CPU Termination a CPU Reference, k čemu to vlastně je?

[valvex]

Zdravím, u desky Gigabyte EG41MF - S2H je možnost mimo CPU Core napětí nastavit i CPU Termination a CPU Reference napětí.
Nikde jsem se nedočetl, k čemu tyhle napětí vlastně jsou a tedy jestli je při taktování s nimi taky potřeba hýbat.
Víte to někdo?

PS: procík je C2D E5200
zatím jede bez úpravy napětí na 3 GHz

copak to asi znamena... pri dosazeni CPU Termination se CPU pravdepodobne vypne , CPU Reference bude (referencni napeti? xD) napeti, jaky urcil vyrobce.
nikdy sem to nevidel, ale neni to dost jasny uz z prekladu?...

co to asi bude taky netušíš. V biosu je vidět CPU Core 1,225 V a Termination 1,2 V takže se při tomhle asi nevypne...

popis všech položek by měl být napsaný v manuálu k desce

tak nevim, jen sem tipoval
jestli ti to pomuze:

Cpu termination voltage:
FSB Termination voltage, which is the termination voltage of the host bus but, more importantly, also the bus supply voltage. Intel’s specifications allow voltage levels between 0.83 and 1.65 on the termination buffers, however, keep in mind that the voltage is the same as the bus supply voltage, which is limited to a maximum of 1.29 according to Intel’s specifications. We did find that increasing the FSB termination voltage caused the CPU temperature to increase, at least compared to the “Auto” setting. Consequently, also the CPU throttling kicked in earlier and, particularly in graphics applications, the system had a tendency to freeze, followed by ATI’s VPU recovery message blaming ATI’s drivers.

Keep in mind here that the only thing changed was the manual setting of the FSB termination voltage, while all other system parameters remained identical. On the other hand, the strange behavior of misreporting benchmark results could be completely eliminated, with the caveat that higher bus frequencies required higher termination … er, bus supply voltages. In so far, all of this makes sense now. The Prescott with its much better utilization of the bus puts more strain on the bus itself including the clock domains – which, therefore heat up faster and consequently, need more voltage. On the other hand, a higher bus supply voltage also causes the bus to run hotter and, in addition, may cause more passive power drain from the CPU- which consequently will run hotter and throttle earlier.

CPU PLL – stability, just stay within my guide for voltages and muck around those voltages. One of the voltages will yield stability.

CPU reference voltage – "The CPU Reference Voltage configures the CPU Vtt voltage via preset ratios"
Cpu Vtt is the fsb termination voltage and is also known as vfsb on other boards.

etc etc. All comes back to stability. Like i said, keep within my guide voltages and you will live happily ever after. My guide was more along the lines of : 'keep within these voltages and your cpu won't burn'

Óóó, pánové díky, už je to jasnější.
PS: v manuálu k desce to rozepsané vůbec nebylo....
