Windows 7: RAM timings changes on its on

RAM timings changes on its on

Hi

I have noticed that my RAM's clock speed is being changed on its own and wondering why this is happening since I have manually set the timings/speed & voltage in bios, my RAM is suppose to run at 9,9,9,24 @ 1600mhz, that is what it is set in bios also but looking in speccy & cpu-z the timings is showed as 7,9,9,24 @ 1600mhz. Could it have anything to do that I have overclocked my CPU? its running at 4Ghz 20x200 BLCK. And I am sorry if this have been asked already had no idea what search words to use

Best way to find out if it is due to overclocking is to reset your BIOS to default settings and then adjust your RAM to see if it stays the same. It may also be due to the CMOS having a problem, in which case you should reset the BIOS to default settings to clear the CMOS.

Note, if you are running multiple hard disks in the machine using a RAID controller, clearing the CMOS will reset the controller resulting in loss of data. Backup your files and create a system image before clearing the CMOS if you have a RAID setup.

If you are unsure whether you are running a RAID configuration, do the following steps.
  1. Click Start Menu
  2. Right Click My Computer/Computer
  3. Click Manage
  4. Click Device Manager from the list on the left
  5. Expand Disk Drives and check for RAID manufacturers (use Google or ask us by typing in manufacturers listed in your Disk Drives list)

Alternatively:
  1. Login as an adminstrative user.
  2. Click Start Menu
  3. Click Control Panel
  4. Click Hardware and Sound
  5. Click Device Manager (the last link under Devices and Printers)
  6. Expand Disk Drives and check for RAID manufacturers (use Google or ask us by typing in manufacturers listed in your Disk Drives list)

I know for sure that I am not using raid since I just have 1 hdd, so I will just write down my OC settings and then reset CMOS. But just a question if the computer is running stable and considering that the computer have put that setting to 7 instead of 9 there should be no damage or, the RAM I am using is like 1 day old, but I noticed the other ones I had in before did the same thing but just 1 clock lower then I sat

If you are not having stability problems with the current configuration, and everything runs smoothly, then I would just leave the settings as they are. No need to mess with perfection.

Ok, I will run just to be sure prime95 for some time and if I get no errors I will go to bios and actualy set it to 7 manually

Edit #1: I manually changed that timing to 7 and the computer did not wanted to boot then, so I see if it does it again and then reset cmos

Ok, I find this funny but it happens after I put the computer to power saving mode, thats when it changes to 7. So is it possible there is something else that is wrong? that windows is just reporting the wrong numbers when it actually is at 9

It is possible it is a Windows issue. I do not know whether it is misreading the value, or if power saving mode actually changes it. It could be your motherboard has some power saving settings that interface with Windows to allow for power conservation. Do you get any noticeable performance drop during power savings? If not, I would just ignore it.

I notice nothing in windows as all, and all my power saving and those C-state are turned off in bios. And since it only "changes" after I wake the computer from power saving mode and that I have manually filled in the ram settings it must be a windows issue right, but I will run prime to actually see if something is wrong and if I get no errors it must be windows that is reporting the timings wrong

Sounds like a good step. Let us know how prime95 goes. Run all three tests for a few hours each and post back how they did.

I ran the blend test that test a lot of RAM for 1 hour and 10 min and it gave me no errors or warnings, and since I have tested to actually set that clock to 7 in bios and the computer refuse to boot that way I really do believe that this is more of a windows 7 issue since everything runs fine.
