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 :rofl:

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








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 :D Let those military-grade-bla-bla coils scream as much as they like :rofl:

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

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

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 :p:

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 :shrug:

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 :clap: 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 :wiggle:







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 :up:
