hello everyone !

i am trying to do some overclocking with my dual core e 5700 3.00 cpu ( i am relatively new to overclocking but not entirely ignorant :D )

here is my spec

mobo : asus p5p43td pro

ram : no brand 4 gb ddr3 1300 MHz ( some Chinese brand named cheval ) :pfff:

processor : e 5700

psu : thermaltake smart modular 550 watt.

I borrowed a hyper 212 evo from one of my friend to manage heat issue and i set up the cooler properly.

now i know that the mobo is not great for oc but i thought i could achieve at least 3800 MHz on the board. but the problem is no matter what i try i cannot get past 3630 MHz.

my bios settings for oc

Fsb : 242 multiplier : auto (15)

cpu vcore : 1.2750 Pcie clock : 100

NB voltage : auto vtt : auto ( i have little idea about this )

DRAM freq : auto ( 1:2 default ratio gives 484X2=968 MHz ram freq. )
ram voltage : 1.5 v

( C1E : enabled
speed step : enabled
Disabled DRAM Static Read Control.
Disabled DRAM Read Training.
Enabled MEM OC Charger.
Disabled CPU Spread Spectrum.
Disabled PCIE Spread Spectrum.
Performance for CPU Margin Enhancement.
AUTO AI Clock Twister
AUTO AI Transaction Booster ) these settings according to a guide on overclock.net. :p

all other settings auto or default.

i have kept ram timing on auto which is 6-6-6-18.( my knowledge on ram timing is pretty basic )

with these settings i can run intel burn test with 10 pass and 2400 MB memory and prime95 small fft test no problem. temp is around 55 c with room temp 30 c.

now when i try to increase the fsb over 242 no matter what i always get bsod on ibt. i tried 247 even with vcore from 1.28 to 1.33 and bsod within minute running ibt ( no problem with temp ). the bsod code is 0X00000124.

so i tested the ram with mdsched.exe no error.
memtest86+ 4.5 hrs 4 pass no error ( should have run more ).

now i am totally lost. i do not know what else i should do. :??::??:

So i am asking you guys for help. any kind of help or suggestion is welcome.:bounce::bounce:

Sorry for the long post but i want to give as much info as possible.

Thank you.:)

It is what it is; ye cannae break the laws of phsx . .
A 20 % overclock isnt too bad.. .
If you really need more power, just buy Q6600 for 30 odd quid and over clock that aswell . ;#}
You got plenty of head room on that board, the q6600 will go 3 gig on standard volts, or about 3,5 overvolted. 3 gig on q6600's will play almost anythimg. 30 quid? hell, you could sell the 5700 for 15 quid so it wont break the bank.

I would take the 3.6 as a result. To get to 4 gig you need to increase the cpu voltage to 1.45 volts and it wont last long. You could try dropping the multiplier to 14 and increasing the front side bus in incremants to see if you can get past
the current max stable point. Or if you can, change the cpu voltage to 1.35 and try that as well. You might get to 3.8 stable, and call it a day. You have temps headroom for that.

thanks for the reply.

i tried vcore 1.33 with 247 to get 3700 MHz bus but it won't work. do you think 1.35 would be stable and how much temp should i allow 65 C ?

also tried 12X300=3600 but with less voltage 1.31 volt but same result and even no display and bios won't post.
so i have a bad mobo with a bad chip :pfff: :pfff: now i am mad :fou::fou:
