I just got a Powerleap adapter. It's PCB model and revision is: PL-iP3/T V 2.0 It has a Celeron 1.4Ghz CPU attached to it, and a solid copper heatsink which looks about 11 - 12 mm thick. I'm thankful it came with a power cable, because it looks "propriatory" and I don't have one with that particular shaped power plug.

I am testing it in an Asus P2B (3 ISA slots) mobo, with the latest Beta BIOS. At first, it complained about the CPU, and told me to adjust some settings inside the Power Management section. I set some of the Power Management status fields to "Ignore". It didn't like the CPU fan speed. It also didn't like the core voltage setting of 2.08. I presume that's an error, and it is running at the Powerleap's default jumper setting, which is 1.550 - 1.570v

I just got it installed, so I'll mess about with it for a bit, then post back with some observations and benchies...

Edit: I'm using a Voodoo 3 AGP card, but it's a Gateway card and has a lower clock of 143 I think, and not 166.

Sandra CPU score = 3854, 1881
Sandra Multimedia score = 7436, 9022
Pcpbench mode 103 (800x600 LFB) = 94.1
3DMark 99 Max = 6773, 18654 (V-sync may have been "on")

Edit 2: I removed the Gateway Voodoo 3 AGP card, and replaced it with an ATI Radeon 7500 AGP card. New benchies -

Pcpbench mode 105 (1024x768, LFB) = 65.8
3DMark Max 99 = 6351, 18890
3DMark Max 99 (v-sync="off") 6421, 18841. That's interesting - the Voodoo3 card beats the Radeon 7500 card.

Edit 3: I removed the ATI Radeon 7500 card, and replaced it with an MSI nVidia GF Ti4200 (nv25) 64MB AGP (4x) card. Unfortunately, I couldn't retest my "new" Zalman cooled Ti4200 card, because it simply won't fit in to the AGP slot, due to its very large "double-sided" heatsink getting in the way of the corner of the slot 1 cartridge Powerleap CPU. I ran 3DMark 2001 s.e., on default settings, and got 7567.

This is why the haters cut down the Voodoo3, it only does "16bit" color. Run the benchmark in 32bit color to see that Radeon shine. 😵

It might not be an error. The voltage regulator on the earlier revisions of the P2B didn't support the lower voltages necessary for those Tualatin chips. But, it shouldn't be a problem anyway, as the Powerleap thingy has its own voltage regulator onboard to compensate just for such cases.

As for the V3, if it's running at 143mhz, that would make it a V3 2000. You should be able to overclock it at least to the 166mhz speed of the V3 3000 without much trouble at all, and many of them would even do 175mhz.

Yes of course! I tried to increase the color depth inside 3DMark 99 Max, but because I don't have the "Pro" version, it wouldn't let me. Instead, I ran 3DMark 2000, and set the color depth to 32-bit, and got 5273.

That's a good point. However, the P2B I am using is a later revision - 1.12. I believe it may be the last (or one of the last) revisions they made.

Yes of course! It must be a 2000 model, as you correctly point out. Thanks for that. In fact, I vaguely remember OC'ing it to 166 a month or so ago, without any trouble.

Hm, maybe it has to do with the way the regulator on the Powerleap card works, then... like, maybe it tells the motherboard to feed it 2V in order to have headroom to run the voltage regulator on the card? Just a guess, but it would make sense. As long as it works, though, I guess it doesn't matter how.

Radeon 7500 should be a lot faster than Voodoo3. Radeon 7500 is more like a Geforce 2 Ultra but with better everything from a quality standpoint. 😀 Is that 7500 clocked at 290/230?

Still, you'd want to choose the GF4Ti over that 7500 every time. The Voodoo3 is better too for a lot of old stuff.

Unfortunately I don't know how to see what the clock values are. My trial version of Powerstrip has now expired. I tried RivaTuner, but it wouldn't show me what the clock values are. The ATI control panel doesn't tell me either. I would like to find out what these values are. Can you recommend a utility please? Thanks.

Congratulations on joining the Powerleap + ASUS P2B club. You've hit retro nirvana now.

Everest Home Edition should work. It's free and works great with hardware pre-2005 or so (when they stopped working on it).

I was really pleased this photo came out legible! 😀
I just reran 3DMark 99 Max, v-sync="off", default settings = 6390, 18691

you chopped off the RAM clock. 263 MHz core isn't far off of the 290 MHz of a retail ATI-built 7500.

oh and btw, you should try out Alt+Print Screen and paste into Paint or something. 😁

Oops! 😦 The RAM clock is 200.
(My internet PC has no working FDD at the moment - must fix it!, and so it's not possible to upload screenshots from test machines.)

Edit: I just realised, I could either use a USB flash drive, or I could get a CD/DVD Rewriter. I wonder if Rewriters work in Windows 98?

Edit 2: I think I'll just use a USB flash drive. Maybe in conjunction with an extension cable, so I don't have to keep pushing and pulling the drive out of the back of the mobo, as it's a bit awkward with the mobo sitting on a cardboard box "work bench", and various wires and plugs and stuff everywhere at the back.

Just for a bit of fun, I was thinking of setting both the Powerleap adapter and the Asus P2B rev 1.12 mobo from 100 FSB to 133 FSB. Good idea or bad idea? To set the Powerleap's FSB speed, I need to remove both JP2 and JP3 jumpers. I wonder if I also need to adjust the Powerleap's CPU core voltage jumper as well? To set the P2B mobo's FSB speed, I think I need to set the four FSx jumpers (FS0, FS1, FS2, FS3) from its 100.3/33.43 setting, to the 133/33.3 setting. Before I go ahead and try this, any thoughts please people? Thanks a lot.

Edit: I don't think this will work. The Celeron 1.4Ghz CPU attached to the Powerleap adapter is 100 FSB. Perhaps I need to replace this CPU with a 133 CPU?

Are there any "upgrade options" available for this Powerleap unit, in terms of upgrading its heatsink? I would like to try attaching a larger one to it. There's plenty of room for one. I'm new to these things. I think it's socket 370. Do I simply hunt about for any (heavy copper) socket 370 heatsink? I'm not sure about this, but could I try a socket 462/A heatsink? (Are these two types of socket interchangeable?)

There's nothing wrong with overclocking on a Powerleap adapter, but you'd be better off trying for 112mhz, as a 1.4ghz Celeron probably isn't going to like the 1.86ghz that would result from 133fsb. It should have no problems at 1.58ghz/112fsb, though.

Thanks.
But would I be even better off with one of these? SL6BY. It runs at 133 fsb. If I set the Powerleap's jumpers to 133, and use a SL6BY, in conjunction with the mobo's FSB jumpers being set to 133, then am I correct in thinking that that equates to no OC'ing at all?

No, you wouldn't really be better off, and no, the board would still be overclocked. Remember, the 440BX didn't officially support 133FSB, and at that speed, the AGP would be running at 89mhz rather than 66.

OK thanks. I'm going to try: 1.58ghz/112fsb.

I haven't OC'd either the Powerleap or the mobo yet, or both. (Actually, I'm not sure which one(s) I have to OC. Maybe I just leave the PL set to 100 fsb, and then set the mobo to 112 fsb. I expect that's it.)
Anyway, I tried a Radeon 9800 Pro 128mb in this non-OC'd system, then ran 3DMark 2001 s.e., settings completely maxed out (incl 6x AA). I get 6265, which is excellent. Pcpbench mode 105 (1024x768, LFB) = 67.7.
