hi guys. want to ask for some advices here.
i just got myself a Q6600 G0 rig with stock heatsink fan, 2x1GB DDR1066 Kingmax, Asus P5E, CM Real Power Pro 550W in a gigabyte 3d aurora full alu casing and good cable management.

i want to know if i use the stock hsf for now, at what frequency is it save to push my cpu to? i'm running it in a non air-cond environment.
is 3.0GHz doable? will it be ok with stock hsf and tuniq tx2?

if it is, what is the recommended vcore for the cpu, the bus speed, multiplier, divider etc to achieve it?

thanks in advance for all the advices.

if i were u i wouldnt dare to OC a quaddy wif stock HS. even with best third party cooling will generate more than 60~70c temp. change HS 1st then u can think about OC.

icic... will probably buy an aftermarket hsf but not so soon. just not sure which good hsf can fit my mobo nicely since the surrounding areas of the cpu slot have copper heatsinks. worry they will get in the way.

those big hsf all looks super heavy... hope it will not strain the mobo even with the back plate on.

oh, cm hyper 212 not heavy? it looks huge though...

You have to test it for yourself. Set stock vcore, then pump up the fsb to see how far it'll go. I'm guessing 3GHz should be quite do-able. Anything more than that, it's your luck bro.

last night, i ran prime95 at stock speed.
highest temperature it hit after running for 5 hours plus is at 59C. Is it in the normal range of temperature using the stock hsf?
idle is around 36-37C

1.2kg... wow..
but anyhow, planning to change the hsf sooner or later also. coz i noticed that the stock hsf seems to be making a humming sound when it spins faster. not quiet enough. want it to be super quiet brows.gif

so what will u guys recommend if i want good hsf but very silent 1? something around rm100 will be good, or less than rm150 la.

CM Hyper 212 = RM130.00
Arctic Cooling Freezer 7 Pro = RM140.00
CM GeminII = RM110.00

But if you want super quiet and want to OC, get CoolIT Freezone  tongue.gif
oh GeminiII and CoolIT Freezone is it? don't know how they look like. let me google them up


Added on May 16, 2008, 11:27 amjust read up on GeminII and Freezone.
GeminII is so huge... not sure can fit into my system without the GC getting in the way or not
as for Freezone, it's way off my limit. no need that super cooling for such a high price tag. moreover, the review i read said that it's quite loud if the fan is run on higher speed to get very low temp. don't want another noise system...

this is the view of my rig through the side panel

think the GeminII can fit??
btw, how much is this GeminII anyway

i wonder how come you guys can set the vcore so low and yet prime stable.

i just changed my Q6600 G0 stock hsf with hyper212 and changed all my 3d aurora fans to the 90cfm fans (2 exhaust, 1 intake).

I tried several settings to achieve 3.0GHz
bios vcore 1.325v 9x333
vcore 1.325v 8x375
these 2 setting, i can prime stable around an hour plus only... then my pc hung.
load temp shown in core temp is 63C

i bumped up my vcore to 1.343v 9x333
this time, i can prime stable for slightly more than 3 hours. then pc hung again...
load temp in core temp is 65C

btw, i primed using the second option where it says generates maximum heat, most power consumption...

the only 2 things i changed were the multiplier and vcore settings in bios. others left as auto. is there some other voltage i need to change to get it stable? what is this vtt in my bios?

maybe i will try 1.400v and test again tonight. but any other suggestion from u guys?

should i prime using the small FFTs or in-place large FFTs?

Small FFTs.

Well, I played games with 3.01Ghz for 2-3 hours and I didn't find any problems using Auto except the FSB plus my motherboard natively supports 1333mhz bus.
*
mind telling me the actual difference between the two options?

btw, last night i bumped up my bios vcore to 1.375v and primed with large FFTs

9x333. primed over 8 hours and no errors, then stop d.
8x375. primed for 3 hours and no errors then i stop it coz need to come to work this morning.

core temp shows 68C 68C 65C 65C

maybe tonight run again with the 8x375 @1.375v setting using the small FFTs this time.
if can run more than 5 hours, i think should be fine already right?

maybe can try 8x400 next haha. dont know can push that much on the fsb or not

Yeah, small FFT's will test very little RAM and mainly stress the CPU, very good for ensuring CPU & Mobo stability at a particular OC without really testing alot of RAM. Large FFT's will stress lotsa RAM and also the CPU and Mobo. So for lazy ppl like me, I just straight run a large FFT stress test...lol..

Darkangel...the FSB speeds that your OC will be stable at depends largely on your mobo....what mobo are you using?
*
I am using P5E.

QUOTE(Thrust @ Jun 24 2008, 11:31 PM)
What's the advantage of running at 8x400Mhz instead of 9x356Mhz to achieve 3.2GHz clock speed?
*
If i'm not mistaken, higher fsb will be better coz the data rate going to your cpu will be higher. as an analogy, i think it's like a road at the gate of the cpu and the higher the fsb, the more lanes of road u will have into your cpu. that's what i think la... not sure accurate or not haha.


Added on June 25, 2008, 10:21 ami tested priming using small FFTs 8x375 @1.375v.
primed for over 6 hours and no errors.

is it safe to say that i can run at this speed at the 1.375v level stable?

Here is my q6600 O/C to 3.7Ghz prime95>7hrs stable, quad damn hot over 1.5v  sweat.gif i think need at least bump 1.6v to get 3.8-3.9Ghz
*
this also u complain hot d?
my Q6600 G0 at 3GHz (375x8) @1.375v and my coretemp showing 68C already... i'm using Hyper212.

ur ram can go around 46xMHz. is that ddr 800 or 1066?

what's your q6600 vid?you should use x9 multi for higher clock
*
vid is 1.325. 9x can go for higher clock but needs higher vcore also right?


QUOTE(TristanX @ Jul 1 2008, 12:38 PM)
I noticed there are >3000rpm case fans. Maybe that helped a lot on cooling because the airflow is probably a lot faster and possibly an air conditioner.
Try adding more intake and exhaust fans.
*
already 2x120mm exhaust and 1x120mm intake case fans. no more bracket to put more...

QUOTE(jeromeccm @ Jul 1 2008, 02:52 PM)
just sharing...

my Q6600 running at 1.42 Vcore, 400X9 = 3.6G
Temp idle = 43C, Load Max = 60C

heatsink fan: Xigmatek Scorpion
Therml past (very important!!!!!! MX2 or Tuniq)

i used to use capalang thermal past.. temp was 65 at 1.37 at 3.2G.. but now can go somemore... woohoooo rclxm9.gif

credit goes to cstkl1.. he thought me how to OC my processor with the Biostar I45..
*
ur temperature is captured using what software? when i use coretemp, it's much higher than my ASUS AI Suite temperature. so which is real?
I'm also using Tuniq for thermal paste.

You can put another at your CD/DVD bay. hehehehe

oh no dont want that. i'm using 3d aurora which has a door panel that closes the front hiding those brackets behind.
dont want to put a fan there and leave the door open. i think lots of dust will go in

i encountered a weird situation just now, i trying to achieve 3.5ghz by setting 437*8 @ 1.44Vcore (prev tried 1.40V but failed prime95 just after 1min), testing with the setting on prime95, no failure after 10min but temp went up to 70C, dont know why during the test, my vista suddenly logged off (like in proper way, closed all the program and shutted down), i thought maybe it setting somewhere in bios to shut down the system when reaching certain temp, but its not, i mannually set the limit to 80C, and log on into windows again and re-run the prime95, but still same, after about 10 min, without any error on the test, the system shutted down by itself, really weird la, can some1 tell me whats going on here?
*
maybe u have a temperature monitoring tool running which is doing the auto shutdown when it reaches certain temperature?
