MSI GTX570 TFIII PE hardmod - Page 3

*i didnt trace to pin on mine.. mods were already confirmed 

 As for testing the OCP mods.. use pencil first.. you can monitor OCP % in GPU-Z.. you may see some change when you pencil hard. Other than that.. you should see no other affects. So if GPU start acting funny or refuse to start.. clean pencil off and restart. Basically.. your testing with pencil to confirm that your not modding something other than OCP.

 nice work man. If you would be so kind as to link these pics in a new post, over in the vmod essentials thread... we can get these added to the library 

*From testing my mod'd 6950 [same power circuitry we are talking about here though..]

There is a small gain in voltage under load, of ~ +.015v after OCP mod.. so setting 1.35v = ~1.377v real under load.

If you here a lot of squeal under load, measure at the PCI-E inputs to make sure your +12v supply is not dipping too much [should stay within +/- .15v while under load and transition]. My TX650 was not sufficient once voltage approached 1.4v with core +1ghz.

 Have fun! Post some results too.. I would like to see how it responds 

game at high res.. or use Extreme mode on Vantage and run only GPU tests  This will load memory, VRM's and push shaders & core with good res+AA&AF

You will be fine with that particular PSU.. its very strong and capable of much more.. you can see how a tenth of a volt is already munching a LOT more current from your PSU though  . Above 12v input is good.. just know the lower it is the more pronounced squeal will be from the mosfet/inductor stages when pushing high OC and GPUv. Im not sure at what point it starts limiting your output.. but most electronics like a small buffer to help deal with transitional load.

*cant wait to see some clocks !!
