i have been running 10 x 220 for 2 months ......burned in and stable. my brother just told me that it was fruitless to reach for this high of a bus because the nforce2 controller will only hit 400 therefore i am only stressing my hole board for no reason. ....is this true?

If it's running at 220, then the chipset is taking advantage of the speed. Smack your brother for not having common sense.

he must be assuming that the board can only take 400Mhz as max,
but still if it wasn't supported, the computer would not have been stable like you said,

he needs to do more research on overclocking.

 

[Acanthus]

I once had someone tell me that overclocking a 2.4C to 3.5ghz was artificial and it only ran like a 2450. Then we ran bechmarks and timedemos and laughter and mockery ensued.

I think ur brother was talking about OC'n the Ram at over 400 fsb even though the CPU can do it. Everyone knows that overclocking Ram and CPU inhances the performance of the mobo to a point. You want to balance the Ram and CPU for optimal performance. I think what he meant is when u OC the FSB beyond 220(440) it hits a wall with the chipset and the video card and the HDD's are being stressed beyond what they r able to handle and not able to function fast enuff to make much of any difference(unless u do have top=end video and SCSI HDD's) those speeds because with the 400 (200DDR) the FSB tops out at 3200 anyways (which is the speed of ur RAM and faster than anything else on ur system including the CPU) and can not go beyond that number(and this is true only for AMD32bit not Intel). Sooo, I think what he was saying is that u r stressing the mobo just to pump up the CPU with no added performance which is fine but not practicle for internet browing, e mail and chats (forums included).......

I think what he meant is when u OC the FSB beyond 210(420) the video card and the HDD's are being stressed beyond what they r prolly not designed for(unless u do have top=end video and SCSI HDD's) those speeds because with the 400 (200DDR) the FSB tops out at 3200 anyways (which is the speed of ur RAM) and can not go beyond that number(and this is true only for AMD32bit not Intel).

if i wanted to limit my time to email and "internet chat" i would have stuck with my packard bell 233!

What did he say?

 

[DAPUNISHER]

What he said is "Hi, i r n00b"

He's under the impression there is not only the lack of a PCI/AGP lock on the board but that due to the max bandwidth usage of the Barton that once it's saturated there no reason for the additional bandwidth. To a small degree the he's correct about the bandwidth in that it is the law of diminishing returns after a certain point. Then finally he's laboring under the delusion that the owner is cranking all these speeds up and not using it to it's full potential, so the extra speed is useless, and to that I can't answer because I don't know if he's using a fast vid card and doing some serious gaming, or media encoding, or crunching DC projects, ect, that will take whatever you can give them

 

[fleflikr]

gameing and media encoding have been a priority for me lately. i would say i have a good vcard (nvidia 5200fx) but by far not the best. since gameing also heavily taxes system ram i thought the extra bandwidth would help. (looks and feels smoother)
however the real reason i migrated to these settings is because the system benches better and stays cooler while staying very stable, more so than a 10.5 x 210 or 11 x 200 setting.
i was very surprised my system was able to hit my current settings let alone bench and burn stable and cooler.
i appreciate very much the response i have gotten from senior members in this oc forum. if the general feeling is that i may be running too close to the edge then by all means i will pull back.

thanks

 

[DAPUNISHER]

Pull back? Hell no son! Full speed ahead and damned the Torpedos! :beer: That's an awesome setup, enjoy it :light:

 

[valky]

That lock is adjustable on my Abit but I dont know about yours if you are refering to the Ram ....

I think your brother is talking about the limits of the AMD mobo's (200DDR NVidia) no matter what hardware or software you use in it as the maximum bandwidth is 3200 at the FSB no matter what- meaning the slower hardware and even software (such as windows when playing games) is the bottle necks and not really obtainable, no matter what you are running and yes this is the bandwidth limitation for AMD mobo's from the chipset.............

It doesnt matter what CPU we are talking about here because it is universal to say(with AMD) that they can be OC'd and with great results. I think his brothers point there was involving the use of multis and FSB with the CPU and Ram timings that a limit is there in the chipset over a point (440)with the bandwidth for the FSB and its better, performancewise, to lower the multi and incress the FSBup to 400 and over to 420 and beyond that point raising the multi to put the added stress on the CPU makes it faster and the tras needs to be doubled at dual channel which leaves the rest of the system optimal......... :beer:

 

[DAPUNISHER]

You're his brother aren't ya Valky

 

[fleflikr]

BINGO! .........

 

[dnuggett]

Valky.....

Use Google, read up a bit and come back when you get some real info to help others with. Of just relax a little and quit digging a hole. Take some time to read the multitude of posts here and get a feel for what is going on.

Ummm.......... I dont see anything new in this discussion as its rather old hat talking about overclocking CPU's and not understanding what else is happening, such as the bottle necks and their causes, but if you would like some links to verify what I am saying, u could look into the back archives from the last 2 years topics in different forums. I see you can use google so you can do that for urself- and now the rabbit is outta the hat- you can see why I even bothered with this discussion in the first place was because I never did say to my brother "fruitless", thats his word. My point was and still is that thinking the N Vidia chipset is a single controller is something you might learn on google, so..... look real hard....

Yet again, what? Nvidia chipset is a single controller? What, exactly, do you mean?

He has no idea what hes talking about, but thinks he does, my favorite type of person to deliver support to.

 

[Soulkeeper]

some people can run over 400 or even 440
in my experience tho with 3 nforce2 boards i found this difficult
but there are many factors to take into consideration

if you system is running stable at that speed and configuration even under heavy stress then you are good
but if the systems starts locking up or rebooting on a hot day then you might need to bump it down 10mhz or so

that is a respectable speed you got there

 

[fleflikr]

its winter now and we keep the room heated in the upper 60s. im sure this is a factor. the proof in the puddin will be during the summer months.
ive spent about 2 months playin with this thing and cant help but think that all the burnins have somehow helped this computer find its own sweat spot.
the pinacle piece of this whole system i feel is the thermalright 900a hsf.
i opted for a large 92mm panflo fan that not only covers the entire heatsink, but also extends out to blow air directly on the northbridge and ram as well. temps are generaly in the low forties. prime 95 stays put at 50 all day long.
once again, thank you kindly

 

[Jeff7181]

I think trying to convince valky that he's misinformed is futile... so if everyone would just ignore the "information" he provides, it would be in your best interest

 

[valky]

Benchmarks using SuperPi - 1M

XP2100+ default - 1733MHz(13x133) = 62s

1754MHz (10.5x166) = 58s

------------------------
1837MHz (11x166) - 56s
1704MHz (8.5x200) = 56s - 400FSB v. 333 FSB = +133MHz
------------------------

1921MHz (11.5x166) - 55s

------------------------
2005MHz (12x166) - 53s
1837Mhz (216x8.5) - 53s - 432FSB v. 333FSB = +168MHz
------------------------

2088MHz (12.5x166) - 51s
2105MHz (10.5x200) - 49s
2170MHz (11x197) - 48s

------------------------
2205MHz (11x200) - 47s
2172MHz (10x217) - 47s - 434FSB v. 400FSB = +33MHz
------------------------

2269MHz (10.5x216) - 46s

This is a limited set of tests based on a single benchmark, but it looks like going from a 333MHz FSB to a 400MHz FSB gives the same increase in performance as a 133MHZ increase in CPU core speed.

Going from a 400MHz FSB to a 432/434MHz FSB yields a rather dissapointing increase in speed equivalent to a 33MHz increase in CPU core speed.

It looks like FSB's higher than 400MHz may not be all that important after all. This would negate the NForce2's principal advantage over the KT600. I cannot run higher FSB's than those used in this test, but I would assume that higher FSB's would produce diminishing returns.

Any thoughts gentlemen?........
