Can I use a CuMine CPU with an Asus P2B MB?

[superfly]

Well the fastest 100mhz fsb fc-pga p3's run at 900 mhz and i believe that the adapter has no problem with that since my bro's system is running at 960(o/c'd).

There are some 1ghz 100 mhz fsb p3's available but they're slot 1 versions,not fc-pga's

You can check it here...

Wow...didn't expect so many replies. Just one more question: is the Abit SlotKet going to work? I'm only able to get this as the Asus is out of stock everywhere.

BTW...thanks to all...u guys are great

Is your bro's system a P2B? Which variant and version? What CPU, FSB? I'm running a v1.03 P2B-S @ 100 MHz. I've got some Mushkin "PC150" but I haven't tried o/c'ing yet: Been meaning to do that this week. Maggi, is 112 MHz the max FSB on my 1.03? That would give me 896 on a 800. Not sure what my FSB options would be on the 900: I've got that info around here somewhere but if somebody knows I'd appreciate an answer.

Lawlaw ... the Abit is the SlotKet that Maggi uses and recommends.

xortam: Ya...but superfly mentioned he got it to work with the Asus converter, so just want to make sure.

superfly: My p2b is rev. 1.02, what about yours? xortam posted the link to Asus web and it says rev. 1.12 is needed for this to work.

Specifically, its the Abit SlotKET!!! that Maggi uses and recommends. The ASUS slockets are hard to get hold of. Never mind what ASUS says (they say not to run over 100 MHz either) ... you're getting advice from the men in the trenches; trial by fire!

[xortam]

... and Maggi run's a v1.02.

[Lawlaw]

ok...that mean i'll contribute $350 to Canada's economy tomorrow...

The asus one that my bro's using has no trouble running at 120mhz fsb(it's been running like that for 3 months now.... ).

The 1.03 version that he's using has fsb adjustments up to 150 mhz and as soon as it hits 133mhz,it sets the the pci bus at it's default value(33 mhz).

The major problem is that there's only a 1/1 or 2/3 setting for the agp bus devider,so in practical terms,setting your fsb much above 120(agp at 90 mhz)probably isn't realistic because of agp bus speed concerns,even if you have sdram rated at 150 mhz.

I picked the asus one because i had no trouble finding them in my area and at the same time,avoid compatibility issues by using a different brand of adapter.

But you probably won't have any problems with the abit one either.

I personally would like to try an ASUS slocket first on my MB, if I can find one when I'm ready. Here's a site that comments on user's experiences with ASUS MBs and Cu chips as well as specific slocket recommendations (based on MB rev). They state that my P2B-S R1.03 can run at max an 800 o/c'ed at 896 w/ 1.80v. They tested my MB with IWill Slocket II Rev 1.1, Asus S370-133 Rev 1.01, and Soltek Slotek SL-02A++. This information was compiled early last year. I think I'll try the 900 w/ an ASUS S370-DL first, depending on pricing and availability. I also see my local shop is selling the retail 850 for $218 but I may want to play with the coolers this time.

Superfly: I've got a Coppermine running at 133MHz, so that's not much of a problem with a 2/3 AGP multiplyer.

I plan to use the Celeron-2 with the Asus slotket with voltage regulators on a Soltek SL-61C... it doesn't have the microcodes for the celeron-2, but I think they'll supply me a BIOS with the correct microcodes if I ask them (adding microcodes isn't really that difficult at all).

Now first I'll have to find a place where they sell those Asus slotkets

having read this thread, I can only surmise that superfly has a late revision 1.10 or 1.12 board or else his pc would not boot if he left the jumpers on the slocket to default. the voltage regulator on the p2b varies on different boards so some are only able to provide a minimum voltage of 1.8V. look at the writing on the voltage regulator & check below to see if it can supply the low default voltage of the coppermine otherwise set the voltage on the slocket to 1.8V in order to boot.
Vcore range
HIP6004ACB 1.80V to 3.50V
HIP6004BCB 1.30V to 3.50V
HIP6019CB 1.80V to 3.50V
HIP6019BCB 1.30V to 3.50V

Make sure that the asus adapter also supports celeron-2 cpu's though,since they only have jumpers for either p3 coppermines,original celeron's and cyrix joshua cpu's.

I'm pretty sure that it'a a 1.03 version since i contacted asus's tech support and gave him the exact version of the board and it's serial number too(it's on the last isa slot)and he said that my particular version does not supply voltages lower than 2.0v,so i would not be able to use slot 1 coppermine cpu's.

And yes the system booted fine with the jumpers set in their default position on the adapter since all it does is identify the cpu and provides the correct voltage automaticaly,regardless of the vrm installed on the motherboard itself.

some more questions Superfly:

why didn't the Asus person mention their Slotket with voltage regulators when he told you your motherboard could supply a voltage below 2.0v?

and secondly, why would you need a jumper for the CPU type installed? The CPU itself identifies it's voltage through some of the connector pins, so that cannot be the reason.
