RAM Problem


Daza07

Recommended Posts

First of all I have installed the RAM (TWIN2X2048-6400C4) in the two yellow slots as indicated in the motherboard's (ASUS P5k-E/Wifi BIOS 503) manual. I decided to use CPU-Z (v1.41) to check if the RAM was working at it's correct values. It isn't so then I looked at the packaging of the RAM and noticed there was a website on the back so I went to it. I got on the site and checked what the values should be so I went into the BIOS and changed it to what it is supposed to be (4-4-4-12) because before the timmings was 5-5-5-18 on Auto. I also changed the voltage to 2.1 and set the RAM Mhz to 800 but still the problem persists.

 

Thanks

The SPD for these modules is programmed to run at 5-5-5-18 at 1.8 volts, this is why that is showing up in your SPD tab. By default the motherboard will load the SPD. These modules are tested to run at 4-4-4-12 at 2.1 volts, these settings will need to be set manually, and the actual settings that the memory is running at will be shown in the memory tab.

In my last post I wrote that I did change it manually and yes the ram is running at the correct values. The memory tab in CPU-Z confirms it.

 

My question is now that the RAM isn't running at 800Mhz as shown in the attachment also it says one of my RAM sticks have a different Part Number as displayed by CPU-Z.

I am sorry but yes it is according to the Image you posted.

 

DDR1 Memory runs at:

DDR-266 = 133 MHz 2 X 133 = DDR-266 PC-2100

DDR-333 = 166 MHz 2 X 166 = DDR-333 PC-2700

DDR-400 = 200 MHz 2 X 200 = DDR-400 PC-3200

 

DDR2 Memory runs at:

DDR2-533 = 266 Clock Frequency 2 X 266 = DDR2 533

DDR2-667 = 333 Clock Frequency 2 X 333 = DDR2 667

DDR2-800 = 400 Clock Frequency 2 X 400 = DDR2 800

DDR2-1066 = 533Clock Frequency 2 X 533 = DDR2 1066

 

Intel CPU:

400 MHz = 100 MHz Clock Freq. 100 X 4 = 400 FSB

533 MHz = 133 MHz Clock Freq. 133 X 4 = 533 FSB

800 MHz = 200 MHz Clock Freq. 200 X 4 = 800 FSB
