PCI 2.0 x16 running at x4 even at load??

jayantfordreams · Mar 11, 2016

i'm using ASUS STRIC OC $GB 970 on a pcie x16 2.0 slot
Gpu z hows it as running at x4 even at load why ?? see the screen shot
i Checked MOBO settings is there i'm doing some thing wrong, its MSi z87m-g43 mobo
yeas i now it has a pcie 3.0 but for some reason i can only use pcie 2.0 s.
pls help.

Jay, please create your system specs please.

Is your card in the first slot because you have a PCI-E 3.0 x16 and a PCI-E 2.0 x16 @x4.

See my fantastic Paint job.

little cat · Mar 11, 2016

Try the PCI-E slot which is close to the CPU socket

Well as i said it's in PCIE 2.0 slot the second one, because of my stupid cabinet/case and this gpu is too long, Can't i run it on PCIe 2.0 x16 as per the manual if both lanes are x16, What performance drawbacks i'm gonna get with it??

i can't move it there because of stupid form factor of my cabinet...

If you go here: http://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/21.html, you'll see data on how it all affects performance.

EarthDog · Mar 11, 2016

Your slot is 16x PHYSICAL, but its a 4x electrical I believe (go to newegg, find your board and look at the back of the board. Notice the little metal 'pips' are do not cover the entire slot?). That is all it has to give boss. Time to get a new case if you don't want to accept the few % performance drop.

Get another case . PCI-E 2.0 running at x4 is not very good

Edit : Cant You remove some drive cages ?

Depends on the game. Overall it pobably won't have that much impact.

dorsetknob · Mar 11, 2016

As @EarthDog says above
your putting a Graphics card into a PCIx 16 slot that runs at 4x your get no more performance than the slot is capable of delivering and that is 4x ( thats your lot for that slot )

it's nearly 13% performance loss for 1080p

Bad loss .

If you read on further into the conclusion, it could be even worse... depending on how the 4x slot is wired through the board (it's either direct to the CPU ...good, or through the chipset ...bad). My guess is through to the CPU with the Z87.

Edit... or maybe not (see the middle left PCIE 2.0):

See the above link , when i installed this gpu i removed the cased below 3rd level, is there a way to remove case at 3level [looks like old floppy thingy case ]

For a GTX980. And again, depends on the game. Ryse is really hammering the stats up there, others differ just a few FPS.

EarthDog · Mar 11, 2016

He has a 970, the difference between the two won't be much as their throughput is similar.

In most game @1080p 970 is only 7% average slower than a 980 like 5-7FPS difference consider vmem uasge > 3.501 GB

m&m's · Mar 11, 2016

The card is 280mm long and the case can accommodates cards of 281mm with the cages. If it doesn't fit it must not be by a lot, just bend or cut a little bit of the floppy cage. I mean it's not like you're going to use it.

little cat · Mar 12, 2016

Cant that floppy cage be removed ?

lonewolf · Mar 12, 2016

Pic does not show it but there should be some rivets or screws you can remove to eliminate the floppy cage.

I believe the top floppy/3.5" cage and 5.25" bays are all one piece of bent metal. You'd have to dremel it out, and then it would really make the 5.25" bays weak. My suggestion is to just get a better case.

Should be last resort . For instance Corsair Carbide 300R

brandonwh64 · Mar 12, 2016

Before I resorted to using a 2.0 x4 slot I would have cut out that part of the case.

jayantfordreams · Mar 12, 2016

Thank You all, for replying.. I finally fixed it, i cut that case by 1/3rd of it's original length, gave me nearly 3 cm space using a handy hand saw, similar to a jeweler's saw, saved me few bucks, now i can use both that case as well as my gpu sitting in right PCI-e Slot 3.0 x16,
Adios..
