Question XFX Merc 310 - - - black screen after bios splash-screen on X58 motherboards ?

[bohemond1099]

So pretty righteously pissed at this point; same issue on two X58 motherboards (EVGA SLI/i7 920 and Asus Rampage III/i7 980X); black screen after bios splash; dispayport does not work at all and I have to use hdmi to get to bios screen; after bios however, black screen and windows never loads. For the EVGA board this occurs if I try to go to save mode to uninstall the 7900XT; for the Asus board I can never get to windows to install the 7900XT. Previous AMD cards (HD 6970/7850/7950/7970/R9 290X/R9 390/R9 Nano/R9 Fury/RX 480/RX 580/Vega 64)) work fine on both systems without these issues; also no Nvidia card I own has cause this problem; I have tried GTX 580/680/770/780/780Ti/Titan/980Ti/1080Ti/2080Ti/3080Ti and never once have had this problem. Anyone run into this and have a solution; thanks

I would imagine the AMD driver package has something to do with it. Do understand you're massively bottlenecking the 7900XT with either of those CPU's even if you do get it to work. I had a 9700K when I bought my Merc 310 and after upgrading to a 7800X3D my FPS almost doubled in most games. You're probably even bottlenecked by the PCI-E slot. The 7900XT is a beast of a card.

Even my i7 920 can get over half the performance in games as my i9 10920X and i7 10700KF systems @1440 for gaming; so was wanting to use my i7 980X which has much higher clock speed with this card.

You can extrapolate the performance loss by using the legacy CPU charts and the new ones. Even the 10700KF is a bottleneck. By probably 60-70 FPS compared to current CPUs. Bottlenecks used to be more talk than real but they are absolutely a thing now. I was shocked by how much of an improvement I got going from a 9700k to a 7800X3D.

Tomorrow I will help research as I to love these old 1366 systems myself. Before I go I have seen the Nvidia 4060 run on our old boards. No not saying go get Nvidia just saying there might be a fix to get that AMD 7900xt going. Can't say for sure till I do some digging tomorrow.

No; that's a marketing myth done via not using max settings; once you max settings the cpu advantage drops massively; if you're playing 1080p with just high or base ultra yes; but if you are maxing settings 1440p on up those canned marketing benchmarks start to show holes. That is why even an i7 920 can get 55FPS average across 20+ modeen games at maxed settings with a 1080Ti an kepp showing scaling to current cards like the 7900XT.

Basically any i7/Xeon 4c8t+ CPU since 2008 is plebty for gaming and will show scaling even with current GPUs . C2Q is where you hit a more hard cap; but not Bloomfield. But for modern pc games even a C2Q can do many AAA titles. My QX6700 and Q9650 sure can.

But anyhow that is all irrelevant to my post; my post is about AMD 7900XT having varying issues with X58; on ASUS Rampage III Gene black screen after bios/post and on EVGA X58 SLI; same issue if attempting to go into safe mode (but works fine if you stay away from safe mode).

My 3080Ti FTW3 with 3x8pin vs the 7900XT 2x8pin has 0 issues booting on both X58 system.

The top video at least shows up to the AMD 6900 can and does work on a 1366 platform.


I have just gotten a chance to look but bottom link even on a much newer intel platform having issues.

There is not much info out there on the 1366 platform + the 7900 XT

RX 7900 XT no display output in main pci-e slot.

I recently purchased an rx 7900 xt, my first amd card, only to have half the performance it should. I first put the card in slot 1, no signal but fans spin. On board graphics still work and no gpu is detected at all. If I put it in slot 3 which is the nest slot down on my mobo, it works and displ...

I am playing at 1440p max settings including ray tracing in many titles which the 7900XT does quite well. 144hz monitor. The almost doubling of my FPS going from an i7 9700KF to a 7800X3D was not a myth.

I'm almost sure the new AMD cards no longer support older hardware. I'm not sure if it's driver level or BIOS or even a hardware incompatibility though. If you want to buy a card that's massively held back by your current hardware that's fine by me. But I'm speaking on 1st hand experience not some marketing hype.

Driver compatibility would definitely be a factor. At some point, manufacturers do have to stop supporting older hardware. Using a 2023 GPU on a motherboard from 2011 / 2012 would definitely be considered bricked. And it's mainly due to the lack of driver support on the hardware manufacturer's end. Plus you also have to consider things like power delivery and the number of PCI-E lanes your motherboard has. A 10+ year old motherboard would surely lack the necessary PCI-E lanes needed to support a current, high end GPU such as the 7900XT. Sure, theoretically you could use that Merc 310 on a 10 year old motherboard, but at this point it would be like putting a Ferrari engine in a Ford Focus. You could, but should you?
