4.4Ghz Core i7 960 On Water, Need your help please

[iNoXiouZ]

Hello!

TTL has given me the overclocking bug

I'm trying to reach 4.4Ghz stable (Prime stable) I'm currently at 4.05Ghz my settings are as follows:

Muli = 25 (24 + Turbo)

Bus Speed = 161Mhz

Vcore = 1.300000V (BIOS) Idle = 1.28V Load = 1.248V

QPI = 1.335V

IOH Core = 1.20V

Memory Freq = 1610Mhz

CAS 8-8-8-24 90 1T

PLL = 1.880V

DRAM = 1.66V

Max Temp 62CThis is stbale and my current 24/7 OC

My PC Specs are:

Core i7 960

Gigabyte GA-EX58-UD5

3 x 2GB Corsair Dominator 1600Mhz CL8

2 x GTX570 Beast Ed.

Custom Water

Modified SilverStone TJ07

NZXT 1000W Hale 90

80GB OCZ Vertex 2

1TB Sammy Spinpoint F3

And now the settings I've tried for 4.4Ghz (Well 4.425Ghz)

Multi = 25 (24 + Turbo)

Bus Speed = 177

Vcore = 1.525000V (BIOS) 1.502V Idle 1.488V Load

QPI = 1.375V

IOH Core - 1.26V

Memory Freq = 1416Mhz

CAS = 8-8-8--24 90 1T

PPL = 1.880V

DRAM = 1.66V

Stable for a few minutes Prime95 Blend

Max Temp 75C

Not to bothered about the life of the chip, just enjoy overclocking/benching

So guys what I'm I missing or is it just a case of more voltage?

Thanks for reading.

around this time TTL would say 200 fsb and up the multi and vcore til ya hit it lol I think 1.52 volts is gonna hurt after awhile lol

If you have a good chip it may,be possible to reach 4.4ghz prime-stable on water.

I like this thread,its one of the most visited in this forum.

Thanks guys, I'll get the blck to 200, I know it can do 221 blck.

I read a review over at xtremesystems on overclocking core i7's and it said that aslong as your temps are safe (this guy that wrote the review said that Intel says 100C is safe so thats what he calls safe)that voltage didn't matter...

It sounds like a load of *^*£ to me, I'm thinking 1.525V is high, but whats too high?

Anywho onto the 200blck

I wouldnt go higher than 1.43v and 70c temps.

200bclk is the way to go and change cpu-speed on multiplier.

Read the thread i posted thoroughly,follow the steps taken and you will learn to oc an i7-9xx properly.Its all explained how to and why.

But do ask,if you need some help.In a day or two you should have at least 4.0ghz prime-stable.

There is only one way,its the hard way,to learn oc`ing an i7-9xx cpu.

Thanks for the link man, I've read through the thread and its very informative, however the OP is limited to his temps and so isnt really pushing his overclock.

4Ghz isnt an issue, neither is 4.2Ghz, however 4.4Ghz is proving to be differcult.

Now priming at 4Ghz 200 x 20.

I got 200 x 20 stable with 1.31V (BIOS), I then went for 200 x 21 (4.2Ghz) and needed 1.381V...

Moving onto 4.4Ghz, I tried at first with 1.45V and a QPI/VTT of 1.335V, this posted but crashed at the windows loading screen, I then tried 1.46V and 1.335V, this got me alittle further but not quite into windows, I got a BSOD saying 0x000000124, using the below for reference I tried increasing both Vcore and QPI to 1.475V and 1.415V respectively, this got me into windows and I could start Prime but it BSOD on me within about a minute.

Seems to me like it needs more Vcore, maybe 1.54V? Not worth it for 200Mhz over 4.2Ghz...oh well.

BSOD codes for overclocking

0x101 = increase vcore

0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is

0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore

0x1E = increase vcore

0x3B = increase vcore

0x3D = increase vcore

0xD1 = QPI/VTT, increase/decrease as necessary

0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances

0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x

0x109 = Not enough or too Much memory voltage

0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)

No more volts,or you will crash the cpu.

Up qpi/vtt to 1.48-1.54v

No more than 1.43v vcore anything past this could damage cpu.

cpu-pll 1.86-1.90v.

Ram 1.64-1.66v

Temps max 70c.

I think 4.2ghz is good for i7-960 on an older x58 mobo

 

[tinytomlogan]

1.52vcore is too much. Get what you can on 1.45 and thats as far as your chip can go..... and even then thats still ALOT of volts for water 24/7 use

set the cpu to 200 mhz the ram to 1600 mhz and leave the qpi @ 1.3

you only need higher qpi if you run 2000mhz ram. Its much more important the get the cpu stable first.

TURN YOUR CPU VOLTS DOWN YOU ARE KILLED THAT CHIP RUNNING IT 24/7 THAT HIGH WITH JUST WATER

 

[iNoXiouZ]

Yeah I'm sticking with 4.2Ghz 200 x 21, 1600Mhz RAM 8-8-8-24 1T ..1.315V QPI, 1.381Vcore Max temp of 65C under prime.

Shame I couldn't get 4.4Ghz

Wish I had a good chip.

Thanks for your help guys.

P.S Love the vids Tom, I'm one of your many subs.
