3.4GHz LGA775 Overheating & Underclocking Issues

[teh RedUnit]

First off, here are my PC specs:

Intel P4 550 3.4GHz
Asus P5GDC-Deluxe Mobo
Asus EAX600TX/TD Video Card
1x 120mm intake fan, 1x 120mm exhaust fan
WD 36GB Raptor SATA Boot Drive
WD 250GB SATA Storage Drive
Coolmax CR-450B 450W PSU
Zalman CNPS7000B-Cu HSF w/ LGA775 adapter clip

Okay, I just upgraded my PC from a 2.4C P4 which I had running at a cool 29 degrees idle with the same HSF and case fans. I decided to buy the LGA775 adapter clip for my Zalman HSF because the HSF did a great job at cooling my old Northwood.

On this 550 CPU, my idle temps are around 55 degrees and have gone as high as 79 degrees while installing Photoshop and other applications. My mobo temperatures however, stay at around 33 degrees. I used Artic Silver 5 and got those temperatures. I also have the Zalman HSF running at full blast (2500 RPM), PSU at full blast, both case fans running at ~1600 RPM. Both BIOS and Asus PC Probe give pretty much the same temps, so I'm guessing they are accurate.

Also, my CPU is running at only 2.8GHz (200MHz x 14) and I don't know why. I can't immagine the temps if it was running at a full 3.4GHz. Is this the Mobo underclocking the CPU because of high temps?

Here's what I've done so far:
I removed the HSF and re-applied the AS5 but still kept temps high. I've been reading other people's problems but I haven't found anyone with the same mobo and cpu combo as I do. I am tempted to remove the Zalman HSF and use the stock HSF, which I am doubting will do a better job. I've also ran the comp with and without the side panel but still get the same results.

I've already read Intel's temperature recommendations for the Prescott, and while at idle, it's somewhat whitin range, 79 degrees at load is way too high and I am concerned. The underclocking is still a mystery to me and I don't want to try and raise it because of fear of higher temps.

Any help would be greatly appreciated. Thanks

Throttling like this seems to be a somewhat common issue with Prescott chips higher than the 3.2GHz.

Are you sure that the vCore is set right? It could have defaulted to a higher-than-normal vCore for some reason, which would cause it to put out a lot more heat. (this sounds like way too much for even a prescott at 3.4)

Common issue with the prescHOTt. You will have to use a monster and espensive hestsink with good fans to keep it "cool" (near the 60º degrees)

The 500 series were hot and the 600 series has lower wattage and thus run cooler....

I would sya that hsf should have been more then ample....


Is this in a close case right now?? Open it up and get some air in there and see if temps go down...

Touch HSF...It should feel frekkin hot at 79c...If not the temp ios bullshit or the hsf is not making good connection....

AS application needs to very thin...take one drop about the size of a BB and then press the heatsink onto it and slwly twist it left and right then screw that baby down...the pressure will spread it for you.....I dont know if thisi s it vause you must have applied AS rightin the past to get the nice temps on the 2.4c...

I suspect the adapter clip may not be working correctly and this is not making good connection....


Also to see if temps are BS...download an app called Throttlewatch and run it while those temps get over 60c and see if the pcu throttles...if it does then temps are real and you should be worried.

You're an idiot.

I will admit, Prescotts run very hot. But not hot enough for a 2.8ghz + Zalman CNPS7000B-Cu to be load'ing at 79C. Something is terribly wrong, MAKE SURE that you placed the heatsink correctly. If you have a 550J, then it will downclock itself to keep cool.

Thanks for all the advice so far. I already removed the HSF for the second time and made sure it was making good contact. I applied AS5 again and now it idles between 44-47. I seemed to have put a little too much AS5 the previous time, but I'd still like to get those idle temps lower. I haven't tried to load the cpu to see how hot it gets now, but I'm thinking it will only go down a few degrees as well.

I haven't changed any voltages. According to both BIOS and PC Probe, the V-Core stays around 1.384 and 1.424. I'm not sure if I have a 550 or a 550J. It was bought OEM by my dad and gave it to me.

Having the case open and closed don't seem to make a noticible difference. Still idles at ~45 with the case open. I haven't touched the HSF while the temp reached that high, but I did touch it while it was running on idle (~48) and it was barely warm.

I'll give Throttlewatch a try and see what happens.

EDIT: I ran SiSoftware Sandra 2004 and found out that my CPU is an Engineering Sample. That biotch at eBay sold my dad an ES! I'm guessing this could most likely be the source of my heating problem. Am I right?

 

[Sc4freak]

No, probably not.

ES is a GREAT thing. It has unlocked multipliers, meaning diverse overclocking options. You're one of the lucky few who have an ES chip!

NO kiddingthe case didn't make a difference...For all intensive purposes you had bad contact...too much AS was effecting the thermal conductivity.....

It is good you got the idel temps down 10c...It may help you get those temps in the 60's and you may be able to keep it from throttling....ONce the AS sets up a bit more (which you need to heat it up to do it) you may be able to get those idle temps in the 42-43c range...I good cooler like that should keep swings in the 17-20c range so I think 60-64c is possible...

Good luck!!!

 

[teh RedUnit]

Really? I guess my quest for cooling down my CPU will have to continue.
I ran Throttlewatch for about 35 minutes with a CPU load of about 45-65% and the Throttling never went up. It stayed at 0% the whole time. My CPU temperatures also never went past 61 degrees. The BIOS revision on my mobo is currently 1006, would flashing to the newest revision (1007) be worth doing? According to ASUS, the 1007 revision has support for newer CPUs, but that's about it as far as CPUs are concerned. I've never flashed my BIOS before, and even though I can update through Windows with the Asus utility, I'm a little hesitant to try.


EDIT: According to CPUZ, the CPU has multipliers 14-17 unlocked but I can't figure out how to change the multiplier any where on the BIOS. It's currently at 14. Am I looking at the wrong place?

I guess I should read up on Overclocking as I don't see why changing the multiplier down to 14 would be beneficial since it would just cause the CPU to run slower. Perhaps to keep the FSB from going down?

All pentium 4s have thermal throttling, not just the J series.

probably should consider up-grading to a more powerful heat sink fan combo. Ideally, you would be using the XP-120 with a 12 cm fan.

maybe see if under-volting will reduce temps, also.

The idiot here is you, I am not talking about a 2.8GHz cpu idiot, the CPU is running at 2.8 because of the extremely high temps, read well!!, so we can see that 3.4 PRESSCHOT 550 + ZALMAN CNPS700B-Cu s is very hot combination.

Nice that you read the thread before posting that someone else is an idiot when its already been corrected. It was a HSF seating issue. Go back to your hole.

 

[teh RedUnit]

If my chip turns out to really be an ES, I might consider selling it and getting a new Prescott along with a better HSF.

That might be a good move!!!!

List your system temps or case temps if you have them...Abny further move to a prescott should be avoided unless you have sufficient case cooling...

Also 45-65% is not sufficient load testing....

You should run an encoding app like TMPGenc that is HT aware or maybe superpi32mb and prime95 at same time...this will load it 100% with HT...Then check throttlewatch again....

 

[teh RedUnit]

Okay, I ran TMPGenc and prime95 at the same time for about 5 minutes so far and the CPU load was at 100%. The CPU temp ranged between 62-64 during those 5 minutes. I also ran Throttlewatch at the same time and the TM1 Throttling never went up. Should I run them longer or is that good enough to get a clear indication of possible throttling?

 

[Duvie]

run for 30min.....

 

[Sp33d]

dont sell the ES if it is one. Those are better than any P4 u can buy, bcuz they are every P4 out. If you got decent cooling, a better case, and mb wc, you could have a 4.1 ghz pc by only changing the multi to 17

 

[Duvie]

NOt all ES were and are great ocers....It could be an early generation....It does offer nice functionality though....

I think case airflow is an issue and will be for any Prescot you may go to....

 

[Sp33d]

btw, what case do u have?

 

[teh RedUnit]

Bummer! I'm also asking around in 2 other boards at the moment, and I think the consensus is pretty much to try a better/newer HSF. My case has good enough air case in my opinion. I have the Thermaltake SViking VA400BWS. I use SATA drives, so there are no big cables blocking the air and I also zip-tied most of the cables out of the way.

Right now I'm running the two programs again and the temperature is listed as 62 degrees. At this time I can touch the Copper fins on the heatsink and they are barely warm to the touch.

 

[Duvie]

Still list case or system temps...simple request...

The fact is most extreme prescott heat issues at default vcore come from ppl who have poor case airflow....You may think it is fine but for most p4 systems you need a lot of fans.......I would probably have a minimum of 4....1 intake down low in the front...1 intake on the side blowing onto agp/chipset.....and 2 exhaust out the rear or on eout the rear and one at the top of the case (only if the power supply doesn't have an intake fan here.....


In this case 62c is getting much better and I think the temp is likley a bit suspect...If it is not throttling you will be fine...I wouldn't recommedn you OC unless you see what you can get with no additional vcore....You have no headroom....

 

[stevty2889]

I also have a 3.4ghz LGA775 prescott. I was using a thermalright XP-120 and my load temps were getting up to 72c with throttling kicking in at 70c. I had it underclocked to 3.2ghz by lowering the FSB, and it was still getting to hot. Nothing short of water cooling kept this thing from throttling.

As for it running at 2.8ghz, the 3.4, 3.6, and 3.8 allow for the use of the 14x multiplier. It should default to 17, but it looks like your's is defaulting to 14, you should be able to change it back to 17 in the bios. None of the multipliers in betweeen work on mine, only 14 and 17, and it's a retail chip.

Where did you get your 3.4 from? If it's a retail chip that you bought directly, then I would contact Intel's tech support. I contacted them about mine, and they offered to replace it if it was a retail chip, but I got mine from e-bay for a good price, so I just kept it and went with water cooling.

 

[Extraordinary Cow]

I know a friend who had a 3.2 LGA775 I think it was, and it idled at 40. (My Athlon XP 2400+ hits 75 under load lol). It's good you solved the thermal grease problem, I think that's what I did to screw up mine. My friend's hit nothing about 65 - ever. Not even after running prime95 and the highest possible vCore (don't remember the mobo) for 24 hours (idiot lol).
An ES?! I've heard mixed things...if you want to keep it...then keep it...if not...then don't.
