I am trying to upgrade to 8GB of RAM in my trusty old T500. I bought 2x4GB G.Skill sticks that appear to be compatible in every specification. Here is the riddle:
1) Both sticks are rejected when inserted into the lower slot. I get a 1-3-3-1 beep every time.
2) One stick works in the upper slot with the original 2GB stick inserted in the lower slot. I ran 6 passes of Memtest86+ on this configuration without seeing a single error and the computer is clearly using all 6GB of memory after booting.
3) The other stick will not work in the upper slot with the original 2GB stick in the lower slot and even Memtest86+ freezes with this configuration when I am able to boot at all without getting a 1-3-3-1 beep at power-on.
It seems clear that one of the sticks is bad. I am at a loss as to why the other stick will work only when paired with the original stick and only in one particular configuration. The BIOS has been updated to the lastest version, 3.23.
At one time, both of the new sticks would work individually when inserted in the bottom slot with nothing in the upper slot. However, this was always inconsistent and neither one has worked in that slot since I disabled fast boot.
My best guess is that some setting is being read from the old 2GB stick when it is in the lower slot that also works for the one good new stick. As to what that setting might be, however, I am completely at a loss as the specs for the new and old memory appear to be identical.
If the one good new stick won't work in the lower slot, replacing the bad stick won't get me up to 8GB as I seem to need that old 2GB in the bottom slot anyway.
Advice is appreciated.
Solved! Go to Solution.

HMM: page 91
The bottom slot must ALWAYS have memory in it.
The top slot is for additional memory.
The bottom slot should contain the largest memory stick.
If both new memories beep in the bottom slot, an issue exists.
What are the part numbers of the new memories?
Please take a picture of each label on each stick.
With the old 2GB in bottom slot, post screen shots of CPUZ SPD and Memory tabs.
Page 98 of HMM discusses Intel Turbo Memory minicard. Does your machine have this?

Hi. Thanks for engaging.
From the stickers:
Samsung: 2GB 2Rx8 PC3-8500S-07-10-F2 G.Skill: F3-8500CL7-4GBSQ
I haven't found anything for Linux as good as CPU-Z. Not sure it's possible to get any more information than lshw anyway, which shows:
*-memory description: System Memory physical id: 2b slot: System board or motherboard size: 6GiB *-bank:0 description: SODIMM DDR3 Synchronous 1066 MHz (0.9 ns) product: M471B5673EH1-CF8 vendor: Samsung physical id: 0 serial: 48196F66 slot: DIMM 1 size: 2GiB width: 64 bits clock: 1066MHz (0.9ns) *-bank:1 description: SODIMM DDR3 Synchronous 1066 MHz (0.9 ns) product: F3-8500CL7-4GBSQ vendor: Fujitsu physical id: 1 serial: 00000000 slot: DIMM 2 size: 4GiB width: 64 bits clock: 1066MHz (0.9ns)
Both brands are unbuffered but I just noticed that I-Nex (a really lightweight CPU-Z alternative for Linux) is showing 115MB of "buffers."
I am quite certain I do *not* have a Turbo Memory Minicard installed. Don't see it in either lshw or I-Nex and have never even heard of it in all the years I've owned the trusty old T500.
Yes, it would seem that the G.Skill memory is just not compatible with the mobo. But I would like to diagnose the compatibility issue before exchanging them, if possible, rather than any more trial and error.

I noticed that but wasn't sure what to make of it.
I bought the sticks from a reputable store, the packaging says G.Skill, and so does the holograhic portion of the sticker that's on them.
Do you think they are mislabelled?
(Wasn't implying you were engaging in trial and error. Just explaining why I am futzing around with memory that is clearly incompatible. And by trial and error I meant exchanging and installing other memory without a diagnosis -- not this kind of troubleshooting.)

Supply CPU-z snapshots.
I do memory help all the time.
User in UAE with G50-70 got beeps. Original works, add new fail.
ORIG, from 2012, was version B.
New was ? version A.
Vendor, Hynix, discontinued version A in 2015.
I showed user Amazon USA still selling version A.
Bottom line, user memory new is DOA, manufacture, prolly 2008? Before his machine ever offered for sale via lenovo.
You have the same issue, but I need screenshots from CPU-z..

Can't run CPU-Z unfortunately. The T500 is running Linux and the memory is incompatible with my Windows box. The best I can do at the moment is to add some output from dmidecode:

The Part Number for the 4GB "G.Skill" is the same as what's on the sticker.
I appreciate your help.

Your new memory sticks are indeed G.Skill and match your machines memory spec.
Passmark tested this memory July 2015.
Your OEM Samsung memory:
 There is a difference in the CAS tick marks between Samsung and G.skill.
Usually this is not a issue.
Your best bet is to return to seller and try a different brand. I always use Crucial memory.
Crucial states 1.35V memory... but they often sell dual voltage memory.
. Your new memory is probably defective as you have suspected.
I cannot verify "birthdate" of memory in your DMIdecode output vs CPUZ.
