How to overclock a 7850 past 1050MHz?

Nice to know, will try CCC to start with but have Asus GPU Tweak (3 versions) downloaded ready to try, reading through this thread at the moment.

So I tried my hand at overclocking my XFX 7850. Core: 1200, Memory: 1450. Sadly I need to bump up my voltage in order to obtain that.

Dunno if that's a good OC really.

Whatd you do to be able to adjust the voltage of the XFX card? I, as well as some others, haven't been able to do so. Are you using Asus Gpu Tweak? If so what version?

Card - Sapphire 7850
Cooler - Accelero S1 PLUS. Passiv cooler. No fan.
Chassi - Fractal Design XL
Chassi Fans - 1 Front, 1 Back 140mm @ 1000rpm

Stock Temp - 54
OC Temp - 86
OC 1200/5800 @1.165

Stock scores VS OC

Asus website has them, That is where I got my version from.

Edit: Make sure you download from the global download link.

Cheers, got 2.0.8.3, and whilst it now lets me adjust the voltage, I still can't up my clocks beyond 1050 as that is the max of the slider. :confused:

go into settings and in the tuning section put a tick in the "overclocking range enhancement", that should increase your overclocking range.

Sapphire Trixx. No version of GPU Tweak let me change the voltage

I just got a Asus DC II 7850 today, was going to flash it with the same TOP bios as mentioned on here not sure I will now......

That's what I did, which allowed me to mess around with voltage, but the GPU and RAM sliders still max out at the same as CCC.

Don't think there is a way to increase the limits in ccc?

I mean that in GPU Tweak the slider still maxes out at 1050 (the same that CCC maxes at).

hmmmm, until I get mine installed this evening i cant really comment

Asus GPU tweak maxed out at 1050 for me too even with the overclocking range adjustment on, But using sapphire trixx lets me go as high as I want.

krooton · 18 May 2012 at 13:55

And Trixx will work with my VTX?

How do I revert back to my HIS7850 Bios?

When I used the method on Page 43, I did save my rom and atiflash called it "Backup.rom" by default.

But when I run "atiflash -p -f backup.rom" I get an error.

I have renamed "backup.rom" to "his7850.rom" and run "atiflash -p -f his7850.rom" but nothing happens.

I'm afraid that my card may meet an early death like 555BUK's. :eek:

Guy`s, I am using this version, ASUS GPU Tweak 2.0.6 and I can go as far as 1700+ on the gpu clock and mem clock can also go way above what you need, Voltage tops out at 1.225 I think.

Trying to use this software but I dont see an option in settings\tuning for 'overclocking range enhancement' using ver 2.8.3 and wont go beyond 1050mhz. :confused:

You have to put ASUS Tweak into 'Advanced' mode to get the option to unlock

Someone took a screenshot of where that is in the thread.

What's the safe voltage for a 7850?

That's basically what I've got with my sapphire one, 1200/1475 @ 1.185v seems a pretty good OC to me

I guess so they all seem to work with each other, trixx makes it look locked as in the bar only goes upto 1050 and as soon as you set the core to that the bar gets bigger and allows you to go further.
