Not sure if in the right place to post this but here goes.

This is a new build.

Gigabyte GA-X58A-UD3R Motherboard
Intel Core i7 930 2.80GHz
Patriot Viper 6GB (3x2GB)

Have just powered up on the default bios settings, the cpu is posting between
1616.0 x12 and 2833.0 x21

Keeps changing but stays at the lower of 1616.

Anyone know WHY>???

CPU Properties:
CPU Type QuadCore Intel Core i7
CPU Alias Bloomfield
CPU Stepping D0
Engineering Sample No
CPUID CPU Name Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz
CPUID Revision 000106A5h

CPU Speed:
CPU Clock 1616.9 MHz (original: 2800 MHz)
CPU Multiplier 12x
CPU FSB 134.7 MHz (original: 133 MHz)
QPI Clock 2425.4 MHz
Memory Bus 539.0 MHz
DRAM:FSB Ratio 4:1
 
Hi there, welcome to the OCUK

The title says "not posting", but your post says it is. Which is it? Or is it that it doesn't say 2.8GHz when it does post?

I suspect that your "problem" is intel speedstep. This is a power saving feature that reduces the multiplier (and thus the CPU frequency) when the CPU is not heavily loaded.

I suggest running a stress testing program like OCCT and see if the multiplier jumps up under load. If it does, all is well.

Also, you might want to manually raise your memory multiplier, it is currently set to motherboard default speed (1078MHz). I suspect it is rated to go a bit faster.

Sorry yes it does post but as i said it changes.. running a stress test with everest does make it stay at 2833 x21. So all is well you think. and thanks for the quick reply.
As for the memory how would i do that.lol sorry new to this...
but many thanks

Just run occt v3.1.0 and it says cpu frequency 2819,0 and then original 2800.0 overclocked 1%
memory 134.9 current and org 133.0 1.5 % overclocked.

Strange.

Its speedstep, a powersaving feature. The CPU only runs at full speed when needed. (as above sorry its early)

And this is the most common question raised one here !!

There is nothing to worry about, the only time its worth turning this off is if you are going for high overclocks as it can effect stability then, otherwise keep it on.
 
Ah, that sounds fine - everything working as it should.

As for the memory, you will need to go into the BIOS and change the memory speed, timing and voltage. However, this should be easy with your board and RAM as you can simply enable the "Extreme Memory Profile (XMP)" on the memory page of your BIOS, this will put in the correct settings. Have a look at your motherboard manual for the full details.
