How much does the voltage fluxuate.... - Overclock.net

on an 8800GTS 512MB G92, how much "should" the voltage be fluxuating from idle to full load?

I just did a volt mod on both of my 8800GTS's, and after doing and testing the first one, booted it up solo and it was outstanding, the second one I just tossed into the system straight to SLI, and well performance is possibly less than the single now. especially HDR/SM3.0, in 3dmark06 parts of that flying ship test go down to 26FPS, but hten other parts of it are 140FPS, so its really confusing me.

I checked the voltages during full load on that shader/hdr test, (note: stock voltage, 1.17, after my vmod idle: 1.216) they were fluxuating between 1.25 and 1.27 on both cards......

And its not a heat issue, they idle at 40C, 46C full load.

well after taking out the first card and running only the second one, I found out that anything over 800mhz core on my second card and the driver stops responding. Why is this?

whatever the reason, I take it I'm now over-volting my cards seeing as they cant run faster than 800mhz due to the one being limited?
