X5650 sounding temp alarm .

[david carey]

I had a memory issue with the computer not recognizing all 12 GB of memory so I refitted the Heat sink and fan ( stock ) , same time I swapped the processor for another X5650 I had lying around . I had a few BSODs a day later , but after was working ok . Now I am getting temperature alarms when playing a game that can be played with a very basic computer running to 83C . Anyone have any ideas as to what is going on - is the processor faulty ? My room is warm , but then it is always warm ( a little hotter today ) - currently 32.9 room temp . The CPU is stock .

Why? That's like saying you had a flat tire so you replaced the battery.

And what do you mean by "refitted"? Understand there is NEVER a need to pull the CPU's heatsink and fan unless the cured bond between the heatsink and CPU is broken. But if you do need to pull the HSF (heatsink fan) assembly, you must thoroughly clean the mating surfaces (I use 91-93% isopropyl alcohol) of all old TIM (thermal interface materials) then properly apply a fresh, thin as possible, but with thorough coverage, layer of new TIM. Did you do that?

Did you make sure you used properly ESD precautions?

Did you use new TIM? And, clean off old TIM?
Check that it is seated correctly.
Fan running ok?

same time I swapped the processor for another X5650 I had lying around

If you still have the problem after trying the above recommendations, then, try the X5650 you had in there before.

It is an X58 board with a Xeon X5650 CPU , and it did sort out the memory problem ( it is a quirk of the board ) . First it was seen as 4 gb , then 8gb in task manager , and in other programs . Yes , cleaned , and re- applied paste . Just about to fit into a new case with new CPU ( 212X ) cooler and new (CX650m) PSU .

It was more likely a complete power off (cold restart) than simply pulling the HSF and remounting it as the board would not even see such an action. Only if you removed the CPU from the socket would the board notice anything. But even then, unless the pins or pads were dirty some how, not sure how that would do anything either since all power should be removed when pulling a CPU.

At any rate, I am glad that worked.

Take off the heatsink and put it back on it.

 

[Bill_Bright]

Read the whole thread. He already did that.

 

[Regeneration]

Stock 1st generation coolers use some lame plastic clips. Sometimes it won't seat well and you have to battle with it.

32 what?

With the amount of problems you are having, that board might be toast.

Best solution would to dump it and upgrade fresh.

Might be bad thermalcompound up under the IHS even

Changed the case , upgraded the CPU cooler to a CM 212X and fitted a new Corsair CX650M PSU and temps are nice and low . Back down to seeing 4 GB memory though , will have to re-seat the processor and heat-sink again but I only have cheap paste . Case is looking better , with all routed cables .

That board needs to go in the garbage if this is your fix for memory issues.

32 what?

32c = tee shirt and shorts
32f = Hat coat ,thick jumpers,long trousers and thick socks

 

[david carey]

You get it , I thought 32 was sufficient - at 32F there would be no issue with over heating ( I would be dead though , I have problems below 80F . ) .

That board needs to go in the garbage if this is your fix for memory issues.

It is a Xeon / X58 issue .

 

[dorsetknob]

the pc i am typing this on is running on a MSI X58 with a X5650 cooled by an evo 212 (2 120 fans in push pull)
Ambient temp is 70f (21c)
overclocked to 3.6Ghz Temps across all 6 cores are 22c to 34c
PC has been running since 8am ( 2 1/2 hours).

Could also be bad memory

The last time I had this issue , refitting the Processor and heat-sink fixed it . The only Thermal paste I can get ) already have ) , outside of a 6hr + bus ride , is cheap thermal grease . The computer starts on the third time restarting automatically .

 

[Mussels]

OP is correct, re-seating the CPU can solve issues with missing memory channels on intel platforms. I had a dirty pad on a 4770k cause 3 of the 4 ram slots to not be detected, as an example.

All we can really say here is remount the cooler and repaste it again, and make sure clocks and voltages are correct

 

[david carey]

On the subject of thermal paste , is Cooler Master E2 paste good ? It is about the only one available apart from cheap Chinese paste ( CM paste is 8 times the price of the cheap one ) and is it similar to the one supplied with the CM heat-sink ( which is not identified ) ?

 

[eidairaman1]

Go with it. Typically thermal pastes are within a 1-5 degree delta of each other. It is possible that a thermal sensor failed, or the thermal compound under the ihs of the cpu is bad.

Ambient temps are a big play and case airflow too.

 

[dorsetknob]

mine is pasted with Cooler master E2 ic Essential (gold colour ) so yes its good

 

[david carey]

According to one large comparison test ( not sure if I can post link here ) The CM bundled paste , although to my unqualified opinion looked and felt good , Is not that good . Full 10 degree difference between bundled CM paste and CM E1 ( silver )

Obviously because bundled pastes are for OEM/Value Added.

So get the E1 then.

You can always check out thermalpads toi

 

[Bill_Bright]

Even if 10°C difference, that does not mean the inferior one is bad. Would you be unhappy with a Ferrari because it is "not that good" compared to the Bugatti? Any TIM (thermal interface material) is better than no TIM or even good TIM improperly applied. Just because, 40°C is nice and cool, that does not mean 50°C is too warm. It is in fact, nice and cool too. If you are not doing extreme overclocking, the case interior is clean of heat-trapping dust, and, as eidairaman1 noted, you have set up case cooling properly, even plain old OEM thermal pads will provide sufficient transfer of heat to the OEM cooler.

However, 32.9°C (91.22°F) is quite warm. It is important to remember blowing hot air on a hunk of metal just causes that hunk of metal to heat up faster. A fan cannot cool a hunk of metal cooler than the temperature of the air it is moving.

OP is correct, re-seating the CPU can solve issues with missing memory channels on intel platforms. I had a dirty pad on a 4770k cause 3 of the 4 ram slots to not be detected, as an example.

"A dirty pad" is the key phrase there. Dirty pads don't just happen over time. Your example just illustrates what happens if the cured bond is somehow broken, or the TIM as not applied properly in the first place. It has nothing to do with brand of CPU, or just the fact the TIM is X number of years old. So I stick with my original comment and assuming the TIM is applied properly, there is NEVER any need to pull the CPU and replace the TIM unless the cured bond was broken. It will easily last 10, 12 years or longer. Even if it dries out, the solids left behind are still doing their job of occupying the microscopic pits and valleys in the mating surfaces, preventing insulating air from getting in there.

So how does the bond break? Often, ironically, by the twisting the heat sink to see if it is still tight! But it can also happen by getting knocked about during transport. This is particularly so with tall coolers.

You must have gotten the last quote confused. He wasn’t referencing toward TIM but the actual contacts on the CPU making contact with the socket being dirty which could cause the OP to have to recast the entire CPU

 

[Bill_Bright]

You must have gotten the last quote confused.

No. Sorry. Comment was in response to two points made above. In post #21, David mentioned 10°C difference between two different TIMs. My point is, as long as the higher temp is still good, it does not matter. Lower temps does NOT automatically mean better. For example, there is nothing to suggest a CPU running at 40°C or 30°C will be more stable, perform better, or have a longer lifespan than a CPU running at 50°C. They are designed to run within a rather wide "operating temperature range". As long as it is comfortably within that range, all is good. All the 30°C really gets you is bragging rights.

The point I was making about the dirty pad was in response to post #17. If the TIM pad and cooler were properly applied in the first place, and if the cured bond was never some how broken, there is no reason for the TIM to get dirty. Consequently, memory channels would not somehow mysteriously be restored simply by replacing TIM. The memory channels were restored because the "dirty" TIM was replaced with "clean" TIM. TIM does not just get dirty and it does not go bad just because it gets old.

I note there is not one single TIM maker, CPU maker, GPU maker, cooler maker, computer maker or motherboard maker who claims TIM needs to be replaced just because it is X years old. Yes, it can lose a "few" (typically less than 5) degrees of efficiency over many years. But if a processor "needs" those 5° to keep from crossing the threshold into excessive thermal zones, then something else is wrong that needs to be addressed first - like a failing CPU fan, case cooling or something else. Not the TIM.
