Hi everyone,

As I am struggling to make my memory work in a stable way, I find that
ther is something I don't understand in the BIOS of my GA-EP35C-DS3R.

Just above the memory speed setting, there is a "performance enhanced"
wich is , by default, turned to "turbo".
Choices are:

Standard
Turbo
Extreme

My habit is to leave the default setting since it is often the best way
to have a stable system.

But what this setting actually chanes?

Knowing that I will use my PC as a music workstation, I will need
stability even more that speed.
What I want is that all components run asfast as they where intended to.
Should I turn back to "standard"?
Obviously, I will try it out, but if enyone has a clue about the meaning
of this setting, I'd be glad to hear it :=)

Thanks for resaing.

Huey

Since those settings are seldom documented in any detail, there
is no way of knowing what they'll do to your board. Many times,
people are greeted by a "black screen" and a failure to POST,
after selecting them. That is why I leave crap like that alone.

I could'nt agree more.
I woudn't even ask about it if the default setting was "standard".
If it is standard, for me, it means that it should be "default" as well.
But no: default setting is turbo.

:-/

With everything you explained in the other thread, I am tempted to take
for granted that if you don't know what this setting does, nobody knows.

On one of my boards, a selection of Turbo forces a CAS2 setting
on the RAM. Which is fine if you happen to own CAS2 RAM. For
many people, instead they are greeted by a black screen for
their troubles. If a setting cannot be documented in any
reasonable way, then that setting is a "roulette wheel".
Personally, I prefer dialing the settings that have known
functions. If I want CAS2, I set it in the CAS adjustment,
not "spin a roulette wheel" and have some unknown combination
of settings applied.

Note that some motherboards have adjustable voltages for the
chipset, and in some cases, the application of some of these
OC settings, causes abnormally high voltages to be applied
to the chipset. There can be a lot of monkey business going on
behind the scenes. It takes a lot of hobbyist labor, to
figure out what the hell is going on, and not every board
gets a thorough analysis.

I'm fairly certain they just apply a template of overclocking across the
board, basically for those who don't want to take the time to tweak
settings. I'm surprised the default is turbo.

I think I read each setting is a % overclock, but that was a similar feature
for an ASUS board if my memory serves.

I guess if you want to note the standard settings, then reboot to another
setting you could see for yourself ;-).

Not very informative, but that's the gist as I understand it.

Thanks Onsokumaru. Actually, there is one thing that setles it once and
for all:

- in order to make my new memory module *actually* run @1066MHz, I have
to set their clock myself, thus bypassing the default setting induced by
JEDEC specifications of the motherboard. When I do so, the BIOS
recommends with a red flashing message, that I chose "standard"
performance enhancement instead of Turbo. So I did, and everyhting
works pefectly. This settles it :)

As I donot want to fix something that is not broken, I will simply
ignore the default setting and stay in "standard" .

From what I read, many Gigabyte Mobo have this strange parameter
(performance enhance). But many of them have a default setting that is
"Standard".

My GA-X48T-DQ6 has this option too and it is set to extreme and seems to run
just fine. No doubt the processor used will affect the optimum setting here.
