Coffinwizard Posted November 20, 2007 Share Posted November 20, 2007 Hi, My first post here, unfortunately regarding a problem. After reading many threads, I decided to post my probleme here, as I beleive RAMGuy can help me - if he has the time. Here is the configuration I have: Motherboard: Asus P5KR Proccessor: Intel E6850 Core2Duo Memory: 2 kits of Twin2x2048-6400C4DHX (4 modules of 1GB each) The status of the system now: Install of XP SP2 went on without problems. Browsing the computer, installing programs, burning DVDs, etc. is going on without any issues. I went on doing some tests using nVidia system stability program, 3dMark05 build 110 and BurnIn Test. None could be completed. Either the whole program would exit without displaying any message or the system would freeze, reseting it being the only solution (freezing occured at every test using BurnIn - testing 6 components in the same time: memory, 2d, 3d, hard, cpu math and cpu ssx(?) and in 3DMark in 50% of cases; the system never freezed in the nVidia stability test, it just closed). I ran only the memory test in BurnIn at 100% usage - it game me errors in the last three minutes of testing. First thing I did is run MemTest 1.70. It displayed errors after about one hour of tests. I removed the modules in slots A2 and B2 (as the motherboard manual indicates that if using two modules, use A1 and B1). I ran MemTest again - no errors. I ran the above mentioned benchmarks again, all ended normaly and displayed results. I believed that the modules removed were the problem but I wanted to be sure. I installed them back, replacing the ones that I left in. Again ran MemTest - no errors :bigeyes: Went in XP, running the benchmarks and again they all finished without any problems. At this time I was very tired (5-6 AM) and decided to leave MemTest running with 4 modules again while I slept. When I woke up no surprise when the screen was full of errors. Now I am in the process of testing each pair of modules separately, on each motherboard channel (A1-B1 and A2-B2). I am now at the second pair of modules and no errors. I beleive that I will have no errors and everything will be fine. What I would like to know is how to make the system run with 4 memory modules of 1GB each. All BIOS settings are on manual. If this is the problem, I would like to know exactly what I have to change because there are a lot of things in the BIOS settings which I am not familiar with. I thank you in advance and I hope someone can help me. Link to comment Share on other sites More sharing options...

Coffinwizard Posted November 20, 2007 Author Share Posted November 20, 2007 Hi, Thanks for your very quick response, I will try the settings as soon as I get home (60 minutes). In the first post I made a mistake, I wanted to say that all settings in the Bios are on Auto, not on manual as I wrote. I hope this doesn't make a big difference. Your answer I believe would be the same in both cases. I hope it will resolve my problem. Thanks again for your answer. I'll let you know the results. P.S.: The tests ended without errors for all modules, as predicted Link to comment Share on other sites More sharing options...

Coffinwizard Posted November 20, 2007 Author Share Posted November 20, 2007 I also wanted to ask and I only now realised :-P The memories can't run as DDR2-800 on this motherboard? I mean all the 4 modules at the same time? This is why you told me in your post to set them as 667? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 20, 2007 Corsair Employees Share Posted November 20, 2007 Yes more or less, with 4 modules there is more loading on the system and it is common to have to slow the memory down to make the system stable.

Coffinwizard Posted November 21, 2007 Author Share Posted November 21, 2007 Hi, The system is still running :) I'm going to do the tests now. There are some things I left on Auto, I didn't know what values to put: RAS to RAS delay Row Refresh Cycle Time Write Recovery Time Write to Read Delay Read to Precharge Time All 5 above are from the DRAM Timing Control section, all left on Auto. Continued: DRAM Static Read Control Transaction Booster Clock-Over Charging mode All above left on Auto too. And one more thing - you said to give +0.5 Volts to the NB/MCH Chipset. I only have these options: North Bridge Voltage - was on auto, I set it on 1.25V (other options: 1.40, 1.55, 1.70) North Bridge Voltage Reference - it's on Auto (other options: 0.67x, 0.61x) If there are some options that I still have to change, please tell me. I'm hoping that the tests will work without any further changes but just in case... Thanks again for the help. Link to comment Share on other sites More sharing options...
Coffinwizard Posted November 21, 2007 Author Share Posted November 21, 2007 All test ran fine with the settings mentioned in the above post :D Only one little thing, I don't know what to make of it: after 9h30m of MemTest (while I slept), at the 15th pass (out of a total 17) one error appeared (yes, just one): Tst: 7 Pass: 15 Failing Adress: 000ab943e20 Good: 0489eb8b Bad: 0689eb8b Err-bits: 02000000 Count: 1 The test was made with all 4 modules installed. When I woke up, he reached pass 17 and was still going. I don't know what so say about this error. Is it isolated? Is it caused by the memory or still by the motherboard?

Corsair Employees RAM GUY Posted November 21, 2007 Corsair Employees Share Posted November 21, 2007 What are the exact system spec's and can you tell me the exact BIOS settings you had set for both CPU and memory? Link to comment Share on other sites More sharing options...
Coffinwizard Posted November 22, 2007 Author Share Posted November 22, 2007 System specs: Motherboard: Asus P5KR Proccessor: Intel E6850 Core2Duo Boxed Memory: 2 kits of Twin2x2048-6400C4DHX (4 modules of 1GB each) Video: BFG 8800GT PSU: ThermalTake PurePower 600W W0144 Storage: 2xSeagate 320GB + Lite-On CD-RW + Lite-On DVD-RW Case: Antec P182 I don't think you'll need the exact models for the HDDs and optical units. I don't know them by heart and I'm not home right now. If you need them, no problem, tell me and you'll have it. About the Bios settings, I'll take a picture of the Bios screen and post it so you can see the whole picture. This will happen unfortunately in about 5 hours :( Link to comment Share on other sites More sharing options...
Coffinwizard Posted November 24, 2007 Author Share Posted November 24, 2007 The long awaited BIOS settings, in the pictures attached :) Link to comment Share on other sites More sharing options...
DerekT Posted November 24, 2007 Share Posted November 24, 2007 I would set your DRAM Voltage to 2.1V, NorthBridge Voltage to 1.3v and retest. Link to comment Share on other sites More sharing options...
Coffinwizard Posted November 24, 2007 Author Share Posted November 24, 2007 I can't set NB voltage to 1.30, as I wrote in an above post which are my options: 1.25, 1.40, 1.55 and 1.70. The motherboard now has an idle temperature of 39 and in full load it has 42 (before I did the voltage change it had 36-39) and I don't know if it's a good ideea to increase the voltages again, as the recommended temeperature is 50.

DerekT Posted November 24, 2007 Share Posted November 24, 2007 Set to 1.4v and test. The view that 50C is maximal is incorrect. The tcase for your E6850 Core 2 Duo is 72.0C. Throttle is at 80C. Below is the thermal specification for Intel's Core 2 Duos, Quad Cores. Look to your CPU and you will find: http://www.intel.com/cd/channel/reseller/asmo-na/eng/products/desktop/processor/processors/core2extreme/tech/299986.htm E6850 = Maximum tcase (C Degrees) 72.0C @ 65Watts. If you are speaking towards the Northbridge temperature, then 50C is a walk in the park. Link to comment Share on other sites More sharing options...
Coffinwizard Posted November 25, 2007 Author Share Posted November 25, 2007 I will do the test, I was decided to even try with the modules set to 800 not 667. Regarding your last answer, I was not reffering to the CPU temperature. I was reffering to the motherboard temperature, as indicated by ASUS Probe. I knew the CPU limits and I have no problem with those. The ASUS Probe has a default setting for triggering the alert set at 50 degrees for the motherboard and 65 for the CPU. I was reffering to the 50 limit, which I'm getting close to, due to increasing the voltage. Link to comment Share on other sites More sharing options...
DerekT Posted November 25, 2007 Share Posted November 25, 2007 I always remove the Northbridge heatsink to ensure proper thermal paste is installed, and that the heatsink is sitting flush on the chipset. Often only a portion is touching and this is unacceptable. If you are an able hardware enthusiast then I suggest you do the same. If you are not, then it is best to leave it alone.

Coffinwizard Posted November 26, 2007 Author Share Posted November 26, 2007 I will do that too, thanks for the advice. I cannot call myself a "able hardware enthusiast" but I build computers for some time now and I don't think that checking the heatsink would be a major problem. I will let you know hao the tests went and also how the thermal paste looks like. Also another thing I wanted to ask, you and RamGuy work toghether? :-P I'm asking because I saw you both answer posts but in the beggining only RamGuy answered mine and I didn't really know what to do when you asnwered too (meaning that I didn't know if you followed the whole "story"). Thanks for the help, both of you. At the moment the system doesn't have any problem, all benchmarks run fine, no problems in programs/games/movies etc. I don't even know if the difference between 667 and 800 is noticeable (if 800 works).

DerekT Posted November 26, 2007 Share Posted November 26, 2007 RAM GUY is the "Go To Guy" He deals with every DRAM issue on the entire forum and the rest of us try to help in our own way so that he can stick to the DRAM issues and RMA, etc. If events occur that we can't help with, then he will come in and fix it up. I just come in and help out because when I had issues and came here, RAM GUY helped me and dealt with all my problems. So I try to repay in some small way. He isn't here now because, as you said, you have no DRAM issues. I understood that when I mentioned the Northbridge. This is not a DRAM issue and is a motherboard issue.
