880GA-UD3H temperature sensors

post #1 of 10
Thread Starter 
I'm currently in the process of overclocking my 1055t processor on a 880GA-UD3H motherboard and have so far achieved 3.9Ghz stable, but have settled at 3.7Ghz as it only requires a minor cpu voltage tweak - to 1.40v.

The temperature readings i've been using have been the TMPIN1 reading from HWmonitor and i've been recording around 49° at load.

I thought i'd give Everest a try and installed it today, but its showing the cpu temp as TMPIN2 - which I thought was the motherboard temperature. The temperatures i've been recording on this are 55° under load - so its not too high, but i'm a bit unsure which is correct.

The temperatures shown on easytune match HWmonitor, but can anyone confirm which is correct?

you are supposed to watch the individual core temps not the other ones.

btw great idle temps

I've currently got cool&quiet enabled, which I guess will be keeping my idle temps down.

I've been watching the core temps, and these have been 43° at 3.7ghz and 49° at 3.9ghz.

I understand the core temps recorded are lower than they actually are, so I'm looking to keep these under 50°, but I'm looking just to confirm which is the correct CPU temp as reference.

edit:
Here are my temperatures at load (3.7ghz with around 10 minutes prime95). I'm a bit confused, as I understood the coretemp is around 10° under the actual temp (as recorded by the socket temp). So i'm not sure if I should be using TMPIN1, TMPIN2 or Core temp + 10 or 12°.

(just for reference I have added a thermalright mosfet cooler so i'm reasonably happy overclocking wont damage the board)

Even heatsinked 4+1 phase can blow up, though this usually happens on MSI boards. I say keep the voltage below 1.45V (below 1.5V if you're feeling lucky but nowhere above that) and you should be okay.
I find that core temps have a 11-13C offset vs. CPU temps.

Your load temps are fine you got more room to maneuver. I wouldnt go above 1.4 since you got a msi board. I never ran my phenom II 940 above 65 and for 247 oc my load temps were mid to upper 40s. Thats more core temps ofc. I have never once really bothered to look at the cpu temps just monitor the cores.

I find that core temps have a 11-13C offset vs. CPU temps.

an 11-13C offset vs cpu temps suggests that everest is reading the correct temperature (42° core and 54° cpu) rather than HWmonitor/easytune 6 (42° core and 49° cpu). I thought this might be the case, but found it stange that a gigabyte utility (easytune) would look at the wrong sensor on a gigabyte board.

For the voltage, I could reach 3.9ghz on 1.45v and did reach 4.0ghz on the same volts but couldnt make it stable - but I didnt tweak any other settings, I just left it at 3.7ghz for the time being.

I've been reading up about 4+1 phase boards (unfortunately after I bought this board) and understand the issues may have occured due to poor manufacturing on MSI boards rather than the phase type. On this gigabyte board it uses an 8 pin connector rather than a 4 pin, which I understand will help give more stability.

Either way, i'm not looking to go over 1.45v at any point in the near future, so it should be ok.

I've bought a new case (Silverstone FT01) and am getting much better cooling, but i'm now convinced that there is something wrong with the temperature sensors

newcasetemps.png

On this, the lowest temperatures are 10° which doesnt seem right.

I think the load temperatures i'm seeing also a bit on the low side - considering i'm running at 3.7ghz, and only using a hyper 212 (original with stock fan).

Any advice on my temperatures - do they look right or are the sensors reading incorrectly?

Yeah, the Gigabyte board is pretty reliable with low RDS, proper mosfet drivers, etc. I still recommend adding mosfet heatsinks for doing moderate or so overclocking, but you shuold be fine for the most part. TMPIN2 is the mosfet temps; they usually load the same as the "CPU temp" value. A recent post about the x6 temperature sensors is telling us that we can trust the core temps.

It makes sense that TMPIN2 is the mosfet cooling, as this has dropped the most from changing the case. I have got an aftermarket mosfet cooler, but now I have a 180mm intake fan right above it, whereas previously I was relying on the cpu cooler to pass air over it.

I'm going to borrow an infra red termometer over the weekend so i'm going to try and verify my temperatures.

Any chance you could link to the post about x6 temperature sensors. I'm finding such conflicting information over the amount of offset etc, so it would be good to have a definitive answer.

edit:found the post.

Interesting information from AMD about 1090T
