is there something that changes the multiplier automatically?

 

It seems windows starts with the 20x multi and the after pit and 3dmark test it scales back to 12x multi.....

 

Thats where my test seems to slow down in is the CPU...

heres the lastest test...top 1% or better for everything but internet :P

 

new 3dmark with o/cing

Make certain that the vcore and QPI are within .5v...........

still getting used to this but i keep hitting a wall at 4.0+ and stable...

 

4.0 it stable prime95 for 20 minutes+

 

i now have to figure out how to up the clock and get it to boot correctly...and stabilize it...i know this chip can hit 4.3+ but i cant seem to find the right settings...it always freezes up on the main boot screen...

 

well its all trial and error... :cr@sh:

I need some tips here....on overclocking over 4.0ghz

 

it seems i hit a snag on start up when trying to go over 4ghz

I have my dram settings currently @ 7-7-7-20 up to 4ghz.

when i go over 4ghz i try 8-8-8-20 or 24 and still no boot

 

i change my voltages to about 1.32-1.34 when going over 4ghz...still no boot...

 

I dont know whats doing on...or if i am missing a setting...

ok i don't know if these terms are the same for your bios and cpu(can't remember which one you have)

 

but here's a couple of things you need to know and remember when overclocking an i7.

 

1:- everything is a multi of the bclk

 

2:- uncore must be set to 2 times the memory speed at least.

 

not sure of your memory speed so to start with set it to 6 times 200 = 1200 mhz

 

set the uncore to 2600 mhz

 

set cpu to 20x

 

set qpi to lowest multi think that's 32x

 

leave all voltage settings at auto except the ram, set this to 1.64v and set the cpu voltage to 1.275v

 

now try and boot if it boots and is not stable increase the cpu voltage a notch, keep repeating this until it's stable.

 

when it's stable you can increase your memory speed if it becomes unstable you know now it's because of the memory so might need some tweaks on settings.

 

:b33r:

 

edit:- if you still can't get it stable at 20x200 you might need to manually adjust the qpi/dram voltage to around the 1.4v mark

set everything to auto...

 

multi @ 20

BCLK @ 210

CPU volt @ upto 1.35v

Dram timings on auto

 

ram is rated at 1600...

 

so it set it to 16xx and also underclocked @ 12xx

 

uncore is at 2x (minimum setting)

 

i wont get past the start up screen so i can access bios...it freezes instantly so i cant hit DEL or tab...

 

 

once i try 205 or 210 BCLK and save/exit bios.....it freezes instantly.

 

@ 200bclk its perfect and stable...anything over that point wont even boot correctly...so i dont know what it is...

Then you need more vcore then what you have been giving it. Only thing that has really changed is the cpu.

 

i dont know...anytime i try past 200.... no matter the volts it wont boot...

 

its kinda crazy...

Do you have Everest?

 

If you do, load up the stress test and have it showing the core temps and voltages, take a screen shot and post it.

 

yea...i pulled the temps off there...i think im going to reseat this cpu....ill be back with you guys in a little while..

try a lower multi something like 15x for the cpu for higher bclk than 200, if it still doesn't post i'd think it's definitely a memory/uncore setting somewhere that needs adjusting.

 

 

:b33r:

 

edit:- your on air so i'd think those temps are about right. :tup:

 

with the standard heatsink and fan my temps were well over 90c at 100% load even with a mid overclock like 3.6ghz

hmmm...yea i tried that...15x215...still no boot...

 

 

i switch something...and i think the voltages will suprise you... :P:shifty:...

 

Currently stress testing it....will post after 10+ minutes of stress testing...

I got 2 cpu's to play around with...

 

and it seems the second one performs a whole hell of a lot better.

 

now its a matter of testing to find out how to get myself over the 200bclk....

 

still on factory timings @ 7-7-7-20
