New video card with ASUS Z87-PRO works but 2nd video cards no longer work

Tags: Hardware

Hi.

System details ..
Mobo: ASUS Z87-PRO.
CPU: Intel Core i7-4770K CPU @ 3.5GHz – x64-based.
RAM: 2x 16GB Kingston HyperX paired – 31.9GB usable.
Power: 1200W.
Disks: No disk changes, with system disk 3.63TB free.
Op Sys: Windows 10 Pro v21H1 Build 19043.1889 64-bit.

Monitor details ..
Mon 1: ASUS VS228H-P is my default monitor.
Mon 2: ASUS VS228H-P.
Mon 3: ASUS VS228H-P.
Mon 4: Samsung 226BW.

Initial graphics cards and monitors ..
1. Nvidia GeForce 8800GT in slot PCIEX16_1 attached to Mon 1 & Mon 2 both using DVI-D.
2. Nvidia GeForce 8400GS in slot PCIEX16_2 attached to Mon 3 using DVI-D & Mon 4 using VGA.
The monitors are in Windows 10 extended mode.
This works perfectly.

Planned graphics cards and monitor connections ..
1. EVGA GeForce GTX 1650 Super SC Ultra Gaming, 4GB GDDR6 04G-P4-1357-KR in slot PCIEX16_1 attached to Mon 1 using HDMI & Mon 2 using DVI-D.
2. Nvidia GeForce 8800GT in slot PCIEX16_2 attached to Mon 3 & Mon 4 both using DVI-D.
The Nvidia GeForce 8400GS would no longer be used.

I installed the cards in their slots and installed the latest driver for the EVGA card, and Mon1 & Mon 2 worked as expected.

However, Mon 3 showed ‘DVI no signal’. Mon 4 gave the alternating ‘Analog’ then ‘Digital’ message followed by ‘Check signal cable – Digital’. Both DVI-D cables were installed correctly. The Q-Code settled on A0 just as before the change – no component LEDs stayed on.

To test whether the issue was with the slot and not with the card, I replaced the Nvidia GeForce 8800GT card with the 8400GS and changed the Mon 4 cable to VGA. Mon 3 showed ‘DVI no signal’ as before and Mon 4 gave the alternating ‘Analog’ then ‘Digital’ message then no message and a blank screen. Same result as before. The Q-Code settled on A0 just as before the change – no component LEDs stayed on.

It seems that the installation of the EVGA card is somehow preventing slot PCIEX16_2 from working.

Can you explain what I’ve missed or misunderstood, and how to solve this?

I appreciate your help. Cheers.

Frankly I would never mix old PCIe video and new

The new 1650 is the newer EUFI PCIe card and as such will need the usual EUFI BIOS and whatever settings the maker calls out. A fine test to see if you have that correct is to use only the 1650 and get a BIOS screen up. We don’t need to get to Windows yet.

This also means an awful mix of new and old Nvidia drivers. It may be unsupported. In other works, I would never mix EUFI and non-EUFI video cards.

No solution offered, just pointing out that EUFI video cards can do what you are seeing.

Is the BIOS EUFI capable and set to use such?

Thank you rptoffitt. I couldn’t find out whether the EUFI was capable. So I connected Mons 3 & 4 to the Asus mobo’s onboard DVI-I & VGA, checked that its latest driver was installed, and the monitors work just fine. So I’ll remove the 8800 now. I also learned that the EVGA driver doesn’t support the 8800.
Cheers.

There are so many discussions

About pre-EUFI setups also called “BIOS” and/of CSM that I can’t repeat all that.

So, for BIOS and CSM setups I know to stick to non-EUFI video cards which for the most part you’ll encounter models before and including the GTX 10×0 line. Once you go past the GTX 10×0 models you find video cards that just won’t play along on older BIOS based PCs. I had a rather nice TANK of a PC from HP called I believe the d5000t with quad core 2, max RAM, SSD and GTX 970 but it would not even try to boot with a GTX 1650 or 1660.

I’m not sure I’d call it a PC as it was more like a tank.

The ASUS Z87-PRO uses a EUFI BIOS ..

I know what you mean about tanks. Had one of them for years that I built. Great rig till it started crying so I built the next .. and the next .. 😉 Looks like it’s time to repeat the exercise. At least I’ve got an up-to-date graphics card even if it’s not the latest.

And is the BIOS set to secure boot, EUFI and the HDD in GPT?

In reply to The ASUS Z87-PRO uses a EUFI BIOS ..

If it does have EUFI, during the changeover from BIOS/CSM you would see machines setup to CSM/BIOS vs EUFI and then once in a while the EUFI bios was broken. You would have to update it and if the GPU still wouldn’t show up you call the motherboard maker for more details/ideas.

But still, I haven’t seen mixing very old and new cards to work well because of driver support issues.
