    Hard to tell if it's good or not yet, but 4960X @ 4.7GHz benchable @ 1.35v. Watercooled.

    Also have some other cpu's.

     

    Summary:

     

    i7 4960X(ES, QF7Z) @ 4.7GHz cinebench @ 1.35v

    Batch: 3321A576

     

    i7 4960X(ES, QF7Z) @ 4.5GHz cinebench @ 1.4v

    Batch: 3320A573

     

    i7 4930K(ES) @ 4.6GHz cinebench @ 1.4v

    Batch: 3320A829

    Just tested my friend's cpu's. The L310B491 was not worth it, but the other one did 4.9GHz at 1.35v. It would run up to 5.4GHz at 1.4v superpi 1m with ss cooling. No screenshot of that. 5500 is definitly possible with more voltage, but I didn't have the right os to test any further at that point and only limited time.

    HD 7970 clocks problem

    in General hardware discussion

    My solution for now, even though it's not the best, is to use this tool to at least be able to run a decent overclock. Got my card running 1100/1700. Not much more is in it because it doesn't have voltage control. When you use it, don't forget to use this command: atiflash -f -p 0 bios.rom. If you don't use -f the flash will not work because it doesn't have a checksum.

    HD 7970 clocks problem

    Hey guys,

     

    I recently got me some HD 7970's from XFX.

    Last night I tried to overclock with them and noticed that everytime I raise the clocks, the system hangs as soon as it starts a benchmark, so I decided today to pick one card out and see what it's capable of.

     

    Here's what I figured out:

    Stock clocks are 925/1375, I just flashed a custom bios with 1050/1500 clocks(not GHz bios).

    At these clocks it still runs fine, but when I up the core to 1060MHz for example I already got enormous artifacts, even though it's only 10MHz more. I modded the bios again with 1075/1500 clocks and it ran fine...

     

    What is going on here? Why can't I set a normal overclock without it crashing or artifacting and when I flash the clocks there's no problem?

    Here's some info about the -4 command.

     

    OVERRIDE SWITCH -4

    nvflash --index=1 -4 -5 -6 BIOS.ROM (enter) (BIOS.ROM is example name)

    There is an override switch for force flashing mismatched sub-vendor or hardware ID's (often required for flashing a BIOS from a different vendor);

    This command will flash your GPU with the new BIOS that you selected by typing the name of the BIOS.
