help with GA-945p-s3

#1

hi
I have a little problem with my motheboard. My mobo is Gigabyte 945p-s3
and the latest bios, when I go into the bios settings after CTRL+F1 I
still cant find Cpu Ration settins or samething similar...I try modify
other settings lika a CPU host frequency, Multipier, etc...and my C2D
e4300 still have 1.8ghz :/ please help, Im desperate.

Quote:

Gigabyte calls the CPU clock setting 'CPU Host Frequency'. This number is
1/4 of the FrontSide Bus frequency. If you wish to overclock your E4300 to
2.7 GHz, set the 'CPU Host Frequency' to 300 MHz rather than the stock 200
MHz. Gigabyte calls the CPU clock multiplier 'Clock Ratio'. Leave the
multiplier ('Clock Ratio') at 9 X (you can LOWER the multiplier, but you can
not raise it above the stock 9 X.) The E4300 must be overclocked by raising
the 'Host Frequency' (CPU clock) because you can not raise the multiplier
('Clock Ratio').

You may need to raise the CPU core voltage by a SMALL amount to overclock.
Do NOT raise the CPU core voltage above 1.4 VDC. Make any changes in small
increments, test for stability after each change.

Ok thanks for helping me but you must know that I tried everything
you said :/ and its not working as should be... I really dont know whats

wrong, I always change Cpu Host Freqency to 300, tried change cpu
voltage, tried chande memory multipier, and always when I push F10 and
save new settins than my monitor stay dark for a 5-10 sec and computer
starts with no overclocking :/ sorry for my english, martin.

Phil,
Don't forget that the C2D, unless specifically told not to, lowers both the
CPU multiplier and the core voltage when idle.
This is called the Speedstep (or Stepspeed, I don't remember) property of
the CPU that enables lowering the dissipated power according to the CPU
load.
Example with my rig (P5W DH, E6600):
Clock = 333MHz (overclocked from 266MHz)
FSB = 1333MHz

When idle:
Vcore = 1.136V
CPU freq = 2000MHz
Multiplier = 6

When fully loaded (Nero Vision encoding a video DVD, CPU load = 99.5%):
Vcore = 1.224V
CPU freq = 3000MHz
Multiplier = 9

All I can suggest is that some setting in the BIOS may be set to [AUTO]
that
should be set to [MANUAL] (or similar settings) to get the overclock
settings to 'take'. You might also use a program like SiSoft Sandra Lite
(free) to check the real CPU speed. Some programs (CPU-Z for one) do not
give the correct CPU speed, FSB speed, and multiplier with my E4300 and
EVGA
680i motherboard. (SiSoft Sandra also reports some incorrect numbers; CPU
core voltage, for one.

The E4300 overclocks I get with the Intel supplied boxed retail
heatsink/fan
are
CPU speed: 2.7 GHz
FSB speed: 1200 MHz
CPU multiplier: 9X
CPU core voltage: 1.250 v (default is 1.325 v)
and
CPU speed: 3.15 GHz
FSB speed: 1400 MHz
CPU multiplier: 9X
CPU core voltage: 1.450 v.

The 2.7 GHz overclock is stable while running Orthos v0.41.110.18.
The 3.15 GHz overclock is stable while running light CPU loads, but hangs
very quickly running Orthos. I also don't like the very high CPU voltage.
Perhaps with better cooling I will get a higher overclock at a more
reasonable CPU core voltage.

As for English: I read the manual (in English) for your motherboard and
it
is difficult for me to understand. It seems almost as if the manual was
translated back and forth among several languages. And some information
is
just missing.

I have all that stuff turned off while attempting to get a good overclock.
The incorrect reports are really incorrect.

Phil Weldon

I was pretty sure you would know about it. Nevertheless I wanted to make the

comment because others might not know about the feature.
Well for me, all that stuff is turned on. But then a 25% overclock (2.4 ->
3.0 GHz for me) is not what I would call a very aggressive overclocking for
a C2D.
Very strange however that CPU-Z is so wrong by you, and completely on track
by me. Chipset not read properly?
I also have problems with Sisoft. Very strange values for the different
voltages (+5V reported as +3.15V for example. Which is totally impossible,
the PC would not even boot).

I have this motherboard. When you try to overclock the processor, the
memory timing automatically tries to change from the default (2.0X to 2.5X)
I overclocked to 3.3ghz but force the memory multiplier to 2.0X I bet that
is the problem, my motheboard will lock up if memory multiplier not 2.0X

afi777,

thank for help , its really working

a set CPU Host frequency to 325

and memory multipier to 2,0- and overclock to 2.6ghz! but....there is
big problem :/ every time when I try close windows and start computer
again my monitor dont start and everything is black :/ I must shut off
the power and after again starting computer back to 1.8ghz :/ any idea
where is the problem ?

afi777,
I have the same problem that you described (CPU returning back to
1.8ghz). It doesn't happen 100% of the time, but more than half of the time
?? I am convinced that it is a problem with the motherboard BIOS. I never
turn my computer off so I don't have to change the BIOS Memory multiplier
back to 2.0X too often. Did you look at the web page (Tom's Hardware) that
I posted on a previous message?? It has some good recommendations for
voltages that might help you get higher speeds. I have a Scythe CPU cooler
and big Antec case so I can push the processor over 3 ghz without much
trouble. I bought premium OCZ memory but it isn't overclocking too well.
The BIOS doesn't allow playing with timing (that I could find). Regards

I discovered that when I change memory multipier to 1.5 , computer

normally restarting with 2.6ghz settigns. but tell me how much its lower
my memory (also system) performance ?

SiSandra XI and H-ODA report the memory running at 5-5-5-15

I know the memory cound run 4-4-4-12 but I can't find the BIOS (F10)
settings for memory on the Gigabyte GA-965P-DS3
