Seems strange to me. If anyone could confirm that this chip can not be overclocked that'd be helpful.
T'is a shame, when I bought it on the web it looked to have so much promise but does very little frown.gif
Any further help much appreciated!

eh..4.5-6 Is the median stable OC for those chips..

Sure..they'll clock higher ..maybe not be stable,though.

Eh? Is that one meant to be a quote with a response?

Also so is it rather extreme that I got it to 4.8 in the first palace? - Also out of interest, how well does a Phenom II 965 overclock? Would it perform better than the 4170?

Still wondering about these NB voltages..... Can't decide what to do with them!

Well the problem continues.

It seems relatively stable at these settings but then does odd things when using Prime95 (If there is a better stress tester please let me know.) It'll either stop processing on one core or (although now rare!) blue screen.

Below are some more detailed settings. If any of you much more clued up people can see the problem please let me know!

417

You are aware of the difference correct? CPU/NB is for IMC inside the CPU while the NB voltage is for the Chipset (usually needed after 240MHz to 260MHz Ref Clock) but it does depend on the mobo, everyone is different. I'll treat this as if it is the actual NB voltage at 1.29v.

your Vcore is 1.536v which does seem high I would have to guess starting with CPU/NB voltage1.325v, and not be surprised if it takes more. Max safe CPU/NB voltage is 1.5v same as CPU.
Lack of CPU/NB can/will give you worker has stopped error.
If 1.29v is actual NB voltage that's fine.
HT looks good
If your stock Dram voltage is 1.5v than 1.6 should be enough but don't rule it out. Try increasing CPU/NB voltage first (I'm not sure what it is currently) and see if it helps. If it doesn't, than give the Dram voltage a little bump and repeat test.

Hi Truckerguy,

I actually didn't know that! Thought the CPUNB was also on the mobo!

In the BIOS I've currently got the CPU/NB set to 1.425,

I have the mobo NB set to 1.2 (this is the one I am somewhat scared to increase! for not knowing what the max voltage is)

Thanks,
James

yes dont bump the NB much more on my board the colar of the number changes as you incress it black is all good yellow and its getting close to the edge red means whoo and you see it if you push the voltage into the red temps shoot up like right now!!!

So your saying that for stability I'm best to raise the CPUNB up to 1.5 also?

Or should I raise it by small bits and see what works?

Thanks,

what mobo do you have?

Gigabyte GA-970A-UD3

Seems pretty good, not the newest but seems pretty good for the price

its a ok board for a 4+1 board so Id keep the cpu/nb bellow 1.42 volts but make sure to watch your board and cpu temps
