He's not a gamer or heavy multitasker anyway. I know the next build I do for someone though, I'll persuade them to fork out a few more dollars for a Phenom II. Means no headache involved in overclocking. But I figured since my Athlon II X2 240 in my other comp does 3.8GHz with ease, then these quads would, or at least better. That's a no go. L3 cache won't unlock, either. These chips are just handicapped Phenom II chips anyway, correct? Just Phenom II's with disabled cache and cores? Yeah, defected chips from the start.
Actually I think the last of the "handicapped" Phenom IIs were discontinued before the 640s came out as a way of preventing too many people doing that. I think they are entirely pure blood Propus chips now which mean they never had an L3 to begin with.
But part of me does think that AMD might have pulled an Intel with these considering what I've been reading about the performance compared to the Phenom IIs. I saw many reviews show that when a Phenom was brought down to the same clocks it would beat the Athlons all the time but when the Athlons were clocked up they were within a 2-1% loss and on quite a few occasions even. So making these chips cheaper and risking the loss of Phenom sales I think they rightfully (from a business viewpoint) might have gone with cutting inter-chip competition by reducing the OCing potential. Of course I can't rule out that this might be a mobo or RAM problem instead but it makes sense.
Tried about four different settings and 3.75 was not working. I went up to 1.525 or so on the core and 1.2325 or so on the VDDNB(one more + and it's yellow) while trying out 2.5 and 2.25 GHz for the NB all to no avail. The system did seem strangely better at these settings than when I had the VDDNB up at 1.38 but this might be due to the (hopefully) correct LLC setting I've been using this time around. If I can't get 3.6GHz stable at 1.5 upto 1.525 then I may start considering trying other tweaking goals. First I might see how low I can go voltage wise for stocks. Second I might drop the cpu mult and look for the highest ref clock I can get while being at or above the stock 3GHz speed. Finally, I might sell the Athlon and snag (if it's still available) the 955BE floating around in the market place.
@Cook: You have 4GBs of RAM right? When you boot up and it displays the RAM amount to you get two different results between the ok and installed numbers? IE: I get a result that states "4095MB OK (4096MB installed)".
I want to rule out RAM being bad but I have no clue how. The last time I got bad RAM the stick wouldn't let the system boot so I knew then.
In all for a ~400 total build the stock results still beat the crap out of every game I play except Crysis. DMC4, UT3, Assasins Creed, Dead Space, all maxed out at 1920x1080 and maybe the occasional slowed. Considering that I couldn't truly max any out with my laptop or the last desktop I owned I'd say I got what I paid for.
But still, I'm part of OCN and we're never happy leaving well enough alone are we?
Be back either today or tomorrow with the 3.6GHz attempts. Wish me luck.
