 10, 2017 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.

TAGG Posted November 10, 2017 Author Share Posted November 10, 2017 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 Quote Link to comment Share on other sites More sharing options...

So it could not be relevant for latter cpu but for SB BCLK binning is still relevant. Quote Link to comment Share on other sites More sharing options...
TAGG Posted November 10, 2017 Author Share Posted November 10, 2017 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) Quote Link to comment Share on other sites More sharing options...

TAGG Posted November 11, 2017 Author Share Posted November 11, 2017 63 i3 2130 done as well, one dead, best two chips do 108.2 and 107.9Mhz (1,35V air) Quote Link to comment Share on other sites More sharing options...
