Default I've modded my 3850 agp bios

Hello everyone,

Yesterday I've decited to play around a little with my bios settings, which resulted in a nice performance gaming boost Below are my tuned bios settings. My card boots at 725/900. 3d speeds are set at 735/950 The ATI control panel had a limit of 720 Mhz for the core speed. I've downloaded the bios of the 3850 oc'ed edition and used that signature file to raise my overclocking headroom. I carefully tested my card at 720/950 first and it seemed to be performing well, so I felt comfortable using that signature file. Please note it's risky to just use a signature file of a faster card, because those clocks usually exceed the cards capability. Also you will be using a wrong device id in that case, so the driver won't detect your videocard. I've also raised the vgpu a little from 1.214v to 1.254v in 3d speeds. I was able to select that higher voltage in my bios. I've also increased the FAN percentage to make sure the gpu gets enough cooling.





I've tried a 3dmark03 run without pushing my cpu and ram too hard:

A very cool thing is that NFS Shift is now playable full screen 1900x1050 with AAx4 and AFx16 settings It's just a whole lot smoother. Before around stock speeds that was unbearable Tweaking my Windows installation by disabling unneeded services and start-up programs have also contributed to this.

Nice, I did this with my 5750, too bad the newer drivers screwed it up.

How come, did the new drivers not recognize your videocard anymore? When not using a hash (signature) then this happens to me as well. The trick is to find a modified or an overclocked signature file..

Nice work on that overclock GFreeman! I admit I haven't used that BIOS editor before, but damn, does it look thorough. I might have to look for an NVIDIA counterpart so that I can force the card to run at 60% fan speed all the time (summer is here, don't need a 60~80°C GPU adding to the heat!).

NiBiTor.v6.02 supported changing fan speed in 3d mode as well. Although I have to agree RBE is more advanced. I really like you can change the fan speed when the card reaches a certain temperature instead of just fixing your fan to run at the certain percentage in 3d mode all the time You can do that with NiBiTor as well I believe, although the user friendliness is not as great.. You probably have to be some guru to do this LOL!

Well this tutorial I found might help you, but it does require quite a lot of reading.. I'd say K.I.S.S. (Keep It Simple Stupid) haha! But oh well....

I've used this tool before it works for not EVGA nVidia cards as well. You can set a certain fan speed after you booted into Windows. Can be handy if you need a quick solution http://www.evga.com/precision/

I'll check this out. The 5850 in my laptop is always very hot. Sometimes during long gaming sessions, the keys actually get so hot I can't keep my fingers on them. I wonder if I might be able to do something to help with this.

No it read the card, it just locked it. No matter what I did it was lock at stock 700/1150 unless I did the ATT workaround and changed it to 870/1370 but then it was locked there.

Also Rob, NiBiTor is great. I used it to up both my cards vcore from 1.17 to 1.18 and OC them to the max. Once I put them on water I also zeroed out the fan speed and upped the OC as far as possible.

Well I've just ordered a Zalman VF1000-LED VGA cooler for my ati 3850 agp videocard I've noticed that that card runs a little hot after softmodding the vgpu a little higher. It sometimes reaches 90 degrees and I have seen 105 degrees max on a hot day. Before that the card reached about 82-85 degrees max, which still is quite a lot. I think my cooling is going to improved enough after this modification After I'm gonna search for some more overclocking headroom

Mine are under water, they now hit a max of about 42C. go OC!!! If temps hit about 60c or so they start crashing due to the shaders being too hot.

Well here's 30k on FM03.. Running on Windows 7 and I haven't got overclocking ram in here.. This ram doesn't like overclocking so much so it could be better. Card running on 735/950. CPU at 2907 Mhz, ram at 207Mhz.. 2,5-3-3-6 2t..

Well.. here's well beyond 30k with the cpu at 2931Mhz just a little higher.. That's about the ram will take I guess.. I'm fiddling around a little that's always fun!

Well this is my highest score so far. I tried popping to the DDR333 memory divider, but that meant I couldn't get my cpu that high the ram just wouldn't cope. I'm happy with this 2gb DDR ram, but it's Kingston so not the best overclocking stuff.. I used to have a 1gig kit with Windows XP. I remember getting the ram way higher. The board cuts out around 270htt.. The A8v won't do much more. I have been able to do 272-273 once.. lol! Around there the PCI lock sometimes stops working.

Well, here is 30,5k I was at 268htt with 210 Mhz on the ram or so.. 2,5-3-3-7 1t timings. http://3dmark.com/3dm03/6422748

I didn't quite expect my puppy to do this lol! I've tried some more bios modding and set the 3d clocks at 750/950 and it actually ran the clocks no sweat at 1.254v vgpu.. I wonder what more this card can do actually. But I gotta improve cooling for that matter. It does have an effect though on my load wattage LOL! Stock this thing comes at 669/829 so I'm pleased with it so far

Here's the new score! Same settings on the cpu and ram as the last bench. Except the card tuned up a bit. http://3dmark.com/3dm03/6422763

That's not it yet. Here's 760/1000 That's something else compared to the overclocking lock at 725/950 by the calalyst driver



Here's well beyond 31k
