whats the point of buying a P4 with a BUS speed of: 800 MHz?

I said this towards the very beginning... hehe

You are kidding me right? So how am I treading on "VERY THIN ice" Mr. 116 post member? Please enlighten me with your knowledge.

he was just stating his opinion, 2043. now be a good boy and fetch me my slippers.

First off, post count != everything. I've been a member since 1999 and am a recent refugee from the [ H], where I posted primarily. So don't get started in a "My intarweb pen0s is bigger than yu0rs!" match, it's really a waste of time.

Second, it's generally not considered good practice when referring to computers to assume that double of something = double performance (like the dual CPU analogy I used). Yes, both offer theoretically the same bandwidth, but there are differences (latency, etc). That's the point I was trying to make.

Dude, you're not helping your case when you use the Hardocp symbol which is the same as "highlight" and then the rest of your message along with your sig is highlighted...

 

[RyanVM]

hence the edit

Like I said, I don't post here often. Not used to anything but vBull

Can you then please tell me where I stated that double the bandwidth equals double the performance? I'd really like to know. If I remember correctly it went something like this:

P4 800MHz FSB CPU is paired with TWO 400MHz DDR stick for a total of.....Dual channel 400MHz=800MHz. Easy math class.

Did I say dual channel equates to double the performance? I didn't think so. Now beat it!

 

[RyanVM]

Dude, chill out...don't you think you're taking things a tad personally?

Secondly, Dual Channel 400Mhz != 800Mhz. That's the point I was trying to make.

I'm sorry if you took what I said personally, but that wasn't the intent.

That is MR. 2045 to you buddy!

 

[TROGDORdBURNINATOR]

by the same token you could argue that a double pumped FSB doesn't offer double the performance of a regular FSB. Or that a quad pumped doesn't offer quadruple the performance.
So, how does dual channel not equaling double the performance affect the fact that dual DDR400 can feed a 200QDR FSB better than any other solution and that it does offer performance increases?

 

[RyanVM]

I'm not arguing that in the least!

I was making a semantics argument, saying that it's not good form to equate dual channel 400Mhz to 800Mhz. It sounds like something a Worst Buy salesperson would tell one of their customers when selling a system.

There's no doubt that Dual Channel DDR400 is the best setup for a P4 system!

 

[mechBgon]

I don't think vaporize meant to post flamebait. It seems like a logical question from someone who's just getting up to speed on the topic of CPUs, chipsets and memory. Kudos to those who gave informative answers

me too. i think it read it wrong =D

 

[Daovonnaex]

I'm going to settle this with this little equation.

4 * 200MHz = 2 (2 * 200MHz) = 800MHz

 

[Spikesoldier]

single channel ddr @ 400mhz would be faster than dual channel ddr @ 200mhz due to latency reason.

until we have ddr @ 400mhz (800mhz effective), then we will have to use our boards with dual channel memory bus to acheive the bandwidth nessesary to feed that 800mhz bus p4.

Thank you - that's what I've been trying to say all along!

And since postcount is so important around here, hopefully people will at least listen to you...

 

[zephyrprime]

Dual channel of course. But even if there wasn't dual channel, a performance increase can still be attained because a big portion of the intial latency in reading ram is actually from the chipset.

WOW, 40 replies! I didnt want to drag this thread this long but thanks for the replies. It was fun reading all of them. I think I even learned something too. Well i was thinking about buying this setup from newegg this week:
---------------------------------------------------------------------------------------------------
Pentium 4 / 2.66 BGHz Northwood FSB 533MHz
ABIT IS7, Intel 865PE chipset
2X512MB 400MHz DDR PC3200

but since most of you want 2.4C 800 FSB, i am thinking of changing my mind to:

Pentium 4 / 2.4 CGHz Northwood FSB 800MHz
ABIT IS7, Intel 865PE chipset
2X512MB 400MHz DDR PC3200
---------------------------------------------------------------------------------------------------
I am not sure about getting ABIT IC7 because all the reviews at newegg post that it has problems and that you have to flash the bios. The 865PE also seems to have the same features as 875P.

The 2.4C is 40 dollars more than 2.66B but if it will give me a better performance than I am for it. what do you guys think?

 

[Wingznut]

Get the 'c'!

 

[Viper96720]

Don't matter what board you get pretty much all first versions need a bios flash sooner or later

 

[Dennis Travis]

Sunday afternoon I put a system together for a close friend, Asus P4P800, P4c 3.0Ghz 800Mhz Bus, 1Gig Dual Channel DDR (2x512Meg Sticks) 200Gig Maxtor with 8Megs Cache, new Gforce, 475 watt PS and so on. VERY FAST system. I was VERY impressed and with the Asus board too. They all have really done a good job. So fast even I was amazed. Get the 800Mhz Bus P4!! You won't be sorry.


I told my friend he now needs a new SATA WD Raptor to finish off his new system!!

 

[Slammy1]

For some reason, the IC7 lists 2-USB 2.0 ports under outputs, but the IS7 does not on NewEgg's site. That's what lead me to decide on the Canterwood vs the Springdale. I think the newer boards will already have the newer BIOS, since these boards go pretty quick I think stock turns around quickly.

I read somewhere that the 800 MHz CPUs will only be $20 more than their 533 counterparts, so I thought price was a newness premium. If not, I'd make my purchase much sooner (like yesterday).

 

[narzy]

for everyone flaming this guy, He's probably learned from AMD biased friends and is now learning on his own trying to grasp when he can. we all learn somewhere. this is a good place to start...well atleast until the assholes come out from their holes in the ground and feel its ok to degrade another forum member to make themselves look good. what they don't relize is they loose all grasp of any dignaty they had, and any respect they may earn in the future. I'm not going to comment on the technology because its pretty well covered. vaporize don't let the asshats of these boards turn you away or get you down.

Dual channel 400MHz does not equal 800MHz effective. I am running 2 sticks of PC3200 RAM at 200MHz (400 effective). When I went from single to dual channel, average RAM speeds increased by about 200MB/sec according to Sisoft Sandra, out of nearly 3GB/sec total. Definitely nowhere near a 2x increase.

I think that point's been beaten to death already in this thread But thanks anyways

And vaporize, I want to apologize for my part of the flamefest that took place here. It was a thread hijack that I certainly wasn't intending to happen.

Anyways, I hope you're happy with whatever you end up putting together - I'm sure you'll be happy with it!
