700mhz wall on HD4850 is smashed.

[gurusan]

For anyone who is interesed, I have modded the 4850 MSI bios....not only have I raised clocks and voltage under load, but I have improved on the powerplay feature as well as the fanspeeds. IMO this is how it should have been shipped from the factory...it is a bit loud while gaming and such but this way the cooler is actually effective!:

2d clocks
.98vGPU, 160core/500mem

3d clocks
1.20vGPU, 720core/1100mem

The fan will only go down to around 25% in idle and 2d clocks, but it's pretty much inaudible and during 3d clocks should keep it under 70c full load, more like mid-low 60s.


All the reference 4850s should be able to do this, but if you are getting crashes then I can make you up a slightly less aggressive profile, or you can edit it yourself with the RBE tool. I recommend stress testing with rthdribl and some Crysis benches.

so i installed rthdribl and ran it, changed the multisampling to 16x but every 30 seconds the screen starts skipping and I get 2fps, it also did this with 4x multisampling.

is there a setting that I did not do? or does that mean the card is not stable?

Thanks for that BIOS Gurusan. It works a treat for me Its good to actually hear the fan doing some work under full load!

I think the fan is doing a bit to much work if ya know what i mean
I'm gonna try and pick up an S1 over the weekend.

And did the 2d profile work for you? or am i alone in that issue?
I've reinstalled so many drivers today and yesterday I'm thinking of just doing a fresh windows install :/ I might have really jerked with some crap in the registry. it'd be nice to have an official driver actually.

2d is working for me. GPUz always shows me the 3d clocks in the main window while the 2d clocks are shown correctly on the sensors tab. My idle temps are a lot better too.

2D isn't working on any of the BIOS for me. hmmmm, is there a power saving mode you have to enable somewhere that i'm missing?
I've tried what seems to be all the drivers, and tried them more than once, but it just wont kick in to 2D mode no mater what...

in the sensor tab? did you check it, the front "page" will show the 3-d clocks but the sensor tab should show real time clocks.

Yeah even the sensor tab is showing the 3D clocks. And the temps reflect it, so I know it's not just a program bug. I'm at a loss.

Gonna try on more driver reinstall.

thats the intended behaviour. first page will show the 3d performance clocks and sensors will show realtime clocks

Out of curiousty... how well do all of your overclocked cards hold up when running FurMark (http://www.ozone3d.net/benchmarks/fur/). I'm able to run 700/1000 at 1920x1200, with the fan cranked up a bit, in rthdribl (x16 multisample), 3DMark and games. However, running FurMark will bring my card to a halt.

Thanks for the clarification W1zzard. And 2 thumbs up for all your work for the community.
