Here´s the deal: I´ve managed to overclock 1090T quite nicely up to 4,13Ghz ( 1,49Vcore, bus speed 206, multiplier 20) but thats all I´ve done really and i´m getting a bit suspicious can it really be this easy, meaning every other options in the bios I left untouched ( =auto). At first I was just curious how it would work but when reaching 4Ghz I was amazed.

I´ve allready done almost 6 hour of Prime95 testing (blend) with no problems also a lot of gaming mostly BFBC2 online with no system crashes. So can it really be this simple? Is there something I dont see here? My other components are:

mobo: Asus m4a87td evo/ usb3
ram: kingston hyperX 1600Mhz (4x2Gb)
cooler: coolermaster v6 gt
case: coolermaster haf x
gpu: palit gtx 580
psu: be quiet 750w dark power pro

3dmark vantage score and temps while doing it:

nice, you got a good chip and a nice set up, yes its that easy to OC,
what thermal pasted did you use and whats the ambent room temp?
 
Thermal paste came along with the cooler v6 gt and while running 3dmarks and prime95 I situated the case near open window to get cooler air for the system. Temperature outside have been around 15-17C so it has been pretty cold day here. The room is only slightly warmer at the moment.

Whilst gaming and prime95 testing cpu temps are a bit higher reaching 50-52C (cores) and 58-59C for the cpu sensor.

Use Asus PC Probe for most realistic temps for your CPU mate.

4.1Ghz is awesome at them temps you've mentioned! - You've got upto 62Degrees C (Maximum) before it'll start throttling or bombing out.

I would however recommend pushing up the CPU-NB especially if you are running 1600Mhz RAM. You will be bottlenecking the memory if you don't push the CPU-NB to 2600Mhz ;)

I could run 4.1Ghz but wasn't comfortable running more than 1.45v to it - To get to 4.1 I had to go upto 1.49v - which was too high a jump for a 100Mhz gain. Just for reference I'm running 4Ghz (1.42v) with 2800Mhz on CPU-NB (1.27v) with memory 1600Mhz 8-9-8-24/1T for optimal performance without pushing the CPU too much (Getting 58Degrees C under water)

I'd highly recommend leavnig a couple of Degrees C free for when the weather gets warmer too mate, HTH
 
yeah u need to monitor to cpu temp, not core.

58-59C is really close to the safety temp, also when the hotter weather comes it'll push it over the safety temp

I will try Asus PC Probe thanks for the tip.

Monitoring the cpu temps for 1090T over the OC process has been really difficult mainly because theres so many people saying different things about the matter. After reading (way too) many forums and threads about the matter I believe the core temps are the ones I should be looking at, not the CPU- sensor readings. Actually after finally finding this I was quite sure about it:

(search engine: Interesting Information From AMD about 1090T )

Clarifies the matter quite a bit, and makes sense too. Would link the thread directly here but not sure am I allowed to do so.
 
The Auto core voltage looks a bit high at 1.488V, but if temperatures are under control, it's not so bad. Personally, I wouldn't go 24/7 with it, but I have no evidence to suggest that it'l go wrong if you do.

Dear Gareth,

Correct, as long as you are within the voltage and temperature guidelines you are ok. The temperature that should be monitored is the overall CPU temperature, not the core temp.

Best regards,

but it's up to u which u monitor...

this whole temp thing just goes round and round.

Gareths right, that email your talking about was just a one off and added to a ton of confusion

If its that thread you mean then as you read on there are a ton of different answers all coming with confusing responses, and the email that Gareth has shown is usually the answer you get. I just dont buy the core temp gets more accurate around 45 degree mark as when following the temperture arcs in AIDA etc they both follow the same arc shape, thus something starting off under ambient how can that be right if your using air cooling?

My bad, meant in the starting post that I´ve set the Vcore manually from bios to 1.49. For some reason CPU-Z shows some variation there from 1.404 all the way up to 1.625.

Do you still have turbocore enabled as that will push up the vCore also. LLC would also account for a little but not that much.

Actually at first I forgot to disable the turbocore from bios but today its disabled for sure. Right now CPU-Z is showing steady 1.500 V, somethimes reaching 1.515 but thats all.
 
It does seem odd to me, the core temperature should be more important as the difference between the die temp and the motherboard sensor could be affected by the type of cooler you are using and the location of the motherboard sensor etc. At the same time it doesn't make sense that your core sensors are reading lower maximums than the motherboard sensor as it is the cores which generate the heat so their temperature has to be higher in reality.

The thing is a don't think any of the sensors are an accurate reflection of the core temperature. Going from intel systems the die temperature is generally 10-15 degrees more than the motherboard sensor temp.

Yes this is the one I was talking about.

I´m not saying this is the absolute truth but for the moment I´m leaning towards this explanation provided in that thread. But of course it wouldnt be unwise to keep an eye on the cpu sensor levels also. And if my computer explodes theres only me to blame.
