LGA775 INCOMPATIBILITY WITH UEFI GPUS

Hello to everyone,

I did a lil search and I didn't find similar topic so I started this one because I believe I m not the only one having such problem .

I have an ASROCK G41C-GS motherboard with the latest bios v1.40C, an ANTEC PSU of 550w and a gpu GIGABYTE GTX 650 TI BOOST 130W TDP that so far have been working absolutely fine.Yet i wanted to squeeze out   everything this system has to offer, so i bought a Palit GTX 1650 SUPER StormX 100W TDP.

I have tried everything i could (clean installs of drivers , installs through safe mode using ddu) ... Every time when the graphics driver of nvidia is attempted to install/load, the screen goes black loosing signal and it cannot be recovered. From what i read around the net it s a common issue with older boards not supporting uefi...Is there a way to go around this issue ?. I must add here that i have done the 771 to 775 mod using a xeon 5470 and i modified the 1.40c bios   adding the newest cpu instructions for those xeons   (2015 latest update) . That way the system works flawlessly , windows recognise the cpu everything works smoothly with the old gpu, so i believe this is not the issue. There s another board still being on the market , the G41C-GS REV 2.0 with newer oem bios than the original board ... could i use that since the 2 boards seem identical? ..Is there UEFI support or anyway support for the latest GPUS ? Spending 100 bucks to conserve power and bosst a lil bit the performance of my aging system is one thing ... having to spend few hundreds of euro to build a whole new pc is another thing especially in the current circumstances. Please consider that before you easily reply to me to go build a new system to fit in the GTX 1650 SUPER. GPUS should work in every board having pcie x16 and appropriate PSU power with varying performance ofc but still functional, since the manufacturers requirements for GPU are limited down to the PSU WATTAGE/available power connectors and a minimum storage space available NOTHING ELSE.

Thank you in advance

Unfortunately, that's just how things are with older, non UEFI boards. You can try
checking redit and other places for BIOS hacks etc but I doubt you will find anything.
The hardware is just too old, it is why certain used prebuilt systems (lenovo,
dell, hp etc) are not popular for cheap gaming builds, they do not support UEFI
and thus cannot support more modern GPUs.

Your best bet would be to pick up a used 4th gen intel i5 prebuilt for cheap and
use that, it will probably cost you around 100 euro or so. Otherwise, you are stuck
with the original GPU I'm afraid. Just do not buy a small form factor system
(mini PCs), they are cheap but they are often almost impossible to upgrade.

You can blame GPU vendors for this (AMD/Nvidia), they chose not to retain backward
compatibility with pre-UEFI systems. Then again, anything that needs UEFI would
be severely bottlenecked on a system without it anyway. I can see why they chose
not to convolute their VBIOS with redundant code.

I would not attempt to flash to the Rev 2.0 BIOS, it will almost certainly not
work, it is why they make revisions rather than just keep releasing the same board
name, it's because they are NOT compatible at a BIOS level.

If I were you I would return the 1650 super and either pick up a decent used
prebuilt (as I said above) and a used RX 570, the cost will be close enough to
just the price of the 1650 super.

For a new system, that is faster than your current one, you will be looking at
at least 200 euro or so.

Your existing 1650 super
Athlon 3000g
A320 board (for a super tight budget) or a B450 (for upgrade options later)
8gb of DDR4 RAM (2x4gb)

The rest of your components you could reuse. This obviously would be your best
option, you can upgrade to a much better CPU later if you go the B450 route.
Even with the a320 board you can upgrade to something like the soon to be released
Ryzen 3 3100 for $100 USD (so probably 100 euros). The 2 core 4 thread Athlon
will outperform your Xeon, use less power (by far) and allow you to play all
current games.
