Aspire 5315 CPU Step-by-Step Upgrade Guide

My memory is as listed in my sig, Kingston HyperX CL4, 1Gb in the lower slot, 2Gb in the upper slot.

I had a look at the spd settings for the OCZ ram (2 2Gb chips, but not bought as a set) as I was curious to see if it was an alternate to the HyperX for CL4 working at 667Mhz.

I can't remember the exact timings, they were better but still at CL5.

I should have another set passing through my hands in the near future as I have been asked to upgrade an Acer 5050-3502 AMD S1 system which the owner would like upgraded to a good Turionx2 and 4Gb of fast RAM. I'll have a look and post what I find.

This will be a more challenging upgrade than usual as it has a Portugese version of Vista loaded which is sufficiently different to cause confusion !

 

have you gotten all the windows XP updates installed... if not do that and install SP3, i have yet to hear of any SP3 issues with the ASPIRE 5315.

what are you using to control the power managment? are you just using XP's built in features? or are you also using ACER's E-Powermanagment? and what BIOS version is currently installed?

asking a good question is not hi-jacking,,, and we are more than happy to help... as Quilty and others have said, pc6400 will work perfectly fiine, and i recommend it to PC-5300 since the prices are almost identical. while the intel 965 chipset is limited to 667Mhz as the MAX RAM SPEED, you MAY get lower latencys (depends on the RAM's specs).
To get the best performance from your ram i'd recommend buying the lowest latency ram you can find... and when looking at the HIGH-END ram, it may be cheaper to buy PC-5300 CL4... rather than PC-6400 (i don't even know if CL4 is available @ 800Mhz).

but if just buying general purpose ram then PC6400 should be the same price as PC5300,, so why not buy the faster speeds.... that's my take on it anyway.

hope that helps.

sounds like it's time for a comparison with some benchmark tests to show us the difference!!

BTW.... sorry for the disappearance... and i'm glad to be back!

 

when I replace a new cpu T5550 for my aspire 5315, the installation of ACPI multiprocessor PC can not run because it is not pass the Windows Logo TEsting. I have tried " Continued Anyway" and then the window is not start up. Please help me when I check in the task manager. it only show 1 graph-cpu

 

Does it say something like: "The software you are installing has not passed windows logo testing to verify its compatibility with this version of Windows: The software will not be installed" ??

Make sure "Cryptographic Services" is running.

Start -> Run -> services.msc > Set "Cryptographic Services" to Automatic.

 

ANDY,,, where did you learn of that little tidbit of info? i'd be scratching my head into next week trying to figure that out

 

I just thought it might be related to it. When I upgraded to Vista, I was reading loads of guides and blogs related to tweaking vista, and the services windows explains and gives the description of each service. Cryptographic Services has also something to do with automatic updates (which I wanted to get rid of ), so as it has something to do with Root Certificates, it might be the possible cause, if the OP is running Vista

 

i guess that could cause the problem... i keep forgetting about VISTA... (on purpose)...

i've found i can fumble my way thru it when setting at a VISTA machine, but i don't want the ability of knowing vista like i know XP.... that way i can send all those poor VISTA users somewhere else and not be lying when i tell them i'm not familuar with it

i know when i upgraded mom's VISTA 5315 with a 5450 it booted up, detected new hardware, asked to be restarted and then worked flawlessly after a reboot... so i think you may be on the right track... there is something turned off or some software that is preventing THANGBOOM0007's system from adding the driver for the dualcore cpu...

worst case, he could reinstall vista or use the factory restore CDs to get it lined out... i know it's a drastic solution... but with my limited knowledge of VISTA,,, it's the best i can think of!

 

Windows XP SP3 here.

I tried to use all sorts of possible methods (NHC, E-powermanagement,xp built in feature,etc..)

It worked at a point, which is what is making me more "angry" about this...

BIOS was 1.43 downgraded to 1.42 to see if the BSOD's I occasionally have stopped (they didn't though).

 

if it were me, i'd uninstall all third part apps like NHC, and also uninstall the EPOWER MGMT and the E TECH FRAMEWORK... then reboot...

next try using the windows POWER MANAGMENT SETTINGS in the control pannel... it sounds to me like you have 2 or 3 different things all trying to control the same features... my advice is to get rid of all the un-needed stuff and let windows do the power managment. see if that helps..

and the BIOS should have little to no effect on the actual power managment. so you can use either version of the BIOS as long as you are not having other issues due to the BIOS downgrade.

hope that helps.

 

thanks for your replies. My "Cryptographic Services" is automated, but it still not work. Do I need to re-install Win XP?

 

Wait....try this first http://support.microsoft.com/kb/293765

Or this http://www.mydigitallife.info/2007/...ver-installation-dialog-prompt-in-windows-xp/

 

are you currently doing a complete re-install or just in this because a cpu upgrade tried to install a new file but that file failed?

 

I think this problem is not cause by Windows Logo TEst, because when this warning pop up, I chose " continue anyway". Like bigozone said, when I upgrade my cpu, new file installed but the window do not start up. But when I don't install new file, the window start up normally, but it only detect one cpu in task manager.

 

Which Service Pack ?
Try windows update and download/install all critical updates ?
(And checked the above links ?)
Also try installing ACPI multiprocessor PC manually in Device Manager....

 

thanks for you replies. I use Windows Xp service pack 3, I tried to update and also install ACPI Multiprocessor but when I installed ACPI Multiprocessor, the window does not start up. Should I re-install win Xp?

 

Disabled Driver Signing Check ?

Try a repair install first....
Which BIOS version ? (>1.31 ?)

Also, after the driver is installed, with the C2D in....Does the notebook not POST, or it just does not load windows ??

 

if i am understanding thangbom, when he loads the driver then windows locks up while loading... and he was having some other issue too..

so since nothing seems to solve the issue, i'd backup all my important files and stuff (pictures, music, ect) if you have your HDD partitioned into 2 drives just copy everything to the D: drive, then reinstall windows... or use a factory restore disk... which ever method you perfer.... be sure to load sound drivers before anything else (don't ask, it just solves problems)..

that's what i would do if you are not too attached to your current setup

 

If its locking up at windows boot, he could either try a safe-mode boot or a repair install, with the C2D installed. During the repair, windows will install the appropriate driver....

 

not a bad idea.... i've never really used the repair option of the recovery console but it should work just like you say.

 

When you get to the partition/drive selection screen, there is an option to Repair a particular XP install by pressing 'R'....

Such a brilliant thread for us 5315 owners...

Has anyone tried one of the new medium-voltage Penryn processors (P9500, P8400 or P8600) on 5315? They're socket P processors too, so I guess they should work, as long as the motherboard/BIOS supports them? Or will the faster FSB (1066MHz) cause problems?

I think one of those should be really sweet for the battery life, since they have a TDP of only 25W (compared to 35W for other C2D processors). Should run quite cool too...

Thanks in advance.

 

as i understand it those CPUs use a different pinout, even though both will fit a 479PGA socket, even if the pinouts were the same the higher voltage would likely burn out that type of CPU,,,

they are incompatible,,,, that is why intel used a different letter as a prefix to the CPUs model # (using a P instead of the older T)

my T5450 rarely turns the fan on, it's that cool.. and newer CPU designs like the T8300 or T9300 run even cooler...

 

my bios is v1.35 do i need to update to the newest before I repair or re-install win?

 

Okay, I guess I'll get a T8300 instead then (or maybe even 9300, but they're quite expensive). Any C2D will probably give a better battery life than a Celeron, anyway... (never mind the performance difference)

Thanks

 

Just want to say a quick thanks. Just upgraded my cpu on my 5315 to a T7500. Got it for a bargain price aswell, £35.

Wouldn't have been able to do it without this thread.

Cheers guys.

 

i would consider updating it... ver1.35 was never made public if that tells you anything... ACER released ver 1.34 then the next public release was 1.40.
i doubt the bios is your problem though so you shouldn't have to flash it if you don't want to... to me your problem sounds like some of the windows files are damaged,,,, and that should be solved by reinstalling the OS.
if you do flash the bios use ver 1.43 or higher

the T8100 may be a bit cheaper than the T8300,,, but like you said ANY C2D will give better battery life and should also OUT-PERFORM the celeron due to the 2 cores.... a T5450 should be selling for $50 to $60 on ebay.

glad to help, that was my whole motivation in starting this thread.... it's nice to see users getting more than they thought they could out of these low-end laptops

 

No cigar..loosing hope and patience trying to fix this

 

ok you have all third party applications for hardware control un-installed,
and the acer stuff is un-installed..

now what are you trying to enable or disable, and what happens when you use the windows POWER MANAGMENT to make those changes...

and which OS are you using?

 

Hi everyone.

I posted a thread on the forum a week ago asking for help reinstalling windows using the recovery CD after putting Linux on my system. Well, it turns out that all I had to do was completely erase the hard drive for the CD to work. So now I have Vista on my 5315.

I put in 4 GBs of RAM while I still had Ubuntu because I was anticipating putting windows on it again. I haven't gotten any problem yet except the computer only reports 2 GBs of RAM. I already flashed the BIOS to 1.43. Will Acer ever come out with a BIOS that supports 4 GBs of RAM?

So the next thing I want to do is change out the CPU. I see used t5450s for $60 on eBay and am also finding the t7100 for about $85. Is the t7100 worth the slightly extra money?

edit: Nevermind about the RAM. It turns out one of them wasn't in securely. I fixed and and booted the computer up and it gave me the BSOD. So I took it out and running 1 x 2 GB and 1 x 512 MB. Hopefully I can use the other 2 GB stick...soon.

 

hi there,

who knows if Acer will ever re-write the BIOS to use all 4gigs, you can run a 2gig stick with a 1 gig stick and the system will recognize all 3 gigs so that is the way to go.... i can't recall which slot the 2 gig stick must be in... so just try it out... if you get Blue Screen lockups, just swap the location so that the 2gig stick now in the other slot and then reboot and see what happens.

if buying a CPU right now, the lowest i would buy is the T7300, but the T8300 and T9300 are good deals.
that T7300 should be about $120 max i'd guess... it's been a week since i checked. but any CORE 2 DUO CPU is much better than the celerons that came in the 5315... so even a T5250 at $40 to $50 is not a bad deal.... but it's best to buy a bit higher up the chain. the T7300 or T8300 are good deals

you want to sell that extra 2 gig stick? i could use one!!

 

bought the T5450 new on ebay months ago for under $60 i believe (cant remember the exact price) but im looking to go higher now because I can Whats better for performance? T7300 or an extra gig of ram (bringing me to 3gb)?

Also I have always been the type to throw compatible ram into a pc without looking at latency and timings and things....so I am wondering what the best 3gb combo I could put into the 5315

 

buy the T7300... the increase of the FSB to 800Mhz is a much more often used feature, so you should upgrade it first. with XP you may never even use all 2 gigs you currently have... but you'll be getting your value out of a CPU upgrade everytime you boot up! as far as i know the best ram you can buy for these systems is PC-5300 with CL4 latency times of 12-4-4-4 i think kingston makes a decent priced one... then there are the EXPENSIVE RAM but the CL4 kingston is almost as good as it gets. and there is no need to buy pc-6400 ram if buying CL4, it only costs more with out any performance gains.

 

Yes, all uninstalled

system standby and hibernate never seem to work.

Windows XP w\SP3

 

you have checked to make sure they are enabled in the POWER SETTINGs haven't you?? this is weird,, i've got both disabled on my system because i didn't like it going into standby all the time... and i want the HDD space that Hibernate uses... but my father's PC, also a 5315 running XP, has had no trouble with standby or hibernate

i will re-enable those features on my PC later this afternoon and give it a few tests....
but i'm afraid some of the files may have been replaced by one NHC or one of the other software apps you were using to try to control the power settings.
and if that is the case, the easist way to fix the problem is going to be to do a RE-INSTALL..

you can always try to do a REPAIR first,,, it might replace the power managment files with the originals from the install CD...

i'll post later with my results of enabling STANDBY and HIBERNATE....

 

Hi to all!
Thank to bigozone for the thread. I've read all post and I'm serious considering to upgrade my 5315.
I'm in doubt about chipset/core2duo compatibility to speedsteep features.

Hi, MrDOS001

 

do not doubt it,,, it works.... with my cpu under volted and all power managmnet features turned off i get a report of the battery having 2hrs and 37minutes of battery life remaining. i've tested it and i get 2.5 hrs out of the T5450. and you can run RMCLOCK even if you don't undervolt... just use it to monitor the CPU stepping up and down as apps are opened and closed!!

there is no problem with the CHIPSET not supporting C2Ds or the speedstepping.... now if you are wanting to run Virtual Machines,,, i think the 5315's BIOS was not written to take advantage of that feature,, but very few users need that feature, and those people would not be trying to use a 5315.

there are people running T9500 in Aspire 5315's, and you'll be amazed at the difference even a T5450 can bring out of your laptop....

if you are in doubt you might try asking other owners who have posted thier success in this thread...
i personally have 3 of these machines in "the family"... 2 of these have had thier CPUs upgraded to T5450s since APRIL 08. so that is 5 months the CPU UPGRADE has been running successfully in my mother's PC (we also upgraded her HDD to 200gig model because she is into the electronic scrapbooking, infact we had to buy her 1000gig (1Terrabyte) maxtor shared storage 2 NAS)

these poor little machines are limited by that intel x3100 graphics chip, but after you upgrade the CPU, the chipset is actually detected as i965.... i know the chipset is an i960gl, i have read the top of the chip (it's under the keyboard). and even though the chip is an i960, as soon as you drop in a C2D, windows detects new hardware and asks to reboot... that is some drivers and required files being added to the OS so it can see both cores. as soon as you reboot, run any software you can find.... even the intel chipid tool reports the presence of an i965 chip (see attached thumbnail).

all i can do is tell you my experiences and provide you with the info others have posted... NBR is a highly respected site and they would never allow a thread of this nature to exist it's info was not correct.... and the fact that it has been stickied so it is always on the front page should tell you something.

 

Already did a RE-INSTALL and it worked (went into suspend mode) but before I noticed (and haven't done anything) it went fubar again

 

if it BLUE SCREENED, did you get a chance to write down the STOPCODE.... that will help to diagnose the cause of the problem...

there is a setting somewhere that deals with AUTO-RESTARTING after an error that can cause the system to continously reboot... so change that setting if you can find it... i can't recall where that option is at, but i'm sure someone here will be able to tell us where it is.

 

Always on top of things. Thanks Man!

 

Thank you for the answer, bigozone.
I'm going to search a T8100 or T8300 for my 5315...

Can you tell me where you have found bios 1.44? In the Acer's Support site there is the v.1.43.

Hi, MrDOS001

 

i'd buy T8300 if i were buying a CPU now... back march, when i was upgrading the T7xxx cpus were still expensive and the T8xxx were just comming out so they cost too much then

all i can say about bios ver 1.44 is it came from acer

 

Sure, I've attached a screenshot of when it happened awhile ago and..just now (same error code)..

Reliability is lacking, which is an issue since I need the laptop to be stable due to the work I use it for...

 

That error is related to H/W. -> BIOS or driver issue....

Sorry, I didn't read your previous posts, but can you log into windows ?

 

Check memory. Use memtest.
To do that, you can use 'Ultimate Boot CD' (freeware toolkit, ISO downloadable from www.ultimatebootcd.com) then start your PC with this CD. DVD drive must be the first unit in boot sequence of your PC. Press F12 at bios startup.

Hi,
MrDOS001

 

Sure can, this error seems to be random, the laptop can be lots of time on during lots of different things fine and then...all of sudden and out of nowhere i get this

 

have you tried this??

Re: IE crashes XP with Stop Code 8e #4 Mar 16th, 2008 | Add to caperjack's Reputation | Flag Bad Post
your problem is not likely with spyware but with a driver/hardware conflict ,what usually fixes 8e stop error for me is to boot to winxp cd go to the recovery console and do a , chkdsk /r http://aumha.org/a/stop.htm

 

Do you have a Minidump folder in the Windows Directory ??

 

14 hours of memtest 86+ and no errors (thankfully)

Doing it now mate. Cheers

Edit: Done it and seemed to have fixed, will only know until it/if crashes though (thats good for any troubleshooting anyway so lol)

Correct


Thanks alot for the help folks.

BTW dunno why but Suspend mode started working again everynow and then (not as frequently as its setup, but its an improvement), hibernation though is dead (and yes its activated and it used to work too )

 

Can you upload the minidump ??
