Plz help me to overclock my e5200 to 3.4 ghz

[Arathian]

Hi,
Sorry if this is in the wrong area of the forum?
I am new to overclocking.I know a fair bit but i cant figure out how to over clock my e5200 to 3.4 ghz stable.I have overclocked it to 2.9 then to 3.08 stable but 3.14 unstable.Ive tryed 272 at 12.5 and 266 at 12.5 but so far they failed.Do i need to change ram timing or is there a setting im missing?Vcore is locked as well.

These are the stats for my computer

p5kpl-cm Mobo
e5200 cpu
I have two 1024,800 mhz ram 4-4-4-12
650 W psu

This is part of the advanced settings in bios

AI Overclocking [manual] / auto
CPU frequency [245] max 333 i think
DRAM Frequency [667] auto 667 / 800

1.8V Dual Over Voltage [1.80]
Vti_CPU Over Voltage [Auto]
1.25V Over Voltage [1.25]
1.5V Over Voltage [Auto]

My brother,about a year ago Had it overclocked to 3.4 but i cannot figure out how he did it,all i have is some scrambled numbers on paper.
This is what he wrote

dual over voltage = manual set mem vott
1.25 over voltage = NB
1.5 over voltage = PCIe voltage

3.6 ghz
ram @ 960? NO!
1.325v ideal
1.4 v MAX
250/260
AI tweaker in bios?
RAM 800 mhz 6x233
1.45 v vcore
1.4v NB
2.1v DRAM
FSB 280
Vcore 1.3v

Any help would and i would be very very great full

See if this thread is of any help to you...

My ghetto guide to overclocking the ASUS P5KPL-CM

... and try the 30% overclock preset (Ai Overclocking set to Overclocking Profile--> Overclock 30%), which will give you a 3.25GHz effective clock (750MHz overclock).

Hey redduc900,
ive tryd the 30% overclock but it failed, worked with the 10% and 20% though.Also i read that awhile ago and tryed to figure it out but it just doesnt make any sense to me becoz im tooo newbie lol i still cant figure out how to calculate the exact number for fsb and multi.As it says next to the multi that i have to have the exact numbers.<<Guessing thats why it wont overclock to the high ghz coz i havnt got them spot on?Or maybe the voltages are wrong or i missed a setting? Also do i need to change my ram timings at all?

 

[redduc900]

Well at a FSB of 240MHz (240 x 12.5 = 3.0GHz) using the 800 DRAM frequency setting (1:2 FSB : DRAM ratio / 4.00 DRAM multiplier), the effective DRAM frequency = DDR2-960, which is well above the modules rated DDR2-800. At that FSB or higher change the DRAM frequency option to 667 (3.33 DRAM multiplier / 240MHz x 3.33 = DDR2-800), and make sure the timings are set manually to 4-4-4-12 at the modules specified voltage. And the "Vti_CPU Over Voltage" option you noted should read VTT_CPU Over Voltage.

Thanks redduc900,
I will certainly try that although im not sure if it will work.Also could you plz have a quick look at this thread and tell me what you think it is from a different overclocking site but it has alot of what i have tryed etc on it..

This thread is From another site though.I hope that is ok???
If not i am sorry for posting it.
Thanks for your help so far.

In post# 11 you mentioned "when i open my cpuz and and go to spd an look at it,it says PC2-6400 (400mhz) i have no idea why when i have 2 corsair 1024 800 mhz sticks..."

Just disregard what's shown in the Max Bandwidth field of the SPD tab in CPU-Z, and instead view the current DRAM frequency on the Memory tab. Multiply the value in the DRAM Frequency field by 2 for the effective frequency, like 400MHz x 2 = DDR2-800 for example.

Yip i got that from two cables post after i posted that comment.
I just set my Ram timing to 4-4-4-12 and tryed 272x12.5 also 323x10.5 and 320x10,Also tryed uping the 1.8 dual voltage to 2.25,and tryed all of those with 667 and then 800 DRAM freq.
That was all with the Ram timing as you said,But none of them worked.
I then re-overclocked back to 3.14 with exactly the same settings but left the ram timing and system became unstable and rebooted.So now i put it back to autodetect (enabled) for the ram timing and now system is stable again at 3.14ghz.
I noticed while i was reading up about my mobo that people have C1E support disabled in the options where the multi is,is this of importence?
and Mem Re-map feature is enabled in the options where i change ram timing,could that be importent?
I didn't try changing the bottom 1.5 over voltage either its on auto... no idea if i should touch that.

What's the EXACT model of RAM (a direct link would be helpful), including the rated timings and voltage at DDR2-800? At 3.14GHz post pic's of CPU-Z open to both the Memory and SPD tabs.

Someone throw this guy their old 4gb ddr2 ram set, poor Lil feller

These are pictures of cpu-z but my computer is overclocked to 3.17 at the moment after turning the cpu freq upto 254/auto multi
Im sorry im not very good on computers and i don't have alot of money,i just like playing games and want the best i can get to help my fps in counterstrike global offensive
as i play competitions.

Also i just read this in another forum "'I've used that board a dozen times for customers. I've always used 800 ram. Your right about the divider and your right about setting it to 667. You've done everything you can for the setup you got. With 800 ram 250/260 is the standard limit that board will go on the FSB. I believe you could get a little more with some 1066 ram, but your better off getting a Asus P5Q instead so you have the full options, and keep 800 ram.


Also on a side note I've seen alot of reviws about the e5200 OC is kinda hit and miss. It may not go much higher as well, but then again you might get lucky and get 4.2. Your best shot would be on a better mobo.

So im guessing once i reach 3.2 ghz im at ends on my mother board atm.I will have to save some money and upgrade.

Thank you all for your help though and if you have any idea's how i could get it back to 3.4 on this mobo any advice would be awesome.
