Spetter Posted August 25, 2008 Share Posted August 25, 2008 Manual settings: Dram Timing Control: Manual CAS Latency: 7 RAS to CAS Delay: 7 RASS PRE time: 7 RAS to RAS Delay 7 RAS ACT Time: 20 Everything else in Ram configuration: auto PCIE Frequency: 100 Voltage: DRAM Voltage: 1.90856 Everything else in voltage: Auto CPU Spread Spectrum: Disabled PCIE Spread Spectrum: Disabled Everything I did not mention is set to: Auto At the moment I am runing: FSB Frequency: 333 with CPU Ratio setting: 10.0 FSB Stra to North Bridge: 333MHz DRAM Command Rate: 2N Those configuration will give me a option DDR3-1333MHz in DRAM Frequency. And CPU speed are detected as 3.33GHz (the orginal speed, but Ram is FSB 333 1333mhz and not FSB 400 1600Mhz And this configuration is stable in Windows I cannot Find any divider option in bios (CPU / ram) so I cnanot set cpu Ram at 5:4 ratio (333 FSB cpu, 400 fsb RAM) So, is there possible to set CPU at FSB 333 with 1333Mhz and RAM at FSB 400 with 1600Mhz ? Or must I overclock ? I have tryied FSB frequency at 400 and FSB Strap to North Bridge at 333Mhz with every voltage set to auto exept DRAM Voltage. DRAM Frequency gets detected at DDR3-1601Mhz CPU gets detected at 4.02Ghz That configuration gets unstable and I have tryied FSB frequency at 333 and FSB Strap to North Bridge at 400Mhz with every voltage set to auto exept DRAM Voltage. DRAM Frequency gets detected at DDR3-1332Mhz CPU gets detected at 3.33Ghz That configuration is wrong then since RAM detected at DDR3-1332Mhz and not 1600 When I try the X.M.P option in bios (Ai Overclock Tuner option) (grayed out): Profile information: 1600MHz-7-7.7-20-2N-1.90V CPU Ratio Setting: 10.0 FSB Strap to North Bridge: 333MHz DRAM Command Rate: 2N DRAM Timing Control: Manual with setting 7-7-20-7 CPU Frequency gets detected at: 4.02 GHz FSB speed gets detected at: 1608Mhz With the XMP option and a CPU Ratio setting at: 8.0 - CPU get detected as 3.21GHz that is still wrong regarding the CPU. (bios detects it as 3.21 meanwhile Windows Wista 64 bit detect it as 4.00GHz) Or is this my only option if stable ? Underclocking cpu to get a fsb 1600 for the RAM ? Any suggestion ? Is my only option to overclock something ? And what voltage in ant option is prefered ? What are prefered to change in Bios to get the most optimal settings ? Or should I run both FSB and North Bridge to 333. And wait until maybe I get a FSB 400 cpu (expensive) ? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 26, 2008 Corsair Employees Share Posted August 26, 2008 You CPU would have to over clock to 1600 FSB to run the memory at DDR1600. Link to comment Share on other sites More sharing options...

Spetter Posted August 26, 2008 Author Share Posted August 26, 2008 Ok. So there is not possible to run cpu and ram at different (1333 FSB 333 cpu / 1600 FSB 400 ram) FSB speed ? What about this ? With the XMP option and a CPU Ratio setting at: 8.0 - CPU get detected as 3.21GHz that is still wrong regarding the CPU (not 3.33). (bios detects it as 3.21 meanwhile Windows Wista 64 bit detect it as 4.00GHz) Or is this my only option if stable ? Underclocking cpu to get a fsb 1600 for the RAM ? This is not Wise ? The best thing is to overclock cpu to FSB 400 to get a FSB speed 400 for the Ram ? If so. Could you suggest the voltage settings in bios ? Or is it easier if I post the options in bios for you to suggest ? Or wait until IF I get a CPU than runs FSB 400 at default speed (If I decied to go for one) Link to comment Share on other sites More sharing options...

Braulio Posted August 26, 2008 Share Posted August 26, 2008 I am thinking of buying this same memory for my Rampage Extreme. We would greatly appreciate that post the results of stability when you have oced the cpu to 400 FSB and found that the memory runs to 1600, correctly. Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 26, 2008 Corsair Employees Share Posted August 26, 2008 Spetter that is correct you would have to run your CPU at 1600 FSB on and Intel Chipset MB. You listed you had a E8600 CPU and if so it should be no problem, but you may have to run the CPU Multiplier a bit lower. Link to comment Share on other sites More sharing options...
Braulio Posted August 26, 2008 Share Posted August 26, 2008 It´s very difficult to find compatible DRAM for this Mobo ATM (mostly 2x2GB kit), so if anyone can confirm the TWIN3X4096-1600C7DHX(IN) is good for this board would be a blessing for all its buyers Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 26, 2008 Corsair Employees Share Posted August 26, 2008 Yes they would be a great choice but you will need to be running at 1600 FSB on the CPU to run the memory at DD1600 Link to comment Share on other sites More sharing options...
Braulio Posted August 27, 2008 Share Posted August 27, 2008 @Spetter: What happens? Still has not achieved stability at 400 FSB / 1600 Dram? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 Can you tell me the make and model of MB you have along with the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 Ok well I am sorry but I do not make assumptions and if its not clear I will ask, and I did??? And what about the rest of the question???? Link to comment Share on other sites More sharing options...
Braulio Posted August 27, 2008 Share Posted August 27, 2008 I´m sorry...It must be my poor english. I thought I had said this before quite clear. Im a Rampage Extreme owner with too much dram problems. My actual set (1800 from another brand) dont works (even in 1600). My first goal is run 1600 dram/400 FSB in my Q9550 with default timings, simply. Im in this thread waiting for the spetter´s stability tests for ordered or not a TWIN3X4096-1600C7DHX kit. Any recommendation would be deeply grateful. Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 I am sorry it is still not clear to me what you are trying to set in your BIOS. However as a rule you have to run the CPU at 1600 FSB in order to run the memory at DDR1600. And that CPU runs at 1333FSB By Default so it would have to over clock to run the memory at their tested settings. Link to comment Share on other sites More sharing options...
Braulio Posted August 27, 2008 Share Posted August 27, 2008 My initial goal: Fsb: 400 Sdram Frequency: 1600 Timings (primary): memory default (7-7-7-20/18) Vdram: default for the timings above 10h+ stable in Intelburntest. 24h+ stable in Prime95 Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 O.K. if its stable for 10 Hours in Prime95 then the modules are fine, if that was your Goal and it was not achieved then I would try and lower the CPU Multiplier and test them again. In addition, running the system for more then 30 Min to hour in either of those tests should show a failing module, if you get errors in several hours into any test like that would suggest some other problem most likely a thermal or Voltage issue with the MB PSU or CPU.

Braulio Posted August 27, 2008 Share Posted August 27, 2008 Yes, that was my Goal and it was not achieved so far. He made every kind of test to conclude that it is a pure issue of dram compatibility with this picky, picky picky board. For all this, i want to buy Corsair.

Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 I would suggest TWIN3X4096-1600C7DHX for that MB and make sure that you have the latest BIOS version installed as well. Link to comment Share on other sites More sharing options...
Braulio Posted August 27, 2008 Share Posted August 27, 2008 Exactly, these are the modules that want to buy. But I feel much safer if spetter return to this thread to tell us how they are working on their Rampage Extreme. There is only published some test of this board with Dominator, and we know that the xms cl9 kit runs well in this board too, but none test so far with xms cl7 modules. Only spetter can say so far something to the community. And there are many people waiting to know this. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2008 Corsair Employees Share Posted August 27, 2008 NP I am sure there are several people watching this thread, and I have asked that we try to get this on the schedule to test but it will not be listed in Test reports. But I will let you all know if we see any problems. Link to comment Share on other sites More sharing options...
Braulio Posted August 27, 2008 Share Posted August 27, 2008 THANKS, Ram Guy, thanks...It´s very painful to have this board only @ 333 fsb by dram issues. :[pouts: Link to comment Share on other sites More sharing options...
Spetter Posted August 27, 2008 Author Share Posted August 27, 2008 I do not have time to test Motherboard and Ram yet. Will try to do some overcloking in the weekend few days from now. At the moment I am running CPU and Ram at FSB 333 sync mode. I have only changed the CPU fan. I hope that is enough. Or do anyone suggest to switch more from the original design ? (meaning fan at SB and NB etc) Link to comment Share on other sites More sharing options...
Spetter Posted August 27, 2008 Author Share Posted August 27, 2008 Can you tell me the make and model of MB you have along with the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? I could run Everst and copy/paste settings from Everst then maybe you could suggest volt settings etc in bios. Will copy/paste settings around Friday my timezone. I have too much to do before that.
