How To: Enable SLI on pre-i7/i5 hardware

[Nick [D]vB]

it's too bad.

I am starting to think that god does not want me to test SLI

I can't believe I was so stupid not to remove that bloody midi cable...

Did you look at the photos? It must be the worst SLI PC on this forum lol

The card was only £30 so it's not so bad, I will borrow another card soon to test with.

After all this I really hope rev.4 can work now, I'm really looking forward to trying it.

What were you testing in the "experiment" you did this morning ???

 

[Amarantine]

fast and simply method is system restore

unfortunately it didn't solve the issue too , because the oldest Restore point was October 2nd 2009 which is the date after the problem occured.

any ideas?

SLI will work only on x8+x8 or x16+x16 platforms

i know it now for sure

boot from CD/DVD and restore system

Then I have a big problem, I am stuck on x16 + x2, unless you have fixed it somehow ???

@Amarantine: http://www.avast.com/eng/bart-demo-request.php

Make boot disk on another PC, then use file browser and rename C:\WINDOWS\system32\hal.dll.bck to Hal.dll

exactly and you will be first with such platform. too bad. i wanted to get know results today...

Me to! So there is code in the driver that actually checks the PCIe speeds?

Also I have just found that my friend has 8800GTS not 8800GT! But if it is 512Mb I can flash it to work ok.

boot from CD/DVD and restore system

i told ya i did restore ma system to 2/10/2009 which is the oldest point i have.

is there any difference if i boot up from DVD then restoring ma system ? are there gonna be the same Restore points that i saw inside windows?

@Amarantine, if you have a Vista install disc?

1.Boot up the computer with Windows Vista installation DVD.
2.Choose Install.
3.At the screen before you’re asked to input product key, press Shift + F10 keyboard shortcut to open command prompt.
4.Change directory to the C:\WNDOWS\System32\
5.Then "del hal.dll"
6.Then "ren hal.dll.bck hal.dll"
7.Reboot

 

[Amarantine]

ok Nick i'll give it a try Right now...

 

[anatolymik]

yes

 

[Nick [D]vB]

So you can disable this check? Did you try running cards at x2+x16 yet? You could use the "sticky-tape" trick to drop the speed.

i know it now for sure

On my Abit IP35ProXE SLI was enabled at x16+x4,
but performance suxed but SLI was enabled.

i haven't tried. i have no means. but you can try.

maybe x2 isnt supported

 

[TheWolf]

Probably not.. Plus note my Shader count on the 2x260 192 & 216.
This could have had something to do with the low benchmarks I saw.
The SLI benches were below running a single card. I didn't do a lot of test on that rig.
So those may could have been improved.

I tried taping both cards down to x2 before (with old mods), it did not work but single card performance is fine, only lost 1-2fps is Crysis.

I've tested 112SP+128SP G92s before and performace was ok, I think 2nd PCIe slot on P35 is connected through the southbridge, maybe that explains it?

BTW this was done in XP 32bit with the modded driver, not halmod.

i tried x2 link width on my system = SLI not work
when i tried x8 link width = SLI works

Later on I plan to test the Abit AB9QuadGT its a P965 chipset.
I just want to see what happens with it.

Did you ever try hitting F8 key just before boot of windows?
Pick: Last Known good Config?

Yea I've Tried it before many times and the last time was today a moments ago , without any success it also unable to startup windows under any mode.

Do a repair install of the OS.
Boot from the windows CD, go to the point of a install & there should be a chose
to pick a fresh install or do a repair. Not a command prompt repair go past that point.
Then you shoulds see another chose of a F6 for repair. Or is it press R for repair, been awhile? lol
