E4500 OC Problems

post #1 of 6
Thread Starter 
Hello guys,

The store I've bought my PC at overclocked my E4500 to those settings:

CPU Host Clock Control: 11 x 280 (3.09Ghz)
System Memory Multiplier: 2.4
CPU Voltage Control: 1.3875V

Since than i've upgraded my bios couple of times and lost my OC settings.
I've tried to OC by myself to the settings above and also to other speeds, but it's just not effecting my system performance.
also when i check it in CPU-Z i see no difference. ***?
maybe it's something in the "MB Intelligent Tweaker" in my BIOS that i'm not defining right?

help plz...

just start from scratch again.
this is a very basic explanation of overclocking

its basic maths. your E4500 is rated at 800mhz. you always divide this number by 4 so 800/4= 200, this is your FSB. (or cpu frequency)
then your processor (cpu) has a multiplier of 12.5 (or cpu ratio)
so 200 x 11= 2200mhz or 2.2GHz, your stock speed

boot into bios, disable C1E, Speedstep and any other power saving settings.

unlink your ram, so it stays at stock speeds, you can overclock the ram later.
this means leave it at 800mhz, 667mhz, whatever

can you raise the fsb? yours is now 200. try rising it to 220, press f10 (usually to save and exit).
boot into windows
download realtemp and coretemp (google them)
install and run them
then download intel burn test (ibt) and run it.
have a look in task manager and notice how much free ram is listed.

in ibt set threads to 2 (for 2 cores) and then click on custom ram and enter an amount just below the free amount.
eg. i have 2520mb free ram. so i enter 2500 into the custom ram.
run the test for 5 passes. for now,
and at final overclock speed, run it for 50 passes.
keep an eye on temps (do not let it go over 80.c)

or download prime95 and run the torture test/large fft's

if test runs fine, go back into bios, and change frequency (fsb) to 240 and repeat the tests.
keep doing this in 20mhz steps until windows will not boot. then just go back a step (remove 20 from the fsb) to the last stable frequency,
or
just raise the cpu voltage a couple of levels. it should now boot.
its a balancing act, higher voltages will get you higher fsb, but it will also give you higher temps.
max voltage for a E4500 is 1.5v (in cpu-z)


the trick is to do this step by step, just take your time.

thnx for the answer j.col!
i did what you've said: "disable C1E, Speedstep and any other power saving settings", and it fixed the CPU-Z problem!
but what about the voltages? should i modify them or leave them on "auto" (normal)?

The CPU-Z "problem" is a power saving setting when you run your cpu at stock clocks. It'll jump up to 2.2 Ghz when in use.

The maximum vCore that processor can handle is 1.45. If they were reaching 3.9, odds are they had it pumped up to that. Give it a shot.

Don't add voltage unless you're not stable at your current OC speeds. Test with Prime95, LinX, games, etc. Most E4500's will do ~3Ghz on stockish voltage. Going above 3Ghz is where the voltage will need to be increased dramatically to where most would top out around 3.3-3.4Ghz.

this^^^
just stress test now. and if its stable then you dont need to raise voltage.
