280X CROSSFIRE VS 290X

[Uncle Petey]

Oh dear... What cards are they?

 

[LtMatt]

1200 clocks at 1300 on the core crashes about 30 seconds into valley benchmark giving the display adapter has recovered warning

Core clocks at 1200 or 1300?

 

[Uncle Petey]

Also, have you done all the Afterburner checkbox stuff like disable ulps etc? Link to your thread Matt?

 

[robertchalmers1]

core clocks at 1200 core voltage at 1300 and its these cards

YOUR BASKET
1 x Powercolor Radeon R9 280X TurboDUO 3072MB GDDR5 PCI-Express Graphics Card £239.99
Total : £249.59 (includes shipping : £8.00).

Maybe Humbug can confirm, but i think to get voltage control working on those cards you need to use the actual powercolor overclocking tool.

didnt realise they had one i presume that would be instead of afterburner then

Aye, worth a try. You could always use gpu-z sensors tab to check and see if the voltage is actually being applied as well.

 

[Uncle Petey]

All that waffle about power phases and OC potential on the product description hopefully means there's a good reason that you can't hit at least 1200 with AB.

Good luck with the Powercolour tool

 

[robertchalmers1]

downloading the powercool app just now as for volts in HWinf64 it has the max volts as 1.200 which im assuming means the volts were not set to 1.250v. should i uninstall afterburner before loading the powercolor software

 

[Uncle Petey]

Try just resetting it and exiting.

 

[LtMatt]

Sounds like you may be volt locked. If you're feeling adventurous upload both your gpu's bios and ill edit them for you and try and give you 1.3v to play with.

 

[Uncle Petey]

It says this in the product description, so I'd hope not or I'd be fuming if I bought them and turned out that they're volt locked.

Features:-
- Multi Phase Design: 8 Power Phases for improved OC ability
- Digital PWM
- Ferrite Core Choke: Decreases ripple to deliver more stable voltage

Also, could this boost nonsense be having an effect here? I've never owned a boost clock card thank God, so I dunno.

the powercolor program is terrible, you cant make out half the inputted settings or anything.

also in afterburner where you can input a value in the box and press enter you cant seem to do it on powercolor program

 

[LtMatt]

Well myself or pete can edit a bios for you if needed.

 

[robertchalmers1]

i wouldnt know how to take a bios off a card or how to put it back on thats the only problem i have and its certainly not something ive ever attempted to try before

 

[Five.Stars]

Closer than I thought it was going to be, if I'm honest:
http://anandtech.com/bench/product/1074?vs=1059

280X crossfire is near as dammit the same as a 7990 so the comparison in the link should be roughly 280X CF vs 290X.

Whilst this is true, it can be noted that the Tahiti's can pretty much all be overclocked somewhere in the region of 20-30%

The Hawaii's overclocking isn't as prolific, so the lead could be stretched a bit if the cards are run non-stock.

Use Gpu-Z to save the bios to desktop. Then upload it to sendspace and give us the link to download and edit.

I wrote a bios flashing guide as well. Its for a 7990 but it also applies to 280X cards. Just ignore the part about the master and slave bios.

if you compare the program on the official site

http://www.powercolor.com/Global/download_PowerupTuner.asp

then to my version

you will see i have the whole bottom section for profiles missing as well as the section that gives you the values is missing as well
