AMD - How To Overclock The Official Way Using Afterburner + Step By Step Overclocking Guide + Comple

[justwondering]

Current settings :-

fans auto - volts (mv 1275)power limit +5 % 1115 + 1725 - temp =77 = score 2160

Is the temp are fair temp or it running too hot ?!

Where should i be going from here MV wise , Core and memory speeds....what is the max score i am likely to achieve ? as i may just leave it set as it is if for example , i am only likely to achieve a 2 % or so further improvement.

I do not want to over stress my card , as it is 2nd hand with no warranty , but i would like to overclock to a good speed but not over stress it

One thing i have noticed is that if the fans are on full or on auto at the current settings the temp remains pretty much the same.

Advice please ...

Voltage is unlocked already on my VTX3D 7970 X-edition , i have checked this using the test method on page 1

graphics card stock speed(1050 + 1425) , stock volts (1194) fan auto score 1923

fans auto - stock volts (mv 1194)1085 + 1575 = score 2035

fans auto - stock volts (mv 1194)1100 + 1625 temp = 72 score 2093

fans auto - stock volts (mv 1194)1100 + 1675 temp = score = 2123

fans auto - stock volts (mv 1194)1105 + 1700 temp 74 = 2133

fans auto - stock volts (mv 1194) 1115+ 1710 temp 74-75 = 2153

fans full 100% - stock volts (mv 1194)1115+ 1710 temp 74-75 = 2149 fans on full

Started to show artifacts ****fans full 100% - stock volts (mv 1194)1125+ 1725 temp 74-75 = 2166 fans on full ***

Scaled back graphics 100 % fine no artifacts ****fans auto - stock volts (mv 1194)1110 + 1725 - temp 70 = 2152 fans on full ****

fans on full - volts (mv 1250)1110 + 1725 - temp 74 = 2121

fans on full - volts (mv 1250)1110 + 1725 - temp 74 = 2121
Power limit set to std + 0

Just got a 7950 and noticed gpu-z reports voltages wrong ? I put in 1.00 volts and it's reporting back as it's hitting 1.498 volts when I run heaven bench and click on max voltage hit sensor on gpu-z VDCC.How can it hit 1.498 volts the limit is 1.3 on msi afterburner ?

Use something else to monitor, sounds like gpu-z is reading it wrong. Try HWINFO64.

yea I got that already hw monitor pro

great card though does 975 - 995 mhz 1575 memory on stock voltage of 0.95 volts

Good sample.

Does anyone know if the overclocking method on post 1 is still current for overclocking crossfire 7950's on win10? I have sourced the latest versions of the programs mentioned there. Since I want to start playing about with this.

Wow, forgot about this thread.

Yes should still apply.

Hi Matt,

Thanks for letting me know. Is there an official stance on 1 bridge or 2? as when I went to 2 bridges, the firestrike bench just seemed a bit smoother and got a small 11 point bump (which could be a fluke).

It's been a while since i tested it to be honest, but from memory i don't recall there being any difference. If you have two bridges attached only one is used.

My card seems to be voltage locked but I can bump it from 945 MHz to 1000 MHz. Got driver crashes at 1025 MHz unfortunately. Haven't tried to find max VRAM clock yet but a bump from 1400 MHz to 1450 MHz works. Was stable for a 4 hour Dying Light session.
