Core i7 on seti here : http://setiathome.berkeley.edu/top_h...edit&offset=20 the Who? machine! going up, in top 40 right now, I hope to get to top 5 with a single processor.

Memory has always been my weakness so perhaps with some sharp guy like Tony I could get better performance out of this.
I wonder what his telephone number is?:rofl:

They don't mean anything yet, wait a week and then we'll have good info.

Pretty close, I saw app 40,800 as the claim but remember, BOINC NEEDS 5 solid days history with a machine to see that the claims are consistant OR it automatically takes the other machine in the quorum as the norm and you as the outliar.
Now for today, the first "full" day just running WCG I see this for the 1/2 day update..

Statistics
Date.... Total Run Time Points Generated Results Returned
11/3/08 0:005:00:06:49 16,356...................... 28

based on the above being credit granted for essentially 5/8 of a full 24 hour day those numbers extrapolate to a granted credit of 26,170 points per day but remember, the machine is being killed in the quorum so I only expect those numbers to go up.
Even if they don't it is by far the best performing quad that we've ever seen.:up:

There is another little thing about my projected claim. It assumes 24hrs of work. Every time the system completes a unit and grabs another it loses a couple of seconds, so unless the units take longer than 24hrs each to process there's some lost time. More units processed means more lost time but faster subsystems (using SATA2 instead of old IDE HDDs for example, but also memory speed etc) reduce that amount of lost time.
I'm only talking seconds here, maybe one or two between units, but it adds up. Mind you, even if you doubled the total speed of all your subsystems you'd only gain a matter of a few seconds, maybe a minute, worth of actual work time ie stuff all over a day. I think (personal opinion) this is why there's no perceivable difference between single and multi-channel RAM *for this specific purpose*. Even if you could cut that delay down to a couple of milliseconds, you'd only gain a couple of minutes over a whole day.

oh man did i pick the best day to be home sick:D. when i saw those Bionc benches with HT on i literally had a brain meltdown. and from my experience (back in the glory days of P4:D) turning HT on just murders your scores. and bionc does not just use one core when benching. it will peg all cores for a few seconds and then just the first one for another few seconds so HT on will drop your scores a ton but will add PPD and results per day like crazy.

that just sealed the deal for me Dave! Core i7 920 for me and hopefully a 965 and 920 for my buddy at all around the same time:D imagine how much 3 Nelly's all coming on at the same time would boost your scores :eek:

thanks man! fantastic read!

I read somewhere that this is a new implementation if HyperThreading, too. It's not just the same old thing pasted into a new design. This one is supposed to be a lot better.

Seriously, AMD are gonna have to pull the Titanic out of their butt to top this thing!

Yes, it's nice. But in order to be worth it for the main rig, I'd say you need to get at least 4,5Ghz if you are to replace a current >4Ghz Core 2 Quad in order to see a big enough difference. Remember the costs are pretty huge, and will probably be for some time.

Costs, shmosts. I can't afford a regular quad. I might as well not be able to afford a fancy one, too. since I won't be getting either. :ROTF:

My Q6600 might be on for sale soon... it's a pretty good one, even without the phase unit ;)
It does 4Ghz@1,42V on water easily. Interested? :D

Some more info:
First WCG bench at 3733 with HT disabled and I have to clear up a mistake I made.
The first WCG bench I showed with HT enabled was at 4023mhz not 3733 as that is the speed the machine is running at.
Then 2nd a look at what Nelly is doing in her first full day working..

And I can sell D_A my Q6600 B3 lapped that does 3.4 @1.42v

Can I have one with HT disable at the same clock that you had with it ENabled? Plz? Apples to apples and all that. ;)

If either of you guys are willing to sell and ship CPU, cooler, mobo and RAM to Australia for $100 (max I can get my hands on, and I'd have to borrow that) then PM me. Don't worry, I'm not holding my breath. :rofl:

Well, current estimated value of my Q6600 + DFI X38 with waterblocks + 4x1GB Cellshock 1000C4 D9GKX is somewhere in the 400-500€ range I'm afraid :(
Anyway, back to topic, this is not f/s after all (yeah I know I started it :wasntme: )

To sum this up, I get basically nothing each day. I have 2 WUs (HCC of course) sitting finished taking 4:20:25 and 4:18:36. Mind you, this is my main computer so I do plenty of other things on it too, and I dual-boot with Server 03 for some other things. Wow. Just... wow. I want an i7 920!!

are you for real? hahaha 100AUD for all that.. XD

scouring for a good online store in australia that sells goods at a reasonable price -.-. Australia is land of the inflated.

If i was to get a Ci7 setup, i think the mobo and ram would kill my wallet.

i would think if ET was in space, he would also learn how distructive we are, and would avoid our race.

Also they would have good cloaking technology, because they need intergalatic flight, so until they want to say hi, i dont think theres a point in us trying to say hi first. :rofl:

J/K WHO!

It's not a matter of what things are worth. I KNOW that stuff is worth way more than that. My point is, I DON"T HAVE THE MONEY.

... and while you're ragging on our prices, don't forget the exchange rate. One Aussie dollar is worth about sixty US cents right now.

Very nice #'s Dave!

Stock purchase program hits in February and then I'll be looking into a nice present for myself by the name of gainstown... either that or a tankless water heater and a new fence.

Just use cpu's to heat your water, and make a fence out of radiators or something. lol

Btw, as everyone else has said: Nice numbers Dave! :D

You're missing the point. I was talking about the difference between HT on and HT off, just like MM in his original post. He claimed to go from 20.000 to 30.000. That is just impossible.

And I seriously doubt 43.000 a day with a quadcore Nehalem. More like the 20.800 @ 3733Mhz that MM showed in his first post. Please prove me wrong if you can.

That would mean that HT on and HT off would be equally efficient. Which is also very impressive by the way. I was suprised in the first place that HT on (processing 8 threads simultaneously) was actually faster than doing 4 processes at one time. If anything you would expect a drop from turning on HT. But then again, I'm noe xpert on the subject and I would like blauhung to chime in for instance.

I'm getting kinda confused here guys...
I agree with v0dka, according to completion times, it shouldn't generate more than 20-25k/d in WCG depending on clocks. Because finishing times are nice, but nowhere near close to what 30- and 40k systems do. I should know ;) (Dual E5420 @3,2Ghz: Average 34k/d, HCC completion 3:17 for 8 WUs - Dual X5450@4Ghz: Average 42k/d, HCC completion 2:44 for 8 WUs). Seeing as Nelly needs 4:25 for 8 WUs it simply cannot generate more than 25k/d.

Hmm what Vodka is talking about makes sense ,now that i read it again...

Anyone else care to comment on this.Seems quite logical,but i'm no expert(an amateur at best :) ) when it comes to crunching and stats for it.

I mean it can ofc (Dave said sth. about 31k today somewhere around here), but it shouldn't.
Or, the Harpers should get more. I already posted how they get put down by the quota here :shakes:
