Noob Overclocking

So I have a few noob overclocking questions. I have an E2180 overclocked to 3.2 GHz with a dropped multiplier so that I can maintain that speed at a 1:1 with DDR2-800 RAM, so 8x400FSB. I haven't taken the time to do extensive testing to find what the right vcore is so I just bumped the voltage up from 1.2 stock to 1.45 just to be safe and it can run 12+ hours on Prime 95 easy. I would like to see if maybe 3.6 is possible, it would be the next step up from 3.2 if maintaining the FSB ratio. However I can get it to POST but not load windows. My question is what would be the next step from here to attempt 3.6 GHz? So far I have:

1) Increased FSB to 400 MHz to be in a 1:1 FSB:D RAM ratio for my DDR2-800 RAM.
2) Dropped the multiplier from 10 to 8 to achieve a stable 3.2 GHz.
3) Increased voltage to 1.45 while staying within Intel voltage specs to ensure stability.

There are a few other options I've heard, one of them being a Northbridge voltage increase. How would this help? Why would increasing Northbridge voltage rather than CPU help? Or should I increase CPU voltage?

dont bother about it too much. the E2xxx chip max out at 3.4Ghz while 3.2Ghz is good. those chip is really bad quality binned chip, they are physically limited.

if you insist you can try up the FSB further and just up the NB voltage by 1 notch. if fail in prime up the vcore until its stable. make sure your ram is stable as well. leave it on 5-5-5-18@2.1V

whats your full system spec?whats your load temp?

E2180 @3.2 GHz (8 x 400 MHz FSB)
XFX 780i MB-780-ISH9 Motherboard
8GB Patriot 4-4-4-12 CL4 DDR2-800 RAM @2.2V
BFG 9800GTX 512MB 256-bit Graphics Card

My load temp under Prime 95 is 56 C plus or minus a degree. I can get it down to 53 with SpeedFan.

3.2 is a great speed out of an $80 chip. You can play around with it a little more but I would be happy with those results.

i can see another problem. that is the 780i will be very very hard to OC above 400FSB. i will be happy and stay with that CPU.

you can keep going to get more out of it. but dont come back here and say you cant get it stable. because both the CPU and mobo has there weakness in OC at high FSB.

If it really takes 1.45v just to get to 3.2 I don't think so, but go for it and let us know how you did.

I have got my e2160 to to 3.6Ghz on air and it was Super_Pi 32m stable but I needed a notch over 1.5v to get there which is too much and a quick blast of Intel Thermal Analysis Tool revealed dangerous temperatures of up to 75C. If I water cooled it would be fine I suppose. I knocked 5 minutes off my Super_Pi 32m score which was cool.

Normally it does 3.2 - 8x400 fsb at 1.30625 in the bios, the bios default is 1.25v, the highest fsb I have tested stable was 413.

as said from above. going above 3.4Ghz will going into extreme value in both temp and vcore.

your call dude!

Ok few things I didn't mention. I'm perfectly happy with the chip. I mean I was expecting 2.8 max when I bought it but I even got it in 1:1 and I only paid 60 bucks for this thing. I also don't want to exceed 400 FSB (I've been able to boot Windows with 460) because I want to keep the 1:1 with my RAM and most reviews on my RAM can't get it OC'd past 420 FSB. Also I never tested what voltage was stable for it and I didn't want it to run Prime 95 and in the 7h 56min mark have it take a dump and be like....crap lemme up the voltage and try again. So I set it at 0.5v under the max Intel spec, 1.5V. It is probably way less. Who knows. I want to decrease temps even more so eventually I'll find the right voltage.

Right now its at 8x400=3.2 GHz, however the E2180 has a 10x max multiplier, so what I'm trying to do is simply see if I can push the multiplier up to 9 or even 10 (although almost guaranteed instability). Not that I really would notice and extra 400 or maybe 800 MHz but I'm just trying to get better at overclocking. I'm not too concerned about frying the chip, I just ordered a Q6700 but I just want to see how far this thing can go...I mean its a great deal beating out the E8500 clockspeed for 60 bucks! I'll try upping the northbridge voltage and VID and see if I can get stable.

FSB is not the problem but its like you are hitting the limit of the CPU itself.
June 28, 2008 4:06:06 AM

lol i think im more noob than him.... i understand RAM is "Dual Pumped" and CPU is "Quad Pumped"....therefore, the FSB=400, so RAM=800 and CPU=1600 (400 multiplied by four because its quad pumped). SO, my question is, what does this 1600MHz mean? its obviously not clock speed as the CPU clock is 3.2 as he stated... so what exactly does having a 1600MHZ... SOMETHING mean? fairly confusing topic lol.

v3nom dont come in and ruin other people's thread.lol

the CPU is communicate through the FSB to the whole system include the RAM.

so cpu at 3.2Ghz 400x8 FSB1600 Ram@800

CPU 400X8=FSB400(QDR)1600=RAM 400(2cycle/clock)800

get it now?

Hope you have a fire extinguisher close by. I like your style dude. People say they doubt you can push it to 3.6ghz so you're like f it I'm going for 4GHz.
June 28, 2008 11:19:23 PM

Well, see what happens, I doubt it will be able to overclock that far.
June 29, 2008 2:27:58 AM

im truly in doubt as well. maybe i should just say you cant get 4Ghz. wanna bet?

FSB1600 which is 400 quad pumped which runs 1:1 with DDR2 800.

Sorry about that, I know you were trying to prevent a hijack but I thought I would enlighten the youngster.

NO!NO!NO!

i mean to the youngster you try to explain, which i did as well!no to you :)  its all cool!
