i5 - 3.8 plafon

[Lukija]

Ja sam sa Q9450 i DDR2 imao ~47GFlopsa na 3495MHz

Znaci Q9450 na 3495MHz je priblizno brz kao i i7-860 na 3800MHz sa HT on , ako je verovati LinX-u

 

[voodoons]

Ne, nego tu nesto ne valja sa sistemom..

 

[Lukija]

Ne, nego tu nesto ne valja sa sistemom..

I ja mislim. Meh, Intel sux

 

[Iv4n]

@Lukija - da li si probao da obrises LinX folder i skines ponovo program sa neta?

Ako je gledati ostale rezultate za isti procesor, Linx bi trebao da pokazuje oko 10Gflops vise

 

[Lukija]

Jesam, skinuo sam nove Intel linpack libraries. Nije u tome poenta. Poenta je da LinX sa HT off pokazuje bolje rezultate. Meni to nista ne znaci jer mi je u realnom radu HT vazniji (zato sam naveo x264 kompresiju). GFlops jos zavisi od svega i svacega tako da nije pouzdan pokazatelj performansi.

EDIT: Ovde ima dobro poredjenje HT off vs HT on (i turbo on/off):

MOj zakljucak je da RealTemp prijavljuje lose temperature i da treba koristiti CoreTemp

To su OK performanse. Tvoj CPU radi na 3.54GHz i imas samo jedan kanal aktivan i imas nesto labavije tajminge.

Nasao sam zanimljiv gadget - monitor turbo od intela

Takodje jedno pitanje ... sta izabrati od ponudjenih C State stanja ?? Nisam bas apslovirao temu ali nesto oko iskljucivanja pojedinih jezgara ?? Da li ostaviti na AUTO ili izabrati C1, C3 ili C6 ??
Odnosno za OFFSET voltazu ??

Basically though there wasn't much to change, I bumped up the CPU Vcore and the IMC voltage a bit, then made the speed changes. The board has a feature, as discussed in the article, called offset voltage, which I was a little weary of, and didn't use, but that's really because I couldn't be bothered finding out how to set it correctly, and if you have the time then definitely give it a shot, because it means that when SpeedStep lowers the multiplier it also lowers the voltage, further lowering idle power consumption and temps.

Hvala

Offset podesavanje voltage

Sada sam probao da podesim vcore sa offset voltazom i dobio ono sto me zanima, kada je proc idle malu voltazu a kada je u loadu podize voltazu, postoji strah od podizanja voltaze na preko intelovih 1.4 pa me zanima vase misljenje

kod loada je uglavnom zakucana na 3.6 i voltazom od 1.35 i u retkim trenucima ide na 1.415 a u idle je smesna

evo slika

Ako rucno podesis napon, i spustis ga na oko 1.28v - verovatno ces smanjiti maximalnu temperaturu procesora za oko 8-10 stepeni.

Evo rezova sa Mushkin memorijom ?? Cini mi se bolje

 

[demios]

Koliko si ti Gflopsi vazni? Moj predlog je da pustite ovaj benhmark jer je realniji pokazatelj performansi:

http://www.techarp.com/showarticle.aspx?artno=520

vazni su. moze da se desi ako zafali vcore-a ili qpi/vtt napona, da izbacuje manje gigaflopsa tj kao da trotluje i da ne opterecuje i zagreva cpu maximalno, iako prolazi linx.

shto se tiche i7, neki je bug u pitanju sa linxom i uvek sa HToff izbacuje vishe gigaflopsa negoli sa ht on, iako se cpu vishe opterecuje bez sumnje i mnogo vishe greje sa 8 tredova

Evo i ja sklopio kantu konacno pa krenuo da se igram. Za prvu sam probao sa vasim podesavanjima na 4; ovaj test prolazi ali linx puca na tacno 54 sec

Ono sto me brine jedino je systin u temperaturama koji ode u trenutku na 74 stepena kada pokrenem linx iako temp procesora ne prelazi 68 stepeni po jezgrima!!

 

[Proday]

Samo da pitam da li treba da brinem zbog ovih temp oznacenih u attachu?!

 

[Oki]

Ne. Zasto bi brinuo ?

 

[Proday]

Pa ne znam na sta se te temp odnose (sta je to uopste) ali su prilicno visoke!

 

[Lukija]

Probaj Everest. Jedna od tih temperatura je temperatura CPU-a merena termistorom, ostale su uglavnom temperature chipseta, ploce i slicno.

 

[OCz]

Izvinjavam se sto hijackujem ovu temu, zanima me da li 100c tjmax za 750 ?

 

[zookarma]

Izvinjavam se sto hijackujem ovu temu, zanima me da li 100c tjmax za 750 ?

Tcase je 72,7 ali mislim da tjmax jeste 100c, mada se svi trude da za 24/7 ne prelazi nikad 70 c

 

[OCz]

Ma ni ne pitam ja da bi terao procesor do 100c, vec da znam koliko da unesem tjmax da bi mi program(i) pokazivali pravu temp. I meni 100c izgleda najrealnije, a na netu nisam nasao proverenu informaciju. Trenutno mi je na procesoru stock hladnjak ispog koga sam stavio kaladont posto nisam imao pastu - zato i proveravam posto ne znam koliko mi je kompetentna orijentacija. Inace idle je tu negde oko 45c do 50c pri najblazem load-u @ 2.4GHz pri ~0.8v - tako dok ne vidim hladnjak, a i igram se sa memarom trenutno ..

 

[Proday]

Ja bio ubedjen da je 95 za i5!!!

 

[voodoons]

kako sam ja razumeo tjmax filozofiju, nema pravila za tjmax.. Isti modeli procesora mogu imati razlicit tjmax

 

[OCz]

Tako bese neka prica ranije, ali opet moramo da unesemo neku brojku koju smatramo najpribliznijom u programe.

Ja bio ubedjen da je 95 za i5!!!

Bas sam cesljao po netu i izgleda da se najvise ljudi slazu da je 99c, mada je sam kod mene zaokruzio na 100c.

Ali zašto???
Prvobitna uloga paste je bila sasvim drugačija od današnje. Trebalo je da kompenzuje mikroneravnine nastale mašinskom obradom na površini heathspreadera i hladnjaka CPUa... a danas i da kompenzuje toplotu i odradi njenu što bolju konvekciju...
Bolje d si stavio direktno metal na metal i uživaš dok ne nabaviš pravu ili ti željenu termalnu pastu (ne verujem da je toliko "puklo" da si morao kaladont da stavljaš)!

Da ali su razlicita revizija odnosno stepping
