Hello, latelly i've been trying to overclock my cpu(Q8300) and DRam(Corsair ddr3 1600Mhz). I have set my FSB in bios to 400 mHz, Cpu ratio at 7.5, enabled FSB strap to north bridge at 400mHz and set my DRam frequency to 1600mHz. I didnt adjust anything else. Computer seems to boot up fine, but after some time (arround 30 minutes) i get blue screen because computer crashes. Also it wont let me reboot until computer was turned off for about an hour. I think that has nothing to do with temperatues bacause, they're about 40-50C. Anyone has an idea what could be the problem?
Maybe im doing something wrong? :)

PS: Motherboard: Asus P5P43TD PRO

:welcome: Vainius

The symptoms and the 1 hour delay before being able to reboot the computer are classic signs of overheating, the 40-50C temps are fine if they are the CPU temps but there are other items of hardware that can overheat which you cannot always monitor, this includes the Ram and the PSUs internal components.

Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

(this is a screenshot from a vista machine)

To capture and post a screenshot;

Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.

Depending on the results we may need to run further software for comparison http://www.cpuid.com.../hwmonitor.html

Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

Thanks for the reply, here are my results. Screenshot was taken about 2 minutes till blue screen. Maybe it's happening because I had to configure voltages also? Also my PSU is pretty weak(only 400W) :)

Thanks for the screenshot which shows that your PSU output (voltages) are ok which is a good start, your temps are creeping up but are not high enough in the screenshot to cause the system to crash.

What I suggest that you do next is restart the computer and go into the BIOS, select the default settings option, press F10 to save the settings and then Y to accept the changes, once you have done this use the computer as you normally would and see how it behaves.

If this resolves the issue we can look at improving your cooling fan settings and improving the system performance without pushing things too far.

Couple of questions if I may;
What is the brand and model name or number of the PSU and the same for the video card please.

You are welcome BTW :thumbsup:

Codegen is not the best of brands but it is obviously not the cause of the issue so I would stick with the default settings to avoid further problems and a possible complete meltdown.

Just a bit more info for you, the video cards power requirements can be found @ http://www.geforce.c.../specifications

PSUs to trust and avoid http://www.10stripe....d/psu/brand.php and http://www.pcmech.co...ide-inside.html

One more interesting thing. I could even push my FSB to 440 and it would work fine with no crashes, but when I also set My DRAM frequency to 1600 MHz it starts crashing. Maybe has to do something with DRAM timing?
Or maybe Buying new PSU would help as overclocking requires more W power? :)

Edit: When I get BSOD it says memory management 0x0000001a.

Sorry but my knowledge of overclocking is limited I`m afraid with helping to put it right when it has gone wrong about as much as I know.

See if the attached link helps http://www.geekstogo...w-to-overclock/

Purchasing a new PSU will not enable any hardware to function outside of it`s stable parameters BTW which is what the error messages are telling you is happening with the memory.

Solved!
Changed my Corsair CML 16GX3M4A1600C9 16GB of RAM to A-data DDR3 2000G 4gb. everything works like a charm even on 440 fsb. :)
Although Corsair worked without any issues on 1333mhz also. Maybe, they're not overclockable.
So, one more question, should I keep a-data 4 gigs with overclocked CPU and RAM or change back to 16 gigs of Corsair and stay with stock settings? :)

For the best and most stable performance you should where possible use Ram that have been tested and approved by the motherboard manufacturer, this is referred to as the QVL ( qualified vendors list ) understand though that there are too many products released for them all to be tested so other hardware will be compatible but not proven to be.

Your MBs QVL http://www.asus.com/...RO/#support_QVL

You will note that the fastest Ram tested is 1600MHz so it could be the MB that is restricting you, what speed is the A-Data Ram running at.

How does the computer behave with only 8GB of Corsair fitted.

NB: Unless you are editing video, doing CAD or 3D modelling work you will not need or use any more than 8GB of Ram so if 8GB of the Corsair works ok you could consider selling the additional 8GB.

Check the Newegg feedback tab and you see many users of the Corsair Ram reporting that it was auto detected by their MBs as 1333MHz http://www.newegg.co...N82E16820233197

A-data 2000g is running at 1400mhz now.
Sadly, with 8 gb of corsair it keeps crashing. im thinking of keeping those corsair RAM for my upcoming build with AS ROCK Z77 Extreme4 which is well compactible with these RAM.

Is this the same A-Data Ram but only 1X4GB stick.

A-Data Intros 8 GB XPG-Gaming DDR3-2000 Dual-Channel Memory Kit
A-Data expanded its XPG-Gaming Series V2.0 series with a new 8 GB (2x 4 GB) dual-channel DDR3-2000 MHz kit. The modules are capable of DDR3-2000 MHz speeds with DRAM timings of 9-11-9-27T and module voltage of 1.55~1.75V. They make use of 2 oz. copper PCBs and aluminum heat-speaders making use of Thermal Conductive Technology (TCT). A-Data's new kit is backed by a lifetime warranty.

The A-Data Ram should run comfortably in your MB at 1600MHz (see specifications) http://www.tigerdire...p?EdpNo=6600774
