Interesting how this thread became a pin mod thread. Going back to the original question about FSB speed, how much of a difference is there between 400mhz and 533? Is it actually a noticeable difference? A lot of these numeric increases don't really end up doing too much since so much depends on design.

Just a general note: anything which speeds up access to main RAM is a good thing (tm). That's why caches were designed--to make up for slow main memory (and hard drives). I can't offhand show benchmark differences between, say, the 400 MHz and 533 MHz fsb versions of the 1.6 GHz Pentium M...anyone have a link?

My test results from another thread are below:

Partial Results:
Kingston 6000A 512MB 533FSB 4200 chips were used.

single-channel ( 1 533 4200 512MB chip):
Memory read: 3292
Memory Write: 746
Latency: 109.2

dual channel (2 533 4200 512MB chips):
Memory read: 3313
Memory Write: 818
Latency: 103.7

Everest correctly reports no dual channel when there is one chip only, and correctly reports dual channel when both chips are present.

Now, tests vs. real-life performance:
My top desktop system has 3.42Ghz P4 ( 2.4 overclocked of course) and 2 dual channel Geil Golden Dragon 800FSB 512MB RAM. Dual channel is very much in action on that machine, HT is on so there are two logical CPU's which software that aware of multi-cpu machines can use. Hard drive is Seagate 160GB 7200 RPM.

.. and as I've mentioned in my other post, MainConcepts MPEG2 encoding of the 19 min 54 sec AVI clip to MPEG2 took 38 min 03 sec on the desktop PC and just 32 min on my 6000D.

6000D is an excellent laptop, at least for my purposes.

Cheers.

In fact after undervolting to 1.21 it producess less heat than factory-set 1.6Ghz w / 1.34 V.
But not before undervolting. Taking a generic 1.6 725 and pin-modding it to 2.13, there is going to be more power consumption and more heat produced unless you take another step to reduce it.

Anyhow. MaineCoon, do your test results mean that the extra FSB doesn't make a huge difference? (Or is it opposite?)

It does NOT make a huge difference as you can experience on the desktop with 800FSB single vs dual channel.

However, every single bit helps

Given the price difference between 400 and 533 minimal, it is worth to get 533 for 6000D. IMHO.

Well considering the price diff between a 1.6 400 and 2.0 533 is anywhere between $231 to $350 at dell (depending on if the moons are aligned, what day it is, and what side of the bed Michael Dell wakes up on ), this mod IS nice for those who want to venture into the territory

I meant price for RAM 400FSB vs 533FSB. It is negligible for 1GB and sometimes you can get 533FSB cheaper than 400FSB.

Oh yeah, you have to have 533 CPU.

But it's not even about money. It is about immense pleasure of coping with hardware and getting so much more for so much less.

But yes, it is a higher FSB that causes it.
the 1.6 400 has a multiplier of 16, 16 x 100 = 1600

the 1.6 533 has a multiplier of 12, 12 x 133 = ~1600

when you change a 400 to a 533 with pin mod it keeps the 16 multiplier and you get 16 x 133 = ~2100

I wasn't defensive. It was a joke.

You can work on my computer education. I can work on your sense of humor.

You are boring and offensive as hell. Hopefully we'll never see each other again on another threads.

i corrected your incorrect technical info

then you called me daddy as if I were some sort of authority figure because I corrected the incorrect info, not funny and immature

i suggested you need not get defensive

you suggested I need to work on my sense of humor and in return I suggested it might be you who needed to tweak your sense of humor, which was more funny than your daddy remark

then you say I am boring and offensive?

if I am boring then why reply and at what point did I get offensive?

how about now...

you are a moronic twit who wouldnt pass the test if there were one to post on these boards, your user name is a fvckin pussy cat and you have a bad sense of humor and thin skin to boot

edit: plus my 1.7 to 2.26 pin mod is faster than yours nah nah na-nah nah

Sorry I called him daddy. We have a lot of men like him here in SF in one of the famous districts of our famous city. They all are childless

Here is another "nice" post by this clown, strictly_biz where he addresses someone else:
"have you considered a xanax prozac combo or maybe a paxil zoloft cocktail". Looks like he knows what he is talking about.
