What drivers are you using for both cards?
x1950 is a 'legacy' card... you need a 9.3 or older driver if you're trying to make both cards use the same driver that has both cards' dev id in the inf.

as the only driver that will work with mobility radeon HD2600 is the one from HP I had to leave that in there. After that I've unpacked the legacy AMD drivers and when I saw VGA compatible adapter in device manager I've tried manualy updating its drivers with the unpacked ones, but with no avail.

If I had removed ALL drivers and then used the older driver, would it work with both cards? IMHO I would have to mod the drivers with "mobility modder" so they could be used on mobility radeon.

Done. I've received all and I started the lab. I changed the power supply during the test, because when I started to use stress tests, PSU gone down. The GTX has many claims to watts on 12V rail .

Final (enthusiast ) configuration is:
PE4H-PM3N ver2.4 Package
850 watts PSU
GTX 580

Hi
I bought a GTX 590 and I put it in place of the GTX 580 but... does not work. I see two GTX 590 in different PCI address but with "error 43".

Can you help me please?

A 590 is basically 2 graphics cards in one, so you need 2 256MB windows instead of just one. You're going to have to remove/disable components to get the total 512MB free, if it's even possible. Also I don't know if Nando's setup program will try to make a window beyond 256MB.

On my laptop I cannot disable my internal card, but if i remove it, the system will boot with everything displayed by the 460 fine. If you can remove your internal card, try it to at least get some benchmarks for us to see!

I got a x220 with the PE4H (2.4) and a GTX460(1GB). As far as I understand the best performance is achieved by a "optimus install".

Downloaded Verde 275.33 + nando's nvam.inf (replaced it after extracting the drivers) and installed this driver. How can I see, if optimus is running? Right now there is no new menu or something like that.

What is better? Using the ports of the GTX460 or from the x220?

Got P3093 in 3dmark11 and 16-17k in 06. However BFBC2 has low fps (even at low resolutions).

Were those scores on the internal LCD or an external hooked up to the GTX 460?

You should see an Nvidia folder in Start -> All Programs. In there you can open the control panel for Nvidia and in the menu options enable the systray icon to monitor applications using the Nvidia card.

External with the DVI output from the GTX460 I think. Good/bad?

Sorry if this is obviously wrong, but is it possible to do SLI on 2 optimus links? lol throwing the idea out there.

I don't know about optimus, but you can do SLI. I ran this patch on my system and it completed successfully. No 2nd 460 to try it out though

Anyone know what value the intel.txt file in the vidock image should contain for sandy bridge motherboard?

mine lists southbridge as ID1C4F

thanks

EDIT:
replacing with 2GB memory, uninstalling "Standard VGA" device, restarting.
Still get standard vga on re-connect..

Ensure SW1 is set to position 1 on the PE4H 2.4+.
If necessary use the Video Cards.Initialize function in Setup 1.x to get rid of the error 43.

Two 256MB pci-e windows will need a very relaxed BIOS OR removal of RAM. If not sure please run Setup 1.x, choose Save Diags.compact_fails, upload the resultant contents of the \diag directory to mediafire.com and send the link.

It would actually be better to run 2xGTX580s, each on it's on x1 link (mPCIe + expresscard) to double the bandwidth. Would require SLIPatch to allow a non-certified SLI setup to work.

The 16-17k 3dmark06 benchmark results mean x1.1Opt is active. You want to connect the DVI/HDMI output on the GTX460 for best performance. Still, if BFBC2 requires a lot of pci-e bandwidth it may have low FPS. A workaround is to buy a ViDock4/4+, which claims pci-e 2.0 compliance. That will double your bandwidth. There's one on ebay ATM you might be interested in.

As noted before, with Sony VAIO E series, gtx460. allocation reserve problem , solution: memory must be 2GB.

Well, on the main page, Nando4 Said, only Nvidea cards can fit.

Does this mean i cant run Ati on my EB12FD? ( Location on the page:i-core... (use find))

I worked with a user on the E-series. We discovered the bios had hardcoded a device to sit in the E0000000 range preventing it from being a 256MB contiguous space. Fortunately a NVidia card use a fragmented 128MB+64MB+32MB BAR so we could allocate around the problem.

Please post your devcon.txt file so can see if your E-series is affected as well.

Devel version of Setup 1.x includes support for SB systems. Please use that instead.
