W00t - burning-in 4tw - 3.1Ghz on Water (Opty 146)

Jimbo Mahoney · 5 Jun 2006 at 21:40

After some encouragement from Bundles, I decided to push some more voltage through my Opty 146.

I managed to hit 3.1Ghz with 1.65v, 4M SuperPi stable. (I'm running it @ 1.705v now, just to be sure).

I'd never been able to get the chip beyond 3.07Ghz before, and that was only just 3DMark stable, and I'm running 2GB RAM now too (sometimes the memory controller can crap out before the rest of the CPU).

Got a 27.5 second 1M SuperPi time, now testing for stability in games and BOINC. (It's only a gaming machine, so I don't need 24 hours Prime stable - my important stuff is on a stock-clocked shuttle).

I'd been running the chip @ 3.05Ghz, 1.65v fully loaded (BOINC) for months, so it looks like it's another case of slight improvements in clocks from burning-in.

Sorry, I know it's 'only' an Opty 146 and they are, like, SO last week, but I'm bored waiting for Conroe

Any benchmark screenshots\pics of the rig?

Nice. What method did you use for burning it in?

R B Customs · 5 Jun 2006 at 21:59

good clocks !
BOINC ??

Well done I would also like to know what you have used

Looks like 1.5-1.55 gives the best overclock/voltage tradeoff, if youre worried about putting 1.7 volts through it :eek:

Nice one mate what are the steppings ?

CABYE 0540 FPMW on this 1.4v does 3ghz needed 1.425 for 3.1ghz but RAM fell over

Not done any benching for a while. Old scores are in sig. (3.07 Ghz), so are not gonna be too much different.

Explained in first post. I run a distributed computing task - BOINC. I personally run Einstein@Home, but take your pick from a bunch, including the infamous SETI

Good work fella. Can't remember stepping. Will see if I can fnd it.

EDIT - Can't find stepping, and I'm not taking the WB off to find out

Rig (posted a few times before, and I'm moved house, but it's essentially the same as that).

Got a suicide shot of 3.2ghz here somewhere but i think 3.1ghz was its limit on air.

Sparky · 5 Jun 2006 at 22:30

Got a chance of some GSkill LA off a mate quite cheap Jimbo how far does it go before you need to start playing with dividers?

?

No idea - are you asking about the RAM or the CPU? I'm using G.Skill ZX and I always use dividers on AMD64, often quite 'nasty' ones like 133, 140 and 150. I don't care (too much) about memory. CPU speed > *

Sparky · 5 Jun 2006 at 22:35

Ahh only just noticed you have the ZX doh!.What divider have you set for the RAM?

Sparky · 5 Jun 2006 at 22:36

Dropped mine to 333 and 3.3.3.8 will run quite happy but 3Dmark seems to suffer.

I'm using a 150 divider and 2.5-3-3-8 1T timings.

I think I could get away with 2-2-2-6 1T and a 166 divider on the 1GB BH5 I've got sitting around, but the performance impact in SuperPi, FEAR and 3DMark'01 is practically zero (really - it's like 0.5%), and obviously the 2GB has other advantages.

Sparky · 5 Jun 2006 at 22:47

right time to have a tinker with my BIOS.Thanks for the info and very impressive clock with 2GB RAM mate.

Mikey1280 · 6 Jun 2006 at 11:45

Jimbo what is that strange contraption beneath your rad?

tom_nieto · 6 Jun 2006 at 12:17

W00t, I'm looking forward to my opty 146 even more now. I'm picking it up tomorrow! It's stepping CABYE 0543FPMW and going in an Asus A8N32 SLi. My RAM is going to let me down, but I'm going to give it a run for its money before I sell my current PC and get funds for more, better memory. Apparently the chip does 2.8Ghz with 1.375v (seen it with prime torture test proof), so I'm looking to get it to 3Ghz, although I'm not sure if that's possible on air, it looks like you had to raise the vcore loads just to get the extra 300 Mhz.

Looking forward to it nonetheless, must get new RAM though!

EDIT: CS||nuTs, my memory is PC3200, how much does system performance suffer with slower speeds? Do the dividers affect system performance adversely?

Mine was 3.2 Stable

Hey, there has to be worse people to take advice and encouragement from, surely?

Nice clocks dude, but the way i see it, if your mobbo can give more voltage, then there's more left in the CPU, yeh?

On a side note, if it does 3.1 stable at 1.65v, but you're running 1.7v to be safe, what does it do stable at 1.7v? then when you give it a bit more to be safe, what does it do stable at that voltage?

Hmmm, that's how i ended up running my old Barton setup at 2.3v iirc, lol.

Admit it, you are intregued by the spark side
