Sli problem

Sycho · 21 Nov 2013 at 20:33

The slots you have in should be fine...just take 1 out of their current slots for a day to test with gaming then put back in the next day removing the next from it's current if the sli bridge and psu connectors do not solve anything.

From a pic on google your bridge seems upside down so hopefully it's the case....look here: http://i.haymarket.net.au/News/SLI-GTX-780.jpg

flipping it over has made no difference

I know this isnt particularly seen as any good but I did the windows assessment thing and got this

My old PC got better CPU/Mem scores than that :confused:

and that was one of the very first i7s @ 2.6ghz. Its supposed to be an extreme overclocked bundle. Says 4.6ghz in the bios but nowhere else

Have I done something monumentally wrong setting this up, is there anything I can do to check stuff? Sorry for all the questions its just this is so frustrating, spent a fortune on a new PC and at the moment its slower than my old one

You might just have a duff motherboard, this is my third motherboard in 2 weeks and the Force is a lot more expensive, ring Overclockers in the morning and go from there. I spent 2 days solid on my last motherboard as the onboard sound went off, re-installed windows on 3 different drives, just sent it back in the end and all was ok with this one.

Even if the cpu was at default you should still get around 2600 in Heaven 4, so it nothing to do with cpu or memory.

That doesnt sound good...

I bought an overclocked bundle though, build time was 7 days, surely that means it goes through a load of testing?

Can it be down to drivers you install for the board?

They will only test the cpu overclock is stable with the memory, the only drivers you would need are the Intel inf driver and the nvidia driver to run and test the sli.

You can check if there is a profile named OC in the bios, if there is you can load optimized default bios then try that, as long as that OC profile is there you can reload it back after.

Also check this
2 x PCI Express x16 slots, running at x4 (PCIEX4_1, PCIEX4_2)
* The PCIEX4_1 slot shares bandwidth with the PCIEX16 and PCIEX8 slots. When it is populated, the PCIEX16 slot will operate at up to x8 mode and the PCIEX8 slot will operate at up to x4 mode.
* When installing a x8 or above card in the PCIEX4_1 slot, make sure to set PCIE Slot Configuration in BIOS Setup to x4. (Refer to Chapter 2, "BIOS Setup," "Peripherals," for more information.)
(The PCIEX16, PCIEX8, and PCIEX4_1 slots conform to PCI Express 3.0 standard.)

Mine is different as it has 3x PCIEX16 slots running at x16

Last resort check this as you can turn the pcie slots off individually

Make sure that they are set right or it will only work with one gpu

It was on auto. Is this board not very good then?

zuludawn · 21 Nov 2013 at 22:25

Just check the pcie pins on the motherboard first as above, the motherboards are very good, just unlucky if we have had a bad one or two.

Mightyashy · 21 Nov 2013 at 22:31

looks like this

zuludawn · 21 Nov 2013 at 22:32

Ok same as mine just move the second gpu to another pcie slot and try that.

ok mate, appreciate the time you are taking to help by the way, just about stopping me from punching the pc

zuludawn · 21 Nov 2013 at 22:39

After make sure your first card is in pcie slot one and the Bios states

Mightyashy · 21 Nov 2013 at 22:52

ok bios looks ok

switched the 2nd card to the slot above so the cards are right next to each other and sli is no longer an option in the nv control panel. device manager shows 2 ti's still and the bridge is connected

zuludawn · 21 Nov 2013 at 22:56

Download GPU-Z from TechpowerUp and look to the right where the quetion mark is, this show the Sli and what speed they are running on the pcie, if you click on the ? it will run a test to confirm this

Sometimes you will need to re-install Nvidia drivers when you move the cards.

Mightyashy · 21 Nov 2013 at 23:31

This is both of them mate, did the test and it ran, just loads of squiggles and whatnot, with gfx card names bottom left

zuludawn · 21 Nov 2013 at 23:35

Okie did you re-install the nvidia drivers ? (there was a new driver in the last couple of days). If have go for it and benchmark Heaven 4 again. If you do a custom install at the bottom there is a option to delete all old drivers first.

yep, reinstalled and did clean install option. will run it now

FFS i feel your pain, re-install Heaven 4 , GPU-Z can see them so it cannot be the dip-switch. Download Cinebench and run OpenGL that, ill compare that.

ok mate, does it matter that im running the basic edition? assume not.

slightly off topic but was trying to check the cpu/mem and got told when running prime95 it would go up and reflect the correct overclock. did this...
