AMD 7850 2GB 2D Clock Issue

post #1 of 12
Thread Starter 
I got this for $75 brand new and sealed and it's a great card but there is a 2D clock issue that's pissing me off. When I run low-end old games like Diablo 2 / Diablo Hellfire it wont kick up to 3D speeds, not a issue considering how old they are BUT I loaded up minecraft last night to play with my nephew and cousin and my fps was half of what my GTX 260 192 core was, well apparently Minecraft doesn't kick up 3D speeds. So I make a thread on the forums and the best I got was "just install shaders and it will fix the problem"....well it did BUT shaders look like utter trash because my version of minecraft is old and I cannot run the proper optifine files. (It looks like a super bright 3D world.....it's not like the videos on youtube at all lol)


So is there a way to disable the power saving tool when I play the game that doesn't require me to overclock? I like the power saving feature I just hate how poorly it works for games tongue.gif I know the 7850 is a beast for overclocking but atm it's fine at stock speeds of 920/1250. I'm running the latest catalyst drivers as well so the "preset fix" doesn't work anymore (I tried to overclock my 2D speeds and it failed)

I figured from the lack of replies no one here needed aid, so I made a small tut over on the Minecraft forums. The basic version I overclock with MSI Afterburner and have idle and overclocked profiles. It's not perfect but it's solved my issue.

Unfortunately, overclocking with Afterburner doesn't seem to fix my problem. It raises my maximum clocks during higher power states, but it doesn't prevent it from doing the same exact thing as before--returning to idle or 2D clocks during certain 3D games. Maybe this is a drivers issue--which version of Catalyst are you using? I'm using 13.3 at the moment--I will try 13.4 and 13.5 when I have some free time.

I'm using 13.4 and make sure you follow the instructions, simply download afterburn and overclock wont work unless you enable overclocking in the EULA. I laid it all out on the minecraft forums. I'm just glad I can play with my nephew again with mods lol.

Once you enable the EULA overclock it will actually overclock and will disable power saving and should solve the issue.

Maybe try HIS iTurbo software? It has "Disable 2D clocks" option in it, under the settings tab. Haven't tried it myself, maybe it does the trick.

Like I said above, it doesn't in my case. It does raise the maximum clocks to the values that I set, but it doesn't disable power saving. I will post an update here if I can figure it out.

Edit: This seems to happen with all of the tools that I've tried, but I haven't tried the HIS tool yet. Hopefully updating to 13.4 and trying that will fix the issue.
Update: HIS iTurbo works! Using the "disable 2D clocks" feature, my problem goes away. It also has the same awesome fan curve control that Afterburner has. The only problem is that it doesn't seem to support voltage control with my particular card. While I'm at it, does anyone know if it's possible to bring the card above 1210 mV? That seems to be the limit in all of the OC tools which do support my card.

Yes, the lack of voltage control might be a big thing to some people but it's an easy and simple utility, Sapphire Trixx also has almost identical user interface while it has the voltage control, it doesn't has the option you need. Still though, I'm glade that you're almost there. thumb.gif
