Really Need Help 5870 stability

post #1 of 17
Thread Starter 
I have been having issues since getting a second HD 5870 and setting up crossfire mode.

Problem(s):
Was crashing in a few games (didn't try a lot of em)
Started trying ways to test temps and stability Found Furmark 1.8.2
Ran MultiGPU mode and fullscreen with 1920 x 1080 (my TV resolution)
Went up to 85c on both counters and then looked like it was crashing closed out and program went to unresponsive. When I clicked on it to run again, it crashed my PC O_o

Things Ive Done:
I wiped the slate clean and used a method listed here http://www.techpowerup.com/forums/sh...ad.php?t=52502
to remove all traces of the old setup and fully reinstalled everything including my Chipset.

That primary game I did as my first test is Rift, I assumed they were just not stable in thier programing for it yet but after this furmark crash and Futuremark programs crashing Im a bit worried. Single card worked fine, and temps were in decent ranges

My Info: (if more is needed ask)
GPUs: XFX and a HIS Radeon HD 5870 1gb exact match (NOT EVEN OCed
Processor: Inter i7 930 @ 2800 OCed to 4.0
Catalyst 11.4
12GB DDR3
ASUA P6X58D Premium
Case: http://www.newegg.com/Product/Produc...ke%20VH6000BWS (plenty of room/airflow)


What I need to know is Should I return this card? What is wrong with my setup? Im out of ideas on what to do, I don't want to waste money in the long run. The motherboard is placing the two cards very close but there isnt room for more space, I was told it wont matter.



Ran a second Test on Furmark. Crashed in 10 seconds at 70c

Did you test the new card separately to see if its working properly on its own?

Was actualy going to try that next. But wanted to know is there a "good way" to go about removing a card. Should I disable Xfire then shutdown remove etc or should I dot that but also wipe drivers?

I would uninstall current drivers, shut down the PC, replace the card, install drivers again.

You need to find out whether the problem is the new card or crossfire.

10 mins running single GPU Furmark and nothing crashing, temp is topping at 71c which is about right I would think.

So now what could it be a power issue? I have a 850w Cosair H850WX
I have the 2 cards, motherboard and 5 fans and a cosair CPU water cooler (the pre made one they make forgot name)

I read before hand if that would be enough. was I wrong? Is this all just coincidence and furmark (multiGPU) and that game I tried just unstable with Xfire?

so here is somthing interesting.

When Putting second card back in (trying to have them switch spots on the board) I musta hit something or messed something up and reset my bios settings ;/ so I decided to go with it (overclock of CPU was gone and went to default)

I had both cards in and installed the drivers and did another furmark run with same settings and went about 8 mins and no crashing,. temps got to 87c though but I might be ok.

So im going to hold of on re OCing my processor and run tests. I might re OC it but retest it for stability WITH the two cards, maybe it was a power thing or maybe something wasn't syncing right.



Put case cover back on, it has a large fan on the side but I guess that wasn't enough, was hitting 91c this time, how close am I to the dead point? Thought it was 90, what Can I do with this issue assuming the other one is fixed?

Anyone have any thoughts?

Just when I think its working I try somthing else and it freezes. Even some what simpler games, I was trying this Total War Shogun2 and It froze up. I was monitoring and temp was 72, and the load went from 70s to 90s as last recording to the log.

Why Doesn't crossfire work for me

need to look at increasing your IOH and ICH Vcore, this is your voltage for the southbridge and PCI-E lanes. normally you only need to increase this with 3 or more cards but by the sounds of it it might help you.

Also expect your cpu to want about 2 bumps more Vcore when overclocking due to the added +12v load caused by the cards. check your +12v board voltage with Hardware monitor or under health in the bios, make sure it isnt going too far below 12v, you want it ideally anywhere between 11.7v and 12.3v. if your lower than this or higher then you may need to get a better power supply or invest in one of these

This however will only fix your stability issues not your temp problems. for that ill post in your other thread about the temps

ive been running with only 1 card atm but with 1 card my bios hardware monitor is saying my 12v Voltage is at 12.081v so If I put in both cards and went into my boards (AI tweaker) I should check to see first if its lower then the values you specificied? and if it is I should manual incress IOH ICH voltages a bit?

Roughly how much should I increase?

These are the related settings on the board

IOH Voltage
IOH PCIE Voltage
ICH Voltage
ICH PCIE Voltage


do I need to do both or just the PCIE?
