CML16GX3M2A1600C10 not making 1600Mhz

[Homdax]

I recently noticed that my RAM - which should be correct for the computer - is running at 1333Mhz instead of 1600Mhz on an olde HP Desktop, the EliteDesk 800 G1 SFF.

 

The speed has been checked both in BIOS, reports 1333, and in Windows, also reports 1333 - on 1600 modules. This is the RAM in question: https://www.corsair.com/us/en/Categories/Products/Memory/High-Performance-Memory/Vengeance%C2%AE-Low-Profile-%E2%80%94-16GB-Dual-Channel-DDR3-Memory-Kit/p/CML16GX3M2A1600C10

 

HP's recommendation is

• industry-standard 240-pin
  
• unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
  
• 1.35 volt or 1.5 volt DDR3/DDR3L-SDRAM DIMMs
  
• support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
  
• contain the mandatory JEDEC SPD information
  
• 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
  
• single-sided and double-sided DIMMs
  
• DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
  

 

Something might be wrong and the Corsair Memory Finder don't seem to have this system. Any advice?

 

BTW this is obviously not the PC that is listed in my Specs.

Have you tried configuring your bios to 1600mhz for the memory? I've only recently got back into PC builds after a 20 year break but both the units I built recently with very up to date mobos required some input in bios from me to get the ram running at my desired speed.

The HP bios do not have any options to set speeds, that is why I mentione power management, since it does affect cpu speed and may also affect overall performance by reducing clocks when computer on stand by. Other than that there is no other options, bios is pretty basic

 

The only thing I can figure out is the ram compatibility, it should be a PC3-12800, the sticks are PC3-12800 so the only remaining options are if timings or anything else is not matched, causing this problem.

No one with an additional reply to this?
