Anyone run PIII on a BX MoBo?

[reset74]

Hi,
Anyone upgrade their old BX chipset board with a PIII? I have a P2B and wonder if anones had success with either the Slotket/FCPGA or SECC upgrade route.

[KILLorBE]

I didn't but it is possible.
Go here (http://www.overclockers.com/tips296/) for more info.

I'm on a BE6 which has a 440bx chipset

[ech0]

I run P3 800 on P2B-F, and OC to 920 at 115FSB. and it's stable.
I am using Asus S370-DL with 1.8V.
But for P2B only limited up to 1Ghz for Now. Because the current bios does not support >1Ghz

[DaveB]

Absolutely, the BX still runs PIIIs the fastest. I've been running a PIII 700 @994 MHz since July of 2000 on my Soyo SY-6BA+IV BX motherboard.

[reset74]

I understand that the primary upgrade path from a BX chipset board (like the P2B I have) to the PIII is to use the PIII Coppermine 'E' (100MHZ FSB) and a Slotket. As was mentioned, this tops out at the PIII 1GHZ/100FSB CPU, Slotket at 1.8v (the FCPGA PIII/1GHZ/100FSBs vCore being 1,75v).
Any comment about the PIII/1GHZ/100FSB SECC2 variants of this CPU? Their vCore is 1.70v so you'd be running more of an overvoltage. PIII voltages here:

slockets are good, for one reason because theyre easier and cheaper to cool (ie slot1 heatsinks costing more as supply goes down) secc-2s are good though and should work on your board...

Any comments as to the best HSF for a slotketed PIII/1GHZ/100FSB?

running a cele 566@850 on my BP6 440BX board and it runs great

upgrading to a P3 1100E in a few days

[muddocktor]

I have had both the slot1 P3 1000E and now I'm running a FCPGA 1000E. I've run both procs on my old board(BH6) and my new board in my sig. The slot 1 is a cC0 stepping proc sold qualified for 3 different Intel server boards only, which is just BS. It will run just fine in just about any BX board that will support Coppermine's voltages. I had oc'ed to 1120 and stable. The new cD0 P3 1000E flip chips will oc quite a bit better though. Both of these cpu's run on a 100 fsb, so if you don't want to oc them, they will run within all the BX specs. I'm presently using an Alpha PEP66 hsf on my 1000E with a 30 cfm Delta fan. I chose the PEP66 because it takes up less room when you are running a slotket because of the way the fan mounts. You can also find pretty good deals on them now because they have been around a while and are not the newest kid on the block any more. Hope this helps you out.

Thanks for the reply,
What manufacturers slotket are you using with your FCPGA PIII/1GHZ/100FSB? I assume you've set your vCore to 1.8v on that rig?
Why two different rigs (slotket/FCPGA vs SECC)?
Which do you think is better?

Since it's Socket 370 and no longer a slot I would recommend the Umm Volcano 6cu+ ( Cheap, good performance, loud with delta copper base)

SK-6( Expensive, Loud, All Copper, #2 best heatsink)

reset74,

I've run P///'s on BX boards for a while, and it's a great combo. As to what would be a good choice for a slotket and HSF;

Soltek SL02A++ is what I've used for a slotket, never had a problem with it, has jumpers onboard for vcore adjustment from 1.3 to 3.3v (before you get to the BIOS, where you can adjust further...like you would need to...lol), jumpers to select "Auto/100/133 FSB" settings, and yet more jumpers to let you select between a PPGA or FC-PGA chip (meaning Coppermine compatable).

There's a few other good ones out there, but that's what I've had the best luck with...;)

HSF: The Alpha PEP66T is designed for a slotket application... mine came w/ a kinda cheezy 60x60x10mm Delta fan (silent, but weak), but that's easily replaced by a YS Tech 27CFM (quiet and better) or a Delta 38CFM (loud but very effective) fan.

I just got a Millennium Glaciator II Aluminum "Lite" HSF... I'll be testing this out on my slotket mounted P/// 700E shortly... I'll be either posting results here, or writing something up for the front page... I wrote an article quite some time ago, doing a comparison between the Alpha PEP66T, and the original Millennium Glaciator HSF's;

http://www.overclockers.com/articles433/

I'll be interested in seeing how the Glaciator "Lite" stacks up against those numbers..... ;)

Cheers! :beer:

**edit...in the article, I mention having to bend the ZIF arm on the CPU socket to clear the Glaciator... this area has been machined away on the Glaciator II, and Glaciator II "Lite", so no bending is required...:) **

Actually later BX motherboards can provide the correct default voltage. My Soyo SY-6BA+IV provides the 1.65V default core value for my FC-PGA PIII 700. Older BX boards come with regulators that can't go below 1.8V, but that isn't a problem. To overclock mine to 994 MHz, I had to set the core voltage to 1.95V on my Iwill Slotket II anyway. I use an Alpha PEP66 with a relatively quiet Sunon 5000 rpm fan. I also used two Asus S370-DL slotkets on my old PIII 700 @ 933 MHz duallie. They work great also but have weird retension mechanisms.

[muddocktor]

I am using an Abit slotket 3 on my chip but I don't think that they are made any more because I haven't seen any for sale in a long time. I know that azzo has the Asus slotkets still, but their prices are kind of high, around $30. I had bought the slot 1 1000E cpu before the cD0 flip chip 1000E cpu was on the market. They are nice procs but don't overclock as well as the newer ones.

Both boards that I have run the flip chip cpu on have been able to autodetect the correct voltage. However, you can use the voltage jumpers on your slotket to your advantage with the Soyo board. It lets you raise your vcore by up to 10%, so if you think that you need more vcore than the stock vcore will allow, you can set the vcore higher with the slotket and my board will let you give up to 10% more of the value that was set on the slotket.

As far as the fans go, I'm using the 30 cfm Delta because it's as quiet as the 27 cfm YS Tech and flows a little more cfm. It doesn't have the annoying whine of the 38 cfm Delta black label fans either.

[reset74]

Could someone explain to me what kind of voltages I'd be dealing with should I go with a Slotketed PIII on a BX Mobo?
As was pointed out, the earlier rev Mobos (like my P2B rev 1.02) have a vreg that can only go down to 1.8v. vCore on a FCPGA PIII/1GHZ/100FSB for example is 1.75v. I'd assumed I'd set the Slotket voltage at 1.75v and that would be it.
What are you talking about with Slotkets providing 1.3v? I think I'm missing something here.

[Yodums]

Try 1.8 v with a cool fan and overclocking shouldn't be a problem since you would need to up the voltage to 1.8 anyways.

[reset74]

So theres only one voltage to set on the slotket, the vCore, have I got that right?
I set it to 1.8v as thats the lowest my MoBos vreg will go, and run .5v overvoltage and thats it.
And a good HSF of course.

If I understand your question right..

You can set the slotket from anywhere to 1.3v to 3v+..

As long as your mobo supports it as for you, you would set it at 1.8 and then up the voltage from the bios.

[tech211]

1 of my systems has SOYO 6BA+100 RUNNING A P3 450@600 (133X4.5) ROCK solid @ 43C and thats a BX chipset. not too shabby for a 100 mhz board EH! I also have run celery900@1138 in a slocket on that board.

[reset74]

The more I look at the specs of my P2B rev 1.02 the less likely the upgrade to a PIII looks. First the vreg only goes down to 1.8v, which is ok with the FCPGA/PIII/1GHZ/100FSB which uses 1.75v. But the killer is that the multiplier only gos to 8x, and this is via jumpers, so no 10x for the PIII/1GHZ. If I use a PIII/800/100FSB(1.65 vCore) then I'd be running an overvoltage of .15v.
Its true I could do some overclocking of the P450 I have on the P2B right now, but I was looking for an upgrade that wouldn't mess with the PCI/AGP freqs. Thems the breaks.

[reset74]

Ok, reread an article on upgrading the P2B with a PIII here:

http://www.overclockers.com/tips296/index.asp

Which mentions that though earlier board revs of the P2B have a Multiplier that only goes up to 8X, it no longer matters as PIIIs all have locked multipliers. Recently talked to someone with a P2B using a PIII 850 on a P2B successfully so at this point I'm convinced an FCPGA/PIII/1GHZ/100FSB on a slotket will work. Probably going with an ASUS S370-133 Slotket set at 1.8v (as thats the lowest the P2B can supply anyways. Depending on stepping, FCPGA/PIII/1GHZ/100FSB has a vCore of 1.7 or 1.75v.
Thanks for all the replys, time to close up the tread and give it a try.

[Yodums]

Correct me if I'm wrong but the slotket requires a supporting multiplier to run that chip..
So if you were to run a 1.1 Celeron you would require a 11 Multiplier hmm..

I don't know how he got it maybe it supports all 8 multipliers..

[JaY_III]

Intel has locked the multipliler, and you can not change it.
and if you do, the CPU doesnt care what you set the mutliplier up as, it will use the multiplier that intel said it should use.

So no you dont need an 11X mulitiplier really

My Celeron 600 (cC0) that's I've got stashed away in the closet these days, I had running on a 6BA+III (two versions older than your +100). Mounted in the Soltek slotket I mention above, I got 1053MHz outta that chip... :D

Good board. Better chip. ;)

Multipliers are irrelevant. Don't woory about that....the chip will run whatever multi it's supposed to.... That C600 is a 9x multi... I've had it on a number of boards that only "officially" supported 8x. 1.8v isn't a problem either, even if setting a lower voltage thru the slotket doesn't fly with the BIOS (ie; the BIOS runs 1.8v and you've set the slotket to 1.75v). If you're gonna O/C that chip, you'll likely go higher than 1.8v anyways.

You're good to go. :p
