What are you running crossfire...
This is taken from a 6950 on the 6950 overclocking thread...
What card do you have and what settings and resolution are you running?
Yeah sorry but I don't believe you...
I know the resolution your running is a little lower but no way, your claiming faster than 6950 speeds with only a slight lower resolution...
I would like to see a screeny...
Actually I found is that with moderate level of tessellation (not normal level), 1920x1080, 4xAA, 16xAF, besides the low frame rate dipping to around 24fps in the very beginning of Heaven Bench (due the heavy amount of tessellation I think), for the rest of the bench the overclock 5850 would pretty much remain at around 30fps and above.
Ah sorry...I did read your post, but I can't really recall my bios setting at the top of my head. You should have a look at the following...this is what I used as a base reference when I first attempting my overclock:hmm looks like marine-rx179 has either not seen my post or is ignoring it/not bothering to answer, guess I'll go talk to myself as usual

Considering you are only on 1680x1050 res, I think it might be possible for you to get reasonable frame rate using moderate tessellation, 4xAA, 16xAF. Your 5850 would probably struggle a bit at stock speed, but I think if you work at overclocking the card, it should give you good enough result on smooth enough frame rate.
Edited:
I ran the Heaven Bench at 1680x1050 dx11, 4xAA, 16xAF, moderate tessellation with my two stable overclock profiles (instead using the 1000core/1300memory). The settings are core900MHz/memory1200MHz/voltage1.240v and core975MHz/memory1100MHz/voltage1.265v, and here is the result:
From my previous bench, I found that by turn the tessellation from moderate to disable, it would give around 10fps high in frame rate (and that was at 1920 res, so for 1680 res it might give even more frame rate than that). So basically if you can overclock your 5850, you should be able to run the bench at 1680x1050 dx11, 4xAA, 16xAF, tessellation (disabled) with minimum frame rate at around 35fps.
But I have to say...with minimum frame rate at close to 25fps with moderate tessellation is not bad result at all.
Have you "enabled the unofficial overclock" yet?
Just curious...have you tried higher voltage for overclock, or are you having the same problem as Monster ninja on upping the voltage?I'm trying the max 775/1125 overclock with Unofficial Overclocking disabled at @1.095V.
The card gives me serious headaches refusing to overclock at all
Has anyone tried contacting MSI about a more updated BIOS? They could have at least get rid of the limits.
The way I see it is that you can't really compare the Twin FrozR to you reference 5850, as while they both bare the name "5850", I think they are two different breed of animals due to different design.There's something seriously wrong with these cards, advertised as great overclocks they fail to deliver with their low overclocks requiring very high voltages. Take yours as an example, my reference Sapphire 5850 (average, mind you, see the old overclocking thread where some get far better results than me with stock cooling) does 835MHz on core and 1200MHz on memory at its stock 1.087V. Your MSI card requires 15% more volts to do the same! I could bench at 1GHz on core with your voltages
