Does anyone know if it's possible to put more than the 4GB allowed into this PC

Does anyone know if it's possible to put more than the 4GB allowed into this PC?

Lenovo ThinkCentre M90 eUSFF (3244-A9G)
Chipset is: Intel Q57

It says that Maximum internal memory is:
4 GB

Memory clock speed
1333 MHz

Memory slots
2 x SODIMM

Will it definitely not work if I put there 8GB of RAM?

According to this it will support 8gb of ram.

it may come with 4G (which is what they mean by max), but it might support you adding more to go up to 8G or even 16G if you're lucky. assuming you're not using a 32bit OS in which case 4G is all you would have access to anyways...

giantbucket :

It came with 2GB actually

It is 64 bit.

Should I risk it and get 8GB?

jimpz · Mar 18, 2015

The link I posted says it will support up to 8gb

Hm.. interesting, because according to this and this it's 4GB max:

Actually if on your link you go to Specifications it also says there MAX 4GB.. this is beyond confusing now

whatever61 :

if the store will let you return it on the off chance it doesn't work right, then i'd say yeah go for it. from what little i've seen, "supported" tends to mean "we [Lenovo] tested it up to X", but Win itself will typically happily support more than what they tested.

whatever61 · Mar 18, 2015

Yes, I know that this is often the case, that's why I opened this thread

Anyway, just to verify another thing: the max ram supported depends on the chipset, right? so seems like Q57 supports up to 16GB!
Or there can be something else involved also?

giantbucket · Mar 18, 2015

the CPU has the memory controller, not the Q57 chipset.

This link is from Lenovo's web page & has 8gb listed (I hope they know what they're talking about) ;-)

When it comes to OEM's, the bios of a motherboard can override any hardware. . .

CPU seems to have also 16GB limit:

I suspect "eUSFF" means it's the "Eco USFF" model...which is significantly smaller (far left in the picture at the bottom of the 2nd page) & only has 2 DIMM slots vs. the 4 of the other models. Which probably means it's limited to 4GB (2x2GB).

The question is whether yours has a single 2GB stick or two 1GB sticks. If it's the latter, you'll need 2 new sticks to get to 4GB; if the former, you only need 1.

whatever61 · Mar 18, 2015

spdragoo :

I have now 1 stick of 2GB and 1 stick of 1GB.
But it's not important what I have now. I can replace everything and put 8GB with 2 x 4GB sticks, if I would know that it would work..

sorry, missed pasting the Lenovo support link last time!

Show 8gb

whatever61 · Mar 18, 2015

This model is in two places and every time with different specs:

http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m90/documents/PD002723?tabName=ProductParts

http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m90/documents/PD004713?tabName=ProductParts

In both cases it's M90 and in both cases 3244 is one of the models...

whatever61 · Mar 18, 2015

I suppose the first one is the more general one (it has different setups and not a specific CPU) and the second one's are more specific one and there it says that only 4GB is supported

spdragoo · Mar 18, 2015

Well, as the product information sheet points out, as well as some other links (http://www.eweek.com/c/a/Desktops-and-Notebooks/Lenovo-ThinkCentre-M90-M90p-Desktops-Tap-Intel-Core-Chips-804884 , http://www.pcmag.com/article2/0,2817,2368962,00.asp , http://www.silentpcreview.com/lenovo-m90p), it looks like there are a multitude of models:
-- 1st difference being the m90p vs. base m90; the "p" is meant to be performance, so I'd guess that the base m90 is the one with the Pentium or i3 option (see the product sheet link in my prior post)
-- 2nd difference being the form factor of the case: there's a "tower" version (44.2x17.5x41.4cm), a "desktop" version (35.5x31.7x9.9cm), & the "Eco USFF" model (23.8x27.5x7.9cm).
-- 3rd difference is in the boards: the Eco is specifically listed as having an "ultra small" form factor. The tower probably uses something close to a mATX board (2 PCI + 2 PCIe slots, x16 & x1), but the desktop is definitely smaller (1 PCI + 1 PCIe x16, both low-profile), & the USFF even more so (1 PCI low-profile -- yes, that's right, no PCIe slot, not even a x1).

To me, the biggest issue is the external "power brick". That & the carrying handle on the case is meant to make you think it's portable, I suppose...although you're still lugging the monitor around as well.

whatever61 · Mar 18, 2015

Well ok, but I provided the specific model..

spdragoo · Mar 18, 2015

Then, I'd say you can't get 8GB in it, because the 3244 is the lowest model # of the Eco USFF type for the m90...and the Eco models have only 2 RAM slots (instead of the 4 on the Tower/Desktop models). With the apparent limitation of 2GB per slot, that puts you at 4GB max.

Does anyone know if it's possible to put more than the 4GB allowed into this PC
