Kodi kuwonjezera Raspberry Pi Pico 2 mpaka 873.5MHz kumakhudza chiyani?

Kuwonjezera Raspberry Pi Pico 2 mpaka 873.5MHz kumatanthauza kukankhira purosesa yake ya RP2350 kutali kwambiri ndi liwiro la wotchi ya 150MHz posintha masinthidwe a PLL ndikukweza mphamvu yamagetsi mpaka 3.05V - pamwamba pa 1.1V. Izi zimafuna masinthidwe amtundu wa firmware ndikulembetsa mwachindunji. Njirayi ndi yongoyesera mwachilengedwe, imachotsa chitsimikizo chilichonse, ndikuyika chiwopsezo cha kuwonongeka kosatha kwa chip chifukwa cha kusuntha kwamagetsi ndi kupsinjika kwamatenthedwe pamikhalidwe yoopsa ngati imeneyi.

Kodi kuyendetsa Pico 2 pa 3.05V core voltage ndikowopsa pa chip?

Inde — 3.05V core voltage ndi "mwankhanza" monyanyira ndi kapangidwe kake, popeza RP2350 idavotera pafupifupi 1.1V mwadzina ntchito yapakati. Kuchulukirachulukira kopitilira muyeso kumathandizira kwambiri kuwonongeka kwa silicon kudzera mu electromigration ndipo kumatha kuyambitsa latch-up kapena kulephera kosatha. Mayesowa nthawi zambiri amachitidwa pamayunitsi omwe atha kugwiritsidwa ntchito mokhazikika. Chiphuphu chili chonse chochitidwa ndi ichi chiziwona ngati chongoyesera kamodzi osati chida chopangira, ndipo musachigwiritse ntchito m'njira yovuta kapena yosayang'aniridwa.

Kodi pali njira zotani zogwiritsira ntchito kwambiri Pico 2 overclocking?

Mapulogalamu adziko lenileni ndi opapatiza koma ali ndi tanthauzo: mapulojekiti ampikisano a demoscene, zoyeserera zofananira, kukonza ma sigino ochedwa latency-critical processing, ndi kukankhira malire a kafukufuku wamaphunziro kapena osangalatsa. Kwa opanga ambiri, ma overclocking ochepa (mwachitsanzo, 300-400MHz pamagetsi otetezeka) amapereka zopindulitsa pakupanga ma audio kapena kuwongolera nthawi yeniyeni. Ngati mumakonza mapulojekiti angapo a hardware, nsanja monga Mewayz — yokhala ndi ma module 207 pa $19/mo — ingathandize kukonza zolembedwa, nthawi ya polojekiti, ndi kugwirizana ndi timu pazoyeserera.

Kodi ndimayesa bwanji kukhazikika kwa overclock pa Raspberry Pi Pico 2?

Kuyesa kukhazikika kumaphatikizapo kuthamangitsa zipsinjo - monga masamu ophatikizika kwambiri kapena njira zofikira kukumbukira - poyang'anira kuwonongeka, kuwonongeka kwa data, kapena kukonzanso kosayembekezeka kudzera mukudula mitengo ya UART. Gwiritsani ntchito mphamvu ya benchi yokhala ndi malire apano kuti mugwire anthu omwe akuthawa. Yambani pamabampu amagetsi okhazikika ndikuwonjezera pang'onopang'ono. Lembani zotsatira zonse mwadongosolo. Magulu a Hobbyist omwe amayang'anira zoyeserera zingapo amapindula ndi malo ogwirira ntchito; Mewayz ili ndi magawo 207 a zokolola ndi mapulojekiti oyambira pa $19/mo kuti musunge zoyeserera ndi zolemba zokonzedwa pazomanga zonse.
