Windows 7: 1066 RAM on 1.8 V Motherboard?

1066 RAM on 1.8 V Motherboard?

I have an Intel DP35DP motherboard (and Q6600 CPU) that requires 1.8V RAM. It is capable of using 1066 memory but all the 1066 memory I find is 2.2 Volt. There is nothing that I can find in the BIOS about changing voltage as suggested by other sites.

The BIOS states "System Bus Speed 1066Mhz" and "System Memory Speed 800Mhz" (I have 800 Mhz memory installed).

Although I probably wouldn't really see a difference between 800 and 1066 speed, I'm curious if the 2.2 volt memory would work (and work properly)?

I just went to the corsair site and used the motherboard search feature and came up with the recommended memory available for your motherboard - its all 1.8volts :
Intel DP35DP Memory Upgrades - Guaranteed Compatible Memory for your Intel DP35DP from Corsair

I then did a search for my board Asus P5E and found it supported the 2.2v 1066 memory so I would say no you cant use the 2.2v 1066 memory with your board without risk of hardware failure.

Still not 100% happy I did a bing search, and ended up selecting the official intel site which also specifies 1.8 volt memory :

Bing Search below if you want to do some further searching :

Thanks for the response. I know it's 1.8V but just wanted to know if anyone either has installed 2.2 V memory in a system that specifies 1.8V or knew that 2.2 would work.

Most people who buy 2.0-2.2V memory just plop it in and run it. Almost all boards will run DDR2 at 1.8 so it will work fine. That voltage is for enthusiasts who want every bit of performance out of the memory. You might not have the option to change voltage. If you do.....change it to the specified voltage on the sticker. If you don't, it will run fine if you don't overclock it. You could always run a stress test like memtest or Prime95 or Orthos and see if you get any errors.

Thanks, that is what I wanted to know. I don't have any 1066 RAM but if I get a wild hair and decide to upgrade to 1066 I'll just buy one ram stick to see if it works before I completely switch to 1066.

Well, best of luck. It will work fine.

You can always get lower voltage RAM if your board does not support voltage changes. It's out there I'm sure.

@$$$$ seems to me if your not certain you can increase the voltage you might as well buy cheaper 800 mhz rather than buying 1066 mhz, which maybe be reduced to 800 mhz - from what I can gather it would be worth doing some more research, as intel boards have been known to have restrictions.

I just did some searching and found crucial support a 1.8 volt 1067 mhz (pc-8500) and all the compatible modules are 1.8 volt so it seems either corsair didnt make any or there is some other reason - anyhow, have alook for yourself, but it does point to the fact you may not be able to use 2.2 volt ddr2 with the board.

Sorry if Im sounding negative, but i have read on forums where people are buying memory, and it wont run at the speeds they say it will - i think Nat would know more about it than me, as he is in the business of buiding PC's.

Hmm, Crucial not listing 1066Mhz memory for the DP35DP motherboard is what started it all. Same way, I couldn't find any at CompUSA or newegg. I have 800Mhz installed, since I couldn't find any 1.8V 1066 memory when I was looking. As I stated originally, I don't know if 1066 would even make a difference.
