Good day peeps my first build my first issue

[cnking]

HEY.

so I built this system myself had it a 9 months or so , no problems at all until recently I installed another card not sure if the problems started rite after or not...


I have
AMD 9590
sabertooth 990fx r2.0
corsair vengeance pro ram 8 G
2 x SSD 250 gb each
1 X HDD 2 TB
2 x AMD r290's (crossfire)
Corsair AX860 platinum

My issue is when playing bf4 and the battlefield hardline beta my pc frezzes randomly and I have to cold boot.

when playing hardline the wattage being used was around 750 watts and max power ever drawn was 824 watta from crisis 3 bf4 normally draws around 4-500watts.

the event viewer shows no errors really only logs the fact that I have switched the pc off due to the freeze.

both programs are being aloud in firewall also.

also all temps are fine the r9's are tri-x version
OC , gpu doesn't go above 75 cpu also being cooled by a h100i temps for cpu also fine

Does the problem go away if you remove the second card?

 

[cnking]

im going to give that a go now

 

[cnking]

would a psu cause a fatal crash for running a 90% ? or is it likely to be a faulty card do you think

 

[cnking]

Works fine on one card swapped them around and put both back in seems fine now though the crashing was very much all over the place may not crash for an hour then crash. Or I may go away and come back at the spawn screen on bf4 and it will be frozen

you should be fine on the PSU side

http://www.kitguru.net/components/p...rofessional-series-ax760-and-ax860-review/11/

kitguru was able to push their ax860 to over 1000w

most of the higher end power supplies are rated lower than their actual max sustained output.
on cheapo/poor quality power supplies one might need luck even getting close to the rated power.

Oh ok thanks, well I tried it for about 40 mins with one card was fine also tried it with both swapped around for about the same time and it was fine I'll test it for few hours today maybe a card was not seated as well as it could have been ?

It's possible, keep us posted.

 

[cnking]

Ok so because I took a card out cf was disabled. I enabled it and it crashed within a few mins, my screen has gone red this time requires a hardboot

 

[mfenn]

Try running with each card by itself for a few days. If you don't see any crashes with a single card, then you're either looking at a PSU issue or a motherboard issue.

I suppose it's possible that your motherboard has a defect in its second PCIe x16 slot causing the machine to crash when the second card is inserted, but I think the more straightforward and obvious answer is that you don't have enough PSU capacity. You have one of the most power hungry dual-GPU configurations possible when you consider that the R9 290's are the factory overclocked version and you have one of the insane 220W AMD cpus.

 

[cnking]

yeah I know that maybe mobo...I ran 3d mark and it used both gpus 100% and I got a pretty decent score at max setings so I guess the gpu is ok. I may end up selling all this and getting an intel/NVidia set up

 

[cnking]

ok so been switching gpus around one at a time seem fine, had them in different pci to, I managed to make it crash 3 times in a row, switched on pc, opened up afterburner and origin slected to join a bf4 server and crashed rite there..it did that 3 times in a row after cold boot and then didn't do it again this is with one gpu and ofcourse low power consumption, so rules out gpu's and psu.

when it crashed before afterburner was not on.... almost like its conflicting with the bf4 engine as it crashes with hardline too...it has crashed on other games too but one once...

really don't know the answer

 

[mfenn]

Is it the same GPU that makes it crash 3 times in a row? Try running with that one for a while and see if you get any crashes in normal gaming. If so, you can be pretty sure it's that GPU. Otherwise I would lean towards the motherboard.

 

[cnking]

yeah think it may be mobo, its crashed with 2 cards and with one its an odd one really I don't think ill ever find out

If the motherboard isn't under warranty, you could take this opportunity to upgrade to a Haswell rig!

 

[cnking]

im planning on getting a devils 4790k not sure wich mo bo tho? and a matrix platinum 980 ...

ive check my voltages I did get a 3.3V warning not sure if it was too low or high tho....
also wilst checking voltages with the mobo software 'the ultimateforce' sensor recorder...
my vcore is up and down....going between 0.864v-1.500v wilst im typing this post... don't know if that's normall

 

[lehtv]

4790K is a good pick. Mobo depends on whether you intend to overclock. On a midrange SLI mobo e.g. Gigabyte Z97X-SLI you will not be able to OC very much, you need a high end board (preferably 12 phase) and high end cooling (TC14PE / D15 or better) to get a significant boost over the stock 4.2GHz 4-core turbo.

Why 980? that'd be a downgrade from r9 290 crossfire.

Agree on all fronts. I would keep most of the current rig intact, just swapping the CPU/mobo.

OP, the Vcore changing is normal, it's part of the chip's built in power saving features. It downclocks and lowers its voltages when it's not under heavy use.

3.3V being out of range is more serious. 10% is the maximum difference, so 2.97V - 3.63V, but ideally you'd want to aim for a much tighter threshold. However, I wouldn't expect a high-end PSU like the AX860 to have a problem with keeping voltages stable, even in an extremely crossloaded config like yours. I'd suspect the mobo voltage sensor is giving a faulty reading. That being said, the main voltage rails are easy to independently verify with a multimeter.

 

[cnking]

kool, well I was thinking 980 because ei keep being told how effiecient they are and my 2 x gpus are very hungry as my whole system really, also in bf4 I have a weird thing going on wer it used between 0-10% of gpu 2 most other games I play don't even use xfire so I just figure id be better off running 1 980 thinking matrix platinum.

 

[lehtv]

980 matrix platinum is obnoxiously expensive, you'd be much better off with even a single R9 290 and a bit of OC on it. I mean... $650 for a mere 15-20% or so improvement? Hold off until you can get a reasonable upgrade (at least 40-50%) for $300-400, and your CPU needs upgrading first anyway. If I were you I'd just upgrade to i7-4790K setup and see how the 290 crossfire works with that

 

[cnking]

yeah sounds like good advice...I like the maximus mobo but don't know wich one? there is the
Formula
Hero
Gene
Ranger
Impact
Crossblade Ranger

EEK!

I like your choice. 980 Matrix is all you will need for awhile..

ASUS ROG boards, as with most "ultra premium" boards, are generally a waste of money. You can buy a good quality board like the Gigabyte Z97 Gaming 5 in combo with the i7 4790K for $425.
