post #5101 of 22315
I am mining with one graphics card on my main computer and I've been trying to find out if it is possible to use the Intel integrated graphics for your monitor.

So I first tried this by disabling my AMD display adapter in Device Manager and then enable the Intel HD 4000. I turn off my computer, re-connect the monitor to my motherboard's video port and turn it on again. But I get no video signal. The HD graphics only seem to work when I remove the graphics card from the motherboard.

I hope there is a solution to this because I'd like to mine high intensity as much as I can without having everything be laggy when I'm using the computer.

I've been using my HD 4000 while mining with my 7950 for a while now, I think you need to play with your BIOS settings

You should hookup both your GPU and your iGPU to your monitor simultaneously, like one on VGA, one on DVI. Then set your iGPU display to your primary and everything should work fine

BTW I find it funny now that the Mac edition of the 7950 is now looking affordable compared to the other new cards in stock.

Not complaining.

I had originally ordered the XFX DD ones because they were the only ones in stock for a long time.
And yes, I know everyone says stay away from XFX... Like I said, only cards in stock at the time for a descent price.


So, here's my rather shabby setup...


2x XFX 7970's DD's
1x Powercolor 7950

I get around 1.5 Mh/s with all of them working.

Though I am having some SEVERE issues with heat.

All of them are in the 90's.
Even with really good airflow.


I am thinking about doing a milk-crate setup with the PCIe extenders and all, just thought I could get away with them being in my case.

Here's what it currently looks like, the XFX card that is mashed up against the Powercolor gets the hottest for obvious reasons.



(Xfire is disabled in CCC, was used to do some initial testing)


Clocks are (Left to right, XFX XFX PowerColor):

GPU: 925,925,850
MEM: 1375,1375,1250
VDC: 1.174,1.174,1.125
FANS: 100%

7970's get ~500Kh, 550 from room temp.
7950 stable at 500Kh.

Not sure what I should do to maintain hashrate, but lower temps to a safe level...
Don't want my cards melting or self destructing after I just got them.

If I have to, I'll do the milkcrate setup, just having to wait another week to get the supplies will be a bummer.

EDIT: Case door open, and window open... 0*F air is blowing directly into the computer...
Top to bottom temps: 72C, 96C, 77C

Also, I think all my cards are voltage locked, and don't want to risk bricking the card or voiding the warranty :/

Is it at all possible to undervolt the cards? It would help with the temps. I have my 7950 on 1000/1300 @1.53v for mining. Funnily enough that's actually gaming stable, I have been playing BF 4 for hours with no issues at those settings.

Check my thread here, it sheds some light on how much of a heat prison the reference shroud is.

If you have a side panel fan mount, a 120mm / 140mm fan will drop temperatures substantially

Sweet, nice findings.
I'll give that a shot, but I don't have any extra fans lying around.

Would it also apply to the XFX coolers?

It seems I cannot proceed like this until I set it up milk crate style..
Closed the window and side panel, and all cards are above 95C... This is getting absurd now.

Thats a chipped die. The TIM isn't conductive. The TIM you see around the die is the blob that MSI originally put on the card that spread all into those little crevices. Still haven't tested the card to see if it works or not. Too aggravated to try.

And this is why I'm a firm believer that GPUs should have heat spreaders, so this can't happen.

This takes me back, I did the exact same thing to my HD 7750. Now all the card does is report an error code 10 to windows, but what's really strange is I did have the card working perfectly after I chipped the die - 1 time. I fired up DiRT 3, and it was running artifact free, the whole 9 yards. Powered down the system, and it never worked again. After that, it's been dead for months.
