MSI 5850 - Voltage resetting?

[Baneat]

I've got an overclock running on my Twin Frozr II r5850, and it requires 1.25V to remain stable. Occasionally (probably 1-2 times an hour on average) it will stick its finger up and reset my voltage to 1.164, instantly crashing the system. Le fu? Is there some kind of mod I can do that means I can volt and OC without having to use this crappy software? it never ever works, sometimes it just resets your clocks to the stock ones for the lulz.

*may have identified the cause but I do not know enough about video cards, I have a separate thread for this theory currently*

Flash the bios with new oc and voltage settings.

Um...


How?

it requires 1.25V to remain stable.

At what settings?

The frozr line have a track record of being great at stock and selling on great oc potential. Altering bioses is a risky business with cards, I wouldnt do it (Sorry baneat that other phrasing was rude!)

Seriously said it once and will say it again...reference cards own on oc...

Non reference super mega hyper gold platinum diamond oc ninja stealth cool made from parts sourced from the lair of a dragon low volt mil spec cap cool frozr ect...they wouldnt need to say it if it worked.

1.25V to keep stability at 900MHz and 1250MHz, not as good as some people are getting their overclocks to, but I think that's more or less luck of the draw on the card you get. I hear tell of people getting 1GHz core stable from 1.2V, but I can't get 850 at that, meh.

"user such as yourself"

Clarify? I'm not new to flashing in general, I've flashed my 360 and wii before.

I never believed the stuff on the box in the first place, the grammar being slightly off or just a little weirdly phrase tuned me off quickly. It gets results on idle, but who cares about the GPU's temps at idle when it's dissipating the same heat energy?

on full load super-mega-ultra burning Kombustor mode it caps at 90 degs celsius, and playing Crysis 2 for any length of time caps at 70 celsius. numbers are something stupid like 35 celsius idle and 60 load on stock voltage.

Long and short, the cooler works, but is less effective the further up you go.

I'm still not following the line of what you were trying to tell me though

Look at my sig.

Cry out loud.

Reference cards are the way to go.

BTW, the voltage drop issue occurs because of the dodgy PowerPlay. Everyone experiences it sooner or later, you may try forcing 2D/3D profiles with the latest MSI Afterburner beta. Your temps are way too high for my liking too.

Sorry but I ran my 9800GT at 70 degrees since they released the card and never once was there anything resembling a problem with it.

How do I force the profile as you mentioned? and I know I don't get the best O/C from the voltage required but, I don't care tbh, the site says the card runs perfectly fine 24/7 at 1.25 volts, hence why I set it there.

P.S

"Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path"

OK I set it to "2" in the config, which should disable the clock-shifting I was noticing whenever it handled 2d. Let's see if that fixes it.

Gah disabling powerplay did nothing!

 

[Baneat]

Tried everything I could think of, explicitly disabling the powerplay, FORCING THE VOLTAGE TO BE K!!!! and it still shifts to 1.164V!

Is there some way to spoof this card into thinking it's made by someone else, and use their software to run the overclock with?

 

[Baneat]

Following Mr Krugga's excellent advice (Very polite user!) I reflashed the BIOS in a hope to eliminate the powerplay's fiddling with the voltages. It unlocked the clocks further but that's pretty much the only effect to me. If set above 1164mV it eventually crashes and reboots the card with 1164.. Very annoying

Tearing my hair out over this inexplicibale issue

Sorry, that was rude, no offence intended.

What I meant was that its risky and I wouldnt do it. Cant help on the issue though.

I don't understand what risk there is, if you put a bad BIOS in flash it back again?

Of course, having a BIOS that would fix the issue would be required.
