How to vmod this newbie? Galaxy 7300GT DDR3

[Lanc]

Hi! I have the Galaxy 7300GT 128mb ddr3 1.4ns PCI-E

Looking at the pics, I could not find anyone with the same PCB, so I'm kinda afraid to vmod it without some pro advice.
Here are the pics:
The area around the IC:

As I have no multimeter here, I really would like to be sure before I do something.

This is the same PCB as you can see in the other photos. You must pencil r451.

At stock voltages I can get my 7300gt at 550/890. If I add voltage to the gpu I get 650MHz on 1.43V but then I can't get mem over 790 to be stable :?
I bumped the memory voltage a tad, but didn't seem to do anything.

We need VDDQ mod for this card. I think the VDDQ is to low to handle vgpu and vmem mod.
[quote]3. DO NOT volt-mod the memory with the above resistor 437 .. I think it does exactly the opposite: it decreases memory OC. Wipe any pencil trails from it with acetone or technic alcohol.[/quote]
It increase memory oc but only if you don't make vGPU mod. Becouse if you make boths mods card aren't stable.

I have different PCB than yours all.
Take a look.




Can someone help me how to V-MOD it??
With stock voltage I can clock it from 400/900 to 670/1300.
My memories are 2.0ns, but DDR3 and I've expected from them 1400-1500.

Temperatures are ok, on 670/1300 37C idle, 55C stress.

The 2 chips labeled U14 and U15 on the PCB are your voltage regulators. What does it say on them?

Ty for answer, they both have symbol: APW7063 MI2GT
