ASUS A8N-SLI Motherboard – Not what I expected

I tried posting this on NewEgg’s review forum and it censored me. Apparently it doesn’t let you post honest reviews, so I’m posting it here.

I was very disapointed with this product. maybe it’s the state of the technology but I had expectations this board would actually work. BEWARE – As of right now 09/04/2005 there are no ram combinations listed that will get you to 4 gigs of ram. I need 4 gigs and struggling to find a solution. I AM NOT HAPPY!!!

I first ordered it with Rosewill ram figuring that if the system needs DDR-400 that it will take DDR-400 memory. Silly me. I don’t yet know if the memory is bad or just incompatible.

Then I went to Fry’s and bought some high powered Kingston KHX3200/1GR gamer’s memory and it does seem to work, sort of. That is – works with 2 gigs installed. There seems to be issues with 4 gigs that I have yet to resolve. Running Fedora Core 4 Linux 64 bit version.

The CPU – Athlon 4400+ X2 dual core and memory access speeds are lower that my Pentium 2.8 ghz extreme edition. L2 cache data transfer rate is 1/4th that of the P4 and main memory bandwidth is 1/4 of the 6.4 GHZ that AMD advertizes.

When you buy a 64 bit CPU you expect it to be able to at least address 4 gigs of ram. If this were a 32 bit processor I could understan that this would be an issue.

Bottom line is – I spent $1000 on memory alone and I don’t see light at the end of the tunnel.

UPDATE – I did get this working. I got the Kingstom ram to work by recompiling the Kernel. Actually I unstalled the 2.6.13 kernel and I don’t know if it was different options or if they fixed something in the new kernel – but – it’s working and it’s fast. So I am now happy.

Apparently this is more bleading edge than I thought. Probably 6 months from now it will be more mainstream and stable. This 4 gig barrier reminds me of the old 640k PC days with upper memory and the 1 meg barrier. It is similar in that as of now certian things need to live below the 4 gig line so if you have 4 gigs you have to remap ram to open up a hole for PCI stuff, roms, and video ram. That means you have to move memory and when you do – the operating system has to understand that. Fortunately Linux does. If you’re running Windows – lots of luck! It’s going to be a while before Windows deals with the 4 gig barrier.

So – this sucker seems to be seriously fast. Comparing it to benchmarks posted on Webhostingtalk it is running at around the same speed as 2 AMD Opterons. It’s going to be interesting to see how it runs as my new server.

Is your kernel configured to address 4GB? Many stock kernels are not and you may need to compile one yourself.

Yeah, linux rocks like that.
