E8400 common voltages - Overclock.net

I have a P5E64 WS EVOLUTION and an E8400 E0 with mushkin 996600 ddr3 1600 at 7-7-6-18. I am wondering what are the common voltages for PLL NB etc. and what voltages will I need to change going to 3.6 and 4.0

I can get both 3.6 and 4.0 just fine I am having a random BSOD 124 code doing random things not stressing. I can pass all tests intel burn test etc. but it crashes randomly watching youtube etc.

My board has no vdroop whatsover I dont know if the previous owner did a pencil mod or what but it never moves at all in cpu-z.

This is what I have at 400x9
CPU 1.325 (1.304cpu-z)
NB 1.31

and at 445x9 I have:
CPU 1.4125
NB 1.41

From there I did set the fsb termination to 1.25 and the CPU PLL to 1.56 I believe but at this point I was kind of guessing so I am asking here basically when and what to change the CPU PLL and FSB term and NB voltages.

Edit: There are a ton of settings there. Mine are listed there somewhere or you can hit the link in my sig for settings.

Ok thanks for that I guess I will geback to 4.05ghz and post a cpu-z so I have it when I join. I am trying to master it at 3.6 so I can get the idea of CPU PLL, FSB termination, NB, etc. when to use them what they are for exactly etc. What are the neighborhoods for those voltages etc.

I am working on it Its just the random bsod I was having I thouoght was related to the OC when I know now it dosent so I was artificially bumping vcore etc and those voltages so I am out of reference right now and have to start back over. For instance it seems I need at least 1.31v to boot at 3.6 but I can leave everythign else at auto. at 4.0 I need 1.4 to stay stable I have a vid of 1.25 by the way.

What is the code that the blue screen says? Like IRQ_L or something like that.

ghost2501 · 07-02-09

I dont actual get a blue screen it always freezes the screen on windows. When I reboot I get a crash dump that says blue screen 124 adn I have the crash dumps saved allthough all I can get out of them is it says hardware error. I used the debug software to look at the crashdump.

I swithced from an ide dvd to a sata and it still happened, then I unintstalled the sound drivers and it still happened. It happened twice when I was downloading on utorrent so at this point it is trully random the only time it dosent happen is durring stress testing etc.

I am now running 445x9 and I have 1.4125 (1.384 CPU-Z)
NB 1.41
fsb ter 1.26
CPU PLL 1.56

1.9v memory and I have them at 8-8-8-24 1780 right now instead of 1600 at 7-7-6-18

I am stable right now and I plan on trying to watch some old LEXX episodes Via my dvd drive so I can try to replicate it.

I only saw the bluescreen once but I cant remember what it said. I am pretty sure it didnt say the standard irq less than or equal etc. But I am watching next time for sure.

One more question.... when overclocking and the pc freezes instead of bsod or rebooting is that asign a certain voltage needs iincreased usually etc or not?

Well the only thing I see is your fsb term seems low. Might try to bump it a little and see how it go's. Sorry I'm not more help.

ghost2501 · 07-03-09

what would you say is a good fst? 1.31? Its seeming stable now I am gonna reinstall windows xp maybe to see whats what but only if I can get it to crash again and its not. Boy I like these muskins though running them at 1.86v and 1780 and they are not getting hot at all..

Try 1.28 or 1.29

I upped the voltages but I just got the problem again today.

Here is how it goes The PC always freezes, no actual BSOD no restart etc. I have never had any probs stress testing, memtest 10 passes multiple times, I did a HD scan using spinrite etc.

I always geta a 124 bsod code. Can anyone check out my minidumps as I cant get heads or tails from it. I have a laser engraver/cutting machine and if someone can help me get thsi fixed I will hook them up with some custom stuff.

This is starting to sound more like a software problem. How many processes so you have running and which ones do you not need? Also if you have not already run some virus scans and defrag.
