My New Pentium D 820 Rig

After hinting in a couple of threads about my rig, I think it's finally done. (At least until I get the upgrade bug again..)

I'm a hardcore AMD user. I've had a jillion AMDs and o/c'ed them all and etc, etc...

But the X2 was just out of my price range. However I was seduced by Dual Core action. So I did the only thing I thought I could do...

Get an 820D.

Yeah, we've seen it all. It's freakin hot. My electricity bill will go up. It's way slower than an X2 3800+. The 3800+ is good enough to take out 820, 830, and most of the time, 840 Ds. And that's without overclocking it!

But I just couldn't bring myself to spend $350+ on a processor. Even though 99% of you say its worth it.

So instead I found the cheapest rig without having to upgrade much.

CPU: Pentium D 820 (2 x 2.8ghz 1mb L2 cache)
HSF: ThermalTake Big Typhoon
Mobo: Asrock 775-Dual880 Pro (PCI-E and AGP, DDR and DDR2)
Ram: 1gb (2x512mb) Patriot LL Ram 2-3-2-6
Video: BBA ATi 9800 with CoolViva VGA cooler
HDD: Maxtor 250gb 16mb buffer IDE 7200rpm
DVD: NEC 3520A
PSU: Seasonic ***w Silent blah blah blah

I already owned the Video, HDD, DVD, PSU, and technically the RAM from my last right (a 3200+ S754). The Ram thing is interesting, because I had PQI DDRII-667, but it got unstable when I underclocked it, so it had to go back.

I'm glad I didn't have to upgrade my video card to PCI-E or get DDR2, because that just adds $$$ when you already have it (a good thing about getting S939 boards like the Neo2)

I was going to get an XP-90 or XP-120, but I've been hearing too many stories about this thing running too hot...

However it is still pretty hot. Averaging 53c idle and 73c load. That's going to take getting used to..

Here's a CrystalMark screenshot:

CPU-Z Validated

I suppose I could o/c it higher, but I really don't want to get it too hot...
And as you can see, it has no idea what ram I have. When I had the DDRII in, it said my ram was at 1.5-2-2-6. Right...

I hope its running @ 2-3-2-6, but there's no way for me to tell.


Honestly it feels like a 2.8e w/o HT. But when I do two things at once, or use TMPGEnc, I could see the difference. The main thing right now is my HDD. It's too slow, or I need a new scratchdisk. I tried NeroBurning and using DVDShrink and my HDD was crying. However, Playing WoW and CS 1.6 both in windowed mode was fine.

The biggest reason for me getting this rig was the price. I couldn't pass up an 820D for ~$137. Also, getting the Asrock mobo for $62 (no tax for me) went well since I wouldn't have to upgrade video/ram. I would have had to get a new HSF even if I were to get another CPU to o/c anyway. Cheap dual core? Sure. Even when its overclocked, it probably won't ever hit X2 3800+ performance level. But for 1/2 the price, I said why not.

edit: put AutoGK score in AutoGK thread

during the time when i was seriously considering the x2 3800+ (and enter more credit card debt), these are the prices i would have gotten to get that rig:

x2 3800+: $340
big typhoon: $48
msi neo2 plat'num: $80
============ $468

where as the same components that i got the 820:

820D: $137
big typhoon: $48
asrock 775dual-880: $65
============= $250

that's 53% less than the 3800+, for (honestly) 53% of the performance. but at least it's dual core? i also need to factor in electricity...

also no throttling here w/ throttlewatch, bounces back n forth between 2793 and 2820.

Questions are welcome :)

no fanboyism here, that is a sweet rig, nice job

have you roasted marshmallows over your HSF yet? holy canoles! 73C!:shocked:

Well, you prefaced your post very well. As you know the 3800 is faster, but what I would really like to see is someone who has both to bench/use and give feedback. When you get some more $ and the 3800+ comes down. Get one, and sell that flamethower, and then tell us what you think !

theman, thanks :)

the cobbler, i want to cook an egg!! but the HSF is actually pretty warm to the touch... the HSF on the video card however is blayzin' hawt

Furen, i hope its sensor inaccuracy! the 820 is the only one in its line that doesn't have SpeedStep, so no throttling for me :(

Lithan, ASROCK!!! (it looked like a promising mobo, considering i didn't have to upgrade video/ram) newegg link

Markfw900, yeah, i really wish i had $$$ for the 3800.. i honestly don't expect to be outperforming any of you guys (i mean, my dual SuperPi score was 40 sec(!!), where as my SuperPi score w/ my old 3200+ S754 @ 2.35ghz was 37 sec). but i think this will tide me over for now...

Speedstep is not Thermal Throttling, but rather demand-based throttling. Most netburst CPUs (the Willamette was the exception, I think) have thermal throttling built in, which means that if they reach a certain case temperature (this actually varies from CPU to CPU but is close to 70C on most Prescotts) the CPU starts skipping clocks in order to lower temperature. It does this without lowering the reported clock speed but it does have an impact on performance. Demand-based throttling (Cool and Quiet, Speedstep, PowerNow, Demand Based Switching) actually lowers the CPU's multiplier when CPU load is low, so your operating clock speed does go down.

Wow !!! $58 motherboard ! And you got the 820D for $137 ? where ? for those prices I will try one just to tell everyone what I think ! (too much money, and not enough reason to spend it)

whao, what program can i use to see if it throttles?

eBay!

I have seen some screamin deals on ebay as well...I bid on one a week ago but lost out...I would have won for that price...I would definitely get one at that price to play with...

Like the Typhoon??? I want to try it out on my X2 now....

Well, I just got one on ebay for $158.79 and $8 shipping. These must be real crap if they are dumping at this price. But Now I can be objective when I badmouth these !! And I can see what they OC to ! I will use one of my existing XP90's to cool this sucker. And I think I will use that $58 mobo you got ! I hope they OC OK.

Damn, Mark has far too much money :p

Looks like a great budget dual-core machine, AkumaX.

Well I'm sure that in a few months, that X2 would have bought itself based on how much you'd save on the power bill.

lol, i actually did factor that in, since i don't pay for power now ;) but once i move, X2 here i come!

And I did this mostly so when I badmougth this sucker, people won't accuse me of being a fanboy. Also, I want to know firsthand how bad (or good) this sucker is !!!! stay tuned...

We built some 830 D boxes for a client and they initially had crazy overheating problems with the stock sink. Using XP-90Cs, we go the load temp down to around 63Cish. Just a thought if you are worried about that load temperature. Intel's docs say that 69.5C is the max for Pentium Ds.

hope you have good luck w/ intel rig! i was about to get that ecs 945p-a also, until i stumbled upon that asrock. lmk what o/cing options are in there, if its an award bios i might be able to unlock some stuff ;)

Yup, its a crapshoot, since almost nobody is venturing here (I don't blame them). I will post another thread once I get it setup. Since I expect nothing, anything positive will be welcome. I am just getting bored, since Intel has nothing to offer right now. So this being the only cpu anybody is buying, I want to see if its worth the $170, even at ebay prices. What I know from the past is, if its this cheap on ebay, there is a reason. I want to find out.

Half of it is probalby Intel employees breaking the rules. We get discounts but it's against the rules to sell them.

It may be the people are selling 820Ds on eBay if they prove to be poor overclockers.
