Help with Noob OC!

post #1 of 7
Thread Starter 
Thanks for visiting! I'm fairly new to overclocking laptops without an option in the Bios, so I was looking for some assistance!

I appreciate everyone who views and helps with this!

I have an Acer Aspire 7551-2575 with an AMD Athlon II x2 P320 (2.1 GHz)
I'm running Windows 7 Home Premium.

Yes, it was stupid of me to go for the lower grade processor, but I was strapped for cash!

I'm trying to overclock it, and as stated there's no option in the bios. What do you guys think is the best/safest way for me to OC it? I was thinking of bringing it up around 2.5-3.0 if it's safe to do so, and if I do this should I increase the fan speed as well?

Any thoughts?

Thanks, all posts are appreciated!

Overclocking an OEM laptop... seems a bit difficult to me.
BTW Welcome to OCN

I would worry because of the temperatures in the laptop, plus most OEMs don't include the OCing option simply because they don't want you to do it or it will void your warranty.

Thanks for the welcome!

Yeah, I figured it would be difficult to do it. I've heard there's some programs that'll do it for you, but I haven't been able to find much on Google that isn't more than 2 years old, which as we all know makes it ancient.

There might be a way to do it, like flashing with a customized BIOS but I doubt it would be smart.
If you are looking for better performance you could try reducing running Windows services with a program. Using a startup manager you can delay or even stop certain programs from running at startup which helps you get to down to business instead of waiting for Windows applications to load at startup. It helps also to use a browser like google chrome or something else that is lightweight. Depending on how much RAM you have taking advantage of ReadyBoost can help. On my GF's laptop Adobe CS3 would take 14 seconds to load. We then tried ReadyBoost with a 4GB USB stick and the load times after a few restarts dropped to about 3 seconds! ReadyBoost has to be "trained" by running the program a few times with the memory stick/card in... A good disk defragmentation program helps too, not to be too obvious . I use all these programs personally and they are free. You could also consider dual-booting Linux. It is super fast and not as vunerable to malware and viruses as Windows is currently. I personally like Linux Mint. Good luck!

You can try SetFSB but you need to know the PLL of your motherboard and hope it's supported.

I can't think of anything else though, good luck anyway.

Edit: Bear in mind stuff like your battery life will go down and your temps will go up.

Edit edit: Found a few more programs.

Ok, im kind of in the same position as you, and want to overclock my acer laptop (still no luck in finding something that that will work with this motherbaord/cpu XD). You can try setfsb/clockgen (they dont have much support for acer motherboards, but there are a few, maybe you are a lucky one?)

Also the overclock you want is completely impossible, not only could your laptop not cool that, and you would probably fry your mosfets, and would probably get hardware failure from such a high fsb speed lol.

I dont think you could really go much higher then like a 220mhz fsb, and for that it would be better if you had a laptop cooler + arctic silver/ic diamond thermal waste on your cpu. Like my cpu has a x12 multiplier, and i wanted to take it to 2.6ghz from 2.4, which is probably a more likely possible solution.

Since you have a K10 cpu like me look into K10stat (used for settings voltages for different Pstates). can use to undervolt, so you atleast get lower temps/longer battery life if you are unable to atleast overclock. Though even if you can overclock, good to be able to change voltages. i wouldnt go above stock voltage on a laptop though. https://sites.google.com/site/k10stat/


As for geckyl's reply:
1) Disabling services will NOT increase performance, it will actually lower performance depending on what you disable.... services only really use resources when they are called upon. when they are not being used, they use hardly any ram.

2) delaying startup entries wont change much, but initial boot time. Yes if there are processes you dont want to auto startup, you should disable. you can do it by going to start > type in msconfig.exe (btw ccleaner > glary utilities)

3) iobits software sucks... and for defrag, auslogics > smart defrag.

4) ready boost does almost NOTHING for performance in any computer that has more then like 2gb of ram, its no different then the paging file on your hdd. his laptop has 4gb, so adding paging file/readyboost will do nothing...
And ofcourse the load time of a a program that is cached will be faster....


Though dual booting a linux distro does have many uses, using it because "not as vunerable to malware and viruses" is ignorant. How the hell do you get a virus/malware on windows? "click here to download a free xbox360" derp OK!

i havent gotten any virus/malware since i was like 12... and that was back in the day when it was much easier to get infected, now with all the free security and free tools you have, its like literally impossible...

Thanks for the tips! I'm reluctant to flash the bios, as I don't want to wreck it being OEM and all. I've tried all programs listed and none wanted to work due to the motherboard. I'll just leave it for now and get a custom build when I've got the dough. Thanks everyone!
