cant overclock cpu with XPS 630i from bios (Q9300)

i have the dumbest probem ever with this pc. dell has said that you could overclock this pc in the bios, ok so i got into the bios and change the fsb(QDR) from 1333 to 1440mhz to get a cpu speed of 2.7GHz (the Q9300 is 2.5GHz stock). ok so i change that and unink the memory and save and exit. but everytime i get no post, i get nothing so i have to boot my pc 3 times to reset the bios/cmos and change back to 1333mhz. no i didnt change any of the voltage settings and im getting to why next. after resetting the bios, i load vista (32-bit) premium and open the nvidia control panel. there i go to the cpu tab and change the fsb from 333 to 360 upping by 5 mhz at a time. while this is happening im not changing the voltage its stock at 1.238v and i can get to a fsb of 360mhz (2.7GHz) before it freezes (without changing voltages, after 2.7GHz i have to up them) . so i save that and make it load when windows starts and it works. why is it i can oc my cpu in the nvidia control panel but not the bios? its a little frustrating. now i would like to get this cpu to 3.0GHz. the highest i took it was to 2.8GHz but then i think i smelled smoke (i probably set voltages to high) so i returned them to the 2.7GHz settings. i noticed the motherboard in this pc has a highest cpu fsb of 1333mhz, so is the actual mobo holding me back form being able to oc in the bios? the max supported for the 650i sli is 1333. would i need to upgrade the mobo to be able to overclock in the bios? but if thats true then why is it able to overclock with the software? any explination to this and/or help would be greatly appreciated.

Make sure you hit enter after a change then F10 and enter again when you are all done. Make sure speedstep and C1E are disabled also and that memory is set to optimal. I've got my E8400 clocked 600 MHZ over and I think thats all I did. Hope you get it going.

you definitely can go higher than 1333 FSB, I'm at 1400 now.  Like mentioned before make sure you are actually saving the settings.  Also, if you predefined nvidia profiles, make sure u update them with you latest bios settings, this can cause conflicts if you don't.  Also, like the previous poster mentioned, the yorkfields don't seem to overclock too well, not sure if it is the chip or the mobo.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

ok i really dont know "what" is going on. i cant even change the fsb in the bios from 1333 to 1334 and get a post screen. i up it one little mhz and get no post, this is busha, i disabled c1e and speedstep and i tried using f10 to save the settings but i still get no post. could someone with a xps 630i please explain how to do this cause this is getting old real fast. id like to get to 2.8GHz to 3.0GHz but my pc doesnt seem to like me very much. so any help would be great thanks in advance.

read shdbcamping's post - he quotes that your processor is not overclockable in the 630 via the BIOS....

 

See this thread (page 3).

packerFan07,

Thanks as I was wondering if I was the only one that could read my postsSmiley Surprised . I'm just passing along info from Chris_M to save some people some headache 'til this all gets sorted out.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

yeah thanks for the links and info/help guys. im angered at the fact this pc was sold as "overclockable" but theres always a catch somewhere isnt there. i can get a 10% oc by using nvidia control panel and go from 2.5GHz to 2.7GHz on stock volts. i tried 2.8GHz with changing volts but it just freezes, so at least i did get what i could. i hope they fix this issue with the yorkfields so we can get that oc goodness too.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

try this,

 

unlink memory and fsb.  Set the fsb to whatever 1400 or what not leave memory alone.  Now go into the voltage settings and apply a manual voltage to the CPU and FSB leaving the mem and chipset voltage to auto.

Add .05 to what ever the default was to start.  And see if you post.  

 

I know i couldn't post if i didn't have both the CPU and FSB voltage set to manual values.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

ill try but i dont think the q9300 can be oc'ed in the bios. i got it oc'ed in NCP and it runs fine. ill try and post back with the result.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

no luck with the bios again, ohh well. theres always a catch to everything, some are burried deep inside though. but the nvidia control panel handles overclocking the cpu well so ill stick with using that. or that could be the irony of this whole ordeal. they state that you can overclock this pc but with the "non-overclockable yorkfields" maybe you just have to use the nvidia control panel. so to anyone who wishes to oc your yorkfield, use nvidia control panel and thanks to all who helped in this post. oh and by btw what is nforce mcp core stand for/mean under the motherboard tab under voltages? do i need to change those voltages too when i oc? and if i change the cpu voltage by ".05v" should i change those by .05 also meaning do they have go up symmetrically? any explaination on that would be very helpful and appreciated.

Re: cant overclock cpu with XPS 630i from bios (Q9300)

read this, it should help you get a better understanding of ocing.  Though it says 680 and the 700 series board it applies to most mobos as well.  This guide just has more settings.  The one nice thing about the 630 is that it is for newbies to OCing.  Since i'm not a hardcore gamer the 630 fits the bill for me.

 

Anyways, when adjusting voltages of one component you don't have to adjust the others unless needed.

 

Usually, you set the FSB and see if you post if not then try upping the CPU voltage a little till you do post.

Each time a successful launch of windows run stress test software like, Prime95 or OCCT for 2+ hours.

 

Don't go over the recommended CPU voltage though.  Once you get close to that number start upping the other voltages and see if you can get stable.

 

For me i have a q6600 (only because i heard it overclocks real nicely, i've hit 3.2 from a 2.4 stock) and i have my voltages at 1.45.
