A RAM Question
-
Looking to purchase 4GB of RAM for a server I want to build at home. Looking at what's available from the wholesaler (finish up at work Friday so better buy now while I have access) I have two choices. They have different timings and therefore price but don't know if I will benefit from the higher priced lower latency RAM. So here I am asking the software experts for hardware advice. First choice is Corsair DDR2-6400 C5[^] which I have the cash ready to go in my pocket. Second choice is Corsair DDR2-6400 C4 DHX[^] which is AUD$63.00 more and I don't have the dollars available that the Missus won't miss. So will the C4 stuff give me any benefit over the C5 when I'm going to be putting it in a Gigabyte MB (can't remember it now off the top of my head now I'm at work) with an AMD X2 6000 CPU?

Why not get ram with ECC? It's not that much more, and will compensate for the random gamma rays.

The only real difference that matters is the ability to absorb heat. Unless you have a real problem cooling your box the C5 will do you just fine.

Depends on the applications, but most of the time i'd go with the first choice. There are very few server applications where you're really going to need the extra performance.

You will run 64 bit windows ? If not, it won't see 4 GB anyhwo

Truth be told the AMD X2 6000+ is my desktop and is running XP Professional 32 bit and I only get 3.5GB of RAM available. The server will be running an Abit MB, AMD X2 4800+, 4GB od A-Data RAM and 64bit CentOS Linux, so it will see the whole 4GB. I am giving it 4GB cause I'm going to play around with Virtualization at some point and want the extra RAM available.

I was thinking about cosmic rays.
So the creationist says: Everything must have a designer. God designed everything. I say: Why is God the only exception? Why not make the "designs" (like man) exceptions and make God a creation of man?

On the contrary, it looks like that number (3.5gb) indicates how much RAM is addressible by one process. If you have PAE (probably yes) it will report (my buddy has PAE and >4GB RAM and his reports 3.5GB) you can use all the memory, but only 3.5GB per process. I think. Have a look at what MS has to say about it[^].

The reason you see 3.5gb available on a 32 bit system is because on 32bit 4gb is the maximum addressable memory. Everything has to be included in this 4gb limit to be addressable. This includes video ram and all I/O hardware. So if you have a 512mb graphics card, that 512mb is mapped onto the top end of the 4gb address range, so effectively prevents you from using the top .5gb of your main ram. IIRC XP is limited to 4gb of physical address space even with PAE turned on. PAE just allows individual processes to use beyond the usual 2gb process limit. http://www.microsoft.com/whdc/system/platform/server/PAE/pae_os.mspx[^]

Yeah, but on many boards the next suitable option is 2G, which sucks for superstars like us.
