GTX285 VGPU and OCP mod

Here is the VGPU mod for nvidia GTX285 to start with, I will update the thread as soon as I have the OCP mod image done.

I will also post some more info from our Tri-SLI benchmarking at CeBIT 2009.

! IMPORTANT INFORMATION !
These mods have been tested, BUT I take no responsibility for how you use
the mods and what happens to the card. Make sure the cooling is sufficient etc.
The soldering order is crucial, make sure it's done exactly as the images show.


Mod overview:

This is how it looks when soldered to the card.


We ran 1.4V+ and no sign of OVP.

OCP will trig at some point and here is the mod for that:

Please post at what frequencies it triggers for you with what type of cooling.

I will probably be doing this mod for a friends 285 if the results are good from Crotale.

If he really can do 900 mhz on the core, I may have to do this on my card too.

I think 900 core would be a stretch with air or water. With LN2 it's another story. We were doing some quick single card tests at 1100/2200+ core/shader with around 1.4V, so the achitecture is capable of it.

Is this some sort of voltage divider?

Also nice Vantage scores What kinda clocks were you guys running for those?

Exactly. I guess the 0 ohm resistor is there to simplify routing. Lucky for us

Around 1000/2000/1400 core/shader/mem.

Thanks crotale........

I didn't have much time to start seaking for the mods (except the OCP triggering) and you've helped me with the VCore mod......

1026/2267/1404 with 1.4VCore.....1.44V for 1058 core and 1.5V for over that at -102*C
I haven't done the Vdimm mod yet....

Nice runs

The shader was slightly more stubborn on the card we tried.
1120/2200 has worked, but we had to lower the memory for those speeds.

vmem rises slightly with vgpu and at some point we need to lower the mem clocks.

*Updated the first thread with OCP*

Have you seen George's mem clocks ?
He's done GDDR3-1500 @ 3D Mark2001SE ( and without any Vmods for the memory like he said ) jeez.
I tested a GTX 285 yesterday on LN2, and only managed to get it up to 1040/2106 ( GPU/SPs ) at -105C approx.
About 1.45Vgpu

Some of these cards can hit 1500+ mem easily. Mine has no issues at those mem speeds, others seem to struggle or artifact though.

Please report voltages, frequencies and cooling so we get some references.

Don't look at the low score....It's because by old trusty PATA HD has failed during benching and I used a SATA one with only 120MHz PCI-E or the score whould have been 91k++ ...

GPU = 1.41Volts
Rams = default Voltage (I did't have the time nor the willing to mod it)
-102*C

if turn down to 1.22v everything fine.
on water temp not an issue around 45-50 C only.
would OCP help this ..?
wat value to turn OCP vr ? how to indicate ?
if over turned will fry my card .?

Solid color can be OCP.
Try just soldering in a 100k VR as the OCP mod describes and see if it helps.

ya it's OCP .
after added OCP mod no more solid hang screen.
only 1.4vgpu ,check temp at the back of card power phase area lotsa heat.bout 85c on FURmark
reduce to 1.35 for 24/7.
thkz man you're great.

What sort of clocks have you been able to get with the mod?

How is the card cooled?

Well, then I guess it's my bad luck once again.
2 out 2 cards failed to hit anything higher than 1378 without artifacting, and would crash nearly instantly at anything over 1400.

well believe it or not i had to ocp mod my unmodded 285 ftw/stock cooling

again thanks for the ocp mod crotale

air/even water cooling ocp mod is a must


edit: if you guys want higher mem.. ocp mod will take care of that too

ive gained 100mhz mem @ heavy load

you want lower temps? ocp mod will do that too


edit2: ive never been able to clock my ftw @ 1512 which would cause blank/black screens

here i am @ 1548 mem clock @ heavy load thanks to the ocp mod

overall 150+mhz mem gain @ heavy load @ stock air cooler

once again thanks crotale for the mod

Hey Mike, yes they were

Speaking of which, thanks for your support. The Dominators and the HX1000 served us well
