Take the card out, reinstall it in Haf II, only card in the machine. and it shoots to 104 and shuts down......

I would say I have a problem with the motherboard in Haf I ya figure? But also what might be going on with the card? it was working perfectly just prior to the switch and now acts like is has no VRMs at all...

Well Haf I is back up with a single card and will stay that way, there is an obvious MB PCIe slot issue there Now I need to find an operating card for Haf II

Another option is the PSU ! May be worth trying a different set of leads to the GPU, ( if multi-rail i.e. old-school ! ))

dunx

P.S. I'm waiting four more weeks for an appointment to see a doctor for the resuts of a recent scan..... better not be serious LOL !

P.P.S. OC Force-III is in build..... swapped out my Xeon from the Asus Impact VII to another four card capable Gigabyte Z87 motherboard, R9 390X and another R9 280X and maybe an old HD 5870 to fit !

It gets better....

Got a GTX 780 running in Haf II not too bad around 16 minutes a collatz WU.

Tried to install a second one.......

Spark, flash, puff of smoke........

Dead GTX 780..........

And that's a brand new Crosshair V.

4 7970's and a 780 in two days.... with MB Pcie slot problems on two machines...

Rather depressing time around here...

I didn't want to upgrade this way......

I'd say there is a systemic problem somewhere. MB slot, cards or PSU. Unless you've got some metal dust floating around in your cases causing shorts. Thats nuts.

They are all in my office (where they have been for the last 4 years) no metal dust flying around. {snicker}

I lost a 7990 in Blackhawk 2 last month from the same problem. Slot two went south taking one of the GPU's with it, replaced it with a Sabertooth 990FX R3 which is running strong. (that's where my backup 7990 went also)

I'm pretty sure it's the MB VRM's giving out. Haf I is an MSI 990 FX which is my oldest board so it's not unexpected and I guess I'll have to RMA the Crosshair V and replace the MSI.

All the cards are way out of warranty now as are the MSI motherboards and with the abuse I've put them under I really can't fault them.....

I've figured for about 6 months now that I was going to have to upgrade cause they were getting old.

Still have two fully operational MSI's left out of the original 6.

Loosing them all at once is frustrating.

Just have to deal with it....... (short 3 7970's) with no backups.

The life of a boinc cruncher....

About $350.00 for a used 7990, 570 ish or so for a 1080 hybrid. decisions, decisions...

Sorry to hear about your hardware issues! I have a mobo with a bad slot that killed a 980 Ti. Fortunately it was an EVGA card and they replaced it no questions asked.

I've been looking at the 1080 Hybrid's myself. And 7990's. Two for one (actually four) just seems like the better way to go to me. I've never paid more than 300 for a 7990 though. Patience is the key.

I have achieved one of my goals in MilkyWay, which was to get a pair of 7970s to do 1+ million ppd.  Soon these guys will be going back to Linux.  @mmonnin I didn't do very much testing of MilkyWay in Linux, what was the performance like on your 280x?

post #207 of 221
How are you even running these in Linux? I've never been able to get a 7990 to run.
post #208 of 221
I've always had a decent % invalid/error rate in Linux. I've only ran the 280x in Linux. Most of the inconclusives end up validating. Not sure if the computation errors are just a Linux thing or the mix of drivers I was installing trying to get it to work. I'll never know if it would have worked sooner before all my driver installs as BOINC loads before the driver so BM thinks there is no usable GPU right after boot. Now I don't touch it with a ten foot pole in fear of screwing something up.

Yeah I know. patience. and pocketbook. With these FX CPU's, the most I will ever be able to run on the MB is two 7990's, with a 1080, I can run three.

The 1080, when configured correctly, produces about 5% more than a 7990 in half the power. In essence I would be putting the equivalent of six 7970's to work on one FX 8350 MB for 75% of the power requirements.

It's at that point where it will pay for itself in power savings just soon enough to justify the extra expense....

That's why the question needs to be answered. And 7990's are hot on the used card circuit right now, much like 7970's were two years ago... Eventually, that will dry up....
Now my personal philosophy is this, I would rather make the choice rather than have it forced on me, and I'm too close to being forced.

But I now have the space for another four 7990's if I choose to kick the upgrade can a bit farther down the road. (probably include motherboards and processors also) Do the cards now while there is still some life left in the boards and cpu's I have so when they become a have to proposition, It costs me less in the future...

but I don't know, Some people say I look at such things strangely....

and although they are still available, it's getting harder to find a 16x8x8 MB for an AMD chip. From what I've heard, both AMD and nVidea and moving away from anything more than dual Sli/Crossfire and in fact nVidea is actively recommending against tri-sli now... (the ideal being gaming GPU requirements today (and for the foreseeable future) do not require more than two GPU's.

Makes sense to me. 7990s sure do make the meter spin.

The 1060 doesn't even come with SLI connections. Not a gamer but from what I read fewer and fewer games are getting multi-GPU configs, especially more than 2 GPUs.
