New Mobo&CPU; Considering P9 805 for Overclocking.

I need to replace my aging P4 3GHz Northwood so I can fully appreciate the EVGA 7900GTX card I'm getting through their Step-Up program. This means I'll be needing a new Mobo, Cpu and Ram - everything else I should be able to carry over from my old computer. This system will primarily be for gaming, but I do do a lot of work with level editors, compilers, file compressing and converters.

After looking around I though that a Athlon 64X2 4200+ would be the best deal, but then I came across this interesting article on Tom's: A 4.1 GHz Dual Core at $130 - Can it be True?

Apparently, the rather inexpensive PentiumD 805 can be overclocked to 4.1 GHz, a very impressive feat which knocks down previous overclocking champions and even stands up well against much pricier, newer cpus. Now I'm thinking I may just try to save some money and get a PentiumD instead, and just overclock it to somewhere around 4GHz.

What I want to know is if anyone here has had experience with this particular chip, and if so what kind of cooling, mobo, ram would work best for overclocking. I've never done any OCing before, so I plan on being as prepared as possible.

I've done some looking around and here's what I've found that looks good for such a goal;

The Cpu itself, obviously:
Intel Pentium D 805 2.66 $190.99

Mobo:
Asus P5GD2-X Intel Socket 775 ATX Motherboard $130.99

Ram:
(Here's where I need help, I've never OC'ed a system before so I'm not sure what memory to get, I'll definitively need 2GB at least)

Air Cooling:Zalman CNPS9500 $88.99.
OR
Water Cooling (Likely needed at higher speeds)
Again, I'm not sure as I haven't investigated much into these, perhaps a Kingwin Liquid Arctic Cooler $114.99

Let's see that's $436 for a cpu, mb, cooling but no ram, pretty good compared to the $495 I'd need for the X2-4200+ alone.

Well first bit of advice is to order it from New egg (I like Tiger myself but this time newegg is 65$ cheaper....)

Also get some good DDR2 ram wich depends on how much your willing to spend. I have been looking at the 2GB kits of Patriot myself the price seems pretty good and reviews say its good. With RAM the same advice is true for any type get the fastest you can afford in the amount you want. In this case 2GB :)

You act like 4.1ghz is a whole lot for P'D. in reality, that is not the case. Get a 930 C1 stepping P'D and with proper air cooling 4.7 is very realistic. Using water cooling like with the 805 at 4.1, you could probably get 5 or more ghz. By the way dude, that motherboard you chose will not even run an Intel dual core/65nm chip. You need to have the 945, 955, or 975 chipset (or an Nvidia NForce chip) to run dual core. I understand you are in Canada, but I'll link you with some good overclocking 775 boards from Newegg.

Hope this helps. There's also a gigabyte SLI board called the Royale you might want to look at.

:cry:  Newegg doesn't deliver to Canada. Your best bet is NCIX.

You can get the 805D there for $150. Don't order from tigerdirect, unless

you like messing around with mail-in-rebates. GL :)

OMG 4.7Ghz ??? Thats fast.... Now I feel bad my poor old 805D is only running at 3.6Ghz :(  Thats over a full Ghz faster then me !!! lol (not to mention thats probably on a much much much faster FSB) ahhh well mines good enough for now and in a few months maybe Conroe will save me :)

yeah i know, the hype surrounding the 805 isn't well deserved considering a far superior chip is only $70 more

Ahh its ok I knew it was temporary anyway I already knew about Conroe but I wanted to do a few things on dual core for the cheapest I could get :)  (Learning about processor affinties in school got the best of me so I wanted to see what the fuss was about lol)

Actually, the 805D is[/is] a 775 socket chip and from what I've read, is still 90nm, so that mobo should work fine with it.

This is the processor right? Intel Pentium D 930 3GHZ LGA775 2X2MB 800FSB. Strangely it doesn't say it's dual core, yet I'm pretty sure all the 900's are.

Do you mean I can get 5Ghz with watercooling with the 930 or the 805? If so, that pretty attractive, even though it's $100 more-but it does OC better.

805 [$171]
2.66Ghz->4.1 (+%153)

930 [$264]
3Ghz ->5 (+%166)

Why link me 775 boards when you claim I need 945+'s? :?

775 is the socket number, 945/955/975 is the name of the northbridge. The chip you selected is the correct one. However, I am 100% sure that northbridge 915 motherboard you selected will not post a dual core chip.

Yeah, you're right, don't know why I was thinking that - too tired I guess :p .

I may just wait for the Conroe and AM2 processors to come out and see how they perform and are priced. Until I recieve my new GPU I'm in no hurry to start building a new system.

Current releases of Intel 975x boards support Conroe, FYI. 975 is way expensive though, so it's probably best to wait for a high-end 965 budget board.
