Times look about the same as my 3700+SD since they were both running 2.8Ghz. Anything 6/24 has been run on the X2 two WUS at a time. These should be updating throughout the day. All ran on optimized client.

These results look great! Congrats with your new PC! :)
I was wondering if Boinc would use both processors, but you're saying that it now crunches 2 WU's at a time and as if it was 2 AMD 3700+? That's great. Under 1 hour/WU is less than half the time my slightly overclocked AMD 2500+ does.

Is this a do-it-yourself computer? Or an off-the-shelf?

Just curious ...

So, you've got the 2.2Ghz X2 4400+ overclocked to 2.8Ghz? Not bad since it's still looking stable and validating well. I assume you're using something more effective than air cooling?

Its water. I ended up really lucky with this thing. I'll probably be able to get 2.8Ghz stable at 1.475v versus the 1.7v it took on my San Diego. It could be possible to get 2.9 working around 1.55-1.6v and 3Ghz for basic testing (at 1.7v though). I did not take not before I installed the CPU but by going by some of my papers from Monarch this could be a 013 chip which would pretty much be the center cut where they usually pick out the FX chips.

Holy processors batman, that's fast, real fast!

Live long and crunch.

Re: AMD64 X2 4200+ Results

I recently put together a system based on the new AMD64 X2 4200+ Dual Core CPU and an ASUS A8N-SLI Deluxe mobo with 2 GHz of HyperX Dual Channel memory. I am getting about 2.3 hours per two work units on average with no overclocking of the CPU.

Is there anyway to operate the dual core cpu in parallel mode to see how fast it could process one work unit (i.e. any versions of seti@home that can take advantage of true parallel processing?)

Erm...I hate to disappoint you Mark, but my lowly 3.2GHzP4 Prescott does 2 seti wu's in 1.5hrs. I suppose that is with the optimised SETI client though.

Live long and crunch.

(S@H1 8888)
And proud of it!

I have the same 1.5 hours per 2 workunits with a Prescott 2.8GHz (HT/SSE3) and optimised client 8.1... And all HT processors (not only dual core X2) are running 2 units at the time. I have paid 100$ for processor and 24$ for MoBo. Beat that X2 on units/dollar raport :P

Very nice. Here's my results on an X2 4200+ at 2460MHz:

http://setiweb.ssl.berkeley.edu/results.php?hostid=1091915&offset=40

It's actually SETI stable at 2580MHz+ on air. My 24/7 is a conservative 2460MHz. Don't forget that these X2's are running 2 instances at once just like a dualie.

I love my X2!

Nah, it's probably a piece of junk. Send it to me, I'll check her out for you. I promise to return it promptly (a year of so)

LOL

After posting this it did 2 wus and rebooted ;) I spent a while stabilizing my OC and benchmarking. Backed off to 2.75Ghz so I could drop my vcore from 1.625v to 1.525v. Its going strong now. So far in the last 18-20 hours it has done about 40. Two per hour for one PC is not bad.

Has anyone got a X2 with 2MB cache (4400+ or 4800+)?
I expect the higher cache to make a big impact.

I'll need to confirm Tony's results so forward it hear in 11 or 12 months. ;-) -- Skip

I called the post office and told them that Tony has moved and had it redirected to my house LoL

98SE XP2500+ @ 2.1 GHz Boinc v5.8.8

And God said"Let there be light."But then the program crashed because he was trying to access the 'light' property of a NULL universe pointer.

Grrrrrrr

Has anyone got a X2 with 2MB cache (4400+ or 4800+)?
I expect the higher cache to make a big impact.

ewitte2 has a 4400+ which has 1MB per core. He also has better cooling than mine. I run my 4200+ at 2490MHz 24/7 with 1.475v on air. He runs 2750MHz on water with more volts. I've tested three different models and the cache does not make as large of a difference as I expected it to in SETI and other similar applications. It does make a big difference in single threaded apps like games though.

This thing will bench up to about 2.95Ghz but needs 1.7v for that. I've already sent my first paypal payment to someone so they can build me phase change ;) BTW with water its not that hard keeping below 40C, its mainly my PWM (mosfets) that take a beating. I've had to actively cool it to keep it below 53C or so. The thing about phase change is I could possibly pull that same 2.95Ghz off at like 1.475v and be stable. I'm guessing it will top out around 3.2Ghz.

OK. I would've expected a larger cache would make a bigger impact though. Maybe it must be more than 1 MB per processor to really make a difference. I don't know why AMD doesn't use the advantage a larger cache would have in many applications...

Anyway, for those who cares, here's a comparison chart of these AMD X2's.
