Is my newegg AXIA 1.2 tbird a dud? Duron 600@900 stable for 10months on this mobo, argh!

[cvela]

I had been running a Duron 600@900 since last september on my trustee Abit KT7. With the prices of athlons having dropped so much, I figured it was time t retire my good old duron and get a tbird on my KT7. I decided to go ahead and keep my KT7 until the KG7 is a definite solution on the DDR platform. Since currently Im running 512mb of pc133 cas2 infineon ram and didnt want to have to toss aside so much memory yet.
Anyway I got my new Tbird came in yesterday from newegg, and I quickly disasembled the side my class and the PAL6035 heatsink clip from my duron and replaced it with the tbird. At 1.75 volts the thing would crash on boot into win2kpro, So I decided to clear the cmos memory and try again slowly adjusting settings per reboot. didnt work... I then started to up the voltages, to 1.775,
1.8, 1.825, all the way up to 1.8 volts where it finally ran stable! I thought at lease this chip would run 1.2ghz @ 1.75 volts! Well I will fiddle with it some more when i get home, I was wondering if anyone else had the same experiences.

thanks!

Is your power supply on this page? Alot of people are having problems with thier power supplies and higher clocked bird's. It's worth a look.

 

[Boonesmi]

is it actually a 1.2ghz or are you overclocking to get 1.2ghz?

and like blvdking said above if everything worked fine with the duron and the only dif is the cpu i would suspect either powersupply or a bios update is needed.

 

[cvela]

Its a Leadman powersupply 400watter, I purchased it a long time ago with my first athlon slot A @650mhz. I was having problems back then with the 650 and a weak 250watt powersupply, and bought this monster. My wife got this mobo and athlon and a leadman 300watter (on the AMD list).
I didnt suspect the powersupply since it was a 400 watt with tons of power I thought. And the athlon is a true Athlon C axia 1.2ghz cpu.

Thanks again,
Carlos

 

[Boonesmi]

have you tried running mbm or some other hardware monitor and see if your voltages drop below spec? if so its probably the powersupply, 12v really should stay at or above 12v

also what kind of temps are you getting?

what bios revision are you using?

 

[Fuzzmuncher]

It's a "C" cpu?

You have an Abit KT7? Not KT7a?

Someone please correct me if I'm wrong, but you're trying to force a 266mhz bus speed on a chipset that doesn't support it. Please let us know what setiings(i.e. multiplier & clock speed) your are trying to use.

 

[Boonesmi]

whoa fuzzmuncher, dang sometimes i get ahead of myself, i should have read the origional post better

fuzzmuncher is right, if you have a kt7 you wont get 133mhz fsb the best you can hope for is 110-115. the kt133 chipset just doesnt get much higher, even if the motherboard has settings for 133(which lots of boards do) it still wont run at that speed

you will need to keep the fsb at 100 and increase the multiplier to 12x (also make sure the chip is unlocked, it should be, i think most if not all 1.2ghz come factory unlocked)

the 1.2ghz (266 or C) was designed to run 133mhz x 9multiplier = 1.2ghz

 

[Fuzzmuncher]

Yeah Boonesmi, I had to do a double take too.

What threw me off was that cvela said it was stable @ 1.8! Cvela, if you need help, we need a little more specs. What are your settings?

However, if you did get your KT7 to run stable @1.8v, then I bow before you

Ok here are the details for my setup...

*Abit Kt7 Bios Revision for 5/11/01 "kt7zt bios"
1.2 AXIA (Line one: A1200AMS3C; Line two: AXIA0115BPHW" Athlon 266mhz
Multiplier set @ 12*100 = 1200mhz
Voltage @ 1.88 (according to Motherboard monitor 5)

*ATI Radeon LE Overclocked to 189mhz Timing Latency @ FAST, Memory @ Normal (with Radeon tweaker from rage3d.com)
- WIn2k Reg Hack for HyperZ
- Cooling fan mounted on heat sink from good old GLACIER 4500 I had on a PII 300@450 (It was famous at the time I forgot the code on it, I think it was SL3C or something PII's that were all the rage a few years ago)

*512mb staples infineon 7.5
-2*128 mb
-1*256mb

(all the chips onboard are Identical on all three chips so I figured they would work good, and so far no problems)

-Sound Blaster Live OEM

-Linksys NIC (I thought I had irq conflicts earlier so I swapped my original Netgear)

-3com ISA oldy 56k PNP modem

-Adaptec 2940 UW Scsi Card

- Plextor 12/4/32 (scsi)

- Plextor 32x (scsi)

- Pioneer Slot load DVD (scsi)

-IDE Iomega ZIp 100

- Maxtor ata 100 PCI card

-Maxtor 7200rpm 60gb HDD

-POwersupply: Leadman powermax 6100 ATX 400watt

I think thats it, looking at all the stuff in here I am sure that a weak power supply couldnt handle all this stuff along with the SUNON 60mm fan on the PAL6035 HSF, 60mm Exhaust (nidec FAST, Loud, And moves tons of air I had to install finger grills on both sides of the fan I had my finger nail cut once, and the second had my finger's skin pierced a little too deep! bleed for hours! haha so I learned), there is an 80 mm fan pulling air in the front and the power supply has an exhaust and inhaling fan too.

MBM 5.0 says that my voltages are stable...

12v = 11.23
5v=4.91
3.3v=3.36 (3.4 set in bios)
1.85v=1.88-1.84v

OH and my OS is win2k PRo w/ SP2... Made a streamline copy and a clean install about a month ago..


thanks!

Well, I just popped the 1.2 tbird out of my system and replaced the trustee old duron @900... I was getting good temps on the tbird @1.2... MBM 5 was reportin 42-43 celcius.. Under load of Seti it shot up to 50 but ran stable, in idle it was like 38 degrees. These are almost identical to the duron. Anyway my voltages across the board are the same as the tbird. I just started to get blue screens like crazy all of a sudden, HIVE corruptions, and other blue screens I could not decypher. Is it safe to say that maybe the chip might be bad?

[BlvdKing]

Does a friend have a Socket A based computer you can test the CPU in? That's how I determined that my Duron 750 was good.

 

[cvela]

the only system that I was able to test the processor on was a compaq system. So I was limited to like 900mhz since there was no multiplier setting to be found. I ran the system for 4 hours with just a screensaver and it worked fine, So I decided to test the power supply, and heatsink. So I replaced the powersuppply in my system first, with the compaqs,and it appeared to work fine. Then the lock ups started up again only less frequent. I then tried the Taisol heatsink and everything ran smoothly.

When I switched the power supply back to my old one I go the problems back though, so Im sure the heatsink is not the problem since my original alpha and the taisol have the same temps almost. Im pretty sure its the powersupply, even though the voltages didnt fluctuate that much different on mine than on the compaqs. Oddly enough for some reason I think the chip is at fault too, but again the problems still manifested themselves with the new power supply.

thanks

[BlvdKing]

Many people, including myself, are having problems with power supplies lately...

Keep us updated.

 

[Dill]

IMO your voltage readings seem low. Especially 11.23 on the 12 volt rail..eek..

 

[Garion]

Cvela,

I'm not really adding any new info here but you're running your chip at 12X100 to get 1200 out of it.. The chip you bought is a 266FSB version, designed to be run 9X133.

An experience overclocker I am not, but are these two multiplier/clock settings really equal and do they run the same way? Might be a better question for someone more experienced, but it seems like a logical question to ask.

- G

 

[cvela]

I thought I had researched enough before I bought the 266mhz version. But maybe someone else on the board can verify that I dont have to modify the chip to make it run at 200mhz FSB? Im begining to think that may be a problem, I wonder if there is a pencil trick to making the chip believe that it is a "B" version athlon @ 200mhz fsb?

thanks
carlos

No.. the C will run fine at 100 mhz, as will the B run fine at 133 mhz, providing your chipset is adequate (133a vs 133)..

 

[LongTimePCUser]

12 *100 should be just fine.
You might try removing some of the memory from the system and see if that makes a difference.
The low voltage reading for +12 volts could be causing the problem.
