Got a question on FSB speeds. Well.. tons of questions, but....

P4 1.5GHz running @ 1.64.. yeah, warmed it just a bit. (rest of my specs are up there^)The P4 can do 400MHz FSB, and the MB supports the same. I ran Intels' indentifier and it shows that 400MHz was expected but was actually 436MHz, for what that is worth. Yet when I ran Memtest, mem came up as ok, yet it clocks my bus @ 109MHz. I've been reading info on it (probably too much) and have got meself

!!

So which is the real deal? She kinda lags sometimes, which I'm sure is due to lack of mem, but for the most part runs ok. Just want to get as much as I can out of her until I can put the $$ in more mem. I assume (you know what that does)

memory affects that bus, but a little info would be appreciated!
Oh, and temp wise, even under full load runs around 43C degrees max. From what the specs say, that's in an ok range.

Suggestions?

TY in advance!

if memory serves correctly, and you may want to read up on this, the fsb can be multiplied by the processor to actually perform at a higher rate than what it is running at; this is not overclocking, this is more standard operating procedure. If you look at the fsb by itself, it will generally give you a lower number than if you look at it as part of the system.

Mind you, that's from the ol' A+ days, and that was a bit ago, so I could be slightly off in that regard....but I think I'm pretty close.

Sir Trews

Ok... I can buy that... but the question now becomes... THAT much slower? That seems like losing 300MHz that could be helping this thing along.... I dunno.. back to the 'ol books I suppose. Never a time to stop learning, right?

I had looked around in the forum for info on this, but nothing seemed to pertain, yet I see that some have had their systems checked. How 'bout a link or three or something else I can use to verify if I really AM just a babbling fool!

THanks for the looksee valis!

check this one out:

FSB overclocking is the most common method of overclocking, as almost every
CPU allows you to adjust this value. As mentioned in the section above, the Intel
Core 2 Extreme X6800 is the only processor model that you can increase the
multiplier value. This means that the only way to overclock a lower Core 2 Duo
model’s clock frequency is through the FSB. The following procedure explains how
to do this:
1. Enter the BIOS by restarting your computer and pressing DEL during POST.
2. Next navigate to Advanced Chipset Features „ FSB & Memory Config
3. Go to the FSB – Memory Clock Mode and you see three options:
a) Auto – this is the default setting to let the BIOS determine the FSB and
MEM clock values
b) Linked – this mode allows you to change only the FSB bus speed; the
MEM bus speed adjusts accordingly.
c) Unlinked – this mode allows you to independently change the FSB and
MEM bus speeds.

Well.. I tried what you said and my BIOS doesn't give me the option to set the FSB manually. Once you had said that, I really thought that it did, but alas!! No such luck.

Ah well

there's a couple of pieces of software out there (the name escapes me) which you can use to o/c your FSB from windows, they are similar to software like uguru by abit.

However it only works on certain boards and you need some details about motherboard parts to be able to use it. Also if u feck it up, consider your XP install fecked and start again.

Good luck
