Thermal Trottling

[idekius]

Sta je Thermal Trottling opcija u biosu i cemu sluzi? Podrazumevana opcija je na 50%.

Vrlo lepo za P4, ali covek nije naveo koji CPU ima, a kod AMD-a to nesto kao i ne sljaka

E pa ako ti radi obavezno stavi post, jer jos nisam video da sljaka. Kod tvoje ploce bi trebalo na 50C da se ukljucuje Thermal Throttling. Ako ostavis na tih 50% i procesor ti se dobro zagreje trebalo bi da primetis vidnu razliku, tj. uspooooorice ti se komp. bas lepo

Ma kakvi, ta opcija je glupost... Radi, ali nicemu ne sluzi...

A cemu sluzi ona opcija (kod NF7-S, barem) - Spread Spectrum za magistrale?

eh,da...ni meni nikada nije bilo jasno sta je to spread spectrum??????
Jel neko zna da objasni????

A cemu sluzi ona opcija (kod NF7-S, barem) - Spread Spectrum za magistrale?

To postoji na mnogim plocama, a evo jednog opsirnog objasnjenja:

Spread Spectrum
Options : Enabled, Disabled, 0.25%, 0.5%, Smart Clock
When the motherboard's clock generator pulses, the extreme values (spikes) of the
pulses creates EMI (Electromagnetic Interference). The Spead Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. It does so by varying the frequency so that it doesn't
use any particular frequency for more than a moment. This reduces interference
problems with other electronics in the area.
However, while enabling Spread Spectrum decreases EMI, system stability and
performance may be slightly compromised. This may be especially true with timingcritical
devices like clock-sensitive SCSI devices.
Some BIOSes offer a Smart Clock option. Instead of modulating the frequency of the
pulses over time, Smart Clock turns off the AGP, PCI and SDRAM clock signals when
not in use. Thus, EMI can be reduced without compromising system stability. As a
bonus, using Smart Clock can also help reduce power consumption.
If you do not have any EMI problem, leave the setting at Disabled for optimal
system stability and performance. But if you are plagued by EMI, use the Smart
Clock setting if possible and settle for Enabled or one of the two other values if
Smart Clock is not available. The percentage values denote the amount of jitter
(variation) that the BIOS performs on the clock frequency. So, a lower value
(0.25%) is comparatively better for system stability while a higher value (0.5%) is
better for EMI reduction.
Remember to disable Spread Spectrum if you are overclocking because even a
0.25% jitter can introduce a temporary boost in clockspeed of 25MHz (with a 1GHz
CPU) which may just cause your overclocked processor to lock up. Or at least use
the Smart Clock setting as that doesn't involve any modulation of the frequency.

Znaci, ostavljam na disabled... Ko bre da mi ugrozi overclocking?

Spread Spectrum ukljucis kada se procesor "gadja" sa nekim spoljnim uredjajem. U mom slucaju je od koristi kada odnesem racunar u studio i tamo dodje do zujanja. Onda lepo ukljucis spread spectrum i zujanje nestane zato sto racunar radi na promenljivoj brzini. +- 5% npr...

A na koliko treba da se stavi da bi bilo ukljuceno??
Da li mi zbog toga mozda zuji graficka pri skrolovanju? Ili kada je neka animacija?


POZ cheers

 

[idekius]

Ne... Zvucna kartica pri skrolovanju ti skrguce zbog loseg drivera.

Ne mora da znači da ćeš imati slabiji o/c. Meni je jedan 486/25 MHz pristajao da stabilno radi na 40MHz samo uz uključen spread spectrum. Doduše, postoje "manje" razlike u čipsetovima i samim procesorima između mog i tvog slučaja .
