Reference GTX295 Volt Mods

[Kabauterman]

Well I see the CBGPCS has the OVP mod as he is benching at 825 core... wanna share buddy?

Stelaras has it too so guys please share!!!

or do they use Water-Cooling?

€: they use only Water cooling, no OVP mod

OVP mod is not needed anymore.
Use this instead.

max Voltage... 1350mV

sorry but OVP is needed!!!

[largon]

max Voltage... 1350mV

Err??
There's no such max voltage.
People have gotten >1.6V via this soft VID mod.

Hardware OVP mod is not going to happen...

ok sorry I only read the link to EVGAs tool... there you can only set 1,35 V
it suxs that you must run it on every restart!

Well, you're going to launch RivaTuner anyways, and since you can schedule the command to be automatic when RT launches you don't have to manually do it every time.

i wanna know who has the cojones to buy this card and then try this out! what happens if it dosent work!???

[TheKarmakazi]

It works

Hello .

I tried this soft Vmod with my asus gtx295 and it works very well .

Before i could not pass 700 mhz gpu with defaut voltage ( 1.04 volt ) and now with 1.17 volt i can bench at 740 gpu !!

But i have got something strange : the voltage is the same at idle and load , even without vmod !

So , do you noted the same thing with your gtx295 ?

unwinder says in the thread how to do it in startup as well

who'll be the first to try 1.6v now on LN2 hheheh

GTX 295 will change only in 0,005 V between idle and load, only Voltmeter can mesure this

@dinos: my card is broken :-( so I must look for a new one

Ouch sorry to hear about the card What happened?

[Kabauterman]

:-(

don't know why, but card shows failures in 3D and freezes sometimes...

[dinos22]

oh man that's no good

I have still yet to bench my card (this week sometime) and I will confirm this afterwards but.... From a couple posts it appears that OCP (which is what we are triggering with 1.3v here not OVP) it NOT disabled with the VT1165 softmod.

Unwinder says this:

Hmmm... That's a status of 100% healthy VT1165 VRM. The status bits include:

- VRM reports that its voltage output is enabled (VRM can be shut down due to fault condition on some of slave phase chips, e..g. due to critical overheating)
- VRM reports that output voltage is in "power good" state (i.e. the difference between nominal and real output voltage is inside pre-defined "power good" range, e.g. 100mV)
- VRM reports that there are no input undervoltage and overvoltage conditions
- VRM reports that thera are no output overcurrent and overvoltage protection conditions

According to these state bits, there is desired voltage on the VRM output. Looks like there is some other circuit on your PCB limiting the voltage behind VRM output.

Now one of the mods vince had done to his cards was "Power good" mod. I think this maybe the key to defeating the OCP on these?

little nice tool from my german collegues of Awardfabrik.de
