PC keeps crashing when crossfire is used in game

funkeypim12 · Apr 25, 2016

Hello,

I have a system with 2 7950s in crossfire, this setup works great, but after i installed my new corsair 1600mHz 2 8gb sticks crossfire would just not work, pc just crashes whenever it is activated. I reinstalled amd crimson and used the amd cleanuputility too. after the 4th reinstall crossfire finally seemed to work. But how wrong could i be, i activated it, played a game for 20 seconds. freeze. retry. black screen and monitor loses connection. retry, bluescreen. retry, screen goes red and reboots. i tried all kinds of different ram setups they all crashed when playing a game. currently im checking either card because i think the fault is over there.

RIG SPECS:

windows 10
2 amd r hd 7950 DD normal edition (xfx pine group)
i7 2600K
8gb ram
amd catalyst version 15.11.1
MOBO MSI P67A-GD80 (MS-7672) version 2.0 and serialnumber "To be filled by O.E.M."

Kind regards,
Pim

It seems that what AMD has to load into memory for the game to take advantage of crossfire just doesn't like your new memory. I would try running memory diagnostics by pressing Win+R to open Run then typing in "mdsched" without quotation marks to run memory diagnostics. Please post back with results

Have you tried to go back to your original RAM. I'm not saying its the RAM, but since your problems began then, it's worth a shot.

I have one of those same cards. Double Life Time Warranty. It was one of their last cards to carry it. Now they have the same warranty everyone else has. I used it to get a new fan for card. One of the two seized up, they shipped me out a fan right away and put a link in my ticket for the exact procedure to change it out.

Have you checked your RAM with a utility like memtest86?

funkeypim12 · Apr 25, 2016

i tested both cards, they ran fine, and i already tried every possible ram configuration new and old so it cant be the ram.
i will now do the mdsched.

weberdarren97 :

well, i completed it but when i logged in i didnt get any log or message about it..

funkeypim12 · Apr 25, 2016

techgeek :

yes, i have tried that,already

funkeypim12 · Apr 25, 2016

festerovic :

`no, not yet, i am very confused as to how i run it so ill look up a tutorial first

techgeek · Apr 25, 2016

funkeypim12 :

You have two options, you can download a bootable USB version or a DVD/CD ISO. Once you have whichever you've chosen made, you boot from it. It will start to run the tests, no need for intervention. I would allow it to run for at least 4 hours, longer if you can. Sometimes it takes awhile before errors start to appear.

weberdarren97 · Apr 25, 2016

If it didn't provide a log or message then mdsched didn't find any errors.

funkeypim12 · Apr 25, 2016

okay, used rufus, but pc crashed at 44.5% done. when i booted it it wouldnt boot. i switched to old ram, didnt boot, i put the new ones back, and it did boot. wtf, testing with memtest86 now

funkeypim12 · Apr 25, 2016

weberdarren97 :

oh okay, nice.
should i stil use memtest86 then?

weberdarren97 · Apr 25, 2016

You can if you want, it doesn't hurt to have more than one confirmation

This sounds like a motherboard problem seeing as it won't take memory that we can assume is good since it was working when you took it out... I would try flashing the BIOS to the newest version available, to eliminate BIOS as the source of the problem

mlga91 · Apr 25, 2016

Do you have any XMP profile enabled on your BIOS?

funkeypim12 · Apr 25, 2016

mlga91 :

i didnt see that option anywhere but there is an OC genie button which, i think, overclocks the mobo for ram, something like that idk..

how do i know what version i have currently installed?

weberdarren97 · Apr 25, 2016

If it's not an option, then no, you don't have it enabled.

When we're not there with you, we're just trying to run through a form of elimination.

weberdarren97 :

the newest version states
"MSI recommend you to update BIOS with ME8 only if you are using IvyBridge 22nm CPU."
i dont know if i have that

weberdarren97 · Apr 25, 2016

They mean that it's not a required upgrade unless your CPU demands it, but the fact that it works at all means that your CPU doesn't demand it. I would do it anyway, though. I upgraded the BIOS on my motherboard every time a new one came out, although you don't have to do that. Many people will be fine with the original BIOS.

May be worth stating that I have an Asus board... I trust MSI much more for graphics cards than I do for motherboards

weberdarren97 :

hmm, i have a bad feeling about this.
is there anything else i can do to find the problem first?

funkeypim12 · Apr 25, 2016

i tihnk it would be nice to know my specs too:
windows 10
2 amd r hd 7950 DD normal edition (xfx pine group)
i7 2600K
16gb ram
amd catalyst version 16.3.2
MOBO MSI P67A-GD80 (MS-7672) version 2.0 and serialnumber "To be filled by O.E.M."

What PSU do you have? If it is not quaity, then it will crash your CPU

funkeypim12 · Apr 25, 2016

Bossyfins :

it does 750 watt

weberdarren97 · Apr 26, 2016

funkeypim12 :

What brand and model is it? Because if it's low quality and delivering unstable voltages, it could be the cause
