Is this SLI set-up performing normally?

Is this SLI set-up performing normally?

GPU0: ZOTAC GeForce 9800 GT Synergy
http://pden.zotac.com/index.php?page...emart&Itemid=1


GPU1: POV 9800GT 1G HDMI DDR3
http://www.pointofview-online.com/sh...product_id=151


Mobo: P6T Deluxe V2

Monitor attached to: GPU1: POV 9800GT

Problems:
1) The POV 9800GT is running at DDR2
2) It is not using the full capacity of the GPU0

Below is a screen shot of the GPU/CPU while Testing with oZone3D:



Is this normal?

I'd say potentially no ... but not positively.

What does GPU-Z say for the memory speed on the PoV card? How about AB, when you're actually running a 3d app, what does the speed say in the graph? Does it crash out if you manually bump mem clock up to the speed of the other card?

AFA the Ozone app goes, two things to make sure of: 1) you're running in full-screen mode, as SLI can be flaky in windowed mode and 2) you're running the multi-GPU version of the app. I know with Kombustor there's two separate versions, one for multi-gpu, and one for single GPU. If you run the single GPU version of Kombustor on a SLI setup that could cause low (or zero) GPU usage on the first card.

why does the pov card say its ddr2 128bit and have less shaders? also you memory speed is slower

Yeah, that's what he's asking about

I'd be willing to be it's just nV inspector misreading the model of the card ... those specs look almost exactly like specs of certain 9600GSO cards.

Something to understand about apps like inspector and GPU-Z ... some things they show are based on what's in the bios, and some things it shows based on a database of the specs of different cards. By no means is everything you seen on the screen based on the application physically detecting specs, like whether or not your bus is 128-bit, and your memory is DDR3, etc. It relies on a database for most of it.
