Changed RAM Setting - Looking for ram BIOS help.

Edit: Initial problem solved, now have access to my BIOS once more after resetting the BIOS. Now, just need assistance with proper voltage/clock settings for achieving 1100 RAM speeds.

Hello everyone, have a problem, not sure the reason - need some help.

Not knowing whether or not this is a general issue that could be answered and solved on the fly, I'll start by giving some simple information.

Gigabyte GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard
AMD Phenom II X4 940 Deneb 3.0GHz
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1100 (PC2 8800) Dual Channel

Etc. Basic information.

I built it a good few months ago, and have for the most part had no issues whatsoever. However, I never bothered to get the RAM running at its advertised 1100, it was always running at 1066 from default settings. The only real problem I ever had was sometimes it would take a long time for the computer to load, but it was hit and miss and simply restarting usually fixed the problem. Today I opened up the BIOS menu upon starting it up to check the settings, and the only setting I changed was I changed the RAM settings from "Manual" to "Auto" - which didn't actually change any of the set voltages or timings to my knowledge.

I'm not extremely knowledgeable when it comes to BIOS settings, but that was all I did. Changed "Manual" to "Auto" and after saving and exiting the BIOS window, I now cannot get my computer to load whatsoever. Start it up, and it sits at a black screen indefinately. No text, no messages, no noises. Everything in the case seems to be running fine, great as always. I'm just not able to get any farther than a black screen.

I've let it sit for as long as 40 minutes, and still nothing. I'm about to run out now for a couple hours or so to see if that miraculously does anything, hopefully getting responses here in the meantime.

So question being.

What the hell? "Auto" was actually the default upon setting it all up for the first time months ago. Why would the automatic settings magically cause the computer to not start up? Especially when they're the same settings they were set to in "Manual"? I now can't even get far enough to get back INTO my BIOS menu to change it back, leaving me, who is not so familiar, powerless to do anything.

Any and all help is much appreciated.

Turn the power off on the PSU, wait 15-30 seconds. Then try and restart the comp.
Incorrect RAM timings is very often the cause of slow booting or inability to boot. You probably need to reset your BIOS.
Yep, clear the bios.

I have that board, give me a sec and I will post a pic of the jumper you need to short.

Edit: here is the pic.



Look up under the video card, you should see a battery. Just to the left of the battery is the jumper. Take a flat head screwdriver or other small piece of metal and touch the jumper with it(both pins at once).

After doing this, I suggest going into the bios and put you manual settings back in. If all is good at that point, then we will talk about overclocking the ram a bit.

Edit: Did the jumper thing, wasn't sure at first whether it was intended to be done with computer powered on or off, but I tried it while it was all powered down because doing it while on seemed potentially idiotic.

Loaded up quick, now have access to my BIOS. Any assistance with proper settings to get my RAM running at its advertised speeds, very much appreciated.

just try taking the battery out... and putting it back in...

No need for that, edited it up - got it back after resetting the BIOS and am now staring at them. Now I just need to figure out the proper voltage/speed/timings to get it running full speed.

Right now it's all running at basic default - 800Mhz, EPP disabled, Auto Voltage. And not sure where to go from here.

Yes, doing it while the power is off is the right way. FYI, doing it with the power on will do noting, it won't hurt anything, it just won't reset the bios in that case.

Now, you want to change the ram settings to manual. Set the first four timings per the sticker on your ram(I'm assuming this is your ram?) - http://www.newegg.com/Product/Produc...82E16820231194 If that's the case then it's 5-5-5-15. As for the rest of the settings, manually set them to the "Auto" setting that's stated in the bios, not the "SPD" setting. This should get it to work at the standard 1066 rating, assuming nothing else is overclocked yet. Once this is successfully completed, then you can attempt overclocking. Also, I see that's a low voltage kit(1.8V - 1.9V) so there is no need to mess with voltages, yet.

I will post a pic of my ram settings shortly, BRB.

Thanks for your help man, I do appreciate it.

Have it set to 1066, running fine, 5-5-5-15 the rest manually set to their Auto listed measures. Saved those settings and have it loaded up. I guess now it's just a matter of getting it up to the 1100. I haven't changed any other BIOS settings since resetting them other than the ones mentioned as has been requested.
Nice, glad you got it working. Upping the "CPU Frequency"(see the top-most setting in the pic below) will up that ram frequency - Note: beware, it will also bump the frequency of everything else on the board, CPU, NB, HT, ect... This is where the playing around and "massaging" of all the settings comes into play. There are some good guides around here, take a look around - here is one to get you started - http://www.overclock.net/amd-general...ing-guide.html

In the mean time, bump that 200 to 201 and look at what happens to the frequencies in the bios, it should give you an idea.
