PD-805

I was going to buy a PD-805 or 820 after the prices dropped (Jul 23rd).

On NE a PD-805 is selling for $104 and on ZZF for $103. I don't remember, but is this a lower price than last week? How long should it take for this price drop to fully hit the market? One full buying cycle? Or might they drop now? Also, what are your experiences in buying from eBay?

Thanks for the input and info! 🙂


Edit:
Oh, and this is not for a new rig. I have a SFF with a socket LGA775 sitting around that I was wanting to put together for cheap.
 
If its an SFF, you better get a 9xx core. The 8xx run so hot that you probably can't keep it cool enough to not throttle.

Agreed...an 8xx core in a SFF is not a good idea at all!
BTW, have you checked that the bios of the SFF board will take a PD?
 
The chipset will take only 8xx series PD's. My other options are P4's or Celerons.

It is a Biostar IDEQ 220T.

The product page says it supports only Intel Pentium 4, Prescott, Celeron, and Celeron-D Socket...are you sure it takes Pentium D as well?
 
then you better go 6xx series P4's, I have heard they run cooler than the 5xx series.

I asked around here a while ago while I was planning this, to check if the chipset would take PD's, and it has been confirmed that it will.

You really think a 2.66 PD will get that hot? I am not very familiar with Pentiums so I will have to trust ya'll on this one.

The 6xx series are 65nm, so they should run quite a bit cooler than the 5xx series 90nm P4's. They are about 2x the price though. 🙁
 
I have an 805. The stock cooler was running 65c in an open case. If I tried to OC to 3.0 ghz, it shutr down due to heat. And at 65c, it could have been throttling.
 
the 805 is a bad chip - sorry it is - all the smithfield dual cores are bad - actually twice as bad as a single core presHOTT (no need to justify that claim - widely viewed as the worst intel chip ever made) - it gained notoriety because if you can tame the heat it will overclock alot since it is so slow at stock, but the $103 price tag will move quickly up in the form of energy bills. i ran a single core preshott 3.2E at default voltage at 4ghz in a video edit system that sometimes pounded away at 50% - 100% load for 12-14 hours a day and our electricity bill went up about $30/month.
 
It looks like I might go with a 631 then. Thanks for your input Mark and Viditor.


Plester, I think if you ran any CPU @ 4Ghz, 50-100% usage, 12-14hrs/day you will see much higher energy bills. Don't act so shocked. The $103 price tag on the 805 is a very good price considering its competition and quality. Not everyone runs 4ghz overclocks and does media encoding all day. It may be news to you, but even AMD processors or new Core2's need electricity to run. 😉
 
If you don't plan to overclock or you plan to do non-gaming tasks....the 805 is still very good at stock speeds, even with the stock HSF.

I've been planning on getting one for some time now.
I'm finally gonna do it next week...can't wait...and dual core for only $104 (maybe less)...
You can't beat that price!!

The 631 is a Cedar Mill core, 65nm, so you better verify that will work before you buy it. I definatly wouldn't stick an 805 in a SFF case either, runs way too hot.

Well, I own an 805, and even at stock, its a furnace, and throttles on the stock hsf. For $153 for an X2 3800+ there is no way I would ever get an 805 again.

IDEQ 220T
Processor: Intel Pentium 4, Prescott, Celeron, and Celeron-D
Socket LGA775 processors 800MHz Front Side Bus

Chipset: Intel 865G + ICH5


Intel 865G chipset:

Benefits:
Platform longevity with support for Intel® Pentium® D processor 805 and 820 sequence, delivering improved system bandwidth.

Processors:
Intel® Pentium® D processor
Intel® Pentium® 4 processor supporting Hyper-Threading Technology
Intel® Celeron® D processor

Doesn't say anything about 90nm or 65nm. It does show that it supports Prescott though, so why would they have support for Prescott if Prescott CPU's are too hot to use in the device? I will not be using it too much or for any real heavy work.

I have seen the internals, and it has an entirely copper cooler (I don?t remember if it had heat pipes or not) that lies in the back/center of the case exhausting the heat directly out the back of the case. (pic from biostar site) Not too bad of a design for SFF it seems.

The 805 is 2 prescott cores packaged together..one prescott is hot enough, 2 of them in a low airflow situation is nothing but trouble.

its your money - i stand by my statements tho - the 805 has one (1) thing going for it - its cheap to buy - cost of ownership is another thing entirely. look at the power draw of the smithfields in the various reviews - not good.

Not to mention the 4 ghz bs thing. You need a big power supply, and watercooling to get there, so thats WAY more than the extra $50 the X2 3800 cost, and at 2.6 beats the 805@4.
 
I'm buying an 805 as well.
What I want to know is what kind of performance I can get out of an ASRock 775Dual-VSTA motherboard.
How high will that board allow me to take the FSB and hence the overclock on the 805?
I've heard of only getting as high as:
146 FSB * 20x Multiplier = 2920 MHz (2.92 GHz).

Is this true? Can i take it higher on this board?
