    Samsung DDR3 G-die

    in Memory Heaven (air/extreme)

    Posted · Edited by ground1556

    Now we are getting somewhere :D This is promising for more :D 

     

    Edit: Doing more detailed testing right now, it seems like some other timings have a range where they are the most stable at high clocks, at least with my best stick:

    CL: 15
    tRAS: 22-23
    tRP: 17-23
    tRCD: 23-29

    tWR: 12-15
    tWCL: 7-11

    Any higher and they refuse posting, with any of these settings. 

     

    I did manage 3600, but I think I'm running into the IMC limit now. (again, this IMC can't do 2400 with DR sticks)

    Samsung DDR3 G-die

    Been trying around with my best 1GB SR Gdie stick (since for some reason my G3258 doesn't like dual rank at all - can't even post 1200) and this stuff is pretty fun. Still haven't even touched half the timings and voltages and its already doing close to 1800 for max valid at 1.8V (bios limited, probably gonna mod the board at some point). Gonna play with it some more over the next couple days and then take it cold and see where I end up. 

    Couple notes already: 

    - CL15 gave 10-15 MHz over CL14, CL16 doesn't work at these clocks.
    - tras, trp, trcd scale negatively above 23
    - Command Rate made no difference at all (at least not yet)
    - Maxmem with 350 MB helps about as much as going with CL15, 10-15 MHz more (I'm quite unexperienced with mem-frequency (first time I'm trying it at all on any platform), so I'm not sure if this should be general knowledge. Are there any guides for max mem clock on Haswell out there?)

    Set of timings for DDR3 Elpida Hyper

    - 2200 7-7-6 seems to be close to impossible on non Corsair sticks. Not sure if they binned differently or if its the pcb. Triple kits seemed to do better

    this seems to be disproven. I've gotten a kit of Adata XPG+ 2200c8 that easily does 2220 7-7-6 on high ambient (note: my Dom GT testing was on lower ambient). They also skyrocket at 7-8-6 compared to the Dom GTs (2325 vs 2400+, oddly enough higher then I've managed with any other DR sticks on this particular IMC (tested BFR, CFR, Rev G, BDBG, BBSE, BDSE). Sounds like me and the others I've been talking to just had bad luck.

    Team Cup benchmark ideas

    in HWBOT Competitions

    Posted · Edited by ground1556

    Generally, I would support Xeons and opterons being allowed as long as their corecounts don't exceed the non-xeons corecounts. 
    If anyone has ideas that add to these, please do so - these are just some basic ideas I'm throwing in the discussion. Here are a couple ideas I have:

    One sub for each DDR generation (4 subs each, DDR, DDR2, DDR3, DDR4):

    • Max % over stock frequency
    • memory frequency AMD only (alternatively memory frequency, all but optimal platforms (so no 1151(v2), 1150, 775, 939 or at a maximum CL)
    • hwbot prime 30 minutes/corecount

    DDR3 2d:

    • LGA 1156 Geekbench 3 Single Core
    • LGA 1366 x265 4c 45nm/4c32nm/6c32nm (or something else that gives 45nm stuff a usecase in TC - its kinda hard since 32nm is so much stronger usually)
    • AM3 R15 odd corecounts only (3 scores)

    Did you literally submerge it in LN2?

    Jup. Stuck a wire through the corner hole and hung it in. Though I tried it again recently and it won’t post anymore in my rampage 2 (we tried it in an Msi board, so maybe that was the reason it posted at all), but if @TheQuentincc is still interested I’ll take the 11€ offer for the dead stick + 15 ICs + pcb if I can find it
