Asus Crosshair V Formula-Z + SLI + FX9590

[Selveste1]

Hey everyone,

 

I don't really know what the problem is with my rig tbth, but I will try and explain further, as I go along.

 

System information:

Software: Windows 8.1 Enterprise

CPU: AMD FX-9590

CPU-Cooler: CoolerMaster Neptun 280L (Push/Pull)

Motherboard: ASUS Crosshair V Formula-Z

BIOS: v.2101 (latest one on ASUS.com)

GFX: 2x ASUS GTX770-DC2OC-4GD5

RAM: 32GB Kingston 2133mhz

PSU: Corsair AX1200i

Drives: Samsung 840Pro 512GB SSD + LightOn BluRay/HDDVD burner and reader

Case: Lian-Li PC-A7110B

 

I have 3x SP120 Performance Edition in the front of the case, SP120PE in Push/Pull on the CPU-cooler, a 140mm PCIe outtake fan, a 120mm AirFlow fan from NoiceBlocker as exhaust and a 92mm NoiceBlocker fan as northbridge fan on the motherboard, since the mosfet got to warm when the room-temp raised above 30 deg C.

 

The problem that I'm having is, that when I put my second GFX in the computer, and activates SLI the computer plays really well for about 30-40 minutes, and the it freezes, and the only option that I have is to remove the power and boot up again.

 

As far as I can see, with HWinfo64, the temps on the Motherboard is about 65 deg C, the CPU is around 68 deg C and the GFX around 90 deg C - I know that the GFX-cards are running a bit warm, but I can't do much about it, since we have around 30 deg C in the air.

 

I have tried to bench the computer and I don't get any errors on the CPU, when running Prime95 and neither when I run Heaven in loop for 2 hours - I haven't tried to run those two together, but since I don't seen any temp problems, or experiencing stability problems I don't think that is the issue.

 

I have tested the RAM with memtest89 and it has no errors. The SSD is working fine and checks out good.

 

I do believe this to be a temperature issue, since I haven't experienced it before now (approx the last two weeks, where it has been hotter than normal) but I don't seem to have the data to back my theory, since almost all my temps is within reason... So do any of you have any suggestions, or heard about problems with similar setups?

 

If you need any more info, just let me know, cause I'm really getting frustrated now...

 

Thanks in advance,

Henrik from Denmark

CPU 70°? Something wrong with your cooler or just a bad mount. GPU running at 90° isn't normal

[Bagmup]

9590 is a heat pump, FX chips start to throttle at 62c on the core, you're already at 68c. Need better cooling.

[Selveste1]

I have tried to repaste the CPU, and under 100% load with Prime95 I'm at 50-55 deg C now. But the GPU's is still running at 86 deg C under full load - room temp still around or just below 30 deg C. I haven't had a stability problem yet, but it have only been running for 10 min now, so they will come.

 

EDIT: I do not have any OC on either GFX or CPU - and can't do much more in terms of AirFlow in the case or to get better cooling on the GFX's

[foamygopher]

86 is still high for an aftermarket cooler on the 770. I have 2 windforce gtx 770's in my rig with much less airflow. While gaming my top cards around 70-75c bottoms high 60s. That's at 1226mhz. If you run a single card what your temps with that?

[foamygopher]

But then again I'm about 9°c cooler ambient temp tho..

try a custom fan curve on your gfx cards? i have one on my 780ti and that doesnt pass 65 on 100% load ( boinc/Folding @ home

[ExcitezR]

yea thats hot for 770s i have 2 280x and there hotter gpus make a fan curve heres mine i never go above 75c and it also hot where i am also i have them overclocked 

[Priller]

Most boards will throttle a FX at 80C not 62C. 62C is what AMD recommends for temps for 24/7 use.

 

 

It sounds more like a GPU issue since the issue only arises with the second GPU installed and the temps are high.

[WinNut]

Try pumping all fans up to 100 percent power, it will be loud but it will keep the system cool.

[foamygopher]

[Selveste1]

Hey, thanks for the advice, I do agree, it seems like it's a temperature issue with the GFXs and I will try a custom fan-profile on them, when I get back from holiday - after the computer have been running Prime95 all night last night, while I slept, it didn't get any errors, and it did never exceed 63 deg C.

 

Sunday night, I'll come with an update on how the custom profile is preforming. In regards to the one GFX question, the temp on a single card under bench, it get temps in the mid 70 deg C on air - with the case-fans on normal operations speed (regulated by the northbridge temps).

[VintageCake]

Well, that's just a lie.

 

They changed their cpu software something around half a year ago to a thermal margin system.

70 C seems to be fine for everyday use, and around 80 C is when it starts to throttle.

 

No idea where people got 62 C from, AMD didn't say anything about thermal limits, someone on overclockers uk forum sent amd an email about it and they said somewhere around 70C-75C will be okay for 24/7

 

 

 

 

Most likely, your problem is either driver related or just too much heat for that nvidia card

[foamygopher]

Hmmmm single card seems fine. Running sli shouldn't generate that much more heat. Have you tried both cards solo?

[foamygopher]

Tj for the fx 8350 IS 62°c. As far as I know the fx 9590 is just a cherry picked 8350 factory oc'ed. Anything over 61°c seems highly not recommended.

[Selveste1]

No I didn't get the time, the temps mention before is on the old card, I will try the new one in solo, when I get back Sunday night

 

EDIT: in regards to the temp on my CPU, I don't think it's a problem really. If I get those kind of temps under Prime, then I will never get them under normal gaming - unless it's the environment that heats up more.

 

On a side note, I'm considering to change out my LianLi case for a CaseLabs SMA8 later this month.

For the CPU that's fine prime does give the worst case senerio. So if it's stable then it's all good. I would try the other card solo if you can get a chance to just to make sure. Otherwise just go with the higher fan curve as recommended. As far as the case that's one hell of an upgrade!!

Nope. FXs will shut themselves off between 90-92C(8150s will go to 100C). Max 24/7 use temp from AMD is 62C. Remember it is a server based CPU. In a personal setup I would call just under 70C the limit for 24/7 use. 80C is where it should start to throttle and where I have found it to throttle. You can stop this by removing the thermal safeguards in the mobo bios but I would only use that for a benchmarking run that gets very close to 80C.

[foamygopher]

Hmmmm... I might have to dig out my 8320 and my crosshair v formula z. I was always paranoid goin past 62°c. Your info has me curious.

yea thats hot for 770s i have 2 280x and there hotter gpus make a fan curve heres mine i never go above 75c and it also hot where i am also i have them overclocked

Okay, just to come with an little update here.

 

I didn't have time to test anything last night, when I got home at 3am. But I have tonight, the air temp is around 28C and with the new card in single the card is running at mid 70C with heaven - and with the custom fan profile (100% when it exceed 70C) I flat out at 80C in SLI.

 

I do still have a problem though, cause after 2 hours of HEAVEN bench without errors the computer froze up, when the program closed, so I'm guessing it froze when the driver stopped SLI from being active - if this sounds plausible I'll try to format Windows8.1 Ent just to make sure that it's not a problem with the driver or the driver from my old AMD card (Radeon HD5870 Eyefinity 6) not being completely removed or some other problem.

 

Off Topic: My CaseLabs SMA8 is ordered, and it will arrived around start September

[Selveste1]

Okay, so I have tried to reinstall Windows, and it seems like it have solved some of the problems - I can't run heaven without the driver crashes and I need to pull the plug and reboot, but Vally seems to work fine with SLI. The cards gets in the low 80C with normal fan profile and high 70 with 100% fan profile.

 

I don't know why the driver crashes with Heaven and I haven't tried BF4 yet either, but it looks like the problem might have been resolved - but I'll return when I know more. Thanks for the help so far!

[foamygopher]

Cool man good luck!

Henrik, I would suggest that you underclock and/or undervolt your processor slightly. Coming from an FX-8350 user, the FX-9590 is basically a stable overclock of the FX-8350. However, as everyone here may or may not know, processors are like the lottery when it comes to overclocks. You either get a chip that can handle high voltages well or you don't. In your case, for all the FX series processors, the recommended temperature that you should NOT exceed is ~65C. Anything above that is not recommended. Especially if you are using what is basically a factory overclocked FX-8350.

 

So, my suggestion to you is as follows. You can either underclock/undervolt your processor and turn off the AMD Turbo Boost technology. Or, you can work on building a custom watercooling loop and use coolant instead of distilled water. As I'm sure you are aware, the FX-9590 is a TDP leecher. It needs over 200W of power supplied to it. And with more power needed, more heat is generated.

 

Let me know if you need anything more

[Selveste1]

So I thought that I would come with a little status update on the problem, since it still remains....

What have I done since last time.

1. Tried Windows 7 Ultimate 64-bit - no difference, SLI still only working one time and crashes at a random time of playing.
2. Reinstalled Windows 8.1 Enterprise - SLI configuration working for a random amount of time, then the screens turns black, random colours or goes into powersaving mode.
3. Tried the GFX's in his MAXUMUS VII GENE (i7-4790k) - SLI configuration working for a random amount of time, then the screens turns black, random colours or goes into powersaving mode.
4. Tried running with only one screen, two screens and tree screens (on both the AMD and Intel setup)
5. Changed my setup to the CaseLabs SMA8
6. Changed out the GFX's with a friend

The temps on the GFX's is not over 75C and the CPU never over 54C

 

And now I'm lost for more ideers - I'm starting to think that SLI just doesn't work with the 4GB version of this 770.
