rajka Posted November 3, 2004 Share Posted November 3, 2004 I haven't found anything about my own problem, so if any of you could help me I'll appreciate his effort. :) My hardware configuration is: CPU AMD Athlon64 3200+ Asus K8N-E Deluxe Bios 1006 Beta 008 (I also tried the 1005 stable) Sapphire ATI Radeon X800XT For the above - Settings: Bios Defaults cmx256a-3200c2 xms3202v1.2 cmx512-3200LL xms3205v1.2 Memory Slots 2&3 Settings: MemClock: 400MHz CAS Latency: 2.0 DRAM RAS TO CAS Delay: 3 CLK DRAM RAS PRECHANGE Time: 3 CLK DRAM ACTIVE TIME: 6 CLK 1T/2T Timing: Auto DDRRAM Voltage: 2.7V I've read some of the above values in other threads in this forum. In short my problem is about memory clock. The two corsair modules go at 333MHz. If I use only one module at a time it goes at 400MHz, but in pair they slow down to 333MHz. I've also tried with higher timings, bios default timings but nothing to do. It seems they can't work at 400 in pair. The funny side of the story is that before I had an Abit AN7 and they worked fine with lower timings than the above (2-2-2-6) at 400MHz. Any ideas? Do I have to wait for a new BIOS? Thanks in advance. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 3, 2004 Corsair Employees Share Posted November 3, 2004 You really need to use modules that are exactly matched with this platform, sorry but many of the newer MB's will be like this. You will have to set the memory frequency and timings manually but this platform still seems to try and read the SPD for the Clock frequency and because the 2 modules have different timings set at different speeds the bios goes for the closest match Cass 2 at DDR333.

Osborn Posted August 16, 2005 Share Posted August 16, 2005 I have the same problem. I have Asus K8N-E Deluxe, Corsair VS512MB400 and AMD Athlon 64 3000+. Informations from the SPD read with CPU-Z: http://people.freenet.de/Osborn2/cpu-z-spd.JPG I set this SPD Setting in BIOS, but this comes out http://people.freenet.de/Osborn2/cpu-z-memory.JPG I try another Voltages, 1T/Auto and other settings, but nothing helps me. I have BIOS 1010. If i try BIOS 1006, then is the Frequency 200 MHz (correct), but i dont understand, why not by BIOS 1010. What ist the best slot combination and voltage? 1-3 @ 2,7 V? Why? Sorry for my english. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 16, 2005 Corsair Employees Share Posted August 16, 2005 Well no Osborn; it’s not the same issue exactly. Please install the modules in slots 1-3 or 2-3 and then see if the modules will post at DDR400 and I would set the dim voltage to 2.7 Volts as well. And if you install more than 2 modules you will need to run the memory at DDR333. If not please test the modules one at a time to make sure they are both the same SPD.

Osborn Posted August 16, 2005 Share Posted August 16, 2005 I test this combinations Slot1 - Slot2 - Slot3 - MemoryClock x1 - 00 - 00 - 200 00 - x2 - 00 - 200 00 - 00 - x2 - 200 x1 - x2 - 00 - 166 x1 - 00 - x2 - 166 00 - x1 - x2 - 166 x2 - x1 - 00 - 166 x1 = DIMM1 x2 = DIMM2 I set the Voltage to 2.5, 2.6, 2.7 and 2.8 but ever 166 MHz if i use two DIMMs. The SPD of both DIMMs are equal.

Corsair Employees RAM GUY Posted August 16, 2005 Corsair Employees Share Posted August 16, 2005 But what are th e timings that are getting set for each module? Are they both getting set to Cas 2.5-3-3-8 when set to BY SPD? And what is the MB Bios version you have on the MB? Link to comment Share on other sites More sharing options...
Osborn Posted August 16, 2005 Share Posted August 16, 2005 I dont test this. Moment please. Link to comment Share on other sites More sharing options...
Osborn Posted August 16, 2005 Share Posted August 16, 2005 Okay, i test DIMM 1 and 2 alone with BIOS Version 1010.003. Here are the two CPU-Z Reports http://people.freenet.de/Osborn2/cpuz-dimm1.htm http://people.freenet.de/Osborn2/cpuz-dimm2.htm http://people.freenet.de/Osborn2/cpuz-dimm1and2.htm I also tested with BIOS Version 1006 and then is the MemClock 200 (DDR400), but not with 1010. I found this Thread in the Asus Forum http://vip.asus.com/forum/bbs_view.aspx?board_id=1&model_name=K8N-E+Deluxe&message_id=20050709223517755&filter=5&page_size=10&elite=0&SLanguage=en-us&topic_page=5&page_cnt=11&recc=107 I think its not possible to have DDR400 with BIOS Version 1010. I think i must use older BIOS Version. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 16, 2005 Corsair Employees Share Posted August 16, 2005 The modules should be in slots 1-3 or 2-3 if you have a socket 754 MB and I would try resetting the bios and then load setup defaults and set the Dim Voltage to 2.7 Volts and see if the system will post at DDR400 with both modules. If not the fact both will run properly would suggest some other problem. But you can test them in another system to be sure. Link to comment Share on other sites More sharing options...
Osborn Posted August 16, 2005 Share Posted August 16, 2005 I do what you say, but the problem is not solved. The MemClock is at DDR333. I cant test the modules in other mainboard, but i think the modules self works correct. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 16, 2005 Corsair Employees Share Posted August 16, 2005 I am sorry but it would look as though this is a bios issue. But I have no problem replacing the modules if you want to try that. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! But I would go back to a previous bios version and see if the system will work properly. Link to comment Share on other sites More sharing options...
Osborn Posted August 16, 2005 Share Posted August 16, 2005 Yes, i try older BIOS Version. Thx for Help. Link to comment Share on other sites More sharing options...

Osborn Posted August 17, 2005 Share Posted August 17, 2005 I install BIOS Version 1008.005 and Memory is by 2,5-3-3-8-1T @ DDR400. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 17, 2005 Corsair Employees Share Posted August 17, 2005 Well if I understand what you have posted I would suspect an issue with the new bios. Sorry, but the MB maker will need to address this. Link to comment Share on other sites More sharing options...
Osborn Posted August 18, 2005 Share Posted August 18, 2005 Yes, the Corsair modules are perfect. The motherboard BIOS is the problem. Thank you. Link to comment Share on other sites More sharing options...
