Athlon II X2 (Regor) overclocking?

[rogue1979]

I plan on overclocking an Athlon II X2 240.

Since it is only a 65 watt cpu, won't any decent overclocking motherboard get the job done?

Or would I need to make sure and get one with a SB750? Isn't that only necessary for higher wattage AMD cpu's?

The SB750 wasn't designed to overclock higher wattage AMD processors, it was designed to give ACC(Advanced Clock Calibration) to the original Phenom line up allowing them to overclock better. ACC has no effect on overclocking with the newer Athlon II/Phenom II processors, however it is used to unlock cores on some processors.

I'm not too familiar with what would be a good overclocking board, I'm a BE user and personally have been using 780G or 790GX boards myself. I would imagine any decent overclocking board as you put it will work fine.

^ +1 for that... i use a Gigabyte GA-78GM US2H board and i'm OC'ing from 2.8 to 3.2ghz... well it works fine...

SB750 is only for ACC and support for Xfire

I use a gigabyte ma770-ud3 rev 1 with the 700 sb and this is what i got last night.http://img44.imageshack.us/img44/2879/aod3850.png tonight i might crank up the volts and see how far it goes.I used a arctic cooling freezer 64 from a 939 build

that is very promising considering the sargas+gigabyte 785G combo for $96.

I got that cpu to use with my old motherboard, the Asus M2N32-SLI Deluxe. While i am happy that it runs on that board i just cant get it to overclock decently. The max I can get it up to is 3.1 ghz and even then i am having problems keeping that baby stable. I dont know about you guys but i cant set the multiplier any higher than 14x.

thanks,I think new egg felt bad about the all the dogs they sent me over the years and finally sent a good one.I didn't have a chance stress test those clocks but this is what i run 24/7 for the last 2 weeks http://img171.imageshack.us/i/247clocks.png/ and idle http://img42.imageshack.us/i/247clocks2.png/ I quoted you before i read your sig,sorry about that

byteman99 14 is as high as the multi goes on the 240,it sounds like your mobo or ram is holding you back,What memory are you using?

 

[byteman99]

I am using a 2GB stick of g-skill memory. And the mobo im using is the one i posted earlier.

and temps

Update*

You were right. The RAM was holding me back. I lowered the speed of the RAM to DDR2 667 speed and I was able to get a bit further than yesterday. I was able to push the frequency speed all the way up to 260 this time. But the computer would crash 2-3 minutes into running Prime95. Right now im working on getting this thing stable.

Does anyone know the thermal spec and the v-core spec for these? I dont want to go over the limit there.

[hdfxst]

The max is supposed to be 1.425 but i've seen people going over 1.5,keep the temps under 60,this is as far as i would go http://valid.canardpc.com/show_oc.php?id=707773 i just wasn't comfortable raising the voltage any more.not bad for a 56 dollar cpu and 65 dollar motherboard

 

[byteman99]

Looks like I hit the wall with this cpu. The highest frequency it will load into windows is at 263. After that it just wont boot. This is with the v-core set to 1.5v. I suppose i could go higher but i dont feel like its worth the risk. Now i just have to work on stabilizing it.

This is an old motherboard. The new cpu's are not supported to run on them. Much less give me a decent overclock.

 

[byteman99]

After a couple of days of tinkering with this cpu i got it up to 3.5ghz stable. Im pretty satisfied i was able to do this with an older motherboard.

From what I've read over on the Asus forums, it is because your BIOS doesn't recognize the CPU, so it doesn't know that it should enable the extra power phases of the motherboard. So, your processor is basically power starved and/or isn't receiving clean power.

People who have spoken with Asus technical support have reported back that Asus has no plans to give official support to AM3 processors, so whatever you get above stock is a wonder in itself.
