HD7950 Memory Question

[epuigvros]

Hello everyone, I've just installed my new Sapphire HD7950 and dxdiag reports that the memory of the card is 738MB

GPU-Z reports having 3GB though. I am a bit confused, can somebody explain why dxdiag shows I have 738MB only. Is everything OK?

Here are the captures from GPU-Z and dxdiag:

I have the same card and dxdiag reports it as 2782MB and GPUZ reports it as 3072MB. I'm guessing it's either a glitch or more likely it's accounting for something else.

Are you using 64-bit Windows?

Yes

I have 2 1gb cards and mine shows this, so I guess don't worry

Exactly the same for me with same card.
Im thinking its due to pre-cert drivers, you know not having official MS approval or whatever.

It does say "Approx. total memory".

It does say "Approx. total memory".

738MB is 24% of 3072MB

 

[3DVagabond]

738MB is 24% of 3072MB

So, it doesn't fit your definition of approximately. :shrug:











It's a joke, man!

2x2GB GSKILL DDR3-1333

Played Diablo 3 beta perfectly at constant 60FPS VSync enabled.

This evening I am gonna try BF3 and I will post some results.

Yesterday I benchmarked my system using 3DMark 11, I've scored 6500. Not bad, I've compared to other bench with similar systems and I am approximately in the middle.

However, 3DMark reports my GPU has 1024MB

My specs are:
Core i5 2500 stock
GA-P67A-UD4-B3
Sapphire HD 7950 810/1250
2x2GB GSkill DDR3-1333

I had no time to play BF3 though.

i wouldnt worry about it. dxdiag says my 5870eye6 has 4gb.

I think I found an explanation:

I am at work now, this evening I will check it on my PC.

Thank you all

The adapter properties shows 3072MB of Dedicated Video Memory:

But still no idea why dxdiag reports 732MB.

You should be more worried about your ram, 4gb is too less for a high end system, get 8-16gb

 

[epuigvros]

Yeah, I'm getting those soon:

With a high end setup ideally you should go for 16gb so that you don't need to upgrade for at least 1.5 years or so. And prices couldn't be better.

Chances are he doesn't need anywhere near that amount of RAM. Don't overspend just because it's cheap, it's still wasting money.

 

[epuigvros]

Yeah, I'm getting 8GB, I don't need anymore. But thanks for the advice. :thumbsup:

After upgrading my memory from 4GB to 8GB, now dxdiag shows 2782MB of "Approx. Total Memory"
