Average E6400 SuperPI time?

This new E6400 system took 49 seconds for 1M. Not right, yeah? My Prescot can do 1M in 40 seconds, and I see people on here with sub-20 second times. Everything is installed correctly, all the BIOSes are up to date, what gives?

Everything at stock speeds.
 
Figured it out. My heatsink was incorrectly mounted and the CPU was throttled waaaay back (and idling at 85C). Reseated, scored 26 seconds. Idles at 42C. Much better. :)

Thats what my guess was going to be.

Thats why I buy the 775 to 478 adapter. $5 for a little backplane & 2 pieces to convert your mobo to the same mounts as a socket 478. Which I think are much more secure and most HSF's come with a connector for 478. Plus you can mount it either way (rotates 90 degrees, in case your HSF doesnt)

Now time for you to overclock that badboy!

Edit:
P.S. My time at 3Ghz is 16.938s at 1M places.
 
Hahaha, I wish that box was mine. :( It's a new workstation for where I work, we are figuring out some new C2D boxes and phasing out the Cedar Mill boxes we have been building. So far, I think it's been a success, with the exception of that board not supporting RAID. :mad:

But I actually do have the 478-775 adaptor for my personal computer (the one in my sig), and will be using my faithful SI-120 when the time for Conroe comes, which will be when Unreal 3 comes out (Core 2, 8800GTS, PhysX, etc). I can't wait!
 
18.688s here, running at 3.2GHz. I'd say the average should be around that number.
 
on my 6300 running @ 3.2 I get 17Sec....... (458*7) using a DS3 and G.skill ram

dude, 800*8 = 6400MHz. You are running @ 6.4GHz, what is the stepping code on your chip :eek:
 
Interesting...

Not correctly sinked heatsink could cause performance slowdown.

I am slowly increasing the clock speed on my E6400. Stock is 266 and got it up to 280 lastnight. I'll let that run a week and see before I slowly bring it up to 290.

Nice..I have Kingston DDR2-533, so I doubt I could go that high. I might be capped at 300 because of it. I also would need to replace the stock HSF with something nicer. I'll do that this weekend.

Not necessarily. Most ram will go up one speed grade with looser timings.

So if you have 533, it should do 667 with loose timing. Which means you should be able to hit 333FSB with 1:1 ratio (or 2:1 as Gigabyte likes to call it)

You don't need to run your PC for week. Thats a waste of time. Run Orthos (or dual Prime95) for a 10 minutes if it runs keep going up. Once it fails after just a few minutes, you can either raise your vcore and try again, OR go back down 5 Mhz FSB..... then try to test it for longer, if it fails go lower another few Mhz and REPEAT.

I do the quick & dirty test to find where it can't run.

Thanks, I'll give that a shot. I am out of town that was why I said I'll do it this weekend :)

No, really... I'm at 6.4GHz. ;) I think I should get faster than 20s, don't you?
