believe me, it becomes a mess, I already had the pcb finished so i modified it, but when i get the real MAX pcb i`ll desolder everything and solder it on the Max Pcb.

(had to cut a couple of connections and make some bridges)

So I guess we'll better wait till we hear something from Xavyer/Mastero.

I think they must of been a bad batch like everyone is saying.

My 3.3 AND 5.0 lines would drop to crap, when ever I plug in the CPU. Without a load, it worked fine.

So instead I used the old MK3.5 board (it had max chips on, and it worked fine).

So i've changed my MK4.0 board to the MAX way, and so far so good. (I only have one chip this moment, but still boots up my EPIA M board fine).
12V = 11.8
5V = 4.8
3.3V = 3.2
CPU core = 1.325

So in short.
National = bad/cost money
Max = good/free

I doubt it. If this many people were getting bad chips it would certainly mean quality issues at nationals end that would be showing up with other customers, customers who are paying a lot more than we are and would raise a much larger complaint. Rampant issues like this just don't exist on products that have had a long life and especially on a process that was long ago perfected. I didn't analyze the ramifications of what you are trying to do but in general you can't just take 1 switching regulator and drop it in the place of another regulator without a serious analysis of the circuit.

hi, guys i,m new... just planned to start my carputer a month ago.Gathering all the hardware ,software and information i need. stumbled on sproggys power supply that led me here.

just have some simple question... i,m running a pentium mmx 133 ,1gb hd ,cd rom.soundblaster awe64 ,aopen mobo.old stuffs.

my pc doest seem to need the 3.3 v , and i,m not sure but does that auto shutdown and standby mode feature applicable in my case?

so should i built the mk 3.5 or 4 ? or just build the original sproggy(have problem with getting my hands on the transformer) (http://www.mygizmos.net/frames/index.html sproggy)

SOrry if i sound stupid. hope u guys can help me out.... thnks hope to hear from u guys asap.

Brother you sound like you have a at board ..... and i dont think SDC will be any good with AT board ... so suggestion is first get your hands on a ATX board ... it will make a lot of difference ..

AS for the PSU .. go for the MK 4.0 (WITH MAX CHIPS)

Mastero

silentarchangel · 09-26-2004, 04:18 AM

what do you mean a lot of difference? like how?.. what board would u suggest?.. but your MK4 with max chips is not complete?.. where are the pcb and parts list? i,m trying to run the carmp3 with minimum hardwares just aslong as it runs my win95 with winamp its good enough, and i even got an awe64 soundcard... thanks for the reply
oh yeah and one more thing... what is that sproggy type item on your component placement ? thank you for your help its really kind of you to help those of us that arent that super genius

Soul · 09-29-2004, 03:55 PM

silentarchangel if i where you i would buy a via epia motherboard
it has everything on it, are small, doesn't cost that much and works good with mk4.

just got my maxim samples in the mail, waiting for the PCB to arrive now

hcker2000 · 09-30-2004, 01:53 AM

Mastero: how much are the MK-4 kits? (in usd if u would please). Or how much would u say all the parts cost?

silentarchangel · 09-30-2004, 08:01 PM

of course mini-itx mobo who wouldnt wanna use that for carmp3?
but im lookin for something simple ,cheap i already have a cdrom a HD a soundcard awe64 the lcd the remote all i,m missing now is the power supply.
and i wanna run win95 which has a better bootup speed.

thanks for the help anyway

MrPerfectionest · 10-01-2004, 06:34 AM

get Win98 lite...more stable and probably boots faster than Win95
