please help with this over clock i feel like an absolute noob :s

right, all reverted to optimal defaults. disabled EIST, C1E, and unchecked any kind of turbo mode or anything. the memory seems to have gone from profile 1 to defaults and now my memory is not at 1866 but instead, its at 1066, that right ? :s

gunna restart and enable ht as i dont think it should be disabled, al make sure multi and blk is actually at default then ill post a screenie of temps, right now theyre running at around 35-39. c
 
personally

if i were you

i would reset to bios defaults

load your XMP profile

and run memtest to make sure your memory is working properly

there is no reason whatsoever that those settings shouldnt be working

here's my temps, no idea why its not at stock 3.06 even though ive cleared CMOS.

disabled EIST, c1e and any turbo modes applied. kept ht enabled.

Everything is at stock, including the memory. Which is a good starting point. Now, just up the BCLK 5Mhz at a time, and run intel burn test like I suggested. Find the clock at which the burn test first fails.

Reboot in this clockspeed, and post screenshots of CPU-z main and memory tabs.

Also - temperatures at idle don't tell you much of anything. You need to report the max temps during the intel burn test.

But clearly they aren't. Whether that's due to a poor component, or due to user error, he has tried this and it isn't working for him. So the next approach is to go back to basics: Start from stock and incrementally increase clocks until failure. Then adjust settings/multis/voltages to remove limitations until either safe temperature maximums or safe voltage maximums are reached.

managed to get it to a stable 3.5ghz with no voltage changes what so ever just with blk, these are temps, im quite happy with this, are these temps okay for these clock speeds ? think my memories set to 1860.

i've found with my ud7 i need a small bump in qpi pll - only to 1.14, but that helped massively with stability

ive changed my qpi pll to 1.14, i dont know if theres actually any difference but the system seems a lot more stable, booted up nearly 2x as fast and isnt sluggish anymore. could you explain what the qpi pll does ?
 
pll = phase locked loop, and is essentially the clock generator. so for the qpi, it has it's own clock generator the same way as the cpu does. now, increasing the voltage of this allows it to 'lock in' to the waveform (usually generated by a crystal) and amplify it, which makes it a cleaner waveform. What this does it allow the less jitter/skewing of the clock pulse, thus making it more stable (which is caused by everything staying in sync better).

been a while since i was at uni now, so it's not completely fresh in my head, but that's the general gist :)
 
so what do i do now ? surely if i was to set the blk any higher id start having problems, what sort of voltahe should i used after 3.6ghz ? load line calibration enabled ? and qpi voltage i need to change, should i change ram voltage ?
 
bclk increases will cause cpu speed to increase obviously, so more vcore and more qpi voltage maybe needed. as you start getting to higher bclks, you may need a small increase in qpi pll as well, but see how it is with just a boost in vcore and qpi voltage.

for 4GHz, i'm having to use 1.33vcore and 1.31qpi voltage, but this is without LLC
