Corsair Vengeance 1600MHz running at 1333MHz

IdiotCoder · 5 Jun 2011 at 20:57

Hey guys,

So, as the title says I have 8GB (2x4GB) of Corsair Vengeance 1600MHz with MSI P67A-G45 and Intel i5-2500k.

In MSI's Control Center the RAM was reporting running at 1333 (667) MHZ, and it's voltage was ~1.65V.

I went into the BIOS, changed the speed to 1600 and the voltage to 1.507V.

Now in Control Center it shows correct voltage but the speed is still being shown as 1333MHz.

Any help would be great!

Thanks in advance!

Download CPU-Z and click on the memory tab (not the SPD tab) just to be sure.

It should read 800MHz (doubles to 1600MHz for DDR).

CPU-Z

Thanks Surveyor! Just as you replied I had CPU-Z open and seen that it does in fact say 800MHz (798.2 to be precise).

I take it this means everything is fine?

Yes.

It looks like the MSI Control Centre is reporting the speed incorrectly.

If you're bothered with it being 798.2MHz turn off Spread Spectrum in the BIOS and it should go to 800MHz.

Thanks a lot man!

No problem.

Does that mean you've tried it?

Yup, worked a charm!

Any idea why MSI Control Center is reporting the RAM to be running at 667MHz?

Perhaps it doesn't actually read the speed the RAM is actually running at but the SPD data.

If you look at the SPD tab in CPU-Z 1333MHz might be the highest value given as 1600MHz is "overclocking".

Cheers,

Yeh, under Max bandwidth it has 667MHz.

Just glad it's actually running at 1600

You're welcome.

At least you know it's running properly now.
