Another Deer In the Crosshairs

[bgavin]

Last night I responded to a family friend machine that died. The PSU showed good on the Antec tester, but the board would not power up. Still dead after swapping in a new, known-good PSU.

Uh, oh. Dead board... gotta take a peak into that DEER piece of crap PSU. Sure enough... bulging caps in the PSU.

wowee thats news?

Re: Another Deer In the Crosshairs

I'll bet that the DEER had bad caps on the +5V standby circuit?

pull the trigger.
12ga rifled slugs work best.

Sorry, I don't like guns: I'd suggest bgavin to hire a karate black belt smashing in pieces that real crap.
I hope the damage just stopped at the motherboard.

Re: Another Deer In the Crosshairs

Well i love guns, especially this one:

i think it would be adequate fore this job, may be a little overkill .

bring it over here.
when i am bored,pissed,or i just need exercise i will crush it like i do most cheap psu before i toss them.
keep my hands in shape.

Re: Another Deer In the Crosshairs

drive over it slowly and appreciate the sound

I favor the big hammer approach:

If bgavin can find a karate kid, both your hammer and Willa's 4-wheeled Hummer will be fine

Re: Another Deer In the Crosshairs

humm gonzo....too expensive on Ammo mate.... but I like it
how would you go reloading for that...yes that was a joke


So the Deer scores another MB
not good Bgavin, bet they didn't take that news too well.

Re: Another Deer In the Crosshairs

I've been gone several days with a torn up rotator cuff in the left shoulder...

It is soooo refereshing to come back and feel the love that everbody has for these DEER pieces of merde. Thanks for the chuckle over the many ways to cap a DEER.... I own a Remington 870 DEER gun anyway, so that is probably my best 12-gauge solution. Amen to slugs and 000-buck.

The fatality was a PIII-800 with a 440BX chipset. I have another PIII-1000 440BX floating around, so it should be a 1:1 swap without further issues. The client is a nice little ol' lady who really likes the machine just as it is. She does her dial-up thing, and it works well for her.

RIP for poor BX: it didn't deserve this death.

[OT] Bgavin, your P3's fsb is 100 MHz? BX can handle 133 MHz fsbs, but this forces Agp bus out of specs at 89 MHz and, of course, cards don't like it much. [/OT]

Re: Another Deer In the Crosshairs

Depends on the board. Some boards left the BX to do 100MHz FSP with very little more than that due to the AGP divider, while other boards allowed 133MHz and the AGP would divide to compensate.

Excuse me jonny, I don't understand your sentence: there are some old boards with limited frequency oscillators and limited fsb choice (e.g. my Asus P2B rev 1.02 can ran the fsb at 112 Mhz, but not above), but most (if not all) of more recent ones allow, though not officially, 133 MHz. This is a board/oscillator limit.

The Agp divider limit is another one: in 1998 Intel released the 440BX as Pentium 2's chipset of choice so it could run the fsb at 66 (for core Deschutes P2) and 100 Mhz (for Klamath ones); since the Agp 2x frequency is 66 MHz, the BX has only two AGP dividers: 1:1 (intended to work at 66 MHz) and 2:3 (at 100): despite the presence of a 1:4 PCI divider which allows a 33 MHz PCI bus even with fsb at 133 MHz , the lack of a 1:2 divider later prevented Intel from offering official 133 MHz support.
If your board, your cpu and your memory can handle 133 MHz (read board as "oscillator": the chipset can handle without any issue this frequency), then your Agp card has to run at (133 / 3) * 2 = 89 MHz, 33% over specs. Not all cards can handle this: I remember first nVidia cards (TNT, TNT2 and Geforce 256, 2 and 3) were capable to.

The Agp bus is the real drawback in overclocking BX boards, so I asked bgavin if his Coppermine is a 100 MHz one just to be sure the board will run on spec.

Right. I'm not contradicting you. All I'm saying is in my experience there are boards that will do 100/66 while others will do 133/66. Some boards will actually have a manual AGP divider setting in the BIOS where you can set 3/2 or 2/1 AGP divider to achieve 133/66.

All right, but 133/66 boards aren't based on the BX: they employ other chipsets.

Mmmm... I seem to remember fairly vividly some BX boards at the end that would do 133/66. I'll research.

Re: Another Deer In the Crosshairs

well sort of know what you guys are talking about and do remember quirks with AGP & FSB ,anyway found this.

We all know that the BX chipset may be old but goldie, we also know that it doesn't offers the proper AGP divider for 133 Mhz support and overclockers. Under the P3V4X's bios, you can have a choice of setting your bios manually through the Dip switches or through the Bios setup. The AGP divider is automatically set to match your FSB appropriately, eg. 133/66.

I dont know as I never really got into this thing but hope that makes sense
all I can assume is possibly some boards may have catered to the issue in some way.
(this seems likely to me if people were OCing and it was possible to do)
