Athlon X2 4200+

[Xab]

Hopefully this isn't a stupid question , but I'm curious if anyone knows how far the 4200 can be overclocked with the stock cooling. I know I've heard people say this is an excellent overclocking chip, and my old P4 I was able to overclock by 15% just through the BIOS with stock cooling, so any insight would be appreciated =)

Well Anand got his up to 2.7 with a $30 cooler, so I think you could do 2.4 without a sweat on the stock cooler.

I got it to 240x10.5=2.52 easily with voltage at 1.425 in bios (actual voltage reading differ). Had a little problem with 240x11=2.64, but got it tweaked to run stable currently with voltage at 1.45-1.475. Runs idle at 35-40 and load at <50 now in the hot summer days.

[edit] Orginally I use Zalman 7000Alcu. Swich to TT BigWater just wanted to play with water cooling coz the kit fits very well insdie the P180 case. There's not a big differece in cooling performance. [/edit]

He wants reports of ocing with STOCK HSF!!! I would imagine 2.4ghz should be no problem but could be nearing the high 50's....

I am at 2.475ghz so far with the stock cooler, 51c max temp with 2 instances of prime95. I am out of town at the moment or would have tried for higher already. I may pull the water cooling out of my p4 system and see how high I can take it.

What volts?

My 4200@ 2.62 1.65 v stays in the 45 range with a Zalman 77000..

I've got the Stock HSF.. I was thinking about playing with it, just to see how it does..

2.4 Should work fine with stock cooling. You could probably get 2.5. IMO you could get higher, but I don't think it will pass 24 hours of Prime..... 2.4-2.5 will pass 24 hours of prime nicely with stock if you don't have a dud CPU.

2.3 tops. If you use your CPU at load all the time, it will crash if you go above 2.3 ghz.

jmo.

 

[chinkgai]

2.4-2.5 im guessing

but if ur gona spend a good chunk of change on the damn processor, why not spend another 20-40 bux for a good air cooler? should be a drop in the bucket if u got the flow for a 4200+

I think I have it at 1.45v, I can double check in a couple of days when I get home.

Sorry to be off topic, but how do you run 2 instances of Prime95? I tried launching the program twice, but only one Prime95 window appears (and one process when I look in Task Manager). Couldn't find it in the FAQ at mersenne.org, either. Thanks!

 

[chinkgai]

2 folders

Just was able to check this, thanks for all the replies. I'm going to be getting the Antec P180 case, since I saw someone mention it.

Can any of you recommend any specific fan products that will do better than the stock cooling, and aren't too expensive? Preferably something I can pick up at BB/Micro Center since I want to put it on right when I first build.

I generally leave my PC running 24/7, although I obviously don't tax it that often since I'm sleeping at times. If I could get 2.4/2.5 without doing anything drastic (water) then I would be pretty happy. Thanks

Yah. Maybe thats why I (a first time overclocker) was able to get my 3800+ X2 to 2.4 ghz on stock cooling. Max temp 52C. It ran two instances of Prime95 stable for 3 hours before I had to close them cause I wanted to use more than a web browser. The 4200+ X2 is clocked at 2.2 ghz to begin with, so I doubt it has any problems getting to 2.4 ghz.

Prime95 is pansy.

Run tmpgenc for a real stress.

HTH

 

[n7]

No, run S&M for an even realer stress

Oh wait, realer isn't a word...

 

[Hacp]

I'm running 1.42 volts for 2.6 GHZ.

Pansy as in 100% CPU usage?

 

[fatty4ksu]

Prime95=pansy benchmark


tmpgecn=what you actually use a CPU for

HTH

 

[chinkgai]

p95 isnt a benchmark

its THE program to run to test stability...dont listen to this newbie

 

[fatty4ksu]

LOL

 

[chinkgai]

LOLKTHX

 

[fatty4ksu]

We will agree to disagree!

If chinkgai's answer wasn't clear..

Put a copy of P95 in each of two folders. Start both. Stop them , and use ' advanced options ' to set CPU affinity; one for each cpu.. Then crank em up..

It was interesting, when I started testing my overclock; one core would error out and the other one would keep chugging along...
