No Gigger for me?

[xortam]

Can't seem to get my system up using the new PS. W2K starts to boot up but eventually the boot drive light goes solid and I get a STOP error of "Inaccessible Boot Device." It was booting off of that drive fine until that point in the boot. This is always repeatable. The BIOS shows "ignore" on the -5v line and the 3.3v line is a bit high at 3.5v. Everything looks correct (hard to connect it wrong).

[xortam]

Put back my old PS and noticed similar voltage readings in the BIOS. Odd. Anyway ... system boots up fine with the old PS, so what's up with the new one?

[Greebe]

Xor, what are the specs on each? I've noticed for example a typical 300w supply varies as much as 10 amps on the 5vdc and or 12vdc supply rails. Depending on the setup, that can be the difference between success and failure. The power specs needed are currently too loose in my book to ensure proper opperation... esp in the extreme

PP&C make some of the best supplies and do reccommend them, but lets hold off on the replace another for a moment.

If I had to guess, the newest PS can't supply enough current at startup cleanly (overload induced ripple most likely). That being is it possible for you to use both in the same case?... wire up together for a trial run.

Your "VOM" what is it... ie brand, make, M# some specs... need some accuracy here.

[xortam]

The VOM is just a "toy" (A.W. Sperry SP-5A) that I use for rough measurements ... wouldn't do us any good. The case only has a spot for one PS but I could temporarily rest the second PS on top of the open case. I would need some adapters or somesuch to tie these together (I assume serial, its been too long to remember). It would be easier for me to just go out and try the 350 TurboCool. The new PS draws 8 vs. 7 amps and has tighter regulation on the 3.3v line.
<edit>
P.S. The Plextor burner and NEC CD are in a separate SCSI case so they're not drawing power. I also tried the new PS w/o the DVD connected to the power.

I went out and exchanged the PS for a 350 Turbo-Cool and it is about as stable as my old PS. I gave it the old "Greebe" test and it eventually locked up. To explain ... animated GIFs seem to easily lock up my system, Mike's avatar especially. I've been running w/o animated GIFs for a while to help stabilize my system (which it does considerably, but not completely). This new, bigger PS also sometimes POSTS with a PM error, which I can bypass by disabling PM. Looks like I'm going to have to give up on this experiment and get my old 850 back. My buddy will have to sell this rare CPU on E-Bay or something and get another 850.

P.S. Another odd thing about these Turbo-Cools is that they cause my system to start to POST faster.

[xortam]

Not quite ready to say die after all. Went back and exchanged the 350 for a 425 which has tighter regulation on some of the other lines. Up to 185 super freakin bucks now (plus tax) so I'm starting to hope it doesn't work so I don't incur that expense. One more time ...

[Patrick]

Have you gone insane?

185 super freakin bucks now (plus tax)

Just for the power supply ??!!! For that kinda money you shouldn't even have to plug it into the wall.

And it wasn't any better than the 300w that came with my case! Looks like Lite-On makes pretty good stuff. The Lite-On PS is better ventilated (all sides) than the Turbo-Cools and its mated to fix my Lite-On case snugly which other PSs don't do. I'm going to try the latest Beta BIOS and then call it quits.

[KvHagedorn]

The power supply is possibly the most important part of the system, like the foundation of a house. My 450 was more than $200, but my system is much more stable now. I don't really think its so extravagant.. your computer should certainly work now, xortam. Perhaps there was something other than the power supply causing the problem.

[xortam]

The problem is I'm trying to run a 1 GHz processor on a MB that was designed for a processor with a maximum frequency of 600 MHz. It just gets to be a matter of luck to have the right mix of components that will let you push those timings to the extremes of their tolerances and still interface correctly. A clean PS is only going to give the MB the best chance it has running at these extremes but it still can't make up for the limitations of the system. I still have to try the latest Beta BIOS but I'm not holding any hope for that to work. The system has continued to stay up after disabling web animation but I've had it stay up for days with my old PS. I'll bang on it some more and try my other OS installs to be sure (always tested them w/ the other setups). I remember seeing someone with my MB running a Gigger posting on an ASUS forum so I know its been done. My MB does better than my friends P2B-LS (same Rev.) You throws the dice and you takes your chances.

Since your mobo wasn't designed for using a CPU like that, why would you even try??

I checked your mobo on Asus' original site, and you wouldn't even be able to get beyond a P2-400 according to them... not even with your latest BIOS update !!

Ofcourse Asus' original site is way out of date according to you, so you won't consider them... so I checked the German Asus site, and guess what? The maximum an Asus P2B-S can take is the same as what the original Taiwanese site said...

lol...

Your P2B-S which means onboard SCSI, went from a minimum P2-233 through to 450MHz, no MENTION of a P3-600MHz and only your SCSI firmware gets updates through 2.20 to 3.0

Leave your board alone and be happy with what you have, to give advice next time on someone with a P2B mobo ( ) or go out and buy something new, so you won't have to give everyone flicking advice (holding hands with your buddy someone), and then find you have to ask advice here from us same people !!

In plain other words... Your board can't take it, live with it or crack it up.

For fun and adventure, Jorden.. he's seen it done and wants to puzzle out why. It's a good motherboard.. no, an excellent motherboard, and I can see why he'd want to try and make it work. Another friend tried this on his Abit board and it didn't work.. wound up getting a new 815 board for his 1 GHz P3. This is an Asus, though.. much better hardware. I feel your pain, xortam.. I got my motherboard a couple of months before they did the hardware revision on it to make it accept coppermines.. oh well.. it should serve fine as a dual P3-600 for awhile yet. When I upgrade I will use it for something else, no doubt.

I'd keep the power supply though.. and maybe sell the lot and get a Tyan Tiger MP!

Put the bottle down Jordey.
Saved for posterity ater he sobers up and deletes this garbage (or wises up .... nah, won't happen) ...

No pain for me. I was perfectly happy with the 850 running on my system (oh why did I try? ASUS say's it can't be so. ) My buddy couldn't find a FC-PGA Gigger so he bought a slot 1, against my directions. He's the one stuck with this processor that neither of us can use. I was just helping him out (and gaining 150 MHz) by swapping him CPUs. He'll land up selling the Gigger and buying another 850 FC-PGA for me. I'm not in a hurry to replace the system yet since I utilize the on-board U2W SCSI along with my SCSI RAID card for some extra performance from having an additional bus. I keep my systems for a very long time. I'll see what the MB/processor market looks like next year before I consider a replacement.

Hi Jord,

if I had followed Asus' list of supported CPUs, I'd still be stuck with a completely outdated processor ...

I'm not 100% positive, but I think, I encouraged a lot of people in these halls to ignore that particular compatibilty list and Xortam's 1Gigger seems to the only CPU so far that still refuses to run stable.

Therefore, I see absolutely no reason why anybody should not try to use a CPU that is not supposed to be supported.
