What cooler do you have on your CPU?

 

For your research:

Download Memtest86+ V2.01 from--->

Download CPU-z from

Shut the system down. Insert a stick in Slot 2 and a stick in Slot 4. Restart, enter BIOS, load defaults, save defaults and enter these values:

 

 

Extreme Tweaker

CPU Level Up = Disabled
Memory Level Up = Disabled 

AI Overclock Tuner = Manual
CPU Multiplier = 9
FSB - Memory Clock Mode = Unlinked
FSB (QDR) = 1600 (400)
MEM (DDR) = 2000 (1000)
LDT Frequency = 5X
PCIE BUS, Slot 1 & 2, Mhz = 100
PCIE BUS, Slot 3, Mhz = 100
SPP <--> Ref Clock, Mhz = 200

Memory Timing Section

tCL (CAS Latency) = 9
tRCD = 9
tRP = 9
tRAS = 24
Command Per Clock = 2T

Advanced Memory Settings

tRRD = Auto
tRC = Auto
tWR = Auto
tWTR = Auto
tFAW = Auto
tREF = Auto

Over Voltage = All Set to Auto

CPU Configuration

CPU Internal Thermal Control = Auto
Lmit CPUID MaxVal = Disabled
Execute Disable Bit = Enabled
Virtualization Technology = Enabled
Enhanced Intel Speedstep(tm) Tech = Disabled

CPU Core 2 = Enabled
CPU Core 3 = Enabled
CPU Core 4 = Enabled

[b]System Voltages[/b]

CPU Core = Auto
CPU FSB = Auto 
Memory = 1.90v
nForce SPP = Auto	
nForce MCP = 1.55	
HT nForce SPP <-> MCP = Auto

 

Run Memtest for two full passes. When assured of stable DRAM, then enter Windows and run CPU-z. Please post screenshots of the CPU-z CPU, Memory and SPD tabs.

These boards are quirky. Often you have to RMA until you get one that works correctly with such high end DRAM.

 

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:

You mean rma my 2000mhz ram for 1800mhz ram? or underclock 2000mhz ram?.

 

Not RMA as the DRAM is not bad. The issue is that unless you run with a 500Mhz FSB, you will have to tweak like crazy (and Intel high end boards are the only ones with the BIOS settings for such tweaking). Far simpler to either run your 450Mhz FSB with 1800Mhz on the DRAM, or lower the multiplier and set to 500Mhz (If that board will do 500MHz FSB). I'm running a Maximus Extreme on the test bench right now. Xeon 3110 (E8400) with 400FSB makes an easy 1600Mhz stable. 450FSB makes an easy 1800Mhz and 500Mhz is stable on 2000Mhz.

 

Why not test with 450 and 1800Mhz with 8-8-8-24 and 1.9v.

 

Download Everest Trial Version from here -->

Install Everest and right click on the (i) icon in the system tray. Choose Tools --> Cache and Memory Benchmark. Run the Benchmark and post the finished screenshot of 1800Mhz with 8-8-8-24 and test both 1T and 2T.

Well done, I thought the 450FSB would get you going on the right track since it sounded like you knew what you were doing. :):

do you think it be better set as linked and synch or leave it unlinked both,??

i was thinking that 2t is more stable and 1t is more unstable but faster.

I do not like automatic settings for the main DRAM. I like to set manually. Yes, with DDR2 and Intel, the 2t cycle is more stable than 1t and 2t engages on a two cycle (t) transfer. Contrary to popular belief, the Command rate or Command Per Clock rate is NOT a memory timing, it is a memory controller transfer characteristic.

 

The Command Per Clock sets the Command Rate for the memory controller. At 1T, the controller can issue commands on every clock cycle, if set to 2T the controller can only issue commands only on every other bus cycle. Don't be certain that you can not effect a 1T Command rate though. Testing is the only way to be certain.

Well Thank you a lot now i have to test if its a stable overclock. and try to get the best i can out of it.790i ultra is very picking board doesnt like to be mest around.but hey thats why you build a pc to have stress :biggrin:

I have more fun with building a system and tweaking it to get the best stable performance than I ever have with using it. Once it's all done up, it's time to move on. :D:

can any one help me?

 

You need to do this work yourself. You don't even say what voltages, what overclock, etc. It's not as though you don't know what you are doing. I gave you a link to check and that site has others with your board and they can give you better help with an overclock of the system.
