The 1066 is your memory buss freq, that is the default for the processor/MB you have, it will only go over that if you specifically overclock your system. People buy 1600 mhz ram in order to be able to overclock but you don't have to and may not even want to run it that fast (excessive heat, premature ram death and system instability may result). It's pretty rare to get a stable memory buss speed of 1600.

On the other hand your CPU speed will go up and down from about 1600 (just a coincidence) to 2800 to 3400Mhz depending on the CPU model. (Again without overclocking)

Most ram sold today is 1600 or even higher, but that doesn't mean that you can even attain those speeds, just think of it as generous overhead. Ram speed in itself really doesn't get you much anyway. Better overclocking often results in OCing the CPU but keeping the ram set to a lower speed for improved stability and the difference in anything other than a pure memory benchmark is virtually nothing with the speed at 1066 or 1600.
Actually you can run @1600MHz with the click of a BIOS setting without even having to overclock the CPU just by enabling XMP.

So, if the RAM is 1600 and the memory and motherboard support XMP, choosing the XMP mode WILL run the memory at 1600. Or.... you can set it manually and still not touch settings that overclock the CPU.

Yes, even though my system IS overclocked, it's not because of memory! If I was running at stock CPU speeds, I could still run the memory at 1600MHz

My two cents.

i tried this just now, and my rig was making a high pitched noise, and woulndt boot...

my BIOS should be able to handle it, but somehow its getting thevoltage wrong (my guess), and i`m not qualified to be messing around with voltage`s and stuff, not for the money i put in this rig.

so i guess i`m leaving it this way...

Actually your memory is running @ 1079.4 since the memory is dual channel - 539.7 x 2 = 1079.4

See these posts....

- my ram (1600 mhz) is showing as 1066mhz

- win7 64bit only recognizing 6gig of my 8gig of ram

Also have a look at your CPU-Z memory tab. Here's mine

Hmm, I haven't tried looking at that, I'm running at 1333 myself. THough in the past I've generally found that maxing the ram speed isn;t all it's cracked up to be, the temp on the modules tends to skyrocket for virtually no gain in app benchmarks so I personally just let it slide with the BIOSes safe and sane settings WRT memory... But It might be interesting to give it shot, I've to temp probes on my modules already

I've actually never ever had high temps with my memory because I don't push them byond their specs!

I use Corsair and they guarantee their memory to run at the specs they set. This includes no excessive heat.

Now, if you push beyond limits.... well

Anyway the modules I have also feature an XMP profile that automatically sets volts, timings and speed. Of course the motherboard's BIOS also has to support XMP as well.

However, I like to set my memory manually as I find the XMP settings on my board tends to slighty overvolt certain settings. This ensures I have the memory running at it's optimum speed without overvolting.

Also, as a side note.... some memory will give errors if not set correctly. Example, most X58 boards will set the memory voltage to 1.5volts instead of the recommended 1.6volt some memory need.

So for example, you buy "performance" memory that's rated at 1.6volts, but the board sets them at 1.5, the memory "may" produce errors unless the voltage is raised to the recommended specs.

This is why some people have "issues" with "performance" memory. This is why I always recommend people set their memory manually.

My two cents.

Unless I am wrong your cpu's integrated memory controller only supports ddr3 800/1066

It may say that, but the support is actually higher for the memory. And let's not forget, the BIOS's will determine that as well.

Intel may not "officially" support it, but the support is there. Sort of like they don't officially support overclocking..... but their i7-920's/930's are flying off the shelf with this specifically in mind

I can't find it right now, but there was some controversay about Intel's board (DX58SO) failure to support 1600MHz RAM and Intel released a BIOS supporting it.

Hello. I just bought a new set of ram (CML8GX3M2A1600C9W) because i had bsod issues with my previous set (two sets of the same memory different versions). When i set them at xmp profile1 i get bsod (error 0x124). Any ideas on how to set them up to work at 1600 without problems?
