Revision as of 15:35, 22 June 2007

Some ThinkPads are known to support more memory than their specs say. This page gathers information about those models, how much memory they can take and what special requirements that memory must fulfill.

Have a look at the Memory page for the official memory configs and partnumbers

Tested Memory configurations

The following table gives an overview of tested memory configurations that exceed the specified limits for that ThinkPad type.

ThinkPad max. Specs BIOS Embedded Controller Memory configuration successfully tested
ThinkPad A31p
2653-R		 1 GB 1.09 1.05
  • Kingston 1GB 200-Pin DDR Model # KTM - TP9828/1G
  • Kingston 1GB 200-Pin DDR Model # KTM - TP9828/1G
ThinkPad T30
2366-92U		 1 GB 2.08 1.06
  • Kingmax 1GB 200-Pin DDR SO-DIMM DDR333 (PC2700) Model # MSAD42D-KI
  • Kingmax 1GB 200-Pin DDR SO-DIMM DDR333 (PC2700) Model # MSAD42D-KI

but see problem with T30 not booting with 1 GiB memory module.

ThinkPad X31 2672-C2G 1 GB 3.02 1.08
  • 2 GB with 2 x 1 GB (Kingston KVR400X64SC3A/1G DDR400MHz)
  • It boots with 1 bar.

newer documentation also states 2 GB, even original one did not

ThinkPad X31 2673-C2G 1 GB 3.02 1.08
  • 2 GB with 2 x 1 GB (Team Group INC. TSDR1024M400 DDR400MHz)
  • It boots with 1 bar (1xTSDR1024M400) too.
ThinkPad 240
2609-40U		 320MByte IRETWWW76 n/a
  • Any PC100/256MByte memory in 16 Chip Configuration will do
ThinkPad 570
2644-3AU		 320MByte 1.16 IMET65WW 11/11/99 n/a
  • Kingston KTM-TP390X/256 256MB MODULE FRU 16P6327 - 16 Chips 8 each side
ThinkPad 600
 ?		 288 mb ? ?
  • 416 mb = 256 mb low density PC-100 SODIMM + 128 mb PC-66 SODIMM + 32 mb PC-66 onboard (Note: that which SODIMM you put in which slot matters. This was first reported working on the Thinkpad Mailing List, and it worked error-free for me when I tested it.
ThinkPad 770x
9549		 448MByte 1.11 IIET42WW 09/10/99 n/a
  • 448MB = 256MB PC-100 + 128MB PC-66 + internal 64MB using IBM 256MB MODULE FRU 33L3070 PC 100 CL2 - 16 Chips 8 each side.
  • 512MB = 2x256MB PC-100 + 64MB internal booted up as well. 512MB is due to 440BX-Chipset limitations, 64MB are overlapping or unused.
