Can you damage a GPU by increasing Bclk to 100.1?

I increased the base clock in my BIOS from 100 to 100.1. I've read that increasing the base clock can damage anything in the PCI-E slots. Could this small adjustment damage the GPU?

Not really. I mean I really, really doubt it. I've run with 102 BCLK before with the 2600k that I owned previously.

I should add, it is extremely difficult to make BCLK overclocking work. I can't even do 100.1 on my current chip. That has nothing to do with my GPUs, though.

No.

I've been running my entire system overclocked since may 12th 2012 and nothing has died. You need to manually control your voltages or adding to BLCK when on auto could damage stuff on the mobo, but not in the slots. (Specifically vccsa, vccio, and CPU pll)

I run a p8z77-ws with 107blck, a 3770 @ 4.38GHz w/1.22v, and 1600MHz DDR3 10-10-10-27 2t at 1712MHz 9-9-9-27 1t using a 100:133 divider. My 580GTX Lightning Xtreme 3GB in SLI are also overclocked to 940/1880/2400.

I had to fine tune voltages to get it stable, but after almost a year I haven't had a WHEA error, save when I downloaded the latest bios and had to re-tune.

The only thing that will cause damage is too many volts and/or too much heat. BLCK is just your FSB frequency, which everything (memory, pcie) runs through to hit the processor. Too much frequency and not enough volts = instability. Too many volts = too much heat = CPU death, since the memory controller is integrated and you can toast the northbridge on the board too.

Experienced overclockers who test for heat and instability at each step should be fine. Newbies? Not so much. Too many volts and a quick degradation and death is around the corner.

I think BCLK OC on 1155 is so limited, that is impossible to get to a point where the PCIE clock would be problematic for the VGA...

with lga 775 I even tested PCIE 120+ without problems with the VGA.

I couldn't get stable above 107, even with no OC on the RAM, CPU or SLi.
