Hello,

I have a Kingston Hyper X 8GB (2x4GB) and it's only showing 669.76MHz in CPU-Z. Is this normal or i'm missing something here?

system is NOT overclocked...

General

Type: DDR3
Size: 8192 MB
channels #s: Dual
DC mode: Unganged
NB Frequency: 2009.0 MHz

Timings

DRAM frequency: 669.7 MHz
FSB:D RAM - 3:10
CL: 9
tRCD: 9
tRP: 9
tRAS: 24
tRC: 33
CR: 1T

SPD

slot 1: DDR3

max bandwidth: PC3-10700 (667 MHz)
manufacturer: Kingston
Part #: KHX1600c9d3/4GX
serial #: 4d1ad943


slot 3: DDR3

max bandwidth: PC3-10700 (667 MHz)
manufacturer: Kingston
Part #: KHX1600c9d3/4GX

DDR = Double data rate. Your memory is running at DDR 3 1333 speed.

CPU-Z always shows it like that. My DDR 3 1600 shows as 800Mhz.

The actual IO bus frequency for DDR3 is 4x the DRAM chip clock speed. The DDR3 interface makes 2 data transfers per IO bus clock cycle for a total of 8 IO transfers per DRAM chip clock. With an IO bus speed of 667Mhz this gives a transfer frequency of 1333Mhz (often abbreviated as 1333MT/s to clearly distinguish between transfer frequency and oscillator frequency) and a chip frequency of 166Mhz. The chip frequency is almost never advertised anywhere but is an important part in determining memory latency. The reason for this is that while the memory IO bus frequency has increased dramatically over the years, core memory speeds have not. DDR SDRAM has an IO bus: memory clock ratio of 1:1 which resulted in two IO transfers per memory clock. DDR2 has an IO bus : memory clock ratio of 2:1 which results in 4 IO transfers per memory clock. Similarly, DDR3 has an IO bus : memory clock ratio of 4:1, which results in 8 IO transfers per memory clock.

Knowing this, DDR-200, DDR2-400, and DDR3-800 all have memory modules running at 100Mhz. DDR-400, DDR2-800, and DDR3-1600 all have memory modules running at 200Mhz.

Hope this helps

@anort3...thanks for that quick response. so you mean my memory is as good as 1333MHz only? i thought we're basing it on the part #? i am not sure how to check it aside from the packaging. is this normal sir?

Based on the part number it's DDR3 1600 right? If so you will have to manually set the speed in BIOS. The timings look correct at least if it's supposed to be DDR3 1600 cas 9.

If you had DDR3 1333 and bought this expecting it to be faster you pretty much wasted your money. You will never see a real world difference unless you use memory intensive apps all day long.

@anort3...jeezz..you guys are awesome...actually i checked my BIOS prior to this and under DRAM i have "AUTO" in my BIOS but when i selected it, i have options to change it a notch higher..i think max is 1600...so does this mean that my mobo will just adjust to the needed speed in case my apps need it? is everything normal based on the data that i posted?

thank you very much guys!!

ooopsss..one more thing, i'm looking for a cooler which is convenient to install w/o dismantling my system, i mean just replace the stock cooler and screw it, no need to put a back plate like the hyper 212 evo (this is what i'm considering but hard to install) do i have to create a new thread for this? i guess i've created one however, no one bothers to answer my question :(  :sweat:  :cry:

Your memory module is capable of running at a variety of specified speeds but is usually only marketed at the highest one. Most performance RAM (which certainly includes the HyperX lineup) are marketed above the standard specifications supported by most CPUs. The out of specification speed profiles are marked as such on the memory modules themselves and thus your system won't try to run the memory at those speeds unless explicitly told to do so. In this case, your memory module has a "standard" profile for DDR3-1333 which is what it's running at right now. Most new memory also contained performance profiles so that the memory can be configured at its marketed speed with little effort but this feature needs to be enabled manually. How this profile is enabled varies by motherboard manufacturer but is usually labeled under the Intel trademarked specification "XMP" which stands for "Extended Memory Profiles". It can often be found under the overclocking section of your system setup. Enable XMP and select an XMP profile (there may be more than one, but the marketed speed will be the highest profile number) and this will configure your memory controller to run the RAM at speeds higher than those officially supported by Intel. 95% of the time this works without issue but since its not officially supported and is technically overclocking (unless run on a CPU which supports DRDR3-1600 natively) you may encounter issues.

So yes, your result is normal given that you haven't enabled the high performance speeds yet. If you do so that 667 should jump to 800.

@Pinhedd..jeeeezzz...you 2 are really awesome :wahoo:  :bounce:  but changing it in my BIOS manually at 1600MHz will mean that I'm overclocking my system right? how about the timings? it will go hand in hand with others when i'll change it to 1600MHz? I am running athlon x3 455 so i'm not sure if this runs 1600MHz. don't know how to check it though :cry:

Since he has Unganged and a NB frequency listed he has an AMD system and XMP does not apply.

OP see if you can change the RAM frequency by changing the "Auto" to manual. Somewhere around in that part of your BIOS you should be able to change it to 1600.

Leave the timings like this:

CL: 9
tRCD: 9
tRP: 9
tRAS: 24
tRC: 33
CR: 1T

You may want to change the Command rate or CR to 2T. 1T can be hard on most systems and cause instability.

Enabling the XMP profile (if it has one, some Hyper-X modules don't) will automatically set the voltage, command rate, IO speed and all primary timings. If the module does not have an XMP profile you will have to set these manually. Failure to set all the settings correctly can result in your system failing to boot.

If I recall correctly, Kingston modules ending with X have an XMP profile

Damn! is it possible to choose 2 best answers here? i'm new to this forum but you guys are all GREAT :bounce: 
looks like battle of the eLites here in this forum..lol..kidding aside

@anort3..yes i can manually change it in my BIOS to 1600MHz, i've seen it, my concern is i don't know how to change the timings or am all good with the same timings/clocks i have above? changing it to 2T? i'm not sure where to do it in the BIOS :(  is that in the same page?

@Pinhedd..how can i go enabling the XMP? i'm using athlon x3 455 so will this support 1600MHz? will it do any harm to my system if i'll do that? sorry i'm not that techie when it comes to computer :sweat:

The Athlon II processors only "officially" support DDR3-1333 which is why your speeds defaulted to that. It may be able to run DDR3-1600, I don't know. I don't have any AMD processors and can't really comment on how reliable they are, sorry.

XMP only applies to an Intel system.

Leave the timings at where they are for now. If you have any strange blue screens or crashes then use your motherboard manual to find where to adjust timings and change the 1T to a 2T. That memory may run fine at 1T.

Also I believe that is 1.65v RAM so make sure the voltage is correct.

It should run it fine. I am actually at my sister's house on an Athlon II X3 440 / Asus board system that I built for her a couple of years ago and it has GSkill DDR3 1600 7-8-7-24 RAM in it running fine.

@anort3...yes i checked the BIOS and it says 1.64v. haven't encountered blue screens so far and yes, i was about to purchase Gskill DDR3 before however, it was out of stock in our store so i settled for HyperX. So should i just it to 1600MHz then change CR to 2T? it won't do harm to system? i'm using Athlon II x3 455 and Asus also. What's you final recommendation then about my memory?

@Pinhedd...no problem man..been a big help...btw any idea of a good cooler?

^ Thats what I would do.


I don't know any good coolers without a backplate. The Hyper 212 + and Hyper 212 Evo are the best coolers for the money hands down but you would have to take the board out. You will have to clean the old thermal paste and replace it as well when you do the cooler and I always find it easier to do a good job of that with the board out. Also lets you clean out your case back to that "new" state if you take the board out.

i was about to purchase it last week however, i change my mind because of how it's installed..i'll go for hyper 212 evo but then again, it is imperative for me to dismantle my system :sweat:  :(  this cooler is only good for OCing right? i'm not OCing my system, so you thikn i have to change my stock cooler?

No. If you are not overclocking there is no reason to get aftermarket cooling. Well the stock AMD coolers are a bit loud but if noise is not an issue for you then there is no reason.

yup..i am not OCing my system, the reason is that i read some posts online that OCing this CPU won't go much so i think i'll stick to what i have then. by the way, i am using Athlon II X3 455 @3.3Ghz and they said OCing this will just be around 3.5GHz. not sure though

I'm not sure. I have not overclocked an AMD system since 2004-2005. I would think it would go to around 4Ghz like the Phenom IIs but I'm not sure.

Given that the X3s are basically just X4s with a defective core and other components disabled it stands to reason that the silicon quality isn't the greatest and might not have the most headroom. Still great value for the money though

There was actually such a high demand for the X3s that a pretty large percentage of them were X4s with a core and some cache I believe it is just disabled. If you could unlock the core and the cache then you had a full Phenom II. Well over half would give you at least the extra core.

Yeah that's true. Intel does the same thing with their chips but they cut them instead of just locking them out. The 3960x and 3930k are actually 8 core chips with 20MB of L3 cache. Two of the cores are disabled along with 5-8 MB of cache. The yields are so low and the chips are so big that a chip with no defects justifies a $2000 dollar price tag

you guys are good. yes, i have X3 but when i unlocked the 4th core, unstable and have other issues as well so i decided not to unlock it. some were lucky to unlock it but mine...i just have to accept the fact that i have 3 cores running since running it with 4 cores is absurd if unstable.
