Help overclocking e5400 to 3.0 ghz on P5G43T-M PRO

[Leon]

ok so i cleaned the heatsink up blowed the shit out of my pc and cleaned it from dust but now it has underclocked itself on stock when i checked the cpu-z dont know why. it was all stable that day for an hour on full stress test.

now can u check my cpu-id volts

its showing cpu VCORE at 1.18 - 1.19V in the hardware monitor. Should i increase it to go at 3.5 ghz?

 

[Generall]

Trial and error. Just don't too much voltages. Raise FSB along with increasing VCore ( 1.2 or 1.3 is fine ). Also, a pic worth a thousand words.

I even tried 6-6-6-18 and 9-9-9-21 clocks as hasanj mentioned on 260 fsb with 0.30 volts but its still unstable

showing 6-6-6-18 in the cpu-z my clocks show 5-5-5-15 at default when i try to change it.

does more vcore than needed makes it unstable too? although 0.30 is pretty much in the normal range.

btw does updating the bios helps? i didnt update bios since i got my board and it has been an year.

Updating the bios wouldn't necessarily help you overclock better, its basically to cover all sorts of compatibility issues.
Your motherboard just isn't giving enough voltage to hold that 260 FSB overclock..... Bump the volts a bit more and see what happens, if you're able to do that....

 

[Leon]

0.40 is the max stable available, ill try that maybe.

nope, doesnt work with even 0.40 vcore at 260 FSB . I tried changing even the dram timings etc but still doesnt work. its unstable. anyhow am happy with 240 fsb on 3.25 ghz for now as i almost bricked my cpu cuz it wasnt even turning on but recovered it through resetting the motherboard jumper. Thanks all.

not stable even at 1.4 vCore? wtf

kher be happy with 3.25Ghz for now

SpeedStep is is an automatic tech which isn't good when doing overclocking, everything should be at manual. That's what I've discovered so far.
It's basic rule, like AMD CPU/mobo's have Cool"n"Quite tech that too has to be disable when OC'ing an AMD CPU.

Another rule is that, to find out max HT of AMD CPUs we have to drop down the multiplier same applies to Intel CPUs (in case of finding max FSB).

Not if you cant set the Vcore manually in low end Mobos. I cudnt get past 3ish GHz without Speedstep.

Sir Ahsan kind of same prob here. My cpu runs stable on 3.2 with speedtech on but gives bluescreen when off. I am yet to run a long stress test though and maybe i need to keep speedtech on to oc further.

Man your Motherboard's clearly limiting your Overclocking performance of your processor, the most you keep trying, the more you'd be just risking something bad to happen especially since you're running a stock cooler.

People have reached upto 4 ghz with this mobo.

People can but you can't and if you seriously thinking of taking it till 4Ghz on this stock cooler, you may as well fry it in the microwave.

This is the problem,

You see, we've to turn it off to find out max and most accurate "idle" temps. SpeedStep sometimes pulls back the clock as well to give stability.

No. Sometimes it helps to eliminate some OC limits caused by the motherboard.

Agreed. I was trying to overclock an i3 530 on an Intel DH55TC but the memory multipliers were locked. Updating the BIOS unlocked that.

Point being, it still wouldn't help him anyway's in the end.

 

[Leon]

Well even on 3.2 donno why it underclocks itself to stock although its stable :S

i have kept it on 3.0 now. i think its fine there. Thanks all for the help. Mods may close the thread now.

 

[Baghi]

If you're still unsure then I'm sure soon you'll ask to re-open the thread. Anyway, have fun with overclocking and make sure your temps stay around 65 or under and don't let it go over 66C.
Run prime97 for at least 8 hours to make sure 24/7 stability.

Like this:
[8 hour plus Orthos test]

It's my little Celery for daily-use on a P35 motherboard. Temps were still over expectation but yet acceptable.

Good luck.

it may not fry if he is able to overvolt he can i can take my E5200 at stock volt HSF till 3.75GHZ 300fsb 301 and it doesnt even boot to screen voltage barrier for sure

agreed 1.272 is max voltage and my E5200 is bsel moded to run at 3.33GHZ stable as stock at stock and there shouldnt be so much difference i have to set 3.5 using clockgen as intel mobo has nthing to hlp ocing but still i have never seen BSOD

take back my workds for 4ghz i didnt read how much voltage your processor is taking up to reach even 3.5 so 4ghz souldnt be even tried i would say i had experiece of my processor so said it can hit 4
