This Opetron, will not go as fast in pifast as those Venice cores.

The memory controller on the cpu must be very different on those. This Opty has a mb of cache, rather than 512kb, and its awesme in games, but it will not go as fast as those Venices!

It's at 2.8 at the mo, 2 sticks of ram at 1T and its only just at 48 seconds.

I surrender.....If you weant to crunch Pi....Venice is the watery town to do it ;-)

Sounds like it needs a higher voltage, signal noise can also induce a slower speed, not just data corruption.

no point really....I was just trying to get a good Pifast speed. If it wont beat your Venice ar 2.5 when it's running higher then it's irrelevant,

you and Dak are the Daddies of Pi!

It is relevant. Fluctuations in power will reduce speed, even if the clock is reading higher, it can be performing worse. (also note speeds aren't accurately measured, as there is no way of measuring it.. the speed you see on pre-post and in coolmon or so on is a guestimate from fsbxvoltxjump)

Smooth power is more valuable than high/low.

you've lost me chap.

This cpu is running solid as a rock. THe voltage is stock. It doesnt crash even after 6 hours of hard gaming. Frame rates on IL-2 and Q4 are solid as a rock.

So how can increasing the voltage to the core make Pifast run faster?
The cpu must simply have a better memory controller onboard the die, or the later motherboards are quicker on this benchy.
Pifast loves memory bandwidth. I'm convinced that the cpu IS running at the speeds it says, all the time, with no doubt.

So, presuming that I'm wrong on that, are you guys saying that my CPU is not running at the speed that BIOS reports, because the voltage is too low? Cos I don't think that's true. I set the multi, I set the bus speed, I set the HTT, I set the ram timings, and I see the resulting scores get better as the clockspeed increases.

It just wont do Pifast as fast as a Venice

Just run pifast on my rig, didn't bother shutting absolutely everything down, but still got 48secs.

spot on, considering I've still got the stock speed too.

Why the hell is my x2 4400 so damned slow?

same reason my Opteron is mate....I think it's the larger cache.

Dangy..that's fast mate for a stock Venice

that was the fastest out of four attempts, the others were around mid 50s

Lowest I had was 56.16 or somethin

Trig...forget I ever mentioned it.

no damn it!!!

Muhahaha, my Pifast score is now 49 seconds and theres no tweaking been done
Wonder how low I can get it when I start tweaking the damned thing...
