is it normal? i am suspecting that gpu is defected (for other reasons) and this also makes me nerveous, i know if i double it, it makes the correct amount but why do i see it as 3506? is it ok?

Your GPU is fine. The memory clock will increase when the power is needed (ie in games). Just to set your mind at ease, I just started a game and here is the reading on Precision.

thank you so much, i am quite sure the card is defected but not sure if this was the reason, clearly it is not

What other reasons are there?

Vram temp goes beyond 94c degrees while card is on 70, getting black screen whenever i play a game, there are pink artifacts on some games/benchmarks, cant overclock the card at all (not even 1 mhz, it just freezes), underclocking is not helping either etc...

Well that doesn't sound good. Did I see another thread about this?

Probably, yes. I am going to get my other pc today (which is an intel and msi mobo, unlike my current) and test it again, incase i am doing something wrong or my current pc is not good enough...

That's completely normal. EVGA precision and MSI afterburner show the memory clock before it is doubled again due to the nature of GDDR5.

For example, my 660ti reads 3005mhz in afterburner when under load. That is exactly right, since GDDR5 doubles that 3005mhz to the 6ghz operational frequency.

The same is happening with your 770. 3506 x 2 = 7ghz. Totally normal stock speed.
