Ep45-ud3r bios 9

[ivanmoe]

Recently, I downloaded BIOS 9 for my Rev 1.1 board, and flashed it from a thumb drive. The upgrade went fine, but I have a problem.

No matter what I set the memory to in the BIOS, the board resets it 5-5-5-18, when I save and exit.

I've tried numerous combinations of settings, but it always reverts to the lower, and I assume more stable settings.

My memory is Crucial Ballistix PC6400 and the default settings are supposed to be 4-4-4-12 and 2V when running at 800mhz.

Before the BIOS update, that what I had it set to run at.

Anyone know how to fix it, short of flashing back to an older version of the fimware?

Re: Ep45-ud3r bios 9

Did you load and save optimum defaults as soon as you completed the bios flash?.
Supposed to do that immediately after any flash.Then you can change settings on the next repost.
It may still work.

Yes, I loaded the optimized defaults after the flash.

I also loaded them before the flash.

Again, what I describe above wasn't an issue before the upgrade to F9.

When set to run as PC6400 as it's intended to do by Crucial, the memory defaults back to 5-5-5-18.

The factory settings for that speed are 4-4-4-12 @ 2V.

However, I can't even set the memory to those numbers manually, as the board simply lowers them back to CAS 5 when it's restarted.

The mobo will allow me to up the voltage, however.

Does your RAM have an XMP profile in its SPD? If so you'll get an option to turn it on and off in the DRAM options section of the MIT menu.

If you still have problems, or don't have an XMP setting can you fill in the following BIOS profile exactly with your current settings (when it defaults to 5-5-5-18), replace the values in the [ ] with your own, this is just a sample template for my own stock settings. Include your CPU specs, and a link to your RAM direct from the manufacturers site if possible. Without CPU and RAM info, it's difficult to be able to recomment good BIOS values for things like MCH Frequency Latch etc, as it depends on your default FSB speed (which varies by processor).

If you still have issues, does downgrading the BIOS to the version you flashed from fix the problem? If there isn't anything you need in F9, and you're not flashing to fix an issue it solves then I'd fash back. If it isn't broken, don't fix it is always a good rule. I intentionally downgraded from F9 to F6 on my EP45-UD3P as it gave me stability at my chosen overclock, so more recent BIOS aren't always the best option.

Re: Ep45-ud3r bios 9

Yeh id go along with psycho above ,Id probably reflash the old one.I think my own board is up to f8 now but I havent reflashed since I got it.I would if I thought there was 20 mhz in it for me somewhere .
Ive read also that f4 is better for quads:) but that was awhile ago.
If I read F8 was great and had your problem, I might mess around and load and save basic defaults first,then if that didnt work i Might enter the memory timings manually and save the profile then repost,check and see ,had they been reset again..then load my saved profile.If that didnt work I might clear the cmos manually with a jumper.

Then if that didnt work I might reflash to my old one and try reflashing f8 again.Thats just things I might do tho,if I read/heard f8 was really good otherwise Id say "whew close, Im goin back to my old bios until this bug is fixed".
