2 questions ocing my e7400 on a p45 neo3-fr

Question

Hey people, maybe someone can help...
So, i´ve been trying to learn about ocing and how PCs work in general. I´ve read tons of material: from intel´s datasheets and thermal specs, to fancy website´s guides, and I still can´t find answers to a couple of question I have. 
- The first one, ¿How much stress testing do you, the more experienced front, consider enough in order to label my system as ROCK-SOLID? ¿What percentage of stability would you give me if I ran prime95 (blend mode) for 10 hours + 50 Intel´s BurnTest passes (maximum) + 10 hours OCCT linkpacked in 64bit mode?
- From this forum´s guide, if the FSB is defined as the speed between CPU and RAM, ¿do I have to increase Vdimm if I increase the FSB, even if I manage to maitain the RAM´s speed by changing the FSB/RAM ratio? I mean, I have some Kingston Hyper-x PC-6400 @800Mhz4-4-4-12@2v (ratio 1:1.5) from a FSB@266Mhz and I raised my FSB up to 286Mhz (I know, I such a nub ,but the idea is to get to somewhere near 3.6Ghz=10.5x340FSB), but changed the FSB/RAM ratio to 1:1.25, lowering my RAM to 715mhz (in order to take it out of the equation), without touching Vdimm (or any voltage for that matter). ¿Should I raise Vdimm to achieve the same 800 original Mhz´s? Let´s say, if I pump FSB@300Mhz and set FSB/RAM ratio to 1:1.33? ¿[email protected]?     ...now that I wrote it down...that doesn´t sound right. Anyways, the question stands.
- Finally, Is there any information and how-they-work about those more complex options in BIOS? I mean things like "CPU/MCH´s drive clock" (skew I kinda of undestood), "enhance setting for dual channels", "Adjust PCI frequency to 37 or 40 Mhz",and  "PCI latency timer to 32, 43, 64, 96 or 128ms?
I´m already thankful for any feedback or redirectioning, and please excuse my bad english. Greetings.
My PC:
E7400 (2,8ghz, 3Mb, 1066FSB, 1.2675v) on a P45 Neo3-FR (PCB1.0, [email protected], [email protected] and [email protected]) with 4Gb=4x1Gb Kingston Hyper-X PC6400@800-4-4-4-12@2v (ratio 1:1.5), Soundblaster X-Fi Gamer, Zotac GTS250 1Gb, ThermalTake ToughPower 600 Watts PFC.
My first succesful run through the above detailed stress tests:
[email protected]=3003Mhz, RAM ratio 1:1.25 (715Mhz4-4-4-12@2v), same voltages, no c-state, no EIST, no dual-channel enhancement, no spread sprectrum, no execute disbit, no nothing.
I´ll be posting my progress towards the 3.6Ghz, but I´ll need help! 

Answer 1

hello again,
thanks again to hive, for both replies and the corrections she made to her first one (it was MCH instead of ICH, I knew that  ). Very nice person hive, thx.
...And since you are the only one taking interest, I have one more question, ¿Did you have to tweak clock driver and/or skew in BIOS to achieve +400FSB? ah! and ¿during the year in which you worked with [email protected], did your disks experience any corruption at all? Meaning in O.S. or media.
..And about the silly testing  : The thing is that I´ve heard and read a lot about stress testing, and there´s always this discussion about how much is enough, and finally (I guess) about the very definition of the word "stable". My conclusions are that it will all finally come to how much maniac-obsessive is there in you. There´s ppl that wants they rigs to be able to work for weeks under synthetic full-loads, and there´s ppl who don´t give a damn if it crashes every 3 days or so, or have to re-install XP every 3 months. Moreover, prime95´s txt´s says that if you don´t pass any of them test, you have a hardware problem, period. That´s emphatic enough to scare me. So I am gonna waste time in testing (risking that at the very end of the month it´s going to take me to find out the limits, I´ll look back and agree with you, in which case it´ll end up posted right here  ). I really go hysterical every time I loose 3D-Studio 18hours-long renders or do some pretty tough mission in GTA4 and it goes BSOD on me... those TFT old screens can really take a punch, I´ll tell you that But seriously, if you can just roll your eyes at me and then just tell how you got it stable at 4.2ghz and 1.38v (EIST?c-state? skewing?VTT? MCHv? enhancing? yadda-yadda..) I´ll be even more grateful that I already am.
Finally, regarding the temps, I have 2 thing in favor: Down here it is as much as 10, maybe 15°C cooler that up there, and E7000´s series have a 2°C threshold above E8000´s (74°C). Even further, I used my obsessions to seal tight the tower and manage the air-flow , so it sucks cool air from the low-front and expells it through the back-top end. I really worked on that and now if you drop a small piece of paper into the in-flow at the front, it gets sucked-in and expelled through the back really fast. Intel TestBurn hasn´t gone higher than 60°C at 3003Mhz/1.2675v.
Nice people be well.
