I was reading this article this morning and like everyone else, I'm very interested.

I want to use the exact same parts that were used but I'm not 100% on the RAM & V-Card.

Has anyone else tried this yet, or is this something I should wait till more people try it?

This is what I was looking at getting.

(might look at W.C. if it works up to 4.0Ghz)

Should all of this work or is there other stuff I need to consider like the CAST# SL8ZH or other stuff?

Thanks

no overclock has a 100% successfull rate, while i u may not get to 4.0ghz you will probally at least get close (ie 3.7-3.9ghz) as long as you case has good air circulation and what not. Hell The article basicly has an instruction manual on what voltage and what not lol!
 
FYI: That motherboard supports Crossfire, not SLI. Don't think about doubling up on that 7800gtx, you won't be able to.

Well technicly you can't. I am just waiting for the Chinese guy who got 2 7600GTs running in SLI on a DFI CFX3200 board to post how he did it so I can. But your very right, I wouldn't advise getting a CF board with NV card, and if you really want to go that route buy a 7900GT they are abotu $300 and as fast as a 7800GTX stock and faster when OCd.
 
first of all

4.0ghz on this thing is unreasonable

this is again one of THG biased articles.. it's comparin an extremely overcocked chip with its' settings to the extremem max almos at the point of failing

to stock high end CPU's.... and saying it's a better CPU.

GET REAL. how much is intel paying you for this!!!!


however as for the SLI dealio. the lower NVIDIA cards can RUN in SLI mode without an SLI bridge on motherboards that have 2 8x PCI slots. they're not a full SLI and have a lower data transfer rate but it works. the 7600's are a good example of cards that easily can do this. and since they're not top of the line cards you're not goin to get top of the line out of them. however, you can run SLI with 7900GT's without the bridge, but it wont be so fast.

and why SLI 7600Gt's.. just get one 7900GTX and it'll work better in the long run
 
why is it so unreasonable.....they are not saying that its the best way to go...they are saying that this chip OC's like a MFer. And that was the point of the article. For some buying a chip for a $1000 is out of the question. Going this route, even if the same results are not achieved, saves alot of money. Even if you get it to 3.6 or 3.8 ghz.......for a $130 and its Dual core, I think its a good deal......so STFU
 
hell i am impressed

dont get me wrong...


but i'm very wary of anything oerclocked that much

i think a more beneficial test would be to see a CPU clocked this high, runnign for a few months glitch free...

I agree.

Paying $1000 for a chip that will be out dated by the time I save the money up is not an option. I'm not looking to push it to the extreme but to 3.6 or 3.8 ghz would be a good way to go.

Is there a better MOB that I should look at that will work with this an is nVidia. I will want to upgrade the v-card to A Quadro PCI Express SLI for the work I do, but need to save up for awhile.

I agree. But what is the worst that could happen if it only lased a year? You would still get your money out of it.

I was thinking about going with AMD X2 4400 but now I might be changing my mind.

Anyone else have any suggestions?

Do i need to post a CPU-z of my XP 1700+ JIUHB running @ 2.1Ghz on an old volcano 7 (not the better 7+ mind you) for nearly 3 years now? June will be 3 in fact...

In fact it only needs a vcore adjustment over stock of .025V to run stable 24/7/365.

2.2Ghz required .1V to .15V so I backed off. Wasnt worth it.

Some chips do th at, remember the celeron 300a? If a process is pretty mature then its nothing. Think about it, the old northwood got as high as 3.4Ghz from the factory, that was TWO full processes ago. This isnt that hard to believe. In fact, I was contemplating a very similar build myself vs the Opteron 170 I instead got. Kinda wish'd I'd gotten the 805d though. 3.8Ghz would be a nice number...

Heck Toms article is just trying to make one point. you can get 150.00 CPU and can OC it so it gets close to the same performance of the $1000+ CPU's like the FX or the extreme. I don't know how this is Bias i did not hear any negative info about AMD in that whole article. if you don't like the site don't come here simple as that.
 
(this isn't a response to anyone, I just hit reply at the end...)

First, I'm an AMD fan. Notice I said fan, and not fanatic. I don't seem to be impressed by this article quite the same way many of you have been. They didn't get past 4.0GHz until they went watercooling. If they had hit 4.0/4.1 with the aftermarket air cooler, that would be something. That said, its still pretty amazing that they hit 3.6 with nothing more then a mild voltage bump and an aftermarket air cooler. I don't think I would even try to hit 4+GHz with one of these, the heat/watercooling/energy consumption are complete turn offs. But the fact that they hit 3.6GHz and that required almost no effort IS something that people should notice. Granted it doesn't have the massive amounts of L2 cache that other dual core CPUs have, I believe the better price/performance ratio helps make up for that.
 
I would probably OC it a little, especially when you don't need to increase the voltage. But the real performance gains come after that point. Oh well...

god you are a tool. they're saying it's great for overclocking price vs performance. intel is paying toms hardware less than amd is paying you to totally misread an article and post things about it that arn't true. the article was just about the intel cpu had nothing to do with amd.
 
Can't speak to the overclockability of the D805 yet, as I just received the parts in a UPS shipment. Here's what I can tell you though:

Parts List:
Asus P5WD2-UAYZ Motherboard (Intel 955x+ICH7R)
OCZ 2GB DDR2 Kit PC2-6400 (5-5-5-12)
Pentium D 805 B0 SL8ZH
Thermaltake BigTyphoon

I'll be starting the build-up tonight, and should have everything setup and OC'd by Monday or Tuesday (stability testing takes soooo long). I'll post back with how far I can get it to go on air.

And you are a tool as well reacting like that. It's a message for the people who allready own watercooling and the equipment for it. Orelse you be better of buying a amd x2 instead of buying extreme cooling + pentium 805 D. hehe
ching ching. 😀 I think this says enough unless somebody does not agree 😀
 
Like others, I was impressed by the article. I was one of many who ran a celeron 360 at 100mhz. This sounds like the first example of a similar opportunity.

then near the end of the article I looked at the benchmarks...yes the 805 showed very well once oc'd...but how much better than my current AMD64x2 3800+....well on the chart a fair bit, but when I looked at the absolute difference in frame rates...I doubt I would notice the difference..

I guess you do things like this just to do it, really...not because you need so much speed for a given task. I probably won't....but its fun to consider.

While I'm a fan of the 805 for some OC'ing and low budget builds, I believe you would be better served by a 920/930 PD. This article shows how well they perform.
http://www.xbitlabs.com/articles/cpu/display/pentium-d-920-930.html

Keep in mind that these were B1 revision presler cores they used and that C1 revisions have since been released with allegedly better OC'ing potential. The prices will also continue to fall and Viiv may actually be desired down the road which you don't get with the 805. Don't forget the 2Mb L2 cache per core with the 9xx series as well and lower temps.

Don't get me wrong, I believe the 805 is a great bargain with obvious OC capabilities but if your willing to spend a little more for a C1 revision 920/930 you will have a CPU with staying power rather than a whim.
I will be buying a 930/940 once prices bottom out this summer/fall and of course, OC'ing the $hit out of it like my P4 630.
 
The point of the comment was not to say "hey go buy 7600 GTs and SLI them on a CF board" the point was to say it is possible to run SLI with a bridge on a CF board via driver hacks.

The RD580 just overclocks a little better than the Nforce chipset so when my Nforce mobo blew a capacitor I went for the RD580 knowing that it was possible to do SLI on a CF board, its just hard. The actual loss of FPS when not using the bridge on a x16 SLI chipset (not X32) is about 5fps fyi, not much but noticeable.

Intel isn't paying jack for this article, and I found it very interesting and well done. I particularly like the analysis of the change in power consumption they did. Everyone knows that OCing takes more power, but this shows you in absolute terms exactly how much extra power it will take to keep this chip running at 4Ghz+.

Since THG's point was to show the complete potential of this chip, stopping anything short of the brink of failure would have been bad reporting. They took it to the extreme and classified it by levels, ie when voltage bump became necessary, when the stock cooler failed, when the after market cooler failed, and when the proc just wouldn't go faster. That is a well done article.

The only thing I would liked to have seen is them pitting the Opty 165 against it. I realize that the Opty is more expensive, but it falls under the same general category as the D805. It is a chip that overclocks very well and consistently hits 2.6Ghz. It would be an interesting suppliment especially in terms of power consumption and gaming performance.

Props to THG. 😀

You are completly wrong, toms hardware isnt biased, if you read their conclusions on hardware testing of cpus and gpus. Intels overclock like monsters and its not at all outlandish getting that processor to 4.0 ghz and above, this is made easy with the 533 mhz FSB, because you dont get an FSB problem. Intels have always overclocked like monsters, I have a P4 overclocked from 2.4 ghz too 3.6 with stock voltage. I have another P1 which I overclocked from 133 mhz too 200 mhz... which is insane for a 9 year old processor(still runs to this day). The only processors which have dissapointed me when overclocking are amds.
 
Not Too Surprised!

I used to have a P4 S478 3.2Ghz Processor, on a CoolerMaster JET4 Copper Cooler.

Before I purchased the X800PRO on my las system. I had a GeForce4 Ti PNY the old classic one. and I managed to OC, Boot & Test my system on 4.0Ghz

altho, when I got the X800PRO, I couldn't get past 3.73Ghz, sometimes components can be the problem, sometimes they're a match, sometimes, they won't even OC 5% It's just Luck & Quality I guess.

My Actual System is a AMD X2 3800+ 2.0Ghz, I have it OC at 2.6Ghz "5000+" (Or So Everest Reads ^_^) that's a 30% Increase with some decent cooling fans and Copper Heatsinks...
