Pentium D temps way too high.

[AkumaX]

HAHA!

alright you know in this pic, i use a FanMate2 to control the rpm. the thing is, if i dial it to near the lowest setting, there wont be enough current going through to rotate it, so it'll just stop. so i put the FanMate setting on about 1/3 power, and went to school. but i left it too close to the threshold of having it turn off, so my temps all day were like this: whoops!

The PD 820 I tested didn't throttle on S&M either. Everything stock.

My Pentium-D 830 (measly 3.16GHz overclock) idled at 44C with the stock heatsink/fan, but it was really loud when it got hot. I replaced things with an XP-90, Nexus fan, and AS3, but now it idles at 55C. Maybe I misapplied the paste? At least it is super quiet.

And no need to put down Pentium owners. This PC is for my fiane who is a Photoshop guru, but for me I am upgrading the AMD rig.

 

[Markfw]

First, I am not trying to put down Pentium owners, but all of the current Pentiums runs hot, the P-D series are VERY hot, and they underperform, the P-D series especially, unless you application is multi-threaded. I am just trying to educate people who have listened to the Intel marketing machine for YEARS. They are stable though, I do not contend that they are not.

Note : I have a big typhoon cooler on my 820D.

As for throttling, I can believe that in a well ventlated case at stock they may not, but in a case not so well ventilated, or especially when OC'ing, they will. At 3.6 and 1.6v, they throttle easy, at idle. At 1.55v, and 3.5, it started throttling at 50c, and got down to 2400 ! If I don't run S&M, just 2xF@H, and leave it at 1.5v, and 3.43, and the case open with an extra 120mm fan exhausting, and the temp stays below 55c, I can keep it from throttling, but in that config, it looks like crap, is loud, and still get trounced by my 3800@2.55. Thats sad.

The Athlon64/Opteron and especially the dual-cores, X2 and 1x5 series Opteron, are just really the only sensible way to go at the moment for the desktop.

Mark I mostly agree, but the 820 is still the value dual core chip. If the user only has the intention of running stock I don't see why the PD should not be a viable choice.

Furthermore, 1.6V seems like way too much voltage expecially for an already hot chip!! My San Diego jumps almost 10C from stock voltage to 1.6V. The PD's are already hot to start off with, of course adding 0.25-0.3V is going to cause a melt down.

Lastly I would refine your OCing methods. Most moderate Intel overclockers hardly even raise the vcore! For example, to get to 4 GHz on a 640 it is best not to touch the voltage.

 

[Markfw]

The reasonI say the 820 is not a viable choice, it is $80 less than the 3800, and if you run it 24 hours a day, in 8 months, you will have used that up in electric bills, less if you live in a warm climate and have AC. And during those 8 months, you have 20%-50% less performance than the 3800 ! (mild OC)

As for my OC methods, 1.5 is needed to get much over 3.0. Duvie was over here and we both worked on this together for hours, so please do not question my OC method. I only tried 1.6v to see how high this baby would go, but stayed at the more resonable 1.5v, which is what it has run at for 2 months or so now.

 

[Hikari]

Oh, I agree on AMDs being a better buy, I'll be making myself an AMD box after xmas. I just get tired of flaming on some places (not saying it happened here).

How do you tell if it is throttling? Its sort of annoying having this system at 55C just idling, but I suspect I'd need a noisy fan to make that better. Ahh, I re-read, there is a program listed above. Still, my box won't even boot if I try more than 212 FSB.

 

[Markfw]

S&M will show you, but it almost allways happens on core1. Also, it seems to usually only happen in OC'ed systems unless the case cooling is bad, or its very hot ambient temps.

 

[Hikari]

Thanks, I'll check things out tonight. I think I'll double check that the heatsink compound is applied well, too. At least its a quiet system. hehe.

 

[Markfw]

see edit above, core1 is almost allways the culprit.

1. Too much paste will cause your issue. The stock hsf is not always flat, had to slightly sand two of them to fit properly. You need very little paste, bb's worth on the cpu, spread several times, cleanse it, and also spread some extra on the hsf and remove with a lint free cloth. That will fill in valleys although it looks clean.

2. Upgrade to a cooler like the Gigabyte G-Power series.

3. I use both the G-Power and Thermaltake'ss design. 840EE at 4.0ghz never goes above 53c under load, idles at 43c, in a Thermaltake Tsunami case. 820D in the same case and cooling system running at 3.5ghz will actually run warmer, idles at 41c, at load 55c in the same conditions.

 

[anandtechrocks]

Mark, I'm only questioning your OCing methods because every PD overclocker on Extremeoverclocking, XS, etc. is not running voltage greater than around 1.45V and are getting 3.8-4 GHz.

Perhaps it is your motherboard, but today's Intel chips do not seem to like voltage unless you're using phase or LN2.

Edit: Mark, don't get me wrong I know that the X2 3800+ is a vastly better processor than the PD. But for you go go around telling everyone to throw their PDs away because YOU had a bad experience with one is nonsense.

 

[Markfw]

Well, than why don;t you just call Duvie and me liars and idiots. I trust myself, and people I know, not somebody on the internet who can lie all they want.

 

[anandtechrocks]

Mark I believe everything you posted about your PD experiences. However, my experiences as well as many others on different enthusiast forums have reported different results. Like I said earlier, I just don't think it's right for you to go around telling everyone that their processor is complete crap.

 

[Markfw]

I bought this just so I could evaluate it for myself, and I have knowledgeable witnesses like Duvie, so this is verified information. I don;t care what other forum posters may say, so I have the right to post real verified results.

Mine is ~65C Idel ~75C full load but mine is OC

I easily believe that ! And you have the 840EE, not the 820. I just don;t believe that an 820D can get to 3.8 or 4.0 on air easily ! I can't get it to post at anything over 3.6 no matter what voltage, dividers, etc on the best air cooling available, and an open and vented case ! I don;t even have anything but a 1 meg PCI card to draw down the PSU, and I have an Intel chipset, and a Fortron 450 watt PSU. Anybody else here think 3.8 OC on air is common for an 820D ?

 

[Cooler]

Asus P5WD2 Premium has great OC options for any PD even for low end 820. But case you have is Key for OC these suckers you need lots of air flow I have 3 120 mm fans in mine. Best part is with Asus bios flash it will work with a Presler and even a Conroe.

I would call shens on that being the average. Possibly close to the maximum I would think on Air, or even water. Even so, a 4.0 GHz 820 is only about as good as a 2.5GHz X2, maybe a little better. But most X2's will hit that with ease, whereas P-Ds struggle to get there.

 

[AkumaX]

i don't even bother to o/c my 820D anymore. it'll just suck up more energy for me to pay, with a very minimal performance increase.

 

[Bingo13]

I just don;t believe that an 820D can get to 3.8 or 4.0 on air easily !

I can run the 820D at 3.738 at 1.45v 24/7 with out an issue. I can run it at 3.850 at 1.4875v with out an issue on air and never exceed 55c. I run the 840EEs at 4.0~4.2 on 1.45v and have yet to exceed 53c on air. The secret is the power supply, good board, cooling, and the MCH voltage.

I don;t care anout a $1000 chip, I said 820D. Are you saying that you have an 820D@3.738 at 1.45vcore ? at full load ? running what ? Full specs please. Are you saying a fortron 450 isn;t enough to get to that speed with a plain 1 meg PCI card ? And are you saying intel chipset motherboard isn't good enough ? And the Big typoon isn;t the best air cooling you can get ??????? Tell me where I am going wrong then.

And if we post our X2 issues with several games and applications what are you going to say? I mean if you do not like the Pentium-D series, that is fine but if people are asking for assistance then your course of action should be to help and if you cannot then respect the personnel who are trying to at the very least.

 

[Markfw]

I have the X2, several of them, and I have no problems, and most people don;t either when they put the patches and the correct drivers in.

And where did that come from ? will you answer my questions ? You say you can OC an 820D to 3.738 at 1.45v ? How, you tell me where I went wrong.

The first two numbers I posted are 820D chips. I can run any game, application, or benchmark I know of at this time. I threw in the 840EE as a comparison. I would not call the Big Typhoon nor the Fortron 450 quality components but that is my opinion. I certainly would change power supplies to either a OCZ 520w or Power PC 500w+ and since I do not know what board or memory you are using it is difficult to help you. Who knows, you might not have locked the PCI bus so you are having issues with that setup. Anyway, the draw from a PCI-E card is not going to affect your numbers as I can run two 7800GTXs in SLI and not have an issue with the mentioned power supplies.
