128GB DDR3 Support On Rampage IV Black Edition & ASUS X79 Deluxe

Darktron

There's always the chance you need a Xeon in one of those boards to make it work...

well the i7 range doesnt support ECC ram, and the IMC was designed with a shortcut, so it cant adress 16GB dimms at all. so yes, you will need a xeon and ECC ram for this.

ASUS has been working closly with Intel and IM to make this happen. I would assume that means Intel officially supports ASUS in this.

Actually I'M Intelligent Memory had already stated in their press statement that the memory will work with Asus's x79 boards, and Intel has no plan to analyze the possibility to support them unless there is a huge demand for the memory.....

They went against Intel and created the overclocking options for the B and H series motherboards just recently so wouldn't suprise me if they did this without Intel.

i think intel will not do anything at this point but maybe one day

Hi! I work for a distri of Intelligent Memory and yes, Asus changed the "Memory Reference Code" which is the routine that initializes the memory. It is part of the BIOS, that's why Asus released their own BIOS.

The memory controller hardware (inside of the CPU) just sends an address of row and column to the memory and expects the module to transfer the data back. This row/column addressing is done through total 16 multiplexed address lines and 3 bank lines.

 

16GB modules are using DDR3 8Gbit chips, 8GB modules are made of 4Gbit DDR3 chips.

Both, the 8Gbit and the 4Gbit DRAM chips use the same total number of physical address lines -> 16 lines and 3 bank lines.

Thus I can say that from a hardware point-of-view, every CPU which can work with 8GB modules (made of 4Gbit chips) should also work with 16GB modules (made of 8Gbit chips).

 

Now the only problem left is the software, the Memory Reference Code (short MRC).

 

Intel supplies this MRC code to the motherboard makers and BIOS programmers as a compiled piece of software. And this Intel MRC code is written to setup the memory controller correctly when it sees 1Gbit, 2Gbit or 4Gbit DDR3 chips on a module. Unfortunately this code does not know what to do when it finds 8Gbit chips, so the system just hangs. ASUS added the code for 8Gbit DRAM chips and it works!

 

On the Intelligent Memory modules and the "slow" 1333 speed:

In a few weeks there should be at least 1600 speed, but let's be realistic: How much faster does a system get when using 1600 or 1866 compared to 1333 ?  And I do not talk about the pure memory speed, which might get a bit faster, but the total system speed.

 

When you run any kind of software, a majority of time is taken by the CPU, the logic devices, HDD/SSD access, waiting for mouse/keyboard/network data, etc. Only a small portion of the overall speed is related to the speed of the memory.

Even if a memory test would show you 10 or 15% faster "pure memory speed", the complete system will just get maybe 1-2% faster or you do not notice it at all.

 

But not having enough memory will cause a system to run slow, because it might have to use virtual memory, it swaps the memory to the HDD/SSD, which is taking away all your performance. The system gets awfully slow.

 

The bad news is: Those Intelligent Memory 16GB modules are not really cheap. You can in no way say "they should be twice the price of 8GB modules". We talk about around $330 per module here! So 128GB will get you to $2640 ! You must be really desperate for memory to pay that ;-)

cpus dont have ram limitations lol

The OS does however

For win 7

Starter: 8GB

Home Basic: 8GB

Home Premium: 16GB

Professional: 192GB

Enterprise: 192GB

Ultimate: 192GB

Why did Windows put a RAM limit in it's OS. Linux has a theoretical memory limit of 1TB but that is only because of hardware it's actual limit is 2^64 thats 16 777 216 TB but in reality it's just 256TB

product segmentation. this way they can sell windows server, that has support for waaay more ram ;)

U sir are correct. Basically a way to make more monies.

Xeons would take some juice from this advantage though

If you're using xeons you should use a proper server motherboard, not a gaming motherboard.

Half the features on a gaming motherboard will be useless for a server, plus server mobos support way more than just 192GB of ram.

Yeah... perfect for people who just want to throw money :P

People build server workstations for certain types of jobs and work where you actually need over 64GB of ram and xeon processors.

that's completely not true at all.

Why do you think 32-bit CPU's are limited to 4 billion locations (4GB). Its because they are 32-bit meaning there address bus has 32 lines. you can determine the maximum addressable memory locations as the 2^(lanes of address bus)

 

So:

2^32 = 4,294,967,296 addressable memory locations.

 

Thats how you get your physical RAM limitations. Its the same with 64-bit CPU's.

well...  Yay!  This is awesome!  But I can think of much of a benifit right now to all this RAM, good that we can actually use this much though!  I dont see a benifit right now except...

I didn't mean that, I meant Rampage + Xeon

Ah yes :)

You have to use a CPU that supports ECC memory. So if you installed a Xeon in the board you could utilize it.

They write that, because that's what the controllers are supposed to handle on consumer grade motherboards, but actually the x86-64 architecture can address up to 256 TB of RAM.

There are ways to "hack" into that and actually double the amount of memory the controller is actively handling, doesn't work as well as supposed, but it's possible. What's not possible is addressing more than 256 TB

Too bad that's not your PC. Just because you find an image on google doesn't mean its real. Also even if it is real I doubt a regular PC user will be experienced enough to crack a CPU's memory controller.

On google? I took it from here:

 

 

Seems like none of you realized that Asus showed 128GB working. Asus isn't going to release this bios if only a few cpu's can do it
