Where are MOFSETS, and which is better to OC, FSB or Multiplier??

post #1 of 48

Where are MOF SETs ?
Which is better to over-clock FSB or multiplier? (or both?)

So I hear a lot of "Your mofsets are going to blow up speech", and go researching. First read wiki about the metal–oxide–semiconductor field-effect transistor, then read my mobo manual to find out where they or it is located.

So no joy... I'm guessing that perhaps some mobo's don't have heatsinks on them while others do that it's probably the FSB or Sideport or something.

Which brings me to another question I've heard some people simply up their multipliers when overclocking eg. from 16 up to 20-24, giving them around 3900Mhz or 4000Mhz.

While others lower the multiplier say down to 14 and up the FSB to say 250 giving them 4000Mhz. Which is better? or what are the pros and cons to both?

I've done quite a bit of reading how to overlock (read about 5 different guides), but these are some things that are not really discussed in any sense.

its mosfet

most are right behind the back panel ports


since your cpu is a be, just overclock via the multiplier (it wont change your ram/ht/fsb speeds)
go slow (1 - .5 at a time) and check your temps under load (prime95 for a few minutes)

make sure the cpu temp doesnt go over 60c

overclock with FSB is much better cuz you overclock your whole system cpu\
orthbridge\
am and not just bumping couple more Mhz to ur cpu
example a 3.4Ghz cpu with 2.8Ghz north bridge would be much faster then a 4Ghz cpu with 2Ghz northbridge

i personally think it is much better to OC using Multiplier since easier for you to detect any problem if the OC does not stable. After find your max clock then up the nb.

and the point ? the only thing can be unstable in OC via multiplier is CPU clock\\low voltage so u gonna hit a wall at 3.9Ghz or 4Ghz so what ? u still gotta find new safe spots when OCing the whole system since its very different , sometimes highter NB clock allows you to overclock higher and vise versa , making the multiplier OC research irrelevant

and what ram multiplier is for ? ofcourse u lower it before OCign with FSB
the only con OCing with FSB is u gotta do the research , be patient and use common logic , everything else are all pros

Yeah just wondering the difference, I actually read the How-to-wiki when researching last week, and it suggested lowering multiplier, then upping FSB until you find the roof. then dropping it down to stock and upping the multiplier till you find it's roof. Then after that it is extremely vague and simply says you play around with both after that and loosen memory latency if need be.

So pretty much all I did was up my leave my multiplier alone, and upped my FSB to 250. Which gives me 4ghz CPU, slightly higher ram. Ram simply went from 1333 to about 1666. It's 2000mhz ram, but I think I read somewhere about AMD boards not being able to process ram above 1333 or something anyway... I don't know.


EDIT: As for the MOS FETs, I believe they are covered by heatsink on this board.

FSB is going to affect your overall system bandwidth when addressing memory, with a by-product of getting into the NB being component bandwidth.

CPU X is going to affect your processing bandwidth while there may still some room for total system improvement to avoid potential choke points.

I use the term "bandwidth" very loosely in this sense.

Personally I like a combined approach, first starting with determining what the mobo will do through OC' the NB until a no post. Than reseting everything to stock, and hitting the FSB and ram clocks. Wash rinse repeat.

Now one knows what your mobo/ram will do, try working with the cpu multiplier and find your post no post limits.

These numbers in mind should begin to build a picture as to what your combination of equipment will yield. At that point working out the best combination for the best bench scores/G.Flops/Stability/Watt dissipation becomes a bit of an art for again your overclock.

As for the mosfet/phase question, unless you know your board is better than a 4+1, I would recommend (based on what I have seen) to avoid breaking 1.5v on the cpu, in lue of potential damage issues that could result. Hope this helps.
