which memory for my T7500
Hi,
I have several single CPU(quad core) T7500 workstations with 4x2GB memory in each. Total slots are six, making two available. I want to make maximum use of the last two slots..
The currently installed DIMM size is 2048MB 1333MHz Registered (Buffered) DDR3 DIMM, Hynix Semiconductor (Hyundai Electronics) HMT325R7CFR8A-H9
While chatting with Dell rep, they directed me to this link which is definitely compatible. They mentioned, 1x8GB 1x16GB or even 1x32GB is not available.
I am wondering if following work in pair in my T7500
<- 32GB
<ADMIN NOTE: Broken link has been removed from this post by Dell><- 16GB
<ADMIN NOTE: Broken link has been removed from this post by Dell> <--8GB
I see this one from a third party site but not sure if it will work.
http://www.serversupply.com/MEMORY/PC3-10600/16GB/KINGSTON/KTD-PE313LV%2F16G.htm
NOTE: Please copy-paste the links above, if these don't work as they are.
Can you please help?
EDIT:
This is the best I have found yet http://tinyurl.com/b6wcdf2 <--16GB.
If the above 16GB works? then, 4x2GB + 2x16GB = 40GB memory in one T7500. 40GB itself is odd but hope that's fine.

No one?
I know T7500's memory configuration questions have been asked many times in this forum. But everyone has different configuration, especially CPU models. Mine is Quad Core Intel Xeon Processor X5687, 3.60GHz.
As I understand from the supported configuration which I also understand is old, I think, I can put two 16GB dual rank DIMMS in addition to existing 4x2GB(single rank). The new 2x16GBs I plan to put those into slot 1 and slot 2 which are farther from CPU. Rest of the 4x2GB can go into remaining slots.
I plan to put these 16GBs into the workstations.

If the 4x2GBs in the 3,4,5,6 is not accepted by T7500, I will just keep those aside and run T7500 from 2x16GB in slot 1,2
On the other hand, I wonder if Dell discontinued precision T7500 w/s and for what reasons..

Hi I'm in the same situation I'm planning on purchasing a 16GB x 3 kit, Part I'm going to use is KVR13LR9D4K3/48
Do 16 GB dual rank RDIMMS work ?
Thank you

Hi-
Yeah the dual rank 16GBs should work in T7500. At the time when dell created those documents for T7500, only quad rank 16GB compatibles may have been present in the market , that's why probably only quad rank 16GB got mentioned. I have seen forums discussions where people had good luck with dual rank 16GBs.
In fact using only dual rank dimms in this system(triple channel, all channel populated) gives better performance than using only single rank , quad rank , or dual rank+single/quad combination And quad rank may also run at 1066MHz instead of 1333MHz which is another issue when combined with other ranks.
I am waiting for budget to order many 3x16GB 2R kits from crucial.
Good luck, let me know how kingston dimm works.

Good news ! the 16 GB Dual rank RDIMMS work.
I purchased the Kingston Kit KVR13LR9D4K3/48 kit. Each of the 3 RDIMMs are dual rank
here are the kit details www.kingston.com/.../KVR13LR9D4K3_48.pdf
This kit was around $400.00 allot cheaper than so other kits I found that were offically supported with this system.
My motherboard is the OD881F version A07, I was also able to reuse the exiting 3 x 2 GB Dual rank HYNIX RDIMMs that were in my sytem. My total system memory is 54 GB of ram.
Slot 1: 16 GB
Slot 4: 2 GB
Slot 2: 16 GB
Slot 5: 2 GB
Slot 3: 16 GB
Slot 6: 2 GB
Memory as reported by HWiNFO64 v4.12 is running at Clock speed of 665.0 (5:1) ration in Triple channel mode. Timings are 9.0-9-9-24
I very happy this worked out. Upengan78 was correct.
Naim.

That;s really good to know Naim. Definitely a proof of concept. This thread should all those who have similar concerns.
Even better is that you are able to use existing hynix dimms too. Hope you are not seeing any other strange issues such as random reboots or crashes...
Couple of questions,
1. Are you running windows by any chance. I am not sure whether can use 54GB on windows(x64), so I guess you are using Linux. Or May be you are using windows server OSs ;)
2. What version is your BIOS.
3. Could you also post o/p of dmidecode --type 17 ? (assuming you are running linux.)
4. Just out of curisity, are the kingston dimms using hynix chips on them?
Our order of memory at Cr**al needs extra verification using utili*y bill which is really odd, so I might go ahead buy kingston dimms canceling cru*al order.
Enjoy..

Hello again,
Here are the answers ...
A1 System is stable, I'm running Windows 2012 as an OS, the OS reports 54 GB of RAM and it's all usable.
I've used up 47 GB of ram by creating a RAMdisk and I've done a full R/W of the disk no issues. i'm running VM's from vhd files on the ram disk.
A2. I flashed to the latest bios A15 release date 2/27/2013 prior to installing the new ram.
A4. The chips on Kingston 16 GB Dimms are ELPIDA J4204EBBG-DJ-F 123506E761
A3. dimdecode for windows type -17
