couple of questions

Hi,

I've a couple of questions I could do with answering.

I took delivery of 2 8800gt's today, fitted them on to my A8N-sli deluxe mobo and started it up.

While in SLI should I see 2 8800's in the device manager list or two? and if I plug a monitor in to the second card should it get a picture?

Secondly, anyone know why fitting 2 new cars would stop the network card driver from working?

My GTX295 shows up as two devices.

Is SLI options available to you in the Nvidia control panel?

I can't see any, i'll have a go at taking it out and refitting it

Its called "set multi GPU and PhysX configuration"

You put the SLI bridge on these two cards?

power into both?

AHarvey · 19 May 2011 at 02:32

Ok, under the nvidia control panel I have Physx options, but under 3d settings with no sign of multiple gpus. Even in the Physx option it only shows 1 card.

SLI bridge is on both cards and both have power.

Nvidia graphics driver is 270.61

I have loaded up the BIOS and there is a section in there on SLI:

ez-plug warning = enabled
SLI Broadcast Aperture = auto
AI-Selector = auto

the odd thing is, that if I remove the card from the PCI-E 1 slot and just leave one in the second slot, it doesn't matter which card it is, upon loading up windows there is no Nvidia control panel option.

I am starting to think its more motherboard or driver issues.

Both cards work fine in PCI-E 1 slot, just the second slot there is issues

Mother board A8N-SLI Deluxe + Win 7 64

Downloaded the manual for my motherboard, seems there is a Asus EZ Selector card on there.

I've now turned that around and set it to dual cards, and booted up, didn't work.

Set the option in the Bios to "AI-Selector" to Dual to match the selector card, still nothing.

Next step, updating mobo drivers if any work with win7

Just had a look at the manual.

On page 168, it says you should plug a 4 pin ATX power cable into the socket called E_Z PLUG on your motherboard, otherwise your system will become unstable. Have you done this?

Vista 64bit drivers should work.

Sorry, had to grab some sleep

Yes, there's connector attached. You get quite a loud continuous tone if it isn't or the gfx cards haven't got power connectors attached.

Going to try some motherboard drivers today as I know none were installed with the new install, then look at flashing the bios to a newer version. :S

SORTED!

opened control panel and checked out the device manager. Had a VGA controller in 'OTHER DEVICES', just right clicked and told to update drivers, let windows do its thing and now showing the other 8800gtx.

Nvidia control panel hasn't got any options for SLI, however it is also showing both cards under the physx panel

stulid · 19 May 2011 at 15:44

You sure?

And there should be an option in the "Manage 3D settings" to allow you to adjust the Multi-GPU rendering mode?

AHarvey · 19 May 2011 at 17:12

Nope, this is all I have:

nvidia control panel version 3.6.750.0

Checked under system specs from within the Nvidia CP and both cards are there with the same details apart from card 1 is showing:

BUS: PCI Express x 16

and the second card is showing

BUS: PCI Express x 1.

I am guessing that although its seeing both cards, SLI hasn't been enabled

Thanks for the help, I really appreciate it

On the 3d settings tab along the top, two options,

Show Multi-GPU visual indicator.

Show PhysX visual indicator.

Games will have a green line drawn across them showing the loads across the cards.

stulid · 19 May 2011 at 17:19

Just read the spec of the board,

2 x PCIe x16 *SLI mode : x8 , x8 *Default(Single VGA) mode : x16, x1

It sounds like SLI isnt switching on if you say the second pci slot is at 1X speed.

AHarvey · 19 May 2011 at 17:56

Rebooted, went in to the bios settings and changed it to dual cards instead of auto, and it only showed one 8800 at x8. Rebooted again and reset it to auto, 2 cards again showing x16 and x1.

And under 3d settings tab I only have the show physx option.

Starting to fry my noodle now! Got to go paper and ceiling, will try and see what else I can do after, other wise i'll just have to run it with one card!

Thanks again

Replaced the chip that you had to switch on the mobo with a spare I found, now it works and Sli option in the nvidia cp

Thanks for the help, very much appreciated

Now to test it and then upgrade the ram and then save for a new PC all together
