help overclocking i5-2500k

im being told elsewhere that the voltage must be incorrect as its impossible to run at 4.4Ghz on 1.056v... yet HWmonitor reports same as CPU-Z

also

what do i change in BIOS to change th voltage to 1.3v as a test?

these are the options I have under CPU
DVID
QPI/FTT
SYSTEM AGENT
PCH CORE
CPU PLL

Not by any means as it’s too early too tell.

Having said that 1.056V @ 4GHz seemed plausible – but the fact that the voltage read exactly the same for 4.4GHz may suggest that the app (CPUz Snadge?) is having a problem reading the voltage correctly.

But, it’s certainly within the realms of possibility of getting a sub 1.2V @ 4.4GHz (Look at my sig).

However, I couldn’t get to boot below 1.16V @ 4.4GHz – but I know of another member who was stable at 4.4GHz @ 1.18V.

D'oh - i should have refreshed the page when i got back.

Read above post - i'll and i'll d/l your manual...
 
thanks for the help plec i appreciate it

in BIOS main page Vcore is 1.284
there is no obvious setting for Vcore to change it - there is DVID Dynamic Vcore but its ion AUTO and you decrease or increase it in small amounts and default is 0.00
 
You need to enable 'Load-Line Calibration' - this should then give you access to the vCore setting - then set the vCore to what you want.

Reading your manual it looks as though CPUz is reading the QPi/Vtt voltage that or the PCH Core - as these are both static at 1.050V.
 
ok changing anything doesnt reveal the Vcore - these boards are new and probs dont have them, I did increase the VDIM by 0.030 and it did go up from 1.272 (4Ghz) to 1.296 flicking between 1.308 - i changed back to auto and its back to 1.284 (4.4Ghz)

it seems on this board it calibrates everything itself, the LoadLine Calibration says
enabled = improve vdroop directly
disabled = follow intel spec
auto

now when i had it on enabled the voltage was slightly higher at 1.308, i set at AUTO and it was 1.284, so this leads me to think AUTO is DISABLED (Follow Intel Spec)

is 1.284 alright for 4.4Ghz?

the next problem i have is whenever i change any BIOS settings the realtek LAN driver is faulty and needs to be re-installed? when i boot into windows it fails to connect then takes a further 64 seconds connecting (Identifying...) then it connects... I have to reinstall the driver fresh to get it back to staring in 2 seconds once desktop is loaded... gee, i wish i got the MSI board now.. so much for Gigabyte being reliable!!

i updated BIOS to F4d (it says f4c in my bios) and still no vCore

however I re-sit the HSF with arctic5 but this time a small pea lump in middle and temps have dropped quite a bit - it did look like a little bit to much on last time.. Prime95 @ 4.4Ghz hit a MAX of 68'c ... which is a lot better than the 74'c previously... tray icon says 58'c right now running prime95 after 10mins

is that better? (gellid cooler, arctic5 silver paste...no case fans)

Those temps are great - you can breathe easy.

I've posted posted in your other thread but it is the 'dynamic vCore' (DVID) that adjusts the vCore - it can either add or subtract volts from your existing vCore voltage (offset).

Have you tried experimenting with 'dynamic vCore' setting (DVID) since resetting the CMOS (after your BIOS flash)?
 
thanks for your continued support

for now my primary objective is to get this LAN working - its playing up still even after BIOS update... Gigabyte are useless!! i emailed them yesterday and still no reply, they have rushed out BETA updates on most boards but this doesnt fix my issue - i HAVE to get it fixed before sunday...no ifs or buts.. otherwise we are screwed if it turns out to be a dodgy board cos my dad cant replace it or anything like that, he lives up in the willy nillys of Scotland and are Gigabyte going to pay for someone to replace it (if he can find someone?) this is my problem...on top of that I have 3 other PC's here im trying to fix and have a website i need to be cracking on with to get finished before sunday but not gunna happen now - stress - stress - stress!!!

the bios does not report TWO bios's either (BACKUP/MAIN)

No worries.

Could you explain your LAN problem in more detail.

I had a socket 775 Gigabyte MB and it too had its foibles. If i allowed windows update to go anywhere near it (via optional downloads) the LAN would develop a conflict and become unstable until i ran system restore.
