Solved!

How increase RAM frequency? (Please help!)

HP Recommended
HP Z220 CMT Workstation
Microsoft Windows 7 (64-bit)

Hi,

 

I recently bought a kit of two new rams: Ballistix 16GB Kit (2 x 8GB) DDR3-1600 UDIMM
but I'm not able to clock them at their full potential (they are working at 800MHZ!!!) via K51 v.01.54 BIOS...

 

Some specs about the HP PC (HP Z220 CMT Workstation😞

 As you can see they are working together with other two old rams (more details below), but they can work at 1600MHz too!!

Some specs about the rams and the clocks they are actually working with (CPU-Z software😞

So actually this is the resultant performance...

..a mixture between the highest values of the 4rams above of course (I mean about CL, tRCD, tRP and tRAS) but they are working at 800MHZ when they can work at 1600MHZ!!

 

I think I have checked almost everything:

So the point now is how to configure it (!!).. unfortunately I'm not able and I need your help!!

 

I already tried:

  • to look for the XMP feature inside the K51 v.01.54 Bios without being able to find it..
    and really I'm not even sure this is the right approach cause the 2 oldest rams don't have it so it could be the wrong path to be followed..
  • I haven't found where to manually set the RAM frequency like in other BIOS versions too!! (as shown in some youtube tutorials etc.)
  • I tried to sacrifice the 4GB of the two oldest rams (disconnecting them) but the PC preformances seems to be the same!! (No XMP feature present inside the Bios too)
  • I also looked at other open questions inside the HP forum like this one, trying to "disable Secure Boot [...] and enabled Legacy Mode" but even for me this is not working..

What do you think?? Is there someone that can help me with this?!?

It has become a really pain in the ass and I really need help from someone, please!!

 

Thank you very much in advance!
Peter

Well, 1067MHz is around half on 2133 MHz. RAM runs dual channel (two channels) therefore each channel is 50% therefore that why 1067 MHz comes from.

Hi Peter,

 

Everything is working properly and the dimms are working at the full potential for the 1600 mhz dimms that you are using.

 

A "k" processor is typically needed to support Intel XMP memory clocks along with BIOS support.  I can't say that the spec's for your PC and the BIOS functionality will allow anything faster than 1600 mhz dimms.

 

I typically don't intermix dimms and stick I with HP's older recommendation to use dimms with the same CAS.

Hi Peter

 

DDR2, DDR3, and DDR4 memory modules double the data rate without having to proportionally ramp up the clock frequency.

 

My PC has DDR 2133 RAM.

 

When I check the frequency of the 2133 RAM using CPUID the DRAM frequency is about 1067 MHz.

 

I am pretty sure your RAM modules are performing as advertised.

Hi banhien.

 

Thanks for your input.

 

It is good to see you, Big_Dave, and I all agree there is nothing wrong with Peter's RAM.

Wait to learn about how DDR4 runs.:smileysurprised:

Hi Adam699,

 

Many OEM PC's don't provide BIOS overclocking options.

 

You are limited to stock memory speeds.

So i need a new motherboard to set my ram speed to 3000 mhz?
