voltage question

[qwertylives]

hi,im trying to overclock my i7 930 and after reading through various guides i decided to try and build to roughly 4.0mhz in small steps,i used cpuid to note some temps,volts ect running standard spec b4 i started.first off i have just done my 1st overclock to 3.4mhz and ive been running prime95 for around 2hrs(still running) to check stability,this is where i need help,when i noticed my volts running standard i was using roughly 1.216-1.224v(@2.8mhz),but since overclocking my volts seem to be using less (currently pulling 1.168 @ 3.4hmhz) i was under the impression you used more volts as your overclock increases?sorry if its a noob question but as im an oc virgin i just wanna make sure everything is right,thanks.

posted a screenie if that makes things clearer:

thanks for the advice,do you think its best setting vcore back to auto then before i try to increase anymore?or just crack on ?im sure i set my vcore to 1.2665 although im not 100% without going back into the bios.

thanks a lot,im done for tonight but will continue to test tomorrow,guess ill post then,thanks once again!
spec is:

intel i7 930 do + zelman extreme cpu cooler with home made mod for push n pull

hi just another question,i have managed to get a stable 4ghz out of her now,however i tried to up the base clock to 200 to try and see if i could run 4.2 (im running a x21 multi) but my dram frequancy changed,atm running 4ghz its on 1588(or similar forgot exactly) but when i increase the base clock i dont get this option anymore,just 1253(not exact) and 1603,i didnt want to set it to 1603 as thats over my 1600mhz ram so i went with the 1253 setting,loaded up windows,ran prime and it froze instantly,is it safe to try the 1603hz value for my dram or have i missed something else? cheers and sorry if that doesnt explain itself properly.

thanks bif,slowly but surely getting there,whats the max temps you recommend running under 100% load?i was thinking i didnt want to go above say 85degrees,but im sure i read somewhere some guy say 100degrees was safe while running prime95 on an i7,just curious as to where you stand on this as ill just listen to what u recommend and aim for no higher than that.

just had a crash trying 4.2,got this message on a blue screen amongst other text.

*A clock interrupt was not received by the secondery processor within the allocated time interval*,any ideas what casues this?ill post a my settings(used for the 4.2 attempt)so you can see if anything is standing out as a fail.

cpu volts 1.31875
qpi/dram 1.20000
cpu pll voltage 1.88
ioh 1.20
ich 1.20
dram 1.66
LLC enabled
cpu spread spectrum disbaled
turbo disabled
and finally using a bclk of 200 using a x21 multi=4200

sorry for being noob.

 

[qwertylives]

thanks for the rapid responce bud,i'll jump on that now

 

[qwertylives]

howd you get your dram bus to 1.65 lol? 1.64-1.66 is all i see and i have the same mobo,im currently running 1.66.and ill give those settings a try as ive been testing various settings and just cant get 4.2 stable atm

 

[qwertylives]

cheers for the advice,currently running prime @ 4.2,touch wood all's good so far like 30mins in,temps a tad on the high side with the hottest core maxing at 98 and running mid 90s stable(hottest core max=98,coolest core max=90degrees)if prime survives for 90mins ill try dropping my voltage to reduce those high temps.

 

[qwertylives]

yea i hope i have some headroom as my vcore is set to 1.4 atm,just want a stable clock,(albeit with high temps !doh!) before i start reducing the volts.almost 1hr in still running without fault.

EDIT: done 1hr+ on prime,gonna try getting those volts+temps down now slowly but surely.

 

[qwertylives]

after a lil fiddling im managing to run 4.1 at decent temps,been running prime for 2hrs so far without problems,ima leave this running overnight and if all is good in the morning ill try to hit the magic 4.2.

agreed paul that the zelman extreme isnt what id choose if i was spending £50 of my own money,but it was off a pal who purchased it for his i5,it was to big for his case unless he left a side panel off lol,so i got for the bargain price of £10 also modded it with another 120mm working in push n pull with the existing fan,it'll do for now until i upgrade to the 2nd 480 and some water cooling when i can afford it around xmas time
and thanks for the advice paul,i have indeed decided to stay at 4.1 for now as its all i'll need,i'll try pushing on further with water in a few months,trouble is all this tweaking gets addictive
