K8N Diamond Plus BIOS problems

Question

Hi , just replaced my lanpartyUT sli-dr expert with K8N Diamond Plus mobo and having problems allready :D
Just finished overclocking and now running at (250 x 11 x 800mhz x 1.300v+0.2v x dram/fsb 1/1 x 2.80v)
Memory timings --> (3,7,14,3,2,8,2,2,1,3,200mhz(15.6us),1,16x,7x,7ns,5ns,0clk,DiCC:enabled,1T,8beats,reduce 00%... ...)
The problem is "BOOT" related... System is PRIME95 stable , but still when trying to "restart windows" or "reset" the system wont BOOT !!?
When i shutdown and then power up, the system boots perfectly !? What can cause this kind of behaviour :/
I have OC:d quite many systems , but this is new even to me

Answer 1

The windows core program shows htt link 1000mhz exact. Memory settings are all "manually" adjusted. Cpu vcore is 1.300 & extra voltage 0.2v=1.5v.
All ECC options are disabled.Hdd:s adjusted manually. Should i rise the (NB) voltage , or does that have anything to do with this !? Maybe not at 250fsb only :D Cool & quiet is disabled naturally :/ All fan controls disabled , connected directly to psu. No D.O.T,s or anything automatic overclocking enabled. The (L cache & data cache scrubs) are strange to me, so those are disabled.After flashed bios , enabled boot sector protection. All the mobo power connectors are in use (24pin+8pin+4pin) Could it be that the memory modules should be used on ports 3 & 4 (now on 1 & 2) ??
