Sooo I decided to mess around with the Galax 666W VBios for the 4090 last night.

Backed up my current one and then flashed.

I was happily surprised that I was able to pull that much power through my 3-pin to 12VHPWR cable.

Though I would admit it didn't do anything other than make the card run hotter than it was before. Maybe 1-2% increase in performance for 25%+ power increase...

On my stock VBios, I would occasionally see 400W and my core clock would be between 2950-3025Mhz full boost... With the Galax VBios I could get get up to 3075-3125Mhz... but it was pulling 600W-650W.

The temperatures were drastically different.... my 10C delta between core and hotspot (typically 55C-65C, respectively) shot up to a 20C delta (75C-95C) when using the Galax VBios....

Yeah, it definitely isn't worth it, and I put my stock VBios back in place. I also watched a couple YouTube videos for the giggles to compare.

Please.... my fellow 4090 owners.... Just leave it alone, it isn't worth the extra heat and wear on the card. Use the Nvidia/MSI OC Scanner and enjoy...

Well yeah, Galax GPUs are usually binned specifically for their cards higher tier. I'd expect no less from it :)

Yeah i found 2 of your files in the collection 480W is your max, pg 139 sku 330 is the board part number, you can always try the liquid cooled msi card bios in the 4090 range which has like a max of 520W.

And thank you for being logical about this, many do a flash and then wonder why their fans run faster or the card starts throttling to try and not go super nova

I flashed mine back after playing with the galax bios, even ran the release 600w bios instead of the patched (post release updated) bios for my card (530w) for awhile. just wasnt worth tbh. now im sitting on post release vbios; just wasnt worth it.

Yea there is a point with processors that you need many double digit % in power to get single digit boosts.

10 FPS for +60% wattage. This overclocking is not worth it anymore no matter the brand, the make, anything. Enjoy your mighty GPU!
