e6600 running hot...

[spiderhole]

Just put together my new system with following specs...

P5B dlx
E6600 (SL9S8, batch L627A906, 08/30/06)
Antec Trio 550 psu

What I'm finding is even with very conservative overclocking the temps seems really high. I started off with the Big Typhoon + AS5 and then switched over to Intel stock cooling just to compare. Both resulted in around same temps (~1-2 degrees). When I removed the BT, the thermal grease seemed to be perfectly spread (used recommended grain of rice method). Intel HS is now using stock thermal material.

Here are some results...

FSB @ 300 (2.7005 cpu), mem mult 2 (600), Vcore set to AUTO

Temps (Idle/Prime95 Load)

38/57c Asus PC Probe

45/63c CoreTemp

mb 35c


Stock Speeds (266/2.4ghz)

31/52c PC Probe

36/57c CoreTemp

mb 34c

After a couple of hours of heavy Prime95 testing at both speeds I didn't get any errors..but the temps just seem to hot to be safe. All of these readings are with my case cover off. They go up about 5 degrees with it closed. Am I crazy or do these seem really hot for such moderate overclocking? I'm tempted to try another aftermarket cooler, but after such poor results with the Big Typhoon I'm skeptical. Any ideas or suggestions appreciated.

Thanks,
Mitch

There really is no way to know if your mobo is reporting temps correctly (That I know of).
But, if those temps are correct, they don't seem too bad at all. You may want to check the integrated heat spreader on your CPU to see if it isn't concave or convex, limiting the good contact area with the heatsink.

 

[gobucks]

wow those are pretty high. what kind of cooling are you using? I'm using a scythe infinity on an e6400 and I'm not hitting 60C in coretemp even at 3.26GHz. I wonder if maybe your temperature diode is off. I'm using a gigabyte DS3, so I can't vouch for the temp readings on the Asus boards.

I have an E6600 too. its on an Asus P5B deluxe wifi and im using stock HSF and have not overclocked it. Asus probe says my cpu idles at 53-55c :[ heres a screen shot. Oh, my ram is running unusally hot too, about 50c. asus prove screenshot

Keep in mind that with my case cover on they read more like this

@2.7ghz

43/62 PC Probe
50/68 Coretemp

@ 2.4ghz stock

36/57 Pc Probe
41/62 Coretemp

Thanks,

The single biggest thing that people forget is that when you do a Orthos/Prime test on the CPU it does things on the CPU that you'll never see in real world usage. No amount of gaming and video work would tax the CPU so continuously to produce such hot numbers. If it doesn't error on Prime then you're fine.

In short: you will never see those temps in general use.

I'd say it's reporting incorrect temps. You're not doing anything stressful on the CPU as far as I can tell.

is there any way to test if my heatsink is fitted correctly? i had trouble installing it, perhaps it is not fitted properly.

Not really, take it off and look at how the TIM is spread out. If it doesn't look to be spread properly then its probably not on correctly.

Well, I quite often do heavy 3d rendering that taxes both cpus to 100% for sometimes many days on end.

But it's an on/off process. It's like it gets a call, does work then waits for more work so the temp isn't going to go up like Prime. Prime streams numbers through the CPU at a continuous rate with SmallFFT. It really keeps the CPU fed at all times with information to process.

 

[spiderhole]

Well, it is sort of continuous...depending on how long a frame takes to render. Sometimes they can be like an hour each frame, during which both cpus are constantly at 100%. Average would be around 5-15 minutes per frame with about 3-10 sec of "loading, etc" between each.

Ok, been running some more tests with P95 at higher speeds.

Went up to 320fsb (2.88ghz) then tried 333fsb (3ghz) and noticed my temps remained at about the same level at idle and load as 300fsb (+- 1 degree). However, at 333 P95 would give me the following error on both instances after a few minutes..

"FATAL ERROR: Rounding was 0.5, expected less than 0.4"

I have my Vcore locked to 1.325v right now. Should I try bumping up to 1.35 and give it another go at 333fsb? Also, what is the best method to have P95 set to test....Small FFT?

Thanks,
Mitch

SmallFFT tests the CPU alone and that's the best way to test for CPU stability. The blend test adds memory to the mix. It's better to verify the CPU as stable first then test memory seperately.

You probably need more voltage to run at that speed because you got an error.

I had a bit of trouble on the HSF for my Celeron D CPU. Anyway here's how to check that its installed properly.

See there are four "feet" that mounts to the motherboard?? You press those "feet" to mount the HSF. Look at the side of the "feet"(sorry don't know what to call it). You can notice when its installed properly the black part of the "feet" clicks onto the notch on the white part.

Also to make sure, install the opposing sides first to maintain stability when installing the HSF.

 

[spiderhole]

I have a Freezer 7 Pro on the way and will see if that helps (assuming the Big Typhoon wasn't tightened down enough or something). If I still cant get the temps down to something reasonable I might try lapping the IHS and heatsink. Will check to see if my IHS is concave when I do the cooler swap.

I am trying to oc my E6400 with P5B Dlx (OCZ2G800GK + Corsair Nautilus water cooling) ...

Vcore cannot set below 1.525v, otherwise, system will reboot.
With Vcore=1.525v + dual prime ... system reboot again.

Temp (CPU/System):
Idle: 42*C / 30*C
Dual Prime: 62*C / 32*C

Bios settings (0706)
Vcore: 1.525v
CPU Freq: 401
DRAM Freq: DDR2-802
Ratio: 8
Mem Volt: 1.9v

Intel SpeedStep: Disabled

Everything else: Default.

Any suggestion to lower the vcore and temp?
