A7V133 probs

[MechCD]

Only certain mult and fsb settings werk! 140 x 10 werks, but 133 x 11.5 won't. 140 x 11 boots, and 133 x 11.5 won't

If i set the voltage to auto it werks a lot more often than if i set it manually. Could this be one of those lower voltage = better overclockin things?

Another thing. 133x 11 only werks at auto voltage. If I set it to 1.85 i get a cool kernel panic in linux ;) (Aiee! Stopping interupt handler)

But at auto voltage its workin' fine now.

AMD 1.3ghz tbird (ahja stepping?)
Asus A7V133 rev 1.04 board
assorted PC133 CAS3 ram
Geforce 1 SDR

Correct me if I'm wrong. Isn't the 1.3G a 100FSB chip? So initially it's trying to boot at 13 X FSB, until the BIOS takes over. I have A7V133's and never encountered this.

Also about your voltage problem, I can't run at a higher voltage stable either. I haven't had to though unless I try to push it past 1.5G, which doesn't work too well anyway.

Sorry, that's all I can think of. :(

Yup it be a 1.3ghz 100fsb cpu. Cept there is no 13x, so 12.5x works when at 100fsb. Right now its ok at 1466mhz (i think 133x11)

Auto voltage actually auto voltages! It upps it as the cpu is nstable! at 1466mhz it upped it to 1.80v! Smer ones those Asus boards are , cept when it comes to multipling 133 x 11.5

Problems at certain multiplier settings is indicative of one or more suspect L1 bridge links.....

[MechCD]

But it was factory unlocked.........



Also, any of you a7v133 (or even a7v), did your jen jumper come without a jumper? I found that out a week ago. That caused it randomly not boot.



The JEN jumper is for enabling jumperfree mode or using dipswitches. There needs to be a jumper on 2 of the 3 pins at anytime and mine didn't :( now it does :)

I thought mine came with JEN set to jumperfree mode. I'll have to check now.:) I'm sure that no matter what the multiplier is set to, the board starts up at defult multiplier for a split second.

dnar- Tbird 1200's and higher come factory unlocked,so L1 bridges aren't in the picture.

I mean that my JEN didn't have a shorting block at ALL! from the factory. I had to grab an extra from another mobo (VD133 came with a baggie of 5 extras)

[wylie]

I'll have to check that...(missing jumper)
I've been running on upped voltages and having boot problems...
Think I'll try auto once again.
Also has anyone tried bios1005a for this board??

[Dustin]

Mech- I checked the boards. They came with the jumper on, and set to jumperfree (I haven't changed that jumper). Perhaps it was forgotten, or fell off somewhere?

Auto voltage doesn't dynamically change the Vcore. It just reads the stepping mask, and automatically gives you the correct voltage w/o having to change jumpers/dipswitches.


wylie- Been running 1005a since it was a non-beta BIOS. The main difference is the CPU thermal options and warnings.

CPU Fan Check at Power On (Enabled/Disabled) -The board won't boot if the CPU fan is dead.

Fan Check Beeping (Enabled/Disabled) -The board will
constantly beep if the CPU fan dies.

CPU Thermal Option (Throttle/Shutdown) -The board will either throttle the CPU, or shut down the computer if the core reaches a pre determined temperature.

Hope this helps guys. :)

I'll say......this would have saved my Tbird1200
Thanks Dust

It does automatically change the voltage........ Maybe mine's a spedcial version, like an engineering sample or somethin...... I bought it from Mwave

Like its usually at 1.82 and now its 1.85 :) For some reason every voltage setting is a lil off.

1.75=1.82 1.8=1.88 1.85=1.92

I don't know where this 1.85 is comign from, it never was dead on 1.85..............................

wylie - once you get RedHat up and run, I can give you help setting up the lm_sensors package and give you a script i wrote that monitors the CPU temp each minute, then shuts down the system when a preset temp is reached.... If Linux shuts down quick enough, it could save your Tbird..... I don't want to see another one bite the dust mate. :cool:

The voltage readings from your mobo are taken with low resolution A/D convertors and hence slight errors due to "stepped" readings..... You must tweak your software to suit. You can do this in Linux, not sure with what your running.....

[MechCD]

It doesn't really bother me enought to change it :)

seriously, if i set it in the BIOS as 1.75, it reads around 1.8, but auto makes it say 1.85, I think that does something. It can't be that much off just by changing it to auto. Maybe my voltage bridges were factory closed :) (lets hope not)
