ASROCK p67 extreme6 Top two PCIE slots not working.

[Taurian]

Hi first post.

 

I have an Asrock p67 extreme 6, of which two f the top PCIE slots does not work. 

CPU:   Intel core i5 2500k.

MB:    Asrock P67 Exteme6.

Graphics card :  Gigabyte Geforce GTX 750 ti (no power slots)

PSU: Zalman ZM600GV (600w) (Brand New)

RAM: Gskill Ripjaws DDR3 1600

Issue: No display when I plug graphics card in PCIE2(16x) PCIE4(8x).

 

          Debug code d6 on the on board LED. POST gives out 5 short beeps.

          Has display on the very bottom slot. 

          

Things i have tried so far, 

Tried another working card ( ASUS Strix GTX980) nothing changed.

 Reset CMOS by removing battery for a good 2 hours, using the CMOS jumper and also by the button at the IO panel.

Bought and replaced the BIOS chip with the latest version. Downgraded BIOS to the original version. 

Tried another working PSU cooler master V650. 

 

Don't know, what to do other than what i have already done. 

 

Any help will be really appreciated.

 

Thank you

had the bottom slot of my P67 Sabertooth dead, might be that the P67 chipset is just bad idk. i just know the P67 sabertooth is known through out all three revisions to have this problem and ASUS refuses to do anything about it

It's likely to be a chipset problem, so not much you can do about it except replacing the motherboard

Have you looked up the beep and error codes?

It is very likely to be chipset p67 b3 related, i had problem with asus p8p67 with 2500k, and at random moments both pci slots stoped working, when i re-installed gpu (plug it out then plug it back) it would work just fine, tried other gpu same problem..

Thanks guys for your responses. 

 

@kelvinhall05, yes I have looked up both codes. POST (5 short beeps): process failure. 

And debug code d6 shows no output console devices detected.

 I was reading through another post in another forum about the same issue and solution was to bend back a pin in the lga array which was bent. I checked my lga array with a microscope and couldn't find any bent pins. 

 

I was thinking the same thing about the chipset. But wouldn't it cause all the three slots to be dead rather than two dead and one working?

As far as i know top two slots are x8 speed when used both (sli) and third is always x4 speed.. I guess that x4 pci lanes are going through chipset and not directly to cpu ( that can cause your gpu to run slower then usual)..
