8 vs 24 threads at Building static raycast accelerator

[QuakeMarine1]

i guess noone can help but lets try

I run an old 8core dual Xeon and can render a scene without problem in 2009 vray SP2 32bit
the same file fail to render on dual xeon12coreHT at "Building static raycast accelerator..."

I notice the same for SP4 x32

so far i whouldnt worry but i am in progress to remove all my old 8cores from farm
how can I get my new nodes to render such a job ? disable HT (it work without) is not an option and using x64 whould output incorrect results (for special curcimstate)
