SETI performance not right... plese help

[XBoxLPU]

Pentium IV Northwood 1.6A @ 2.32ghz. 145 FSB, 4:5 ratio, 1.600 Vcore. SPD memory timings
128 Crucial PC2100 DDR Memory!!
Asuss P4S333 ( with P4S5333Bios )
10GB WD hardrive
Rage 128 4mb PCI video card
Windows 98SE. Seti Command line. ( Seti driver )

I was running that motherboard and Processor with Windows XP and was getting under 4 hours WU. I moved the motherboad and processor to my mom's PC and now it is taking over a day or so to do even a WU. I am using the Seti Driver with command line. Windows 98SE

Why so bad of performance ?

 

[Assimilator1]

You need to get a Task manager to see what processes are running ,maybe SETIdriver is running SETI twice? ,that can happen sometimes.Otherwise SETI should get about 97-99% of cpu time with nothing else running.

Btw how are you measuring SETI's performance?

Seti Driver

Ran the task mang, and the seti commandline was the only thing using the CPU.

I just Changed her screensaver to none, turn system standby off and changed the hd to never turn off. I am watching the performance now.

I think you just solved the problem yourself

Might want to consider adding at least another 128 to this guy, under XP your're very close to swapping to the page file with nothing but SETI running, and not much better off under 9x. I doubt that's causing your slow times, but it will help the system overall.

Did you do a "re-install" of Windows 98SE? You have to let it install new drivers for the motherboard/processor.

How do the hard drives compare in performance? This would be a factor especially if you are swapping to disk.

128Mb is OK for Win98se(about 64Mb will be spare) ,as long as no games are played or too many apps are opened at once ,I agree though that it could certainly do with more RAM

Btw if you're using SETISpy to check WU time completion know that it isn't accurate until about 50% of the WU is done

The system shouldn't go to standby or turn HDD's off if SETI is running. The screensaver is probably the culprit, I have an old PII (Win98SE) running SETI and having a screensaver on will triple the WU completion times.

 

[XBoxLPU]

128MB is just fine for Windows 98SE

And Yes I did re-install the OS after changing over the motherboad and cpu..

I will report the performance soon.

It has been fixed as now Seti driver saids that the WU will be finished in 3:38 mins..

Now I have two PCs that can complete WUs in less than 4 hours..

 

[Hellburner]

Now you just need to get a proper overclock out of that 1.6A, my guess would be you're limited by the memory, take it off of SPD control and set it to the most conservative settings then push that FSB.

 

[XBoxLPU]

Something is still not right

It just did a WU that took 7 hours... changed the memory settings from 4t,4t,7t,2t to 3t,3t,7t,1t. And Seti driver sill saids that it will take 5 hours to finish and It will probably take longer.

WTF ?

Different ARs will make substantial differences in completion times.

A WU with a Low AR (for instance: 0.01) will take a Win98 OS substanially longer to complete than a High AR (for instance: 4.50).

Of course you would have to suspect the changes you just did to your Mem settings may have had a less than favorable effect on your system. :Q

 

[XBoxLPU]

Thanks

I loaded up Seti Spy and the AR was .023! And I noticed the last 2-3 results have been with some triplets. I must have bad WU .. it should smooth out. I Hope

The AMD machine that I am running has an AR of .452 and no triplets returned. It is averaging less than 3hours and 30mins per WU ..

 

[Assimilator1]

What was the fix to that machine?

You maybe better off with a lower FSB & lower RAM latencies than a high FSB & conservative timings..........at least as far as SETI goes

I made the screensaver none, turned hd to be turned off never, and disabled standby mode.

I am still running at 145 FSB and moderate memor settings. Because the board doesn't lock AGP/PCI, I will keep it at 145FSB. It should do a WU in less than 4 hours..

 

[Hellburner]

A1, I checked out different memory settings and they don't have nearly the impact that they use to. I don't know if it's the long pipeline the P4 uses or what the deal is. It warrants further research but I just haven't done it... The different between 1.5,2,2 and 2.5,3,3 timing was less than 1%, on the old BX chipset with SDRAM you could push 15%...

I seem to remember that you want to use "Blank Screen" for your screensaver instead of "NONE" when using Windows98. If you do not see "Blank Screen" as an option, go to your Control Panel/AddRemove Programs/Window Components (or something like that) and you will find in one of the modules "Additional Screen Savers". Install that.

That will save a little more of your resources.

Just remembered. Click on the Team AnandTech SETI link in my sig area and go to Step 10.

 

[XBoxLPU]

Heh Sorry guys

I am on this team ..

I think my bad performance right now is just that i got some bad WU .. .. and I Just changed the screen saver to a blank screen.
