Shared memory on AMD FX?

[z34type]

I don't know why I'm getting a shared memory on my system.
I know mostly integrated gpu on intel and amd apu will have a shared memory example 4gb ram (3.80 usable)

I have a AMD FX-8350, Asus Crosshair V Formula Z and Nvidia GeForce GTX 770 Reference Card.
Its showing on my system specs 12.00gb ( 11.9 usable )

Also just to ad why is my clock speeds at 4.01ghz. Isn't suppose to be on 4.0ghz on stock clocks on these cpu's?

You would need to turn off the integrated GPU in the BIOS if you don't want the computer to use it. If you leave it on the default setting, the board is probably enabling both. Having 11.9 out of 12 is not enough useage to worry about, so you may just want to leave it.

The full-speed CPU makes me think your C1E and/or Cool 'n' Quiet is not enabled in the BIOS.

If both of those are enabled, tell us what model CPU you have, and look in device manager for any unknown devices.

Or OP is using the "high performance" power profile (or has tweaked the current profile to make the processor go full whack at all times).

See, I was assuming someone wouldn't tell their CPU to run at full speed, and then wonder why it was running at full speed .... time will tell I suppose.

But "high performance" sounds so good!

Btw, I'm not sure the OP is saying that their CPU is running 4.01GHz non-stop, I think they're saying that the CPU is 4.0GHz but theirs is running at 4.01GHz (when it's going full tilt). It's like the 11.9 versus 12.0 bit.

- edit - Ooh, post count matches a CPU I wish I had!

Right i know but still it shouldnt be using any type of shared memory at all even if its a small
Gap in memory. My cpu is amd fx8350. And im sure i saw cool n quiet being disabled not sure if i have CE1 or not.

Edit: As for the gpu options. Only thing i saw as an option was set default
PEG/PCI and i switched it to PCI/PEG no difference still sharing memory.

 

[Ketchup]

My apologies z34type, that board does not have integrated graphics.

Do you have the Load 4 GB Settings set to yes in the bios?

I don't see anything else that would be limiting you to 11.9.

 

[mikeymikec]

I'm pretty sure that any >AM3 board will have C1E support.

What graphics card do you have z34type? How much graphics memory does it have?

 

[VirtualLarry]

Reserved memory isn't strictly always because of an IGP. Memory can be reserved by the BIOS or other add-on cards for other reasons too. Do you have RAID enabled, perchance? Or USB3.0?

 

[z34type]

I enabled Cool n Quiet as well a CE1 and my stock clock is 4.00Ghz

I attached my Asus UEFI screenshots I can' seem to find anything where I can change the memory.

The memory hole remapping may be tied into your RAM "bug." See if disabling it changes anything. The memory hole remapping is just moving mappable PCI addressable space to the upper end, so I don't know if it will make any difference in the reported available RAM.

The ECC mode is definitely not needed (unless you know you have ECC RAM).

You didn't mention what bios you were on, but BIOS 0806 added support for your CPU, so if you don't have that one (or higher), it may be causing your issue.

Also, your pics don't show that you enabled C&Q and C1E, but maybe that was before the change.

I have three sticks of Patriot Sector 5 3x4gb ddr3 1600mhz Memory. There are 2 black slots and 2 red slots. Both red slots are filled running dual channel and one is not could that be the culprit?

Are you talking about what bios version i have or what bios category?

and yes it was a before picture after the screenshot I enabled it.

EDIT: After going into the bios uefi mode and disabling the memory hole remapping changed it to 11.4gb usable

 

[VirtualLarry]

I would enable Memory Remapping in BIOS, and leave it at that. Some BIOS/UEFI implementations reserve memory for its own usage. Memory that is not available for use by an OS.

It's not a big deal. It's like what, 100MB? That's pretty trivial.

 

[Ketchup]

Ia agree. Leaving it in the higher range is not a bad idea.

 

[z34type]

It seems that 100mb is used for the hardware reserved its color coded in grey when I check on perform.exe

Ok here's what I noticed this morning. I have a rooted LG G3 and its acting up so I decided to revert everything back to stock. So I have to back up all my personal files on my pc. So I connected it via usb, transfering all my crap from my phone to my pc. I went on my system properties and now its showing 12.0gb ( 7.60gb usable) wtf?

FYI I'm transferring everything to my secondary hdd

i went back on perform.exe while my phone transfers my files to my pc. Its showing 4199mb is being used on hardware reserved.

What slot are you using for each memory stick?

Also:

The physical address range from 7E700000 to FFFFFFFF is reserved by the PCI bus and devices, which leaves a theoretical maximum of 7E700000 bytes (1.976GB) of physical address space, but even some of that is reserved for device memory, which explains why Windows reports 1.97GB.

Now, this was a 2 GB example, but it shows how device drivers, such as for your phone, can have memory reserved.

Ok after transferring everything to my pc. My pc is still stuck at 7.90gb usable out of 12gb. I tried loading defaults settings in bios and still at 7.90gb usable.
So im starting to think this is a hardware problem now.

 

[Ketchup]

If it didn't recognize the full amount, I can see a possible hardware problem. As the "problem" is simply the reserve, it's not actual hardware (like I said about, probably a driver for hardware).

Have you rebooted the machine since you finished?

 

[z34type]

As for slot locations. From the cpu is on the left and ram slots on the right.

1st slot is filled, second slot is filled, third slot is empty and 4th slot is filled.

I also noticed that on cpuz the the module size for the 1st slot is only at 512mb as oppose to the other slots are full 4096mb

 

[Ketchup]

At this point, it would be important to know what the amount in reserved is compared to the size of the memory module, and compared to the CPU-Z numbers. I wonder if it is just not counting the reserved number. Posting a screen shot of where you are seeing incorrect numbers would be quite helpful at this point, I think.

how do you exactly screen shot on windows 8.1? I remember on windows 7 i can always do a prnt screen but doesn't work for win 8.1 sorry about all this problems man just so frustrating. I guess i am not alone on this. I've seen many crosshair v owners suffering the same issues all over the web.

I think it's the way the AMD chipset allocates memory for certain devices, as VirtualLarry was mentioning. I lost interest in AMD several years ago, so maybe someone more familiar can chime in.

As for images, I have been using SceenShotCaptor for years. Great program!

I chose AMD because of the multi-core processing. More cores better for the future games that will support it. Even though single threading performance is not as good intel,but i also went for pricing. I don't see much of a difference in gaming between the two rivals. Anyways, I've own fx-6300 and even the 4100 never had this shared memory issue. Only when I upgraded my board to a Formula Z. Its just weird how much memory went from 11.9gb to 7.90gb out of nowhere and yes I have rebooted many times and messed around with the bios settings.

 

[Ketchup]

OK. please don't take me the wrong way (easy to do in this venue): Nothing wrong with choosing AMD, it is just not for me and my needs and longer.

Have you recently installed or updated anything (such as phone software or devices of any kind)? Do you have any devices that you can access (like your phone) connected to the PC?

From reading your posts, this number looks to have grown since you started the thread, so start looking at things that have changed since that time.
