What method did you use to flash the bios to 3603 ?
... which 3603 did you use - (3603 - Win7/8) or (3603 - WinXP/Vista) ?

The i5-3570K only needed bios v.3203 to work with the P8Z68-V board ...
fwiw - I stopped all my P8Z68-V boards/builds at v.3402 ...

P8Z68-V BIOS 3603(for Win7 & Win8) <- This one through BIOS Ezflash2 Flashing is current.


Well, hell I might as well try the 3402 or even 3203 I have here all 4 last lined up on FAT32 USB stick.

(Kinda need to fresh my memory on how did clean MS-DOS flashing go again on these new bios styles, if the BIOS flashing really would be the key, but no worries I'll check it out, if needed. I was about to test 3202 next (last BIOS after 0902 and 0902 was pretty damn, ok, BIOS, if I recall correct at least in OC voltage sense how board acted up).

No worries mate I was responding specifically on that part of your post. And making it clear that you did not need to do anything else but use the EZFlash2 method.

No worries, just found the comment a bit odd, heh. I manage few and write few forums too.

Anyway, latest testing / currently system state at this post:

(Extra info over testing:
There's an odd POST stop I found when I finish WinSAT > reboot > ending up on blackscreen and PCIe light under Slot 1(PCIEX16_1) is up for good while. As for Debian - Linux well as for so far booted off GNOME on stick and seems can't find any informative software other than basic info and that doesn't say anything about speed. Will try again as soon I find some hardware info software.)

yeah, anyway..


-----------------------------

Flashed again to 3603 and pre-that with full CMOS reset. went to BIOS again disabled every single function there was. It seems that got rid of Intel device (HD4000), but speed is still x4 at AMD HD5850 (verified by copying data CPU->GPU, GPU->CPU 1,7G/s only and by other programs).

We have to start considering other alternative options, because you cannot just narrow this issue to BIOS software side.

Options:
* Motherboard - CPU pins might have an issue (dirt, what ever, although as by look of them they look fine.)
* CPU itself might be faulty (When you start sticking RAM controllers, Limiting PCIe lanes from users [x58] and sticking badly optimized Intel HD iGPU in the box which absolutely no one in this earth does nothing with where no support ever works even on processing level at some point faults will start happening I mean in worth case Intel GPU is taking the lanes).
* Hell, I could even bring this to OS level (because I do not have alternative system to test at USB clean up, but could be basically Intel PCI-Express drivers v9.x.x.x or even Windows simply having some permanent save mode up).

Facts:
Slot 1 (PCIEX16_1): Boots at PCIe 2.0 x4 (card telling OS that it is x16 capable)
Slot 2 (PCIEX16_2): Boots at PCIe 2.0 x8 (card telling OS that it is x16 capable)
Slot 3 (PCIEX4_1): Boots at PCIe 2.0 x1 at AUTO (Boots at PCIe 2.0 x4 when switched from BIOS)
(All unneeded devices / options disabled at BIOS)
Steps taken:
1. Updated through EZFLASH2 - BIOS 3603
2. switched I5-2500K -> I5-3570K
3. Booted up and PCI-Express switched to PCIe 1.1
4. CMOS reset + reupdate BIOS 3603 -> PCIe 2.0 x4 mode (slot 1)
5. As suggested by Forum: reupdated 3603 -> PCIe 2.0 x4 (slot 1)
6. Tested through all available PCIe Slot speeds.
7. CMOS reset + BIOS 3203 in currently -> PCIe 2.0 x4 mode (slot 1)

So, as we can see seems we cannot find this on software side unless indeed Windows is making this up. Going to boot latest debian next see what that says.

Intelligent comments welcome, "That is how you flash your bios correctly." ain't exactly helpful. You could of at least make an constructive comment like raising the CPU might help or cleaning fins with alcohol might help, slot might be damaged or perhaps give reference to secondary OS. Not to be rude, but just saying as a moderator commenting on post usually encouranging to constructive posting only.
