My ASUS R9 390 CU II 8GB ram is only using 4GB ram on windows 7 64 bit?

[skippy258]

Hi all, I have been playing all my games with no problems till I started to play FEAR 3 in full specs and while trying to tweak the system a little, I found that my ASUS R9 390 CU II 8GB ram is only using 4GB ram on windows 7 64 bit?



Can anyone tell me why this is happening and how I can make my card run at full 8gb of ram or am I reading this wrong?

what does GPU-Z say?

 

[darkangel0504]

you should play GTA 5 , Shadow of Modor with 4K Virtual Resolution .... with MSI Afterburner OSD

what does GPU-Z say?

This only shows the total amount available on gpuz... as I thought dedicated video memory would be the amount used buy the card, or am I wrong there?

 

[Mussels]

GPU-Z showing the right amount at least proves the card is truly 8GB, and hardware wise its all there.

next up would be what CCC says in the hardware section - if its correct, you can ignore that windows reading.

Thanks for the head up on the MSI Afterburner OSD I have downloaded it and all seems to look nice and has some voltage overclockers nice but the only thing is I can not see how to run the stats while in a game like you have in you 2nd image.
I have downloaded MSI Afterburner 4.1.1 Final

Thanks I looked in CCC it seems to say 8gb so I guess its microsoft but would that bottleneck the hadware from the software not seeing more then 4gb?

go MSI afterburner Properties
Choose what you want to show

Thanks for your reply but I do not have that on mine



Maybe I have to get the RivaTuner 4.1.1 version like you have to see that...

 

[darkangel0504]

I got RivaTuner 6.3.0

 

[Mussels]

you have to select the stat you want to show. select the ram usage then tick the OSD box.

 

[skippy258]

ok will look that Version up @darkangel0504. @Mussels turned out I had to restart my pc... doh!

 

[Mussels]

we didnt need to see all 32 CPU cores, but yeah its using 5.5GB or so of ram so its fine.

I turned them 32 cores on as I was curious to see how much cpu power is needed also what cores the game hammers the most

RAM = System memory
MEM = GPU memory

We won't know unless he uses something that can push usage past 4GB. The question is if the OP can use all 8GB of VRAM not system memory.

it shows two readings, isnt one CPU one GPU? hard to tell when he has ALL of them turned on.

 

[Aquinus]

RAM shows two because the OP has two CPUs with two memory controllers. What we're probably seeing is 11-12GB of memory used total between both CPUs and less than 1GB on the GPU.

 

[Mussels]

i guess OP needs to give us another screeny with VRAM turned on, and the excess stuff turned off.

 

[Aquinus]

It is there, it's next to the memory clock speed. It says he's he using 506 or 606MB in the screenshot, it's hard to tell.

I just edited this out of the other image

 

[Mussels]

ah yep 506MB. clearly you need to run a more demanding game.

12.9 FPS, CPU1 pegged out, GPU running at 7% usage. I think figuring out if you actually have that 8GB of VRAM is the least of your issues. You need something better than a server motherboard to run that GPU. 2.1Ghz of bulldozer cores is simply asking for punishment and poor performance. You need something clocked higher. Honestly, with CPU usage in general so low, you need something like dual 8c variants that are clock a lot higher. Simply put, you have a lot of parallel compute power and games can't use it.

I don't know what to tell you @skippy258 ... I hope you didn't think more cores meant more performance across the board because you have probably the least conducive setup for gaming. The cheapest of cheap APUs probably would perform better...

Yeah its my cpu letting me down. Also had to clone my boot drive again as i found the one i was using was starting to do read fails and would not pass 10% on a scan so cloned that sucker quick

Yeah I know what your saying as games only run on 1 or 2 cores so even if it was a 8 core cpu it would only use 1 core mainly dew to the way the game was built and also DirectX versions up to DX12 and now we have Mantle in windows 10 comming, as i did buy this motherboard to be a steam machine but when i built the steam machine i found I could not play my windows games because its linux based and all my games are windows based so because of this I just built it back into windows 7 pro 64bit. I will change to windows 10 in a few months.
==============================================================
Mantle Enables Better Performance at Lower Power Consumption
What’s perhaps most impressive is that not only did Mantle deliver higher and more consistent framerates. But the low level API also achieved that with better power efficiency. By improving the performance scaling across all CPU cores and reducing the CPU overhead overall. The API allows the game engine to deliver better performance with lower resource utilization and thus lower power consumption.

Enhanced power efficiency may not sound very exciting to enthusiasts. But because the CPU doesn’t have to deal with as harsh a workload is it normally does with DX11. You can leverage the lower power and reduced heat to push your CPU clocks even higher. Delivering even better overall performance.

most of us here are aware of the impending awesome of DX12, but also that it'll take 2-3 years before its CPU power is any use to gamers. not much point building a system for one or two games, at the expense of hundreds of others.

At the end of the day, maybe in about 6months... this system might just become a NAS or a webserver maybe gameserver for the house

Or I could flash it with this new bios that allows overclocking of my CPU Link below:. What do you think? Is the little bit extra speed worth the mucking around?

I have made the USB drive with the new firmware... just tossing up if I should do it or not.

Stable overclock specs is 2.30 i believe at 2880mhz instead of 2.10 @2600mhz

I have a SuperMicro H8DGi-F if you where curious

Also I'm using DVI to my screen and it only dose 60 hz in its highest setting. Will this slow my FPS down? I have a large flatscreen here, that when I hook it up I can use 1080p or 3000x 1900. something like that in screen size should I use the big screen instead of this monitor for games?
