post #1 of 13
Thread Starter 
Temps on 0% load from 27-37 degrees C
Temps on 100% load from 50-62 degrees C

Ref Clock : 300 (from 200)
Mult: 13.5 (from 15.5)
Volts: 1.55 (from 1.4)

Memory: 300*5.33 (1600) 7-9-7-24
Volts 1.65 (stock)

Northbridge: 2400mhz (from 2000)
Volts: 1.095 (from 1.1)

Edit: So far stable. I am using the stock heatsink now, I can't wait to push this further with my incoming H60

Too much voltage already. 1.55v is the maximum safe voltage for air.

That's a nice OC though, most athlons don't get even near 4ghz. You should try to drop that 50mhz off the 4050mhz to try an get a lower voltage.

Conner, you need to reply to my PM. I'm really thinking about starting a NC OC Club man and want you to help me out if your interested (since you live in NC too).

Yeah, I know the voltages are a bit high, but I am still messing with it. I just got it stable, will re-do it when my h60 arrives.

Yes, I need to lower my ref clock, I think that is what is causing my voltages to have to be so high.

Problem is I am trying to keep my ram at 1600, The athlon's memory controller cant handle any more than 1600, not even 1666 it wont even post.

That should also let you run lower voltage, these chips usually love water. Your voltage is very good for the chip, it's so high because yours is a C2 :I

Keep us updated when you get it, okay?

Very nice overclock, and you'll love the H60 (well at least i have one, and i love it).

Basically you'll have the same CPU I've got, just with the exception with L3 cache. I'd love to see some benchmarks!

You can try upping the nb to 2600-2700mhz for nice boost in performance.

Yeah, I was thinking of doing 2.6 on the Northbridge, but it runs pretty hot at 2100. If the temp goes up too much, ill just put it back down.
