Si kasta oo ay kombuyuutarradeenu u yihiin wax sixir ah, kuma socdaan dhunkashooyinka unicorn iyo boodhka cirfiidka. Dhammaadkii, waxaa jira koronto duug ah oo wanaagsan oo dhex socota xididada kombuyuutarkaaga. Sida^(Just) qalab kasta oo elektaroonik ah, qaybaha ku jira kombayutarkaagu waxay ku shaqeeyaan danab gaar ah. Taasi waa, cadadka cadaadiska ku riixaya elektarooniga ee wareegyada ku jira kumbuyuutarkaaga. 

CPU -gaaga waxaa loogu talagalay inuu ku shaqeeyo koronto gaar ah, laakiin waxaad hagaajin kartaa lambarkaas si uu u sarreeyo (kor u kaco) ama ka hooseeya ( hoos u dhaca). Waa kan dambe (hoos u dhigista CPU ) waxaan rabnaa inaan kaga hadalno maqaalkan, waxaanan ku bilaabaynaa su'aasha ugu muhiimsan marka hore.

Waa maxay sababta ay hoos ugu dhacayso CPU?

Elektroonikku 100% tayo wanaagsan maaha. Taas oo macnaheedu yahay in qaar ka mid ah tamarta korantada ee dhexmaraysa CPU kaaga ay isu rogtay kulayl. Taasi waa sababta CPU -gaagu ugu baahan yahay kulaylka iyo taageeraha si aanu u kululayn. Yaraynta tamarta CPU sidoo kale waxay yaraynaysaa xadiga elektarooniga ah ee ku dhex qulqulaya nidaamka. Tani waxay u tarjumaysaa kulayl yar. 

Faa'iidada ugu horreysa ee tan waa in qaboojiyaha CPU uu lahaan doono cimri dheer. Sidoo kale, dhimista danabka CPU^(CPU) waxay sidoo kale ka dhigan tahay in CPU uu isticmaali doono awood yar. Markaa aaladaha ka shaqeeya batteriga, hoos u dhigista waxay noqon kartaa hab lagu kordhiyo nolosha batteriga. 

Hoos-u-dhigiddu waxay sidoo kale noqon kartaa hab lagu gaaro xawaare sare oo saacad ah xaaladaha qaarkood, halkaas oo heerkulka sare uu xaddidayo dadaallada xad dhaafka ah. Si kastaba ha noqotee, inta badan waa xad-dhaaf taas oo u oggolaanaysa xad dhaafka^{(overclocking)} xasilloon , markaa hoos u dhigista CPU ma aha habka loo tago ee waxqabadka junkies.

Maxay U Shaqaysaa Hoos-u-dhigiddu?

Waxaa laga yaabaa inaad la yaabto sababta ay soosaarayaashu u dejiyaan CPU-yadooda^(CPUs) koronto gaar ah marka ay ka shaqeyn doonaan mid hoose. Ka dib oo dhan, haddii hoos-u-dhigiddu ay aad u weyn tahay, maxaad u soo dejin weyday CPU-yada^(CPUs) tamarta hoose? Jawaabta tan ayaa ah in CPU-yada^(CPUs) mid walba uu ka yara duwan yahay. 

Laba CPUs oo isku mid ah ayaa ku yeelan kara natiijooyin kala duwan marka loo eego tamartaas hoose. Korontada la ansixiyay waa midda la dammaanad qaaday inuu la shaqaynayo boqolleyda ugu badan ee soo-saareyaal. Xaaladaha qaarkood CPU shakhsi ahaaneed ayaa runtii la shaqeyn doona tamarta rasmiga ah, laakiin inta badan waxaad ogaan doontaa inaad hoos u dhigi karto ugu yaraan wax yar oo xun.

Hoos-u-dhac ma khatarbaa?

Jawaabta su'aasha ah in hoos-u-dhigiddu ay khatar tahay waxay inta badan ku xidhan tahay waxaad u aragto inay khatar yihiin ama nooca khataraha aad ku qanacsan tahay. Yaraynta tamarta CPU ma dhaawici doonto CPU ama qaybaha kaleba. Si kastaba ha noqotee, waxay abuuri kartaa xasillooni darro nidaamka, taas oo markaa horseedi karta luminta xogta. Markaad hoos u dhigayso waxa muhiim ah in aad tijaabiso oo aad xaqiijiso goobta tamarta hoose ka hor inta aanad wax ka fog fog ku samayn kombiyuutarkaaga.

Marka laga reebo luminta xogta suurtagalka ah, khatar kale oo dhab ah marka ay timaaddo hoos u dhigista waa inaad si lama filaan ah uga gudubto ^(overvolt)CPU - gaaga . Korontada^(Too) badan waa hab degdeg ah oo wax ku ool ah oo si joogto ah loo shiilo CPU , markaa hubso 100% inaad u jeedinayso garaaca korantada jihada saxda ah!

Hoos-u-dhac ku yimaada BIOS-ka

Habka ugu nadiifsan ee aad hoos ugu dhigi karto CPU -gaaga waa BIOS . Taasi waa firmware-ka ka dhigaya kombuyuutarkaaga inuu shaqeeyo ka hor inta uusan bilaabin nidaamka hawlgalka. Motherboard kasta wuxuu leeyahay menu-yada BIOS oo kala duwan , magacyo iyo tallaabooyin. Markaa waa inaad tixraacdaa buug-gacmeedka Motherboard-ka si aad u ogaato meesha saxda ah ee aad aadi karto si aad u bedesho tamarta CPU ee ^(CPU)BIOS -ka . 

Iyadoo tani ay tahay dariiqo sharci ah oo hoos loogu dhigi karo CPU , isticmaalka BIOS waxay noqon kartaa mid aad u caajis badan. Maadaama dib u habeyn kasta ka dib waxaad u baahan doontaa inaad gasho Windows , samee imtixaan ka dibna dib u hagaaji. Habkan dheer ee ansaxinta ayaa ah sababta dadka intooda badan ay u isticmaalaan utility software si ay u khalkhaliyaan korontadooda.

Ka digtoonow haddii aadan haysan BIOS -ku- jihaysan wax-qabad , waxaa suurtogal ah inaysan jirin kontaroolada korantada CPU ee aad ku hagaajin karto.^(CPU)

Hoos-u-dhaca CPU -ga oo leh Utility Software^{(Software Utility)}

Waxaa jira laba utility oo caan ah kuwaas oo si xun u shaqeystayaal u isticmaalaan inay CPU-yadooda^(CPUs) ka saaraan casiirka. Haddii aad isticmaalayso Intel CPU , markaa Intel Extreme Tuning Utility (XTU) waa doorasho wanaagsan. Qofna ma yaqaan CPU-yada^(CPUs) Intel si^(Intel) ka fiican Intel , ka dib oo dhan.

Nasiib darrose, barnaamijku maaha midka ugu saaxiibtinimo badan adduunka oo wuxuu leeyahay goobo badan iyo qaybo badan oo jahawareer ku noqon kara haddii aanad aqoon u lahayn dhammaan ereyada CPU^(CPU) . Nasiib wanaag hoos-u-dhigiddu waa inaan daryeesho oo keliya tiro yar oo habayn ah. Gudaha XTU kuwani dhamaantood waxay ku hoos jiraan qaybta "core" ee abka. Waxa muhiimka ah waa "core offset voltage".

CPUs-yada casriga ah^{(Modern CPUs)} , gaar ahaan kuwa laptop-yada ku jira, ma isticmaalaan danab taagan. Taa baddalkeeda, danabku waa la hagaajiyaa iyadoo loo eegayo xaddiga rarka ee CPU . Tani waa mid ka mid ah sababaha hoos u dhigista aysan helin natiijooyinkii ay hore u ahaan jirtay, maadaama CPU ay dhab ahaantii hoos u dhigayso marka ay shaqaynayso. Anagoo hagaajinayna danbi-dhaafka danabka, waxaan bedelnaa inta ugu yar iyo inta ugu badan ee tamarta uu CPU isticmaali doono.

FIIRO GAAR AH:^{(NOTE: )} Haddii aad aragto in Core Offset Voltage uu cawlan yahay, tani waxaa suurtogal ah inay sabab u tahay balastar ammaan oo OEM (Saaraha ^(OEM)Qalabka^{(Equipment Manufacturer)} asalka ah ) ay hirgeliyeen. Tani waxay inta badan saamaysaa laptops-yada, laakiin waxay sidoo kale run ka noqon kartaa hababka desktop-ka ee horay loo dhisay.

Tani waxay mahad iska leedahay ka faa'iidaysiga jabsiga ee loo yaqaan Plundervolt . Sida kaliya ee shaqada dib loogu soo celin karaa waxay noqon doontaa in la ifiyo nooc ka da' weyn oo aan la xirin oo BIOS ah^(BIOS) , haddii la heli karo. Kuma talineyno inaad tan sameyso ilaa aad si sax ah u garaneyso waxaad sameyneyso.

Marka, ka waran isticmaaleyaasha AMD ? Ma aanan haysan mashiinka AMD si aan u tijaabino, laakiin mabda'a ayaa weli sidiisii ​​ah. Arrinta ugu weyn ayaa ah in XTU aysan la shaqayn AMD CPUs . Akhbaarta wanaagsan ayaa ah in AMD ay leedahay adeeg u gaar ah oo loo yaqaan Precision Boost Overdrive .

Nooca ugu dambeeyay ee software-ku wuxuu bixiyaa sifo hoos-u-dhac ah oo la-qabsiga kaas oo saameyn weyn ku yeelan kara waxqabadka, kulaylka iyo nolosha batteriga. Markaa haddii aad isticmaalayso AMD CPU dhawaanahan hubaal eeg.

Tijaabinta Dejintaada Awoodda La'aaneed

Meel kasta oo koronto cusub ah waxaad u baahan tahay inaad hubiso in wax walba ay wali u shaqeynayaan sidii loogu talagalay. Waa lama huraan in aad hesho shil ama habdhis habaysan mar uun, taas oo inta badan calaamad u ah in aad dib uga laabato hal ama laba darajo. Laakin xitaa haddii ay wax walba u muuqdaan inay fiican yihiin, waa inaad qabataa shaqo dhamaystiran oo xaqiijinta dejintaada. Waa kuwan taxanaha tillaabooyinka aanu ku talinayno marka hoos loo dhigayo CPU:

1. Kahor intaadan wax beddelin, socodsii bartilmaameedkaaga CPU oo qor dhibcaha. Qor heerkulka ugu sarreeya ee CPU kaaga . CPU-Z waa barnaamij aad u fiican ujeedadaas.
2. Iska yaree danabka 5mv. Haddii aad dareemeyso geesinimo waxaad heli kartaa bilow bilow ah oo leh 50mv dhimis, halkaas 5-10mv ayaa ah kororka ugu macquulsan.
3. Ka dib dhimista, samee tijaabada cadaadiska sida Prime95 ama tijaabinta diiqada ee XTU .
4. Haddii aad u malaynayso in tijaabada diiqadu dhaafto, mar kale ku celi bartilmaameedkaaga. Waxqabadku waa inuu ahaadaa mid la mid ah ama ka sii wanaagsan.
5. Ku soo celi habka.

Haddii CPU -gaagu uu noqdo mid aan xasiloonayn ama waxqabadkaagu bilaabo inuu ka sii daro marka loo eego bartilmaameedkii hore, garaac korantadaaga isku daygii ugu dambeeyay ee guusha oo u isticmaal sidii goob aad u tagi lahayd.

Undervolting waa qabow, macno ahaan

Overclockers iyo mavericks kale ee CPU ayaa wax badan u qabtay warshadaha xisaabinta oo dhan. Maanta CPU-yadu^(CPUs) aad bay ugu fiican yihiin inay isdhaafiyaan, isla markaana waxay noqonayaan run hoos u dhigista.

Dhawr sano gudahood ma jiri doonto wax badan oo laga faa'iidi doono gacanta hoos u dhigista CPU , taas oo ay ugu wacan tahay is-tweaking casriga ah ee CPU-yada^(CPUs) cusub . Si kastaba ha ahaatee, weli waa mudan in lagu sameeyo kombiyuutarada hadda iyo kuwa hore. Waxa ugu fiican ee ku saabsan waa in ay jirto khatar aad u yar. Haddaba maxaad u siin weyday go'aan?

How to Undervolt a CPU on Windows 10

As magical as our computers may be, they don’t run on unicorn kisses and fairy dust. In the end, there’s good old electricity running through your PC’s electronic veins. Just like any electronic device, the components inside your computer run at specifіc voltages. That is, the amount of pressure pushing electrons through the circuitѕ inside your computer. 

Your CPU is designed to run at a specific voltage, but you can adjust that number to be higher (overvolting) or lower (undervolting). It’s the latter (undervolting a CPU) we want to discuss in this article, and we’ll start with the most important question first.

Why Undervolt a CPU?

Electronics are not 100% efficient. Which means that some of that electrical energy running through your CPU is turned into heat. That’s why your CPU needs a heatsink and fan assembly so it doesn’t overheat. Reducing the voltage of a CPU also reduces the amount of electrons flowing through the system. This translates to less heat. 

The first benefit of this is that a cooler CPU will have a longer lifespan. Also, reducing the CPU voltage also means the CPU will use less power. So for devices that run from a battery, undervolting can be a way to extend battery life. 

Undervolting can also be a way to achieve higher clock speeds in some cases, where high temperatures are limiting overclocking efforts. However, it’s usually overvolting that allows for stable overclocking, so undervolting a CPU is not the go-to method for performance junkies.

Why Does Undervolting Work?

You might wonder why manufacturers set their CPUs to a certain voltage when they’ll work at a lower one. After all, if undervolting is so great, why not ship the CPUs at the lower voltage? The answer to this is that CPUs are each a little different. 

Two identical CPUs can have different outcomes at those low voltages. The approved voltage is one that’s guaranteed to work with the largest percentage of processors. In some cases a given individual CPU will really only work with the official voltage, but for the most part you’ll find that you can bring it down at least a little without any negative effects.

Is Undervolting Dangerous?

The answer to the question of whether undervolting is dangerous depends largely on what you consider to be dangerous or what sort of risks you are comfortable with. Reducing the voltage of a CPU won’t hurt the CPU or any other components. However, it can create system instability, which can in turn lead to data loss. When undervolting it’s important to test and validate your lower voltage setting before doing anything remotely important with your computer.

Apart from potential data loss, another real danger when it comes to undervolting is that you accidentally overvolt your CPU. Too much voltage is a fast and effective way to permanently fry a CPU, so make 100% sure that you’re turning the voltage dial in the right direction!

Undervolting Through the BIOS

The purest way in which to undervolt your CPU is the BIOS. That’s the firmware that makes your computer run before the operating system even kicks in. Each motherboard has slightly different BIOS menus, names and steps. So you’ll have to refer to your motherboard manual to know exactly where to go in order to change the CPU voltage in the BIOS. 

While this is a legitimate way to undervolt a CPU, using the BIOS can be incredibly tedious. Since after every adjustment you’ll need to boot into Windows, run a test and then adjust again. This lengthy process of validation is why most people use a software utility to mess with their voltages.

Be aware that if you don’t have a performance-oriented BIOS, it’s possible that there are no CPU voltage controls for you to tweak.

Undervolting a CPU With a Software Utility

There are two popular utilities that avid undervolters use to wean their CPUs off the juice. If you’re using an Intel CPU, then the Intel Extreme Tuning Utility (XTU) is a good choice. No one knows Intel’s CPUs better than Intel, after all.

Sadly, the program isn’t the most user-friendly in the world and it has a heap of settings and sections that can be confusing if you aren’t familiar with all the CPU jargon. Luckily for undervolting we only have to care about a small number of settings. In XTU these are all under the “core” section of the app. What matters is “core offset voltage”.

Modern CPUs, especially those in laptops, don’t use a static voltage. Instead, the voltage is adjusted as per the amount of load in the CPU. This is one of the reasons undervolting doesn’t get quite the results it used to, since the CPU is actually undervolting itself when idle. By adjusting the voltage offset, we change the minimum and maximum voltage range the CPU will use.

NOTE: If you see that Core Offset Voltage is greyed out, this is possibly due to a security patch that some OEM (Original Equipment Manufacturer) have implemented. This mainly affects laptops, but can also be true of certain prebuilt desktop systems.

This is thanks to a hacking exploit known as Plundervolt. The only way to get the function back would be to flash an older unpatched version of the BIOS, if available. We don’t recommend you do this unless you know exactly what you’re doing.

So, what about AMD users? We didn’t have an AMD machine to test, but the principle remains the same. The main issue is that XTU doesn’t work with AMD CPUs. The good news is that AMD have their own utility known as Precision Boost Overdrive.

The latest version of the software offers an adaptive undervolting feature which can have a significant effect on performance, heat and battery life. So if you’re using a recent AMD CPU definitely look into it.

Testing Your Undervolted Settings

With every new voltage setting you need to make sure everything is still working as intended. It’s inevitable that you’ll get a crash or system freeze at some point, which is usually an indication that you have to back off a notch or two. But even if everything seems fine, you’ll have to do a thorough job of validating your settings. Here’s the sequence of steps we recommend when undervolting a CPU:

1. Before changing anything, run your CPU benchmark of choice and write down the score. Make a note of the peak temperature of your CPU. CPU-Z is a great program for that purpose.
2. Reduce the voltage offset by 5mv. If you’re feeling brave you can get a headstart with a 50mv reduction, from there 5-10mv is the most sensible increment.
3. After the reduction, run a stress test such as Prime95 or the built in stress test in XTU.
4. Assuming the stress test passes, run your benchmark again. Performance should be the same or better.
5. Repeat the process.

If your CPU becomes unstable or your performance starts to get worse compared to the previous benchmark, dial your voltage back to the last successful attempt and use that as your go-to setting.

Undervolting is Cool, Literally

Overclockers and other CPU mavericks have done a lot for the entire computing industry. Today CPUs are very good at overclocking themselves and the same is becoming true of undervolting.

Within a few years there won’t be much to gain from manually undervolting a CPU, thanks to sophisticated self-tweaking in new CPUs. However, it’s still worth doing on current and past computers. The best thing about it is that there’s very little risk. So why not give it a go?
