    [FS-EU] Hyper 1866c7 Corsair pretested

    in Sold

    Posted · Edited by ground

    Small pricedrop on the 1866c7s. Open for trades for strong x58 chips. Added a couple more tests. If there is something specific you want tested with this kit I can do so, IMC I have here is strong enough to run anything hyper can run with relative ease.

    Selling a triple kit of 1866c7 Corsair Hypers. These sticks are from two different kits; one stick is an older "best stick of a kit" I am fine without, the other two are the living sticks from an average kit (third stick was DOA, can include it for collection value if you want). These sadly struggle with stability at higher frequency as far as I can tell, since I couldn't manage to complete a run of 32M at 1050 7-7-6-20 at any voltage, nor 1100 7-8-6-22. The 0936 stick is stronger (1000 6-7-5 1.95V; 1090 7-7-6 1.85V) and has no such scaling issues. 
    32M 1000 6-7-5-20 2.0V
    32M 1000 7-7-6-20 1.68V
    32M 1052 7-7-6-20 1.85V
    32M 927 6-6-6-18 1.95V not minimized, just checking max freq 6-6-6-18 32M
    8M 841 5-6-4-20 2.05V not minimized, just checking max freq 5-6-4 8M
    1M 1052 6-7-6-20 2.05V
    1M 1188 7-8-6-22 2.0V
    Valid 1272 8-9-8 1.9V 

    Retested 7-7-6 32M and 7-8-6 1M again, now running much better.

    Mad ! Benchable at some point? Insane result

    stability is pretty much all gone over ~1650, and dual channel is impossible. This is only possible due to the x58a-oc allowing to set lower uncore clock if you use the innermost channel. It is possible to run 16x mem + 17x uncore this way. 

    This CPU tops out around 1400 32M on R3BE with typical uncore ratios and is the strongest IMC I’ve found on this platform by a fair amount. 

    So far I’m only running some timings manual, I recon ~30-50 MHz more might be doable without increasing volts by a lot, since with full manual timings since gdie appears quite sensitive to that, at least on z87 this stick did. I also have 2 more sticks to try as well as a couple more tweaks I’ll be keeping to myself for now.
