Toshiba A135 S2276 memeory upgrade ??

i woud like to add 1 gig memory to the satellite A135 s2276.
i have a few questions though.........
does it have 1 stick of 523 ram.
I know it requires PC 4200 DDR 2 (533mHz) but how many pins does it have ?
what is the difference between 200 and 240 pins.

I got a good deal for 240 pin pc 4200, which i wanna buy, is it compatible with my laptop ??

Details: 1 GB PC4200 DDR 2 memory features 240-pin, 1.8V, CL4 and 8k refresh rate.

Specifications:
Memory Size 1024MB
Memory Speed 533MHz PC4200
Memory Type DDR2
Pins 240

 

If you have 1 GB of RAM at the moment, it is highly likely that you have two 512 MB modules installed. That means to upgrade to 2 GB in total, you will have to remove both the modules, and then install two 1 GB modules. The number of pins is very important. Your notebook only accepts DDR2 SODIMM 200 pin memory. The DDR2 240 pin memory is desktop computers, and is not compatible with notebooks. The main difference between the 200 and 240 pin memory is the size. Normal DIMM's are twice the size of SODIMM's.

 

hey zero,

thnks for the quote. sorry i was not very clear. I have only 512 mb memory installed in my laptop. I actually wanted to know whther this laptop has just a single card of 512 mb or both my slots are occupied with 256 each.

regarding the 200 pin issue i have no idea. i was quoting the ad given below. Thanks for the information !!!

No problem for the information.

Ah, if you have 512 MB, its more or less the same thing. You probably have two 256 MB modules installed. So, another 1 GB will help out, but you will have to remove one module, in order to install the new one. You should be able to confirm whether you have two modules by undoing the screws which hold the panel which covers the RAM. It should say how to do this in the manual of the notebook.

The RAM you have linked is desktop RAM, and it won't work with the notebook. Desktop RAM is cheaper than notebook RAM, because it is easier to manufacturer, because it is larger. I linked some RAM below that should have no problem working in your notebook.

Although the speed is 667 MHz, your notebook will automatically bring the speed of it back to 533 MHz, and it should have no trouble running in your notebook.

 

THNKSSSSSSSSSSS. that makes life much easier

 

No problem. If theres anything else that you don't quite understand, then just post back.

 

My a135-s2246 came with one 512MB SODIMM in it.
Several others on the forum has the same set up from factory.
Just open it up and check.

 

thanks man i will go ahead n d0 that

 

Through all the checking I have done. It seems that your model should have a single 512mb sodimm. If that is the case a very easy upgrade would be to just buy another 512mb sodimm.

 

hey votoms,

i was finally open the panel and check the memeory module and yipeeeeeeeeee its one 512 mb stick. but i still wanna buy a gig for the other slot. any deals ??

 

My Standard A135-S2276 came with one 512mb DDR2 rated at PC4300. Since the module is DDR2, one should use two memory modules with the same rating and size (ideally two of exact same type) to get the advantage of double data rate, thus, get 2 X 512mb or 2 X 1gb NOT 1 X 512mb and 1 X 1gb, otherwise, your system memory will not be running at full speed. Run CPU-Z software (first result of Google "CPU-Z") to get your system memory hardware info.

 

hello,

i still feel that 1 gig + 512 wud be quicker than only 1 gig. any opinions ? again i can later get another gig that way.

 

If you do upgrade from the current 512 MB to 1.512 GB, then it will be quite an improvement. Upgrading to 1 GB is also an option. Check in Task Manager (Hold Ctrl and Alt, and press Del) under "Performance", and have a look at high much RAM you are currently using. It is likely that you will be using quite alot of the Physical Memory. Normally, 1 GB is more than enough memory for the average user, even some heavy users find 1 GB in Windows fine.

 

The X200M mobo is not dual channel so matching sizes does not apply. The intel 9xx mobo's however are dual channel so match sizes on them. Double Data Rata doesn't mean dual channel. DDR2 explained Just means clocks on both rising and falling edges of the clock. Example if the clock = 266MHz then the DDR2 ram = 533MHz.

 

does ayone know how relace memory in 2276.

i am looking for a 1 gig pc 4300 533mhz stick........anyone has a spare one ?/////

even a chheap 512 one wud do !!!

 

How can you tell if your Motherboard supports dual channel? I have a 1GB 5300 667Mhz stick that I will replace with 2 1GB sticks if I can do Dual Channel. Otherwise I'm just going to buy a 2nd 1GB stick.

I have an A130 custom from the toshiba website with the Nvidia 7600 go Video card.

 

Decent deal on 1GB 667MHz ram here $68 shipped

To find out if you gots dual memory Mobo
Run CPU-z on your laptop and under the memory tab there is a Channel # field dual/single.

 

out of stock !!!

 

"Radeon® Xpress 200M provides investment protection for next-generation operating systems along with support for DDR2 memory up to 667 MHz. " from ATI website.

If I get a 1GB 667Mhz ram, would it runs at 667 or 533?
The FSB is 533Mhz, does the 200M lock the DDR2 bus speed to the FSB speed or does it have clock gearing to support running the memory bus at 667?

 

Cheapdude, I put 667Mhz in my A135-S2246 and CPU-z shows it running 333MHz asynchronus which means the Xpress 200 is handling the 667MHz at full speed.

I think if you have 533MHz it locks/syncs with FSB, but with 667MHz it run async.

 

slappin,
That's what I want to hear. Any speed increase is good.
Thanks!

 

The speed increase in terms of frequency, will gave no real gain in actual computing performance, because 533 MHz and 667 MHz perform practically the same. The 667 Mhz RAM has a higher latency value than the 533 MHz RAM, so it takes longer to access. But the frequency of the 667 MHz means that it can claw back some speed, so it performs the same as the 533 Mhz RAM.

 

Zero is right the latency on the 667 was higher cas went from 4 to 5. I'll post the CPU-z results tonight. I don't think there will be any real performance increase over 533 considering the CPU is still fetching the ram at 533, but I am going to try to stick a T2500 (2GHz 667MHz Core Duo) in mine on Thursday or so next week and will post my findings. Hopefully Toshiba was nice and used ATI RC410ME which supports 667 core duo processors. I am betting they only used ATI RC410MD. Fingers crossed

 

heh heh, I returned the 512MB 533Mhz DIMM and got a 1GB 667 DIMM.
$70 on sale at Fry's today.
The idle latency is the same at 7.5ns, but the bandwidth is much better.
I don't run benchmark, but if you can run some kind of stream benchmark you should see some differences. Remember the CPU is not the only consumer of the memory bandwidth.

I'm thinking the 667MHz increase would be helpful for the integrated gfx. I don't know the exact pipeline, but the graphic pipeline probably branch off the FSB pipeline at some point.

Anyway, my window experience index for Aero graphic went from 2.3 to 2.6.
Memory operation number is the same though - 3.9.

I'll sell the samsung DIMM that came with the a135 so as far as $$ goes, it's actually cheaper than getting another 512MB. Probably less heat as well with one stick.

 

Yes, you are correct. Integrated graphics will perform worse if they are paired with 533 MHz RAM and a Core Duo/Core 2 Duo processor. In that circumstance, going with 667 Mhz will mean that the integrated graphics will perfomr better, but the power of intgrated graphics isn't much anyway, so any difference will be small.

 

Ok, so I ran CPU-Z. On the Memory tab is says Channels # 1.

Does that mean that I only have one stick of RAM so it is running in single channel mode, or does it mean my motherboard only suppost single channel?

Thanks

 

As you can see in my image mine said single when I had 1 stick in, so I don't know "#1" may very well mean dual channel. GL

Mine is: A135-S2246 (ATI XPRESS 200)

 

I just bought a Toshiba A135-S2276. Does anybody test if it can run DDR2-667 or DDR2-533?

Did anybody tested if it can run dual channel memory?

Thanks

 

I have an s2276, and it came with 512MB DDR2-533 SODIMM. I bought a stick of 1GB DDR2-533 SODIMM, and just popped it right in. Works like a charm - 1.5GB, dual channel. I don't know if the number of free slots varies with each individual notebook, but that seems highly unlikely... You should check anyway. Meh.

 

Can two 512MB and 1GB work in dual channel? I thought only 2x512MB and 2x1GB were possible.

Did you try CPU-Z? Did it show dual channel under memory label?

 

It's recommended that two modules of the same size be used for dual channel (I think because this was only possible in the past...? someone check me on this..), but it is possible to have two modules of differing size.

[Edit] Got something from Wikipedia:

[Edit II] Hm. CPU-Z is reporting single channel. Interesting.

 

I am 95% sure you are correct in that they need to match.

 

I currently have one OCZ 1GB DDR-533 along with the samsung 512MB DDR-533. First of all the CPU-Z 1.39 cannot identify OCZ 1GB DDR-533. Second, it shows "Channels #: Single" under "Memory" label.

I wish to try dual channel. I will either sell the 512MB and buy another 1GB, or sell both and buy a dual-channel kit. However, is there anybody get a CPU-Z verification that Toshiba A135 S2276 do support dual-channel memory?

 

With the new Intel chipset, there is no need to match the memory exactly. Different densities can also be used, as the memory should still run in dual channel. If you do use different densities, then the memory runs in asynchronous dual channel. If you use the same modules, then it will run in the full synchronous dual channel.

Dual channel doesn't have much of a performance difference at all. In memory intensive applications, the difference is still very small, and certainly not worth the trouble of having to find two matched pairs, particularly, as they are often more costly than purchasing two simple modules.

 

hello,

I wanna buy a 1 GIg for my toshiba A135 s2276. it has 512 mb RAM module in one slot. I am thinking of buying corsair 1GB DDR2 PC2-5300 667MHz 128Mx64 200-Pin SO-Dimm.
my question is, will this one work on my motherboard, especially since its density is 128m x 64 ??? i dont know anything about the density stuff...plz advice.
the 128m x 64 module is supposed to be super fast. Ok another thing my notebook can be upgraded to 2 GB
thanks in advance

 

A135- XPRESS 200 IS 667MHz DUO CORE COMPATIBLE!!!!

I purchased a T2500 2.0GHz Core Duo off Rapebay.

Installed it today in my A135-S2246 Celeron 430 1.73Mhz.

BAM BOIS show 2.0GHz Core Duo on boot.
BAM the CPU-z shows bus is up from 133MHz to 166MHz
CPU-z shows the Core Duo running full 2.0GHz

Bottom line <$500 a Core Duo 2.0Ghz running 667MHz FSB & 2GB DDR2 667MHz

I can't believe it! I can't believe it! I can't believe it! I can't believe it!

Please can you not double post. Thanks

if you want to upgrade, then you need some 200 pin, SODIMM DDR2 RAM, with a speed of 533 MHz or 667 MHz. Don't worry about how the memory is arranged. So long as you buy a module from a good reputable brand, like Corsair, Kingston, G. Skill, then you should have no problem in buying compatible RAM. Hope this helps.

 

thnks man zero,

infact i didnt wanna double post i wanted to quote but it got double posted. hey slappin did u get the laptop for free?
s2246 = atleast 350
2 gb ram = 140 ~
dula core = 200 ~
total =700 ~

 

I borrowed my friend's new G.Skill DDR2-667 2 x 1GB Dual Channel kit and installed them on my Toshiba A135-S2276 laptop. The CPU-Z result is very very DISAPPOINTING!!!

It shows the both Single Channel and Asynchronous!!!!
So I guess it means Toshiba A135-S2276 does not support dual channel memory!!!

 

Please dont tell me that!!! I have the newer version of the a135-s2276 with win vista and Please God I hope it will work Dual Channel. If you are making up a lie please dont! God ******!

 

does any1 know with which brand of RAM, a135 2276 comes with?
i have 512 and i want to buy 1 stick of 512 more.which brand should i buy??

 

I believe the brands installed will vary, and they are normally cheaper ones. if you are looking for new RAM, try and get RAM from reputable brands, such as Corsair, Kingston, Crucial, OCZ. There are other good brands aswell, but they seem to be commonly found. Cheaper bands should also work, so if you are on a bugdet, you could go for them,but I have noticed the price different between the brands isn't too great, generally.

Also, check and make sure you have one module of 512 MB installed in the notebook now. You can do this via means of softare, by using a program called CPU-Z. It will tell you how many modules of RAM are currently installed. If you are certain you have a slot free, then you can skip this part.
