Max bench on OCCT
3441Mhz on AirCooling (+115,07 % compared to stock :up: )

Big Vdroop again and again on P5KC ^^ (i use the pencil vmod of vdrop but no change for vdroop)

I mounted 2 DELTA 120mm 190CFM (2 ventil 120mm 76CFM before) on RAD Thermalright IFX-14

Shouldn't this be moved to the Intel section?

[KumKum]

no pb for me :D ;)


Max FSB on AC (vcore 1,50v)

Update

test on DoD Max FSB and Max screen (see the first post)

[M3kk]

3600 with this cpu, aircooler its ok? :)
I will try with vapo too.

[KumKum]

update whith the last BIOS for P5KC, the 903
betters results (see first post)

[fragmasterMax]

So whats the maximum stable clock so far?
Great job btw

[before]

Update

test on DoD Max FSB and Max screen (see the first post)

You may wish to write "Single Stage" instead of "DoD" (Direct on Die)... :)

[KumKum]

Ok before

So, update max bench tonight allways on AC

the preceding result of 3303Mhz is beaten and more "than a little" ^^

3417Mhz

See "last update" in first post for screen and valid CPU-Z

[KumKum]

better again in last Max bench on Aircooling for this E2140

Max bench to 3427Mhz stable for 1.49v Vcore in full (+ of 114% compared to stock)

see last update in the first post

[smsmasters]

Can you get it to 450x9 on air? Nice overclock.

[KumKum]

hi

its a Pentium Dual Core E2140, i forget you

This coeff max is 8 (so not possible 9x450)

after on AC, i go step by step (im very patient no pb lol ;-) )


PS :
it did better in max bench AC ^^ (I finalize the lasts tests to put them online)

[KumKum]

With the 2 ventilators 120mm of 76CFM on Thermalright IFX-14 not possible to do better in AC that 3436Mhz

Valid CPU-z online --> http://valid.x86-secret.com/show_oc.php?id=300426


but i want to stabilize it in more of 115% of its value stock ^^

i mounted my best ventilators 120mm , 2 DELTA 190CFM :p: :D
5 and 9° Celsius of better according to the phases of calculation of OCCT and it stabilizes itself on 3441Mhz (+ 115% of its value stock :up: )

see last update in the first post :)

[KumKum]

update Max Screen under AC and the BIOS 903 always in Vcore of 1.54v



This last max screen in this parameters in Aircooling with Vcore of 1,54v Screen --> http://picasaweb.google.fr/PhilMorning/E2140MaxScreenSousACVcore154vBIOS903/photo#5154621721698067650
Valid CPU-Z --> http://valid.x86-secret.com/show_oc.php?id=296364
3398 Mhz already not badly



AND NOW, after several stable hours of benchs under OCCT at various frequencies and vcore
it is better and much better even :up: (with the same components and under the same BIOS 903 of course)

Positive grinding ?? ^^
the fact can exist on CPU sometimes and I believe it for this one :D

hi

more news for my OC of this E2140

the main thing and the last :
I succeeded to stabilize it under AC (large AC but AC lol, IFX-14 +2 ventil Delta 190CFM ^^) more than 125% of stock

3.603Ghz for Vcore of 1.44v bench +2H OCCT !!

To finally see what promises it powerfull E2140 that I test in this moment (3641Mhz, stock + 127.59%, stable OCCT+1H on Air with 1.44v of Vcore) and now i have the pretty ^^ P5K Premium Black Pearl Edition (I have also Dfi P35 LP DK T2RS, but its BIOS too young compared with the powerful BIOS of Asus and of best of Asus P35, the P5K Premium, and especially it is unstable and currently refuses booter with E2140 even whith very small little OC, it is much more perf with E6850, strange ???), I thus have passed 3H of bench SuperPi 1M this afternoon
Before having repaired his big point pb (the only big pb ^^) : i do Vmod of Vcore, it's Vcore limited to 1.70V under the BIOS and its damage to exploit it when one has an extreme cooling (SS 1 cp rotary 8000 BTU)

So...

4th world score SuperPi 1M of E2140 (Hwbot) 15.484s :)

this E2140 waiting now my new cascade 2 stages and Ln2 that I can still push frequency CPU and I think sure ^^, go up on the podium and peraps a little bit better , "wait and see" :D
