[GA-P55A-UD5] [rev 1.0] freezing, crashes, reboot while gaming

[Dark Mantis]

What PCIE slot do you ahve the card installed in?
Do you have any other cards in the slots?

The BIOS version is listed as I thought so now you can go on  the manufacturers website and see if there is an updated version.

the gpu is in slot 1
the revodrive is in slot 3

[Dark Mantis]

I am sure that your problem lies in the fact that because you have the Revodrive(or any other card for that matter) in  PCIE Slot 3 it is restricting the performance of PCIE Slot 1 from x16 to x8. I hope that is clear.

[wazabe]

in the manual its not supposed to be the case
they say: 2nd slot share bandwidth with slot 1, so if u used slot 2, the slot 1 will be at 16
but i have nothing in slot 2
the revodrive is in slot 3
hope its clear enough 

so yep, something is wrong with :
- GPU-Z
or
- the mobo (puting my slot 1 in 8 instead of 16
or
- the card messing with the bandwidth
or
- the revodrive messing with the mobo and/or bandwidth of the gpu
?

If you check your manual on page 54 it explains in detail why the speed is only x8.

Turbo SATA3 / USB3.0 (Marvell 9128 /NEC USB 3.0 Controller)
Determines whether to set the PCIe speed of the Marvell 9128 or NEC USB 3.0 controller to PCIe Gen 2. Please note that when only one graphics card is installed on the PCIEX16_1 slot, it will operate at up to x8 mode if either one of the two controllers is set to PCIe Gen 2.

So to enable x16 you must disable the USVB3 and SATA3 controllers. Simples!

tadaaaaaaa
it works

so this was the problem, thanx a lot mantis !

but now i bought this mobo because of the sata3 and usb3 possibilities, that i supposed are now off ?
are there any mobos out there that dont have this kind of problems ?

[wazabe]

talked too soon.

cod4 froze again and crashed.

[Dark Mantis]

Oh! The joys of being an early adopter. I am afraid I can't really answer your question regarding the use of USB3 and SATA3. I am in the same boat myself so to speak.

[wazabe]

well thanx a lot for all your help

i think i just have a bad gpu, i will RMA it

i plugged my old 9800 and no crash, no freezing nothing.

[Dark Mantis]

Well good luck and let us know what happens in the end please.

Its likely drivers for the GTX 470 that are the problem, did you try any beta drivers that might of fixed it? Even the odd setting set to high can cause problems.

SATA 3 for you WD HDD is simply not needed it can not break SATA 2 speeds only a hand full of SSD's can break them speeds.  

I am sure that your problem lies in the fact that because you have the Revodrive(or any other card for that matter) in  PCIE Slot 3 it is restricting the performance of PCIE Slot 1 from x16 to x8. I hope that is clear.

Thats not ture the PCIE Slot 3 (listed as PCIEX4_1) runs off the P55 chip at (PCI-e 1.x) x4 if PCIEX1_1 and PCIEX1_2 slots and the eSATA connectors are not used. The PCIE Slot PCIEX16_1 & PCIEX8_1 are what share the bandwidth plus the USB 3 and SATA 3 if set.
