tsipour Posted March 26, 2009 Share Posted March 26, 2009 Hi to everyone! I have bought a new pair of corsair memory to add to my pc. It's the TWIN3X2048-1333C9 G. It says the timings are 9-9-9-24, running at 1.6 v. The existing ram i have as indicated in my signature is a pair of Gail 1333 7-8-8-25 running at 1.7 v. How should i tweak the bios settings in order to have them both operate without problems? I haven't installed them yet. The current bios configuration is this: Robust Graphics Booster ...............: Auto CPU Clock Ratio ..........................: 9x Fine CPU Clock Ratio.....................:0.0 CPU Frequency ...........................: 3Ghz (333x9) Clock Chip Control Standard Clock Control CPU Host Clock Control..................: Disabled CPU Host Frequency (Mhz) ............: 333 Mhz PCI Express Frequency (Mhz) .........:100 C.I.A.2 .................................:Disabled Advanced Clock Control CPU Clock Drive...........................: 800mV PCI Express Clock Drive.................: 900mV CPU Clock Skew (ps)....................: 0ps MCH Clock Skew (ps)...................: 0ps DRAM Performance Control Performance Enhance...................: Standard (G)MCH Frequency Latch...............: 400 System Memory Multiplier ..............: 4.00 Memory Frequency (Mhz) ..............: 1333 DRAM Timing Selectable ................: Manual Standard Timing Control CAS Latency Time........................7 tRCD .........................................8 tRP'...........................................8 tRAS..........................................25 Advanced Timing Control tRRD...........................................5 tWTR..........................................12 tWR............................................14 tRFC...........................................65 tRTP...........................................7 Command Rate (CMD) ....................2 Channel A Static tRead Value.........................:11 tRD Phase0 Adjustment...................:Auto tRD Phase1 Adjustment...................:Auto tRD Phase2 Adjustment .................:Auto tRD Phase3 Adjustment..................:Auto Trd2rd(Different Rank)....................:Auto Twr2wr(Different Rank)...................:Auto Twr2rd(Different Rank)...................:Auto Trd2wr(Same/Diff Rank)..................:Auto Channel B Static tRead Value.........................:11 tRD Phase0 Adjustment...................:Auto tRD Phase1 Adjustment...................:Auto tRD Phase2 Adjustment .................:Auto tRD Phase3 Adjustment..................:Auto Trd2rd(Different Rank)....................:Auto Twr2wr(Different Rank)...................:Auto Twr2rd(Different Rank)...................:Auto Trd2wr(Same/Diff Rank)..................:Auto Motherboard Voltage Control CPU CPU Vcore….……….........................:1.22500V CPU Termination…..... 1.200V CPU PLL…………………....1.500V CPU Referen.…………....0.760V MCH/ICH MCH Core…………….....1.300V MCH Reference….…….0.760V MCH/DRAM Ref.…......0.750V ICH I/O……………….....1.500V DRAM Voltage ……....1.700V DRAM Termination .…0.7500V Channel A Reference :0.750V Channel B Reference :0.750V Ch.A Address VRef:0.750V Ch.B Address VRef:0.750V Any help will be very appreciated.

DerekT Posted March 27, 2009 Share Posted March 27, 2009 The only memory Corsair supports in a four DRAM slot population is their Quad kits. This does not mean two dual kits or even worse two dual kits of different versions or different manufacturers will not work together, just that you have no recourse to RMA Corsair if they do not work together. If there are problems with the Corsair DRAM modules, they are still supported via lifetime warranty, but that is for physical defects and errors in a two stick kit mode. Matched Quad sets are highly binned modules for a four slot population. The Dual sets are tested as a kit, not a Quad and warranted as a dual kit, not a Quad setup. You need to Memtest them as Kits (2 modules, not as a four DRAM slot population). If they fail as a kit or singly, then you have RMA. Keep in mind that there is no support for mixing and matching different versions of DRAM either since different version are of different fabrications and/or manufacturers. They might work, they might not work, but you have no support if they do not work. Thus you are advised to buy all the DRAM at the same time and in this way be more assured of getting the same versions. If you buy online, be sure to specify same versions of the modules. You are advised to drop the bandwidth to 1066Mhz and raise the NB Voltage +.2v. Also, you are advised to set the timings to the highest latencies of your modules which is 9-9-9-24 2T. Download Memtest86+ V2.11 from--->Here Download CPU-z from Here .Shut the system down and insert a single stick of memory into the slot 1 (Closest to the CPU) 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.)

Boot to the Memtest CD with that single stick and allow for two full passes. Shut the system down. Remove the first stick and insert it in slot two. Repeat memtest. Shut the system down. Remove the first stick and insert it into slot three and repeat memtest. Do the same for the last slot. You have now tested one stick and all four slots. Shut the system down and insert the second stick in slot one. Retest. Shut the system down and remove the second stick and insert the third stick in slot one. Repeat Memtest. Do the same with the last stick. You have now tested all four sticks in single channel mode. Now test for the Dual Channel Mode function of the memory controller. Insert a stick in slot one and three and memtest. Remove the set and insert the second set in slot two and four and memtest. Finally, insert a stick in slot one and slot three, a stick in slot two and slot four and repeat Memtest. If Stable enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs. If Stable enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs. As well, please post your report such as: Stick 1 & 2 = Corsair Stick 3 & 4 = Other Model Stick 1 - Slot 1 = No boot/Pass/Fail Memtest Stick 1 - Slot 2 = No boot/Pass/Fail Memtest Stick 1 - Slot 3 = No boot/Pass/Fail Memtest Stick 1 - Slot 4 = No boot/Pass/Fail Memtest Stick 2 - Slot 1 = No boot/Pass/Fail Memtest Stick 3 - Slot 1 = No boot/Pass/Fail Memtest Stick 4 - Slot 1 = No boot/Pass/Fail Memtest Stick 1 & 2 - Slot 1 & 3 = No boot/Pass/Fail Memtest Stick 2 & 4 = Slot 2 & 4 = No boot/Pass/Fail Memtest Results?
