Do I actually need to get a 1000w PSU in order to overclock great then 3.5 GHz. Currently I am using a 850w Corsair HX. I have tried to get past 3.5 GHz but then it won't post?





Thanks

850W Corsair Power is absolutly enough.

Try more Vcore, more VTT and .. why ur PCH is so high???
My 860 is working at 4 GHz with 1.04V PCH. (PCH = Southbridge)

Hold on, I heard it was bad to go past 1.20 on the VTT, is that still true? I will give it more VCore probably 1.35000.

my 860 is degrading I think or the newer bios just arent as good for ocing as the earlier ones. it used to run these settings exactly as posted on the first page but with less vtt now it needs more vcore like 1.36v im aiming for less vtt though so been using around 1.325v. VTT=more heat and that blows

well Peeps I just got to say thanks for all the info and help from reading all your sugestions, and all your screen shots. Withou any of this i would have taken a year to get a nice overclock 176x22 which gives me 3873.2mhz  obviously with with turbo boost enabled. she past all of hyper pi no problem now all thats left is to prime 95 it just to see how stable it will stay. I got to work tomorrow so it may take a day or 2 to post a couple of no BS screenshots. my system is just a week old and i think i would have narrowed down this oc alot faster (due to the overclocking guide) But OCZ REAPER HPC 8 gigs was troubling me, turns out the 1.65 setting only gives it 1.63 so i bumped it up to 1.66 which gives me a steady 1.65 in windows and boom hyper pi done. I love My Classified 200 its going to be real tough to beat this board and no need to py the extra cash for a better processor when this one clocks into an Extream Processor for a quarter of the cost........oh yeah this is my first build and first Overclocked so I am a lil tweaked myself. I could not have done it without These forms and Jacobs OC Guide......

Thanks Jacob And Thanks To Everyone Who Posted A Result.

someone has an idea for my problem?

@overclocking101: 
what's up with the VTT and the CPU PWM Frequency?

BTW: your signature said, that ur 860 is at 4.4. with 1.3???? ;)
Turbo.. or? 

And.. if 22x200 won't work for you, try 210x21 ;)

Has anyone with an i5-750 with the P-55 Sli and 8G's or Ram
Pulled a 4.0 Stable 24/7?

How high do you think it is safe to go with the following config:
i7 860 (stock cooling, for now)
P55 SLI
Corsair XMS3 4GB (2 x 2GB) DDR3 1600 (Model CMX4GX3M2A1600C9)
EVGA 8800GT
WD Caviar Black 1TB
Corsair 650TX
HAF 922 (stock fans, hopefully good cable management) 
DVD Burner

Think i could hit 3.5GHz Stable? (with Turbo Boost, HyperThreading, and Vdroop on) 
(ambient room temp is ~25C)

hahah... ok, thanks for the advice!

With the stock cooler, i got it to 3.35ghz at a very low voltage, i think 1.1125v core and the other ones are low too. It hits 4ghz on turbo. 

picking up a new cooler soon

sorry if this is a super noob question my memory is
Mushkin PC3-12800 DDR3 4GB Blackline Black FrostByte Low-Voltage 2x2GB Kit - CL 7-8-7-20, 1.65 Volts
what will my memory configuration be, im new to this so i can follow something but i dont understand what im doing really

I really don't understand what I am missing, frustrating the hell out of me. I really just tried bumping the VCore and the Clock to get to 4.0 GHz, but I keep getting Watchdog after 3.6 GHz and then I had to CMOS Reset. I am back at 3.5 Ghz, but now my OS loads slower then before the CMOS Reset.







Could someone give me some good tips, I have tried lowering my PCH to 1.04v but it only got to 1.50? I am not sure which PCH is being referred to.

Just someone give me some tips, at least to get my OS booting faster with the OC of 3.5 GHz.

good luck there mate, my 15k 'gaming' rig is now a brand new regular email pc,  yes i should of just bought a pre made machine i know, catch 22 -  on but not able to perform high end tasks, or a pile of cold plastic in a box? yeah basically i wasted my money and time

who can i overclock a p55 v? any chance to try another bios?

I have ordered my FTW200 Motherboard ,which should be arriving any day ,and I am very happy I chose to go with EVGA . I have currently been using an Intel DP55KG ,and have been very disappointed with my OC . My max speed ,stable has been 3.5 Ghz on my 860 using the CM Hyper 212 in  push/pull mode  to keep things cool .This was my first build ,so I've learned I will never buy an Intel MB again!!
