Re: Motherboard loses time?

Oui, I know I was tired when I posted but still.

Posible problems:

Battery, if it's low quality, does'nt matter if you get cmos checksum errors or not.

Addin cards.
These can reprogram irq0 and setup vectors with onboard roms.
Most likely cards to do this are crappy pci based capture cards.
Remove them all to be sure.

Cpu.
You may have to replace it with a better batch.

Bios.
The bios is a main factor, it's the one that's supposed to setup irq0,...

Re: Motherboard loses time?

Try a better battery, 2032 type.

Also yeah, the rtc is in play when the rig is off.

When it's on these come into play:
CPU.
BIOS.
IRQ controller.

The irq controlelr is liekly to be a 8253 like chip.
Which are easy to program.
Though some info is very very hard to locate, but I know how to program both the tREF and the irq0 timer.
I've done so succesfully.

Irq0 however gets reset when booting windows, even winpe based os'ed I'm afraid.

Re: low or super low ESR + impedance caps

Double post, I forgot to ask about something that trodas may of not noticed.

In some rev's of the board, specificly the later china rev's,there is a cap between the mosfets for ram slots 1 and 2.
(Actually backwards, since slot 1 is the last slot from the cpu and vise versa but let us not get into that).

Anyways it's a hack job sorta thing.
Like board companies do and all after they find some sort of flaw with the initial design.

I was wondering if anyone could tell us what sort...

Re: low or super low ESR + impedance caps

I see thanks .

Sorry about the classification erros, where I said os-con's...
I'm learning though, I should of called them solid polymer or ceramic.

I would assume you're talking about the ones around the memory slots.

There is a few spaces that don't have anyhting but I'm not sure as what they actually affect yet.
Later on I'll take out my board, write down the rest of the values, and take a look at some traces to see what caps belong to what circuts.
(Edit:,...

Re: low or super low ESR + impedance caps

Hey trodas .
I'm gonna join this thread, even though I allready posted in the sister thread in dfi-street.

These guys have alot of knowledge, I would'nt mind asking them ?'s and all, I hope you don't mind .

I got the same board guys.
Mine was made in china.

I can post specs later, I'm 100% stable(prime, superpi, s&m and memtest at 275, 550mhz fsb, 250x10 prime and everything stable @1.725v vcore)

I've been planning on doing some of the hardware mods, I've had...
