i5-2500K/2600K batch number and o/c results

i find pretty annoying the fact that you CANT use the power saving features, which reduce vcore when idling (16x multi) if you set vcore on "fixed mode" (at least on my asrock).Unless you set it on offset mode, you get a straight fixed VID for all multies.. The problem rely in using different VID for different workloads (1c, 2c, etc) and in my case for example, for 4200 1c load requests 1.2710 VID, but 4c/8t requires 1.3461 (at least that is reported in coretemp/realtemp367). If i set for example offset -0.100 LLC3 in uefi i might be stable in heavy workload utilizing 4 cores..(1.199 vcore needed for prime 26.5 ALL threads/core stability) but if have a high single thread load (e.g. spi,prime95-1thread ), the 1.2710-0.1 => 1.1710.. with LLC3 becomes, 1.13-1.15... => "kaboom"... the classic x124 BSOD in very short time.. .I don't know if this can be addressed via a uefi update, or have to trade off , with a bit higher vcore in 4c/8t workloads to compensate for the lower vid in low core/thread-count loads. For the time being, i set it to have a bit higher load vcore (1.208) with different LLC lvl(5) and offset setting, that gives 1.176 vcore in 1core load, which seems stable so far (pain in the ass of course to validate this setting for all 4 cores...). I think the most "simple" solution could be if asrock, for example,(and i suspect all manufacturer's implementation suffers from this offset behavior + fixed vcore not lowering in idle state) could add code that uses fixed vcore in all workloads , and using "request VID" only in idle state, to benefit from stable vcore when overclocked+load and cool and quiet operation when cpu idles.
p.s.> of course someone will point out that "why not using higher vcore? adjusting the offset to meet the minimum required for 1c loads, eventhough you get higher in 4c/8t?" . In my case that means i may use 1.24-1.25 vcore in 8t loads.. which i just find it waste of watts, especially when the cpu has a 100% load.

p.s.2> assuming the fact the the MHz/requestVID slope actually lowers as MHZ increases, the real needed Vcore, may come close to request VID, and posse no problem to use offset mode, but that may be effective in >46x-47x settings, and doesn't apply to mild/conservative overclocks that want to retain cool&quiet operation when idling
