Normally I do not touch other voltages.
You can if and only if u wan to go extreme 

-pWs-

amd cpu have the limit... pushing more vcore that doesn't even help improve the stability of it means u just hit the wall....
u can drop the clock and prime until u can find the stable clock it can support...
drop vcore slowly and prime to find the best vcore for it....
i already tested a lot 4000+ and they almost dun like to climb to 3ghz stage....

5000+ black edition might be the nice upgrade to gain 3.2ghz with multiplier change to 16x
i just tested 5000+ just now and it can even go to windows with 3.0ghz without adding vcore but no futher test...
3.2ghz can boot with default vcore but blue screen at windows means it want more more vcore 

but if can get like f3 version now.. i mybe think to change to it.. dont like higher vcore..
i think it's more like to stable ur oc when u push ur HTT..correct if worng

add me bro

3800 f3@3091.8ghz | alive88 | TF590SLi | Crucial Ballistix PC6400 | 1030 | 5-4-4-5-11-2T | Stock

probably you have no idea about what is F3 windsor 
alive88's vcore is consider too high adi for him to do 3.0GHz

check this out, what can a F3 windsor do at 1.475v

At last manage to use 5x HT Multi already @ 3200Mhz

Yea...HT Link Multiplier. Different motherboard w different setting.
Check it out. This setting should be existed in every board
Haha...I copy CV6149's setting

Me near J.Jusco, and u?
not lapped till mirror-like lah bro...
Just lapped the edge more with 1000 grid sand paper.

Will upload photos later

(Photos updated).

I lap cause wanna make sure the proc surface is flat, to me I feel that even lap till mirror-like the results not much different.

hheheheheh...

if u can get 2000 grit sand paper pm me ya....

i oso want it....

yeah, i'm sure we are talking about the same m/b ,
HT link frequency = HT multiplier
different name but actually they are the same thing

edited : 1000MHz = 5X , 800MHz= 4X and so on
