Cool will give that a shot later on.
Is 74c acceptable or should I just try for 3.2Ghz?

1.36v is a bit high tbh. You could take that down a notch or two.

Sure but lower volts could bring down temps slightly. Or the headroom could be used to get a better oc.
I agree with both of you, but I think less volts should be possible certainly as I am currently on my own system at 167 Bclk for 3500 idle temps 36,32,34,31 and under prime blend goes too 63,60,59,58 v core is set in bios to1.26875 cpuz reads as 1.248 in windows so I think there should be a lot of scope to bring the v core down and reduce temps. I would suggest reduce to something like 1.32 and test then reduce 1 notch and re test etc to find the lowest it will go.
So give it a go at less V core and let us know how you get on.

Awesome stuff.. will try 1.32 tonight 
Thanks for the help ppl

Massive confusion!!!!
The Vcore options state the following -
Auto
Spec
+0.010V
+0.015V
+0.020V
etc..
Now above this it states that the CPU Vcore is set to 1.36v.
I have no idea how to change this as I don't understand the values.
Does anyone with a Biostar know how to do this?
I've stepped down to 3.3ghz to test tonight

Sorry I can't directly help you on this as I am not familiar with the bios of the biostar board - but have you googled for a bios guide or overclocking your particular board?
In your example above though it is saying that you are currently at 1.36v and the values below that are what you would be adding to the 1.36 value if you selected it - so next one up is+ 0.010v which would take you to a value of 1.37V. But I would have thought you should be able to go the other way as well to a - value, which in this instance is what we require.
Sorry I can't be of more help.

No probs.. I'm ggogling now..
Done a quick stress test and was hitting 77c!!
Need to lower the volts!

Just downloaded the manual for your board - and it seems you need to find the" voltage control " section in the bios - in there you should be able to find the Vcore setting and it should allow you to select the value both above and below what you are set at now.
Hope this helps
Mark
Ps also check you are set to Manual overclocking - as menus may be hidden if you are using the automatic setting for overclocking.

Hey mate, the stock vcore is around 1.15 so just calculate from that.
Mine is at +0.140 which ends up at 1.296v.Also check this site out: http://www.rebelshavenforum.com/sis-bin/ultimatebb.cgi?ubb=forum;f=49

My stock atm is 1.296v.
i used the setting off that forum and my Vcore raised to 1.5v lol.. I reset asap!
Got it back on auto atm.. HT on but turbo and speedstep off.
Idle temps are 38, 35, 37, 37.
Gonna give this a stress tonight.. if it passes then it stays.. not risking it tbh

Is that your vcore when not overclocked at all? That seems a bit high...
Running CPU voltage at 1.36v is not uncommon, however, it is only typically needed at over 3.6GHz. Running at 3.4GHz, you should be able to run on ~1.30v, and your temps with Prime should be <70°C.
I would agree that they do indeed seem high for stock although depends on so many things - cooler used, ambient temp etc but more importantly is the heatsink making good contact? maybe time to re seat and apply thermal paste either MX2 or artic silver 5.
I must appologise to Chandler for my innaccurate post last night in trying to help - think my brain was asleep - I will post separately in a mo with correct info.

No probs Mark.. all help is appreciated at this end!
The HSF is tightly pressed against the Spreader.. with plenty, but not too much, of the Noctua Thermal Paste.
Perhaps a purchase of AS5 is required this week.. I just need to find a way of setting the Vcore to a default value of 1.1v or something.. just can't seem to find a way of lowering it.
I'm going to try setting the Vcore from Auto to 0.010v then see how it performs.. I find the fluctuation of the Vcore in CPU-Z disturbing.
Hi Chandler,
Question - do you know what voltage your chip runs at on stock I.e 2.667Ghz on 133 multiplier or put another way everything at stock. When running at stock have a look at the Pc health status page and see what voltage your cpu is at.
Once we know what Vid your chip is running at stock we can then start to increase the base clock from 133 to say 150 save and exit from bios then re start go into bios and check what voltage the chip is now running at still on auto at this point - leave other settings on auto apart from memory which you may have to adjust the speed it is running at so that it is not running more than stock speed or as close to as poss. If you can do this and then check stability in windows with say prime 95 for half an hour and keep an eye on temps.
Try the above and get back to us and we can go from there.

In windows atm @ 3.4Ghz.. runing a Prime 95 blend// temps are 72, 69, 66, 68. Been running approx 2 hours.
I managed to get my head around the Vcore issue by simply only allowing an increase of 0.020v over the default.. thus giving me a constant maximum of 1.264v.
Max temps from this session are 74, 71, 68, 69.
Debating if I should leave this running overnight!
Seems funny that the first 2 cores have exceeded 70c bu the other 2 have not...
