1GHz PIII EB & Shim

[Fisheagle]

I am considering purchasing a 1 GHz PIII EB an Alpha P3125S hsf and a Abit Slotket for my Abit BE6-2. Should I also purchase a non-conductive shim to be installed between the CPU core and the heatsink?

All suggestions welcome.

By the way the www.heatsinkfactory.com (http://www.heatsinkfactory.com) really treated me great when I really (unintentionally) jerked them around with an order.

Fisheagle, I haven't read much concerning the Intel chips, but I would assume they are as easy to chip the edges when installing or removing a heatsink as the AMD processors are. Thats what the shims were designed for, to preclude the heatsink from rocking around, or from someone not installing it level and flat on the core. Just a very small chip will kill most of the processors, and from what all I have read at several forums, its a good insurance policy.

One thing to observe if you do install a shim. Be certain it is not too thick. If it is even the slightest amount too thick, it will elevate the heatsink above the core, and temps will go thru the roof. Place the shim on the cpu before it is installed in the socket, and take a straight edge and place across the shim and core. The straight edge must touch the core. Use a small plastic ruler or credit card or something simular as a straight edge. Place the cpu pin down on an antistatic surface, like a bag that a video card comes in.

Thanks Bovon,

Will heed your advise.

Just found this:

It may be of some interest to you.

Thanks again

Fisheagle that Alpha cooler will not work on a slotket. That hsf is designed for a slot 1 processor cartridge. A slotket is designed to adapt a fcpga chip to work on a slot 1 motherboard. If you are planning on using a fcpga ( flip chip ) a good choice would be an Alpha PAL6035 for socket 370 chipsets. I use one of these with my BE62 and an Abit SlotketIII and a 850e PIII fcpga. This setup works great and I havent had any problems to speak of. If you are using a slot 1 processor the hsf you suggested will work just fine but you will not need the slotket. Also you may loose use of one of your dimm slots, thats a big hsf.
Good luck!
Almost forgot, the Alpha cooler has 4 small pads on the corners of the heatsink to help keep it even. They seem to work just fine.

In your BOIS, what AGP settings does your board offer?


I've been through all of this when upgrading my current processor so I know you must be a little confused as to which way to go.

You may only have one viable choice.

Thanks "fshanda",

I have received alot of conflicting info on Slotket hsf thing. Your info seems to be the most definitive.

Thanks again

Hi "ck42866"

I just checked the bios options on my recently flashed Abit BE6-II they are:

AGP 1/1 & 2/3
PCI 1/4, 1/2 & 1/3

[Bsdboy]

You have good PCI dividers for 133(and more)
but your AGP may be a problem depending on
if you video card can handle 88.7mhz(this is
what your AGP speed is at 133mhz fsb with a 2/3 divider).

Hello again "Bsdboy"

I have an old Matrox G200 which requires 66 MGz. I guess I have to do buy a new VC... ouch.

Is there any way of getting the Matrox to work? Is it just a heat problem... can I dip it in nitrogen or something?

[Bsdboy]

Well I don't know about your card but it might handle the higher mhz BTW all agp cards
are supposed to run at 66mhz but many will
run at higher speeds.Ask I'm sure someone here can tell you the chances of your card
running at higher speed.

Again Good Luck

[ck42866]

Bsdboy, has a very good point. That is precisely what I was gearing the question torward.

So an even easier decision is to go {sigh} 1GHZ "E"

Keep the video card, keep the RAM and keep your sanity.

ck42866:I have made my opinions on that known to Fisheagle on his other thread but
it is his choice to make.

Fisheagle: on the topic of shims I think at
best they are totaly unnecessary.

Found this great source. You probably already know most of it, but it sure helped me: http://www.bxboards.com/tips.shtml

[Bsdboy]

Fish that is a good place to start I went
there when I started overclocking.

I would agree with you "Bsdboy" as far as thermal benefits are concerned. I was considering a shim for the mechanical protection it provides during hsf installation, especially for those of us who are all thumbs.

[Bsdboy]

Fish:PIII's arent too fragile but if a shim
makes you more comfortable why not?

Good Luck
