I consider myself a newbie, I have done very few builds, among them an X99 Asrock OC formula for a friend with a 4-way GTX 980 which went really fine and found the OC formula pretty capable in basic Auto overclocking. Anyways, I decided to go for a similar build, so this is a list of my hardware:
1. Asrock X99 OC formula E-ATX
2. EVGA G2 1600w PSU (Only for future proofing)
3. Intel I7-5960x
4. 4 x 4GB G.Skill Ripjaws 3000Mhz DDR4
5. Samsung 850 EVO 1TB
6. 4 x EVGA Nvidia GTX 980 (hoping for a 4-way SLI)
7. Thermaltake water 3.0 Ultimate AIO liquid cooler
8. LG Internal Blu-Ray reader/CD&DVD writer and reader
To cut everything short, everything was fine till the 3rd GTX 980 was installed, has been recognized in Nvidia control panel and Device Manager. Installed the 4th GPU and here starts the problems, I noticed the boot time is taking a bit longer than before, like 5 seconds more, then the dreadful message shows in the Device manager, “Device does not have enough resources – CODE 12” and It does not show at all in Nvidia Control Panel (Only 3 GPUs showing). I tried so many things, swapped all 4 GPUs, swapped all PCIe slots, swapped all VGA power cables, same result, the 4th GTX 980 is always with no enough resources
I Cleared CMOS, rebooted, F1 function to enter new Set-Up, Loaded UEFI defaults then F10 to Save & Exit and rebooted: Same issue. So, I cleared CMOS with same previous steps and re-installed windows: Same problem remains, but I noticed something two strange things that might be useful in solving this mystery:
First thing: The Mobo has 4 switches that control the 4 PCIE x16, when I disabled the 4th switch, it completely disabled the 4th Graphic Card (no power, no LED, nothing) which what it supposed to do but It somehow disabled PCIE1 with the video output because there was no video output whatsoever all the time when the 4th switch was turned off. The GPU plugged into PCIE1 was still on and running but had no video output from neither HDMI or DP!!
Second thing: In device manager – although I am no expert – 2 of the GTX 980 cards had the same slot number, so I click on PROPERTIED and this is what it says :
GTX 980 # 1: PCI slot 0 (PCI bus 4, device 0, function 0)
GTX 980 # 2: (the one in question): PCI slot 6 (PCI bus 1, device 0, function 0)
GTX 980 # 3: PCI slot 0 (PCI bus 2, device 0, function 0)
GTX 980 # 4: PCI slot 4 (PCI bus 3. Device 0, function 0)
Slot 0 is occupied twice? Anyways, after some experimenting, I know now that my system assigns “Slot 0” to 2 PCIE slots, #1 and #5 (#3 is a 2.0 and is not used in 4-way SLI set-ups, so 4-way cards are installed on PCIE 1, 2, 4 & 5 on the X99 OC formula)
Please help! Is my Mobo faulty or is it a software thing? I haven’t been sleeping for 2 days, staying up experimenting, because of this damn system!
