Dell T410 Memory Running Too Slow

Question

I installed in my Dell T410 (2) sticks of Crucial 8GB DDR3 PC3-10600 • CL=9 • Dual Ranked • x8 based • Registered • ECC • DDR3-1333 • 1.35V • 1024Meg x 72. Memory is in socket 1 and 2. No other memory is installed. Upon boot, memory says it is running at 800MHz. Installed CPU-Z to verify. It says it is running at 400MHz which doubled is my 800MHz. From everthing I read, the memory should be at at 1067 MHz.

Went into BIOS and did not see any setting that could be changed. I did notice that it is running at 1.5volts instead of 1.35V.

I reinstalled the (4) 2GB sticks that were in before with same specs as above except it wasn't registered. It ran at the same speed (800MHz).

Shouldn't this memory be running at a faster speed?

Thanks,

Steve Reynolds

Hi Steve

Thanks for the info.

From your picture, you are using Intel E5503 which supports only 800MHz memory speed. You can refer to Intel page for more info:- http://ark.intel.com/products/37094/Intel-Xeon-Processor-E5503-4M-Cache-2_00-GHz-4_80-GTs-Intel-QPI

Here's a technical guide for T410, refer to page 32 on the supported processor descriptions and features:- http://www.dell.com/downloads/global/products/pedge/en/server-poweredge-t410-technical-guide-book.pdf

Hope this helps.

Hi Steve

In order to achieve 1333MHz, for dual ranked dimm, all you will need to follow is:- For single or dual-rank memory modules: One memory module per channel supports up to 1333 MHz. Two memory modules per channel supports up to 1333 MHz.

I assumed that your server only has 1 CPU? So basically, you will need populate the 2x dimms in A1 and A2, which is your current state.

Besides that, CPU also play a role to affect the memory speed. So I would suspect your CPU does not support the higher speed? Could you let us know what CPU model you are using please?

Also you might want to update the server BIOS to the latest:- http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/poweredge-t410?driverId=99KV2&osCode=WS8R2&fileId=3285775867&languageCode=en&categoryId=BI

Let us know how it goes.

Correct, I only have 1 CPU.  I have attached a screenshot showing the CPU info. Steve

Attached is Bios info.  I looked at the later Bios descriptions but they didn't mention support for faster memory.  Steve

Manfred, Thanks for the info.  Glad to know that everything is working as it should.  I didn't think about the processor's ability being less than the motherboard's. Steve
