S@H What WU times should I expect with an XP1600 with PC133?

[Assimilator1]

I see the XP's are getting cheap here (relatively) in the UK ,with the XP1600 costing just £50 at Ebuyer.

I have a Duron 1.2GHz(unlocked with 140MHz FSB) here in an Abit KT7a v1.3 using PC133 CL2 RAM ,atm I get about 4.75-5hrs/WU ,I'm toying with the idea of fitting an XP1600 to it but I don't know if it would really be worth it.What WU times would an XP1600 achieve with PC133 RAM?

TIA

(for detailed rig specs see my rig link)

You can probably expect times in the range of 4:15 to 4:45 hr per WU.

I have a Tbird 1.4 with PC133 RAM that does WU in about 5:15. I also have two XP1600+ each with DDR RAM that average about 3:30 min per WU. If you average those times out, you end up somewhere around 4:30 per WU.

That would equal about a half hour difference per WU in comparison to your current setup! Not too shabby for a small investment!

I have an XP1600+ with 512MB of PC133. I have the FSB at 147 and I get times of about 4:15 very consistently.

Alot depends on the motherboard. I built a cheap 1600+ a couple of weeks ago using the ECS K7SEM, used the floppy linux router code, cas3 memory 256meg but used the onboard shared video and got 5:30 most of the time. Running in XP after I added a hard drive the times came down to high 4's low 5's. But for the price K7sem $58, xp-1600+ $55, 256 meg pc133 $25, powersupply $15, and a floppy $10 You get a cruncher for $163

What you pay for in $'s we pay for in £'s here!

....well almost

Anyway ,so it looks like I'd get about 4hrs 20mins/WU (ish) ,145Mhz is the highest I can set with my RAM etc ,but that is with 4way inter, CL2 & Turbo settings .
Looking back through my SETIQ logs my Duron is actually doing 0.4xx WU's in about 4hrs40-45 mins ,slightly quicker than I remember ,so I dunno if thats really worth upgrading it atm.What I'll probably end up doing is to wait for the faster XP's to come out & the prices to drop for the current crop & then buy a new CPU for my main rig & then put the XP1500 I have in that to the Duron rig

Thanks guys

Btw more WU times would be appriecated

 

[RaySun2Be]

Btw more WU times would be appriecated

No problem. Here is my P166 running NT4.0 SP3:

..RPD..RY..RT...AVG CPU......Last Result
.0.61....1....0..1d 15h26m....1d 2h00m

And here is my AMD K6-2 500mhz:

..RPD..RY..RT...AVG CPU......Last Result
0.76.....1....0..1d 6h25m......1d 1h29m <---boy does this SUCK at SETI. Only 9 hours faster than a P166. :Q


Does that help?

 

[Assimilator1]

*me snatches his cane & whacks him with it!* ,that'll teach ya for being a smart alec ,

I've added to the line.
Btw I had a Pentium 233MMX@266 that was only 1/2hr slower per WU than a K6-2 @ 375 ,both had 75MHz FSB,SDRAM,CAS2!

Btw more WU times would be appriecated for an XP1600 with PC133 RAM

 

[RaySun2Be]

*ouch* :Q

Hey, I was just trying to help. You said:

Btw more WU times would be appriecated

So I did.

What did I do that was so wrong? :Q




/me grabs the cane and *whacks* Assimilator back.....

Here's the WU times for my P4 1.8Ghz/512mbPC2700 Workstation rig that's doing SETI for CADkindaGUY (in exchange for his Tbird cracking ECCp for me )

Name... RPD RY RT Avg CPU Last Result
JoinT'd. 5.92 4 4 3h58m 3h05m

 

[networkman]

Heh.. Assimilator1 and RaySun2Be are both whacked - who'd've guessed?

 

[Engineer]

Click me...look down the pages to the USS XP1600 systems.....although they are running DDR!

Will be adding two more just like USS XP1600 #3 this weekend if everything works out ok!

#2 and #3 have Win2k Pro SP3...#1 has Win98SE (until I get to install Win2k)

NONE are overclocked in any fashion....just love that 3:58 WU time from an XP1600 system!

 

[IJump]

I think a system that is not overclocked is just plain wrong...

 

[EvilWobbles]

Click here to see my Home Fleet

Be sure to check out the XP1600+ that is doing WUs around 3:30.

I'm not sure what the secret sauce is for that rig but it kicks out the WUs like crazy!

 

[Assimilator1]

Thanks guys, though I'm really after WU times from SDR SDRAM rigs

Btw my XP1500 @ 1.58GHz (150 MHz FSB) does 0.417 WU's in 3hrs 20 mins

Man, just running my computers 24/7 increases the temperature in the house by 2-3 degree's celsius & in my room by almost 5~! I dunno if I could deal with any more heat~!

Yes, the clock is too fast... Oh, wasn't it that you was meaning?

Based on my slowest machine, a processor that claims 1600+ should spit out a wu in under 3h43m. Well, in my experience, AMD isn't fulfilling their claim...

As for overclocking, this machine is running at default speed, that insidentially is slower than the bios default speed... but is still the fastest machine based on MHz...

Want to expand on that? ,what RAM is your XP1600 using ?

Btw you can't have the clock rate too fast

 

[Rattledagger]

Hmm, there did I say I've got a XP1600+

Expanding a little on the post, the comparing-machine is the good, old, dual-p2-333 MHz. Now, taking it's average of 17h56m, you get 3h43m if running at 1600 MHz. Since the slow machine is dual, it has also got some smp-penalty in seti@home, so the result will become even worse.

Ok, as for the AMD-claim, it's a Tyan Tiger 2460, MP1600+, one 512 MB Apacer reg-DDR-ECC-266. This is averaging 4h22m.

Is the RAM running @ CAS2? ,can you enable 4way interleave?can you select Turbo or choose 2-2-2 for the RAM timings?
If the answer to all of the above is no then that explains the higher WU times ,also using ECC RAM will slow things a little

Hmm, there did I say I've got a XP1600+
You didnt say about your RAM

I had a xp1800 with 128mb sdram on a biostar m7vkq running @145fsb. It did about 5:00hr in win2000 and 4:40 using redhat 7.3 and wine. When i put it in a soyo dragon+ at 139fsb with 256 ddr it put out 3:38hr wu's. my dual duron 1.2 @1330 with 256mb ddr does wu's in 4:58. Someone a while back put a link up for calculating the best settings for overclocking and it had SETI wu times calculated on it. There is a big difference between sdr and ddr. hope this helps.

[Rattledagger]

For the AMD, there isn't any settings in BIOS, except for ECC, but I think the memory is CAS 2.5
The p2 is running at CAS 3.
Digging back, running only 1 seti-instance, the result was 4h2m.

Taking a look on ReaganCRW numbers, this gives 4h5m based on fast 1800+, and 4h8m based on overclocked duron.

 

[Marrkks]

I have run a couple of weeks on a ecs k7s5a, xp1600@146, 128MB pc133, cas2 ultra. win98. I got about 4:15-4:20 for "avg. wu's".

the exact same setup with 256MB ddr drops the times to about 3:30-3:35.

That's odd ,something isn't right there,that's slower than my Duron @1.26GHz with 140FSB on Win98SE.
Your Soyo board times seem about right though

I know the link you mean for calculating WU times ,it can be found @ the SETIspy site ,thanks for reminding me

SETI timer gives 3hrs29mins for my XP DDR rig which would be about right for Win98,but is a little too high for Win2k
For my friends Duron DDR rig(1.13GHz) it gives 4hrs 48mins which is about 10 mins too high.
It doesn't have an option for Duron Moragn with SDR RAM

SETITimer gives 4hrs 19min for an XP1600 on SDR RAM
I don't think the calculation takes into account RAM @ CAS2 ,adding 5% to RAM speeds to account for CAS2 settings gives 4hrs 16mins for the XP 1600
on SDR,4hrs 46mins for the Duron DDR,3hrs 26mins for my XP DDR which is closer but still slightly off

Rattledagger
For the AMD, there isn't any settings in BIOS
That'll be why then ,pitty ,maybe you can get some uquivalent to softFSB to change it from within windows?
One other point ,dont forget that your PII has 512K L2 cache where's the XP's have 256K (even if it is full speed)

Marrkks
Thanks ,exactly the answer I was hoping for
btw thats the SiS chipset isn't it?

So it looks like I would go from 4hrs 40mins with my Duron @1.31GHz(145FSB) to 4hrs 20 mins with an XP 1600............. doh! I've totally overlooked the fact I would be overclocking it ! ,I reckon it should hit 145 FSB giving 1523MHz ,SETITimer gives 4hrs dead accouting for CAS2 settings ,suddenly that looks a whole lot more tempting!

 

[BofRA]

Here is the link to the program I was talking about. it is based on alistair's calculation's but has more options.


SAHOO
