ongoing 7970 crossfire problems

How much power does an ssd draw? my setup has been up and down recently but the last 24 hours it has been unable to run at full load for more than 5-10 minutes, the only thing thats changed in the last 24 hours is adding a 120mm fan and a single M4

any chance my psu is screwed that the tiny bit of extra load is pushing it over the edge?

No

The SSD and fan would only draw about 10Watts together.
 
So i just tested with another PSU straight out of the box

with one 7970, the new psu (750w) squeeled like hell, this time i left the PSU outside of my case (on the opposite side to the graphics card

both the graphics card(or slot, impossible to tell) and PSU where squeeling and whining like mad

any ideas? what could cause both the PSU and graphics card/mobo to whine and hiss and squeel like that?

didnt dare benchmark until my pc rebooted as it sounded terrible after a few seconds of benchmarking

Have you got another machine to try these in?

What is the PSU?
 
It was only running one 7970, the other was totally disconnected
my friend is bringing his rig over tomorrow, currently running 6970 crossfire, I guess i should test each 7970 in his machine 1 by 1, then in crossfire and see if he gets the whining and what not

if he does it would suggest its the cards, does that mean i need to RMA them?

can you think of any more tests I should try

many thanks for all your help
 
the hissing only happen when you load up a game ect?

If so then the hissing will be coming from the GPU, my 4870x2 did that and so did my 6970's its nothing to worry about.

And if the pc is restarting while gaming but not BSOD'ing then it does sound like the PSU isn't big enough but then again ive seen many systems running crossfire 7970's on 850w psu

I had loads of problems with my 6970 crossfire setup with crashes and BSOD in the end i sold them. Shame nvidia have gone for this stacked DVI port on the 680's so im going to have to try 7970 crossfire which could end up costly! :(

But his PSU is only really 360Watts on the 12V rail.
 
there is no BSOD, just a total reboot of my machine once the crossfire is running 100%

the top card seems to be higher temp, but even with the fan set to high my rig still reboots after a few minutes of full load

I hate problems like these, is one of the cards giving out, my psu giving out or my mobo giving out

takes so long to test each component on other machines
 
When you get sudden restarts that's most likely the PSU not being big enough, i ran 2 4870x2 on a thermaltake 750w psu and had the same in BFBC2 on the start of the single player when you go under the bridge.. After it restarted i touched my psu and it was so hot you couldn't touch it lol. Then i upgraded to a 1000w one.

So i would probably say get a 850w corsair psu( or bigger ), im sure someone can recommend you one here. But if someone you know can borrow you a psu before you spend £150 then do so just in case its not that!
 
ok latest update

looks like the cards are fine

just ran both cards in crossfire on my friends ninja pc, played metro 2033 on full settings at 110fps for a long time, both cards were over 70 degrees (his mobo had the VERY close together, closer than mine) but they didnt crap-out for 20 minutes solid

i turned the fan settings on his MSI afterburner profile back to default and one card (top card) reached 80 degrees but the system stayed completely stable

sounds like the cards are fine, something in my system is giving out, time to buy a 850w or 1000w corsair PSU what do you reckon?

Take a look at the PSU's i have put in my eariler post.
 
 
Assuming from your first post you are playing battlefield 3. Try testing your cards on your rig using a different game. I cant use crossfire when playing battlefield 3 it causes a blue screen after a random amount of time between 30 seconds to a hour.

My machine reboots after 5 minutes of BF3 or Heaven 3.0 benchmark etc
 
my performance on my 7970s has been pretty weak so I think I'm going to bite the bullet and get a new mobo/cpu psu and a corsair h70/80 cooler.

could someone spec me up? i also do 3d/2d editing (after effects etc)

£250 (ish) CPU
£250 (ish) mobo
I plan to OC the chip, so h80 or h70?
 
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail £175.99
Gigabyte Z68X-UD3H-GEN3 Intel Z68 (Socket 1155) DDR3 Motherboard £122.98
Corsair Enthusiast TX850M High Performance 850W '80 Plus Bronze' Modular Power £104.99
Corsair Hydro H80 High Performance Liquid CPU Cooler (CWCH80) £69.98

How does that sound?
