pekkle88 Posted April 9, 2007 Share Posted April 9, 2007 Count me in as one of the folks with this mobo & memory combo problem. :[pouts: I followed the settings outlined by Jimmy and MSD and it's gotten the system the most stable it's ever been. I'm still experiencing an occassional freeze-up. Memtest86+ reports no errors. Is there anything else to try so that I can eliminate the freezing? Bios Settings: SLI-Ready Memory = Disabled Memory Voltage = 2.085 tCL = 4 tRCD = 4 tRP = 4 tRAS = 12 CMD = 2 Advanced Memory Timings tRC = 22 tWTR = 15 All other settings = auto Thanks in advance for your help! :biggrin: Link to comment Share on other sites More sharing options...
ulio Posted April 9, 2007 Share Posted April 9, 2007 Try this method of testing stability... [1] Install Prime95 and SuperPI (Google them) Run 2 prime 95 with editing the "shortcut properties --> target" to: "C\Program Files\Prime95\Prime95.exe" -A0 "C\Program Files\Prime95\Prime95.exe" -A1 Run Prime95 x2 and SuperPI together. Each of them have different sensitivity to math rounding errors. This combo will max-out your CPU. Watch carefully how soon the error will occur. [2] IF this test combo runs successfully for 24hr, then try Memtest86+. The latter will test almost all your memory blocks. Memtest86+ can be slow due to single threaded nature. If you got a lot of memory installed, it takes a while to cycle through 1 test. ----------------------- Possible Solution: ----------------------- [1] Up the Dram voltage (Vdimm) to 2.1v and use the above test. If you go up further to 2.2v, use temperature measuring device to monitor your dram temp. and keep it below 50C or 122F. A fan will do the job nicely. [2] The problem is most likely to do with Compatibility. It is neither faulty ram modules nor board in most cases. Also run your Dram at 667MHz (333MHz x2). Sad, i know... but that will likely to get things working crippled but flawlessly. Strangely, we have experienced many compatibility problems beyond DDR2 6400 with some boards as well. Oh forgot to mentioned, i got the XMS2 in the lab working at 2.2v but that's unacceptable as it's rated maximum voltage at 2.1v. Increasing the voltage incrementally in our case, do increase the stability. Link to comment Share on other sites More sharing options...
pekkle88 Posted April 12, 2007 Author Share Posted April 12, 2007 Thanks Ulio! I was not able to run two instances of Prime95 without the system going to a crawl (maybe that was the point?). But I ran one instance of it overnight and it didn't error. I ran SuperPI overnight without error. So...I'm hoping that everything is ok for now. If it starts to lock up again, I'll let the group know! :o: -pekkle88 Link to comment Share on other sites More sharing options...

pekkle88 Posted May 17, 2007 Author Share Posted May 17, 2007 System was stable with no OC (stock 2.4GHZ) with Jimmy's memory timings of 4-4-4-12, CMD 2, voltage 2.085, tRC=22 & tWTR=15. Currently, I'm OCed to 3.0GHz: Left the voltage on "Auto" Unlinked the memory & CPU Upped the FSB to 1333 (333x9=3.0GHz) Running Orthos my core temps are about 48C. It peaked at 50C and came back down to 48C. Systems runs well, however, I am getting occassional freezing up of the OS, and I have to hit the reset button to restart the PC. Any ideas on what I should tweak to eliminate this? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 17, 2007 Corsair Employees Share Posted May 17, 2007 Since you are over clocking and the system runs with normal settings you will probably need to adjust some of the other settings like CPU Voltage and or Chipset Voltage.

pekkle88 Posted May 18, 2007 Author Share Posted May 18, 2007 Ahh...but which one? And to what settings? :sigh!: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 18, 2007 Corsair Employees Share Posted May 18, 2007 I cant tell you how to over clock sorry. You might look at some of the over clocking sites, but try increasing the CPU and chipset Voltage just a little one at a time and see if the results change.

pekkle88 Posted May 19, 2007 Author Share Posted May 19, 2007 I did a search of the forums and found TimC's recommendation of not letting the loaded core temp go above 60C, but I've heard others say not to go over 50C. What's the general consensus out there on the max temp you should try and stay below? Also, CoreTemp 0.95 reports a Tjunction temp of 85C. Is that ok?

Garvin Posted May 19, 2007 Share Posted May 19, 2007 http://forumz.tomshardware.com/hardware/Core-Duo-Temperature-Guide-ftopict221745.html It looks like Coretemp is just reporting the max Tjunction value for your particular cpu model. It takes a bit of work to find out what it actually is running at. Link to comment Share on other sites More sharing options...
