Pass in Intelburn but failing in Prime95

[Greyform]

trying to push from 3.9 to 4.1 I pass in Intelburn but failing in Prime95 real fast rounding error. Please let me know if there is any information you need to help with suggestions.

Thanks

This was posted in your other thread:

note: When you include Memset in your screen-shots (as in your linked to thread), use the SPD and ">>" tabs to display additional information

**edit**I suggest using the maximum available memory when using IBT.

Re: Pass in Intelburn but failing in Prime95

Usually I don't get involved in the Overclocking posts especially when people are trying to push their systems way too much, which it appears you are doing - but each to their own

It seems that the Quad cores such as the Q9550 won't overclock with the same stability as their Dual Core counterparts (in percentage terms) and hence you'll see most memory manufacturers show their top end specification ram (ie overclocked system) in dual core setups, so expect limitations

If you are a gamer you may find issues with other tests too, such as Gaming/Benchmarking when you are stressing the NorthBridge in more than one way.
I've found that too that using a rolling Demo such as Egosoft's X3 Terran Conflict can indicate overclocking issues that none of the more "specific" test programs did.

Also as Windows Vista uses ASLR, you may find that after each bootup that your stability results are different as some "failing" regions of your ram are not being used.
So you really need to either tweak a few more settings and "fine tune" or back the overclock off if you want some stability.

Re: Pass in Intelburn but failing in Prime95

It is mentioned in so many other threads that vtt should be less than vcore.
I see Conners' settings for 3.91GHz and he didn't even touch vtt or PLL.
Now I know no two systems are the same even if they are bulit of the same parts, but still you may want to have a look and try ways other than just pushing up voltages.
