u computer cannot start normally? care to explain more?

Nah, i haven try OC yet. I just worry that if I try OC but cannot boot as normal, thn wat should I do?

Coz I only got one computer, if it cannot boot as normal, thn I will not able to ask u at here anymore. TQ

oohh..usually i just clear the CMOS data, but if its still not working, i took off my ram for a while, shud be ok after that...

Hi mate, I tried and I failed I follow exactly what it written in http://www.biostar.com.tw/app/en-us/event/tpi45oc/index.htm and finally I failed

What should I do in order to OC? TQ

bro...take a look at this thread first ---> http://forum.lowyat.net/topic/721777
i think u shud use a bigger multiplier and start with much lower FSB, correct me if i'm wrong anyone ...i'm noob too, hope the others will help us here

Hi people, can you guys help me out? trying to OC my rig but failed. reboots 3 times after done setting up in bios..

My rig :

CPU - QX6800
Mobo - EP45-UD3P
RAM - Patriot ram xtreme 4*1gb (800)
GPU - Gigabyte HD4850
PSU - Corsair TX 750w
CASING - Raidmax Ninja
LCD - Samsung 2233sw
HDD - WD 640gb
OS - Vista ultimate 64 bit.

Trying to get 3.6ghz @ ratio 1:1 ! hope you guys can help me out!!

THANKS !!

Try your ownself
In generally,go for 400FSB 5:6 divider and PL5 or so,start from 3.2ghz before moving up

i've tried it myself..

i manage to reach 3.3ghz. then i've some problem.

i tried going 3.4 or 3.2 either way. i'll get the problem reboot 2 or 3 more times after finish setup in bios for OC'ing .

that's why i'm seeking help here.

did u OC ur ram too? if yes, than u better start OC ur proc only, downclock the ram first..u can try pump more vcore if its still not working

easy job.
set ur ram to 1:1 and multiplier to 9x and fsb to 400mhz.
vcore can remain 1.35v or below than that
after u get the pc stable,try lowering down the vcore.

hey overclockers

I need ur guys help..im currently at 475fsb which is 4.03ghz on Q9550 e0 and rite now while typing this, im running small fft on prime95 and the temp for all 4 cores r 80,76,75,79....i need to know if its normal temp after oc..normal idling would be around 50-55

It is fine
Usually application won't push your processor so hard one

Greetings,

Hello I've been a Asus Mobo user since 2 years ago, I was using Striker Extreme and so unfortunately it died weeks ago and I had to buy another one while it's RMA.

So I bought..Maximus Formula II, not very familiar with the interface yet..

Well anyway, I'd like to ask some advice regarding Overclocking as I have some issue..

My spec :-

Processor: Intel Core 2 Duo E6600 2.40Ghz
Motherboard: Asus Maximus Formula II
HSF: CoolerMaster Eclipse (Crappy, I know, lol)
Memory: Corsair XMS2 6400 1GB x 2 @ 5-5-5-15
GPU: Gigabyte 285GTX
PSU: Enermax Infiniti 720W
Case: CoolerMaster RC830

Okay, to be frank I've never been able to overclock much at the days I use Striker Extreme because I don't have the time to do..
Only recently I tried to clock then it died..not from OC though..not sure why -.-

So my real overclocking learning starts with this Maximus II, which I have been facing some problem all along..
I've attached my rough spec below

Problem, is, well, now my rig is sorta stable at 3.4ghz, I can play games and stuffs without BSOD-ing and it's been a week.
However, whenever I tried to Prime it, it will get error within 10mins or worst auto-reboot.

I checked my temperature, not sure if its accurate or not though, 85 celcius degree, it can never go above this as Tj.Max stated 85, but the truth that I learn is E6600 B2 Tj.Max is only 70 celcius degree =.="
Now my question is, what could be the problem? My best bet is the heat issue though -.-"

Sorry for the long nag and thanks for reading =)


Attached thumbnail(s)

my guess is instability.. because prime stresses ur proc and ram to 100% all cores.. no other programs/games will stress ur proc till that high.. i guess thats why u didn't BSOD while gaming or using it..

1.488 is to high for Eclipse.
how bout a change of HSF?
btw plz make sure ur temp is around 60 when prime95.
higher than dat is dangerous.
prime error?
pump more vcore. or mayb ur proc hit the wall already. try 3.2 instead. or lower multi high fsb. but u will need to pump nb volt.

Added on April 24, 2009, 1:40 pmand oso. pump ur nb vold abit. around .1 ~ .2
since ur oced already 1700 rated fsb, i think around 1600 is normal.

Hmm bobiac what do you mean by 1.488V is too high for Eclipse?

And yes, I'm thinking of changing the HSF -.-"

u sure ur rams can do 600mhz r?
follow spd timing summore...

i oso got that ram but 1gx2 kit... 1250@625mhz is no problem . warranty is up to 2.4v.

btw, just wonder does 4g kit got 10000C5DFXMS2 version ?

No 4GB unless 4x1GB
DDR 2 1200 CL5 should take about 2.2vdimm or so eh

guys,

I need ur help abit. Im running Prime95 on small FFT for 24hrs didnt come out any error but when running on large FFT, it comes out error. What opinions do u guys have abt this

This is my bios setup for Q9550 E0 OC 4.0ghz on P5Q DLX

FSB - 475
Vcore - 1.46825
VTT - 1.3
PLL - Auto
NB and SB - Auto

Help me out thx alot.
