Xeons.....

[ScaryDecoy]

I am curious how a pair of 2.4ghz or higher Xeons would overclock. I am about ready to buy a new rig and I think I want a Dualie, but no one ever seems to o/c them. So I am hoping I can find someone with exp. I am leaning toward the Iwill DP533 and some good PC3200 Corsair memory.

Sounds nice, and expensive!
I would imagine the amount of people to have OC'd a Xeon is low, especially dual Xeons. I can only recommend that you get 2 of the biggest and best PSU's you can find as I am sure most PSU's struggle with 1 3ghz P4, never mind two!
Try a post in the duallie section perhaps....

I am looking at it like this, I can get 2 xeon 2.6 for the price of one 3.06 p4. the motherboard is what hurts, it will be 300 more then a Granitebay board. I only want to do a moderate o/c, nothing extreme just a little extra umph. If i could get the 2.6's to like 2.8 that would be great.

A Xeon 2.6 should have no trouble getting to 2.8, but there are very few boards that let you OC a Xeon. Supposedly there is an Iwill board that supports overclocking; you might poke around their website for a while.

I'm not sure how much good two psus will do, but you would definitely need one good one. Depending on the board you buy, you will probably need a server power supply.

even if you buy a motherboard that doent support overclocking doesnt mean you cant overclock.
If you build a Turbo PLL for the board, you now have the option to change your FSB...
And i do belive (correct me if i am wrong) XEONS are unlocked downwards, so you can lower the multiplier.

[ScaryDecoy]

I remember hereing that about the multipliers one time awhile ago, if it is true that would be interesting. also the iwill DP533 is overclockable. It's close to $550 bucks though. It is the same chipset as the granite bay but for xeons basically.

Also keep in mind that there are now two different types of Xeons. The regular Xeon, and the Xeon MP. The regular Xeon will only go dual, and is almost exactly the same as a regular P4 but with hyperthreading and with sopport for having dual CPU's (only two). The MP's have support for multiple CPU's (more than two). I've only had experiences with the regular Xeon, but I think the limiting factor in overclocking them are the motherboards that support them.

[JaY_III]

Xeon MP's also cost an arm and a leg...
oh and they have L3 cache, 1 or 2Mb

[ScaryDecoy]

I am looking at the 2.66ghz Xeon. It's the one with the Prestonia core, 533fsb and 512k cache.

or should I go with the 2.6ghz with a 400fsb. All I know about overclocking these things is they should be like a p4, and the only thing I know about o/c a p4 is what I read here. My last machines were a couple of Celeron 1.2's o/c to 1.6.

[JaY_III]

the 2.4's might be a better choice as it is also a C1 and will be alot cheaper....
should overclock about the same. with a good chance of not having to lower the multiplier. Something you may have to do with the 2.66

but do make sure you get a socket 604 Motherboard, and not 603, as the 603 board wont support 133FSB....

you are going to have to let us know how this goes...
as XEONS are not your everyday overclock :D

[ScaryDecoy]

This is the motherboard I am looking at

I will start to build this thing right after X-mas, Had to promise the G/f I would wait.

[JaY_III]

i would really stick with buying a 100FSB CPU if you plan to get that board as it doesnt apear to have any FSB adjustments.
either 100 or 133...
but it looks like you can set the multiplier so...
buy a high multiplier CPU, drop it, and set the FSB to 133

Get the 550w PC Power&Cooling power supply. Rock stable.

Correct me If I am wrong, But Does the Xeon require a special PSU ?!?

Most, but not all, Xeon server boards require a psu with an 8 pin auxilliary power connector (instead of the 4 pin connector that desktop boards use). There are probably adapters available though.
