P3 1GHz/133 on P2B v1.10: 750MHz possible?

[sheh]

I'm trying to use a Pentium 3 1GHz/133MHz on an ASUS P2B using a noname slocket adapter ("370SP rev 2.0"). The mobo revision is 1.10 which doesn't officially support this CPU, but its voltage controller should in fact be capable of going as low as 1.3V (HIP6019BCB).

Should there be a problem running this CPU at 100MHz to get 750MHz?

So far I was unsuccessful. The computer turns on as soon as I switch the PSU's hard switch on (normally it turns on only after pressing the ATX soft power button), there are no beeps of any kind, and it does nothing.

I tried the slocket on "Auto VCore", auto FSB, 100MHz FSB, and forced voltage. Its documentation lists jumper positions for as low as 1.8V, which I tried. Despite it not being listed in the docs, I also tried 1.7V (the 5 jumpers correspond directly to Intel's VID). I even tried setting the mobo's CPU multiplier to 7.5.

I'm not 100% sure the slocket and CPU are okay, but as far as I remember they both worked the last time I used them. I did, though, have to struggle while removing the heatsink off of the slocket when to take out the previous CPU that was in there. There's also a chance the heatsink/CPU contact isn't perfect (if it matters anyway).

Any ideas or thoughts?

Check capacitors for leakage and the like. This stuff is getting long in the tooth.

 

[sheh]

The motherboard works fine with a 2V Slot 1 CPU.

you might need a bios update to recognize the cpu. see if you can find a hacked bios on the web somewhere that has the code for that cpu.

the board may have the functionality to run the cpu, but if it's not in the bios microcode to identify it, it won't run... hence it does nothing. but you should be able to find someone (hobbiest) to put in the code you need... hopefully

So OP, you've pretty much tried every conceivable configuration, right? I remember back in '04 I tried out a slocket for my PIIX4 motherboard (Pentium II motherboard 440BX chipset) and had terrible luck with those slockets (didn't work). So I promptly returned it to the ebay buyer who was noone too happy. I have no idea where these slockets work but from what I know, they don't work in most systems. You've got to get either the Powerleap PL-IP3/T SLot 1 Tualatin Adapter or just a Slot 1 Pentium III processor which while not so common, are a drop in made by Intel. It's really too bad Intel didn't try to more heavily promote those processors just like the Pentium overdrives of the early 90s because they offer an amazing performance boost and aren't limited by any hardware components whatsoever. Those Intel Motherboards with the 440BX chipset were great and while the IDE ports were lagging behind the times with the 33MB/s, everything else was up to par, supporting as much as 768MB of ram if you get 256MB LOW DENSITY memory modules.

Take a motherboard from 1998 with the 440BX chipset, pop in an Intel 1ghz 100mhz FSB Pentium III or a Powerleap PL-IP3/T with a 1.2/1.4ghz Celeron, add in 3X 256MB of ram, put in any fast video card you want and you've just taken a system from 1998 and brought it into the year 2001+. Shit, you could even put a Radeon 9800pro as that video card was the last high performance video card that could fit in an AGP 2X slot. It was great and it makes me sad that there really hasn't been anything like that since then.. I mean aside from the whole Pentium M processors being put into the ASUS P4 motherboards and all.

The BIOS (1014.3) supports this CPU, and I think all Coppermines. But even without support I think it would just complain during boot.

So OP, you've pretty much tried every conceivable configuration, right?

I can't easily rule out CPU or slocket problems. The easiest to try would be if I had another Slot1 mobo capable of running that CPU. The options I see: dead CPU (don't think it's likely), slocket didn't like the stress while I was trying to take off the heatsink (possible), slocket doesn't sit well in the slot (I vaguely recall in the past something like that), slocket is somehow incompatible, CPU's thermal protection kicks in for some reason, or mobo doesn't support it despite all indications.

I have no idea where these slockets work but from what I know, they don't work in most systems.

Discussions on the web indicate people did get it working. I used to use a Celeron 433 with that slocket.

You've got to get either the Powerleap PL-IP3/T SLot 1 Tualatin Adapter

Those Powerleaps are way too expensive (and I still suspect it could be something else because the voltage should be fine).

or just a Slot 1 Pentium III processor which while not so common

Yes, somewhat rare, or at least more expensive than its worth. The idea, so far, was putting to use random bits and pieces I had.

Take a motherboard from 1998 with the 440BX chipset

I think 1999ish is more likely.

Shit, you could even put a Radeon 9800pro as that video card was the last high performance video card that could fit in an AGP 2X slot.

I thought about putting on that P2B a 9500 Pro, but the fan's busted and anyway I'm somewhat partial to passive cooling.

Well I own both and I know the Pros and cons of both, the fact that I couldn't get the slocket to work in any system I tried, I knew I could never use it which is why I promptly returned it. It just wasn't good enough for the systems I tried it in so if you can get it to work in your system, I'm sure it's great since it's the cheapest option but it's also the least compatible option as well.

I think 1999ish is more likely.

The first iteration of the Pentium II was shipped either with a 440FX (May 1996 - Intended originally for the Pentium Pro, later used with Pentium II) or 440LX chipset, the 440LX chipset was made specifically for the PII and was released in August 1997 and was used in Pentium II 233-333mhz systems. In January 1998 the Pentium IIs with the 100mhz FSB were concurrently introduced with the 440BX chipset that supported a 100mhz FSB.

 

[sheh]

By the way, a Slot 1 Pentium 3 800MHz 100x8 1.65V worked.

Now, let's try to find a Slot 1 1GHz...

 

[gevorg]

Congrats. This thread blasted my thread resurrection alarm.

 

[stahlhart]

Be sure to check back in July 2012 to let us know how it turns out.

 

[sheh]

A few more months to go... who knows, maybe by then I'll get a 850MHz. Or better!

 

[sheh]

Damn. Sorry for being late. No, still didn't upgrade it to something better.

Oh man, does this post bring back memories! I had an old giant Dell case with a Tyan Tsunami motherboard. 440BX, 4x256MB RAM, and a ton of stuff in the expansion slots. Ended up tossing it all when I moved to another state. Sucker weighed a ton! Oddly fond memories of that system.
