Need some help. Damn bad card for oc, can only reach 500mhz core and this for 3dmarks, in games with 500mhz freezes. Need this vmod to my sli test with 2 6600`s. The first card reaches 550mhz / 750 with no problem. :freak:

On the backside is a regulator "1575 p(or r)ffz"
1. 2,36v
2. 13,13v
3. 0,98v
4. 0v
5. 17,47v
6. 1,47v
7. 0v
8. 1,47v

C137 and C134 should have the Vgpu on it. See which MOSFET in the picture has your Vgpu.



From there track which IC the MOSFET run to.

The results from the 5 mosfets

C137 - 3,33v
C134 - (0?-)3,33v

The nearest is 1.26 V from one of the MOSFETs.

Sir would you mind if you measure the tabs on the MOSFETs too. Hope that it can facilitate help here.

Thanks.

6600pcie vmod? woohoo!

These? :confused5

[yantronic]

Yep. Shamino let's scan through them. This is making me go 1

Haha, A Math and Vmods don't go together.

Q3 and Q4 are my current suspects for regulation. See if pin 3 of Q3 and Q4 runs to the LM324 beside.

[yantronic]

Yellow points. See if they run to LM324's pin 1, 7, 8 or 14. The 1st pin is beside the indent.

Continuity can be tested with a multimeter set to measure resistance "ohms."

Q3 pin3 goes to pin11
Q4 pin3 goes to pin 9 then :confused5

[yantronic]

Haha I realy go 1 liao.

You got some weird values like 13.6V floating around the MOSFETs. Wow.

You based in Singapore?

No, north europe

Hello there. I am based in SG. There isn't much an amatuer OCer and noob like me can do to help but I am trying my best.

IIRC, a PC tends not to have anything above 12.6V, let alone 13.6

Measured again Q3 and it was 13,59/60v :shoot4:
