new X2 won't do >260HTT, old SD did >300MHz!

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?

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

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?
