Look Outside | CPU-z (so which is it?) I always thought CPUz was a good program, no?
I have E8400 with Asus P5Q Pro. I think the default is 9x333 so I set the FSB to 400 in the BIOS (nowhere to change the multi). RAM went to 801 from 800MHz.
Core voltage doesn't seem right either. I didn't change that, nor should it have changed from 1.1 something.
Ideas? |

Look Outside | I actually installed cpuz rather than run it from the zip, so it seems to have fixed the issue. Is my voltage ok where it is? How is the RAM looking? |

Likely the first go around cpuz was reporting clock speed while the system was throttled down (EIST, speed step, whatever).
System properties will just take the FSB and multiply by whatever the stock multiplier is. It think my CPU is running at about 4.1 ghz, when in reality it's 3.2. I'm running a lower multiplier than stock.
The RAM has basically the same effective clock speed because you probably have it to auto on the mobo, so it was running a divider before, whereas with the FSB at 400 now, it's at a 1:1 ratio.
Don't see a huge issue with the 8400 voltage, unless it's running hot... |

speedstep/etc lowers cpu multiplier and voltages to save energy and lower temps/fan noise when not needed |

2 edits | Is there a way to turn it off/ do I want to turn it off? I tried turning off the SpeedStep thing in the BIOS and cpuz still shows the clocked down speed. Whenever I run Prime 95 it shows the right results.
I got to 4.05GHz. I see my RAM is running at 901 now (stock is 800). |

Look Outside | Failed Prime95 after 2 hours with 445FSB (4GHz). Should I try upping the voltage or it's not meant to be? |
|

| Not sure why your RAM is at 901 Mhz, based on the clocks above should be 890. That seems like quite the fluctuation.
Anyways, if it's running at that speed, and only getting 1.8 V, that's liable to cause an issue. I'd probably bump it up to 1.9. |

2 edits | RAM is 891 when FSB is 445. RAM is 901 when FSB is set to 450.
I upped the RAM to 1.9V and the vcore to 1.38 and Prime95 still fails between 2 and 8 hours at 445 FSB (4.0 GHz). Computer works though, so what's the deal?
What does Prime95 failing after 8 hours equate to under normal use of the computer (ie. will the computer lock up if I'm using it and not running Prime95 or what?) |

p95 failing means the computer isnt stable. the time it takes to crash is simply how less than stable it is. some people run prime or occt or linpack (1st 2 now incorporate linpack) for 8 hours and call it a day if it passes. |

Look Outside | I clocked it down to 3.87 and I have Prime 95 running for 24 hours and it is passing. |
|
| grats. if you play any games you might want to loop 3dmark 2006 overnight to ensure the system is stable under full load. i know ive gotten CPUs stable but the system crashes when gaming b/c of increased PSU/motherboard load |

Look Outside | Is it possible to do that with the free version? |

Usually means you need to bump the vcore up about one notch. After 10 hours of prime blend, the test just resets... So 10 hours stable in prime should be good.
If you do not already have 25.11, get it... =)

said by fartness:Is it possible to do that with the free version? unfortunately not. OCCT has a gfx card stability test, but i think it relies on CUDA, so only works on nvidia 8600-series cards and newer. also ive never tried it so no clue how effective it is.
OCCT is probably the best all around stability tool. there's 2 methods of testing CPU, the prime 95 25.11+ engine and Intel's Linpack, a power supply load test (extremely heavy), GPU test, and i think one more.

oh i forgot about the Heaven benchmark. i havent tested stability with this (because my OC has been stable for 2 years) but it's the latest and greatest GPU benchmark.

| said by fartness:I have a GTX 260 if it matters. nice. you could run the OCCT GPU test and the Heaven benchmark without problems. If you're running Vista or Windows 7 you can run Direct-X 10 in Heaven and there may be a way to loop it, i'm not sure. you can run the OCCT tests for a time duration so it's great at testing stability. |

Look Outside | I'll give it a shot. I have XP Pro. Thanks. |
|
| with XP you can only run DX 9, so choose that from the heaven benchmark. you need to install Vista or Win7 (preferred) if you want to play supported games in direct-x 10. |

Run Intel BurnTest on maximum stress level. If it runs through 5 passes, I'd consider you OK. Intel Burn Test is even more rigorous than Prime95... If you care about your CPU always giving correct results.
