I have an Emachines T1110 desktop with an Anaheim-3 Rev. F-motherboard that came supplied with a 168 Pin 256 Mb, PC133 memory module. I recently purchaced another PC133/256 and installed it into my motherboard. My machine does not boot up with it. I switched the modules around putting the new module into the first slot with the same results. The New module is good as I ran it alone and all worked fine. My question is: What must I do to get all 512 Mb to work in my system? Do I need a newmotherboard? Or, do I simply upgrade the bios? Thanks in Advance.

I do not have experience with E-machines, but it looks like you have two incompatible memory modules. No, you don't need new motherboard or upgrade of BIOS.

You need a memory module that is compatible to the one that was supplied with your system.

If you can return the memory that you purchased, please do so by telling the merchant that the module is not compatible with your current module.
You maybe able to ask them for the correct module by telling them what you have.

When gettinga new memory module, it is always recommended to know about your system or look up your system manual for upgrade information.

Some memory modules are only compatible to certain chipsets. Be sure of what you are buying for upgrade.

Hope this helps,

If the PC gets through the POST test, and simply does not boot into Windows, you may be running into the 9X/Me large RAM bug.

Windows 95, 98, and Me have a bug where they can have all manor of strange problems with more than 511MB of RAM.
This bug is VERY configuration dependant.

If you are running XP or W2K, you should not have that problem.

If you are not getting through POST, then answer 1 is correct, and your 2 memory modules are not compatible.

Another possibility, is that themotherboard has some memory limits, and cannot run 2 256MB DIMMs.

To identify RAM options, go to either www.kingston.com or www.crucial.com and see what RAM options they offer for your system.

I've come across this similar problem with an MSI6366 P3 motherboard. The mother has 3 dimm slots of which I had 2 256 sticks working fine. I purchased another 256meg stick of the same make and the PC would not post. After some research, I came to find out that the banks slot 1 and slot 2 supported double sided ram, the third slot would only work on single sided if the first two slots had each a double sided stick. I RMA'd the ram and purchased a single sided dimm from another make and it works fine.
Consult your motherboard manual if its available or d/l it from your PC maker's website. Check the specifications of the dimm slots.

Also a lot of the RAM supplied in e-machines units is DDR Type RAM...Are you sure you went to the e-machines website, entered your model & ser. # before ordering the new RAM?

Never say sorry for trying to help. I appreciate your time and energy. It is confusing even to chip makers. Emachines even has it PC100 for the model T1110 on the main page and PC133 on the upgrade page. They don't say, but they supplied two different motherboards for the same model, 1 for the 128 MB/pc100 and another for the 256 Mb/PC133.

Found the following on that site;

"Max Memory @ 256Mb on T1110 or is it?

I recently purchased an eMachine T1110 w/256Mb RAM and XP pre-installed.

Upgrade #1:

I successfully added a second hard drive.

Upgrade #2:

The machine came with a single, 256Mb stick of RAM. I attempted to add a second 256Mb stick. Upon reboot, I got a stop error related to ACPI ((0x000000A5). I tried swapping the sticks and got the same blue screen. I put in only the new stick and it booted up fine. At this point I poked around the SETUP screens and briefly considered the BIOS updating option recommended on the blue screen, but quickly decided not to risk it at this point. After some discussion with others, I tried one more experiment: in case the sticks were somehow conflicting with each other, I purchased a second, identical 256Mb stick from the same place. I put in the two identical 256Mb sticks and still got the same stop error. This is where the human machine did a "stop". Maybe others with more experience and nerve will find a simple solution to this, but I decided to shelve it for now.

Addendum 12/20:

Well, my obsessive nature paid off -[added an additional 128Mb stick to the already existing 256Mb stick] it worked immediately! I now have 384 Mb in my T1110 (anaheim-3). Unfortunately, the conclusion can either be: 1) 384 is OK but 512 is too much, or 2) The brand of memory made the difference. Although both this and the previous (failing) memory were nominally the same(133), there may have been some tolerance difference that made the previous memory fail - this would be my guess.
So it looks like the limit may indeed be 512Mb, like other's have discovered with other eMachine models. But, what do I know? I'm at least happier now.

Also do a lil comparison of your 2 memory modules to the following & see if they are matching.

Anaheim-3 Memory Support

The motherboard has two, dual inline memory module (DIMM), minimum 16MB to maximum 256MB memory size. The BIOS can automatically detect the memory type, size, and speed through SMBUS interface between the core chipset and DIMM module.

The motherboard supports the following memory features

? 3.3V and unbuffered168-pin DIMM
<3.3 volt has 2 notches "1 centered & 1left">
<5.0 volt has 1 notch centered>

(The chart wouldn't transfer here)see;
http://www.e4all.info/motherboards/anaheim3_memory.htm

DIMM Size Non-ECC DIMM Size Non-ECC
8MB 4 * (1M x 16bit) 64MB 8 * (8M x 8bit)
16MB 8 * (2M x 8bit) 64MB 4 * (8M x 16bit)
32MB 4 * (4M x 16bit) 128MB 8 * (16M x 8bit)
32MB 2 * (4M x 32bit) Single or Double Type support

I just tried this in a frriends/customer's emachine w/ an Anaheim-3 Mobo...He also was told that it maxed out @ 256MB of RAM, he was highly surprised that my cheaply offered stick of 128MB PC133 Unbuffered 3.3V Ram added in & posted right up and improved performance right away. (BTW, he said to thank you!)

He has WIN98SE loaded and can only actually use 384MB total due to the 98 glitch anyway so he's more than happy, also tried going up to the 512MB mark using a matching Unbuffered 3.3V 256MB stick, same result as yours & others...No Post Up. Looks like 384MB is max for that board my friend.

Might also want to get a hold of this guy thru that site listed above also...Looks like the CPU & BIOS upgrade are key to 512MB upgrade on that mobo maybe?

Wow!!!!That is quite an answer and a whole lot of research you did for me. Thank you very much for this. I haven't checked the site you sent me yet, but you gave me enough research to cover it. I also considered very much upgrading my bios, but when I did a little more research I found that the chipset is IntelWhitney. That is not a bad thing as many chipmakers are copying the Whitney, but on this particular model of computer, which by the way has a PheonixBIOS 4.0 release 6.0, has too manyvariations and to large of a margin for error when I try to download the correct upgrade for this. I have a friend who also advised me to go with the extra 128 stick. I guess 384 will do until I decide to buy a larger processor. Problem is, this model isn't cheap to upgrade since the motherboard is integrated, so when I change it I will need another integrated board. I don't believe there is enough expansion space in this particular case to go too far. This is just the beginning. TomorrowI will put in my 120 Gig Western Digital Caviar. Wish me luck! Thanks again for all of your hard work for me.
