Superpi 1m Benchmark Competition

yes i understand your point but still a dual core and quad core doesnt perform the same in spi and i dont want to create a sub category only for the q6600. also if you look at the i7 is 45nm but still isnt comparable to a dual core 45nm, from my point of view.

It might be easier for you to check in on my biggest e-peen thread evar .

That's good ... but realize that there's nothing wrong with suicide runs. That's part of the skill of overclocking...getting the most out of your HW that you can, with the equipment you have.

Oh, but I totally agree 'tank. But I always try to find the highest stable first - then I go for the runs. With BOINC still down, it gives one more reason to push the Quad in unknown territories tonight. And get that Ram upto speed finally.

More at 8.

the i7 is a different architecture. And if you have a 3GHz QX9650 and a 3GHz E8400 running the exact same OS with the same RAM settings and everything, the would be nearly identical as SuperPi is single threaded, so more cores give no advantage. Any more than 2 cores is no advantage to SPi. And again, by architecture I mean all the 65nm and 45nm Core based chips would be together. So what I'm suggestion is the following categories:

Pentium 4 Based: (Pentium 4 and D)

Core Based: (Core 2 Duo, Core 2 Quad, Core 2 Extreme, both 65nm and 45nm's together)

i7: (Nehalem of course)

So it would be something similar to the 32M low clock challenge over at XS: 32m SPi Low Clock Challenge - XtremeSystems Forums

9.734s
Intel e8600@ 4800mhz/Yes on air!
4GB Mushkin Redline 8000/ 480mhz 5-5-5-18 (underclocked)
Asus P5Q-Deluxe
No tweaks at all. Daily OS.WC results coming soon!

Heres one just for giggles



So far thats the best i can get out of this little chip

[3.0charlie]

I've decided to push a bit more.

9.657 secs.
i7 920 @ 4264MHz, 1.45V BIOS
GA-X58-Extreme

Now, check out the Ram speed and timing...

3x 1Gb Gskill PC3-10666 (1333Mhz), running at 1624Mhz, 10-9-9-24 1N...

Hot damn... nice clocks on the memory.

Just a couple of hints for folks who want to play, but haven't been through this kind of thing before.....

Super-pi is very memory sensitive... fine tweaking of secondary memory timings can easily get you 5%+ improvements (big deal when we're talking .XXX between scores... :) ). It's also sensitive to tasks running in the background, so when you get to a point where you think you're not going to get any higher, do a fresh boot, and turn off all of your background tasks before you make the run.

[Finch]

damn now i will have to tweak more . Nice score charlie!

BTW i thank everyone that participates. i didnt suspect it would of been that much popular. I also appreciate the feedback and suggestions.

32m is coming up!

[3oh6]

after a gentle nudge, i have decided to post some numbers. i will stick with just air cooling for now...

ASUS Rampage Formula (0219 - worth .2~.3 from regular BIOS)
E8600 814A526 (killer air/water chip...bad sub zero)
Team Xtreem PC2-6400 C3 @ 500MHz 4-4-4
Thermalright Ultra 120
Stock MB cooling

no real tweaks, just a clean OS and not even memory tweaking. memory has very little to do with 1M...very little, 32M is a completely different story.



i'll try to find some fun 32M air results and post those up later. 1M isn't really my game, i kind of despise it because there isn't a whole lot involved as far as tweaking knowledge goes, aside from a couple tricks here and there. 32M / 01 / AM3 is where the fun is...
