Rams

[Akamii]

my current ram is single 4GB 1333Mhz 9-9-9-24 1T

but in cpu-z the ram frequency is 655.1Mhz

and the NB Frequency is 798.1Mhz

what does that mean? i think the ram should run at 1333mhz so what is this?

also does the ram speed affect the gaming fps? for example from 1333mhz to 1600 by how much could be the effect?

please guys just explain to me whats going on? whats the real speed of this 4gb ram ??

 

also i never heard of 9-9-9-24 .. just 10-10-10-26 and 7-7-7-20  @ 1333Mhz so what is that?

 

here's some pics from cpu-z

I'm confused as well. All I know is whatever is in the BIOS is most likely true.

With RAM frequency, you need to know that DDR stands for Double Data Rate. That frequency you see in CPU-Z, double it.

665.1 x 2 = 1330.2. Pretty close to 1333Mhz.

RAM frequency makes little difference in games, maybe a little bit at most. Some games, however, like Battlefield do enjoy a higher RAM clock.

 

And the 9-9-9-24 are just the timings. Don't worry too much about those. They make little difference with DDR3 memory

Nothing looks unusual, really.

so by how much jumping from 1333mhz to 1600mhz would give more fps?

[miagisan]

dual channel you take the speed multiplied by 2

real world (gaming, and every day uses)...no difference in performance.

im using single ram

[miagisan]

im using single ram

oops missed that....go to your bios and see if it is just clocking it slower, manually change the speed. and 9 cas is pretty common

1330.X .. cant remember .what

1333MHz 9-9-9-24 is one of the JEDEC industry standards for DDR3 RAM.

 

You can look all this up on the official JEDEC website, but you need to registry and become a member. Otherwise, there are sources on the interwebs (Wikipedia for an overview).

Standard Name

DDR3-1333F * -- I/O Bus Clock: 666.66 MHz, Data Rate: 1333.33MHz, Timings: 7-7-7, CAS latency: 10.5 nanoseconds

DDR3-1333G -- I/O Bus Clock: 666.66 MHz, Data Rate: 1333.33MHz,Timings: 8-8-8, CAS latency: 12 nanoseconds

DDR3-1333H -- I/O Bus Clock: 666.66 MHz, Data Rate: 1333.33MHz,Timings: 9-9-9, CAS latency: 13.5 nanoseconds

DDR3-1333J * -- I/O Bus Clock: 666.66 MHz, Data Rate: 1333.33MHz,Timings: 10-10-10, CAS latency: 15 nanoseconds

..

* = Optional

 

AS you can even see in your second screenshot, 9-9-9-24 is ONE of the JEDEC memory timings programmed into your DRAM modules.

 

 

Already mentioned, DDR3 RAM is frequency is essentially multiplied by two. For DDR3-1333 MHz, the actual speed is ~667 MHz, while the effective speed is 1333 MHz. Similar in Video Memory (VRAM) found on graphics cards, GDDR5 (most common these days), the effective speed is 4x.

 

For an example, on a GTX 980, the Memory Clock is advertised as 7.0Gbps (7000 MHz). This is the EFFECTIVE rate. The memory chips are actually operating at 1750 MHz.

 

 

For most systems and gaming applications, increase in DRAM frequency has very minor effects in performance. In many cases, the performance increase from 1333MHz to 1600 MHz / 1866 MHz may only be 1~3 FPS. Whether or not the cost to purchase a whole new RAM kit is worth the minor increase is up to you. To be honest, you can easily gain that 1~3 FPS (or more) by mildly overclocking your Processor or Graphics Card.

 

Here is a review done by the people over a 'Legit Reviews' earlier this year. They compared DDR3-1600 MHz versus DDR3-1866 MHz on a Intel NUC.

Civilization: Beyond Earth @ 1080p on Minimum Image Quality settings

1600 MHz: 36.66 FPS (average)

well so at the end my rams are good since i dont play games that exceeds 4gb of ram right? .. and upgrading to 1600/ 1866 doesnt worth the cost 

and btw i didn't understand the JEDEC industry standards for DDR3 RAM part .. what does that mean ? that means a good ram or wut, sorry im not a huge pro , also just checked my bios and the ram runs @ 1330.5

[LogicalDrm]

so by how much jumping from 1333mhz to 1600mhz would give more fps?

 

About 1-3 depending on game. Huge jump like 1600 to 2133 made 7 fps difference in BF3. So really nothing.

 

dual channel you take the speed multiplied by 2

 

No. Dual channel has nothing to do with speeds. Even single sticks are DDR. Speed is multiplied per stick. So having triple or quad channel doesn't mean that your speed will be x3 or x4.

yeah .... my brain was not functioning as it should. Damn 20 hour shift at work /shakes fist

so should i upgrade my 1333mhz ram to higher frequency? or it doesnt even worth it?

[Faceman]

so should i upgrade my 1333mhz ram to higher frequency? or it doesnt even worth it?

No, its not.  What you should do is buy a 2nd 4GB stick of 1333Mhz, 9-9-9-24 RAM.

[LogicalDrm]

so should i upgrade my 1333mhz ram to higher frequency? or it doesnt even worth it?

Its not. There are few games that would advantage from speed. But there's more which gain from capacity. So if you are thinking of buying more ram anyway, do as @Faceman said.

[Akamii]

thank you dude

There are some guidelines DRAM manufacturers have to follow. There are rules for everything -- even for computers.

This means there is nothing for you to worry about; your DRAM is running as intended.
