Hi

Is that true that the max RAM that a PII can address is 512MB ?
If yes, is it worth having 768Mb on an Asus P2B-S with a PII ?

Thanks

Found the answer...

Pentium II Processor Cacheability
Since the L2 cache is on-board, but not on the same die as the core, the processor can cache up to 512MB of memory.
Pentium II processors that are on the dA1 stepping can now cache up to 4GB of memory.

What the heck are you doing with 768mb of memory? Are you running a really big server? Even for most development purposes, 256mb is more than adequate.

It is a test server running NT server 4 and SQL 7.0 with a BIG db.

We want to test the soft before buying the "real" server, which needs 1Gb RAM, RAID5 whith a minimum of 40Gb, and 4 CPU.

Ahhh,..I see. Well, if you're going to be running a serious SQL server that warrants 4 CPUs, you may need MORE than a gig if you're planning on caching alot of the DB in memory. Then again, it depends on the application I suppose. I've seen some boxes with even more outrageous numbers.

do not put more then 512 mb ram in the testbox because when the cpu is adressing more then that 512 mb it slows down for maybe 20 % so put 512 mb in it and it shines !

OK OK...
I have this utility (from Intel) known as CPUID. It tells me about the stepping, freq, ... but it does not tell me if the CPU is on the dA1 stepping.
Anyone knows a utility who could tell me that ?
So, I would know if the CPU I will use in the PC can cache more than 512Mb !

Don't worry about the test PC Brian48. We will build the test PC just to familiarise ourselves with the soft and the installation.
The real server will be probably a 4 way xeon, with 1Gb RAM and at least five 18Gb HD in RAID5.

I wish that could be my gaming machine at home...

Sounds interesting Stan. I'm curious. Do the users have a true 100 connection all the way to the server? Correct me if I'm wrong, but if they don't, would some of that be a simple waste?

Let us know how you make out. I'd like to see what that does on a Novell network also.
