[Help] 7900XTX Sapphire Reference Card - 3 Monitors

[Bonse]

Afternoon all,

This is driving me mad, i've been running this card since Day 1 on 3 monitors, it's ALWAYS pulled 120W idle due to the Vram not downclocking, research at the time said that they were gonna fix it on a driver, still no fix.

I put some research in again as it makes my room so ******* hot even when just watching youtube or whatever whilst working, this research said it could be cables, some cables are **** and tell the card to throw as much at it as possible just for compatibility issues, i update my cables to some decent DP2.1 ones from UGreen. Same problem.

More research, they then go on about changing the blanking rate, i went through this method and makes ZERO difference.

I then think, maybe it's pulling too much data, so i lower ALL off my 1440p monitors to 6bpc, 1440p @ 60 - as this should pull less data from all 3 than my main monitor on its own running 10bpc, 1440p @ 240hz. Same problem.

It literally means i can't have a third monitor connected if i dont want my GPU to be used as a storage heater, let alone the extra £2/week its directly costing me.

Anyone have any dealings with this? I'm sick of it in all honesty.

Help is greatly appreciated.

Do you need all three monitors connected to the graphics card? Using the IGP could help you to avoid the problem, assuming your CPU has one.

Honestly, no is the answer, but ive had 3 monitors for the last 10 years lol. I have a 9800X3D, it has no IGPU.

I was honestly contemplating selling it and getting a 4080/4080S or see what happens with the 50 series upgrades

Id hate giving my money to nvidia though

The 9000 series all have very basic iGPUs, which you can use if your motherboard has an output connector for it among the rear IO. I use the one on my 9950X3D to work around this very problem with my own 7900XTX.

Oh **** i knew the normal chips had igpus, i thought they removed them with the X3D, i'll defo give that a go

Works a treat, thanks. No idea why i didnt think it had an iGPU... sorry guys
