Gigabyte GA-EP45-DS3R OC ?

[rusty]

Hi,

need some help with overclocking Q9450 on Gigabyte GA-EP45-DS3R.
Not sure what volts to tweak to get to 3.6
So far I got to 2.8ghz on 1.27 vcore
List of voltages I have http://spacemaster.sx-team.com/Testo...e/P1020127.JPG
I'm not sure which other voltages I need to tweak to achieve 3.6ghz.

specs:
Gigabyte GA-EP45-DS3R
Q9450
evga 8800gtx
2x2 6400 Red Ballistix
850W PSU

You will need more cpu voltage i'd say :?

try 1.45V - 1.5v DEPENDING what cooling u have


ps: why is there a cpu termination option. who wants to Terminate their cpu? so stupid

I use thermalright 120x. What about ppl, mch core and other options ? Do I need to raise other voltages besides cpu. And what's average safe for the quads 45nm?

[rusty]

anyone ?

[rusty]

need help please, so far I was able to get to 3040mhz on 380fsb

CPU Termination isn't a voltage to be fooled around with. It's kinda similar to CPU vPLL...it can definitely help when overclocking, but I'd suggest raising it only one 'notch' in BIOS, unless you really know what you're doing.

what voltages I should up to get to 3.6ghz ?

Try
Vcore 1.39
PLL 1.58
CPU VTT 1.30
NB 1.44
SB 1.50

with stock RAM voltage, stock timings, stock speed and 2T

go over here to Supershanks thread on this board...he is doing a living review...he has some shots of the bios settings which might help out your situation:

Also, raise your MCH Core (NB) volts to about 1.3v. That's where mine are, and my vCore is at 1.45v on a Q6600 G0 for 3.6GHz (400FSBx9).

Hi, I tried

System freezes, same settings from bios the pc won't boot

I looked at his thread he briefly discusses about some features but not all. Also I didn't find any overclocking tests

[rusty]

ok guys I think I found my problem. It was "System Memory Multiplier" set to "Auto" I overlooked that option. It was increasing my memory from 800mhz to 960mhz when I set it to 2.00D Right after I put it to 800mhz(2.00D) I was able to overclock it to 3.2. I will continue testing today and going up to 3.6. I will report more + pic will be included.

he has links compiled in the first & second pages...click on the appropriate ones to see the bios pics.

I did already but didn't see much explanation to some of the points.
for some reason I can't even pass 430fsb
here's what I've got so far

[rusty]

I was able to get to 3.44ghz @430fsb but it's not stable whatever voltages I use it just won't boot or would boot half way.I think the problem is in ram settings or something else will explore more.

[rusty]

seems that north bridge gets very hot and shutsdown, might need to buy 3rd part cooling and see if that makes difference if it does then it's perfect and maybe even better than ep45-ds4p

here is Supershanks bios template for his settings for an E8500...why don't you put your settings right next to his and maybe all of us, along with Supershanks, can give you some helpful hints...

just remember, there will be a big difference in how high you can take a dual core over a quad core:

partial answer over there.

[ihatbs]

Hi Rusty,

I've EP45-DS3 and seeing the same problems
I can't do more than 3.1Ghz stable, everything else pc won't boot
Tell me how it goes with your new p5q cause i might consider one for me too

[cincyrob]

so should i steer clear of this board? im about to trade in my GA-EP35C-DS3R for the EP45-DS3R. should i pass on this????
i have the E8400, crucial ballistix ddr2 800 mem.
