    Default I Seem to have Hit the Slightly Mythical 222 BCLK Wall...

    Well, as the title says, I cannot get any more than 222 BCLK. I'm trying to get a 4.7GHz SuperPi 1M run, but the board will not let me get in. The processor (a D0) and the entire board is under water as well, so temperatures are not an issue at all.

    Anyways, I know it's not the chip because lowering the multi to 20 (223 BCLK @ 4.46GHz, a stable clock on my board) will not boot. I've run my memory as high as 1900MHz on 1.68V and 8-9-9-24 timings, so it isn't the memory either.

    I tried upping the PCIe frequency from the 100 I had it set at, but if I move it even 1MHz, it will not boot. Even with a previously bootable setting.

    It seems this board doesn't want me to get around this BLCK hole.

    Also, a slightly random question, has anyone else noticed the TERRIBLE VDroop on this board? I dial in 1.55V in the BIOS, and under load it's around 1.52V, with LLC on. Is there a pencil mod out there or any easy Vdroop mod to help out with this?

    The point of it being a BCLK wall is that you can't get past it by conventional means. You can by all means search for the hard mod to get higher BCLK speeds, but do so at your own risk.

    0.03V of Drop/Droop is not terrible. If you're truly getting 1.52V at full load, when you've set 1.55V in the BIOS then you're doing extremely well. VDrop and VDroop both play a part in the voltage you see in CPU-Z. Also, this can't be deemed 100% accurate, software voltages never are. Use a multi meter to check. Remember that any drop/droop on the board will worsen with higher voltages.

    Zero Vdrop (difference between BIOS set voltage and idle voltage) and VDroop (diff between idle and load voltages) is not going to help you out at all, not with such a minuscule amount of drop/droop (don't know which as you never stated idle Vcore). At high VCores, like 1.7V+ (under extreme cooling) this drop/droop may get a little worse and start to be a factor, but for you, 0.03V is insignificant.

    This was set with 1.5625V in BIOS, the voltage in the picture is idle, and it dropped to 1.49V under load.

    Is there a hardmod for this board that I could use with my chipset being under water?

    I guess I'm going to have to practice some soldering!

    Thanks much for the links.

    So do I PM hicookie for the BCLK mod? Every seems to be saying it's there, but I must be an idiot. Also, I'm using the most recent Beta BIOS, does this have the PCI-E option that everyone is talking about in that?

    Ahah... it seems to have appeared in the later pages of the thread.

    Mannnn. I gotta take all this WC stuff out now! Dang! My HAF is FULL.

    Read the thread, the mod image is posted a few times towards the end, so no need to PM Hicookie really.

    PCIE Option in the F*x BIOS versions is only needed if you want to set PCIE in the BIOS, otherwise you can use ANY BIOS and set from windows with SetFSB. This is what I use.

    Ahh, see you found the mod images finally.

    VERY SMALL, do not attempt if you are unsure of your skills!!! Practice on another dead devices PCB if you can, it is harder than it looks for sure and those are very tine and easy to loose so be sure you are working in a clear area where you can see things if you drop it or it flies on you :)

    I'll be doing it in my universities EE lab. My $7 solder gun probably won't cut it. This way I'll be able to solder it in one fell swoop. I'll probably do the other mods while I'm at it.

    I need to get a Dice pot badly! But I don't have enough cash.

    I might sell my F@H rig to see if I can fund one...

    You will need a good gun, with a small point and low heat.

    Yup! I have access to all that and more.

    Also, some extra resistors in case I lose it or do anything stupid.

    It seems there's interest in the rig. I may be getting the pot sooner than later.

    Nice to hear, it is 0402 SMD resistor 1K Ohm... Just in case you need a new one :)

    Good luck with the Dry Ice, I just got into it a few months ago myself. Very fun to do!
