RAM not running at correct speed

[Chris M]

I got the GA-X58A-UD5 (rev. 1.0) motherboard and I got 6GB of OCZ 1600MHz DDR3 RAM (product code: OCZ3G1600LV6GK) but it only runs at 1066Mhz instead of 1600Mhz.
If I try to increase that the system fails to boot. Whats going on?

I got the latest BIOS for the motherboard and everything...

Have you tried manually entering the timings as well? Might not be recognised correctly :/

The RAM voltage may need to be adjusted also, might need to be at 1.65V or so (1.65V is still safe so you can try it anyway to see if this works). This is just touching the multiplier and not the base clock right?

If it has an XMP set it in the BIOS to that if not use the manual settings and up the voltage to the recommended which if memory serves me is 1.65v. If you still have no joy try running Memtest86 on the modules one at a time.

I will try changing the voltage, but I've done that before when changing the multiplier and had no success
I will also try and manually enter the timings

I got an i7 940 and someone said to me that an i7 will only recognise upto 1066Mhz RAM. To go past that you got to OC it. This true?

Oh and my RAM isnt XMP sadly :/

Do I need to increase the multiplier? Or is there another way?
Sorry im a bit of a newbie at this

[Chris M]

I had no luck when entering the timings manually, upping the voltage and multiplier. It simply doesnt load into windows.
What I did notice though was the default timings werent what the stock speeds should be. Default should be 8-8-8-24-1t but I think they were 7-7-7-16-1T
I've tried increasing the voltage to 1.64v as there isnt a 1.65v option.

Whats next?

CPU-Z notices the timings change, but doesnt seem to notice my voltage change. It still says it runs at 1.5v...

Are you running the latest BIOS version? If not update it.
Have you tried Memtest86?

[Chris M]

Got the latest BIOS
Not tried Memtest as I dont have it installed

You can download the free program Memtest86 here:

You need to burn it to a disk and then you can boot from it. Test your memory one stick at a time if you want to be thorough.

Thanks, I'll give it a try tomorrow

Don't fuss over timings, or even volts too much (most RAM will run fine at 1.5v on UD boards even if listed as 1.65v by vendors), and latencies are not a major issue at this stage.

Take a good look over speed settings for the RAM, my guess is you have not increased things a notch, since timings/volts alone wont help matters.

I can't find BIOS screenshots right now, or  could indicate relevant pages.
