i dont oc at all...i just disable the c1e...

that proc is running at reduce speed, will bump the multiplier once on LOAD state.

but ur temp is something wrong... way too high for a 45nm proc. my OCed quad full load only 68C max...

try realtemp la bro.

any temp monitoring software can be used. just set TJmax to 100C. intel recently released the spec for 45nm proc.

http://intel.wingateweb.com/US08/published...MTS001_100r.pdf

go download coretemp version 0.99.3

its updated for 45nm edi

cannot yet wor....
full load only 77c @ 4.2GHz
but it's fitted with Tuniq Tower 120

well its real high....i think maybe the stock heatsink not sit properly....btw im using the stock heatsink thermal paste, which i believe not really good...

maybe ur case airflow is bad...

do like me..full stress on aircond..set to 16c
open side panel,use intelburntest to stress..temp around 66c-68c~

nono its not about surrounding or what....just changed the stock heatsink to geminii.....idle 27-29 now...

hehe

Hi guys, newbie here 1st post

Just some quick question about overclocking my new pc

I had disabled C1E and Speedstep, but my proc will still auto downclock when idle(6*400fsb instead of 8.5*400fsb), is this normal?

also load line calibration? enable or not to enable??

overclocked my q9550 to 3.41Ghz @ 1.26vcore, temp is around 62c(load) BUT my nb temp is at 70c(idle) and 87c(load) during prime95 test. How far sifu recommend nb temp to be? 87c is scary ler

My Pc Spec:
Q9550
Asus Maximus 2 Formula
4x 2gb kingston hyperx ddr2 1066
640gb wd hdd
2x HD4870 cfire
CM cosmos s

really nice system...

yes, it's normal eventhough it shouldnt happen. on my X3320, it doesnt happen when both off but doing that on E6600 with same setting. kinda weird...

do u increase vMCH and vFSB? Maximus has heatpipe covering the NB/SB/Mosfet area, it should be that hot. how your case's air circulation?

thanks, so is 87c in nb fine?

haven't really temper vmch and vfsb YET, they are all auto. Newbie ma so giv me some time to test

as for air circulation, what do you recommend i put? currently got 1 front, 1 top, 1 side and 1 rear. I'm going to buy another 120mm fan for better circulation (still got 1 space left for top)

Front - Intake?
Rear - Exhaust?
top - Intake?
side - Intake?

my e2180@3ghz@1.365v idle at 37'c on stock cooler.
is that ok???

Yes, that's normal You should worry about the load temps, not the idle.

well it load at 72'c max.....
i think that is kinda high..
what u guys think..

If you're on a stock cooler then it's around there and maybe lower if your room is not too hot Air cond helps.

Added a new 120mm fan above and in front, Nb temperature decrease from 87 to 84 (load) and idle at 73c any northbridge cooler to recommend, pls recommend sth tat is selling in lyp

My air circulation setup - 2 Front Intake, 1 Side Intake, 2 Top Exhaust, 1 Rear Exhaust.

some questions for overclocking:
for a quad like q9550, recommended temp is 65-70c? My proc overclock a bit only temp reach up to 65c load, using zalman 8700 here
also nb voltage(vmch i think) should not exceed how many volt?

Edit: Found out why nb temp so high liao, its because of the thermal paste.. Problem solved, now nb idle at 68, load at 76c yay

usually people stay below 55c for nb temp

i tried everything, even without oc my nb temp is at 62 idle

read about some review saying it should be fine under 80c. 90c is the limit

what temp u guys got for ur nb? do u think the reason why my nb so hot is because of i have 4 pairs of ram and 2 pair of g/c which are putting stress there?

Hi All, need help in ocing my rig.

i manage to ocing my e4600 to 2.822 (235 x 12.0) but everytime i try fsb 250 (3.0) it pass the POST but when come to the window, it will then restart the computer. is that mean not enough power (PSU: cooler master extreme power 460W). need your help!

my rig as in the signature below.

thank you,

My OC image

up vcore?

I had tried up the vcore from 1.288 to 1.35 still keep restarting the windows....go into loop

wats u Ram voltage and NB voltage?

All i leave it to auto for now.....

its either ur rig not enough juice or ur ocing not stable.
try to borrow true power PSU then test it on ur rig.
other than that, read more on the ocing tips and tricks to solve the instability prob...

edit:
just saw u use 3 HDD, might be causing not enough power to ur rig.
later kaboom~!!

dont let your ram timing = auto

Coolermaster 460W is more than enough on that processor, even with 3HDD - and the instability is without load at all, so we can't blame the PSU.

If Vcore is up and you adjusted bridges and RAM, then you've probably reached the threshold. Not all processors are created equal.

Besides, are you even sure its stable at 235x12? And you're going from 235 fsb to 250 fsb in one jump?

I recommend you stress test for a few hours as 235x12, and if looks okay, stress test some more, maybe half a day while you're at work/school/out with gf/watching a movie/going clubbing/riding your bike/worki...nm....if you're cool, then adjust the fsb by 5Mhz and try it again.

If your system isn't even stable at 235 after stress testing, then there's no point trying to go up - which is probably why at 250 you can't get far.

If you can't do it in small increments, then stop there. You should be happy with the free performance gain.

And please monitor core temps.

Timing auto should be ok if you use a suitable ram multiplier

try up ur vMch voltage....then try set ur ram timing 5-5-5-15 on 800mhz...

thanks for the guidance. I had tried to up the vcore voltage in the bios to 1.3125v, but when boot into the windows, the cpu-z still showing 1.26-1.288v. as for the fsb i had stressed test (fsb 235 x 12.0) for few hours now and it is working fine in the test as well as playing games. but it can't pass 236 fsb with the voltage set to auto, but if i set it manually the voltage isn't show any changes at all. it will boot pass POST but when come to windows boot screen, it will run a while then restart the window.

do you think i should lower the multiplier to 10.0 to try higher fsb or it will not working as well?

thanks

Added on September 4, 2008, 12:39 pmHi all, one more question regarding the vcore vs vid. i had read some article on this but it is still very confusing to me, i set the cpu voltage in bios at 1.35v but in cpu-z it only show 1.288-1.312v. the intel spec say the vid is between 1.18 - 1.312, so is seeting 1.35v or more in bios okay for the processor?

hi all, i am new at overclocking, if my oc pass the POST but reboot when come to window, what does it mean, is it i had reach the limit or the problem of the voltage. I also tried to set the voltage at 1.3v but the cpu-z only show 1.26-1.288v (is it because of the vdroop)

thanks

increse vcore....still not stabil if got bsod.

Some People Say Celeron D After Clock Is better Than Dual Core Without Clock Is It Real?

i suggest u read thru this guide

http://forum.lowyat.net/index.php?act=ST&f...0#entry15451675

i just use the intelburn test. if u passed the linpack test, does it mean that your com has stable?

87c is too hot. It won't damage the nb outright, but over time, not so good. Did you increase voltage to the bridges? It will be okay if you run a small 40mm fan on it - most users who get high nb temps will go for a fan, putting a fan near it, is not exactly the same is running a fan on it - so try that. Also, check to see if your heatsink is properly mounted on the nb - you might have to remove it and reapply thermal grease and try it again, if the fan isn't working, I have a feeling your heatsink is the problem.

IMO too high. OCCT sets a default alarm when temps go past 70C for stress testing - so your rig would set off the alarm.

Keeping it under 65C is better, and most users can get below 60C even on the stock cooler. If you're using the stock cooler, you need to upgrade to something better, or run a better cooling setup in the case.

Did you increase the vcore? If so, that's why it's running hot. If you can't upgrade the cooler now, you'll have to reduce the overclock until you can, otherwise your processor will spoil or lose performance. The components get derated when exposed to high heat, so performance will also go with it.

Also, are you running it in an air-con room?

25C set on my aircon, and I can run 50% overclock on my E6420 under 58C with a Zalman Cooler. To me that's pretty hot, and I'm already trying to figure out why I can't run it cooler.

Hi, I'm a newbie at OC. Need some help with my rig.
I achieved 3.71(413x9)G at vcore 1.3v for E8400 with RAM latency at 5-5-5-15, vRam 2.0v. However, i can't go pass 413 for my CPU even if i lowered the multiplier to 6. Tried increased vMCH +0.1, or CPU VTT +0.1v but to no avail as well. System stable with temp at load 52-53oC. Please advice how to increase the FSB of my CPU. I read about my cpu- it can go for 520-530 for FSB. Thanks.

My specs is in my signature. Thank you. (PCI E set at 100)

Hurms, my E4400 can stable OC @ 333Mhz*9 @ 1.35VCore, pass IntelBurnTest.
Daily use 356Mhz*9 @ 1.4625VCore.

thats weird case... but i dont think p43 is that bad gua...

could it be ur ram holding u back? try add vdimm to 2.1v n see if it can go above or not...

reduce ur vmch n vtt back to stock again as simply add voltage to these might cause harm...

and iirc gigabyte didnt state how much is the value =.= this mobo have value for vtt n vmch?

thanks tkh. My RAM is Kingston HyperX DDR2-6400 2G kit(5-5-5-15)--> regretted. I will try to increase the vdimm and see. and of course lower the vMCH and VTT. Would increasing PCI E help?(101-105)

---

Added on September 5, 2008, 7:13 pmMy stock vMCH is 1.1v, CPU VTT is 1.2v. It doesn't work with increasing the vdimm to 2.1v. Got anything to do with MCH frequency latch, or SPD? I set it at 400Mhz for strapping and 2.0B (2x333) for SPD. It doesn't work with 2.0D (2x400). Thanks again.

oh ya bro... forgot to ask, did u set ur ram divider to 1:1 ?

not really sure pcie clock wud do... but its advised to put it on stock 100..

yes. ratio 1:1. i put my PCI E at stock 100. Could it be the strapping and SPD? Thanks bro.

Adjust ur RAM timings...my cheapo rig goes up to 3.4 b4 I hate it 4 its heat. So, any successs?

passing POST doesn't mean your system already stable. loading windows is a bit more stressful than just system POST, so any instability may be instantly occur.

just as basic.... increase more voltage when something is not stable. which voltage? trial and error.

originally from here, post#50

i want to do so, but i cant. my bios voltage setting is read only. wonder why.


i wish i can adjust the voltage.. i see in ur sig, u also use msi p35 neo3 mobo right? can teach me how adjust the voltage?
another thing is i need to enable intel eist, if not, got bsod after windows boot screen with code stop:0x000000f4.
why this happen??

maybe its under some control setting or something.

teh voltage can be easily adjust in the overclocking page there ah,why leh?
can u post up ur bios screen here and see whether same like mine?

here from bios, under cell menu(from pdf manual, dont have camera to take picture);


that grey in color is read only.
setting that i use now is d.o.t. disable, eist enable, spread spectrum disable.

try enable the dot setting.
