Well I got this fancy new DDR3-1600 CL7 @ 1.9V memory and a shiny new motherboard to go with it. I have updated the BIOS to the latest listed (as was recommended by the reviews I read). My memory is rated at 1.9V but it defaults to 1.5V. If all I do is increase the memory voltage to 1.9V the computer will reboot several times and then restore the "last known stable settings".

So anyone know why the board is so unstable when all I do is increase the memory voltage?

That seems very strange. I'm also having a hard time with my Gigabyte P45 DDR3 board, but not like that. Have you tried 1 stick? Memtest? Maybe you have a bad stick. Is it 2X2GB? Maybe add a little to NB?
All DDR3 defaults to 1.5, have you tried stability tests at stock without resetting voltage?

I checked the Newegg reviews and everyone is complaining about the F3H bios and say to run the F2 bios. I am going to try that.

I tried both and found no difference. Let me know if you think it's better.

Well everything is working with the F2 BIOS. I am now running at DDR3-1333 CL7 at 3.00Ghz (333x9).

However my memory bandwidth seems poor, around 6GB/s.

At least my Windows Performance Index is back to a 5.9 (was 5.7 because of memory). But that doesn't mean much because my DDR2-800 CL5 was also 5.9!

Hey guys
I think there is a f4b from 7-2009 on web site. Its what i am running on my GA-EP45T-DS3R board. Your memory bandwidth is too low if its is read measure. should be @ high 7K with 7-7-7-24 timings.

I am no expert by any means, so I'll pose this as a question. Does having C1E enabled throttle your mem voltage as well as your cpu? If this is the case then you might just be looking at throttling.

death Im pretty sure C1E doesn't throttle you mem volts and its only active when the CPU is at idle. Shouldn't be issue.Paul try loading fail safe values then check memory settings start of 8-8-8-24 and stock Cpu settings and see if you have problems...aslo make sure you have power to the 8 pin on your board by Cpu !! Very Important !!
