I can't run Corsair Dominator 2 1066MHz stable. It only runs stable at 800MHz
with 4GB of total ram. My computer will reboot and if it doesn't reboot the performance sucks in games with alot of lag. I'm running Vista x64-bit
and have downloaded alot of new patches off Microsoft's website so I'm covered there. Any suggestion you might know of that would help me resolve this problem????? :(

If you know of more patches please post the url links...thanks! :D

what's your voltage?

What motherboard are you using. I had the 975 board and could never run it at 1066mhz. I changed to the EVGA 680i and have never had any issues, even overclocked to 1200mhz.

I believe that it states that you have to use a 680i mobo to achieve better OC'ing results.

Digital Trans, are they the 8500C5D modules? If so I have the same and mines went up a little past 1200 Mhz. I dropped it down to 800 and lowered the timings and everything seems a little more responsive anyways.

Whats the big advantage of running it at 1066 vs 800 when you can use better timings and the 1T command rate? Other than running linked and synced.

I have the same memory and am unable to run it at its rated speeds on my Intel 975 based Bad Axe 2 board. I was told by the guys at Corsair that this is not a limitation of the memory, but rather the memory control on the motherboard. Apparently running four modules puts a lot of stress on it, and as such they don't recommend running over 800DDR2 speeds with all four slots populated.

Yeah i heard about that with the Intel boards, it was also noted that the north bridge temps increased a lot with 4 DIMM's installed.

Okay, I have the Asus Striker Extreme 680i Intel Edition motherboard with bios version 1305 I even have the Corsair Airflow fan on the memory to keep it cooler. I also have taken off the side panel and front panel and the air just keeps it even more cooled and the CPU is water cooled. I went to CompUSA and exchanged the memory for a new set 4GB total. I'll post a report to see if there has been any change with the newer memory or if I'm still going to have to keep the speed down clocked. If anyone knows of a good solution...please share it!

Memory voltage is set at what Corsair recommends which is 2.20V
and the NB Core voltage is set to 1.40v Again, this what Corsair recommends.

Yes, 8500C5D modules.

Those are the exact same modules i'm using. I only have 2x1gb sticks. Have you tried just running one set at that speed. If you still have no joy, there maybe an issue with your motherboard.

I have the new replacement memory which I will be giving it a try. I hope the motherboard doesn't have an issue.

I reverted back to Asus bios version 1101 and everything is running perfect! :)

I read on the Corsair fourms that they don't use Micron D9 no more because they can't get them,and the one they are useing now for the PC8500C5 Dominators are called Qimonda and some people can not even get them to run they stated speed and overclock like sh!t.

before they were using Promos chips, eh... that sucks about the D9 chips if that is true :eek:

looks like it'll be OCZ DDR3 for me now :D

Well, I'm still getting blue screens and reboots. I've come to the fact that NVIDIA Nforce 680i JUST SUCKS!!!!! Thank god I just Ordered an Asus Maximus Formula with the X38 Intel Chipset which will arrive very soon.

I could have told you that before :rofl

have you updated to the P31 bios? My CPU temps have dropped about 7*C for some strange reason after updating the bios from P26.

It might help you with your stability issues. What voltages are you running?

EDIT: Oh wait you have the Asus, I have the eVGA, nevermind :|

If I were you I would run the memory at 800 Mhz and lower the timings. It should run stable and be quicker than having it at 1066.

I am and I'm still getting problems. This board sucks! My new Asus Maximus Formula will arrive very soon. It has to be this 680i motherboard giving me hell.

I had to swap my C5D 1066mhz for some xms2 800mhz because of the exact same problem.

At 1066mhz the ram voltage went to 2.2v and when i lowered it to 800mhz it went to 2.1v which i found more stable but at the cost of crap timings thus changing the ram for the less expensive 800mhz xms2 with better timings at that bandwith. Never had a problem since and tbh i think the problem lies within the Nvidia EPP's on the c5d.

I ordered the Asus Maximus Formula SE with the X38 Intel chipset to fix my problem. The board is to support DDR2-800 and 1066MHz memory Right out of the box. I have that damn nForce 680i Chipset. All Intel needs to do now is get NVIDIA to allow SLI branding on the future Intel chipset motherboards so everyone can be happy and the boards them selfs will have even more advanced future inabled hardware features.

Yeah it's a known issue for older boards that the memory controller is not up to scrach. the newer P35/X38 seem to be fine. But all the others have to drop speed. PC6400 has to drop to 666MHz, PC8500 has to drop to 800MHz. This only happens when all sockets are populated.
