Solved Ram not clocking at advertised speed?

[Pyro]

I have corsair vengeance ram advertised at 3200mhz, but I just checked and it's running at 2133?

Thanks

it may be as simple as this;

“Like the ticking of a clock, each tick represents a single hertz or cycle (the opening and closing of a transistor gate in this case).
A speed of 1Hz, for example, is one cycle per second; 2Hz is two per second; a MHz is 1,000,000 cycles per second; you get the picture.
The problem is when DDR (or double data rate) RAM came on the scene, it changed how data transfers were registered. Instead of only actuating once on the rise of each clock cycle, it could now also process an additional operation on the fall of that same clock cycle, effectively doubling the rate at which the DIMM could process data.
The figure for accurate measurement of data transfer requests then shifted from MHz to MT/s to adjust for this change, despite the fact that memory still operated at the same frequency.
However, marketing apparently didn’t get that memo, because many companies, in a bid to tout it as the next big thing, ignored the MT/s figure, instead referring it as MHz, while modern day memory quoted at 2,400MHz, for instance, only operates at half that frequency.”

or maybe your mobo only handles up to 2133?
what are your PC specs?
is this new memory?

Brand new PC, all the parts are brand new and were handled under the overwatch of a professional (I know someone who works with computers for a living). And the board supports up to 4000-something mHz

3200MHz is the tested speed which is what it achieved when overclocked, 2133MHz is the serial presence detect speed which is what the BIOS will detect when you boot up, laymans terms, the RAM needs to be overclocked to be able to achieve 3200MHz.

In case you are not already aware, the i7-8700K that you have only supports DDR4-2666MHz RAM when running stock settings.

I did not know that, oh well. 2133 is still decent right?

Thank you

2133MHz is not only good it is stable, start OCing and things can go wrong.

Anything else that we can help you with or should we mark your thread as solved.

You are welcome

That's good, no system errors!

I'm still having some gaming errors despite the PC change(I have a few earlier posts about this issue, on an older computer), I thought this could be causing it but I guess not. But that's not for this category I think.

Again, thank you very much.

You are welcome and thank you for concluding your topic

Cannot discuss troubleshooting in this thread as it is going off topic but fwiw, two separate computers and the latest one is a high end build so for me the common denominator is your internet connection which was mentioned in your previous thread.

NB: There is no PSU on your PCPartpicker list but as long as the one that you have is not a cheap, poor quality, under powered unit it is not likely to be the cause.
