Some problems while overclocking r9 280

[Kudzė]

Hello, so I'm trying to overclock my r9 280. the GPU clock is at 1100 mhz. (on default it was 1075mhz) I am using Amd OverDrive to overclock it. But when I run my unigine valley benchmark. The GPU clock tops out 950mhz. How I can fix this?

Put the preset to EXTREME and see if the top clock changes

I dont know why but it starts as 1100 then goes to 100% usage then goes to 950 and then instantly jumps to 1100 but with 64% usage. And then goes to 950 with 100% usage and it jumps couple more times but finishes as 950 with 100%. I dont understand this.

If you have the latest AMD Drivers turn off power efficiency

1 - don't use Overdrive
2 - Use Afterburner
3 - Valley sensors are crap
4 - R9 280s usually top out at 1150-1200.
5 - keep temps under 85*C
6 - set power targer in AB to +20%
7 - add +25mV
8 - test all day

I already did this. Thats why it went from constant 950 to jumping 1100 and 950.

1 and 2 - I started with it. And then i noticed this and jumped to Amd OverDrive.

3. I look at overdrive status.

4. Cool

5. Ok

6. Allright

7. Ok gonna try

8. Ok

I dont know how or why but it now doesn't jump  I did everything that guy with 8 points said. But i cant change core voltage

It seems that i got 1155 stable. On 1160 (ok nvm as I'm writing this post i saw artifacts on 1155  going back to 1150) there were some artifacts. I did everything but now i have two questions. 1. Do I need touch memory clock.

2. i cant change core voltage. Its grayed out any ideas? But when I first launched afterburner i could change it.

Enable voltage adjustment via advanced options
1150 is good, add more voltage for higher clocks

I cant find that option. If you're talking about those: http://prntscr.com/azxo1t Its already enabled.

Valley crashed after ~10 mins in 1150 so i'm going now with 1145

Hmmm, odd.

Hmm you didn't answer me this  : Do i need to touch memory clock?

no for now. memory bandwidth is plenty on the 280

So how i can change core voltage?

You may try other overclocking software....but it depends whether or not voltage adjustment is enabled for your specific R9-280 model.

For examples:

• Sapphire TriXX
• ASUS GPU Tweak

Back in the day when I had a few Radeon HD 5850's, one of them was a XFX one (I had three; the other two being Sapphire made).

MSi Afterburner did not have voltage tweaking available for the XFX card. Weird thing was, when I fired up Sapphire TriXX, I could adjust the voltage -- and it was verified in GPU-Z.

 

Some manufacturers (Gigabyte is a known one) disables the option to change the  GPU core voltage.

Speaking of that, which R9-280 do you have (manufacturer, and model)?

Mine is Gigabyte with Windforce cooler. I think i'll download gigabyte oc guru then.

Hmm that didn't help me. Its grayed out in gygabyte oc guru too.

As I mentioned, the reason I asked what is the make and model of your R9-280 is because Gigabyte is known for disabling GPU voltage adjusting. This is either something in the vBIOS, or some kind of physical hardware limitation -- I am not 100% certain.

 

You can try other overclocking programs...before giving up...

• Sapphire TriXX
• ASUS GPU Tweak

If you want to test your might  you can try flashing a different R9-280's (AKA HD 7950) vBIOS onto your card, and see if you can unlock voltage control. 

 

** THERE ARE RISKS INVOLVED ** It is come-what like flashing the BIOS of a motherboard to another COMPLETELY different board (i.e. ASUS motherboard BIOS to a Gigabyte motherboard)

Ech what ever. Still i got +75 mhz increase in my gpu core clock. And it seems to be stable. For now I have enough performance to max (almost) everything I play on 1080p so I'll mark this post solved. I'm happy because i got ~5 fps boost in performance on valley benchmark :D. Ofc i'll try these programs. Thanks for helping!
