    Binning data request

    in Intel CPU Overclocking

    Posted

    yeah 7-7-6 1.65V, also with how much voltage they scale as well as max freq with trcd 6 and trcd 7. Some kits can do trcd 7 at ~1120 on ambient but thats pretty rare. tRCD 6 the highest I've managed on ambient was 995 32M though I'm sure more is possible with better sticks.

    I was running 115 pcie and slowmode. I was able to get cpu up to 250 bclk with the multi dropped. 

    damn, thats a really bad core. I usually wouldn't even bother testing further if a chip can't do 32m at 21*214 with 1.4V on air, and even then its a tough sell to bother taking cold, currently I don't bother with anything that can't do 4.5/1.3V, for 920s and W3520s 4.5/1.25V now that I've binned a decent number of chips.

     

    If anyone wants to get into 1366 xeons, in particularly the 32nm low multiplier ones - don't buy batches from 2010. I just went through over 100 of them tonight and only 2 could do 250+ bclk on air. With batches from 2011 I had close to 50% of tested chips manage that...

    My luck with my i7 920 was shit. 4.65 in 32m. I have three more coming but the first two were awful.

    what temps and voltage?

    edit: you are stuck at 221, any chance you aren't in slow mode and your pcie is untouched? you need roughly bclk*0.45 pcie to get beyond 221ish BCLK (eg 118 for 261)

    You don't get what anyone is saying or said. Just ask the simple question, "mobile chips allowed or only desktop" and leave it at that. All you do is look like a know all that causes more friction than solves the question.

     

    I have a simple question @Leeghoofd, is 775 and 771 going to be treated as the same socket like 1151v1/2? or can 771 be run on 775 board like last year? Love your work mate, going to be an interesting one.

    I would hope that for the Superpi Stage 771 chips would be fine, but for the BCLK stage the board matters - so either ignore 771 or find a strong 771 board...

    Yeah, just cut up a cheap dead Asus board with nice heatsinks :D I've used the heatsinks from a dead P5N32-E SLI + the SB heatsink form a P5Q Deluxe with cut heatpipes for my P5E3 Premium and the mounting holes are very similar on the rex, VRM heatsinks fit just fine. SB might need some improvisation.
