new bios oc

[PUTALE1]

i have recently updated my bios to the latest 04-06 one with the memory and for some reason, my original overclock wasn't as stable as the 06-23 bios. Anyone else got such problem. ON 06-23, I can oc to 220 with stock timing, except cas 2.5, but with 04-06, when I set that setting, the computer boots but sometimes in windows it gets really sluggish. I now only run at 210. is the ram have problem or it's just the bios trouble?

 

memory is G.Skill 2GBZX DDR400 2-3-2-5

 

I have not test all the timing and such on new bios so I am not sure how far I can push it.
