DPAD and Prescott

[Kokomo]

As most of you D-Padders know I have been running what Intel now calls a P4 E 2.8GHz CPU on a GigaByte GA-8IK1100 mainboard for about a week on DPAD. Don't get too excited about it as it really sucks at DPAD, running only 235 to 250 kmpts/sec. I'll take a P4C or a (gasp!) AMD 2400 any day.

In it's defense, it SCREAMS on SETI, cranking out more WUs than my Dual Xeon 2.4, about 22-24 a day. Guess the 1MB L2 cache really helps out in some ways, none in others, but I'll leave the "tecknicul" discussions to those who know (or purport to know) what they're talking about.

I'm looking for SPEED, and Prescott on DPAD just ain't where it's at. :brokenheart:

Anand has a nice review on it today for those of you who understand such things.

Maybe you could find someone to do a trade with.
Crunch seti for them and they crunch dpad for you.

Ya' know, that's a capital idea! As a n00b, however, I don't know anyone. Any suggestions?

 

[Freewolf]

I don't know what it does in dpad but I could trade you a Barton 2500 24/7 for it. does that sound fair?

 

[Kokomo]

Lemme' see what a 2500 does in kmpts/sec. I think a D-Padder has one and has run Muon1 benchmark on it.

 

[Freewolf]

Ok The 2500 is the fastest machine I have access to right now.It's running on a nf2 MB with dual channel pc3500 right now.

Wow, That is amazing

 

[BlackMountainCow]

Freewolf, is that Barton overclocked to 3200+?

If so, Kokomo, then it will do around 250 kmpts/sec (like mine OCed 2500+)


EDIT: Orange Kid's 2500+ is worth round 200 kmpts/sec

I'm not an overclocker and I'm not sure if you can with this cpu as it's a new oem chip . I thought they was all locked so the fsb would be the only way to do it right?

 

[BlackMountainCow]

Yip, only FSB. I pushed mine on a Shuttle AN35N-U with 256MB of 3200 RAM (TwinMOS/Winbond) right from 166 to 200MHz, upped the Core from 1.65 to 1.7 volts and that's it. Solid as a rock! What mobo and RAM u got Freewolf?

 

[Freewolf]

A7N8X delux ver.1.04 and Geil 3500 ultra

 

[Wiz]

What gets DPAD off? High FSB? Fast timings?
Would something like 220 / 440 fsb ddr at timings of 3-2-2-2.0 on an AMD XP cpu running 2.2ghz do the trick?

 

[Stormgiant]

Dpad loves high FSB.

 

[BlackMountainCow]

@ Freewolf: U got the RAM, u got the board, why not just give it a try?? If u are a bit frightened, just raise the FSB in small steps like 10 MHz and see what happens. The good thing is , that the Asus will return to fail safe if something goes terribly wrong. I mean, making a 3200+ out of a 2500+ for nothing!! Hell yeah!! :beer:

 

[Wiz]

Well I'd trade, I have a XP cpu running 24/7 seti right now that is running 2.2ghz (10 x 220) and it's currently doing a 2 hour / WU seti average. (not bad for an AMD)
If it's a good trade for DPAD and I get a prescott running under my seti account in return then great.

How about the P3-S in DPAD?
I have a 1.26ghz P3 with 512K cache here too so does anyone know how they are in DPAD?

 

[Kokomo]

Freewolf, I agree with BMC. Overclock for a free "upgrade." My personal experience with OCing is limited to futzing about with system bus speeds, but there's a whole herd of folks here who will walk you through it. Some of them have even OCed their microwave ovens to 3.5GHz (stable!), and there's a rumor that one of the "elite members" OCed his Timex to the extent he grew old and died in 2 hours.

As for trading, it's a super idea, but with my P4E already @ 250 kmpts/sec (sometimes), there's no incentive for me to trade straight across the board.

As for DPAD liking the 800FSB, my P4Cs run rings around my P4E. As they both have the 800FSB, what's the deal. Any comments or suggestions? Please confine your comments to words of 3 syllables or less so I can follow along...

 

[Freewolf]

Wouldn't run at 3200 but My cpu doesn't seem to be locked. I was able to change the setting from 11 to 11.5 and it running at 2600 speeds now.

Howdy Yall!
Did I do that "aight" Kokomo?
Thanks Kokomo and DanC for the forum help and I'm glad to be seein that Kokomo is "smartinin up" enough to realize the superior performance of AMD, now if only he could "figger out" that Mopar rules and not those "Found On Road Dead's) then there might actually be hope for him!

 

[Freewolf]

Glad to see you made it Cowboy

Gentlemen, this forum will never be the same again. Someone left the door (corral gate?) open, and look what wandered in --- another AMD puke looking for a home...

Glad to see you finally made the "round-up," Cowboy.

The thanks should all go to DanC, BTW. All I did was my best "screaming, hollering, pounding my head on the floor act," and he went for it --- this time anyway.

Now, gents, let's get some crunchin' going. :beer:

Got my cruncher back on line, BTW...

What he said! :Q

/me goes to wipe the drool from my chin......and my shirt......and my shoes...........and the floor! :Q



That's awsome...simply awsome! :Q

Is that stock speed?

P.S. Glad you made it to the forums Cowboy!

My GOODNESS, a message from on high!

"Obliviously," Mr. Engineer, SIR, you are not the one who over-Ced his Timex, and a good thing, too. I'm glad you're still with us.

Uhhh... What means "stock speed?" I ran it @ 14x222, and had no "bad" WUs. "Worst" was .426.

 

[Overkiller]

hey kokomo,

how hot is the prescott running @ 3.1 ghz and whatsort of cooling do you have on it?

ALso, The prescott fairs worse than the P4C @ same speed much like the WIllimante (P4A) faired worse than the P3 @ same speed. Prescott has a longer pipeline (10 extra stages or something...) which means it will be able to hit 4-5 ghz easily b4 the next revision....BUT a longer pipeline = higher latency..so that is why they worked on the branch prediction and other stuff...

Anandtech actually has a front page article that you might want to check out

hehe....either way...awesome addition man...and "only" 3.1 ghz....COME on!!!! more more more more more!!!!! o/c that pupppy!!! :beer: :beer:

 

[DanC]

Hey! :Q

Welcome aboard Cowboy!

As one who was a die-hard Intel guy... let me assure you that I own ONLY AMD now!
I figure that'll get things "going" a bit over here. It IS nonetheless true.

I made the switch - and never looked back!

Thanks, OverK. One issue @ a time. I have a Thermaltake 7+ on it, and that is woefully insufficient. I'm @ 5500 feet above sea level, and air cooling is not as efficient here as in, say, Atlantis. Best temp OCed to 3.2 is 70C. It will run @ 3.6 for a few minutes @ full processor load, but I shut it down @ 70C. Guy I bought it from said it will do 3.8 with proper cooling. I can see it.

I guess I agree with your comments regarding the Williamette core and it's problems, as well as the pipeline/latency stuff, but don't have the knowledge or experience to comment one way or the other.

If you'll look back to my opening post on this thread you'll see that I made reference to Anand's article. I read it early this morning and --- man, do I feel all smart 'n' stuff.

I have a water cooling kit on order for the now-called P4E, and if I get brave enough to actually try and take this puppy out to extreme speeds, rest assured I will be yelling HELP, my cruncher BSODed again.

Have to mention that when I first posted in the general forum regarding my P4E (which I called a P4P - Prescott), one of the "rocket scientists" there as much as called me a liar, saying, "He doesn't have one." Well, shucks, I guess I do.

Again, thanks for your input.
