Please Help Me With System Freeze Ups


Derek Smalls

Recommended Posts

Hello All,

 

I keep getting random freeze up when using the equipment listed in my spec list.

The BIOS settings are set to default for the CPU and Memory, I've ran the MemTest v4 with all 4 sticks in place for about 2 hours with no errors.

 

Could anyone advise what memory settings I should use to have a thawed out system ?

 

 

Thank you for any help.

One thing ive learned from experiance is that different size harddrives can cause it.Just a thought thou.

I have three different size hard drives in my computer; I don't think that would cause the system to lock up. If there is a software problem it may cause the operating system to crash; a locked up computer caused by hardware issue like a memory or CPU problem has nothing to do with any of the hard drives.

Thank you for your replies.

 

The MoBo, CPU and Memory were all bought before Xmas.

And I tried to do a clean install of Windows 7, but for some reason I couldn't get Windows to install, it just kept hanging after the first reboot.

So I bought a new HDD (Maxtor) from a local store, I tried again, but I had the same results, so the store swapped the HDD for a replacement.

But I still had the same problems.

 

So I replaced my Thermaltake 750w PSU with this one about 2 weeks ago.

And I could install Windows 7 without any problems, no hanging etc.

 

But I did notice, that Windows would just pause/lock up/freeze (whatever you call it) at random, sometimes it was doing nothing, something I was clicking on the Start menu or other times trying to install software.

The Power Settings in the Control Panel were set to High and everything is set to remain "On".

I've also tried a different graphics card (BFG 7800) and had my 8800GT checked over by the manufacturers.

 

I do reboot often, so it's not like my PC is on for days without rebooting, but I've recently noticed it seems to freeze more in the evening/night when it's been on longer.

Restarting the PC sometimes has no effect, it freezes up straight away after coming back on and can even freeze up if I choose to do a "Repair" of Windows.

The only way to make it usable again in this situation is to remove 2 sticks of memory and just use 4GB's (in the correct slots).

But in "normal" random freeze ups, I can just reboot (CTRL, ALT, DEL does nothing) and keep using the computer.

 

The reason I use 8GB's at all is for photo work i.e. Photoshop and NX2, no games.

 

Edit:

I forgot to add, my case doesn't have an inbuilt speaker, so I can't hear any MoBo beeps.

Please list all of the settings you have made in the BIOS for RAM, CPU, and voltages.

 

Also, just so I am clear, did you get a clean install of WIN 7?

All the BIOS settings are default, please see the 7 screen shots below.

Yes, I did a clean install of Windows.

Try 1.15v - 1.25v on the QPI VTT. This is your memory controller voltage. In some cases you need more volts here to run 4 modules as opposed to 2 modules.

Thank you very much Sir. So far so good.

I've adjusted the figure to 1.25v.

If I get any problems, I'll back it down to 1.15 and slowly increase it if needed.

 

Thanks again, I doth my internet cap to you :D:

If you are feeling like doing some testing, I'd start at 1.15v. That is the setting in our XMP profile for 4 modules at 1600 so it should do your frequency with 1.15v to 1.2v. But, 1.25v is not unsafe.

 

Glad to help! ::pirate::

I was part way writing my reply to you saying that I'd set it back to 1.15v and would follow your advice, when my PC froze :roll:

So I've set it to 1.21v as a compromise.

 

Thanks again :praise:

I'm still getting freeze ups :mad:

 

I started off a download through the night, with the voltage setting at 1.21

But when I checked in the early hours, it had locked up, so I set it to 1.25v

When I checked again later it had locked up again.

I then cranked up the voltage to 1.51 (as also tried 1.49) but it still randomly locks up.

As mentioned here:

I've run the MemTest v4 for 3hours with all sticks attached and it finds no errors.

I also ran the Windows error check and it finds no problems.

 

Is there any other memory settings I can adjust ?

Thank you.

Based on what you are posting, I don't think the memory or any memory settings are the issue.

 

Try 1.25 on QPI, 1.6v on memory. If that fails, just for testing purposes, see if you can get 2 modules of the 4 stable. If you can, try again with the other 2 modules.

I've ran my system for the past hour with the changes you've suggested.

And so far it seems stable :D:

 

Thank you very much.
