800mhz SODIMM DDR2 in Fujitsu Amilio Li 1718

by darrenforster99 / December 3, 2009 3:30 PM PST

I've got a little problem that I wonder if anyone can advise me on.

One of my friends has got a Fujitsu Amilio Li 1718 laptop, recently he noticed that the computer started to go really slow and his memory has gone down from 1Gb to 897Mb (???). At first I thought it was possibly the 128mb shared graphics, but in the BIOS you can increase the shared memory to 256mb and that doesn't make any difference in the amount of memory, so I presume some part of the memory has blown.

I have tried with CPU-Z by CPUID and that identifies that the memory is 1Gb but both BIOS and Windows Vista only show 897Mb.

Anyway we decided best solution is to upgrade the memory to 2Gb, he's running Vista Home Premium and 897Mb is barely enough to keep this system running.

I advised him to get two Corsair 800mhz 1Gb SODIMM DDR2 sticks. The current memory is one 1Gb 666Mhz stick.

After putting the two memory sticks into the computer and turning it on we got nothing but a blank screen. Put the old memory back in and it's fine, it still reports only 897Mb not 1Gb.

At first I thought it was possibly a BIOS issue so found an update, he was on Phoenix v1.7 and it's now updated to v1.9 but still nothing, the only thing this BIOS update claims to fix is the 897mb problem as apparently the computer reporting 897mb instead of 1Gb is known bug, however that didn't even fix that.

I notice on a few websites they mention all memory speeds up to 666mhz for this laptop but not 800mhz, but surely if the computer doesn't support 800mhz memory the memory will still run at 666mhz instead, on desktop computers this is normally the case, is this different in laptops?

I've also tried inserting the memory in one at a time and putting it in the different slots in case it's a defective slot or one of the memory modules is defective, but nothing, the memory does state on the back "Guaranteed compatibility"

Any help or advice to get this memory working would be greatly appreciated.

Don't over analyze this one.

Vista is already slow on 1GB so any small update to antivirus could cause it to go slower still. Think 3GB ram next time.

Walk away now while you can. This is one of those tar pit issues where you could lose far too much time over nothing but just too little RAM and "Vista".

Again, you can fret all you want over "where's the RAM" but Vista on this little ram will be a slug.

It's now fixed, turns out yes the laptop wouldn't take 800mhz memory, only 667mhz. Strange how it doesn't just slow the memory down to 667mhz though.

We took the 800mhz memory back to Scan computers in Bolton and they were really helpful about it, just changed it over straight away, and allowed us to use their testing area to install the new memory in and check it works, to save us another trip back out there.

The laptop is running super fast now.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
