How much maximum RAM can be supported in Laptop LENOVO THINKPAD E530 3259T2Q

[rajmehra300]

Hiiii,

I am in need to upgrade RAM of my laptop LENOVO THINKPAD EDGE SERIES E530 PART NO. 3259T2Q.Currently it has 4GB (2 x 2gb).

I am not sure how much I can expand RAM Memory upto?

As of now I have tried some of the scanner (memorystock.com ,www.crucial.com ) present online and also scanned my system with softwares like CPUID CPU-Z, AIDA64 Engineer, AIDA64 Extreme which all says I my laptop supports MAX MEMORY upto 16 GB.

I have done a lot research on web but official document from Lenovo contradicts with the scanners results as Lenovo says it supports max upto 8 GB only.

Please suggest on max RAM supported for my Laptop.

16gb!

Maximum you can get is 2x8gb of DDR3 1600 (or DDR3L) , for a total of 16gb

Currently the maximum you can get is 2x16GB of DDR3 for a 2 slot system giving 32GB of RAM if the hardware and probably more importantly the BIOS supports it.

My laptop have Processor – Intel(R) Core(TM) i3-2328M CPU @ 2.20GHz, Chipset- Northbridge:Intel Sandy Bridge rev. 09,Southbridge Intel HM77 rev. 04, BIOS Properties:Vendor LENOVO Version H0ET94WW (2.54 ). Will it support 2X16 gb?. I think 16 gb is max which can be supported. Please suggest further on this.

Hi All,

As per the suggestion as of now, I have understood that Chipset/CPU can support 16 gb but it is the motherboard/bios which can restrict it to support max 8gb as specified in the official documentation of e530 by Lenovo.

Is there any to way check max RAM support in specific with BIOS version/motherboard?

Usually Intel specifies memory that has been tested with a subject to change clause and manufacturers follow this even sometimes crippling the BIOS preventing support of higher densities. As time goes by and higher capacity and / or speed memory modules are produced the Intel specs remain unchanged perhaps because of cost of re-validating.

You can possibly mess around with SPD to simulate a higher memory size and see if the BIOS posts and accepts it or check BIOS code but given the above links looks like it should not be a problem. First site has guaranteed it works.

Can you please guide me how can I check SPD to simulate a higher memory

Usually just increase the column count, density and correct checksum. Then boot to BIOS with just one modified module as you don't want the OS trying to use non existent memory or possibly patch the E820 table. If it doesn't work then the unmodified module can be used to boot and the modified module hot plugged in the empty socket which should be isolated since it was not populated boot time but the I2C can be used to reprogram it.

It will vary from one model to another and some may be write protected in which case if it's only reversible protection you'll need to program it externally usually with A0 at 7V and use CWP command but you would need to check the specific datasheet for your SPD chip. The chipset can sometimes lock write permission too which requires a BIOS mod.

If you are really worried it will not work just buy from the "guaranteed" link provided and get a refund if it doesn't work or if buying from a local shop take your laptop with you and ask if they will test it first before buying.

I doubt that it will work, according to other forums, the 16gb ram modules do not work with any thing below broadwell .

Someone need to test it more, but for now, the only thing that is known to work is 2x8 gb.

They do work with Asus X79.

Yes, needs testing. From a few BIOS for IVB and HSW I have looked at there are limitations to prevent 16GB modules posting but at over $300 a module there's not too many people willing to not only test them but also modify the BIOS firmware.

I was talking about laptops when I said "16gb ram modules do not work with any thing below Broadwell" ,
and that is according to some forum post on notebookreview's forum, and they didn't even mention if they were tested on M or U series proccessrs.

They should 'theoretically' work with Ivy brdige and Haswell M-series processors, since they officially support 32 GB of ram.

As you say, $300 is too much to spend for one module, from a not very famous brand, when you could better of getting a laptop with 4 ram slots to put 4x8 if you really need to.

This is a rather benign topic that shouldn't develop many misunderstandings.

I have concluded -- deduced -- reviewed that there is an industry practice, more or less pervasive, in which laptop mobo-makers write a specification for maximum RAM according to the size of a single module.

I worked my way through this little mystery last year. I acquired a custom-configured (to my specs) ~2007/08 "Executive-class" laptop last year -- A Gateway E475-M -- and I refurbished it with an SSD and replacement-upgrade for 2x1GB. I made the mistake of ordering a 2x2GB kit of SO-DIMMs, because the archived Gateway specs were "4GB," with no individual spec for a module -- maybe the QVL list -- but the list itself may be lacking in enough detail to make it "undetermined."

I researched the motherboard in more detail, and then gambled -- yes, gambled -- that a 2x4GB kut would work with that old T8500 C2D Centrino. It had been much clearer from the git-go as to the possible option of upgrading the wireless-G to Wireless-N -- the extra antenna -- was already fitted to the laptop innards.

This trouble was all a result of my confusion in interpreting the laptop-maker's specs for RAM.

Moral of the story: live and learn. And -- this old laptop dinosaur really gallops.

With an IvyBridge i7-3770k using 4GB modules with columns increased from 10 to 11 and density to 4Gb to emulate 8GB modules. Remapping disabled and top 8GB reserved everything seems to work okay or as expected.

Increasing columns from 10 to 12 and density to 8Gb to emulate 16GB modules however results in addressing wrapping around at 1GB. To boot into windows TOLUD needs setting to 1GB and all memory has to be reserved above 4GB resulting in only 480MB for the system.

This happens even if using 8GB modules with 16 rows and column addressing increased from 10 to 11 to emulate 16GB modules.

Adding real 8GB modules with the 16GB emulated ones does not help with the address wrapping problem.

Seems like a hardware bug with addressing using the larger densities. All hardware registers appear to be set correctly unless there is some undocumented setting not in the public data sheets that I am missing. Do remember though Intel have specified 4Gb maximum density.
