I have two questions that bothers me, and for which I couldn't find an adequate answers here.

This is my laptop's configuration: HP Probook 455 G1 (Windows 7 Ultimate x64)

  • AMD A8-4500M - 1.96Ghz
  • 4096Mb RAM
  • Chipset AMD A70M Fusion
  • Chiptype (dxdiag) AMD Radeon HD 7640G...
  • Graphics: AMD Radeon HD 8750 2Gb

First, I have a memory problem. In myComputer it displays that only 3.2Gb out of 4Gb is in use. I tried suggestions to change the BIOS but couldn't find where? And in msconfig the maximum memory isn't checked.

Second, because I have 4Gb RAM, and I expect nice performance. Should I buy another RAM module, also 4Gb, so I would have 8Gb in total. When I do that, would it be better for playing games (B4, MW, FC3, etc) and what amount of memory should be usable then? 6.4 or...?

Here's the screenshot: enter image description here

What to do? Should I change anything now, or leave the 3.2GB? If yes, where and how... Should I upgrade RAM?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
How it is indicates I'm not using 64bit OS. I have installed W7 Ultimate x64. And in screenshot you can see that it says 64-bit Operating System. I am obviously missing something, can you guide me where I am wrong and how to set it right. So I shouldn't buy more memory, it won't have effect? –  user3244442 Mar 27 at 21:39
    
No: more memory won't help with BF4 performance... –  Ramhound Mar 27 at 21:41
    
    
very simply, for better performance in games, you want a dedicated graphics card. 8GB will not help that much because the games simply don't use it: many of them stream data and.or precache in dedicated VRAM on the GPU add-in card. –  horatio Mar 27 at 21:43

1 Answer 1

your graphics cards are using some of the memory, the on die 7640G uses atleast ~512MB

So if I upgrade it on 8Gb, it will have something like 7.5 Gb. I am afraid it will stuck on 3.2 and I waste my money –  user3244442 Mar 27 at 21:44

@user3244442 If you're afraid to try anything, why are you here? :) Take it to a computer store and get them to try it, if it works, buy the RAM from them and you're done. –  Ƭᴇcʜιᴇ007 Mar 27 at 21:48
    
That's the procedure that I would follow :) This laptop is weak, but I will try to use the maximum of it –  user3244442 Mar 27 at 21:50
    
it isnt that weak, it has a quad core, and real graphics, meybe reinstall windows, update drivers, upgrade to a SSD (omfg, this is the best path) or more ram (i think a ssd will be a better us of money) –  wiak Mar 28 at 18:55
