Super Pi 1.5 MOD XS 32M Test Fails in Vista !!! [Solution Inside]

[QuadFusion]

Problem:
Overclock stable in Prime95 v25.5 for 12+ hours, but fails Super Pi v1.5 32M Test (even at stock settings) in Windows Vista !!!


Solution:

The windows vista services that affect Super Pi are,

1) Windows Audio Service (this for sure)
2) Themes
3) Aeroglass Interface

By turning these off, I was able to run and complete Super Pi v1.5 32M test.


1) To turn off Windows Audio Service ( start> run> services.msc, find Windows Audio on the list , double click and stop it ) Turning off "Windows Audio Endpoint Builder" is not necessary unless you encounter problem.

2) To turn off Themes ( start> run> services.msc, find Themes on the list , double click and stop it ) this will also make you turn off tune up theme extension.

3) Aeroglass automatically turns off by turning of themes. (you can check it by right clicking on desktop>Personalize>Window Color and Appearance>Color Scheme )



Another way to disable/enable Audio service:

Create two .bat files on the desktop

SoundOff.bat:
net stop "AudioSrv"

and

SoundOn.bat:
net start "AudioSrv"



I found that it is not necessary to run the program as an administrator or Windows XP SP2 Compatibility mode.


I also found a Super PI front-end called Hyper PI
The author claims it is pure Super PI 1.5 MOD XS and it is customized for multi-core CPU's: " Run multiple instances of SPI (one for each processor) and configure the priority of the process easily (without Task Manager). Take a snapshot of all instances at anytime with only one click!"

I personally wasn't able to download it becasue of some server problem.

Here's a Screenshot for the program

Note:
"If you can't get the Hyper Pi program, and want to run multiple instances of Super Pi for your Dual or Quad Core, then run the exe from different folders. For example, if you want four instances of Super Pi to load Quad Core, then make four separate folders, copy the exe into each, and run from each folder. Because if you run the same SuperPI exe to load twice (from the same icon) the initial data is overwritten by the "second running instance." Therefore, what was correct for the first core, or HT in your case, is now being overwritten with the second core's info and it throws out an error "Not convergent in SQR05". There's a little .dat file that's keeping all of the data"

At the risk of being totally underwhelmed by this - what is

Super Pi 1.5 MOD XS 32M Test ???

I personally ran Super Pi to 32 million digits several times in Vista (and overclocked, no less) several times without a crash. I had the services you listed as 'On'. It would seem your case was an isolated incidence. *shrug*

Super-Pi is a program that calculates Pi, up to the thirty-second millionth digit. It is extremely CPU-intensive (Running one instance of it always had one of my cores maxed, and my CPU temperature rose a good 10c. A PC-assembly how-to guide on Corsair says, in their overclocking section, that while many overclockers will use Orthos/Prime95 for several hours to test stability, the author feels that any machine (in his experience) that can run Super-Pi to 32-million digits without crashing is stable 99% of the time.

Interesting sidenote: I didn't run it at stock speeds, but when I ran it with my C2D E6750 2.66GHz overclocked to 3.0GHz, it finished the test in just under 18 minutes. When I overclocked it to 3.41GHz, it finished nearly 3 minutes faster, at about the 15 minute mark. I've never ran Orthos, but my ruig seems pretty rock-solid (I also tested it with a nearly maxed-out multi-hour run on Oblivion and F.E.A.R.).

Na an, I have Vista ultimate 32bit, super pi crashed randomly..

[QuadFusion]

Most Vista users (from different forums) who tried Super Pi 32M had this issue..
The person above (Hunain) is one example from this forum
People at other forums were very thankful because they could finally run the 32M test of Super Pi..
2Cold Scorpio, I don't know how you are able to run .. but do you have Vista home ?
Is it 32bit or 64 bit... I'm not questioning you ? Just curious...

But anyway, my point is that a lot of people with vista are experiencing the freeze up!!!

[QuadFusion]

Another question for "2Cold Scorpio".. are you running Super Pi 1.1 ???

[Hunain]

Yes, I have the problem, thanks QuadFusion for the solution, I really like super Pi, too bad it wudnt run on Vista, I tried a few times and gave up. Thanks

I'm running Windows Vista Ultimate 32-bit, and was completely up to date on updates the day I ran it, and I hadn't done any background service tweaking or anything like that. I was running the only version of Super-Pi I've seen; I just looked and its version 1.1e. The system DID become very sluggish while running it (even with just one core maxed and the other virtually utalized, I had this same issue; Super-Pi really taxes your system!), but it never crashed outright. I ran it three times successfully (and another two times in XP Pro just to compare times). Maybe its just v1.5 that doesn't work? My v1.1e seemed to run fine.

I didn't mean any insult the topic starter; I didn't realize it was such a widespread problem. THough I personally didn't do it, you guys who are having trouble, try turning off your Internet connections, your firewalls and anti-vir software, and anything else you don't need. I was able to keep these things running fine, but the system was so sluggish it didn't matter much (I just put a very long page online up and read it while the test ran).
