inanitas Posted November 24, 2008 Share Posted November 24, 2008 Hello I have similar problem with my RAM: TWIN2X4096-8500C5DF and ATI Radeon. When I play COD4 or other 3D games they crush. Could you advise me what settings I should chose in BIOS to get it stabilized? I've got Gigabyte Motherboard GA-EP45-DS3R, ATI Radeon HD4850. I am listing BIOS settings below - so far everything is in Auto Mode, RAM voltage 1.8 (also Auto) (G)MCH Frequency Latch System Memory Multiplier (SPD) Memory Frequency (Mhz) DRAM Timing Selectable (SPD) CAS Latency Time Options are: Auto (default), 3~7. tRCD Options are: Auto (default), 1~15. tRP Options are: Auto (default), 1~15. tRAS Options are: Auto (default), 1~63. tRRD Options are: Auto (default), 1~15. tWTR Options are: Auto (default), 1~31. tWR Options are: Auto (default), 1~31. tRFC Options are: Auto (default), 1~255. tRTP Options are: Auto (default), 1~15. Command Rate(CMD) Options are: Auto (default), 1~3. DRAM Voltage The default is Auto. DRAM Termination The default is Auto. Channel A Reference The default is Auto. Channel B Reference The default is Auto. Thank you for your support Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted November 25, 2008 Corsair Employee Share Posted November 25, 2008 The tested settings can be found int he link in my signature just load setup defaults and set the tested settings and Voltage manually and any setting not listed should eb set to BIOS default or Auto.

inanitas Posted November 25, 2008 Author Share Posted November 25, 2008 I found it, thanks. There are still a few questions which come to my mind. 1. Why I spent money for 1066MHz memory and now need to set my clock back to 800MHz? 2. What is my RAM/computer performance impact when I overclock these modules back to 800MHz? 3. How I can distinguish that I have Version 1.x or version 2.x? 4. Can I overclock these modules exciding 1066Mhz and also get stable performance? Thanks for your help Link to comment Share on other sites More sharing options...

Thanks for your help Keep in mind that you entered a thread for an AMD system so the settings given for the person that started the thread do not apply to your system at all. You should be able to enter your BIOS and set the memory speed to run at 1066 on the MOBO you have. You will need to OC your CPU FSB to do this.

inanitas Posted November 26, 2008 Author Share Posted November 26, 2008 The thread was related to 1066Mhz memory speed and ATI Catalyst Drivers, which could work unstable under 3D games. Based on information form RAM GUY I need to overclock back my memory to 800Mhz. I did it yesterday and tested those setting under two 3Dgames, both worked stable and I did not see any problems with ATI Catalyst Driver. Previously I had similar problems like jbaines72. But still I have concern related to almost 300Mhz (memory speed) loss. Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 26, 2008 Share Posted November 26, 2008 There should be an 8.11 driver out although I am not certain if it is still a beta or not. Stability is good of course but the choice of video driver should not have any effect at all on what speed you can run your memory. That is dependent upon the hardware, specifically the memory controller and the memory. Current AMD CPUs, and especially the quad cores are VERY unstable at 1066 whereas Intel P45s are very stable at 1066 assuming the other components are up to the OC. That is why I pointed out that the given settings would not apply to your hardware, regardless of what video driver you use. Link to comment Share on other sites More sharing options...
inanitas Posted November 26, 2008 Author Share Posted November 26, 2008 I was curious as to why my video card drivers crash when I set my system memory to DDR2 1066. If I leave my memory settings in the BIOS set to auto (which makes them run at SPD settings of DDR2 800), everything runs fine. This only seems to happen when I play Call of Duty 4. If I set my memory to DDR2 1066, my computer boots, is stable, and everything works (such as web browsing, office software, etc.), but if I try and play the game, the catalyst drivers crash every time after about 5 minutes or so. Again, this is only at DDR2 1066, not DDR2 800, and it only seems to be 3D games. Thanks in advance for any help. Jeff Baines Thank you for your answer. As far as drivers are concerned, I have the newest ones, BIOS also. This thread is very interesting for me since I saw similar problems with my computer (quoted above). I was searching for solution and 800Mhz setting for RAM solved my stability issues so far. Previously I experienced game and catalyst drivers crash during play. Problem occurred regardless of video driver version (as you mentioned). From my point of view it looks that there could be some kind of conflict between Radeon 4850 and Corsair memory. Now I would like to find root cause of that situation. Maybe I should simultaneously OC my graphic card; CPU and memory to the same frequency - do not know the answer so far, probably also do not understand all interactions between hardware I got. I would expect that my RAM should operate on rated settings and not causing stability problems. Until now it works stable at 800Mhz. I am wondering if you could suggest me some solution which I could check/test. Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 26, 2008 Share Posted November 26, 2008 I split your thread off from the other thread. There is no conflict with ATI cards and our memory and, the settings and advice in the other thread do not in any way apply to an Intel based MOBO. So far, I have not seen you list any of your BIOS settings. Can you list ALL of your BIOS settings you have made for RAM, CPU, and voltages?

OldGeezer Posted November 30, 2008 Share Posted November 30, 2008 Your DRAM voltage is set for 1.8 volts. Set it to 2.1 ... or whatever your memory calls for. Set everything else, memorywise, back to auto. Link to comment Share on other sites More sharing options...
inanitas Posted December 1, 2008 Author Share Posted December 1, 2008 Thanks for advice, but I have already checked it. When I set my memory frequency to 1066Mhz (Auto mode) and my Ram voltage 2.1V it is unstable also. When my Ram frequency is set to 800 Mhz then no matter which voltage I set between 1.8 and 2.1 - the system is stable. So probably issue lies elsewhere.

Yellowbeard Posted December 1, 2008 Share Posted December 1, 2008 Just for testing, drop your CPU multiplier to 7 or 8 and see if you can then run the memory at 1066. Link to comment Share on other sites More sharing options...
inanitas Posted December 1, 2008 Author Share Posted December 1, 2008 I've done it. CPU dropped to 7x and memory increased to 1066 Mhz. Same problem as previous - stable during office operation, unstabe in 3D games. Link to comment Share on other sites More sharing options...
DerekT Posted December 1, 2008 Share Posted December 1, 2008 Please follow these instructions exactly. Download Memtest86+ V2.01 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from Here . Shut the system down. Remove the second stick of DRAM and leave only the first one in slot 1. Restart the system and enter your BIOS. Load Setup Defaults. Save Setup Defaults. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before. Enter these values: MB Intelligent Tweaker(M.I.T.)

OldGeezer Posted December 4, 2008 Share Posted December 4, 2008 You don't, per chance, have a way of booting this system into Vista32, do you? I don't get warm fuzzies when I run 32 bit applications under Vista64. I've found some of them to be a bit flaky. Link to comment Share on other sites More sharing options...
inanitas Posted December 4, 2008 Author Share Posted December 4, 2008 I think I do not understand your answer. I have only Vista64 and sometimes run 3D 32bit games which crushes when my memory frequency is set to 1066Mhz. I am wondering how your M.I.T looks like and what setting you use.

This is good that there are more people with similar problems and configuration :roll:, maybe we can resolve the issue. From may experinced setting RAM frequency back to 800Mhz improved stability. With 800Mhz I can play for hours with no error, crushes and Catalyst driver problems. But there is still concern related to 1066Mhz speed and I am going to run full test procedure soon.

Why should I underclock my cpu? Do I have to if I want to underclock my memory or? And where to I change the CPU multiplier? What setting in bios ir that? I'm kind of new to this so please explain.
