4600x2 or Pentium D820?

[Jeff]

Which one should I treat myself to next? http://www.adventurevision.com/smilies/chin.gif

I'm 99% sure I know the answer, but I'm soo Pentium ignorant it isn't funny. ;) Right now I can get either of those with motherboard for ~$250 so it's just a matter of performance. I'm thinking the only thing the Pentium D would do better is SoB.

[the-mk]

I'm not in SoB, but how would one of these new Intel Core 2 Dou perform there?

E6600 @ 3.0GHz 5million/sec each core

[MerePeer]

Not sure if this is the best way to know(?), but if I look at the SOB Preferences page for each core of an 820 (2.8g) the cEM/s are 1918522 and 1619039. The E6300 (1.8g) has 2799711 and 2165555.
C2D + mobo = $180 + $50 = $230
Mobo here: http://www.newegg.com/Product/Product.asp?Item=N82E16813135023
Not O/C. Linux O/S.

The 820, 6300 and 4600 are all in this comparison report w/different pgs of benchies: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2795&p=8

Tom's has a neat comparison tool that includes the 820 and 4600 and (6400): http://www23.tomshardware.com/cpu.html?modelx=33&model1=477&model2=448&chart=174

Maybe someone can post 4600x2 SOB nos?

Helix,

Can you post here some benches of your Conroe when running Sierpinski/Riesel Base 5 sieving? Thanks.

Be careful comparing numbers if the OS isn't the same.
Linux scores quite a bit less than windows in SOB.

Running windows a stock 820 will do 3 to 3.2 million per core.
You can get 3.5m a core with a mild overclock to 3.2ghz.
A good MB with highspeed Dual Channel DDR2 can add up to 10% to those figures.

The X2 4600 will do around 2.8m a core at stock.
Around 3.2m or so overclocked to 2.7ghz.

Running a single instance on any of the dual cores AMD or Intel will always show higher numbers than running 2 in parrallel.
There is no contention for the memory BW so of course a single instance will perform better.
Beware of this a lot of folks post benches of SOB running a single instance on multi core CPU's.

Whatever chip you decide on make sure the MB has an Intel chipset for the 820 or an Nvidia chipset for the AMD.

Memory performance is critical and most VIA/SIS chipsets run single channel.
This is the kiss of death for a dual core.

Which one should I treat myself to next? http://www.adventurevision.com/smilies/chin.gif Get (me) one of those Core 2 Duo Intel (http://www.free-dc.org/forum/showthread.php?t=11762) rigs would ya? ;)

[PCZ]

Well if you get the 820 you will never need to turn on the heating in your room again. :)

The Intel dual cores are powerful CPU's, they just run a bit on the warm side
Especially the 90nm ones like the 805/820.

If your budget can stretch to it get a 945, thats an excellent chip.
65nm so it runs quite a bit cooler.
2x 3.4ghz stock 4Mb cache.

[Jeff]

Thanks for the great input... those Duos seem pretty interesting. I'll do some more checking about before I press the "buy" button. ;)

Thanks again. :cheers:

My E6600 at 3.6G gets ~ 6.2 M/sec each core. :rock:

By the most awsome looking to run is the DC W/HT DP xeon system running at 3.2Ghz. So how many cores does it take to do SoB?

Jeff,

do you know if that board is good for overclocking ? For $49 it would be a steal if it did..

Let us know hot it goes..

@ carlos. How do you get benchies from Sierpinski/Riesel Base 5 sieving??

and did i ever do sieving?????? :)

To start the client create a batch file with the following text:

start /min /low sr5sieve.exe

Run that batch file, wait 6 min and give me the sieve speed in p/sec.

Some overclocking, but not much from what I've read. Supposedly there isn't a Vcore adjustment but that should be able to be bypassed with a resistor or maybe a couple tiny pieces of wire. :)

I went with the E6400 because it's a higher multiplier just incase this mobo is a POS.

I'll be sure to report back. :beep:

[PCZ]

Good luck with the VCORE mod.

I have 2 of them, not exactly the same model but close enough.
Mine are M1-s DDR2 only, otherwise identical.

You can take the FSB up and down which is good but no VCORE adjustment.

BTW there aren't any holes in the socket with 775 so no where to put the wires :)

The 8xx series are 90nm parts and can run very warm and use lots of power. The 9xx series was the die shrink to 65nm. Much cooler and better overclockers. I think the low 8xx series runs around $100. If you can afford the $200 range for a processor I would go with the low end Core 2 Duo. It's much lower power and does great on just about any crunching. And with a good board can overclock just as well as a 8xx series. In my opinion the Core 2 Duo's do more work with less heat and lower power usage.


em99010pepe, after I did the screen shot I flushed the caches since the system drive was a clone of another system already running SoB.

[Jeff]

"Your order has shipped." :woot: :woot:

what is it? a Core 2 Duo?

[Jeff]

Yep, the E6400 to be exact. ;)

Don't all those 17s in the tray bother you? I've got two Prime95 icons in mine and I'm already concerned about consolidating the damn things.

[guru]

It's running remotely in my lab. All it's doing is SoB.

[Jeff]

They're here... :)

[Bok]

Cool. Let us know the overclocking potential...

[Jeff]

Mobo sucks butt. :( Can't even install the video driver. PCI lock doesn't exist. Overclocking ceases over 290MHz FSB.

BUT, after saying that... I still get over 5,000,000cEM/sec total with both cores running ~2.2GHz. I'm happy with that. :)

If I can't get the video driver to install, I'm thinking of sending the board back to NewEgg and ordering another one. There is another DDR1 board that people have had luck with, but I may just go for a decent DDR2 one and bite the bullet.

I got spoiled with the ECS K7S5A I think. That board kicked major butt for how little it cost back in the day. This ECS board isn't anything to write home about, that's for sure.

[Bok]

Dasm,

unfortunately that's what I thought might be the case. Similar for me I'm kinda loathe to have to go DDR2 when I've got 25Gb of DDR or so :(

Bok

[Jeff]

Geeze... and here I was thinking my 8Gb was alot to "waste". :( Sucks considering the lack of real performance gain.

[Helix_Von_Smelix]

ASRock do a 775 conroe board. AGP, DDR, or DDR2 looks good:thumbs:

That done be the one. ;)

[Jeff]

Just ordered the AsRock to see if it's any better(it can NOT be worse!). ;)

Here's a decent review of it in case anyone is interested...
http://www.ocworkbench.com/2006/asrock/775Dual-VSTA/b1.htm

[CaptainMooseInc]

Why does it seem to me like the ASUS board would've been the better choice?

I like to stick with the Triple A for most of my parts.

Antec (case)
Asus (board)
AMD (proc)

Now if Corsair, Seagate, and nVidia could just change their name to names that start with A. :-p

[Jeff]

Read some negative things about the Asus and it seems like not many people recommend it. The ASRock at least has volt. mods done for it already and people seem to be pretty happy with it.

And hell... if the AsRock is as bad as the ECS, then maybe I'll give the Asus a try. I mean, it's only a 15% restocking fee away. :)

[Jeff]

Wow, that was quick shipping from NewEgg. ;)

This AsRock board is head and shoulders above the ECS. I'm running 290x8 right now right out of the box and I'm sure there's more left. Very nice thing is the memory will actually run in dual channel mode which has helped SoB get to ~7.2cEMs/sec right now(after only about 2 minutes of running). There are also tons of memory settings in the BIOS and even some voltage adjustments.
:woot:
I'm looking forward to playing with this combination over the weekend.
:woot:

[edit]Up to ~7.4cEMs/sec now... :)

[Helix_Von_Smelix]

very cool

are you running DDR, or DDR2???

:thumbs: :cheers:

[Jeff]

Still runnig DDR1.

[Helix_Von_Smelix]

may have to get one. AS:rock: :rock: s

:lmao: :rotfl: :lmao:

[Jeff]

:rotfl:

The board has DDR1 & DDR2 slots and AGP & PCI-X & PCI slots. Pretty neat really. ;)

[Helix_Von_Smelix]

are you still running DDR or have you tried DDR2??

Did you get anything over 290x8??

:thumbs: :cheers:

[Jeff]

This board sucks %#$@ too. :(

290x8 wasn't stable even. And 280x8 was crashing after a couple days. I ended up loading Prime95, SuperPi, and PiFast and I could only get 272x8 stable on this board. I tried a few different sets of memory and it's just that the board sucks. There are a few voltage mods for this board, but people are only able to get ~290-300 stable with those even so it's not worth my time to dick with. :(

I've looked at DDR2 boards but those will require me to get memory and another PCI-E video card so I'm looking at ~$275 for those... which is just not worth it to me.

I think I'm going to go with a couple more AMD x2s(or Opterons) instead and recycle my DDR1 and AGP cards.

Anybody want an E6400 for cheap? Say $200 delivered? ;) (I'm going to return this motherboard too since it's soo horrible I can't see anyone using it... unless they didn't mind a 100% stock speed :eek:)


Oh well... I just had to give these Intel chips a try and they are very, very much worth the $$$, I just don't want to upgrade two *complete* rigs atm. ;)

[Helix_Von_Smelix]

I have this board with an E6600, working fine @ 290. you may be asking too much of an E6400. Lots of the O/C's are with different coolers etc

[Helix_Von_Smelix]

you may have cooked your memory. Put it all back to stock settings and memtest it. that is most likely thing. i have a 90mm fan sitting on top of the two mem sticks, blowing straight down.:cheers:

[cwhyl]

I'll give this ASRock board a try to, it's so dang cheap if you have AGP and DDR1 laying around. Three systems for the price of one "serious" Conroe :D

[Jeff]

The E6400 is known as a great overclocker and can go way, way higher than anything this little board can give it. ;) And as far as memory goes, I've tried 3 different sets of memory(6 sticks) and they all react the same way.

Guys, this board sucks. 290 sucks, 300 sucks, 310 sucks. The $109 Biostar Tforce 965 on NewEgg.com will go over 500. I just wish I had some DDR2 sticks around. I may still bite the bullet and do a complete makeover, but I'm not sure I want to spend the money. ;)

[Helix_Von_Smelix]

well if you want to go that far with the chip, you got the wrong board!!

Heard good things about the Abit AW9D-MAX ... I think it the ninja sythe cooler that works well, or go the whole hog and go for TITAN coolers!!!!


cash money!!!!!!!!
