(mine the box is black)

everywhere i looked i saw this board have 2 pci16x by 8lane,even on the jetway website.
i carefully read the user manual that i downloaded on the same site,it says the second pci is a 4 lane.

if someone can help me with that i may avoid a frustrating experience.

The list in the download user manual, which one is your model, since I can't find any HA12 there....

Seems like they have just one manual the HA12-F... will check it and get back to you.

answer:
x16/ x4

me personally would sell or give board back and look for a board that at least runs x8/x8.
my opinion.

If you have that board on you, I would suggest trying to fool around with the BIOS settings for PCIe.
The heading says PCI Express Configuration
The, the other settings are very interesting, there's a DUAL slot configuration
and then you can , I think adjust the speed for slots 2 &3 and 4& 10 these are paired.
And the value says "Gen 2 High Speed Mode, Link ASPM and Link Width.....
With some luck, you might manage to get a Dual GPU setup run at 8x 8x...
Check page 31 of the Manual for the whole thing....

If that is not possible, then I'm afraid you'll be stuck with one 16x and one 4x PCIe Slot..... and there's no advantage in Crossfiring those two....

you can still have all the fun, just a few frames less than if you had a x8/x8 board or better.
play on..
I had a Jetway CFx board but it ran x8/x8, it was really a solid board.

I told you it will run and the frames your missing aren't that much..
my old Jetway board:

don't mess with those at all.
just leave the settings default in the BIOS and enjoy what you have.
hear of the phrase, "if it's not broke then don't fix it.?"
it's not going to make much difference.

yep found that,it donnot seem to imporve my kombustor score

It's not supposed to be improving anything You just need to check if it will allow you to insert a PCIe card in it and function @8x instead of the advertised 4x....
If it does, then you can go in for a CF setup later....
You forget about the scores on benchemarking programs for now.
What we are trying to do is work on the question that you'd asked and they way to go about it.... not the "I told you so BS" , you already know what the mobo manual says, now we're trying it practically to see if we can find a way around

I would like you to describe the setup which you have now, what all have you put into which slots on the mobo.

sorry mistype about pci2 i tried 8x,4x,auto

so is it running x16/x4 or x8/x8.?
I say x16/x4 only..

because it's only a x4 board for that slot..

that could be a heat issue as well as drivers.

troubleshoot drivers first then.

rechecked still x4
obviously this bios feature maybe for some other ha12 (ha12gt or lf)

OK
it you have set it to 8x for both right?
if you have Everest ultimate edition just check in that too if it shows the PCIe as 4x
This would be the last confirmation.....

just done it 8x 4x

i note that even when i set 16x for the first pci and pci2 in 4x,gpuz and everest both say 8x 4x.........i m fucked up

it do not seems to be the latest bios,i look into it.

so i ll go for an intel i5 2500k as my 955 is too short to run my cf (cpu 100% use whille gpu s are around 50%
obviously that mobo is 8x8x and not to expansive

is that one ok?
i know its out of the topic but seem logical to pursue here.

i hadn t plan to buy this ,i thought the upgrade i was planing was good enought,but this mobo is real ***,i have bsod everyday since i have it,for the more my 955 be make me awfully lag when in cf and when not it lag a bit .my old gigabyte am3 is now in my wife computer so no way back to my old rig
i cant stand having this 5850 sleeping in its box while i m laging
i m tired of having a computer that s not providing me what i want,i decided allocate some money to it(i would have been glad to use it for anything else like fixing my car or holidays).

so no comment about the board mean its a good choice?

ill be offline till monday
