1GB Memory RH7.3

Hello!!!

I've just bought my second computer, and the plan was that it should run as a counter-strike server (LAN only)
The computer has 1GB memory

)

But then a friend told me that Red Hat linux v7.3 doesn't support that much memory. Is that true - if yes, what do i need, to make it work?

Best Regards

As far as i know Linux supports 32 GB of memory, and that can be further extended by compiling special options (Support for more memory) into the kernel.
Correct me if i'm wrong here, but you should not have any problems with 1 gb of memory.
Hope that helps

OK, that was allso what I thougt - but I had to be sure.
How many servers do you think it can handle?
It's a T-bird 1.4Ghz, Abit KT7A-Raid, 1GB MEM, Networkcard. 10/100Mbit

How many it will support depends but i should imagine that the network connection sets the limit. You will have to try it out. It should support a bunch.

Striaght out of the kernel make menuconfig for 2.4.18 (RH 7.3's kernel):

CONFIG_NOHIGHMEM:

? Linux can use up to 64 Gigabytes of physical memory on x86 systems.
? However, the address space of 32-bit x86 processors is only 4
? Gigabytes large. That means that, if you have a large amount of
? physical memory, not all of it can be "permanently mapped" by the
? kernel. The physical memory that's not permanently mapped is called
? "high memory".

? If you are compiling a kernel which will never run on a machine with
? more than 960 megabytes of total physical RAM, answer "off" here (defau
? choice and suitable for most users). This will result in a "3GB/1GB"
? split: 3GB are mapped so that each process sees a 3GB virtual memory
? space and the remaining part of the 4GB virtual memory space is used
? by the kernel to permanently map as much physical memory as
? possible.

By default this is configured "off" in most distros. I think the machine will be fine, but will only map and use the first 960 Mb. You'll have to compile your kernel with Highmem on in order to get it to work right... I think. Regardless, if the kernel pukes on load, just yank one of the sticks, re-compile the kernel, slap the stick back in and your good to go.

I've got the same board, .2Ghz slower chip, only 768Mb RAM :=(
