ernie-c Posted October 28, 2007 Posted October 28, 2007 I've gotten myself a pretested (10x300=3GHZ @ 1.392v) X2 3800+. I managed to get it run OrthosPrime SmallFFT for over 13h with these settings, but PrimeBlend never does. So i played with dividers/ram settings/clocks, no luck. Now i found that anything beyond 260MHz HTT (Multi x3 of course) is totally unstable and would even only boot in 30% of all tries. So i tried to change the RAM, from Extrememory DDR400 CL2.5 to G.Skill DDR400 CL2 with Infineon BE-5s, still absolutely the same. This is strange, cause i had an SD3700+ running on 10x300 and even 9x333 24h+ PrimeBlend-Stable with this Board. The only thing that might explain the situation is that i changed from 2x512 to 2x1gb and the memcontroller is reacting more sensitive. Any clues? Might an DFI Expert do the trick?

ernie-c Posted October 28, 2007 Posted October 28, 2007 here's a list of what i already checked without success: - Different BIOSes (623, 704BTA2, MerlinMod 17.10.07) - Temps (all good: HR05 Chipset Cooling, PWMIC cooling with 120mm Fan) - Swapped RAM / tested even below default specs (Extrememory CL2.5 and GSkill CL2.0) - Higher Voltage on CPU/RAM/Chipset/LDT - HTT Multi (from 3x300 to even 2x300) - Tried different memory dividers Share this post Link to post Share on other sites More sharing options...
Sharp Posted October 28, 2007 Posted October 28, 2007 The only thing that might explain the situation is that i changed from 2x512 to 2x1gb and the memcontroller is reacting more sensitive. On top of that, - Different memory controller will require different settings. What power supply do you have? And what are the temps? (CPU/PWM/Chipset)? And can you post your settings here?
