SLI help

[Groedius]

Disabled PhysX and ran 3D mark 06 once more got 9321.

 

Would appear that i am being bottle necked by my CPU and RAM ... Going to have to look into getting that upgrade ASAP.

[Rofltroll]

just a thought ... you sure the new card works? Did you try it individually? also what are your ram and CPU specs anyway?

[Groedius]

Did not try it individually but it would appear it is working but i could try it.

 

its getting old now i have an E6600 and 2 GB RAM looking to upgrade soon.

 

Also does any1 know with SLI some motherboards say they have 2 x PCI-E x 16 slots but speed is X 16 X 8 will that be considerably slower then a board that has 2 X 16 Slots.

in XP (32-bit) you will have a lot less available RAM by running 8800GTX SLI vs a single card

 

I'm going to guess (as you've not stated, nor added to sig) that you are running 4GB of RAM

so minus 768MB for first GTX ~= 3.25GB... then minus another 768 ~= 2.5GB

 

minus all other RAM requirements and it's a RAM-starved situation (which could affect your benches)

 

install 7 64-bit to free up your RAM, otherwise you are wasting ~1.5GB on SLI (by using 32-bit OS)

 

here's my best 8800GTX SLI result for comparison: 20992

Also, there are no problems with the 64 bit version of Windows 7... I doubt there are many people on this forum who even use the 32 bit version.

Okay I think i will try get my hands on a copy of windows 7 64 bit then and thats good as it has support for 2 monitors on SLI.

 

Also do you guys know if it makes a lot of difference in SLI with the speeds

 

Like some of them are x16 x 16 so would x8 x8 be twice as slow as that and they are generally cheaper boards so i should just pay out a bit more for the better boards which support dual x16 ?

Have you enabled SLI in the motherboard BIOS (depending on your motherboard)? I used to have this problem with a DFI Lanparty nF4 SLI-DR Expert (Nerm was too), until we figured out that you had to enable one or two options in the BIOS before anything SLI related was taking place!

What kind of SLI bridge are you using?

[Groedius]

Im using an ASUS flexible 120 mm SLI bridge.

 

I downloaded the BIOS update for SLI so i believe i have enabled it there. How would i be able to check this ?

[Groedius]

Okay so i am looking at upgrading and taking my cards in SLI to a new build my question is alot of boards have 2 PCI-E X16 slots but the 2nd slot runs at X8 does that mean it would be slower then in a board with 2 X16 or not because i dont think any cards can actually use the whole x16 yet ?
