At how high a voltage are you comfortable running your .18 micron CPU?

[StarCropper]

I currently have a C-II 533A at 904 MHz with 1.92v. I have a Soyo 6BA+III mobo, CLAP II GTS, 128 MB PC133 SDRAM, MSI Master Slocket, Gorb, Arctic Silver Thermal Compound. Even though 1.92v seems high for .18 micron, I plan on running it at this voltage for the time being. My system is very stable, and after playing Quake for an hour or so my temperature doesn't exceed 36 deg C. I'm curious what voltages others of you are using for normal operation of your oc'd .18 micron cpus. Also, is there any way to estimate the (shortening) of the life of the CPU due to running it at this high of a voltage? My guess is that the CPU still would have a life exceeding 3 years assuming the temperature remains fairly low. Intel indicates that coppermines can run between 1.5 and 1.7 volts. At 1.9 volts I am exceeding their max voltage by 12%.

Thanks for any info.

I Wouldn't recommend going .3 over the default voltage. On the bright side, if it burns out you then have an excuse to upgrade.

I've read in their spec sheet that the ABSOLUTE max is 2.1. I wonder if that's a typo. They were NOT referring to the Katmai chips either.

Anyways, the normal voltage spec for the 1 GHz chip is 1.7 V, but the max listed voltage for is 1.74 V.

With good cooling 1.9 seems fine on mine, but I run 1.8, although I have run 2.0 for testing.

However, I still think you should update your BIOS if you're having problems with setting the voltages. Don't blame me if your EEPROM craps out again.

i have a 6ba+4 soyo m/b
how did you get to 1.9 v
did you do the flash trick
like i don on the old bx6 board
sloket set to 1.7 + 10 %=? 1.84 v i think

Something kind of interesting...

I was playing around with higher voltage on my BF6. Normally, it won't let me go above 1.75V on my CII. I set the Slocket to 1.8V, & lo and behold a 1.8V option showed up in the SoftMenu. Set the slocket back to default, & the 1.8 option was gone. Sounds a lot easier to me than flashing your BIOS to get a higher voltage...

Just a thought.

yes i will give it a try
alough i think the voltage limet is set buy the cpu to 1.7 but i dont no
i will try 1.8 on slocket and see

Viper GTS,

You are right, the same thing happened to me with the BE6-II (which is almost the same with BF6) and my MSI 6905 Master slotket.I set the voltage at 1.8V from the slotket and I get a shift to available voltage options in BIOS up to 2.0 Volts.

That's what I have been trying to tell people all along about raising the voltage on the slotket and then seeing the available voltage in the bios increase. What I do not know, is if this trick works with Abit and Iwill slotkets. It should. I'm comfortable running at up to 1.85v, provided the temp stays reasonable, not over 40c when hardcore gaming for extended periods.

 

[StarCropper]

Well, I dropped back down to 880 MHz at 1.81 V. Everything seemed fine at 904 1.92V, but I figure the performance benefit is negligible in all the games I play, so there is no point in stressing out the CPU.

tielli:

I get 1.81 V on my Soyo 6BA+III by setting the MSI Master slocket jumpers to 1.65 then setting the bios to +10%. For 1.9 V, I set the slocket jumper to 1.9 V, and keep the bios set to normal.

1.79 volts 533 @ 936 gorb cooling. I'm tempted to to go higher,runs at 960 for about 5 minutes then locks. Boots halfway into windows @1008 1.81volts.

I think it might do a gig with close to 1.9volts just don't think I would like leaving it at that voltage.
I have an Alpha on the way then I'll try more voltage then.

Wiz,

Bumping the voltage on the Abit Slocket!!! also works for getting the higher voltage range in the bios. I've tried with my cel 566@ 850 on my BE6-II with Abit Slocket!!!

Wiz, this trick works with the Iwill II slocket and the Abit boards. I set mine at 1.8, and then I have 1.8 as default on my board. Only way, 'cause the be6r2's don't allow the voltage flash trick that the earlier abits allowed.
