So, I got my C0 up to 3.8 Ghz with HT off. Vcore is around 1.35, QPI around 1.4. 200x19.
It seems that it gets unstable, quite so, with the 20x multi at 3.8 Ghz or above. 200x20 is a no go, even with higher vcore and slightly higher QPI. 190x20 is very unstable at same settings where 200x19 is fine.
I have a lapped TRUE black, push pull. Linpack stays below 60 C as of now on a nice cool night. I think I don't have a very good chip, seems to be rather fussy with voltages. So, I am wondering, would it be worth it to upgrade to a D0 if I can expect MB 4.2-4.6Ghz? Right now its not my cooing holding me back.
I have the UD5 from gigabyte. I read some of the x58 extreme guides from gigabyte that recommended some extreme voltages for C0's over 4 Ghz, like 1.6 QPI and over 1.4-1.5 Vcore. How safe is this? Seems rather out of spec.
I have heard that D0's can be better at much lower volts.
So, If I can get a D0 for $200, and *possibly* sell the C0 later, or not, would it be worth it for 400-800 Mhz? Also, our my guesses for the D0 way off, or realistic?
I am also thinking of flashing to one of the F8 beta bios's, here they help alot from F7, especially with D0's.
So...Stay as is? Oc the C0 more? Or get a D0?
Suggestions/advice appreciated.
