update- i buy another XFX rx 470 8gb is same model,But same problem gpu-z and hw-info tell me when play intensive game example :metro exodus maximum 4gb use not full 8gb,is from OS W7x64 or driver,hadrware?
Ok, so now that you've got the GPU without missing capacitors hopefully
let's address the VRAM usage.
1. The VRAM usage is never constant and will be less than the total amount installed. My card doesn't use 100% of VRAM. I installed the MSI Afterburner with Riva Statistics Tuner (they come together) and made adjustments to show them during recording - on my Windows10 and I can just use Windows+G keys on the keyboard to record the desktop or games. Sometimes I record my testing (computers are just a hobby, but I do some testing for my own curiosity) with Radeon ReLive, which is a part ofd the most recent AMD Adrenaline Drivers (google AMD drivers, you will get there - if you didn't). So, I only play Titanfall2 and on my old machine (7700k/MaximusIX/Asus Strix RX580-8gb) my VRAM usage was jumping from 5Gb to 6.5Gb usage - and this is on an RX580 with 8gb VRAM. So, the first thing to keep in mind is that not all the ram will be used by all games, but there are a few games (some of the Tomb Raiders) that can use a lot
2. To Windows7 - apparently, yes, there was a problem with VRAM usage on Windows7x64. Here is a thread from the same nvidia community about DX9 limitation of vram usage to 4Gb:
Maybe you need to also update your DX library:
3. It's a bit difficult to know what is the real reason in your situation - maybe your GPU just doesn't need more than 4Gb (see point 1) for your specific game and everything is fine.
First of all try to talk to the people who play the same game and ask them how much VRAM their machines consume? Alternatively, if you have a willing friend, you can just install the game and the GPU on a Windows 10 machine to check if there is a big difference - some difference will happen! That's normal.
It very well might be that
is correct. Let's not forget that different pieces of software contradict each other quite often and as I said some games do not take advantage of all VRAM. I also incline to believe that in your case everything is ok, but you can try what I suggested and go beyond that. It is up to you.
4. Going beyond the first phase - if you asked around or tested on Windows10 and people don't have the 4Gb problem - ok, then we can suspect Windows 7 with much higher certainty. If you want to eliminate Windows7 out of the equation, you do know that you can still upgrade for free from Windows7 to Windows10? If Windows 10 can solve your problems, which it might (but don't treat it as a "promise" ok?! I know people tend to say "but you said it will", so, it's not a promise
) then you might want to upgrade to Windows 10. Just save your everything (documents, bookmarks, etc), then download on a USB the INF drivers for the CPU, then the drivers for your mobo (chipset/MEI, SATA, Wifi, LAN, AudoHD and USB), then the AMD Drivers for windows 10x64 for your RX GPU, and then you have two options:
a. upgrade your machine directly with the media creation tool ("upgrade this PC" option) - this is a method of slapping the newer Windows10 over the older Windows7, and I am not a big fan of that. It works, but the PC is faster with a completely clean install;
b. or the other option it offers - create a Windows installation USB (it will delete everything on that USB and create Windows installation bootable media - but you will need to set the USB as boot override from BIOS). You can then do a perfectly clean install - your Motherboard already has a Windows activation on it (yes the Windows 7 activation will be still recognized even if you delete the old Windows totally and do a clean install of Windows 10 on a system where windows was already running) and it "remembers" Windows' serial number linked to this hardware, even if you do a clean install. Again, it just doesn't matter that it was Windows7 - the only thing you have to do is to click "I don't have the product key now" (or something like that) during Windows installation.
Here is the Windows Media Creation Tool link directly from Microsoft:
(c. reserve option - if the activation somehow doesn't work, it did every time I used that method, without exceptions - you can still buy a key for $13-$17 form here:
or Pro here:
I must say that I helped a guy who also believed that such a Windows "upgrade" via a clean installation was not possible, but when he was successful, he was shocked
And don't think that it doesn't work in Eastern Europe or EU, 'cause... it does
Oh, after you have created the USB with Windows installation, create on it a folder for drivers (give it a name you want), then you'll have them ready for install as soon as the Windows boots. After Windows 10 install, do the installation of all the drivers in the order I described them to you in pt. 4, restarting after each driver.
