bios auto settings, RAM voltage?

[fudg3]

I just recently updated to the latest bios ('F10'), which now decided to enable the EPP profile (CAS 4), before it just used the JEDEC profile (I have all settings on 'auto').

But, when I check in Everest, it reports the DRAM voltage is at 1.9V.

I believe the bios should follow the specs as in the profile (2.1V)?

Or could the Gigabyte engineers have a good reason to put it at a lower voltage for this board? Or maybe the reading could be wrong?

Should I just set it at 2.1V manually?

 

I just got a new system, but occasionally (after bios upgrade) I get Windows XP STOP 0000008E errors (BSOD's).

I believe it's quite possible this can be caused due to RAM problems/settings?

 

One of these errors occurred when trying to extract from a password protected Rar archive. An other one was just random while browsing the web.

 

I experienced before that bad RAM can cause copies of files to be different etc.

Can these kind of problem's occur when the the voltage for the RAM is too low? Is it a bad thing the sticks run at 1.9V?

 

I'd greatly appreciate any help / advise in the matter.

 

I just tried setting the DRAM 'Performance Enhance' setting at 'standard', instead of 'turbo'. So far so good.

 

ps; I did run a memtest, which passed.

Please make sure that you have the latest bios and load setup defaults and then set the memory Voltage to 2.1 Volts then set the timings manually to the tested settings for the specific module you have, and test the modules one at a time with http://www.memtest.org to be sure one is not failing. If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

Ok, I could try testing them separately.

 

I believe the bios just doesn't look at the profile to set the voltage.

It just puts it at 1.9V for all profiles (some kind of 'safe' voltage?) (It also doesn't mention '(SPD)' next to the description).

 

Right now I am back at the 5T JEDEC profile, and set the voltage manually at 1.8V. Software monitoring tools also report 1.8V back now.

So I did run this profile at 1.9V for a while, is this a bad thing? Or could I for example also run the JEDEC profile at the same voltage as the EPP profile (2.1V) without damaging it? (in other words: is the voltage independent from the timings?)

 

I believe lowering DRAM 'Performance Enhance' setting did help in system stability. I believe this setting is also known as 'DRAM IDLE TIMER'.

My DS3R is set manually for 2.0 volts. I suggest that you set your voltage for 2.1 volts and go from there. I actually went down to 1.9 volts for a bit, but the computer acted a little quirky from time to time. Don't know if it was the 1.9 volts or what.

 

Anyway, why not just set your memory for full auto (except the voltage) with that motherboard? Mine works like a charm that way.

 

Edit: I have the memory set for "Turbo" in my BIOS. Or is it "Extreme"? Anyway, the hottest setting. I don't know if that matters for a hill of beans, but everything still works fine that way.

Your MB does not support EPP memory AKA SLI Ready memory and the timings and Voltage will need to be manually set.
