ASUS X79 Deluxe erratic instability.

Silent_Scone · 16 Jan 2014 at 00:28

Hi

As in title, not sure why but since rehousing my x79 rig and putting all 3 GPUS under water I'm getting strange behaviour. It only happens very occasionally but the PC will start to hang, then start responding and hang etc. Won't BSOD. This is at stock or when overclocked. Doesn't seem to matter when. It doesn't seem to clear itself so I'm forced to reboot manually. It isn't a major issue as it only happens very rarely.

The only thing I can think it might be is where the quick disconnects are connected to the GPUS they're pushing them slightly too much in either direction and not making full contact. May try to adjust them but wondered if anyone had had similar. May post in the graphics section too.

Thanks

Only time I've had somthing similar was a dodgy psu. Eventually found out it wasn't supplying the correct wattage and system froze up until I restarted. It sort of slowed down then hung without bsod. Tended only to happen when pc had been in use for a while.

Might be worth running a logging program to see if you can narrow it down to a problematic background task :confused:

Funny as I've recently switched to a super flower 1200w. It's stable enough under load but I know that doesn't rule it out...I may stick the enermax back in if it continues. The only other thing that makes me think it was related to the GPUS was when it was having a spell I tried disabling Sli and it hung and rebooted.
I will be surprised if the Super flower is at fault but stranger things have happened

I too would be suprised if the psu is at fault in this case mine was a mid range corsair one. Different leagues completely. Pretty sure psu can be ruled out in your case.

I don't suppose you could turn off individual GPUs and see if you could narrow it down from there.

I'm sure you've already checked but do you use any gpu logging software during the hangs? Any spikes in usage or anything :confused:

Not that I've spotted but I've not logged the files so may start to do so. It may be driver level. I've not tested each individually on their own extensively but did enough overclocking work on them on air individually without any adverse lockups. Although I've obviously clocked a good few hours on each card in SLI both since owning them and since putting them on water (as I say, probably one or twice in 4 to 5 hours of game time tops. If at all) This is something new since rehousing, only real change is obviously GPU blocks and PSU...but also drivers

.

I've done a few things like loosen the waterblock to the CPU slightly and try and gently re slotted the GPUS whilst in situ. I will do a driver clean up and reinstall the latest WHQLS and report back

Hi MJFrosty, l would do a fresh install as l had too after overclocking my Asus x79 DLX+ 4820k to 5.0ghz1.5v widows was corrupted.

When going into windows just got a blue background not a BSOD now and again. Did a fresh install+ latest drivers, running as sweet as a nut at 4.6ghz 1.344v.

Silent_Scone · 16 Jan 2014 at 09:47

Ahah, as much as that distains me to hear, I get that sometimes, more often than I'd like. You press desktop and it just sits at a blue background?

in fact I used to get that before rehousing occasionally. You'd press desktop and it would hang... Thanks mate, might have to brunt a full reinstall then...again. Wouldn't surprise me considering the amount of OC runs I've done that have fallen over when trying to benchmark. Don't think Windows 8 is very forgiving in that respect.

Also 4.6 at 1.344 is a nice OC on that chip

Thank you.

Yip, l had spent a good couple of hours taking my time altering the settings in the Bios[Win 7] So when it hangs then pressing the restart button and the number of reboots can not do your OS any good.

Really loving this mobo its got to be the best Asus DLX yet and something to consider if you want a x79 mobo. I think its a better buy than the lower range x79 ROG mobo's, all things told its so easy to overclock.

Do you think there's any advantage in running Win 8?

Silent_Scone · 16 Jan 2014 at 10:09

Given the problems I'm having, probably wouldn't advise upgrading to it

.

TBH mate it's more a hindrance. The only reason I decided to upgrade was because BF4 Beta at the time was having terrible performance issues. seconded on the motherboard too, it's a great motherboard, but so was my PX79 Pro, so...

OLDPHART · 16 Jan 2014 at 10:19

I,v had no problems at all, only that one.

l was more worried about my TeamGroup ram not working properly. But the Asus x79 Dlx recognised it straight away as its on their ram list for the mobo.

Yes l read all the posts about BF4, but was bought the game for Xmas and it ran no problems with my x58 930 SLI 670.

Can't believe how much quicker x79 is over x58.

It is night and day, great chipset. Although as I just said in reply to your ROG board post.

*Cough* native sata ports plz

Anywho, apart from the occasional gremlin it's been performing brilliantly, GPUs included. Just don't like niggles that appear from nowhere
