It was bsod'ing at firstname.lastname@example.org instantly in p95 and after 20 minutes p95 at 1.5vcore. Probably going to have to run 1.55vcore to get an overclock around 4.7ghz.
Turbo LLC setting, disabled power settings, ram is just set to 1333mhz (although at 'performance', which is the stock setting, instead of 'normal' - i think that's fine i mean the xmp ram is 2000 cl7 1.65 and i tested it p95 13 hours at 2133 cl7 1.65v).
Maybe I have to play with lowering PLL or the vrm or something or some irrelevant setting, maybe the chip just isn't cut out to do much ;/
That is a very voltage hungry chip. Ud5h should be similar to the ud3h I'm using, I didn't think changing the PLL or power limits made any difference to temps or stability for me up to 5ghz, hopefully makes some difference for you...
thanks for the reply.
Yea looking around more, talking to someone, it seems like something is wrong. 1.4, 1.5vcore, that's like reserved for 5ghz and stuff.
Maybe this chip is like the results out there that are like email@example.com and that being the max overclock and those people aren't posting/doing firstname.lastname@example.org, they just submit/stick to their email@example.com.
But im okay with 1.5, 1.55v, as long as temps are fine, you know. I dont mind a little degradation and all. Anyways I dont even know where to begin with those other settings, I played with irrelevant settings on my phenom x4 build (with no success or difference i suppose but i understand what they did at least, once or twice they made a difference, ie ht link speed being lowered to unlock an athlon x4, having to use mobo socket over voltage instead of vid for voltage to chip during overclocking) a lot...
someone is telling me to change my vdroop setting, based on the following quote:
With it disabled, the steady-state voltages look better, but transient spikes will be worse (and AFAIK there is no way for software to detect the transients). If the CPU suddenly transitions from idle to load, there will be a brief moment when it is significantly undervolted
maybe i change vdroop from turbo, as recommended on ud3h/ud5h for ambient overclocks, to like high or medium.
