Supermicro X5DAE & 800MHz Xeons?

[Guest]

Archived from groups: alt.comp.hardware.overclocking (More info?)

Hello,

I'm running a pair of 2.4GHz (533 FSB) Xeons in a X5DAE board quite
happily. I can get my hands on a pair of used 3.2GHz (800MHz FSB, 1MB
L2) processors for next to nothing - I wonder if it's worth it though.

I should be able to plug the CPUs in, but if the new ones are locked to
a 4x multiplier then running them at 4x533 (533 is the most the X5DAE
can do) will only give me ~2.1GHz, and I might be worse off than I am
right now with the 4.5x533 pair. Granted, I'll have double the L2 cache
but that's not relevant in all usage scenarios.

So the question is: do you know if the X5DAE and 800 FSB Xeons will
play nice and allow me to select 6x533, or even more? (Watercooling is
in place. But the Supermicro board is not an overclockers dream...)

If you can change the FSB, don't do it for just the extra Megs.
I have an Asus PC-DL Deluxe with 2 Xeon 2.66 GHz on it @ 3.2 GHz
My ram is running @ PC3200 Speeds, I cant say weather or not it's stable
though.
2 x PC2100 (No Name) 2x256=512
2 x PC2700 (Kingmax) 2x256=512
Total of 1Gig.
I'm running faster then that of true 3.2 GHz 1 Meg chip(s).

Here's a place to find more info on all the Xeon's.
http://processorfinder.intel.com/scripts/list.asp
There's enough out there to choose from.
+ I wouldn't want to get a Xeon CPU Based on the same tech as the
(Prescott) core.
If I were you, I would just stick with the (Prestonia) core.
That's what my 2.66 GHz CPU's are.


Just saying the 90nm Tech didn't work that well with desktop systems,
why would it work any better with servers.
My CPU Specs From Intel
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL73M&ProcFam=528
&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL
One of the reasons I lost a slight bit of performance, I did the math and
realized I was around
-5 to 1 watt over,, dah, Oops. Needs more on the 12v side.
I got rid of just one HDD, my levels stayed closer to the same when doing a
Sandra
benchmark, rather then going up & down every time I tested.
I would have to guess I have about 8 or 9 extra watts on the 12v rail.
Max Watts on the 12v is only 180 Watts, the one I ordered from some1 on ebay
totals to 288 Watts.

My point?
Make sure you have enough power too, something @ least 600 Watts.
Getting a server PSU is a good idea if you don't already have one.

For CPU, just get 2.66 or 2.8 GHz chips with 533 (Bus)
Notice, on the Intel pages they list it as Bus Speed Not (FSB)

More to say here.

I have most these numbers beat with my Overclock, not the AMD's on all
sides.
But the Xeon 3.4 GHz cpu's I do @ least have beat on the Sandra marks.
2.66 Was running 3.2 I turned it up to 3.24 GHz

In other words, don't waste your money.
Get either 2 2.66 or 2.8 CPU's, or just one @ a time.
I can run with both, I just felt I had to have them both..
