X2 4400+ CPU MAX 2.5GHz???

Recommended Posts

My 4400 maxed at around 2700mhz but I had to go to 1.6v or maybe a little more and it got hotter than I was happy with - 60c or so under load if I remember right. I'm now running 24/7 at 1.5v @ 2607mhz rock solid stable (237 x 11, 9/10 divider - memory @ 200mhz.) Load temp stays below 50c now, idle 28-29c.

 

See my sig for my air cooling - nothing special really aside from the wonderful P180 case which has great airflow.

Thats always possible for manchester core, not the toledo's though. i cant get mine to 2.6GHz at either 260X10 or 237X11 at 1.59Vcore .. and its already at 58C. When i play games i'll use the 2.5Ghz settings i have in reloaded ...all others in 2.4. this are the summary for my temps.

 

Stock: I cant remember ... n too lazy to check now

 

2.42Ghz @ 220X11 1.43VCore

Idle: 37C/43C/46C

Load: 47/50C/47C

 

2.508 @ 227X11 1.49VCore

Idle: 38C/43C/47C

Load: 52C/55C/48C

Thats nice @lanceDiamond ... wish mine could get to those speed with those voltages. At 1.5v, mine will only passed up to 228htt .. i use 227. The temps seems to correlate with what i have(on load) ... but one thing i noticed on ur machine, the delta t is quite big .. thats almost 22C between idle/load temps.

 

Once i put in 1.65Vcore to try(still) to push it to 2.6Ghz ... i had to cut off prime95 after half an hour coz the temps already reaching 58C with idle temps of 39C. the way i look at it ... its just no go on my cpu. It took only about .05v to move from 2.42GHz to 2.508GHz ... and something must not be right when i have to crankit up by more than .15v to reach 2.6 from 2.508 and i still dont know wether its stable or not.

 

p/s: 1.65v .. thats brave .. hehe. I feel stupid doing it afterwards .. a lot of things can go wrong.

My x2 4200+ is Prime stable @2500 (250x10) @ 1.425 and then if i want to reach 2600 (260x10) Prime stable i have to go all the way up to 1.525.

 

I thought that was high, but judging from you results thats an acceptable voltage for 2,6 Ghz right?

 

My temps at 2,6 are 30-32 idle and 40-42 Full.

I really feel that 1.65 is just too high ..... somebody here at df-street blew his opty at around 1.7v or 1.75v if im not mistaken ..and that cpu generally accepts higher voltages than the x2.

 

im planning to go wc with swiftech Apex Ultra ... do you think with it mine can go up to 2.6 @ 1.55Vcore ? thats the limit im setting myself or maybe as high as 1.59v(for even higher clock perhaps .. maybe not .. im not that confident at all.)

 

 

Of course .. i have no problem whatsoever with the current speed .. its fluid. But thats only because i have never tasted the speed achieved by others .. 3.0Ghz .. fuhh or even more :) Congrats boys ..

theres quite alot people putting 1.7V to 1.75V through the X2 which shocked me, personally i wont go over 1.65V

ive also heard a few people say prime will fail if your temps are over 50C, understandable as my maxtcase is only 55C on a 4200 :(

thats almost true .. but not entirely true ... from my forum browsing ... i learned an interesting thing bout that prime temps ... somehow u'll be able to go below 60 and passed ur prime95 if u r on the tropical weather. I have only tested mine 2.508 @1.49v for 24hr load @52C and 2.607GHz @1.65v for 0.5hr load @ 57C. Ok the last one was just for 0.5 hour .. but theres this one guy from Singapore got his to 2.7Ghz @ 1.65v @ 60c load for 24hr.

 

The only conclusion i can make is this. yes u will fail prime95 but not because you are above 50c, its because your delta t is above ~22C. So for most peeps here with ambient in the 20s and idle at around 28C, 50C is the targeted temps. For me here in Malaysia .. ambient around 33-34C, idle around 35C-38C so its safe up to 57C-60C. now .. thats safe to prime and it should pass .. however since x2 goes up to only 65C(amd recommended) .. 60C is already considered dangerous .. even to me.

 

So, ii'll just have to be happy with my 2.42GHz which loads at 46C or my 2.5 which loads temp at 52C .. hence i have a reason to watercooled my rig .. hehe .. thats fun.

i too only have a maxTcase of 55C, but my chip has seen 60C, only briefly, but 60C all the same :S

 

since adding some watercooling my temps don't go above 42C and i'm overclocked to 2816MHz with 1.582v

still needs some work doing to it, all comments welcome :)

hehe, you're right, it is a noisy card and i have been thinking about silencing it

this is my first adventure into watercooling ;)

i was thinking of a dangerden nv78 block and maybe another single rad where the rear fan is :shrug:
