Re: Irql_less_or_equal

Not enough info to help you much — you don't even specify the OS.

Did you move the system from another board? If so you may need to run a system repair.

Thanks for the help guy`s ..

Re: Irql_less_or_equal

You memory is not stable, adjust the mem timings looser and/or add more Dram V /MCH v

Re: Irql_less_or_equal

I would suggest running Memtest86 on each stick of ram first and go from there.

Re: Irql_less_or_equal

Thats exactly what I did when I first bought this motherboard guy`s memtest after memtest..all ok been running fine...then all of a sudden BSOD city!..The microsoft guy who came into my comp had a really good browse round and could only suggest a software or virus problem nothing in the hardware was worrying him in the slightest!..I will have another couple of days testing the memory again and see what becomes of it ,,I thought you guy`s might have come accross this with being into gaming and overclocking!I thought straight away that it was memory with it being IRQL prob ...I will give the memtest some hammer and find out!..thanks gain for the advice guy`s!

Re: Irql_less_or_equal

Check to see if any 2 things are sharing the Same IRQ, as that could be your issue also. Try the reassign thing in BIOS

You dont mention what if any additional hardware/cards you are using

Re: Irql_less_or_equal

This is often caused by Memory errors or incorrect voltages. When you ran memtest, did you use Memtest86+? If not, I do suggest you use that, here is the latest >>>

http://www.memtest.org/#downiso

And either test each stick one by one, or one at a time. One at a time would be best, but you may only need to do that if you have errors with all installed.

Auto settings in your BIOS will be wrong for 8GB of ram for sure, so if you are using Auto then that may be part of your issue. Still best to test your ram before you go any further. I see you say you did, but not for how long or with what tests. I suggest the above program and for you to run 5-10 FULL Passes

Re: Irql_less_or_equal

cheers lsdmeasap..will give em another go mate!

Re: Irql_less_or_equal

Let us know how you get along, and if you have no luck please post me a link to your ram and then I can best advise you about possible optimal BIOS settings you should be looking at using. If you do not have any luck, please do give me your settings you are using now that fail and I will advise back >>>

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

Hi again lsdmeasap....here is a copy of the link to the settings you gave me before mate I have not changed then at all they are exactly the same as i posted to you then mate...


..Here also is a link to the Ram I have installed..I have 2 sets of this 4 X 2gig sticks=8gig of DDR2 corsair dominator @1066 mhz..

This is turning in to an epic mate init ?...lol

Thanks again for your time and help guy`s ..

Re: Irql_less_or_equal

Well you should have just posted your settings exactly here again, doing what you did only confuses me and possibly others later who may look here for help.

Did you ever Test your Ram one stick at a time to be sure you do not have any faulty sticks? If not you should, at stock set speeds, and voltages manually set proper. Run Memtest86+ for 5 passes on each stick one by one >>>
Memtest86+ - Advanced Memory Diagnostic Tool

As for your settings, what you linked to is way off from what you should be using. The timings I gave you in this Post #7 is what ranges you should be using >>

http://forums.tweaktown.com/f69/hi-everyone-my-first-post-so-please-gentle-29157/#post274674

If you are or are not, after you do your single stick tests and find all ram to be good please do post here your exact settings you are using that are failing and I will see what I can advise you
