John5788 Posted March 28, 2009 Share Posted March 28, 2009 I bought the EVGA 780i SLI FTW board along with the Corsair Dominator ram CM2X1024-6400C4D back in december and left the default bios settings until a few weeks ago when the system would not boot and threw a C1 error code. I looked online for the C1 code and found out that I needed to set the right settings in the BIOS. After changing the default settings from 5-5-5-18 @ 1.9V to 4-4-4-12 @ 2.1V, the system booted up perfectly and I ran it for about a month straight without powering it off. Today I powered it off, and when I powered it back on later, the system gave me another C1 code. I took 1 DIMM out and the system booted up fine. I swapped the DIMM with the other one, and it would not boot, but it did not give me a C1 or beep code. It just never posts and the diagnostic code was 0D which tells me nothing. So right now I am running on 1 DIMM, 1024MB, the other DIMM is sitting on my desk and wont power the machine on (is it dead?) I'm not sure what to do anymore, are there more settings that are incorrectly set which I should take a look at? Link to comment Share on other sites More sharing options...
DerekT Posted March 28, 2009 Share Posted March 28, 2009 Download Memtest86+ V2.11 from--->Here Download CPU-z from--->Here . Insert a single stick in the Slot 1 (Closest to the CPU) and enter your BIOS. Load Setup Defaults. Save Setup Defaults and set to these values:Advanced BIOS Features System Clocks CPU Freq. MHz = 2.40Ghz CPU Muliplier = 9 PCIe x16, MHz = 100 SPP<->MCP Ref Clock, MHz = 200 nForce SPP --> nForce MCP = 5x nForce SPP <-- nForce MCP = 5x FSB & Memory Config SLI-Ready Memory = Disable FSB - Memory Clock Mode = unLinked FSB (QDR), MHz = 1066Mhz MEM (DDR), MHz = 800Mhz Memory Timing Section Memory Timing Section = Expert tCL = 5 tRCD = 5 tRP = 5 tRAS = 15 Command Per Clock = 2T Advanced Memory Settings tRRD = Auto tRC = Auto tWR = Auto tREF = Auto CPU Configuration Limit CPUID MaxVal = Disabled Intel Speedstep = Disabled CPU Thermal Control = Enabled C1E Enhanced Halt State = Disabled Execute Disabled Bit = Enabled Virtualization Technology = Enabled System Voltages CPU Core = Auto Memory Voltage = 1.9v CPU FSB = Auto nForce MCP = 1.30v HT nForce SPP <-> MCP = AutoAfter setting to these values, save them and boot to the Memtest version 2.11 ISO. Allow for two full passes. Remove that stick and insert the second one into slot 4 and retest. Finally, insert a stick in slot 1 and slot 4 and retest and if stable, enter Windows. Run CPU-z. Post the CPU, SPD and Memory tabs. Results? Link to comment Share on other sites More sharing options...
John5788 Posted March 28, 2009 Author Share Posted March 28, 2009 ok I just tried those settings and the system won't boot with the other DIMM still. should we conclude that the DIMM is bad? Link to comment Share on other sites More sharing options...
DerekT Posted March 28, 2009 Share Posted March 28, 2009 Did you test in the same slot that the working one was in? If so, yes, it would seem that you need to process and RMA. If not, then test them both singly in the same slot. ok I just tried those settings and the system won't boot with the other DIMM still. should we conclude that the DIMM is bad?

John5788 Posted March 29, 2009 Author Share Posted March 29, 2009 yes I tested them both in the same slot as the working one (the first one, closest to CPU) and the other DIMM does not boot. it gives me a 0D error instead of a C1 though. how does the RMA process work? would I have to send both DIMMs in to be replaced? or would they send me the new DIMMs first and I ship the bad pair back? or would corsair just send me one dimm for the bad one? can I even RMA if i redeemed the rebate on it? I bought the deal on newegg.com and it had a rebate attached to it. Link to comment Share on other sites More sharing options...
DerekT Posted March 29, 2009 Share Posted March 29, 2009 Yes, you can RMA even if you have had a rebate. You send the memory in and they send new memory back. They need both because they have to send you a matched pair back. yes I tested them both in the same slot as the working one (the first one, closest to CPU) and the other DIMM does not boot. it gives me a 0D error instead of a C1 though. how does the RMA process work? would I have to send both DIMMs in to be replaced? or would they send me the new DIMMs first and I ship the bad pair back? or would corsair just send me one dimm for the bad one? can I even RMA if i redeemed the rebate on it?

John5788 Posted March 29, 2009 Author Share Posted March 29, 2009 how do people normally RMA memory that is needed to run their computers? I don't have any spare DIMMs laying around to run my computer if i send this pair in. Link to comment Share on other sites More sharing options...
