[Official] AMD R9 280X / 280 & 270X / 270 Owners Club - Page 493

post #4921 of 9745
i have a strange problem with my rig

for now i'm running with only two 280x, 1 is the old manufacturer with 0.39 bios and hynix memory, the other with elpidia bios 0.43

now if i put the hynix one in the first pci-e slot and the elpidia in the second, the hynix run 15° hotter(already this make no sense, it doesn't matter if there is the cpu near it), but if i swap it with the elpida(so elpidia in the first and the hynix in the second slot), result is the elpidia run only 8° hotter

something is very wrong with the motherboard, which is an old asrock extreme 6 p67

all this whith mining, the problem persist even with cooler algo like x11 or heavycoin algo

@cremelo

Right, having something at 100% meaning it's throttling. So you really don't want everything at 100%, I'm guessing your cpu is the issue?

Anyone can clarify?

I think it is, I just remembered that I needed to overclock my old 8350 at like 4.9GHz to use my old 7950s properly, I recommend OCing your i5 to like 4.5 if you can cool it.


Also just to add,
Now my i7 is at 4.5 it rarely goes up to 100%,
Where as my 280xs does even when overclocked as high as it could.

Should I increase the overclock the processor for best use of GPU???? Do I have to use a standard clock for both GPU? like 1100Mhz on Asus ( 1070Mhz Stock ) and Toxic ( 1150Mhz stock ) and is Normal the second GPU off the fan when using the computer at idle?

I find it strange because I am not able to harness the full use of both GPU....

Side question: are both your cards 2x Dual-Link DVI?

I believe the processor is pushing the VGA =/
When I get home I will try to climb it 4.0 to 4.5 if the Vcore and temperature does not get too high.
this was my fear rolleyes.gif

Asus Have 1 x Single-Link DVI-D,1 x Dual-Link DVI-I, 1xHDMI, 1xDisplay port and Sapphire have 1 x HDMI (with 3D),2 x Mini-DisplayPort,1 x Single-Link DVI-D,1 x Dual-Link DVI-I...
I use HDMI and DVI on first and 1 DVI on Second.....

You don't need it to go 4.5. Just go as high as you're happy with it. If your game plays fine at the graphics you're happy with and at 60fps leave it be. There's no reason on fixing something that is isn't already broken

I didnt know you could use interfaces on both cards in CF. Thought all ports are disabled on the CF card.
At least my 7970's will not.

I know it's so cool!
I just found out like 4 days ago. Now I'm using my second gpu to show all my monitors, my 7950s had to have it on top.

Man I think it's way overpowered to have two. No games is going to be optimised to use both gpus. Reason why I bought 2 x 280xs is because I have to have two cards. I hate the look of a single card.

Of course they have to be the same. It will break one of the cards. They have to be in sync for gpu clock. There should be a way in your overclocking software to sync them together.
