Advent 7555gx ram queston

hi guys i a few months ago 6 exactly i bought the best laptop i ever had its called advent 7555gx and win 7 x64

this laptop is used like a prostitute working day and night at 65 % cpu load i have made for it custom cooling not cuz it was overheated but cuz i wanted to make the cpu stay at 30 to 40C max and it does.

till today i only had an issue with optiarc dvd it stopped work.

the question is i have 4gb ram and cuz i use applications Adobe exactly which instead using hdd use ram to store whole data render etc i would like to upgrade ram dont know if it is possible if the motherboard and socket support 8gb and if bios does.

i dont know if i have ddr ddr2 or ddr3


could please soemone advice me a bit? tnx

other question

does somewhere in the world exist device that i could use as an externeal ram base and connect it to the pc laptop etc trought sata pci etc?

 

You won't be able to add RAM externally, but download CPU-Z and see what you have installed already.

See:
CPUID - System & hardware benchmark, monitoring, reporting


When you have some info (screen shots are better), come back and let's see what your system can support.


If its like this:

See:
UKT Support - Advent 7555GX Laptop


Then you **should** be able to upgrade to 8GB DDR2 RAM.

But see what CPU-Z tells you first.

Good luck.

 

thx for your replay

i checked the web you showed to me and yes it is exactly i think the same laptop

please see attached cpu-z output pics

i know i have ddr2 installed i have question if i buy DDR 3 will it work on my laptop ?

second do i need upgrade bios or anything ?

should i buy any special ram what manufacturer ? or just any 2X4gb ram will work ?

tnx

 

From what I saw, the Advent 7555GX is a rebranded MSI GT725 for the UK market. The MSI GT725 supported a maximum of 4GB of RAM (2x2GB configuration).

I cannot find any additional information about the Advent 7555GX, such as a manual or specifications. So unless someone has some other infomration, I would have to say no - you cannot upgrade your memory beyond the 4GB that you have now.

 

First, thanks for the pics!

Second, DDR 3 cannot work in a DDR 2 memory socket (simply won't fit and even if forced, different electrical signalling).

Thirdly, you should upgrade any BIOS or firmware you can find for your notebook. Your BIOS for example is from Dec 10, 2008, so a newer version may be available. You should do this even if you don't get the RAM (many fixes and optimizations are made available on newer BIOS's without the manufacturer stating what exactly was fixed - or why).

Now, does your notebook have the abilty to handle 8GB of RAM? I'm not 100% sure, but according to the chipset inside (as reported by CPU-Z), yes, it does support up to 8GB.

See:
Mobile Intel® PM45 Express Chipset


Note that there have been a few models that never did officially support 8GB RAM, but when tested, they worked fine (with a 64bit O/S of course).


Finally, as to the question of 'brand' of RAM: get the cheapest RAM available from any manufacturer that offers lifetime warranty on it.

If you are able to purchase with a 100% no restocking fee return policy, you will be able to test for yourself if your specific model will support 8GB of RAM or not. If it doesn't, then that must be BIOS limited from the manufacturer and I would go looking for a custom BIOS for your system (if such a BIOS exists).

Before you get rid of your original RAM, be sure to run multiple instances of memtest at least overnight if/when you do get a chance to test with new RAM in your system (I usually leave new systems/new RAM modules testing for over 24 hours before I can begin to trust them with my work/data).

Good luck.

tnx for your anser

i have Advent it work great but Advent mean Pcworld so no support esp about BIOS. i heard people used MSI to upgrade their Bios on 7555. and now few things MSI say gt725 work max to 4gb second i think PC world Bios for Advent is custom made. originally this bios come from American megatrend but companies like MSI or PC world change things in it before they sale whole laptop to a client. there is none bios to upgrade from the so called TECH guys there is bios i could get from MSI and AMI.

but where to go and what to get and the last is it worth of risking ?

i coulld kill my motherboard cuz never did it before.

if my motherboard and the cpu does support 8gb of ram. will the bios i got at the moment work with 8gb>? and if i upgraded what bios should i get ?

there is none from PC world
one from MSI web for gt725 not sure if will recognisse 8gb of ram and if it will work
and i could use AMI bios. the same dont know if it will work they say only for motherboards purchassed from Ami and only for motherboards that already include AMI bios.


i just checked the bios info from under bios screen it says :

Bios Build A1722IDI ver 1.0 P 2008
EC Build 1722EDI 1 ver 4.30 2009

and on the bottom of the screen it says American Megatrend v 02.61 AMI

sign directly on the Motherboard i checked it too says MSI

when i boot system up on the screen i get Advent Logo

so i dont really know who make build etc the bios i use.

do you know what EC build 1722EDI 1 ver 4.30 2009 mean ????


last question im planning to buy this one DDR 2 4gbx2 Kingston http://www.saverstore.com/product/2...R2-Non-ECC-CL5-200pin-SODIMM--Kit-of-2-x-4GB- do you think it is good choice ?

 

The amount of RAM that is supported is not entirely a BIOS issue... in most cases, you cannot just flash a BIOS and have it magically support more memory. Your motherboard chipset and the memory controller on your computer needs to also support it, combined with a BIOS update.

Can your laptop support 8GB of RAM? Most likely not. As I've mentioned before, the specifications for the MSI GT725 (the closest make/model to your laptop) only supports 2x2GB. You can certainly try putting 2x4GB in your laptop. But be aware that there's a pretty good chance it will not work, and that you will be stuck trying to get rid of 2x4GB.

 

kent1146,

the link I provided a couple of posts above does suggest that his chipset supports 8GB RAM.


FluxAeon,

First, that link you supplied is for RAM slightly slower than what you have right now. Since you're using Adobe products you may see a speed difference from how your system responds now to how it will respond with the slower modules.

Try to find DDR2 PC2-6400 RAM (same as what you currently have) to give you the best chance of the RAM working in your system. As to the price, I'm not sure what is 'normal' for your area - but it does seem to be somewhat fair (just guessing!).

Also, do you have (no fee) return priviliges with that supplier? Just in case it doesn't work?

As to the BIOS situation, sorry, I can't help there at all. Too many variables and I'm not familiar at all with your system.

As long as you can return the RAM without penalty there is no risk in trying the RAM out (even if it is slightly slower, the motherboard will simply downclock itself to match the RAM installed). At the worst you won't be able to boot - or, if it gets past the boot stage, your O/S will be unstable (this is why you must test it via memtest).

Keep in mind though that when you are switching the RAM modules; do a full shutdown (not a sleep or hibernate) and unplug the computer from the power supply. Take out the battery and then exchange the modules.

I would try a single 4GB module first (make sure you try both ram slots - it may only boot from a specific slot with a single module installed) and if that works try booting with both (or with one new 4GB and one of your original 2GB modules).

And one extra warning: be especially cautious with unknown BIOS's - a working (but slightly limited) notebook is worth more than the mere potential of a better notebook with a simple 'flashing' of the BIOS - that can leave your system dead.

Good luck!

 

According to this it does. http://forum.notebookreview.com/msi/410822-advent-7555-gx-msi-gt725-again-35.html#post5883409
