it's already been a long day, i read that as you had an athlon. my mistake.
this model has 512kb of L2 cache per core for a total of 2mb. i have done some googling and can't find any info about L3 cache at all, which is strange also. it looks to me like a 900 series but without L3 cache. so it's strange your board would recognize the model correctly but also show 6mb of L3 cache.
im search google too iand i know for a fact that it didnt have one but i seen 1 comment somewhere that supposedly it had an l3 cache and looked in my bios as i knew it didnt but it appeared it did, i know people dont like this cpu for its lack of l3 cache but hey hello gooddays lol
