The i7 Overclocking Study Thread... post your OC settings.

Hello everybody. As some of you may know from my postings in the general i7 overclocking thread, I am attempting to collect data on people's i7 overclocks in order to figure out what allows some users to get relatively high OC's on such low voltages.

My hypothesis is that the secrete is in how all the various settings and voltages relate to each other... in a sort of harmony. Thus many of us who seem stuck at high voltage overclocks may be in that situation more as a result of an unbalance in settings/voltages than in your "unlucky" batch number.

So... here is what I need in order to complete this study: Will those of you who have relatively low voltage 3.8ghz i7 overclocks and higher please post in your complete settings and voltages, as well as basic system info such as your CPU, batch number (if you know it), motherboard, and CPU cooler. Leave nothing out please. It is very important that I have equivalent data from each of you in order to compare them precisely. Also, will you please try to post the data in a roughly similar fashion that I give below in the example.

Heres an example of how I'd like the data to be posted. But if you have more settings or voltages please include them, as this is only a basic example.

================================================== ==================================

Thats it, I just need the data. If you want to include other info or notes as well that would be fine. Hopefully all this will help us unlock the mysteries of the i7. Once I have a good amount of data collected I will compile it, test, and of course share all the results. And if any other members would like to take the data and run tests of their own that would be great as well. Thanks to everybody in advance for donating your info ;)

here are mine

But not Prime blend? I have to raise my voltage up a bit for that (usually QPI voltage also) vs LinX testing. I bet the system would be stable 99% of the time if you are LinX stable though.

Edit: I found out I was using just too little memory with LinX to test properly. I had issues with it not loading the system fully because I was telling it to use too much memory. I just need to keep making it re-sync with what is available and use that as long as it's > 13000 problem size with my 4 gigs memory. I actually needed a single step bump for LinX stability for my current OC target because my voltage was still sagging a bit only under LinX. The single step voltage bump kept the load voltage where it was on Prime blend for 11 hours and it was then fine on LinX with the proper memory usage. I will post settings.

A W E S O M E work there! Many thanks.

Thanks for compiling that data Avan. Unfortunately my data for 3.8ghz is wrong as I was still working on the OC and being bad and posting early out of excitement. I needed one more bump in voltage because I was testing with LinX improperly. My problem size was too small by about 3000. Here are my complete settings:

Okay, I'll grab the info from this thread and the batch # thread and update the list tonight when I get home. I don't have the compiled list here at work or I'd do it now.

I'm still going over the info, will start testing soon. Keep the numbers coming though... more couldn't hurt.

Nice thread...Still working on mine can't wait for the 965 asus p6t owners to chime in!

I'm at 4.2 but still working on it...

I'm curious what the ambient temperature was for those readings, fan models (and rpm)/radiator(s) used, and the orientation of your EK-Supreme.

I hit 89C in an 18C ambient @ 4.2ghz on a TRUE. I'm hitting 89C in a 25C ambient @ only 3.990 ghz. I'm still planning my first WC loop.

Sorry i got the quot wrong, i was refering to you, you the one that has F6C lol :)

what do you think of ir m8?

Thanks

Wow, that core voltage is incredibly low. Seems weird that your temps ended up so high after a long stress test. Also, what are C1E and CState and how do they keep idle temps low? Are they on by default?

Looks like you were asking the other guy but my thoughts on the F5e BIOS: I like it alot as I got the temp drops from the F5 series, S3 resume works as long as I wait at least 30 sec before attempting to wake and my 4.095 with Turbo and HT is stable. FYI I tried F6a and it did not work well for me and most recently I tried F6e and my overclock would BSD very quickly with it on LinX and the killer was it will stop you from going back to older BIOS using Q-Flash, which was really annoying. I was able to get back by creating a USB Boot Disk and reflashing that way. Instructions on tweaktown by (lsdmeasap).

In looking at your settings and esp. temps I am thinking of playing with turning HT off and trying F6c. I know your block is better than mine for quad cores, and your rad is better as well but a 15 degree difference in LinX testing is huge!!

My goal is to get to 4.2 stable with HT on and temps below 85 with LinX but I have not gotten there yet.

I am going to get a new block for sure but waiting on Hondacity's review of the HK vs the K350.

2 slick post a shot of CPUz, and the memory tab also if you can please.

I returned everything to stock right now :P
it frustrated me that i cant get it stable...

How did you get 4ghz stable? What cooling you using?

heres my log over at TPU, it has updates throughout the thread, but the components remained the same as the first post.

http://forums.techpowerup.com/showthread.php?t=82607

I can do 4.3 GHz HT on, stable for about an hour and a half just for benching, I dont run the rig at that setting daily. voltage is not within safe specs. Only do it for short periods of benching.

here is a shot

What do u keep ur speed at normal use?

oh liquid cooling :P maybe i go that route later but i dun even know if i can push my cpu anymore cant even get a good oc with good air cooling :(

if you drop your ram didiver to six, and leave everything else the same, is is stable?


nice S2k BTW :up:

here are my daily settings, i have crunched over 86 hours with these settings, not one BSOD or restart or hang. I game, and bench on this too!


if you notice while browsing i am also crunching in the background. Rock solid stable dude:


http://img.techpowerup.org/090321/Capture117.jpg

I have it at this setting right now

BCLK: 200
Mul: 19x
Dram: 1603 ( 8x )
UNCLK: 3206 ( 2x )
QPI LINK SPD: 7200MT/s

Vcore: 1.35v
PTT: Auto
QPI: 1.35v

which didiver?

can u show me your setting
but your doing water cooling so it shouldnt be a problem..
I'm still on air so i doubt i can get it stable with 4ghz
I'll be happy to get it stable at 3.8ghz with ht on :(

look before your last posts, those are my settings.


the RAM divider, drop it from 8x to 6x

should i drop the dram voltage if i drop it down to 6x?

no it wont hurt to leave it like that, maybe the ram needs some juice and thats why you are not beeing stable. Try bringing it down to 6x first. Voltage the same. See if it works. Trial and Error my friend, trial and error.

Try that and report back.

did as you say hope this work

my voltage is liek this
vcore: 1.35v
QPI: 1.35v
dram: 1.66v

should be okay>?

i have qpi link speed at 18 x?

try those settings, we'll see if it was your ram/memory controller taking a :banana::banana::banana::banana: with the RAM at that speed. IF its still not stable then its going to take tweaking something else.


QPI link speed is correct at 18x.

i try to prime it now :( hope it works...

Because it drops volts/speed. Gets the idle temps to the lower 30's.

4hrs so far temps at 86 havent got a bsod yet lol

good. Looks like it was either your ram or your memory controller having a hard time being stable at higher clocks. Keep the RAM like that and go from there. If it continues to be stable, try to lower your vcore little by little. If you can be stable at lower vcore thats good. Lower voltage, cooler temps :up:

yeah i hope it run stable right now at like this than i'll try lowering the vcore
do i have to touch the qpi/dram voltage?

you can leave that how it is.

well so far 5hrs and no bsod yet so i guess good news for now :P
How much for a basic water cooling system?

FYI I tried F6a and it did not work well for me and most recently I tried F6e and my overclock would BSD very quickly with it on LinX and the killer was it will stop you from going back to older BIOS using Q-Flash, which was really annoying. I was able to get back by creating a USB Boot Disk and reflashing that way. Instructions on tweaktown by (lsdmeasap).

#1 - Where do you get F5E? Is it an official BIOS or beta?

#2 - I received my UD5 with F4 and flashed it to F5. Overclocked to 4.0GHz but now I can't get it to wake up from sleep (S3 suspend). I thought the issue was fixed with the F5 bios...

Computer powers on fine but the screen is black. I have to do a hard reset in order to get back into Windows. Any ideas?

what do you think of ir m8?

Thanks

---

Yeah :) just messing.

Well the Bios is all ok, Was working with the same settings as earlier F5 bios settings, no change in Voltages, atleast for me, and ET6 is working also.

Thought it was a good one, but then, it started, now and then when i were rebooting, it got to a blank screen and i had to reset and it got to OC failure screen. very annoying, So now i have switched to the great F5G that is working flawlessly so far as before, no bad reboots etc. only thing, S3 and ET6 wont work with this, but i never use Sleep so why bother, ET6 is not a must either, so im sticking with F5G so far.

Yeah, F5E is a beta bios, all bios'es with letters are BETA.. those without are the Final one, and check out Tweaktown Gigabyte forum for latest and all previous beta bios. great place actually got all progs and stuff you need :)

Well NO F5 Bios is working with S3, dunno if it's even fixed until now, many complains over it, only working i think is with F3 bios?

u can tell me what is your BIOS version? :confused:

thanks.

There's no way to tell of that screenshot im afraid?

P06

Can someone tell me how to determine my batch #?

Settings are:

BCLK 190
Multiplier 20x
CPU voltage: 1.2125
QPI/DRAM voltage: 1.2
DRAM Bus voltage: 1.6
Speedstep and turbo OFF

Running an ocz platinum 6gb 1600 set of RAM at 1520 @ 7-7-7-18 1T timings.

Passed 12 hours of prime95 blend temps capping around 78. Idles in the 38-41 range (sometimes lower). I can take a screenshot if required, although I just closed prime after leaving it on overnight.

Yeah, you have to look at the BOX the cpu came from, look at the FPO # batch. down in the left if I recall.
or you can look at the cpu itself, but seems kinda hard when its in the use :)

is running my Corsair Dominators 6gb 1600MHZ at 1203MHZ with 6-6-6-18 1T safe setting? 1.66v

your batch number is on the box
3 - Factory
8- Year (2008)
41- Week in year
A525 - Lot#

anyone have the same batch as mine?

dude did you test the other one you had at your house? Not the one we ran prime on that you were using when I was over this passing weekend.

Yes I tested it under water and it did very good but not as good as the one I'm keeping. :D

Is that yours in the pic or is it the batch like mine?

very good Mario. Your chip is very good bro. Have the temps improved on your CPU now that the thermal compound is more settled in?

CPU speed: 4.4Ghz

QPI: AUTO
HT: On
PCIE freq: 101Mhz
LLC: on
CPU differential amplitude: 900mV
CPU clock skew: normal
CPU spread spectrum: disabled
PCIE clock skew: normal
PCIE spread spectrum: disabled
Everything else: Untouched

All other voltages: Untouched

Sorry it would be really difficult to remove my cpu waterblock and clean off the paste just to see the batch number!

The cpu cooler is a heatkillerv3 lt with mx2 paste, quad thermochill pa series rad, double feser rad but i also have my 5870, and entire board watercooled aswell.

Temps dont go above 80-85c.

10 and half hours prime stable (after 10 and half hours i decided to stop prime so it hasnt blue screened on prime on those settings)

at 4.2 ghz i had only rough settings in and they seemed to work fine, 8 hours prime stable until i turned it off

CPU speed: 4.2Ghz
920D0

RAM timings: 6-7-6-18-1T


CPU Ratio: 21x
BCLK: 200
DRAM: 1600 mhz

hope this helps and is not redundant without a batch number! sorry again!!
