Hello everyone,

I have been working on computers since I've been 14 years old, I have a good grasp of programming and I understand a little on hardware... basically enough to know depending on what you want to do with a computer such as gaming you need a good graphics card, processor and ram (not to mention using the games requirements for hardware to get a good idea on what you exactly need.)

I basically want to attempt to replace my processor in my laptop. I have an acer aspire 5750z. I have 8gb of ddr3 ram and I have a Samsung 840 EVO SSD 500GB in it. I have also done some system optimization on it. I have replaced explorer.exe with a batch file I programmed so I can just access the programs I need from it... I did this to lower my processes on my OS. My processes are at 35 and I have a windows 7 home premium on it. I have also done a few tweaks on the registry to make my windows more responsive. I have not experienced any system instability and this setup works very well for me. I'm only wanting to replace my processor because this is more of seeing what I can do. I want to replace my CPU with a core i7 2620M. I've looked up most of the information on this seeing if I can and it looks possible... I also found a youtube video stating I could do this... however I would highly value an opinion of anyone who is better at this than me.

here is the old post I found on here that made me want to try to replace my processor:

http://forums.overclockers.co.uk/showthread.php?t=18370619

in the post it has another link to compatible processors. Just to make sure if my processor wasn't soldered in like most people claim most laptops do I looked up a dis-assembly guide and it looks like it can be taken out. I always do deep research before messing around with my computer. Can anyone give me some advice? Also I decided on the core i7 2620M is because of the turbo acceleration feature the i7s have. I also updated my BIOS for my laptop in case when I do get the processor. I do play games on my laptop and I also love to see how fast my computer is. I also plan to buy a new battery to double my battery life and a backlit keyboard for my laptop as well.

So... I guess what I'm asking is to summarize it... Am I going the right way with this to replace my processor? What should I expect when doing this? Will the turbo acceleration feature work with this once I do replace my processor? because on you tube he does get the processor to work but it doesn't let him use it... should I expect that to happen to me? Thank you everyone for taking the time to read this. I hope to hear any suggestions you could give me.
 
thank you rtho782 for the advice. I'll have to try to contact Acer somehow with that question... that's why I updated my BIOS... but I didn't see what exactly it changed.
 
So I installed my processor and after LOTS of effort I got it to work... now my next issue... I can't get my turbo acceleration to work. I got my turbo acceleration monitor program installed and it is stuck on energy saver mode... I stress tested my processor with Prime95 to see if I can make my intel monitoring program do something... but nothing happened. So from what I have looked up that means the acceleration isn't enabled. Also, I checked to see if I had bios options to enable hyper threading or something I can change to fix this... I also tried looking up updated bios and still no luck. I also looked for hacked bios to give me options for my computer and nothing... any other suggestions?

NOTE: If I can't enable turbo acceleration maybe I could try to overclock... but I would only want to go as high as 3ghz because with this all being done in a laptop I don't wanna risk overheating... so any suggestions about this I would also appreciate. Thank you :-)
 
So i found a program called throttlestop. After doing some testing with it I found out the turbo boost works on it. For some reason the turbo boost monitor program I used wasn't reading it properly. Ran some pc games and it shot up to 3200 to 3300 mhz. I also tested the power saver feature of throttlestop and it help my processor to stay at 798 mhz when at rest... when it wasn't enabled it was flexing aroun 798 to 1498. I have to say I'm very happy with this find. The processor I bought only cost me $34 USD. It was a Intel core i7 2620m and it bump my Windows user index from a 4.7 to a 5.9. The processor prongs were bent so I ran my insurance card through the prongs to straighten them out lol.

Thank you unclewebb for that version of throttlestop. I'm currently using version 7 of that. Ill have to try this one out as well :-). Also thank you jpod it was definitely a learning experience. This was my first time trying this. I tried going to best buy or micro center around my area and they always told me I couldn't because the processor was always soldered in the motherboard :/. Now I'm gonna buy a battery for my laptop that will prolong its battery life unplugged... I've already added the max ram my motherboard can handle and I've added a ssd as well... and with the processor... honestly I don't what else I can do... I've even got my processes between 35 to 40 processes running... is their anything else I could do? I've also altered my registry a tad... mostly for my Windows popping up faster and using a ACCESS.BAT file I made to replace explorer.exe to make a list of programs and whichever program I wanna pop up I just type the number in on the number pad and press enter and it runs.

Yea :-) I helped my friend with his desktop a little while ago. He installed 32gb of RAM and his OS wasn't recognizing it all. He doesn't mess with software much but it was because his OS was windows 7 home premium. It only recognizes up to 8gb from what I've seen so we upgraded it to Windows 7 ultimate and it fixed it. I've also put in led lighted fans in towers, I've modded my xbox360 with clear ghost casing with green led lights, I have some experience with soldering, and I also know batch programming and I'm working on python.
 
Oh current update on the laptop... I gotta replace the fan... I'm pretty sure it's because of the dust that was built up in it when I cleaned it I think it over worked the fan and since I haven't thoroughly clean the fan in a couple of years I think it wore out the fan bearing. Easy fix though :-).

that bar top arcade looks amazing! To use MAME for that it's a very good idea. The whole thing looks so retro. I love retro games. Are you going to paint yours? Thank you for the Sig but i decided to make mine.

I have decided to take this post down I will be doing my own editing on it. if I come across the things that I need to do I will post my results in the future.

I'm also sorry for the delayed response to your comment. It be also cool if you could make stencils and put different retro game characters on it. I would also like to make one of those in the future. Right now I thought of more things to do with my laptop and I'm looking into doing a airflow mod to it... basically cutting a hole where the fan is and putting some metal mesh in place of the plastic i cut out. Basically the airflow will help with cooling and prolonging my laptops lifespan... I know it'll get more dust in it but I plan to disassemble it to clean it once a month. I added velcro to the back of my laptop for my externals... I love it lol. I don't have to worry about them falling off the table. I also been looking into higher frequency RAM... interestingly enough I learned about latency in RAM and how they have specific timings... problem is I don't know how to tackle this... right now my RAM is 1333mhz with timings of 9-9-9-24. According to my research lower timings is better... my RAM type is DDR3 and I've been searching around and the best ram I found was 1600mhz with the same timing of 9-9-9-24. I really don't know how I could measure the performance differences and based on the programs I use speeds can very... so my question is would higher frequency RAM with the same timing as my old RAM show a slight difference?

here is the link to what I read about RAM timing:
http://www.hardwaresecrets.com/understanding-ram-timings/

P.S. I'll post my laptop with the Velcro on here in a couple of days.

To be honest, you're more likely to damage the components by repeated reassembly or accidental expose to built-up static electricity, than you ever are to experience overheating/failure because of dust.
I talked to a professional computer repair technician from a well-known PC/laptop-building company a few years ago, and he told me just spraying some compressed air into the exhaust vent while the laptop's off once a month would do the trick.

Thank you Malamo999 for the detailed reply :-). I honestly didn't consider the damaging of components... I'll take your advice on that as well as the dusting. I plan to attach a fan underneath my laptop to the air mod I really want to do... basically drill out where the plastic is near the fan. I'm hoping to get it to look like this:

maxresdefault_zpsravxfdal.jpg


gotta get the mesh from a metal strainer and looking into some O Rings that are metal and spray paint it all black. Gotta find some good paint to stick to metal.

Generally, the greater the frequency, the greater the timings. If you want higher frequency RAM (which you'd already be paying a premium for) with similar timings as your current RAM, you're going to be thinking about paying a lot more. Also, it might not even be compatible with your motherboard, and probably isn't with your new processor (check Intel Ark) - so although your laptop might boot with new RAM, it might automatically keep the it clocked at 1333MHz, which would be extra disappointing and a waste of money.
Click to expand...

I kind of figured that and I thought how I could get my RAM to read on my motherboard so I have a theory... stil looking into it. So I found out that a processor can only read a certain frequency from ram on a processor.

For example my intel core i7 2620m processor:
http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7 Mobile I7-2620M FF8062700838809.html

if you look look on the page you'll see this further down on the specs of it:

Integrated peripherals / components

Integrated graphics GPU Type: HD 3000
Base frequency (MHz): 650
Maximum frequency (MHz): 1300
The number of supported displays: 2
Memory controller The number of controllers: 1
Memory channels: 2
Supported memory: DDR3-1066, DDR3-1333
Maximum memory bandwidth (GB/s): 21.3

So I made a comparison to another processor which is better that is suppose to be compatible:

Intel Core i7-3840QM


Now look at this:
Integrated peripherals / components
Integrated graphics GPU Type: HD 4000
Base frequency (MHz): 650
Maximum frequency (MHz): 1300
The number of supported displays: 3
Memory controller The number of controllers: 1
Memory channels: 2
Supported memory: DDR3-1333, DDR3-1600, DDR3L-1333, DDR3L-1600, DDR3L-RS 1333, DDR3L-RS 1600
Maximum memory bandwidth (GB/s): 25.6

The red is the frequency I want to use on my motherboard. I used CPU-Z to look my my mother board specs and I don't see a frequency limit... which leads me to think the reason why it wouldn't be a waste of money to buy it is because the processor is what limits the motherboard from obtaining benifits from high frequency RAM.

Here is the RAM I'd like to get:

** No Competitors **

I mean that's what I'm assuming... I mean if you look up your Max RAM for your motherboard on your laptop model shouldn't there be a frequency limit list by your RAM amount?

If I'm wrong please let me know this is all I have found by myself I'd hate to spend money on something I can't use lol.

I will build a good desktop eventually but I really enjoy the portability of my laptop :-)

Oh here are the pics I promised to upload:

After reading your comment I double checked the price and I agree that's insane to spend. I'm hoping to find the processor cheaper than that. I may be able to find it in a used computer at a thrift store or just wait till it becomes cheaper. I got my processor which was the core i7 2620m for 30 USD. It just had bent prongs I fixed with a card. I honestly think it would work and I probably should upgrade my rig but I just find it fun to see how far I can take it. My games run pretty good but I also do penatration testing with my laptop as well... as a hobby. I program too for fun. That pic with my screen on my laptop i use that to navigate through my laptop. Explorer.exe I replaced with a .bat I made so I can navigate with my num pad. I always wanted a laptop when I was younger so it's also very sentimental to use this laptop. It's the first decent laptop I've ever owned.

What I'm trying to say is based off my current processor I know it won't read 1600 mhz fully on the new RAM I plan to get but if I somehow get this processor then it might based on what I've found on the specs. If I also upgrade the processor it will give it HD 4000 integrated graphics on my laptop not HD 3000 like I have now. I've also tried to find specs on my motherboard and it doesn't say how much mhz it can use... So I'm guessing it's the processor specs I should go by.

And according to this site the Intel Core i7 2620m has integrated graphics in the processor itself:
http://www.notebookcheck.net/Intel-Core-i7-2620M-Notebook-Processor.40108.0.html

I'm hoping with the new processor and RAM and if I can do it under $100 USD would be nice. I know I'm being optimistic but I'm hoping for at least a 25% to 30% increase in response time on my laptop. With new graphics and a slightly higher ghz in processing power I think it's doable.


my motherboard comes up as JE50_HR on my Acer Aspire 5750z

Thank you Sliver :-). I'm glad I posted. Normally I keep my projects to myself because no one around me where I live is "tech" literate... so to explain what I do for fun they don't honestly get it.

I use Kali Linux actually lol. It's a fun thing to tinker with. I checked your link and I'm gonna try to see what processor it has on his by trying to contact him. However, the 1600mhz I want still has the same voltage (1.5) and I need to see if they are going by the processor which is why the specs say it can only read 1333mhz. I'm definitely keeping note of that for the desktop :). I REALLY want to try and make this for testing my network eventually:

I'm probably not as much of a gamer as everyone on here but I love the overclocking aspects of hardware.

Just a current update for this OP I joined the Acer community and I'm trying to contact the person who posted the thread provided to me by Malamo999:

http://community.acer.com/t5/Legacy-Laptops-and-Netbooks/Aspire-5750G-RAM-upgrade/td-p/355562

hopefully I will hear from him soon and I can finish what I started here lol. I looked for the processor I wanted to use and sadly the processor is too expensive for me to do :(. Even if I found a used laptop and salvage it for the laptop itself is roughly 2 to 3,000 USD and I'd be better off upgrading that laptop... It supports much more ram and lighter weight. If I find the processor cheap I'll go for it but right now I'm at a stand still.

Here is something I found though I've been considering trying though:
https://www.youtube.com/watch?v=uhw1n1N0hD0

It's a cooling mod for a laptop... issue is every pump I see are kind of big. I would like one smaller and portable otherwise what's the point of doing all of this with a laptop? I want portability.

right now nothing new on the processor. Still looking for something cheap. Havent finoshed the airflow mod either. Been pretty busy lately. Also been tinkering with my bat OS on my free time. I had a question for anyone willing to answer this... has anyone made it possible to switch a battery supply off with a switch? I mean taking it out and running it on just the power cord is something I've been doing lately because my battery is draining fast. I need to get a new battery but i want to find a way to switch it off somehow with maybe modding the battery connect so i dont have to pull the battery out. Anyone have any ideas for this?
