From time to time my system will lock up in games (WoW, Civ V)
 
Hope someone can help me.  Suspect my setting may play a role.
Just flashed the BIOS to the latest from this forum P10.

Thanks for the quick reply.
 
I have adjusted all settings to match the values you posted.
 
Now I'll download that memory test program I seen mentioned in another thread and see if I can figure out how that works.
 
Again, thanks for the help!

Think I may have hit a heat issue.
 
1) Adjusted all setting to match post.
2)  started up... browsed around and download mem test.  bootable cd version
3)  burned cd  (10 min elapsed up to now)
4)  started up mem test  system shut down.
 
tried to restart.  wouldn't
 
waited about 2 min.  started up for a couple sec and shut down.
waited about 15 min.  started up long enough to load defaults.
 
Guessing.. over heated.
 
Questions:
Should I modify some of the settings you recommended?
How do I monitor temps during memtest?
I have everest.
My current temps are
motherboard 95 F
CPU     127 F
SPP 136 F
MCP  153 F
GPU 122 F
GPU1 memory 108 F
GPU1 GPU Ambient 109 F
GPU2 GPU 111 F
GPU2 memory 97 F
GPU2 Ambient 100 F
Drive 106 F
 
Cooling fans
GPU1 40%
GPU2 40%
 
 

Motherboard 36 C
CPU 61 C
SPP 58 C
MCP 69 C
GPU1 GPU 50 C
GPU1 memory 43 C
GPU1 Ambient 43 C
GPU2 GPU 45 C
GPU2 memory 37 C
GPU2 Ambient 39 C
Drive 42 C
 
GPU1 40% fan
GPU2 40% fan

Truthfully I'm not sure if they are ideal temps or not.
 
I have a thermal take big water cooler.  For the CPU.  and quite a few fans in the case.  The water cooler never seemed to impressive to me.  I was thinking of changing to a Prolimatech Megahalems CPU Cooler and a different more dependable RAM.
 
Do you have any recommendations on either the RAM or cooler?

Are those your temps with nothing running...as in sitting at your desktop screen?

Windows + Everst + MS Outlook + Internet Explorer.
 
Basically yes.  Not much going on.

As far as the MCP/SPP, I would change the thermal grease on the motherboard heatsink, which is held on by screws through the bottom of the motherboard.  Are you using the small heatsink fan that came with the board?

After dinner I can take a look at the Bigwater and try to remount it.  Could swear it is right.  Perhaps it needs new grease.  It never seemed like very much fluid moved.  Wonder if it ever really worked.
 
As to the above.  I am not sure.  Can you show me a link of what this would look like?  I may actually not have one at all.  The case has a lot of fans on it.  It is a thermaltake speedo.  Perhaps its been screwed up all along cause I don't remember installing a MCP/SPP heatsink at all... but then again.  not knowing for sure what it looks like precludes me being certain.
 
 

OK some progress.  The water level was way too low.  I've added water and worked out all the air in the hoses.
CPU temp is now holding at 37 C - 38 C.  Big difference.
 
Also, I do not have the other fan.  Would you mind giving me a link to where I can buy one?
 
Back to family time.  Thanks for all your help!

I found this info about your current RAM from OCZ website:

1600MHz DDR3

CL 7-7-7-24(CAS-TRCD-TRP)

XMP Profile 1: 1600MHz 7-7-7-28*

XMP Profile 2:1777MHz 9-9-9-31

Available 2GB and 4GB D/C kits

Unbuffered

Intel® Black XTC Heatspreader**

Lifetime Warranty

1.9 Volts

2.0VEVP**

240 Pin DIMM

If you are considering trying some different RAM, I recommend these that I am running: http://www.newegg.com/Product/Product.aspx?Item=N82E16820220285
 
Download this MemTest image file: http://www.memtest.org/download/4.10/memtest86+-4.10.iso.zip
 
Download ImgBurn here to burn the file to CD...manually set the program to burn at the slowest speed:

Those are good temps.  I would try the heatsink fan blowing the opposite direction and see which way gives the lowest MCP/SPP temps.  By the way, did you replace or reapply  the thermal pads on the portion of the heatsink that covers the MOSFETS (beside the CPU)?

It is perfectly fine to reinstall the ones that were already there as long as they were not torn or shredded.  They do not need thermal grease.  The important thing is to not run the board with no thermal pads at all on the MOSFETS.  Best Buy probably won't have Thermal Pads...you would have to get them on line, but since you reused the ones that you had, there is no need to get any.
