BIOS: cosa modificare?

[lollo78]

Ciao a tutti,

nella speranza di ottimizzare le prestazioni del mio hackintosh (preciso che funziona tutto alla perfezione), ho deciso di tentare la strada del BIOS mod mettendo mano a tool come Ru.efi o Setup_var.efi.

Prima di fare danni, però, vorrei però confrontarmi con voi.

 

Il mio hackintosh è un laptop HP 250 G7 con CPU i5-8265u e IGPU UHD 620 al quale ho sostituito un fottio di cose, tra cui l'SSD (Crucial P5 Plus 1 TB PCIe M.2 2280SS | CT1000P5PSSD8) e la RAM (2 x 8GB Crucial CT8G4SFRA266 8GB DDR4 2666MHz CL19).

Come si vede dalle immagini, attualmente le RAM funzionano a 2400 Mhz e non a 2666 Mhz. Inoltre, l'NVME sembra che funzioni in gen 2, ma si tratta di un gen 4.

 

Oltre alle varie ottimizzazioni lato Config.plist che riporto di seguito e che vi chiedo cortesemente di verificare prima di applicarle, vorrei cercare di spremere (se possibile) le prestazioni dell'hardware in mio possesso.

 

Avrei pensato, pertanto, di muovermi come seguie (allego TXT del Dump del BIOS).

 

Ottimizzazioni generiche:

 

1) Attivazione del menu nascosto Advanced nel BIOS (non sono sicuro che si faccia da qui!)

 

VarOffset: 0x489

VarStore: 0x1

Disabled: 0x0 (default)

Enabled: 0x1 (da impostare!)

Ottimizzazioni legate alle prestazioni (ho fortissimi dubbi che siano queste le sezioni nelle quali smanettare!):

 

1) Impostazione del gen 3 (supportato in teoria dalla CPU) per cercare di sfruttare al meglio l'SSD Crucial P5 Plus (che teoricamente ha Velocità di lettura sequenziale fino a 6600MBs e Velocità di scrittura sequenziale fino a 5000MBs).

3) Impostazione timing delle memorie (le mie RAM hanno JEDEC: 19-19-19)

 

Non ho idea di come agire per questa modifica, ma ipotizzo che la sezione sia questa:

4) Undervolt di CPU e GPU per evitare il Thermal throttling

 

Anche qui non saprei dove agire.
Credo che ci sia qualche altro blocco da disattivare, visto che nel mio BIOS l'Overclocking Lock è disabilitato di default, ma nonostante ciò i parametri di undervolt impostati con VoltageShift non sortiscono alcun effetto.

 

Infatti, nel mio caso:
One Of: Overclocking Lock, VarStoreInfo (VarOffset/VarName): 0xDA, VarStore: 0x3, QuestionId: 0x16E, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 5B 03 5C 03 6E 01 03 00 DA 00 10 10 00 01 00}

0xB57DF One Of Option: Disabled, Value (8 bit): 0x0 (default) {09 07 04 00 30 00 00}

0xB57E6 One Of Option: Enabled, Value (8 bit): 0x1 {09 07 03 00 00 00 01}

0xB57ED End One Of {29 02}

 

 

 

Sono nelle vostre mani!

Grazie in anticipo per tutto l'aiuto che saprete e/o vorrete darmi.
