    That's right, instead of 1x 5V and 1x 12V. Higher voltage makes my VGPU drop lower.

    Do you get 2.09Vgpu as a result of this mod alone, or is the card Vgpu modded the regular way too?

    No, it's modded in the normal way too. Both vgpu-mod and ocp-mod.

    It looks scary, those poor Vregs need to deal with a 140% voltage boost.
    For those of you about to post:

    Or 180% with 12V rail @ 14V... Still working like a champ.

    Edit: 11V worked just fine, 12,5V too... but 14V did the shit, bang :banana4: Blew one cap...

    sky: Got about 9MHz with the 12V line at 11V... From 669 to 678, it helped me reaching 39k..

    reject: Only the cap that got damaged from what I can see.

    moddolicous: Used a 1000 µF one rated for up to 16V now, the old was a 470 µF rated for 5V, no wonder why it didn't take the pressure...

    mod_evil: Wasn't that hard to fix. Using about 2,1V on the GPU and 2,25V on the RAM.

    Aphex_Tom_9: The same I thought the first time i powred the system on with this mod, but it lasted until 14V...

    since the 16v wouldnt last, you could try a 24v cap, but what type of cap is it. Thats not a normal electrolite is it?
