MSI R5850 Twin Frozr II voltage issue

[chew*]

845/1375 no voltage added

900/1375 @ 1175mV 06/vantage/gaming stable

950/1375 @ 1240mV 06/vantage stable no real gaming tested atm

975/1375 @ 1265mV semi benchable but far from stable






may I add that all temps displayed are always on the cold side. So the cooler does work nicely - or the displayed temps are irrelevant. I'd love if you'd let me know whether the VRM cooling helps

well paste application or VRM cooling did the trick however, card apparently blew up.

From what i can see it's stuck in 2d voltage mode, artifacts when it boots and 3d voltage will not apply ( measured).

Job well done

I am considering setting mine on fire and dance in a circle around it, too








Jokes aside, try cleaning everything up and redo with ceramique. Maybe worths a try...

nah triple verified it, it's toast temps are in line, I think msi capped it at 1.3v for a reason.

I could hear it screaming through gt3 and 4 at 975.


On a side note drop your ram down to stock and see what your core does then, thisnk this card is a candidate for vddci.

Mine screams too - all the way from 1.2V and upwards, in the heavy scenes. But I am not a man of merci Let those military-grade-bla-bla coils scream as much as they like

Sorry to hear about your card though It seems like, this non reference design is a lot worse that the reference. I think that's a world's first

I might give the vid mode a try myself later this week, I'll update the thread too. Thanks for everything *chew

Just tested my other card, duplicated the circumstances the first card died at......this one is fine, that card must have just been a freak thing.

To bad that was the better card as ram goes. Both of mine top out 975 core..... well when one isn't blowing up

It might took me a month or so, but boy, do I have news for you?

The bad news: I didn't manage to go over 980 core no matter voltage, vrm cooling and a swifteck waterblock on the core. I tried fiddling with the OCP resistance but I didn't see a noticeable improvement.

The good new: The fb mod worked like a charm. I kinda thing that the fb mod instructed voltages were more stable & spike free, compared to those applied by the Afterburner. At least my fluke said so

The best news: I reattached the original OCP resistor and settled down to stock clocks @ stock voltage. I did some gaming during Christmas holidays, everything was fine. After a week or so, the card died! Yep, it's dead I was killing some Italians in the Mafia and a minute later it black screened and never revived. It doesn't even recognize it as a second card. No blind flash either. And I don't even care







So thanks for the time, I think I won't miss that card at all. It's been a mediocre card for me. I attach the bios that msi provided me for future reference, but I suspect it's the same bios my card came with. Chew* thanks for the time mate, you are the man
