    Managed to obtain 89 sticks of M391B2873GBO-YH9. Binning data coming Soon™.

    If I can find a financially viable way to get these ICs swapped to a better PCB, I absolutely will. That'll come after binning, though.

    I'll need to keep tRCD, tRP, and tCL binning all separate.

    Charles, can you post pics of label and IC mark of them?

    Think my memory is solid, should be good for above 2666 8-12-8, IMC is dragging behind. Also, would like to try a chip that can do 50/50.

    Very interesting setup there Charles, full bank slots and 2450 7-11-7 with tCWL 6, producing fast 32M result.. BDBG ICs there?

    RTL too tight maybe?

    Some sub timings are different also.

    I wouldnt use geekbench3 memory multicore without all the cores to be that accurate, as you can see the single thread is higher on gigabyte at those settings. 

    Hi Allen.. About RTL, the board set 37-38 it self, I didn't touch anything, but when I try to loosen it to 38-38 or 38-39 it wouldn't post.. As you wish @Splave, below are scores with all cores and HT enable with OCF's timings:

    Gigabyte Z590 Aorus Tachyon *Memory Multi-Core GeekBench3* Low Score at Gear2

    in Comet Lake (Z490) & Rocket Lake (Z590) OC

    Posted

    Hello everyone,

    I don't know if other user also noticed this problem, but before I decide to write a thread here, I did some testing especially at Gear2 which I feel need more tuning from Gigabyte BIOS Team. Btw I have no issue at Gear1, Gear1 on Z590 Tachyon is flawless both on Single-Rank and Dual-Rank, even managed to get +100Mhz uncore compared to the others board I have. Long story short, I have 2 others boards here (Z590 OC Formula & Maximus XIII Apex). I noticed that OCF and Apex scores on par each other, for example 4800MHz C14-13-13 around 11600-ish Memory Multi-Core GB3, but not with Tachyon, Tachyon scores 11200-ish which is roughly about 400 points less than the others. I did some walkaround to the Tachyon's submission on the HWBot, and I can say that some OCers also face same issue with mine and I am aware that Memory Multi-Core pretty much doesn't bring huge impact to the overall GB3 score. Here I did some testing on OCF (sadly my XIII Apex already sold) and try to make comparison what is going wrong with Tachyon.

    Note:

    I use 2 different kits, F4-4800C17D-16GVK and F4-4000C15D-16GRTG because the GVK not working pretty well on Tachyon

    I am not tied to any board vendor, all the stuff here comes from my own and I have no intention to say bad words to any board vendor

     

    Z590 OC FORMULA (BIOS 1.27H)

    *) 4800MHz 14-13-13 (Base on memory profile each board) 

    GeekBench3

    Z590 AORUS TACHYON (BIOS X2G)

    *) 4800MHz 14-13-13 (Base on memory profile each board) 

    GeekBench3

    As we can see, AIDA64 shows that Z590 Tachyon has much lower Copy-Bandwidth, roughly about 5000MB/s less compare to Z590 OC Formula. And in GeekBench3 Memory Multi-Core score breakdown, mostly OC Formula scores better than Tachyon. I did some initial testing also with AIDA64 at 5066MHz 15-15-15, and result is the same, 77K Copy-Bandwidth for OC Formula and 72K Copy-Bandwidth for Tachyon (I forgot to take a screenshot, maybe will test again later). From my personal assumption, I don't know maybe Gigabyte BIOS team choose to loosen some hidden timings for high frequency memory overclocking. Anyway, thanks for reading my thread.

    Holy shit, GTL is easy to use and works so well, thx for linking!

     

    On another note, has anyone manged to reliably and consistently train RTLs on the Tachyon? On 2Xg it keeps flapping for me between 68-67 and 55-56 from training to training, which looks like opportunistic Round Trip Latency disable or enable, like you can manually set on Asus, but I haven't found such setting in the Tachyon bios yet.

    When I manually set them to either of the auto combinations above, it only trains successfully in about 1/10 attempts, otherwise fails (55) and enters recovery mode 

    Try to raise SA and IO2 Voltage and lowered uncore freq, i have the same problem too here on Tachyon..
