What's the matter with my AXIA Y and KK266?

[Zak33]

Why has my AXIA Y started giving me stress?

It has been running A OK all week set to 11x133=1466
It ran that at default voltage...........so I upped it to 11x140=1540.....needed a bit more volts,
so went with 1.85

Was fine......have run it like that all week

Until today when I decided to knock it BACK DOWN to 11x133 at 1.75.....no point stressing my new investment!
Would not boot at all, no POST!!!! AHHHH
I have an SK6 and a Delta on it with Arctic 2 Silver paste..........do I need to re install that?

It will not POST at that speed even with 1.85 volts..........weird huh?

So I let BIOS go back to DEFAULT (which is 10xFSB ) and FSB is 133.........it ALWAYS posts like that.

Let it boot into Win98SE no hassle..........restart..........NO GO!!!

Have to unplug the PSU and then its fine at default again!

Am confused and sad......got a KK266 mobo.......

Is it likely to be my CPU or Heatsink

Or is it my PSU? (300W ) which has been good as gold ALL week........

My Radeon 64mb DDR? I got fans all over.......two run off headers on the mobo...is it them?

I have SCSI PCI card and SCSI HDD and CD

They were fine at 140 FSB

So why no POST at 133

Pls help!!! ;(

Clear the cmos and see if that works. there's a jumper for it down by the battery. you'll have to redect your hdds and so on, but that's no biggie. It also could be your pwr supply too. 300W ain't much once you get over 1.4 GHz. What brand is it? Is your cpu unlocked or did you have to close the L1 bridges?

[Zak33]

Its an AXIA Y from OcUK............it was fina again last night after faffing with Default BIOS......but this AM ....no boot...had to hit power at the back of the PSU and then switch back on......luckily it always comes back yo default which is 10x133

Pain in the @rse huh?

Gonna check my PSU name and branding today!

Case back off..........will reset CMOS too

Cheers

Keep em coming!

Zak, when you say pre-unlocked, it was done by the seller? What is default speed? If the pencil trick, it could be needing some conductive pen work or the window defogger paint to make it permanent. Pencil stuff can be hap-hazard and wears out eventually. If 1.2 or higher, probably factory unlocked and it's not the cpu. Random reboots, and booting back to default speeds is also good sign of power supply problems. What is your +5.0 V reading in bios or MBM? Anything lower than 4.8 V can give your problems for sure. Also, could be memory timings may be a bit too fast.


good luck,

Sethpa: I am interested in your PS experiences. Didn't you upgrade from one AMD approved PS to another? My 1.2 AXIA really gets quirky over 1400 and shows similar symptoms to the ones in this thread - weird shutdown, no post after bios reset etc. Running at 1.4 right now and showing 4.88 on the 5 volt line, 1.84 core. The strange thing is that my core is set at "Auto" for default and is .09 high. If I set it manually, the result is always .07 higher than where I set it.

My PS is a High Power 300w AMD approved for 1.4. It was cheap.

Zak: As I understand it, the KK266 will always start to POST at default voltage for CPU and then mod the voltage to what is set in the BIOS. This evidently creates a problem when you start to push things to where the CPU needs that extra jolt to wake up. You can change the default voltage that the cpu tells the motherboard it wants by doing the pencil trick on the L7(?) bridges. There are articles at Tom's Hardware and AnandTech on how to do it. I have not had the time to try this myself, you may want to research it.

Lmandrake, I went to the 330 watt Enermax, and still had similar problems. RMA'd that one for the 465PE-VE 430 watt Enermax. No more problems. But this is with the Epox 8K7A, which is notorious for PSU problems, ie; low 5V readings. It seems the 2 phase power handling this mobo has, is not as stable as newer 3 phase setups, like the KT266 Epox board, the 8KHA. Another thing, at default Vcore setting of supposedly 1.75, I get 1.82 V in bios and MBM. When bumping up Vcore to 1.85 I get 1.92. Accuracy of the readings? Who knows? SiSoft Sandra gives somewhat different reading, some higher, some lower.

Who would have thought a year ago, that a power supply could make or break a stable system? All I can say for sure is, the 430 watt power supply fixed my reboot problems. I still can't get above 150 FSB in memory with any stability, yet people with exact same memory setup often reach the 170's and higher with this mobo! But that's a whole 'nother subject.........

Mandrake you are on the same wave length as me today........I went and got me some defogger repair paint and a bIg magnifier lense. Tomorrow we shall see

I have thought about the PSU....... maybe I am wrong but as it ran all week last week at 1466 no hassle, then I upped it to 1.85 to get 1533.......once again no hassle...ran for 2 days, heavy games etc..then I try to take it back down and it is unstable.........I think it is the initial boot up voltage as you said....it has burned in to the higher volts........kinda the electrical version of getting use to easy life at high volts.
I got it to run last night at 1466 once......and once there it was rock steady again

I will try the higher voltage mod tomorrow to get it to boot up at 1.85 from the off, not just when BIOS gets controll

Then I shall try the PSU if it doesn't work

LISTEN PEOPLE...THANKS FOR HELPING....ITS NICE TO KNOW YOU GUYS ARE THERE!

[Zak33]

SORRY MAN..DIDN'T MEAN TO MISS YOU OUT.......

OK I read the bottom post first...DOH!

I thought I was buying a pre unlocked CPU done at the factory........but I don't think I got one of those.
a: Its a 1gig AXIA Y not a 1.2
b: The cute little black plastic case it came in was full of black particles..never thought anything of it, just cleaned it
c: The sticker they had put on it saying 1.4 (I guess the speed they had tested it to) was on the L1 bridges and I took it off cos it worried me as I didn't want it faling off at heat and blowing into the fan
d: I guess I took off some of the "whatever it is" they used to unlock it...PENCIL I GUESS

I truly thought that it was Factory Unlocked..maybe not.

So tomorrow I take it out, clean it up, check to see if I need to do the defooger repair paint job...and THEN the volt mod that Mandrake said about

Woohoooo
Not boring this is it.............by the way its at 1333 at the mo and NO HASSLE as it is default volts

Hang on.........I remebered....I checked it out last night at LOADS OF UNDERCLOCKED SPEEDS....like 6x133, 7x133 etc.........it never ever failed....so it ISN'T the unlocked bridges at L1 is it?

Later

[Lmandrake]

I assume that when you underclocked it, you checked the display at post and in Sandra or MBM to see what speed it was really running at.... If you did succeed in underclocking it, then you are not multiplier locked.

LMK how things turn out. I got into this T-Bird thing involuntarily when my out of warranty BX board blew up. I spent way too much already and have no desire to spend real bucks on a big old Enermax.

[Zak33]

As with all things PC it is never the same one day to the next!

For example....tonight I coulc not UNDERCLOCK it either!

And then I could.and then I couldn't

Piece of bloody rubbish....I am taking this baby apart tomorrow!

Got the conductive paint ready...and the CHAINSAW!

I will keep ya posted...literally!

PS...upped the FSB tonight and it went quite high..........I got cack memory...(not Crucial etc) but it hit 143 FSB no hassle

So it COULD BE BOTH THE MULITLIPER AND THE VOLTAGE BRIDGES!!!!

Oh boy...something else to look forward to!

[Zak33]

I took it all apart again..............

a: It was pencil unlocked, so I painted it with Rear Defogger Paint repair kit.........heart in mouth that job isn't it? While it was going on with a needle and a magnifier I was shaking more than I have ever shook. Stupido! Anyway I waited for it to start drying then cleaned around it with the needle, pulling paint in the direction I wanted it. When it was dry I scraped in between the contacts to keep it all seperate

b: I modded the boot up voltage while I was there.......bit more silver paint, up to 1.85 by joining the last one up so they were all connected at L7. THIS IS WORTH DOING.MORE ABOUT THAT IN A MO!

c: Shut eyes, sobbed, whimpered, Power ON

POST....BOOT

Loverly jubberly! And the voltage mod has worked no doubt........it will POST and Boot to SCSI before locking up at...............

1.6 GIG !!!!

It would never have done that before, even when the pencil was still working, I know I tried!

So the voltage mod is WAY worth doing.........even if you then knock it back DOWN in BIOS for a slower speed!

Nice people, you all helped, so thank you, cheers a million.

Back to Max Payne now!
