Intel 2.8 OC 3361.19 heating up at 72c - Help

niaxous

Hi,

A computershop oc'ed my new Prescott 2.8E to 3361.19.
Everything worked great untill the outside temperature increased to 35c, meaning that Asusprobe started to hit the alertsound at 73c/161F.
This only happens when I play Far Cry, Soldner or any heavy duty game graphics.

Normal temp is at 53c/125F, air cooling is done with the default Intel cooler.

How can I reduce this temp?
If I need to reduce the speed of the CPU to avoid high temps, so let it be.
I don't want to pay extra bucks and leave my pc at this shop anymore(I had to wait 6 weeks before getting it back!!!)

I did a system restore and it managed to reduce it only by a couple of degrees.


My system's info:

Voltage:
12V = average 12.281
5V = av 5.16
3.3V = av 3.248
Vcore = 1.504

I reduced the FSB from 200Mhz to 187 and the Vcore was set on Auto, I reduced it lower then 1.5.

Any clues??
Help would be apreciated.

Thanks for your future posts,

What type of HS do you have?

Here someone is selling a pretty good HS for a nice price.

if asusprobe is recording 53C at idle, even for a prescott, I think you're running too hot. either back off the overclock AND get a new HS, or just get a new HS

The intel one which came with the processor but I have the Zalman CPNS 7000A available, I haven't changed it yet.

Thanks for the HS offer but it will be more expensive to send it over to Europe.
Lol

I have a Zalman CPNS 7000A still available but how can "back off the overclock" ?

mmonnin

Yeah that HS would most likely be better than that stock HS. I didnt realize you were across the pond.

He meant to lower the FSB either lower or back to stock speeds. With that new HS you should prolly be able to keep your OC. The Precotts run hot to begin with.

Yep in the capital of Europe, Brussels

I lowered the CPU external frequency from 187 to 180 and the Vcore to 1.45.
Is this correct or do I need todo anything else (except the HS)?

muddocktor

Yeah, that Zalman should be better than the stock Intel heatsink. Use a good quality thermal paste like Arctic Silver 5 or Arctic Ceramique and I think you will do OK. Also, if it's still running too hot after installing the Zalman, then you might need to back the front side bus speed down a little and drop some of the overclock off, but first I'd try that Zalman.

mmonnin

Well running anything under 200 MHz FSB is lowering your overall CPU speed to below specs.

TheBaron

are prescotts multiplier unlocked??? how can he be getting that oc with an fsb of 187, and speaking of why the hell would you want to LOWER your memory bandwidth like that

This is likely a software issue, not a hardware issue. A lot of boards don't read the Prescott CPUs temperature properly. I suspect that the actual CPU temperature is 52-62*C under full load at 3.4GHz, which is acceptable, but not great.

My 2.8 P4 Northwood ran at those temps with a 400MHz OC on the stock heatsink. It's probably not always good to compare to another system, but temps here are about the same as what niaxous is experiencing. And we all know that Prescotts run quite a bit hotter than a NW. I'd stick with what everyone else says; upgrade away from that stock heatsink. It's great for handling the chip at it's rated speed, but when it's overclocked with more juice running through it, it will get quite hot.

Baron, Prescotts have locked multpliers, just like every other P4 I've seen...

Geeky1

No, we don't all know that, actually. I'm planning on writing an article about it, but so far, I haven't been able to prove that.

No, but we can take a real good guess that it will run hotter, just by looking at the TDP specs posted here of P4C's versus P4E's at the same clock frequency. I'm not so sure that the actual processor die temps aren't right, myself. I know that there has been a sizable differential in die temp vs IHS temp, but it might be attributable to the new .09 process not transferring core temp as efficently as the .13 micron process to the IHS also. I'm just making a wild guess as to that though.

Reducing the CPU Freq. and Vcore was it a bad idea?

If I can reduce the temps and play Soldner or Far Cry that would be great.
The system is working great but it just bugs me not to be able to play those games and all the other future games.
I haven't been able to find the time to fix that Zalman cooler yet.

Apart Asus Probe, I also use MBM 5 Motherboard temp utility and the temps are the same.
55c idle and 68c with a 2d game like Rise of Nations or Command and Conquer but Far Cry and Soldner it starts hiting 72c.

mmonnin

Next time you go to play, change HSs instead. That simple.

Yep but I am waiting to get paid (8 days and counting), so I can buy some Artic Silver 5 to apply on the Zalman HS.

will someone do me a favor and explain to me the difference between these 2 #'s?

System Clock : 240.09 MHz
Scalable Speed : 200.00 MHz

cause it looks like, from the data above, that the 240.9 is his fsb (because of this # System Bus : 960.34 MHz QDR). now my question is, what the hell is scalable speed? is his ram locked at 200 mhz?

Looks like hes running a divider but I don't know of any ratio that would give 240mhz fsb from 200mhz. 5:4 is close though. *shrug*

TheBaron

well but then how the hell does he lower JUST the 200 to 187 - this doesn't click right with me

croc_

Yeah, I'm kinda confused too ... that was the only thing I could think of.

croc_

Unless he is using some sort of auto overclocking? like a 20% overclock? But then how would he adjust the FSB ... hrm.

TheBaron

could that be uGuru or something like that??? a windows based overclocking utility? if thats the case then hes changing the wrong thing in order to cool his system off

Thats probably it! .... I wonder if he will ever respond? :P

TheBaron

niaxous, when you get back answer a few questions for me:
1) what mobo do you have?
2) do you know HOW the shop overclocked your computer? i.e., did they use a windows software utility as mentioned above, or do it the RIGHT way in the bios
3) what did you use to give you that system info?
4) what did you do to change your cpu freq? was that in the bios?

Prescott's Voltage compliance specs are: 1.32-1.52 Vcore. So, lower than 1.5 is not only not bad, might be dang good idea. I will give you an OC idea set, based on a Prescott 2.8.

Vcore set at 1.3875 per BIOS, actual floats around 1.31-1.36 depending on system load.

This CPU is running right now at 3122 MHz (Per BIOS), base 225 (set by me, per BIOS), multiplier allowed to float with Softmenu, comes out to between 13.5 and 14 (actual figure is 13.87555555). Corsair PC3200 LLPT RAM in place. It's been at that setting for about a week now, folding two consoles and processing and printing about 50 11 MB digital pics(2288x1712 res jpg files) yesterday while cleaning its registry, running Spybot, etc., for example. AGP and PCI are fixed at stock rates, no OCing there. RAM is at 1:1 with CPU leading ratio assignment.

It has been running at over 3200 for a week (during late May), still stable, and I reduced mainly due to OTES temps on the IC7-Max3 as outside temps climbed over 90 Fahrenheit for highs in Florida.

CASE temp is floating from 30 C to 31.5 C. Room Ambient temp varies from 80-83 Fahrenheit (yes, the AC is on). CPU temp range??? 67-68 C under about 95-97% load. OTES temp is typically 49-51 C on the IC7-Max3 board with that multiplier in place.

At a guess, scale it back to about 3.2-3.25 GHz real, it should be stable as a rock. There is a Microsoft update for high speed chips out, relating to app performance forcing the CPU into a full time 100% load-- this was rated as moderate as only games cause the issue that was patched. This CPU works best at about 97-98% SUSTAINED load max.

There have been some BIOS flashes offered by some mfr's for some mobos to handle game vs Prescott issues resulting in CPU running at 100% for prolonged times also. VERY recent ones.

1) ASUS P4P800
2)It used the OC utility in the Bios
3) WCPUID, if you have another program, tell me and I will return the info.
4)Yes, it's was in the BIOS

I prefer to use CPU-Z nowdays, as it will also give you your memory speed and timings, along with processor speeds. Here's a couple of screenshot examples of my P-M laptop. Try running it and post some screenshots of the memory speed and processor speed.

I made some screenshots of the CPU & Memory info.
See files.
I couldn't make proper screenshots so I made Word docs printscreens, could give you me a tip how you managed to get those images above, it would be appreciated.
