i3 550 - Lots of heat.

post #1 of 6
Thread Starter 
Hey Overclock.net, just recently I started overclocking through the bios, but I can't seem to get something right. Namely the temperatures:

Hardware:
- Intel i3 550
- Cooler Master 212+ Heatsink with AS5
- OCZ 1600 2x2GB RAM DDR3 8-8-8-24
- Asus P7P55D-LX Motherboard
- OCZ 600W PSU

Bios Settings
- Stock CPU Frequency: 3.2 ghz
- Current CPU Frequency: 3.8ghz
- CPU Ratio Settings: 24
- BCLK Frequency: 158
- DRAM Frequency: DDR3-1264Mhz
- QPI Frequency: 6954Mhz
- CPU Voltage: 1.275
- IMC Voltage: 1.30
- DRAM Voltage: 1.66
- CPU PLL Voltage: Auto
- PCH Voltage: Auto
- Load-line calibration: Enabled

- All power saving features: Disabled

Temperatures:
- Idle: 40C
- Load w/ IntelBurnTest: 66C

My goal was to hit either 4.0ghz or 4.2, but with these temperatures, it's making me nervous.

Other people have hit 4.5 on 65C using almost the same heatsink and motherboard, but I don't understand why mine runs so hot. I've tried reseating the heatsink various times as well as followed examples on how to apply the thermal paste (3 thin lines on top of the alluminum). Any advice?

In LinX or burn test you could use 80C as your upper limit for temps, you won't see temps that high in 24/7 usage and Intel's recommended max for 24/7 usage is 72 degrees so you do have some headroom if you don't mind toeing the line.

Don't worry about the temps, unless you know their ambient temperature and your own and you're running exactly the same fan setup in the same case it's hard to compare thermal results.

Also, every chip is different so it also depends on your own CPU.

Your IMC voltage looks higher than it needs to be to me though, your CPU voltage also might be more than enough depending on how good your CPU is.
Mine's pretty terrible in that regard so I'm no judge of CPU voltage for Clarkdales.

See if you can lower your CPU and IMC voltages without losing stability, do them one at a time so you know which one's causing any instability you encounter.

Edit: As for the heatsink and reseating it, I think I used rice grain sized dots on each aluminium line but I'm not sure.
Either way, your method should work just as well and if you've reseated a few times that shouldn't be the problem unless the same thing goes wrong every time.

I'll give it a try and see how it goes, although whenever I know the voltages on anything the test goes unstable or I get BSOD. Speaking of which, I disabled Hyperthreading.

Whatever is below 80C under full load is acceptable. I have it @ 4.33Ghz with 1.28vcore and HT enabled and it stays around 75C under prime95. My heatsink is less capable than yours too.

Ambient temps? And what case and gpu are you using? those can have more to do with heat than anything.

i3 530 4004mhz 1.29v
h55n-usb3
scythe shuriken w/ low speed 92mm fan
gtx 460 twin frozr
SG05

my setup *SHOULD* be running hotter than yours, but I idle at 20c and prime out at around 60c, ambient ~22c

Case: Thermaltake V3 Micro ATX
Video Card: nvidia GTS 450
Ambient Temps: Would explain it since my room is the hottest in the house.

I'll probably run two tests: One of which being with the case door open to see if I'm getting proper airflow. The second being taking it down to the basement and seeing how much of a difference the ambient temperatures make. Plus I should wait a couple weeks for the AS5 to set in because these tests were done right on the hour the heatsink was reseated.
