BIOS timing differs from cpu-z?


below90hz

Recommended Posts

I just found out this weekend that my RAM timings were probably not at 2-3-3-6 like they should be, so I went into the BIOS and sure enough, they were 3-4-4-8. So I changed them to 2-3-3-6 and saved my settings and got back into windows. Cpu-z confirmed I changed my timings, except it's reading them at 2-3-3-8. I triple-checked to make sure I did everything right, and everytime I got into the BIOS it showed that I had saved my settings correctly. But cpu-z does not show that. Anyone know why that might be?

 

Motherboard: Gigabyte GA-K8NF-9

Processor: AMD Athlon64 X2 4400

Memory: CMX512-3200C2

 

Thanks, Ethan

Please post a graphic of your CPU, Memory and SPD tabs of CPU-z.

 

Thanks

 

Okay, first lemme say I forgot for my AMD system the CAS latency is supposed to be 2.5 I think, not 2. So that's what I have it set to in the BIOS: 2.5-3-3-6

 

Thanks for your help, here's the pics:

Try setting to this. Does your CPU-z show a difference?

Well I didn't see any settings called "K8 CPU Clock Ratio" or "DDR Clock/Timing Ratio" or "Top Performance" in my BIOS. But I did change the voltage and the timings to what you specified and still no change. However I noticed that the Bank Cycle Time (Trc) changed from 11 to 12. :confused:

 

I am getting two new 1gb sticks of XMS ram this week. My current two sticks of 512mb ram are sitting in slots 1 and 2. Before I install all 4 DIMMS, should I pop the new ones in slots 1 and 2 by themselves and see if they hold the settings? Are there any other options I might try?

First of all, you might find yourself with quite a few problems with that board and all four slots filled. Be ready for the possibility of grief.

 

You need to turn your system off. Remove the power cord. Look for the CMOS_CLR jumper and set it to clear your CMOS. Press your Power On button for ~5 seconds. Reset your CMOS_CLR jumper and install your ram. Use the largest ram first and the smaller size last in your motherboard's dual channel configuration. Most are Dimm0 & Dimm2 with the second dual channel being Dimm1 and Dimm4 (or Dimm1 and Dimm3 / Dimm2 and Dimm4). Check your motherboard manual for the proper placement in Dual Channel modes.

 

Restart.

Okay thanks for all the tips. I will use them, except what's quoted above I'm not sure how to do. I assume there is some sort of physical connection I need to remove on the motherboard, and then put the jumper back in place. But I have no clue what it would look like or how to go about doing that. I will consult my manual like you suggested, hopefully I'll be able to figure it out.

 

If things go badly like you suspect, can you recommend any good mobo's for an AMD X2 chip? Again thanks for all your help!

Here is an easier method although it is a bit more time consuming.

 

Remove your Power Plug. Open your case. Look for the small round battery and remove it. Leave your system this way for a few hours. After a few hours, press your power button and hold it for ~5 seconds.

 

Replace your battery. Replace your Power Plug. Restart the system. Set your time, save default settings and restart.

 

Then enter your BIOS and set to the settings I gave you. Do you have a link to the exact manual of your motherboard or can you set down the exact settings as apply to the Intelligent tweaker?

 

Thanks
