Overclock e8200

post #1 of 4
Thread Starter 
Hey.
I'm new to this forum and I was looking for any kind of help regarding this matter.
My cpu is sitting at 3.6 ghz stable with 1.175 voltage 450 fsb
my ram is corsair dominator ddr2 8500 they currently at 1080mhz if I'm not mistaken.
My goal is reaching arround 3.9 stable and getting the ram to 1:1 ratio. I should be able to accomplish this by just increasing the cpu voltage or is there anything else I should change?
Also I've searched a while for the benefits of getting the fsb to 1:1 but I have found nothing, could any of you enlight me.

Thanks in advance.

Please fill out your system info here:

What settings are you running now other than V-Core.

Honestly im rather impressed with the amount of vcore your running to get that high of a clock on your chip, however, how have you verified that your stable? You will most certainly need more vcore to achieve your desired overclock, as well as a few other settings.

I recommend using Realtemp as a temperature monitoring utility, in conjuction with Prime95 for torture testing to ensure stability. I suggest 4 hours of small ffts to start to rule out vcore instability, and then at least 4 hours of blend. 8 hours of blend can achieve similar results, but may take longer to show that your vcore is too low, and is a bit harder to troubleshoot.

As far as 1:1 ratio goes, its not necessary, 5:6 generally gives better results, as does lowest possible timings and highest possible ram frequency.

The hardest part for you is, dependent on what motherboard your running, is getting near the 500fsb mark. Not all boards can go that high, and being that your multiplier is locked at a max of 8, your reliant on your fsb to push your OC higher.

running on 1:1 ratio lessens the stress on the nb and it also helps if your ram cant hit the speeds you need from a higher ratio, this was the case for me as my ram stopped my e8200 oc @ 540 fsb.

450 is pretty easy with most good boards and its only as you get above that you will need to alter more than vcore. mch volts, refs and clock skews will need to be played with and maybe even some ram sub timings to get 100% stability.

3.6ghz was for me the point at which i needed to really ramp up the vcore as mine would do that on a little less vcore and it used to run most of the time 7x499 on under 1.1v.

great chips the e8200s and very under-rated, i just with i had the ram to really see how high mine would of gone as it craps out on me @ 540 :/

I've ran prime95 and some other software I can't remember when I overlocked my cpu, which was arround 2 years ago, as far as I can recall, it was perfectly stable plus I has been running at clock/voltage since then and didn't give me any trouble yet.
As far as the ram goes, I think the ram will be arround 1200 mhz or 980 If I apply 490fsb. I'm afraid I won't run at 1200 unless I get it to 2.3 or something voltage which I'm not sure if will be that healthy for daily use.

Edit: I just changed the vcore and nothing else and the rams are running at 2.1v

I've reached 4.2ghz once to do a benchmark, didn't try to get it higher, but it wasn't that sure if my cpu would fry if I kept that overclock for daily use.


Thanks for the replies guys. And thank for enlighten me on the 1:1 ratio

(I've already updated my specs info on my profile)
