Pentium D 805 4.1ghz

[gmc]

I read the article about the Pentium D 805 2.6ghz processor being overclocked to 4.1ghz per core!! Being amazed and curious I was wondering if anyone has tried to copy the article with success. I'm looking at upgrading my old pc. I do a lot of 3d animation and the thought of dual 4.1ghz cores was quite hard to believe. Would i really see a huge increase in performance instead of buying a normally clocked dual core. I mean..118$ for a dual 4.1ghz is awesome. What about life span?

 

[shadowjagans]

just go C2D, E6300 is way better and a great overclocker

how dose c2d preform so well for only 1.8 gh? or any of the c2d line up for that matter, what did intel do right?

Get a Core2, even an E6300 and on stock it will outperform the 4.1 GHz 805. 4.1 GHz look mighty but the P4D 805 is the WORST dual core available and even this clock speed can only beat nothing but the lowest AMD dual cores, the X2 3800+ or 4200+ ON STOCK of course.
Add to this an elevated power consumption, heat dissipation, $100+ for the watercooling (you need it to run the 805 @4.1G); it really is the worst dual core buy you can do.

jus like how the x2 3800 and x2 4200 beat the pd805 at 4.1 here rite?

lik said above, get a c2d, out performs everything and when u overclock a e6300 with water cooling ull get much better results then an 805 at 4.1

what I wrote here means the 4.1 G 805 beats the 3800+ and 4200+ not the inverse, you missunderstood me. Considering the extra $100 for the watercooling and te about 30% of chances to get to 4.1G, even the 3800+ and 4200+ are beter alternatives; OC-ing the 3800+ to 2.6G performs as well as the 805 to 4.1G

 

[SidVicious]

Watercooling an E6300 won't be necessary as the motherboard is likely to top out long before the CPU hits the thermal wall due to the low multiplier, 7x 400MHz yield only 2.8GHz, that's far from the point where air cooling can no longer cope with the heat.

I like how not too many people actually answer your question, and right off the bat they go recommend something else.

4.1ghz is tough on that system, I went for it and I had alot of heat issues. However after playing around with the system for a bit I have it a 3.8 ghz and its runs perfect. Life span? I'd say no more than 2 or 3 years, but in 2 or 3 years I'll get a new rig anyways.

 

[shinigamiX]

Isn't recommending something else also a way of telling them that there are better alternatives? Besides, buying a D 805 to overclock is smart if you plan to do just that... overclock. You'll need to be lucky, not to mention patient. And even at 4.1Ghz the performance is nothing spectacular, and the noise and power are something you should consider. All in all there are far better solutions out there, such as the previously mentioned X2 3800+/4200+ or the C2D E6300/6400.

 

[dameon51]

Luck has little to do with it. And besides, he didn't ask for a cheap CPU with good performance, he specifically asked about the 805 D's overclocking capabilites. Recommending another CPU doesn't give him the information he was asking for. And benchmarks\statistics don't lie, the 805 overclocked to 3.8-4.1 ghz is a fast CPU.

Thats simple its to keep people from making a horrible mistake The D805 was a great CPU till the day the e6300 was released. There was no greater D805 fanboy then me even before the toms review but you people need to learn to let it go and look for other values
A d805 now is a terrible choice its too late to jump on that bandwagon I ask myself why would anyone consider the d805? it has to be because people put to much faith in those reviews.When they first come out i guess its fine but how many months has it been? point being now that the d915 and d945 are out they are far better choices. The d915 cost less then the d805 cost when the article was printed, it also runs alot cooler and in most cases overclock better.


I have to agree that the e6300 is a better choice if you are planning an overclocking setup from scratch. but as far as performance a d805 overclocked to 4.1 is a far better performer then a 3800x2, I dont know how many threads,articles have been posted all over the web but its about equal to a 2.6ghz x2, that both will outperform a stock e6300/6400 but thats about it.

 

[joefriday]

I ask myself why would anyone consider the d805?

Well, I could hazard a few guesses.

1. Maybe someone doesn't want to pay more than $100 for a CPU. No matter how much better an AMD X2/Conroe/PD9XX is, they cannot be purchased for less than $100. The price competitors for the D 805 are all single core processors.
2. Maybe someone uses mostly multithreaded applications as their most strenuous CPU-related task, such as Nero Vision Express, DivX, DVDshrink, Photoshop, etc.
3. Maybe someone wants the performance of a 3.8GHz Pentium 4 in those said applications without having to pay the high price of one.
4. Maybe that person is me and undervolted the CPU to 1.125 volts, dropping the TDP to 58 watts (according to extreme PSU calculator), giving the quickness of a 3.8GHz P4 with power consumption of a Northwood.

 

[dameon51]

Exactly.

And before AMD cut its dual core prices; for few extra bucks you can also take an X2 performing much better.

nice try:

well the only guess that has an validity is #1 and even that is slow minded point of view because the D805 was all about performance for cost.
as far as 2,3,4 you can do the same thing with all other cpu's
And if you cant afford the $20 plus tax to move up to a d915 I suggest you save your money and pay some bills first or buy some food. I can understand the e6300 since it is little more money but Sorry the d805 is trash now and for temp difference of the d805 90 nm b0 stepping to the d915 65nm c1 stepping +L2 and a 12 or 14 multiplier, also water-cooling not being necessary its just common sense either you have it or you don't

the only issue i have with that is i had a (939) 3800 x2 but could not overclock past 2.6 Ghz and it could not outperform my d805 at that speed . From what i understand AMD is more dependent on date code's and steppings unlike intels that oc verywell regardless. But it you can get an x2 to 2.9-3ghz that would be sweet, I also dont know much about am2 what kind of oc'ers are they?

You should consider an extra $100 for watercooling if you want to get 4.1G out of it and it gets $200, just like a stock 4400+ or E6300 and you can OC them to perform better than a 4G 805 just on air cooling.

yep my d805 is on water (corsair)and my d915 is on air (big typhoon) and the both run about the same temps, the d915 being a littler warmer

Huh? I thought AMD's X2s were super high priced before Core 2... over $100 more than the 805D

 

[barryvenison]

Hi all, Muggins here just went to town after reading that article.

I have the opportunity to return the 805 d, it's still in it's box, and it was an A0 anyway!

I bought

Asus P5WDG2-WS
2x Corsair 1Gb CM2X 6400 C4 PRO 4-4-4-12
Big fat Zalman cps9500AT
3D Fuzion Gforce 7600GT 256MB (could send this back too?)


I'll spend about 150 pounds if necessary, what's my best CPU option?

I want to do a bit of simple overclocking, not worried about noise. Am I OK to just go and buy a e6300 and carry on, or is there an even better option for around £100 - £150?

Thanks

 

[icbluscrn]

well will that extra 150 pounds get you into a conroe e6300? if it does not the D915 for sure then spend the extra on a better video card.
Me personally since lately i have been mostly playing games and some benching, The one thing i do know is that, In benchmarks the d805/915 keeps up with my stock e6600 I would rather go with the d915 and a better video card then a conroe and worse video card(since thats pretty much the most important part) thats just me

 

[barryvenison]

Thanks!

Is that card bad? It was nice and cheap at £75 I thought I was getting some bang for my buck.

Ok, so lets say I buy a 915 if it's cheaper, what's the next graphics card up and how much is it going to cost me?

 

[joefriday]

LOL! :lol: Allow me to debunk all the BS you're spewing:

well the only guess that has an validity is #1 and even that is slow minded point of view because the D805 was all about performance for cost.

Uh huh. Right. Show me another sub $100 processor that performs as well as the D805 in multithread applications. You're not going to find anything.

And if you cant afford the $20 plus tax to move up to a d915 I suggest you save your money and pay some bills first or buy some food.

Oh, I can AFFORD a faster processor, it's just that I DON'T WANT to spend more than $100 for a CPU. Besides, the Pentium D 915 costs $128. That's 40% more money to buy one over the $92 D 805. Stop smoking crack. It's not even in the same price range.

I can understand the e6300 since it is little more money but Sorry the d805 is trash now and for temp difference of the d805 90 nm b0 stepping to the d915 65nm c1 stepping +L2 and a 12 or 14 multiplier, also water-cooling not being necessary its just common sense either you have it or you don't

The Pentium D 805 and the D 915 both have the same TDP... Guess there goes your theory that the 915 runs cooler. If you overclock them, yes, the 9xx processors will scale better with less voltage and therefore run cooler, but at stock levels, the temperature difference between the 805 and the 915 is nill.

As for the watercooling issue, it's not my problem if you lack self control and try to overclock the D 805 to its max instead of sticking with a more mild overclock to around 3.33 GHz, which is do-able at stock voltage, using the stock heatsink and fan, and allows the D 805 to run as fast as a stock Pentium D 930 or X2 3800. Let's see.....X2 3800 performance for $92? Sounds good to me. The value of the D 805 only goes bad when you don't know when to stop overclocking, and start buying aftermarket cooling solutions to push it further.

BTW, the L2 cache difference between Smithfield and Presler barely matters. Look at the performance charts for the D 820 vs D 920.

True, but I don't plan you overclock it to 4.1GHz. I understand the OP want's to OC that high, but my post was directed at IcBIUScrn, who said he can't understand why anyone would still want to buy a Pentium D 805. As for the OP's desire to clock an 805 to 4.1 GHz, I agree with everyone else here: It's cheaper and smarter to purchase an E6300.

Damn Right! I have a 805 Running right now next to my E6300. It's like an oven in the case there. It runs hotter and slower even tho it's 2.66 vs. the measly 1.86 of my C2D. I didn't oc it cause i'm not into that...yet.

Don't waste ur money! Go E6XXX. This thing is soo freakin' fast.

Found these on the charts:

 

[icbluscrn]

in the world of cpus they are both in the same price range Maybe not your price range but they are both in the low cost dual core. and stock the d915 is a better performer ,overclocked the d915 is a better performer.
again if you cant afford the difference you shouldnt be buying a cpu.
and it was not about self restraint when overclocking it was about performance for the cost because the D805 cost $130 water cooling $150 and you had fx60 performance that was $800,The d915 is even better. Now the d915 is $130 and a $50 HSF you can have better performance
