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.

Added on September 4, 2008, 3:25 amIMO 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.

hmm.. tha manual said disabled d.o.t. if u wanna oc it manually.. use d.o.t. only if u wannna oc from windows. there is installer to do this.
