***The Official MSI 5850 Twin FrozeR Thread***

[Marine-RX179]

I am ****in tired of tryin and failing to overclock this stupid card
it stays stable at 775/1125 ( oc via ccc )
So today i decided to take it to 5870 clocks
after editing afterburner cfg my voltage is shown as 1164 aleady
so i lowered it to 1150 and set clocks to 850 and mem to 1200
i use Furmark to test stability
It appeared stable for few minutes and then got artifacts grr
also at one point it appeared stable at 860/1175 @ 1139 volts
but again after 20 minutes got artifacts
what the **** am i supposed to do now ?
please some one tell me the proper way to over clock
some hidden techniques or whatever
i want it stable atleast at 5870 stock clocks ( 850/1200 )

HELP!!!

Voltage too low for your targeted clock speed, also as far from what we found from out overclocking experience on this card, dx11 games don't like memory clock at over 1100MHz, so may be 850MHz/1100MHz is a more realistic target.

I can overclock my card to 975MHz/1100MHz, but that require 1.275v. Even my 835MHz/1100MHz overclock require 1.170v. I would suggest you try taking the voltage to 1.200v and test your targeted overclock speed first, and if it is stable, THEN work your way down on the voltage...until you find the minimum voltage necessary to keep the overclock stable.

I would prefer max stable overclocks as that is what I am using for comparison.

Well, it's kinda difficult to have a defined max stable overclock, consider some games are harder to get stabled on than the others.

I overclocked a friend's 6850 to 850MHz/1200MHz on stock voltage stable on Heaven Benchmark, but it will crash in BFBC2...dropped the core clock to 835MHz seem to have solved the problem though.

May be BFBC2 is just tougher on overclock stability for graphic card than most other games...

My 5850's crash loads even on stock settings, its pretty frustrating

You sure it is not driver issue rather than hardware?

Also, crossfire is not exactly 100% problem free (particular in the crossfire driver department)...have you tried the cards one at a time?

Guys, can you confirm for me if your MSI 5850 Twin FrozR comes with a Crossfire bridge? I'm only asking because I read someone said he got one with his MSI 5850 Twin FrozR, but I certainlly didn't...

Afterburner keeps resetting back to stock speeds (725 core/1000 memory) randomly and when I close Afterburner, anything I can do to stop this?

I think you just haven't saved the overclock profile? Also, why would you want to close Afterburner? It need to be running in the background for controling the fanspeed anyway.
