Overclocking phenom II x4 945

So after researching for a couple days, I decided to over clock my 945, after my first round I'm at 234 FSB x15 CPU mult, x9 NB/HT mults, and x5.33 Mem mult. All at stock voltages.
After running prime95 for one hour I'm completely stable Max temp according to HWmonitor is 50C per core, idling at 36C as I type this.

I'm running at 3.51GHz clock speed, 2.106 GHz NB/HT, and 1,247MHz memory, all at stock voltage of 1.34.

But on to my main question, is 50C under load a good temp? Also, should i try running NB/HT at 10x making them 2.34GHz each?

Hmm, that picture is hard to read, also, is it bad that TMPIN0-2 spike to ~84C It happens for a very short period of time, I've actually never seen it happen, I just notice that it records that as a max value. It even did it at stock values for everything.

50C is fine for a load temp. What are you using for cooling?

Xigmatek s1283, I just added a signature that has my rig in it.

50C is not bad considering you're overclocked, but you might try remounting to see if you got a good contact patch on your first install. The HT link running over 2000mhz hasn't netted me any noticeable improvements. The cpu-nb however is the speed your L3 cache runs at which does net you better performance. You may or may not have to give it a voltage bump to get it stable at 2.34ghz. Keep in mind that the increase in voltage to the cpu-nb will increase cpu temp. I try to keep mine at 2.4-2.6ghz

50C is perfectly fine.. you still got atleast 12C of headroom.. once you get to about 60C then you want to start worrying.. but anything under that is fine..

I also have a sensor that does that.. when i boot up and speedfan starts it shows a max temp spike of 121C and a minimum temp of -85C but the sensor works perfectly fine..

btw.. you can upload the picture to phyrefile.com it will leave it at its original size.. ya dont have to deal with the bs resizing crap on photobucket..

I got my Phenom II 945 to 2.525 ghz (235 x 15x multiplier) on the stock cooling, and my temps are 65C at full load prime95 with four threads running large FFTs for over 16 hours stable. I had to bump up my voltage to 1.44v to keep it running smoothly though, 1.8v on my DDR3 as well and +0.1v on the chipset.

I'm quite certain there's more headroom as it boots at 2.6 ghz but heat becomes somewhat prohibitive for longterm use with the stock HSF. I think 71C is the limit for a quad core, so you've got a bit more wiggle room with your aftermarket cooler.

Try using CoreTemp to measure your temperatures, it seems a bit more accurate than some of the other monitoring programs I've used. You only get one temperature, but it seems to average all your cores out.

at least you consistently made the same typo
235x15=3525

Doh, I was half asleep when I typed that.
