HELP! Intel Pentium D 805 Versus P4 660... need adivce!

post #1 of 15
Thread Starter 
alright... im still kinda new to this overclocking thing cuz im running on an intel board which doesnt allow modding the fsb and all that #s that u guys play with... so with that in mind...

i am currently running a P4 3.6ghz with HT... i think its the P4 660... running on the intel 945psn...

and the question is:

would it be better if i ran an intel pentium D 805 2.66ghz along with a Gigabyte 945P

i noticed that the Pentium D doesnt have that intel enhanced speedstep thingy... dunno what it is... and also that the pentium D has a FSB of 533... instead of 800 compared to the P4

so which one would be a better/faster config... speaking in terms of overclocking it to the fastest yet safest point...

o yeh i have 2x512MB of DDR2 533 ram... if that helps

thanks... im very newb


btw any links to faqs or guides on how to overclock the comp? hah thanks

Now im no massive overclocker. However remember your decision shouldnt just be based on overclocking ability. It all depends on what kind of PC user you are. The Pentium D 805 is a Dual core CPU allowing for more multitasking at a more efficient level. The 805 is also a great overclocker so you wont be dissapointed with the CPU regarding that. Your current CPU is a nice one as it features 64bit addressing thus allows for the running of a 64bit OS platform and Apps. However Dual core is a heavy advantage in alot of areas.

Personally i would go for the 805 due to it being dual core and it being a great overclocker. The motherboard shown is ok however im not sure on its ability to overclock and you may benefit abit more from a motherboard in the Asus range.

The 805 overclocks like there is no tomorrow!!!
Get one, and a good board (p5B for e.g.) and a BT and you're good to go.
About the speed, i think that even a week dual core cpu would beat a fast single core cpu, because when you're not multitasking , it uses both cores in the same application....

Also if you wish to know what Speedstep is here you go :

Quote:
A technique used by Intel in its microprocessors for portable computers in order to save battery power. It allows the processor to operate at its fastest clock speed when the computer is plugged into mains power, but forces it to cut back to a slower speed (using less watts) when running on the battery alone.

The 805 may overclock like there's no tomorrow but it'll take a hell of a lot to get to 3.60ghz like the P4-660 and the P4-660 did 4.20ghz for me easy, I don't think an 805 can do that.

Speed wise, the P4-660 is a much better CPU, but! you have to use a nice board that will overclock it to 4.20ghz. BTW, stock cooling doesn't help much for overclocking, you'd need something like a Thermaltake Big Typhoon to achive that speed.

Well, I've overclocked my 805 to 3.66 with no problems - and am running stable at 3.5.

I must agree that stock cooling is rubbish - I use a Zalman as per my signature..

Good luck!

if you have to spend money on it and you've already got hyperthreading, then i dont think its worth it. just my opinion though.

Hyperthreading is just the production of a Virtual core and splits the CPU cycles in half. Having a 2nd physical core would serve you much better.

hmmmm thanks for all the replys... i have a big typhoon already

but haha still cant decide what to do...

so theres really no sure choice in this one? haha

o yeh... as well as the FSB... its 533 compared to 800 on the P4... any idea what the differences might be? cuz i heard that since the its a dual core... the 533 will be 1066? iono i just heard that from somebody and im trippin over it cuz i have no idea if that means its better...

The 533 FSB will give you a lot more overclocking headroom, meaning much higher clocks over the 800 FSB CPU you have now.

Intel's FSB Speeds are "Quad-Pumped". This means that the effective FSB of a 800 FSB processor is 200, which is what appears in BIOS. So your the 533 FSB of the 805D will be 133MHz.

Generally, a lower FSB means a higher multiplier which allows for a much higher overclock than a higher FSB and a low multiplier, because the northbridge will not have to do as much work with a low FSB/high multi than a high FSB/low multi combo.
