i7-2700k OC 4.5GHz help - Page 7

post #61 of 71
Do you have the power saving features enabled? EIST, C1E, C3 and C6 in the BIOS? If not that will keep the idle temps high. But idle temps are really nothing to worry about since they depend so much on the ambient temps. 35C is fine. I think that's about what my chip idles at.

Do you mean that I only need vccio at 1.07v? smile.gif Is there any negative sides using bus speed at 103 MHz instad of 100? This was default when I used Asus optimal mode on my mobo, which was at 4.4GHz, then I just added 1 on multiplier to get it to 4.5GHz smile.gif

Set the BCLK to 100 MHz, LLC to High or Ultra High, offset to manual and below 1.40 V. The VCCIO voltage is alright.

i will try to stable at 1.5 then, the TCase of the 2700k is 72.6°, that's why i don't want to cross it, even in prime95.
By the way, gamming (Crysis 3 - Everything in Very High, does not lag and stays around 57°) should be fine, but want to get more from the SLI

thnx

I really wouldn't let it go above 75°C. Have you considered a better CPU cooler or is it caused by high room temperatures?

A CPU PLL voltage of 1.5-1.7 V should be absolutely fine.

Guys ive been making some changes:

1 turned the fan of the cpu towards the biggest fan in the case(top of it)
2 changed the grease for the tg1 previously mentioned
3 change to offset mode (that was my greatest concern its offsetted to -0.9, getting 1.27 vcore
4 increased the multi by 45 (x100)
5 decreased two clicks from 1.5 to 1.45 something on pll voltage (it decreases temps for me)
6 iddle temps: 30c startup bios, 35 for system idle (5 minutes after startup)
7 ran prime test for 30 mins stable (im running a vernight test to check the stability)
8 max temps on 68 in CoreTemp and 69 in hmcpuid

Well, it seemed fine for my expectation on that cooler, but dunno if its really ok

let the expecialists reply. . .

By the way
room temp of 22c
and crysis 3 and fsx both at extreme max options ran very well with crysis 3 without any lag and fsx at 20 fps, b

After some Time in Intel Burn Test, a message of unstability appears (NBT one).

On Prime 95 it Went OK!, stable with max temps of 71° at 2.8v

at Intel Burn Text on Extreme 16GB Ram Usage it crashed (Not Blue Screens or anything, but NBT message) max Temps 74° at 2.8v

ITB should stress more than Prime 95?

thanks

2.8 V?

The CPU really shouldn't go above 70°C at only 1.27 V. You should consider a better CPU cooler. There are cheap but efficient coolers such as the Hyper 212 EVO.

Sorry, t've missyped i think. it ran at 2.9 not 2.7.

but still!

at the moment i cant go with another heatsink.
post #68 of 71
2.9v? no. do you mean 1.29v? thats what villain was basically asking.
and i dont understand what NBT message is.

Ok
you all got me
got a h100
temps are cooler
4.5x at 1.31v at 69c full load temps in prime95 for 30 min on blend
test and 34 at idle
i will keep pushing down voltages to se if i can get coolet than that and stable

room temps at 21

I will keep running the prime 95 for some hrs and see if it is stable stil

Hey Guys,

FInished my 11 hrs test in Prime95 and my overclock is prety stable.

dunno if i can go any lower with the voltages, bt i will try.

the h100 isvery good to keep all cool... smile.gif

4.5x at 1.31v at 69c full load temps in prime95 for 30 min on blend
test and 34 at idle
what you guys think?
