My Opteron 146 clock

volts kill as well as temperature, Ted. Putting higher volts through will reduce the lifespan of the chip, not dramatically, but will reduce it. And if you put too many volta through it, it'd just kill the semi conductorness of the silicon.
It all depends on how long you want to keep the chip for

threads like this make me wanna stay single core! decisions decisions!

Nice on STOCK VOLTAGE!!!!!

nah, its actually 1.42. cpu-z is toss!

Id go for thwe higher volts, if it lasts 5 years instead of ten do you really care?

Tend to be my thoughts on the issue too - although having said that if you go overboard you can knacker a cpu in under a year. I'm sticking 1.6v through my venice because at the end of the day, if it kill it it won't be the end of the world, I can just buy something faster.

As for the volts/temp debate, both have been known to kill cpus. EMG is much more of a risk at high voltages.

just got myself one with this spepping
running at 2600 with stock volts with an idle temp of 38 laod temp 49

Just got round to putting mine together and it's running fine at stock (1.46v) at 260*10. Prime stable for 12hrs and counting. Pifast of 38.1 seconds.

Need to work out these zany Bios options so that I can push the fsb and maybe lower the multiplier to 9x.

If that's a SuperPi 1M test I'd expect a little higher. My 146 gets 34 sec @ 2.5GHz with Single channel RAM at 200MHz.

Got one here to have a play with and its also running 3ghz. Prime 95 was stable at 1.52v, but COD2 BSOD'd, so now at 1.536v and its been Priming for 18.5 hours

Good stepping, this one

No, it's the old ***** Pifast challenge. I'll need to find "SuperPi" to try it later once I've given P95 a few more hours

(oops - didn't realise that the "H" place was a bad name ???)

mine got 30 sec@ 2.8ghz duel channel at 200mhz. could get sub 30 with pc4000 memory i think

mj3zero 1.46volts isnt stock, ive upped mine by a couple and its only at 1.42 now.

my pi socres-

1mb 30sec
8mb 5.45sec
32mb 28.16sec

geeza · 7 Mar 2006 at 11:12

Primed yesterday at 2.8ghz 1.42volts for 9hours with no errors

cliffy · 7 Mar 2006 at 11:34

any ideas what theses are like under sub zero heard these steppings can suffer quite badly with the cold bug

Its not volts that kill its the temperature. My 3700 was doing 3.1ghz at 1.55v. It idled at 24degrees and load was 35degrees. I put 45degrees at my load limit.

I reckon your temp sensors are way out,with that clock increase and voltage bump you would have to be using highend watercooling to achieve load temps of 35.Unless you have your pc in a cold room that is, or maybe you live in the arctic regions.

DFI boards are notorious for under reading temps,I would say your readings are a good 10-15 degrees shy of true temps.

yep, motherboard monitor shows some VERY strange readings, like going from -23c to 110c :eek:

somehow i think its lieing to me!

cliffy, yes i think they do have the 'cold bug' not that i have liquid nitrogen at hand anyway

do the 146 use the same HT speed of the 3700+ (1000mhz)?

is max multiplier 10x on both?

On a 3700 the multi is 11. On the 146 it's 10. Both use the HTT bus speed of 200, with the default HTT multiplier of 5.

Currently HTT is the same on all A64 processors. 1000Mhz per core at default.

The HT multiplier is 5x

The Multiplier you are referring to is the CPU multiplier. That is set at 10x on the 146 and 11x on the 3700+.

HT Multiplier and CPU Multiplier are 2 very different things...
