T3500 memory error - not optimal configuration
Hello,
My T3500 is out of warranty. Now the system board (K095G) failed.
Called Dell Spares no system boards in stock. Found an online supplier that had T3500 System Boards (XPDFK).
purchased one and replaced system board. On startup the firmware detected a memory error for DIMM slot 1. Message was Memory error not optimal configuration. Checked memory configuration matrix had 2ea. 2GB memory sticks in slots 1 and 3. Replaced memory with 3ea. 4GB modules in slots 1, 3, 6. I was thinking this error was a channel mode issue, since the error repeats with either 2 module or 3 modules, this must not be the issue.
Same error with new modules. System boots to O/S after pressing F1. It runs well. Ran full memory diagnostic test and both sets of ram modules passed with out error.
Does any one know how many different system boards were used in the T3500?
Or if there is a solution to this issue?

Read page 41 here for allowed RAM configurations. Be sure to check slot numbering printed on the motherboard because they may not be physically in logical numerical order. :emotion-5:
After you get the modules in the right slots in an allowed configuration, clear BIOS by powering off, unplugging and removing the motherboard battery. Then press/hold power button for ~30 sec before reinstalling the battery.
I suppose it could be an issue with the replacement motherboard, so maybe you should contact the seller.
EDIT: The links are messed up in this new forum upgrade, so look here: ftp://ftp.dell.com/Manuals/all-products/esuprt_desktop/esuprt_dell_precision_workstation/precision-t3500_Service%20Manual_en-us.pdf

Hi. I owned the T3500 and currently own the T5500.
Yes it does support the i7 920. Get the Intel Xeon W3520 instead. It's virtually the same processor at a 1/4 of the price of the i7 920. You can find them for $15 or less on ebay. Make sure you have the U016F heatsink for any quad core processor you may install on this thing. The T021F heatsink is a joke and it can overheat your PC. Throw it away
While you're at it. Ditch the T3500 altogether and get yourself a thinkstation s20, or hp z400 (same chipset as the T3500). These dell machines, specifically the (T3500/T5500/T7500) line, are awful. The design is terrible in all 3 models. It impacts performance a great deal. I had been a loyal Dell user until I bought these machines. I hope you have better luck.
