    Menthol, the cherry picked CPU is predictably a J batch. Don't recall where it was made. Won't be taking it off until the Phobya cooling shows up so I'll have a look then. The CPU I used for my RB score that Arne just passed for 2nd place is a Malaysia L batch.

    As far as finding a quantifiable difference between the two CPUs, under air, I can enable the J batch cores one at a time and bench 4.9 on all of them. With the L batch, the individual cores benched between 4.7 and 4.9. However, once I pulled out the ice bucket, I got the L batch CPU up to 4.86.

    Your 4.6 figure on less than 1.3 volts seems on target. If the Phobya doesn't show up today, I'll try to see how low I can take the voltage at 4.6. Considering I got 4.65 at 1.325 on AIO, the 4.6/1.3 figure might be obtainable. Once the Phobya cooling arrives, all bets are off since my J batch was binned for best of best.

    My 4.8 capable chip does so at 1.36-1.37 (I really don't want to push it further than that anyway). The funny thing is that lower than 1.3 @ 4.5 or 4.6 (doesn't matter), I eventually (day to weeks). Even funnier, is that the crash occurs under light load (cold to first use speed step - first key-strokes to spin up after idling all night).

    Wondering if maybe I am tweaking the wrong voltage to squash whatever it is that causes long-term instability?

    Wondering even more if I'm still getting gremlins from SLI + 10GbE + M.2 under linux. None of those things has struck me as terribly well worn paths, less still all in one place. I had to do the PCIe dance a few times just to prevent random boot hang-ups for resource contention (m.2 and 10GbE card don't appreciate eachother's company AT ALL).

    I may swap the strix GTX980's out for the 980ti lightning and walk those voltages down this weekend. It would be frustrating to lose the Cuda/openCL power, but good to know if I am pushing more voltage than required for the processor because my PCIe cards are fighting eachother.

    Sounds like the speed step then [Edit: said with the confidence of someone who doesn't have to deal with the problem]. I turn all that stuff off since it only costs me around 40 watts at idle. I just turn off an extra light and the power company is none the wiser... Until I crank it up and the entire grid sags under the load.

    Could also be the PSU. Not the top-end but the bottom. These experiments take weeks as the failure takes that long to show...

    As for speedstep, it isn't the money or the planet, just want to help ensure that when I retire the chip because its obsolete, not because I baked it doing nothing overnight when I didn't have to. Some nights, many nights, I do need to bake it.

    So did Arne move back out in front? I bet that sneaky guy was holding back all along laughing at us

    Yea, the little sneak moved back ahead of me into 2nd place. Was messaging with Arne earlier and he made an interesting observation about the Xeons up at the top. The leaderboard shows them both as 8 cores, but the two motherboards are DUAL XEON boards. Now we know where those monster H.264 scores come from!

    Just made some interesting stress test runs on my cherry 5960X. At 4.6 GHz and 1.200 volts, it BSOD at the login screen. Bump it up to 1.253 volts and it chugs right through an hour of RealBench stress test at 4.6 GHz. I'm still trying to figure out what to make of a 53 mV difference between a BSOD at login and a successful one hour RB stress test stability slamming HandBrake among other things. Hottest core topped out at 77°C on AIO cooling.

    My older 5960X does 4.5 GHz at 1.300 volts, so 4.6 GHz at 1.243 volts is pretty sweet.

    The guys who sold me the Phobya unit had it listed as in stock. I sent them a note today because I'd not yet received a shipment notification (paid for it last weekend). They wrote back to tell me that they didn't have the item in stock, but were having it shipped in and they'd notify me when they ship it out. Apparently the term "In Stock" in an item description is open to considerable interpretation these days. Oh well, it's not like I've never BS'ed a customer or two on getting stuff shipped here from Germany.

    What cache freq/voltage, if I may ask?

    cekim, Cache was running (I think) 4.2 GHz set to auto. I've been able to run the cache and cores both at 4.8 with stability, but that takes a lot of cache voltage and extra heat to deal with for not so much advantage. Right now I'm really frustrated with the AIO cooler I'm running while I wait for the Phobya. Sure, I can get an ice bucket nice and cold, but if the pump/block don't assault the thermal interface with a brutal water flow and smart engineering, it's all for naught. AIO just isn't up to the job where the rubber meets the road. I'm sure if I somehow cracked the AIO block open, my first word would be "wow", and not a good "wow".

    Menthol, USA, Southeast, though any given week I can be working anywhere in the US or occasionally Germany.
