16GB of RAM? Sound good for quad CPU?

[freecableguy]

8GB or 16GB? This is a quad Itanium 2 system that I am biulding. Will have 1MB L2 cache total, 16MB L3 total, 64MB L4 total (system design)....so 16GB total RAM sound OK?

is this thing going to be a dedicated cruncher or what are its duties going to be.

[freecableguy]

I am thinking I will eventually backbone it somewhere for some serious web hosting for forum boards...like this one. Running SQL Server 2005 (64-bit)....

[Disposibleteen]

i cant imagine it using all 8gb of ram but they say in most cases more is better.

Geez. What's the total cost going to come out to for this system? :eek:

Geez. What's the total cost going to come out to for this system? :eek:

Let's not worry about those details...hehe.

yea, 8gb should be good, but if your crunching with it also, make it around 10 or so for safety. That would be a sick cruncher.

I thought the Itanic had poor IA-32 performance, was this fixed with Itanium 2?

Btw: When you type "Itanic" into wikipedia it redirects to Itanium.

ITANIUM CPU's :eek:

Way da go....

BTW isn't it so that you are now on a list by the US goverment? I heard once they wanted the names and detail of everyone owning Itanium because they resembeld (in power) what the military useses :)

BTW, 8GB for running boards like this IS NOT MUCH (wel its good but people act like it's a superamount)

Remember on XS sometimes over 500 userrs can and WILL be on line thats 500 queries at the same time. (just per user) now take into account browsing, posting, loading of links to thinks like emoticons (which are sometimes also in a database and you have one big Database and query.) Although I think Itaniums are a bit overkill seeing as decent Xeons or Opterons will be capable of handling this load also :)

:toast: damn..... :O this ain't over kill, this is just raw power...ur electricity bill is gunna be higher than cheech and chong :ganja bannana: lol

8GB...seems like it would be enough. But if you've got the money, why not get more :D That's gonna be one heck of a server :toast:

I say 8gb is lots, then up it to 16gb when needed.

[gearhead]

I have heard/read, 32 bit systems cant access or use over ~2 Gb ram, neither the platform nor the OS know what to do with the extra ram. Read it in a computer mag, maybe they were talking about single cpu systems, but the 32 bit os question? One of the reasons I was excited about 64 bit coming out was the ability of the os to utilize the extra ram. Thoughts anyone?

[STEvil]

These CPU's are 64bit.. and the 32bit "limitation" (you can actually get around it) is something like 32-64gb I thought?

[angrysquirrel]

The max memory for a 32bit systems in 2^32 bytes, 4096MB, 4GB.
For a 64bit it's 2^64 bytes, 16384TB, 16PB.

Edit: That's normally per processor.

[dippyskoodlez]

If your gonna buy taht much power, don't bottleneck it with a measly amount of 8gb ram... thats ~2gb per CPU, as long as they aren't sharing a FSB, which i believe they are, but tahts what some people run in their daily systems....

definatly one expensive as heck server, dont skimp on the ram!
