As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
not sure if it was the map or just the time of playing but i first played 40min on golmud railway without a problem and after that the map changed to zavod and within 10min my memory was full.
guess i have to give up hope and just leave bf4 for what it is and go play other games that are actualy worth the money.
Update 8: A new patch is out. (30. January). Problem still persists = it's not fixed.
Since AMD thinks each game patch fixes their driver problem, report the problem here: http://www.amdsurveys.com/se.ashx?s=5A1E27D25AD12B4F - you can also raise a ticket with AMD at http://support.amd.com/en-us/kb-articles/Pages/ticketprocess.aspx
Since EA has not acknowledged the error on their top issues post on Battlelog, you could also request so on Battlelog and to your friendly neighborhood EA Advisor.
tried the new realtek driver, didnt help.
joined a server that was on zavod and even during the loading screen my memory got full and was unplayable when i was done loading.
