Ram questions for T3500

I have a T3500 I have started started sourcing items to begin an upgrade, but I'm kind of stuck at RAM. Are there any in depth explanations of RAM configurations for the T3500? I had two of them given to me to tinker with, each with 4GB ram. I managed to Frankenstein my way up to 6GB using slabs from the second machine. I have noted the slots have alternating black & white retention clips. I populated the banks with a mix of the stock slabs that came with the machines: Samsung 1Gbs with alternating part no.s 10600 in one, 8500 next, 10600 next, 8500 next, and so on up to the full 6 banks.

Q1. Is there a good primer/explanation on what I'm looking for to max my ram up to 48G? (I'll be happy with 24 actually)...specifics on what slabs go into what banks in what order (and why), seeing as how it is pretty picky about what order they are seated in?

Q2. My X5680 has arrived. As I'm still running only 6G of stock Ram and stock PSU is there any point to seating the new CPU & heatsink to test it? Or am I stuck until I get my RAM upgrades? (Ie. is the processor "Too much Processor" for the stock ram I have in there now?)

  • While it's been a while since I had a T3500, I can't remember how to upgrade it to 48gb, but here is the link for the machine's stock memory configurations from Dell.


  • HI...  I'm a former Intel Silicon Apps Eng...  always an Audio/Video producer.

    11 years ago, I chose the T3500 (New from Dell) to use as my ProTools HD Native workstation.

    Years go by, OS no longer supported, Upgrade, upgrade ,.oh and ...UPGRADE!!

    So, After looking deep into the T3500 MB architecture and CPU socket, I initially wanted to improve performance for ProTools HD Native, and more processor intensive WAVES plugins.

    So I replaced my stock QUAD core XEON processor with:

    Intel Xeon SLBV7 X5670 2.93GHz 6.4GT/s 12MB L3 Cache Socket LGA1366 HEX Core... for 12 logical cores/threads.

    With the ICH10 Chipset, I had to update the BIOS to server version Rev A17. Intel Rapid Storage HAL,  V 10.0.19041.1151.

    Then installed 48GB of RAM... CORSAIR Vengeance Pro Series DDR3, QUAD Channel, 1600MHZ  RAM.  Added USB 3.1 and 3.2 and USB-C Expansion (keeping USB license keys and some USB MIDI stuff on the 2.0 ports). Added 24 TB of external USB storage and changed ALL internal drives to 1 & 2 TB SSDs including another 1TB M.2 on the bus. Also added Bluetooth and 5G wireless LAN on the PCI slot with a StarTech PCI to PCIe X1 Riser... and wired GbE.

    Boot time with this configuration is <15 sec into Windows 10 Pro. Depending on projects... I can change out the boot drive (in 4 min) and return to my original Win 7 Pro 64 drive... and now it's a Win 7 machine. (Due to Waves Plug-in rip offs.. long story) STLL the original Power Supply!

    I call this machine "FrankinPuter" ...as it sits now with ORIGINAL MB... it's a BeAsT!

    Not that this is practical... but I can almost edit 4K (4096 x 2160).  The bottleneck now for video production is the GTX 1050 ti (at the time...1080HD GREAT! 24-bit 48KHz audio production and mastering... Great). Now, Video frame rates are choking at 1080P when video comps get 1 layer deep. So... AGAIN, I need to upgrade GPU. Going with RTX 2080 or RTX3060. But I need more JUICE!!

    FINALLY... to the POINT!! (haha)  I'm looking to upgrade stock PS to 750W with additional GPU power.  I saw that Jay did a PS upgrade on YouTube... BUT,

    The power supply he used (EVGA 700B), which is now discontinued. I was wondering if anyone has qualified the newer EVGA 750BQ, 

    110-BQ-0750-V1 Bronze.

    ANY help would be appreciated. I really only want to do this once. This beast still has lots of life left!



  • Still looking for a suitable PSU myself. I am in the "I only want to take this beast apart once" boat. Also considering front fan replacements since I'd also like to not have to listen to a jet engine all the time.

    • Steph Chabot Steph Chabot I have a T3500 with 48Gig of memory.  24 Gig I use with Primocache on a 960 EVO Sata drive.  I have not been able to find a way to boot off my NVME drive.  I hear of people using CLOVER to boot the NVME drive but have yet to be successful.    If you find a way to boot the NVME drive please let me know.    All the Best, Mick

      Haven't tried this in a while... but the only two thing I can think of off hand...

      1. Make sure that you make the NVMe drive bootable (Boot Partition). You can use a partition program to add after the fact if you have data on it.

      2. You should see the drive in the BIOS setup if bootable. Even tho its an NVMe it still should be treated as a SATA drive (assign an appropriate drive letter). If you have a decent bus PCIe card. StarCom makes a bunch of good ones.

      Good Luck! 

  • I bought the EVGA 110-BQ-0750-V1 Bronze.... I can now say that I've qualified this Power Supply. Easy drop-in... Lots of options, cables and quiet.

    Unfortunately, the MB has to come out to cut the cable ties underneath. Wasn't a big deal... just a little extra time.
