Anyone else suffering from slower than normal response time with the helpdesk?

I sent in a ticket about a link to order 5GB of Memory for my system a few hours ago and haven't received a response. Usually they send a response within a few minutes, half an hour tops.

I'm pretty sure that unless you have a 64-bit processor you can't exceed 4 gigs. I could be wrong, though.

If you did not receive the auto reply with a ticket number, then support did not receive your ticket. Try manually submitting the ticket through the helpdesk: http://desk.surpasshosting.com and if you did receive the auto-reply, then just be patient, they should get to you soon.

When I e-mailed them about the maximum I could add, they reported 8 GB if I was running on the Xeon which I am using. I'm currently at 3, trying to get it to the max.

You're right

32bit = 4gig max
64bit = insane amount

Plus you have to ran a 64bit Linux or BSD distro. (Net,Open,Free) BSD is already 64bit. Linux there are a few like Gentoo, Slamd64 (Slackware), Debian, Knoppix 64...

It all depends on the motherboard.
For example the Abit AW8-MAX, I955X, Socket-775 runs Celeron and P4 (32-bit)
And it has a max of 8GB RAM.

I don't have to deal with this stuff very often, but I'll take a shot at it.

32-bit Linux can use more than 4GB RAM, with limitations. It uses PAE (Physical Address Extensions) to see up to 64GB RAM.

The limits are that there is a performance hit, and an individual process can still only use up to 3GB of RAM (by default, 4GB - 1GB reserved for the kernel, though with tuning, the amount of memory available to a process can be increased to about 3.75GB, leaving 256K for the kernel, at least with 2.4 kernels).

The amount of memory that can be used will be more of a hardware limit rather than a software limit.

However, even though the OS can handle more than 4GB or RAM, to get the most out of it, a 64-bit platform (Xeon EMT-64, or the "kickin' Intel in the butt" AMD Opteron) should be the first choice.


I had to learn about this the hard way. I had customers trying to load datasets that were crowding the 4GB limit. When 3.75GB wasn't enough, I moved them to dual-cpu Opteron machines running 64-bit RH. Problem solved.
