Emachine E625 Disasssembly

Anyone here ever try to upgrade the CPU on one of these things? Looking for disassembly instructions. if anyone has them I really could use them.
Thanks.

 

I've just upgraded the CPU in my E627, which I believe is the same machine as yours except for the OS. I took pictures of the disassembly and can write up a guide if you're still looking for one. Let me know.

FYI, the computer's CPU socket is S1. I replaced the original CPU with a 1.9 GHz Turion 64x2 TL-58 that I got on ebay for $35 + shipping. My "new" CPU is a 31W TMDTL58HAX5 DC, where the "DC" part is significant because the other variants of the TL-5x chips run hotter at 35W TDP (vs. 15W for the original TF-20). The computer definitely runs warmer now, but I haven't seen the CPU temps go over 60ºC and this is well within the CPU's 95ºC limit.

Any S1 CPU should work so you could also look for a mobile Athlon 64x2, but the L2 cache is usually smaller on the Athlon chips. The 1.6 GHz Athlon TK-42 was interesting at 20W TDP, but I couldn't find one anywhere.

CPU specs can be found at www.cpu-world.com.

 

If anyone is interested, someone has posted a guide on the Acer forum: http://forum.notebookreview.com/showthread.php?t=435567

 

Hey i just got a emachines e627-5279, can you email me the disassemble instructions, as well as the dual core processors that are compatible? thanks.

I was also contemplating the same upgrade and would appreciate your guide if it differs from the Acer. How has your user experience improved and do your feel it is worth it to add ram or a 7200RPM hard drive?

 

The disassembly is the same as for the Acer. There may be an additional cable or two to unplug if your machine has a webcam (mine didn't) and I may have used different techniques here and there (e.g. I used my fingers to pry up the button board from the keyboard side instead of a screwdriver on the hinge side) but the steps are the same.

Any socket S1 CPU will fit and should work but I suggest a Turion 64x2 TL-5x (TL-50, TL-52, TL-56, TL-58) for greatest bang for the buck. The aforementioned Athlon 64x2 TK-42 (if you can find one) or another Athlon 64x2 TK-5x should work too. I went with a Turion because I've heard they perform a bit better than their Athlon counterparts (perhaps because the Turions have more L2 cache).

A list of the Turion 64x2 CPUs can be found here: http://www.cpu-world.com/CPUs/K8/TYPE-Turion 64 X2 Mobile technology.html

The Athlon 64x2 CPUs can also be found on that site. The RM-7x Turions and the QL-6x Athlons found at the bottom of each list use a different socket (S1g2) so don't try those.

As for user experience, sorry but I couldn't really tell you if there is a noticeable improvement. I barely used my e627 with the TF-20 before opening it up to swap in the TL-58. I'd have to say it probably won't make much difference if you're not a power user, although I've seen some complaints that the TF-20 can't handle Youtube videos in HD without stuttering (I didn't try it, I only have crummy "ultra-light" cable internet at home and even regular Youtube videos pause all the time).

More RAM? Depends again on what you intend to do with your computer. If you're a power user opening multiple programs or editing huge files then go for it. My e627 came with 3GB RAM, I probably won't add any more anytime soon.

Same goes for the HDD. Your needs may differ, but I probably won't upgrade mine unless it dies. A couple of months before buying the e627, I bought a Gateway laptop with a 7200RPM hard drive which I'm sure has gotta be faster, but for what I use these computers for (web surfing, small spreadsheets & light word processing) they both feel similarly snappy.

Generally speaking though, my rule is: if you don't know if you need an upgrade, you don't need it.

 

Thank you so much for your prompt and detailed reply. I will most likely use as is for awhile and then attempt the upgrade.

 

In the acer forum I've posted the results of my modding the same 627 that JimBob has using a 35w TL60. The performance increase is SUBSTANTIAL..roughly 3 times what the stock SF-20 can do. Similarly, under full game load, my box is maxxed out at between 55 and 60C, but under normal usage, temps run from 29 to 34c or so. serious *bang for buck* here.

Brief update on the TL60 experience in the E627. I've been experimenting with voltage and p state mods and now have the 60 running at .8v with temps during general internet surfing (such as now) of 23.2C.....yep you read that right.

I'm enjoying the modded 627 immensely.
