DDR3-1333MHz runs at 400MHz

[Pierlowie]

Hi everybody,

I've been browsing the forum a bit and tried some stuff out but in the end, my problem is not fixed.

So, let me start with the problem: When I run AMD system Monitor, I can see my System Memory Speed is
at 400MHz instead of 1333 MHz,
screenshot:

I've got an EX58-UD3R motherboard and i7-920 processor.

Some CPU-Z info can be found in the next screenshot:

I've updated my bios and switched some values around but the speed doesnt change in AMD system monitor.

So, my question: Any one has an idea what the problem is and how to fix it?

Thank you in advance!

Your RAM is no issue its normal
1333mhz isnt real speed
Real is half of it

 

[Pierlowie]

Well, I know the 'real' speed isnt 1333 mhz, but i got friends with the same computer as me and when they run amd system monitor, they got a system memory speed of 1333 and I can give you an example why i thought something was wrong with my memory/pc: I used to play a game named Heroes of Newerth (HoN) and when I and me friends enter the game, load the game and then requeue, so reload the game, for me the loading time is about 3x as long.

So, in my opinion, something is wrong.

Theres nothing wrong with your ram imo check cpuz in your friend pc and check is it 1333mhz or 667mhz

 

[THE UNKNOWN]

N if your not sure check BIOS RAM FREQUENCY and set it to 1333mhz

 

[scout_03]

ajust bios setting to 1333 ram should show this speed with system monitor

 

[Pierlowie]

Well, i've had it on 1333mhz before and in system monitor it was 400 Mhz, that's why i've changed my RAM to 1200mhz, to see if it changed, but it stays @ 400, i've done a memtest86 for 6 hours and indeed, nothing is wrong with it. But I just found it strange that my loading times from the cash was so slow and that AMD system monitor says 400mhz and 1333 with others. Oh and maybe this indicates a problem too, when i start SIW and go to memory, it says Wrong values reported by BIOS. I've searched that up, and yes, the awnser is, look at CPU-Z, that should be correct.
But still, i have a feeling my ram is slowing my pc down.

But I want to thank you for the replies already!

i would check on stick at the time to see if they report good speed in the amd system monitor use this to see what memory speed it read it's free http://www.hwinfo.com/

 

[mouse24]

^ if that doesn't work try overclocking your FSB just a very minor amount and see if it changes the ram speed.

 

[Pierlowie]

So, I have downloaded hwinfo and idd, my memory runs fine (screenshot link: http://i463.photobucket.com/albums/qq352/Pierlowie/HWinfo_mem.jpg ), so, perhaps nothing is wrong at all, just a strange 'bug' at amd system monitor and perhaps a problem with HoN.. not sure.. But thanks again.

link told me page not found just post it here

 

[Pierlowie]

i've updated the link, but here is it

 

[scout_03]

i been looking at your motherboard specs they all use dual channel and you got triple channel memory that could cause false readings

 

[THE UNKNOWN]

As i already told there's nothing wrong with you ram

 

[scout_03]

remove one stick and you will get exact readings

 

[scout_03]

remove one stick only use 2 and you will get exact readings

 

[Pierlowie]

This is what i did: i've removed 1 stick, so i had 2 sticks in dual mode, the reading was 400Mhz, removed an other stick, so only had 1 stick, reading was 400 again.
Then I removed 2 of my fathers sticks and replaced it with my memory, with his ram in my computer, i had a correct reading.
Then I put my RAM in his computer, he has a correct reading too. But when i put my ram in my computer, i goes to 400 again :/ it's strange.
I was stupid not to test the game 'HoN' to see cash loading difference but i will do this wednesday since I have no time tomorrow.

 

[scout_03]

when you got 2 stick of your inside your mobo did hwinfo report them dual channel at the right speed

 

[Pierlowie]

Yes, HWinfo reported dual channel and a clock of 667 (x2) BUT today, I did find something.

Here you can see my Memory speed is at 400Mhz,
If you look at your settings, i dont think it will be 400.

 

[THE UNKNOWN]

Remove all sticks clear cmos after that clean sticks carefully
put them again in slots but not in blue default your bios

 

[mouse24]

I doubt cleaning them would help, Hmmm, have you updated your Bios to the latest revision?

As for your query about the ram slowing your pc down, nope not a bit. changing from DDR3 800Mhz to DDR3 2133 is only a change of say 5 nano seconds.

I'm still using DDR2 800 Mhz simply because I had it on hand and wanted to save 50 bucks.

The only real reason I personally would upgrade to DDR3 is if I needed more ram or was building an entirely new system.

Hope that helps a bit.

O saw a benchmark that stated a change from 800 to top end 2100 was a frame difference of less then 1fps (which of course can be simply benchmark fluctuations)

if you look at the picture of cpu-z on the post your refresh cycle time (tRFC) is never the same try to it manual to 34 as suggested in cpu-z and hwinfo then report the first page of hwinfo and then the cp-z memory page

 

[Pierlowie]

@ The Unknown: I've cleared CMOS, cleaned RAM's and loaded optimized settings, still 400 MHz

@ Mouse 24: I've updated BIOS to latest version I can update since the last one says file to big. And I was searching a reason why my loading times of the game HoN is so much slower then others with alot less good computers. But seems like RAM has little to do with this (eventho the data is saved and loaded from the cash?)

@ scout_03: Tomorrow I will manual put the tRFC to 34 and report the first page of hwinfo and cpu-z memory page

Thanks for the help!

 

[scout_03]

be around for the result

remove all components including cpu carefully then rebuild them
