Should I go for higher???

I currently have my mobile 2500+ at 2400mHz at 1.65v. Should I try and get higher speeds? I think my board undervolts as much as .04v so most of the time it hovers around 1.61-1.62 under load. Just wnat your opinions.
 
Most would recommend it. Why not? See what that beast can do. At the least you could see if another volt you would get at least 100 mhz. If another volt gets you almost nothing you know you're reasonably stuck at 2400.
 
Mine's at 2.5 Ghz right now on 1.725 volts... it's not perfectly stable though... and I think I may decide to run it at 2400 Mhz since it 'll run there at 1.625 volts, which will keep temps down a lot.

Some questions first. What heatsink/fan are you using? What is your load temp running at 2.4 @ 1.65v?
If you have a good heatsink and your current load temp is less then 45C, I totally recommend bumping the voltage to say 1.8 and set the CPU to 215x12 and see what happens. But that's just me, I don't hold back. Good luck.

Wow. Nice temps and 2.4ghz on 1.65v. You do realize that that is the stock voltage of a desktop athlon chip right? You should be fine up to 1.85v since you have such excellent cooling. I have a feeling you could get at least 2.7ghz out of that bad boy. Good luck!
 
Just an FYI on your temps. The Athlon boards read the temperature in the socket under the CPU, not from the diode. When using a high speed, high CFM fan like the Tornado's, you make the reading even more inaccurate as the sheer force of air skews the temperature readings underneath the socket.

The real core temperature of your Barton is probably about 10-15c higher than what your boards is giving you....not a problem..just an FYI.


Congrats on the overclock...I was lucky enough to get a XP-M 2600+ that does 2.5Ghz on 1.65v, but it seems that even for the best of these CPU's, 2.5Ghz is the high end, unless you want to run super high voltages.. Mine runs about about 50C idle, and 58C under full load with a Alpha 8045 and a low speed Coolermaster QLED fan, and two L1A Panaflo's exhaust. I love the quiet of this system, and I don't know how anyone can take the 50dBa+ levels of these high speed fans..

:beer:
 
I'm not running the tornado at full speed so I don't think that is affecting the temperatures. One of the reasons why my temps are low is because I have my case side open. I believe these temps are accurate because when I went from my old heatsink to my new heatsink I saw a drop of about 8-10C which is what I expected.
 
Not running it full speed does make a difference, but the readings on *any* Athlon board, other than the older 8K3A's, is a temperature reading from the socket under the CPU. The core isn't even exposed on the bottom of the CPU packaging, so there is no possible way the temp readings are true representations of the true internal core temp.

The newer boards do monitor the CPU's internal diode, but only for the purposes of emergency shutdown on overheat.

Since Barton stock Voltage is @1.65v I believe, getting your mobile to that voltage is equivalent to running at default voltage anyways. Now apply +5% voltage increase on the safe side and you should be safe at around 1.75V.

Also if you are going to upgrade within next 9-12 months, you can safely push to 1.85V. The cpu will not die before 1 year at these voltages. Of course this only makes sense if you are able to achieve higher speeds like 2500-2700mhz.

He's on a Barton M. Stock voltage is 1.45v.

I know that stock voltage is 1.45. But barton M is the same core as Barton only run at reduced voltages. That means if you run at it 1.65 that is the same as saying you are running at stock voltage. The processor is of a higher grade that it is able to run at a lower voltage in the first place and that is how they pick whether it will be a mobile or not.

That is why P4 2.4 - 3.2 is the same processor but the VCore fuctuates between 1.48 and 1.55. Then if you set your 2.4 to 1.55 you are more than likely to get that magical 3.2 figure, but you can think of it as still running stock because that is the stock voltage ceiling for the whole family.
 
not bad now put it too 1.75 and go for 2.5-2.6 I run mine at 1.825 with no issues but by the time this chip goes poof I'll be do for an upgrade anyway 😀
 
I might try for 2.5-6 ghz soon... I'm leaving to go back to school tomorrow so I won't get a chance for a couple days. I don't want to go over 1.75v. I would love it if I could hit 2.5gHz.. Then the only thing holding me back would be my geforce3 and my slow harddrive. I wish I could afford new stuff 🙂

You will definitely notice the difference if you are an FPS pusher/benchmarking freak.

With that cooling and a mobile you can up the voltage way more than that safely...just don't run it at high voltage 24/7. Mobiles are hand-picked to be able to take higher temps (laptops get hot). I've had my t-bred a at 1.95vcore with a crappy coolermaster and it stayed below 55c (only kept it there to run a benchmark). I'd say you would be safe at like 2vcore, but I'm probably riskier than you. Since you have such nice cooling, I'd say up it to 1.85-1.9 but keep your temps below 50c under load if you're worried about it so much, thats perfectly safe to run a mobile at.

 
all right, nice overclocks guys! i picked up a mobile 2500+ last week and can get 210x12 @1.8v. i just did the vcore voltmod to my a7n8x deluxe today to see if i could go up a multi by upping the voltage a bit more. my temps @1.8v were about 39c idle and 47c loaded under prime. how high of temps do you think these things can ran at and remain safe? i put my voltage up to 1.9 and went up to 12.5x210, but temps were pretty high; about 65 loaded under prime. im using a alpha 8045 heatsink with 4krpm fan. how high is safe? what kinda temps does everyone else like to stay under?
 
I wouldn't feel safe at all at 65c. Keep it under 60 at load at least. I don't even like my chip over 50c at load. 55 is where I draw my line, even though I'm sure it can take more heat
