So far i'm 10 hours in Prime95 custom test / 90% RAM. *crossing fingers* until I get home from work that it's still stable.

Weird thing though: At the 20 to 30 min, my temp jumped to 91C, but after that test passed. It never broke the 80C mark.

Woa... are you using the stock Intel CPU cooler?
90'c at 1.14 v screams at me that something is wrong. Even on Intel Cooler I don't think it should be that high.

I don't ever break 70'c even when encoding a 2 hour video using all threads.

Can anyone let me know what their stable voltages are at 4.4?

Thanks a bunch!

 

I need 1.13 volt for 4.5 ghz, but my chip is golden. biggrin.gif

 

 

And I'd like to know what cooler you are using, because 90c @ 1.18 volt aint good.

those temps are high. P95 produces the most heat during the 8kk fft, after that its smooth sailing! Sounds like you have got a decent chip there!

I know. I feel very uneasy that it hit 90+ but I have an unusual SFF build using Corsair H60 with an 140mm Akasa Apache fan pushing air in. (case is Silverstone FT03-Mini). Actually, on my first boot, I was getting 35-40 idle and 95C+ on my very first try. Shut it off right away, then I tightened the waterblock after a few days. Then it dropped down to 30-35 idle.

Ah, I see. I was so nervous at that point but was relieved afterwards when it stayed below 80C. (still a little high for my likings) But, before I left work this morning, my hottest core seemed to be steady at 76C for 20 min. I know the Max TDP is 105 and most people say it's okay to hit 85-95 as long as it's not for long periods. I'm hoping my max temps after that heat spike are normalish since it's an SFF build where airflow is not the greatest. But I wonder if I should try and re-seat the waterblock again and/or switch to a better Thermal paste.

I'm thinking it spiked to 90C+ because currently, my case is in sort of a confined space. I will be moving it to a more open area for better ventilation.

Make sure the Pump is working correctly. You have it in correct MB connector.
I have Kuhler 620's on my GPU's and I forgot to plug in the pump. Idle was ok but any load spiked it to 90'c really fast, not a gradual temp climb. Even with no fan on the Rad temps were 30'c cooler!

Oh nice. I was going to get the Kuhler 620 instead, but once I got to the store they sold out and just picked up the H60 2013 edition. I'll have to double check the connection. If I remember correctly, I plugged my PWM 4pin fan to the 4 pin CPUFAN header. But the pump was a 3-pin plugged into the 4pin CHAFAN header. I have an Asus P8Z77-I Deluxe mobo. I'm pretty sure I didn't use the PWM pin. FanXpert reads about 4600rpm for the pump and 1300 rpm for the CPU fan. Any other way of checking for sure?

The dead give away in addition to the sudden temp spike was that most of the heat was stuck in the block and in the tubes coming from the block, the rad fins were cool.
Plugging the pump in using a Mosfet adapter is a sure way of knowing if the pump is on or off, as it is full on when plugged in.

What LLC are you guys using? I turned mine off and had to bump the voltage all the way up to about 1.27 to get stable.

I recommend a lower setting, like 25% or like a Medium setting. The setting depends on your motherboard, so which motherboard are you using?
