Been fiddling with trying to achieve some stable overclocks with my P4C 3Ghz system

With a 10%OC 3.3Ghz, 880FSB I get the following temps
CPU Idle 39C, Load 50C.
Mobo 32 constant
Vcore 1.58, max 1.6

For a P4 are these ok?

Sound acceptable to me.

Mines full load -22 ;)

Si

I did'nt want to know that :rolleyes: unless of course you want to swap rigs :p

For a price i would consider :) yes

You pay me 500 quid :p

Seriously, these temps ok?

Is yours water cooled Si?

Those temps are fine for a P4 Neil, no problem at all. :)

Rik - if he's going below freezing, there's much more than just a watercooler on it. That's more like Vapochill/Prometeia territory ;)

Si uses a Prometeia. He got one a while after I got my first one last August. He is also more than likely reading the temp off the front display, which is nowhere near the actuall cpu temp. Under load with a reading like -22, he is prob hovering around the -11 to -8 mark under prolonged load.
If he is overclocking, otherwise, he could well be close to -22 actual cpu temp.

BTW Si, how long did it to take you again to get your complete machine working? LOL ;)

Cheers,

Nick.

P.S. If that is a retail Intel heatsink on there, then 50c prolonged load temps are just fine. Hell, I have seen 3.06 cpu's with stock sinks sitting at upto 55c under load before.

Si was reading the temp from the motherboard monitoring software, it was reading at about -35 with no load.

I sit at a -10 or so with no load and about -1 or so max'd out. But I'm running a meer VapoChill PE. Mind u the P4 is sitting at 3.9G and a 258FSB :)

Steve

is he using MBM? TBH I would be surprised if that core temp is accurate, as I have built these prommys now in various forms so have a fairly good idea of what temps I am used to seeing. I still don't put much faith in the sensors even now tho, as you prob too m8.

BTW, My new rig build starts shortly as my custom special has now found a new home with her new owner in portugal. Can't believe I let her go after all of that work I put in :( Heyho :)

Another project is always good :)

Cheers,

Nick:)

He was using the corecell app which comes with the MB. It does seem that the Canterwoods are a bit hit and miss with reading temps. The only board which looked even remotley accurate was the Gigabyte 8KNXP. Very good board shame the VCore is locked at 1.60.

The IC-7G I run is a bit iffy temp reading wise but who knows.....its stable, and seems to run quite happily.

The water cooling for the GFX and northbridge also does a good job, the water is getting a bit hot but with a core running at way over 450 every day, I cant expect to much ...22,000 3dmark on day to day settings :)

Steve

5900 stock or Ultra? not that there is really much in the 2

I want image quality as well as speed so its a 9800Pro :)

Having seen the majority of recent reviews there doesnt seem to be alot, if anything, in it speed wise between the 9800pro and the 5900 ultra. They both have strengths and relative weaknesses.

Steve

Monkeh, you should have been more descroptive when you said GFX. When I see GFX nowadays, you think Geforce FX m8 ;)

I thought you had a 9800pro, as Si was whittering at me at how he had a new person to worship that had a faster machine than me LOL :)

Ah well, my new one should be built within about a month :)

GFX = Graphics Card ;)

I havent tried maxing out yet, have had 22,500+ but could probably go higher....my main aim was to get a nice quiet system that was quick. Seem'd to have done that..........

Steve

For once nick take your from your arse, and stop being a ****.

No the temperatures we not taken off the front. But i fail to see what it has to do with you anyway.

Sorry Si, I keep forgetting how you are held in such high regard on here m8 and haven't been a leech most of the time since your joining. I have problems with very, very few people on here, but Having to listen to your muppet like antics over the last year or so has done that to me. Why do you think I have blocked you for all these months??? You ask questions, or ask for help, can't be bothered to do things properly or disagree with the advice given. Round and round we go........... I just hope you have changed for the better now.

LOL, you didn't have the first clue about any of this before signing half of us up on Messenger m8. You tried running before you even knew how to walk properly with this stuff and you always, always ended up blaming your equipment. You put the necessary hours in, the necessary research in and do things properly, then things work, but how many times have you learned the hard way.

Sorry guys, not meaning to make this this some childish public slagging fest, just fancied a poke :)

Then poke in private :p

Back on topic..

So 50C under load is ok. What's the max before it starts to affect longevity?

Well you can go by Intel specs, or you can go by other User's experiences. I have found that especially with a load of our P4 Work rigs, that if you keep the temps under 60c, at least according to the sensors, they seem happiest and run at a consistent speed. When ours used to go above that, the speed would be affected slightly. Seems odd that the throttling technology would kick in so early, but our experiance at work anyway with Northwood core P4's.
Voltage is the thing to worry more about m8 IMO. Without really high flow aircooling or watercooling, I wouldn't recommend over 1.7-1.725v absolute tops on the core. 1.7 ideal max. Even with phase change and exotics, many people have reported SNDS (sudden Northwood Death Syndrome) when running 1.75V or above. Not entirely sure if this still occurs, but was quite a talking point on forums I sit on earlier this year.
I would say IMO 1.6V and below will have no noticeable effect on the lifaapan of the CPU, just keep the temps around where they are now.

Your thoughts Jinxy?

Edited for pish poor typos

50 is fine, the P4 is a lot more resilent than the AMD chips to heat. From my (limited) experience of the P4 I seems that the throttling built in does a good job of stopping the chip from frying itself. The AMDs on the other hand would fry them selves withing seconds if the temp went to high.

With all this stuff there are other ways of dropping temps, all depends on cost, noise and what you want as an end result. The case temp for instance can have quite an effect on overall temp of the CPU, northbridge etc so air flow is important. I got bored with chucking enough fans in my case that it made it sound like a helecopter that I went the water cooling and a Vapo unit.....

Neil

You'll change it before ya kill it :p, i built a mates p4 2.4 iirc a little while back that was 52oC under constant load 24/7 msi mobo stock heatsink/fan in a warm room with crap ventilation, some reading for ya here and here

Si

So I can go up to 70C? I suspect my RAM and FSB will crash before then.

.

[Edited by super_si - 7/20/2003 7:11:02 PM]

Realistically probabaly wouldnt crash, it depends on if your O/C'ing. If your not, then your memory and fsb will sit at a relativly low temp. Its only when you start to push the FSB on the processor and memory heat starts to really build in these components.

I've read on more than one occasion thou that the heat spreaders on the memory are for show only and make relativlt little, if any difference. The northbridge as long as its activly cooled is usally ok.

The only reason I put the water cooling on the northbridge was to remove another fan from my PC......

Steve

[Edited by J1nxy - 7/20/2003 7:19:56 PM]

The northbridges on canterwood chipsets chuck out a nice bit of heat. Yeah Jinxy, Ramsinks make virtually NO difference on most of the fancy ram that we buy.

My northbridge is sitting at about 20c most of the time, about 35 under load, but some of that is due to the graphics card kicking out some serious heat. It was over 35c non-load and 40-45 load pre-water cooling but thats running at 255+ FSB.

The northbridge was activly cooled on all the boards I tried and didnt seem overly bothered about being O/C'd just got a bit noisy with heat sensative fans.....

Steve

[Edited by J1nxy - 7/20/2003 8:03:57 PM]

I have come across passive cooled northbridges on both the Asus P4G8X and P4C800 and especially on the P4C they really burn :D 40mm fans all round :)

BTW, what setup you running for the WC side J?

I have got a 9800Pro with Swifty MCW50-T TEC VGA waterblock, Blackice Extreme rad, eheim 1048 pump, tygon tubing, relay device, purple ice wetter etc. Not completely assembled yet as I awaiting all of the rest of the rig parts. Not cooling the Northbridge off it tho, as I want the rad solely cooled by it.

Cheers,

Nick :)

I'm running a vapochill case with the asetek waterchill system. Originally it was bought to do the cpu, but with the vapo it became redundant so bought the northbridge and graphics card block. The waterchill stuff is designed to fit into the vapo case as well which is useful.

I can get about 500 core from the gfx card and have got to get round to putting so decent heatsinks on the gfx memory but that'll run at 375ish without to much trouble.

I was looking at the swiftech block but decided I didnt want to mess with the tek as well. I dont need ultimate performace so also couldnt justify the extra 50 over the waterchill block. I'd also need to run the 120mm fan at 12v which is damn loud so another reason for no tek base waterblock.
