Need to overclock an Intel E7400 2.8Ghz!!! Please Help!

post #1 of 6
Thread Starter 
Hey guys...Im totally a newbie here and to make matters worse Im a total n00b at overclocking computers. So, I come here for help as I really would like to overclock my CPU i.e. my E7400. As u can see below my Pc is not much of a rig but it lets me play games like Crysis, Crysis Warhead, GTA 4 LCS, Dirt 2, Black Ops etc. most of them at High settings(not Ultra or Very High)...but even at high setting I lag a little bit for like 2 secs after about every hour of gameplay (Crysis Warhead and GTA 4 LCS). I was wondering if it could be my GPU, but figured it was not and infact it was my processor. When playing these games, the CPU load is around 97%......!!! B4 overclocking though I would like to know if it really is my processor that is causing the lag...!! If it is than please explain in detail what I should do to bring up processor speed upto at least 3.6Ghz if possible. And btw the temp of my processor is 39*C even when idling... is this normal??? Because I have applied Coolermaster High performance thermal paste and if u check out my cooling system below...I think its not so bad(not bragging) and even when the processor load is at around 97%...the temp hardly rises above 42%!!! Any help would be greatly appreciated! Thank You!

this is a very basic explanation of overclocking

its basic maths. your E7200 is rated at 1066mhz. you always divide this number by 4 so 1066/4= 266, this is your fsb. (or cpu frequency)
then your processor (cpu) has a multiplier of 10.5 (or cpu ratio)
so 266 x 10.5 = 2793mhz or 2.8GHz, your stock speed

unlink your ram, so it stays at stock speeds, you can overclock the ram later.
this means leave it at 800mhz or 667mhz, (download cpu-z, this will give you all the info you need about your pc, fsb, ratio, voltages, ram speed, ram timings etc....)

can you raise the fsb? yours is now 266. try rising it to 280
boot into windows
download realtemp and coretemp (google them)
install and run them
then download intel burn test (ibt) and run it.

in ibt set threads to 2 (for 2 cores) and then click on high or very high test.
run the test for 5 passes. for now,
and then at final speed you want, run for 50 passes
keep an eye on temps (do not let it go over 70.c)
this is extreme and in gaming you will be at least 10-20.C cooler

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

if test runs fine, go back into bios, and change frequency (fsb) to 300 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.
your E7200 is safe upto 1.36v

as you have 4 sticks of ram, you will have to raise the NB (northbridge, it may say mch) voltages a couple of notches

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

when you reach a point where you cant go higher, it may be worth dropping the miltiplier from 10.5 to 10 or even 9
i had to do this on mine


edit. in future, use paragraphs, its easier to read
and welcome to the forums
if you have 42.c under load, then you have some headroom.
imo you need your cpu at least at 3.2ghz to reduce lag.
also most new games use 4 cores now, so overclocking may still not fix the lag

Before I had SB, I got my E7400 to 3.9Ghz with a vcore of 1.39. It still was pegged at mostly almost 100% cpu usage in games while my gpu was under 95%. After I upgraded cpu usage isn't even nearly as high, and now my gpu is always over 95% so that cpu for current games will bottleneck. BTW, my gpu back then was a 4890.

Thanx a lot 4 the reply...but just 1 thing, actually my processor is the E7400 and NOT the E7200...!! So does that make any difference?? or is it just the same?? And also..if OC'ing will not solve the lagging problem..then is there any point in overclocking at ol? Will I notice any differnce peformance wise after OC'ing then?(Thats the whole point of overclocking tho... )

Doesn't make a difference. The only difference between the 2 is base clock speed i believe.

Thanx a lot for the replies but just 1 more question.......Overclocking from a software and overclocking through the bios....is there any difference?
