TWIN2X2048-8500C5D Compatibility Question

Recommended Posts

my problem is compatability issues with ram and the motherboard. with this ram inside the pc doesnt boot at all displaying the c1 error on mobo, a very annoying continuous beep and then having to hold in power to turn off system..i have tried switching the ram around and just using one stick, no luck :/ i have also tried changing many settings in bios eg. voltages, timings for the ram and then reinserting the dominator to see if boot is an option has made a difference...no luck so far! has anyone got a solution for me to fix this problem or is it better to change ram? ive contacted xfx for a qvl but no reply to ticket as yet so still completely stuck..thanks in advance all help appreciated.

(Ram that does enable comp to boot is just some lame samsung 667MHz 1gb stick that was in a dell)

can you reset/upgrade the BIOS? that would be the first thing i would try.

P05 is the latest IIRC.

plus your board may require certain slots for placement of ram.

please post back after you try a BIOS reset and check the manual for slots to use.

 

i was eyeing up that board myself so im very interested in your results.

thanx.

Do a hard reset of your system.

 

  1. Shut the system down
  2. Remove the power cord
  3. Remove the CMOS Battery
  4. Set the CMOS_CLR Jumper to On
  5. Press the power button for 10 seconds
  6. Let sit for 10 minutes
  7. Set the CMOS_CLR Jumper to Off
  8. Insert the CMOS Battery
  9. Insert the Power Cord
  10. Restart the system
  11. Enter the BIOS
  12. Load Default Settings
  13. Save Default Settings and Exit
  14. Restart the System and enter the BIOS

Insert these values:

[indent][i][b] Download CPU-z from--->[url="http://www.cpuid.com/download/cpuz_147.zip"][color="DarkRed"]Here[/color] [/url].[/indent]
[/i][/b]

Enter your BIOS and set to these values:

[b]Advanced BIOS Features[/b]

[b]System Clocks[/b]

CPU Freq. MHz = 2400
CPU Muliplier = 9
PCIe x16, 3, MHz = 100
SPP<->MCP Ref Clock, MHz = 200

nForce SPP --> nForce MCP = 5x
nForce SPP <-- nForce MCP = 5x

CPU Spread Spectrum: Disabled 
HT Spread Spectrum: Disabled 
PCIE Spread Spectrum (MCP): Disabled
SATA Spread Spectrum: Disabled

[b]FSB & Memory Config[/b]

SLI-Ready Memory = Disable
FSB -  Memory Clock Mode = Linked
FSB (QDR), MHz = 1066Mhz
MEM (DDR), MHz = 1066Mhz

[b]Memory Timing Section[/b]

Memory Timing Section = Expert
tCL = 5
tRCD =  5
tRP = 5
tRAS = 15
Command Per Clock = 2T

[b]Advanced Memory Settings[/b]

tRRD = Auto
tRC = Auto
tWR = Auto
tREF = Auto

[b]CPU Configuration[/b]

Limit CPUID MaxVal = Disabled
Intel Speedstep = Disabled
CPU Thermal Control = Enabled
C1E Enhanced Halt State = Disabled
Execute Disabled Bit = Enabled
Virtualization Technology = Enabled

[b]System Voltages[/b]

CPU Core = Auto
CPU FSB = Auto 	
nForce MCP = 1.60
DRAM Voltage = 2.1v	
HT nForce SPP <-> MCP = Auto

 

After setting to these values, save them and shut down. Insert a single stick of the 8500 into the first slot (Closest to the CPU) and restart. Boot to the Memtest ISO. Allow for two full passes and if stable, shut the system down. Remove the stick of DRAM and insert it into the third slot. Restart and Memtest. Finally, shut the system down and insert a stick in slot one and slot three. Restart and run memtest. If you pass, enter Windows and post a screenshot of CPU-z's CPU, Memory and SPD tabs.

ok a reply to the both of you, im not actually sure how to flash/update the bios on this new mobo it says u can do it via nvidia control panel on windows but that branch is not available for some reason :/ i cannot seem to find where abouts to go on the bios to do this either as i do have the bios iso available but the xfx website has no instructions nor does the manual on how to update the bios other than NCP which as i said doesnt display the option to. secondly out of all the things ive been told to do by DerekT one instruction i am not to sure on how to carry out and that is (Set the CMOS_CLR Jumper to On) once i know how this is done i will also try you suggestion as i am desperate to get this working!!

 

Thanks for the replies

Followed all your steps, many thanks..Got as far as testing in slot 1 and 3 and worked fine with the one stick then when the other was added it wouldnt boot, i tried this stick alone and the system wouldnt boot with it in any of the slots...a duffed ram? should i return it if so how is this done..

 

Thanks Luke

Images show ram working at low speed also..

I would either return the DRAM to the retail outlet or an RMA to Corsair. The retail outlet is faster but they have a time limit after which Corsair will handle all RMA requests.

 

Yes, it would seem you have a bad stick. This is the weekend and Corsair staff are not online until Monday.
