GT 1030 and GT 520 in one PC.
Hello,
I want to use the GT 1030 as main graphics card/gpu and the GT 520 as an HDMI/audio solution to try this out. So I stuck the GT 520 into the PC as well. It has two PCI express ports/slots (winfast motherboard NF4SK8AA (or similiar)) Windows 7 ultimate edition 64 bit is not detecting the GT 520 at the moment.. Only the GT 1030 is detected and working with installed driver. The installed driver is currently: 417.35-desktop-win8-win7-64bit-international-whql-rp.exe (Older drivers are available online and on my system, however they contain some security issues). I have run two 7900 gtx cards 512 mb in sli mode in the past but these got to hot. These only required a single driver and was easy to setup. The current experiment is not so much about increasing graphics performance but using graphics cards for different purposes. It could also be handy for dual-monitor setup or cuda debugging. So it would be nice if the current driver would work for both graphics cards. However perhaps this newer driver does not support GT 520 anymore. I am unfamiliar with how to setup multi-monitor/multi-graphics cards solutions. Would windows normally detect both graphics cards out of the box ?! Or does it require special driver installations ? Does it require "two graphics drivers to be installed or just one" ? Also perhaps I need to disable something in the bios, perhaps SLI ? Or perhaps I need to tweak some setting in bios. Or perhaps I need to fall back an older driver to make this work, but that would rule out this experiment cause I don't want to risk security issues via browsers/opengl/webgl hacks and such. Very maybe a reboot might help but I doubt it. Any ideas how to proceed and diagnose the problem ? I am kinda surprised that windows 7 doesn't auto-detect the GT 520 usually it would detect at least something. Perhaps it's a winfast motherboard issue ? Unfortunately I cannot really try an other operating system at the moment cause of bad cd/dvd drive. This is a lesson learned though. It's usefull to install multi operating systems though when buying new computers in case "external boot devices and such" fail Though I am not a big fan of multi-boot and such... bit risky also to run linux on my harddisk for example, so for now... hmmm rather not.. Fortunately newer hardware has all kinds of boot options (for now) but useless for me for now... I tried booting from flash sd but I don't think winfast supports this unless a bios update or something is done... this would need new bios firmware which doesn't exist as far as I know. I also "invented" a nice trick while cleaning my pc to install second graphics card. I use a little soda-stick... which is normally used to suck up coca cola and such... and attached it to my vaccum cleaner to suck up dust from hard to reach places ! =D Quite an invention... will google later if a more mature device already exists lol... I would expect so =D LOL. Please advise with any advise you can give to get this second graphics card working on windows 7. Bye, Skybuck. |

GT 1030 and GT 520 in one PC.
I installed the last supported driver for GT 520:
391.35-desktop-win8-win7-64bit-international-whql.exe As far as I can tell this did not solve any problems yet. The GT 520 is not showing up. At least now a driver is installed that should be able to support both drivers. For now this is worthy of an experiment. However it seems more like a hardware detection issue. One thing I can think of is swapping the graphics cards. Perhaps somehow the GT 1030 is detected first and some how disables the GT 520. But first I will try a re-boot and see if there is anything in the bios that might be causing the GT 520 to not be detected. Bye for now, Skybuck. |

Hmm it seems to be a winfast motherboard limitation, which I find kinda odd, in the manual at page 27 it says the following:
"In normal mode, only the PCI Express x16 slot near the CPU can be used for PCI Express x16 graphics cards." So strangely enough this motherboard DOES support SLI... but when in "normal mode" it can only support one graphics card ?! Why the hell would that be ?! So weird ?! Well this summer I plan to build a new computer... waiting for computex and ryzen 3 announcement... and then some analysis... hopefully it gonna be good. Now that my widescreen monitor/dvi died and I am enjoying this vga monitor... I could unplug the gt 1030 and instead use the GT 520... since the GT 520 does have vga connector and hdmi too... So I could re-use the HDMI for HDMI output to see if it makes a difference when gaming compared to creative labs soundblaster. I find that experiment kinda interesting... not much point cause I do play on low audio in wows... but still even with low audio some difference might be noticeable. I think it's the CPU that mostly bottlenecks WOWS (world of warships) and not graphics cards... though I could be wrong... probably both bottlenecking a bit... But not that much difference between a gt 520 and gt 1030... though it was also worth an experiment... Brutal Doom runs really sweet on the GT 1030 though =D Bye for now, Skybuck. P.S.: Have to do some re-building lol. |

You have a paddlecard motherboard (NF4SK8AA)
The very end of your manual, has an appendix showing the paddlecard between the two video slots. With paddlecard you mean the "sli bridge board" ?! If you have two video cards plugged in, the paddle card should be in SLI mode. That ensures each card receives x8 of lanes. That's the x8/x8 mode but is also known as "SLI mode". Ok so if this is not installed, does this mean one slot gets nothing ?! Could this explain why the second is not working/detected ? OR would it get 1x pci, cause in the latter cause that would mean it should be detected but it was not. Actual SLI requires one of two things to complete the installation. 1) A ribbon cable that runs between two similar cards. This is the old way of doing card-to-card communication. SLI BRIDGE BOARD ?!? 2) A method that came out later after the invention of SLI, was "PCI Express slot to PCI Express slot" communications via the chipset bridge. One card would in effect become a bus master and "talk" to the other card. I presume the chipset has to decode these accesses properly, for the two cards to address one another. SLI BRIDGE BOARD. You missed something though, I also just saw it for first time... Some kind of bracket to keep the sli bridge in place ?! Kinda whacky/odd... I wonder if it would fall of if it's not installed. Not sure if I have this bracket... I guess it's in the box somewhere. ? If you don't do (1) on your system, it's quite possible that SLI won't happen in that case, because (2) is missing. SLI is for dual-use of graphics card... using both to do one task ?! Can't it bring both cards alive and use them seperately ??? Hmmmm... Mysterious. Thx for the tip though, maybe some day I try this out. Make sure the paddlecard is in "SLI" mode, then power the system back on and try again. Hmmm does it have any switches on it ? Hmmm... Use anti-static precautions when working with the paddlecard (wrist strap). At the very least, bring yourself to the same electrostatic potential as the computer case, before flipping the paddlecard around and back into its socket. Hmmm... Bye, Skybuck. |
