Hi guys,
I have an very old card and I would like to repairing this.
This is a Sapphire Radeon HD 4870 1GB DDR5 card. p/n: 288-20e85-130sa

The gpu came to me with some misising parts, which I replaced.
After that the gpu as secondary is showing at linux and windows but won't give picture.
The GPUz shows a very strange information as you can see on the picture.
According to GPUz the gpu has 4GB memory...

In my opinion that the resource of problem maybe the gpu memory.
Could somebody help me, how can I test the memory?
I use tserver pack for newer gpus but I dont know what can I use for this old card.

If you have any idea please share me.

Thank you.

Ha nem telepiti fel driver akkor GPU-Z hulyesegeket fog kiirni, vagy is a rendszer memoriat fog megjeleniteni.
Az ATI/AMD oldalon megtalalhato egesz oldalni leiras arrol, hogy melyik regi kartyat tamogatja windows 10-et
Magyarul vagy kidobot a szemetbe, vagy telepited windows 7 es a hozza valo catalist driver, mas kulonbe orokre ott fog viritani eszkozkezeloben "nincs telepitve illesztoprogram", vagyis driver.

Uppsz erre nem gondoltam.
Este beteszem egy Windows 7-es gépbe és megnézem az eredményt.
