[SOLVED] "Bank Interleave requested but not enabled" PLEASE HELP

[mateo299]

I fixed memory usage by reinstalling windows and making it from 32bit to 64bit.
When i boot my pc I always get "Bank interleave requested but not enabled" message which effects to my memory usage 6gb (3.22 used). In my bios, bank interleaving can be just set to auto and disabled, it was always in auto but nothing has changed. I tried to update bios for my pc "Sapphire PC-AM2RX790" but it is old motherboard so i cant find bios update. This problem has appeared since i bought 2x2gb of ram which i bought because my games lagged so much. PLEASE HELP.
my pc specs:
Windows edition: Windows 10 pro N
Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 5200+, 2700 Mhz, 2 Core(s), 2 Logical Proscessor(s)
Memory: 6gb (3.22 used)
Bios version: AMI Inc. 080015 4/17/2009
System type: 32-bit Operating System, x64-based processor

6 GB is not going to work. Motherboard is limited to 4 GB.

Another issue is likely to be mismatched or unsupported RAM.

The guiding document is the motherboard's User Manual.

https://www.manualslib.com/products/Sapphire-Audio-Pc-Am2rx780-3891812.html

Verify that I have indeed identified the correct User Manual.

Supported RAM and memory configurations are presented on physically numbered Page10 of the manual.

You must also pay attention to the Notes and Warnings.

Compare your current installation (RAM and slot usage) to the User Manual specifications.

Go to two or three RAM manufacturer's websites. PNY, Kingston, Samsung, etc..

Use their "comparators" to identify RAM modules supported by your motherboard/system.

Hopefully you will find a consensus regarding any given RAM module(s) or kit.

Max is 16GB DDR2

Anyway - for bank interleaving on dual channel board you need a pair of modules or 2 pairs of modules. 6GB - obviously is not a pair. So bank interleaving will not be available.

Ram limit is 16gb. Is there any other solution instead of buying another ram i am searching for this problem more than 2 months. I have 2x1gb and 2x2gb dual channel ddr2. When i go to pc-am2rx790 bios in google i get same download page with 404 error because sapphire deleted drivers page. I pasted that url in wayback machine and i downloaded it but when i open update with instructions inside it says cant run this program under your pc. Please help somehow.

How are ram modules installed?
Should be same capacity modules installed in same color slots.

Like the colors 2x1gb in yellow, 2x2gb in blue, dual channel like they need to be but nothing.

 

[Ralston18]

Per @SkyNetRising - agreed 16 GB.

As for memory module options:

https://www.kingston.com/us/memory/...969&devicetype=7&mfr=SAP&line=PURE CrossFireX

Again, verify that I have (now) found the correct motherboard.

Also check the kits and configuration options via other manufacturers as well.

You may be able to use 2 kits each kit being (2 x 4GB) for a total of 16 GBs RAM

Installed end result being 4 x 4GB memory modules.

However, I expect that you will truly need a 4 x 4GB kit to meet the motherboard's requirements for a full working 16GB of memory.

I dont need 16gb, 6gb is enough for lag preventation but only 3gb is used. Can there by any other solution instead of changing ram. Please i would appriceate it.

No issue with what you would like or have: e.g., 6 GB vs 16 GB of RAM

However, it is the motherboard that dictates what will work.

Mixing RAM modules or otherwise not adhering to what is supported by the motherboard will either simply not work or force performance downward to unacceptable levels. In your situation only 1/2 of the installed memory is useable.

Compromise: Get the applicable/appropriate 2 x 4GB memory kit and configure for dual channel use according to the motherboard's Installation Manual.

Or roll back to just using the 2 x 2GB kit for 4 GB of installed memory. Remove the single 2 GB module that is a mismatch.

I tried it. I removed 2x1gb but still 4gb (3.22 used) like there is some kind of limit.

like there is some kind of limit.

A 32 Bit operating system only supports up to 4 GB RAM in total, this includes VRAM on the graphics card, which means that if you have a graphics card with 1 GB VRAM for example, only 3 GB system RAM will be available

But what it has to do with bank interleaving. I also hear 3 short beeps when i boot my pc.

I mention it, because some of the things you were trying to achieve with regards to adding RAM, will be in vain if you are actually using a 32 bit Windows as mentioned in your first post

I don’t know about the interleaving, which is why I didn’t comment on it.

But if you are in fact using a 32 bit version of Windows as stated in the original post, that is also going to be a problem, since you are trying to use more than 4 gb RAM.

You will have to upgrade to a 64 bit os, if you want to use more than 4 gb RAM in Windows, and since you are trying to use 6 gb, it will not let you use the 6 gb RAM, even if you figure out the interleaving error.

Even if you manage to get the 2 x 2gb RAM to work, the available system RAM would most likely still be around the 3.22 GB windows can currently use, the difference between 4gb and 3.22 gb, is most likely due to RAM used for the gpu -either system reserved RAM for an iGPU or the VRAM on a dedicated graphics card

32 bit OS is limited to 4 GB total, including all other devices with onboard memory, such as a graphics card.

f you had a dedicated graphics card with 2 GB VRAM, Windows would only be able to acces 2 gb RAM out of the total amount of system RAM.

I think it is worth mentioning, so you don't struggle with an issue which occured only when trying to add more RAM, that even if resolved, doesn't get you any further due to OS limitations

You veven mentioned yourself, that you felt you were being held back by some kind of limit, which would actually be correct

Can i somehow make my os 64 bit because i have x64 based processor.
These are my graphics card specs:
Name: NVIDIA GeForce 310
DAC type: Integrated RAMDAC
Device type: full display device
Approx. Total memory: 2107 MB
Display memory: (VRAM): 460 MB
Shared memory: 1647 MB

Your CPU is 64 bit compatible, so that isn't a problem, as you already mentioned.

But an upgrade from 32 bit to 64 bit, requires a complete re-install of Windows, there's no direct upgrade available

EDIT :

This doesn't affect the interleaving problem as far as I know, but it lets you use more than 4 GB total RAM once you have the other problems figured out

Reinstalling windows will not be a problem, i just hope it will at least increases amount of ram. Thank you ill try it.

 

[MadsModsat]

.. i just hope it will at least increases amount of ram

List of total amount of supported RAM with various operating systems

Depending on your 64 bit Windows 10 version, at least 128 GB is supported, and up to 6TB on some versions.

So if your system recognizes the amount of RAM you have installed, and there are no issues caused by or related to the RAM modules themselves, you should be fine

As you can also see in my link, the 4 GB limitation of a 32 bit operating system is also listed

EDIT :

But the recommendations provided by other people in this thread with regards to your RAM configuration, is something you should definately consider as good advice

Thank you so much this fixed my memory usage problem but bank interleave problem is till there. If it doesnt effect performance i will leave it.

 

[MadsModsat]

... but bank interleave problem is till there. If it doesnt effect performance i will leave it.

I'm not familiar with that error personally, and I don't know how or if it affects performance significantly, but when looking at threads on other forums, I've seen 3 possible causes.
I'll list them in the order that seems to be most likely when looking at other people's experiences.

1) The memory configurantion - which could very well be true in your case.
Everything from RAM modules in the wrong DIMMS or mismatched RAM, RAM which is not properly seated, all seem to be a possible cause for the error.
This is what you were suggested to look into by the other users earlier in this thread, and I agree with that advice - especially since you've already mentioned the problem only occured when adding the new (mismatched) RAM modules.

2) Disconnecting USB hard drives, iPods, MP3 players, phones or similar products (anything with its own memory / storage) connected through USB during POST.

3) On some motherboards it is reported as a bug in BIOS, and a BIOS update removed the problem in these cases. But since you haven't been able to find a BIOS update, that is obviously not really an option in your situation.

EDIT

The only thing I can personally think of right now, to compare performance with your specific setup, would be to boot the computer with the original - working - RAM configuration and perform a RAM benchmark.

Switch to the 6 GB configuration and perform the benchmark again and compare the results
