Note: Can all owners of the MPC1000 who have upgraded with non akai branded RAM and CF CARDS please post the Brands you own so that we can compile a list of whats good and whats not.

Also as a disclaimer, "WE as users RECOMMEND but do not ENDORSE you to purchase these brands for we will not be responsible for any damages you or the product causes"

This is mainly for newbies who need serious advice!

I my self have installed:

What you need to concentrate on is PC 133 144PIN CL3 SODIMM 256MB.



You ask why 256MB?

The Ram is 64x4. meaning it has 4 banks of memory that are 64MB's Each
The MPC1000's hardware structure only can read one side of the ram chip or two banks if I'm not mistaken, (someone hear can confirm the right reason) anyway.. it will only read half of the Ram so there fore if you use 128 only 64MB will show up on your MPC1000. This is why we use 256MB so that 128MB shows up. Now dont complain about 128MB cause thats the max the MPC1000 deals with. So dont buy 512MB!

Now why do we buy it? cause its cheaper to buy 3rd party Ram than Akai's ram. Akai charges 3 Times the amount for their ram which is still 3rd party ram made by 'Hynix' which is ironic to say the least in my situation, though I got mine out of a second hand laptop in a compuuter fair. So do the math. Pay $99 or £99 for 128MB of Akai ram when in some PC stores $99 or £99 can buy you 1gig or more of ram!! erm...I think not akai!! so why not buy a well known and trusted Brand Like Kingston and install that instead for $45 or about £30-£40 of 256MB.

See the sense now?

CF Card I use is Dan Elec 2GIG CF TYPE I Card. Purchased from

I have PNY 256mb pc133 144 pin sodimm and sandisk 64mb, 512mb and 2gb CF, kingston 128mb CF.

To add to what Penfold said, try $149US for the Akai brand 128mb mem chip. and now, you can get a Sandisk 1gb cf card for only $79US

Penfold, you are correct in principle the mpc1000 only utilizes half the bus of the mem chip thus only able to see 128mb out of 256mb.

I co-sign Penfold with that disclaimer

so if it can olny hold 128 y buy a 256 instead of a 128 im so confused please to beat me for asking

read exactly what Penfold wrote on why.

ok listen. older mpcs take a single bus memory chip SIMM (single inline memory module) the mpc1000 was not built like that. for some reason akai made the 1k to take dual bus memory chip DIMM (dual inline memory module) but it only utilizes half of that. I think they did it like that because no one uses and barely manufactures SIMMs anymore so they had to use updated technology, DIMMs. also, when you have a computer that use SIMM mem chips you have to buy two so to get 128mb you have to buy two 64mb chips. you also have to think about this: the 1k is smaller than all other mpcs and they probably didn't have the room to fit 2 standard size mem chips (another reason why they went this route) the SODIMM memory is standard laptop memory and it fits somewhat on the outside of the machine (not directly on the motherboard).

so with all of that said. In order to take advantage of the capacity of 128mb that the mpc was built for, you have to get 256mb. it will not work with 512mb to get 256mb, like penfold said. so don't try.

hopefully this cleared up some things for you.

I have a SanDisk 2GB CF. I am currently using the Akai 128MB memory, but bought the kingston 256MB. I will be returning the 128 Akai **** for a trade or refund, paid $120 for it.

Funny thing is, if i am not mistaken. the Akai 128MB ram has only 2 chips on it, not 4. Also, I tried adding a 512MB chip from PNY and the boot loader started and stated that there was 256MB but when it ran through an error check the memory failed. But the unit was able to read half of the chip like what was stated in the first post of this topic. Maybe a future release will allow for larger RAM sizes. comon Akai, dont hold back, get those programmers on the ball.
