I've got an E2220 that I have stable at 3.0(not very far since it starts at 2.4.....) 333x9 at 1.4125vcore but to get it to 3.33 333x10, I have to up the voltage all the way to 1.53 or above to get it orthos stable. I have a p5k-se/epu mb (not the greatest, I know, but it'll at least take more than 400 fsb) and I'm running my memory at stock 800 mhz and timings. Is it worth the ridiculous high voltage for that? and does anyone have any tips or suggestions? I'm trying to get the most out of this chip until nehalem comes out so i can get a penryn quad for much cheaper(i'm hoping prices on the 775s will come down a pinch.)

hmm. Your voltz seem really high. I get 3ghz on my e2140 with only 1.3375v. Try fiddling with the other voltages to see if it helps with stability. If it came down to it, and it really took 1.53v to get 3.3ghz, i'd say forget it.

I thought that seemed really high, I looked at an overclock chart for e2xxx series and voltage for around 3.3 to 3.6 seemed to be much lower than what I need to hit 3.0. but none of those were e2220's so they may just be bad ocers, plus to add to that, this chip won't post above 335fsb(****ed me off....i think this chip is just garbage) and I think the mobos ok as it's advertised at being able to run 400fsb stock. there are no NB voltage settings and it lacks many settings that i've heard referece to though, which makes me think I got screwed because I bought this before I learned about or planned on overclocking.......boo. Haha, I should find a 2160 and take it up to like 3.3 or 3.6, i'd be better off.

oh btw, my temps are still great, well below acceptable, staying below 50-55 even at that ridiculous 1.55vcore

What are you using to monitor the temps??

Also, the NB voltage may be called MCH, MCH allows the higher FSB speeds.

I am using core temp/real temp/speedfan(they all get same values) everest gets that as well, but i don't use it often. and nope, nothing like mch in bios, but i seem to be limited more by the cpu than mobo, as i said, it wont even post past 335 haha. I can get you a screenie if you'd like to see the temps. Oh, and i'm using a zalman 9500. and i'm giving bios voltages, not in cpuz voltage readings

In that case you might have some room if you have a lot of vdrop. What does CPU-Z say your vcore is under P95 small fft load?

[erricrice]

ooo, right cause cpuz is showing the voltage that's actually going through the cpu. well, right now i'm running at 3.0 ghz, and the bios is 1.4125. Idling in windows i get about 1.368 and small ffts with orthos i get 1.320, so my vdrop is .0925. wow, i didn't realize that it was so much. so if i were to set the voltage in bios even as high as 1.55, my windows idle would be 1.5055 and load would be 1.4575. that is a bad amount of vdroop isnt it?

[BranNutz]

I have been getting up to .1 worth of vdroop myself so it's alot but not uncommon.

[jason4207]

Good rule of thumb is to keep vcore under P95 load under 1.365v (maybe 1.4v), and just adjust the BIOS as necessary until you get that.

Vdrop and vdroop, are not bad per se, but they can limit your OCability to some extent.


Edit: just realized you have a 65nm CPU. You can push more juice through them. Maybe 1.55v max on air under load, but if you can keep it at or below 1.5v that would be better. You can also crank the voltage on FSB Term (vTT), and the NB if needed, but it sounds like you don't have a lot of options in your BIOS.

[erricrice]

so that would be 1.5 p95 under load, or 1.5 windows idle? and yes, my bios seem to be quite limited, no vtt or nb voltage at all =((((


o nevermind looks like i'm dyslexic, you said under load
thanks, and it looks like i've got quite a bit of room to work with(since my vdrop is almost .1)
