Windows 7: 1600Mhz RAM only showing 1400Mhz?

A) why would it deliberately underlclock

b) why isnt the overlcock going past 1400Mhz when the board supports 1600Mhz

C) i never had to change the timings to get my dad 1333Mhz RAM to run at 1600Mhz (mind i used XMP on those)

D) i have not touched the FSB setting? - just the RAM speed overclocking

WOW I just told you it will always default to 1333mhz when it is installed

You hit a overclock feature that will focus on Bus speed not Core Clocks which will bring the ram up only a few Mhz and potentially add more juice on the ram then is needed you didn't have to touch FSB the program did it for you

XPM may work but only if ram is correctly adjusted like i said before it has to be adjusted time cycles voltages and all if you don't know how to i suggest you read a little on it

what your missing the point is that the motherboard is 1600Mhz supported and the OC feature is locked to a MAX of 1400Mhz - so theres something wrong there...

I dont think the RAM supports XMP - I just tried it

Ive done this many times and something isnt right... you simply change the speed of the RAM to 1600Mhz... but it maxes at 1400Mhz

1600Mhz RAM
1600Mhz MOBO

regardless of 1333Mhz underclock its not letting me get to 1600Mhz...1400Mhz only

the setting your talking about is the System Clock Multiplier (no longer called FSB) which ALL bus speeds are derived from and is 100Mhz by default 16x100Mhz = 1600Mhz... you dont change that too over clock the RAM from 1333Mhz to 1600Mhz - it has its own overclock options as shown in the video posted...but his wont go past 1400Mhz...why? ive never encountered this problem before and done this many times (overclocking RAM - and yes 1333Mhz to 1600Mhz will OC quite fine on 1.5V as thats what its rated for)

so why is it locked at 1400Mhz when the board says it supports 1600Mhz... your answer was to overclock it...my answer is ive tried but wont go past 1400Mhz - it should go to 1600Mhz

1333mhz is Not an underclock, its the default speed of ALL ram regradless of its speed (even 2100mhz) because it allows for compatibility with all motherboards and chipsets.

if your ram is rated at 1600mhz then you need to consult your motherboards manual to get the correct timing for your ram.
Again this is NOT overclocking, its simply telling your motherboard how to handle the ram.

if your only getting 1400mhz then you have the timings incorrect. and as I stated some ram requires a change of voltage.

regardless of you never having to go through this, this is the process of installing ram! again its not overclocking and your motherboard is not underclocking!

You are confusing my statements with yours you are the one who said you tried to use a overclock feature and it stuck at 1400mhz

I told you the timings need to be adjusted and the cycles there is no where i said to overclock your ram

Overclocking your ram would mean going over 1600mhz not to 1600mhz it's already rated speed

you can swap that ram out a 100 times over and the result will be the same until you study your Mobo and Bios better that is the only way

Solar and Badger are correct, the RAM has installed at default timings and shouldn't need to be overclocked to 1600MHz, it's just the timings that need adjusting. If they don't use XMP profiles they'll need to be set manually, not overclocked as they're not underlocked.

I cant see how changing the timings would allow for an overclock to 1600Mhz...??? i cant fathom it

any other time ive just changed the mulitplier from 13x to 16x and that was that.... fine tuning timings is to increase the card speed in different ways and (as far as Im aware) is unrelated to changing the multiplier??

if this was the case them why doesnt Gigabyte say 1600Mhz (OC - if you change the timings) doesnt make sense, they said the board is capable of 1600Mhz and the RAM is 1600Mhz so it should allow the RAM multiplier to go to 16x if Gigabyte say 1600Mhz supported...



you stick in 1600Mhz RAM and it only allows to overclock to 1400Mhz..... with the RAM multiplier....thats not right?

also - actually just checked my system as it actually does have 1333Mhz ram in and was OC'd to 1600Mhz by the RAM multiplier...no messing with timings or nothing

snadge its not overclocking!!

over clocking is increasing the clock speed higher than that of which it was sold to you.

so if you bought 1600mhz ram an overclock would be to increase it to say 1866mhz or 2133mhz ect.

if you go out and buy 1600mhz ram and put it in any compatible motherboard by default it will ALWAYS run at 1333mhz!

setting the timings to your correct ram is not overclocking. its just adjusting the bios to the correct settings to run the ram.

think of it as putting a bigger engine in a car and keeping the same ecu, you would need to tune the ecu to account for the new fuel flow ect..

to overclock ram is a completely different process.

motherboards support a wide range of ram timings from low latency to high latency, but these settings are not changed by the bios by default. it only sees every stick of ram as the same, so hence the reason it runs at 1333mhz not its native 1600mhz.

you have to tell the bios you have lower latancy ram by adjusting the timing.

if you have ram that is rated to 1333mhz and want it to run at 1600mhz yes that is overclocking and nothing to do with the timing.

however just because your motherboard says it supports 1600mhz and you want your non native 1600mhz ram to run at this speed doesnt mean it will.

What I suspect is happening is that the RAM you bought doesn't have a XMP profile

Most RAM that's rated for over 1333MHz will have an XMP that automatically tells the MOBO how to adjust the timings, voltages, etc to run at the rated speed, so you would have never needed to do anything manually other than enable the XMP.

The RAM you bought however must not have an XMP, so everything must be done manually; i.e. you need to go into the settings and change the TIMINGS and possibly VOLTAGES (not the multiplier) to those that the RAM supports, which can be found on the manufacturer's website and most online merchants such as Newegg or Amazon (though you should go to the manufacturer's page first)

So you won't be overclocking your RAM to 1600, you're simply letting the motherboard run it at the higher speeds it supports

Just a note guys, Ivy Bridge supports a default RAM of 1600 with no adjustments. Sandy and prior only 1333.

The H series chipsets are limited in what overclocking settings can be made and you have a locked CPU.

To run RAM at faster frequencies usually requires "looser" timings to get it there.
