[SOLVED] ram 667 to 1333 Mhz

[Gswiss]

On my Medion notebook I've got 2 Kingston 667 Mhz DDR3 rams (4GB each). Can I replace both with 8 GB 1333 Mhz rams with the same voltage (1.5V)? I'm running Windows 7 SP1 Ultimate X64, so the ram size is taken care of.

This is depending on the Medion model you have. Which one is it exactly?

If you are looking at DDR3-1333 modules, those would also be running at 667Mhz, as RAM modules are named according to their transfer rate, which is double the clock rate. It sound like you have DDR3-1333 already.

Load up CPU-Z and give us the exact 'part number' listed under the SPD tab.

Running 2 different memory modules is never recommended. You may be running in single channel mode with very loose (slow) timings.

Please post the memory tab of CPU-Z.

Is one of these sticks soldered onto the motherboard?

The Tab descriptions are in message #6 above

The notebook has been running like this for years without a hitch. It's 2 identical sticks from different manufacturers.

I'm considering two Kingston ddr3-rams (PC3-10600) 1333 Mhz 8 GB each. Does this mean I could go ahead and use them?
