BIOS FSB for Athlon 2500+ Barton??

hvor meget tillader den dig? :)

Højst 200

hmmm... så skulle jeg mene at det er sikkert at sætte fsb til 200 ;)

men, jeg vil dog alligevel råde dig til at lade være mm. du mangler extra performance.

okay så vil jeg lade være ;o), men hvad skal den så sættes til og hvordan ved jeg hvad den skal sættes til - er der nogle regler?

Normalt kan man kører et program inde fra bios (ved dog ikke hvilket bundkort du har) der kører en række tests og udfra resultaterne vurdere den de bedste settings for dig.

jo du ved... MSI K7N2 står øverst ;o) og den bruger bare "normal" awardBIOS CMOS... men det er mest fordi jeg vil vide hvorfor man sætter FSB'en til hvad man nu vælger og hvordan hænger det sammen med CPU'ens FSB på 333?

ok, men JEG kan ikke fortælle dig så meget mere end jeg har gjort.
Men en god regel at huske på er, at man ikke skal overclocke mm. man har brug for det.

Hmm okay, tak for hjælpen - mit spørgsmål finder jeg dog ikke besvaret og lader det stå åbent noget tid endnu... hvis du finder ud af noget, så kommer du bare tilbage og høster pointene! :o)

fandt dette,

The AthlonXP is available in two versions:

Athlon XP 2600+..... (333MHz FSB) 2.083GHz ..... 12.5 x 166
Athlon XP 2600+..... 2.13GHz ..... 16 x 133

Usually, with overclocking the best thing to do is, if you can, have the fastest RAM  you can -  it's usually the issue when it comes to overclocking.

The best results come from setting your FSB as high as possible, even if you lower your multiplier to get it.

For instance, the 333MHz version of your chip, although only marginally faster in it's total frequency, performs better than the 266MHz version because of it's increased FSB.

Generally speaking, the best way to overclock is as follows:

slowly increase your FSB in 1MHz increments, and run some benchmark (PCMark, 3dMark, SiSoft Sandra, etc.) to check initial stability.  If it is working stably, increase it again.  Do this until it becomes unstable or won't boot, then move back down to the last known good setting.

Personally, if you have a 333MHz version, and some PC3200 RAM I'd try clocking it at 11x200 (lower multiplier, but much higher clock speed) and check stability.  If it  boots stably, I'd try 11.5x200 and 12x200.  If you can get 12x200, you'll be running at 2400MHz, which is roughly a 25% increase in cpu frequency, with a 25% increase in FSB as well, for much better performance.

If you have the 266MHz version and some PC2700 (or faster) RAM I'd initially clock it at 12.5x166 and increase the multiplier if it's stable there.  If you can get it stable at 13x166 (2700+) or 13.5x166(2800+) then I'd also try increasing the FSB at that point until instability shows.

Remember as you overclock you may have to increase the VCore of your cpu.  Don't raise it too much, I personally didn't ever run mine past 1.85, but I've heard 2.0v is safe if you have very good cooling.  Raising the voltage of your cpu will also raise the temperature of it's internal die, so watch your temperatures closely.  Ensure you have a good quality cpu fan/heatsink, applied correctly with good quality thermal paste.  Ensure you also have a good quality power supply, and a quality case with good airflow.  A front fan mounted low drawing air in, and a rear fan mounted just below the power supply blowing out is a good way to improve cooling, and the fans are only $5 or so.

Anyway, in a nutshell, higher FSB gives you better performance than increased multiplier.  I have an old Tbird rev. b 1800+ that I run at 170x12.5 right now  (supposed to be 133x11.5).  Wcpuid thinks it's a 2600+ running at 2125MHz.  (not bad for a cpu that is only 1533MHz supposedly) and I don't currently have my voltage increased whatsoever.  It's wonderfully stable.

Totalt i orden du! Kan du give mig linket til det sted du fandt dette??
Du får hele baduljen af point for dette :o)

Tak for hjælpen - og venligst smæk linket op...
