Not impressed with new Celeron WU times...

[jjmIII]

I just recently built a Celeron 2.0@2.66 on an Asus P4PE mobo w/ 512 of Samsung 2700.

This was built to run a storage unit complex, and is still plenty powerful enough. I was surprised at its WU times however.

Celeron 2.0@266: 6-6.5hours
P3 600@800: around 7hours (Abit BE6 w/ 256mb sdram)

I knew the 128 of L2 cache hurt the Celerons, but I didn't think a P3 would even be in sight.

Still a fun processor. 3.0ghz is easy with some extra Volts.

I have a tualatin celeron 1.1A that runs at 143 fsb (about 1.5ghz) and gets WU times around 5 hours.

What's your fsb running at?

 

[MoFunk]

FSB and ram timings are important to Seti. Make sure your FSB is as high as you can go.

 

[jjmIII]

I'm @133 bus x20. Ram is set DDR333 2-2-2-5 turbo.

 

[Wiz]

well you won't get much improvement without increasing that fsb
Your timings are nice though!
Which version of seti are you using?

 

[Confused]

New Celeron = already bandwidth-and-cache-limited P4 with 128k L2 cache, and lower FSB = Crap!


The only real way to get much better WU times is to ramp up that FSB like nothing! Seti needs fast memory and FSB speeds, and low latency, high bandwidth memory! I'm glad to see it's paired with DDR, at least that helps some over using PC133!

If you are using the GUI, use the CLI. If you're using the CLI, switch to 3.03, which is faster for average and high AR (angle range) WUs than 3.08, and use a SetiQueue that is listed in the thread at the top of the DC forum that has had the "security exploit" that the 3.08 client fixes implemented to the Queue, such as those provided by myself and Smokeball to name a couple.

P4 Celerons suck at SETI cos they need the big cache to work decently as well as a large a memory bandwidth as possible

I had a PIII 933@1.015GHz that would do average WUs in about 6.2hrs!

[edit]
dang Garry beat me to it!
(good to see we agree)

Man, Thats only about an hour faster then my 600 Duron @ 900 MHZ. How dos Intel get away with it

They try to sell people on pure clock speed, and for many that is what counts. But we all know that it is bandwidth that matters most. When I first started overclocking I shot for the highest Mhz I could get. Now I will sacrafice CPU Mhz to achieve Mhz on the FSB! That is where the speed comes from!

Celerons are teh suk.
You have a decent board there... memory might lack a little for very high FSB's unless you run it 1:1. But try getting your hands on a 2.53GHz SL6S2 made in Costa Rica. Then you will see some very good SETI times, or any other project you decide to work on .

In the mean time, try getting your FSB upto 140. My Celeron fails @ anything higher than 138. But from various OC's I see. I have a lame Celeron

Newest CLI...

But try getting your hands on a 2.53GHz SL6S2 made in Costa Rica.

Look at my rigs on my signature. I have a few great crunchers in there. I own storage units, and will remove SETI when I put this rig to work. Its built just as a stable business machine. Which it is.

A cruncher it definatly is not......

:beer:

 

[Wiz]

ok, newest cli is slower than cli 3.03
there is a security risk with 3.03 - but a lot of us have decided it's too remote a possibility for that risk to really cause a problem

On the speed issue, you really do need to get that fsb & memory speed up if you want to do any better with seti (getting repetitve isn't it?)

 

[CraigRT]

Those CPU's are soo slow... that's brutal

my XP1800+ got about the same WU times as my P4 2.4 overclocked..

AMD rocks at SETI..

 

[SinfulWeeper]

Probably from poor equipment in the P4. I can't fathom that an 1800+ is tying a OC'ed P4 unless the 1800+ is OC'ed also
Unless of course the P4's equipment is lacking. Examples: Crappy Via, or SiS chipset motherboards. Poor memory, yadda yadda.

 

[jjmIII]

AMD rocks at SETI..

Ill agree there. My OCd 2100+ is faster than my OCd 2.66 P4. If you look in my rigs you'll see the 2100+ can run 202bus stable, but even an 13(stock) x166(133 is stock) it is faster than the 150bus quad-pumped P4.

He//, I don't really care. All these rigs are fast enough. I started using SETI when I OCd my first home built (400C@450). I figured it was a great test. Over 6600 units later.....it seems I'm still testing.

For some odd reason I love comparing WUs on rigs I build. O' ya.....and the alien thing .


stats

 

[Wiz]

yeah, me too

Can't resist the comparisons... like my AMD 1700+ doing WU's in 2hr 30 mins or less

cpu cost = about $50

What's it cost to do 2 1/2 hour WU's with Intel?

I'vve been an Intel guy all my life - started back with an 8088 running at a blazing 4.77 mhz (yes, that is four - dot - seven seven mhz!)
I won't even talk (much) about the foray with the PC jr. Wow, an 8086 processor running at 2.385 mhz!!!
Now those were the days my friends.
Of course I learned a lot from those machines. If I can remember right the extra ram I installed on my 8088 to bring it from 512K up to 640K ram cost me $13.50 per chip and it took a small handful of them.
Those were pre-inflation dollars too mind you, back then you could get over 2 gallons of gas for a dollar!!!

Yeah, those were the days... Man am I glad they are over forever!!!

 

[SinfulWeeper]

really now?
I would love to pay a dollar for two gallons of gas nowadays .
Bring them back :|:|

 

[Assimilator1]

Pah! ,you guys have got nothing to complain about petrol prices!!:Q ,we pay about £3.42/gallon (76p/ltr) for UL here in the UK

If you ask me you guys get it too cheap! ,doesn't dissuade you lot from having those thirsty V8s

Back to SETI ......

SinfulWeeper
Only the P4 version of the Celeron sucks at SETI ,the Celeron Tualatin does extremely well when the FSB is wound up.
My sons Cel 1.1A @1.38 GHz does WUs in just under 5hrs!.

Mind you the Celeron FCPGA is fairly bad at SETI too cos of the crippled cache ,the older Celeron was much better clock for clock ,performed similarly to the PII/PIII Kat.My old Cel 366@550 did WUs in 10.5hrs
