Tutorial: How to softmod to ANY VGPU you want without hardmods! (1.3~1.6v or more)

[Falkentyne]

the second step just returns "41" for all the values for me??? on a sapphire 4870. Is there anything i can do with that??

Try reading the thread?
Already answered. a few posts ago -.-
Do people read anything these days?

[jarman]

yes, i read it...but i dont quite understand, sorry.

i see u had no better clocks increasing voltage when the program returned 41 on the 4 commands?
is 65 hexadecimal for 41??? and what should be entered into the formula??

sorry if the questions seem a bit noobish....my knowledge lies more with cpu oc/watercooling than this sort of thing

Hehe, just thought the exact same thing.
The answer, in most cases, is unfortunately NO.
Most people today are comparable to RAM. Random Access Memory, which loses all its information if shut down for a second or two. An the bad thing is they (that is their brains, if there is something worth calling a brain) shut down repeatedly after very short periods of time.

On a side note and again on topic:

If you don't understand hex or binary and those "things", then don't even bother to try to modify your card, unless you want to brick it.
First you learn and then you use, not the other way round. It's the same thing with talking: First you think and then you talk. At least that's how it should be done.

i'll retract my previous comment and wont say any more than that.

Wow, you do have the ability to read and comprehend.

Already understood how to vmod your card?

firstly jarman do not retract anything.you are entitled to say what you want.

the replies to you are one of the underlying issues in this forum,ing knowitalls who like to pontificate to the greatness of their knowledge and thought processes,and coming down hard on those perceived to be less than them.

go to this forum where there
is a nice discussion about this process without any condescension

thanks jtf2, much appreciated. I will register on that forum this evening

Well, I updated to 9.1 Cat's yesterday and decided to try this again. Seems now that 840 core is stable for me in FEAR with 1.3125v. Before I'd get tons of VPU crashes for no reason within seconds, while it worked fine in Furmark for extended periods of time.
Now that this is working like it should for me, I'm curious. How high should I safely be able to take the volts on this with just a stock cooler? Anyone have a rough value?

Also, for jarman; For me 15 is the idle voltage, 17 is the 3dload voltage, and 18 is the voltage it uses for 3dload after a VPU crash. Adjust accordingly.

if i recall correctly on that card it is 1.37 volts and then ovp kicks in

[drifter]

is there a way to bypass OCP? anyone knows?

[Soultaker52]

Wow, that's only like .1v increase over stock. Sorta low compared to when the GTX 200's OVP kicks in. Oh well, I guess I'll just see what I can get on the stock cooler then, play with it and see what heat it pumps out on the vregs. I don't really see much of a reason to get some aftermarket on there if OVP kicks in at 1.37v, unless the vregs are going over 100C with normal usage.

Thanks. Now off to play.

From what I know, it'll require a hardmod. Seeing as this is a softmod, that sorta defeats the purpose. If you want to go higher, you might as well just do the hardmod for the volts as well.

[NCspecV81]

Guys I just upped the volts and furmark even crashes at stock! =o)~ This is even with 100 percent fan speed on the jet turbines!

OVP...
Is never a problem with this mod because OVP trigger voltage is always higher than VID. Such a software voltage controll feature wouldn't make any sense if this wasn't the case, now would it?

For what card? And what makes you think OCP is a problem?

I hope the "purpose" is not what I think it is...

[gurusan]

Does anyone know if those Xpertvision "sonic" cards use the same controller?

[largon]

gurusan,
It's quite safe to say they don't.
PALiT (aka. Xpertvision, Gainward) Sonic cards are all in-house custom boards.

[gurusan]

Ok thanks for the info.

[8800's@over]

This softmod works for GTX 260 55nm ?

OVP...
For what card? And what makes you think OCP is a problem?

for 280 gtx. The reason i think there is a problem with ocp is because current does not go up after a certain V setting (like some users have reported).
so any1 got a linky to ocp hardmod?

[largon]

Current not going up is not a sign of OCP. It means the VID didn't get changed.
When OCP triggers the only sign you will get is an instant reboot.

[fornowagain]

Any idea what going on here then?

I know for sure is the vcore measured from the back of the card never exceeds 1.35v volts no matter what value I use. This is a trace from 'in game' loads compared to resting loads at different voltages. It doesn't pull any more current in 3d 1.52v than 3d 1.35v. And were it moves to 1.52v in resting mode the current is well under even the 1.26v stock load current. So no evidence OCP. And OVP should always be above the set VID.



1.06v (2d,3d low registers) to 1.55v gives ~1.35v. Upto 1.35v its very close to the DMM values in 0.0125v steps. But something is limiting it, voltage increase is linear till it hits the wall.

[drifter]

^^^^^ i was talking about the very same thing. so what is it if not ocp?

[fornowagain]

I don't see current limiting, just the VID won't go over 48(h), 49(1.36v) no increase. And I've polled what I think is register 13 to indicate overvoltage and that doesn't change bits either. Could do with a data sheet for the registers.

Where is the logic in triggering OVP in this situation? As far as I understand VT1165 principles, the sense of OVP is preventing output voltage from going beyond Vnominal + OVP (hardwired and defined with configuration resistors). Vnominal is output nominal voltage, i.e. the voltage VRM is expecting to see on output, this is the value you are seeing at RT's hardware monitoring graphs and this is the value you're programming into VRM. So for example if VRM is programmed to give 1.4V on output and resistors define OVP of 200mV, OVP condition will be triggered when real output voltage goes beyond 1.6V. This makes sense for hardware voltage mods, when you change the voltage without altering programmed VRM's nominal voltage. In this case you change voltage by altering nominal voltage yourself. And VT1165 supports much higher voltages than 1.37.
It sounds more like and OCP for me. Maximum current for each VRM phase is also hardwired with configuration resistors.
I've already posted it in other thread: you can "ask" VT1165 to report OCP/OVP conditions by reading its register 13. Bits 0 and 1 are OCP/OVP states. Take a note that these bits are read-only status bits, you cannot change them.

[jcool]

No use going higher than 1,36V anyway if I you can't get even 1 Mhz more out of your card than at stock voltage, now is it...

[fornowagain]

Mine does fine, need some more for 860+
