TPU's Core i7 Overclocking and Feedback

[Jakethesnake011]

I think the TRUE and 2 ultra kaze 3000rpm fans, are a good choice. I also lapped the heatsink and it helped lowering temps and I also pressure modded the True, that has helped stabilize the temps of each core, they are only about 4 to 5 degrees off from each other, before the pressure mod I was about 7-9 degrees off from each core.

 

[Jakethesnake011]

Fit,
I am wondering if you can give me some insight on how you were able to get past a base clock of 200 and be stable with the UD5, I have been unlucky in finding a sable clock over 200, I got to 205 and it lasted 6 minutes in a LinX run, and then 210 BSOD's in the 2nd 3dmark vantage CPU run. How stable is your 4.4ghz? I have been giving the cpu plenty of voltage and that does ot do anything for the BSOD's. My PCI-e frequency is at 101, I have turbo on.

 

[Fitseries3]

pcie freq needs to be on auto. GB auto tunes pcie for best stability/performance.

i'll need to know your settings in the bios to know what else to tell you.

vcore
vtt
IOH
and
Vdram are most important.

try keeping your mem running around 1200mhz instead of 1600 or 2000.

 

[Jakethesnake011]

Alright I will keep the PCI-e auto, and I will lower my memory multiplier from x4 to x3, might be able to tighten timings from 7-7-7-21 to 6-6-6-18/15.
205
Vcore: BIOS: 1.43750V CPU-z: 1.408V
Vtt: 1.435V
IOH: 1.140V
Vdram: 1.680V, 1.664V real

210
Vcore: BIOS: 1.45625V CPU-z: 1.424V
Vtt: 1.475V
IOH; 1.16V
DRAM: 1.70V 1.696V real
Also changed RAM timings to 8-8-8-24 and have Uncore at x18 for both settings.

I also tried bringing the Vcore and Vtt higher and it did not give me much stability, maybe another 30-45 seconds in Linx.

I also have the other voltages on auto I only end up changing those 4 in the BIOS and the CPU PLL to 1.880V.

 

[Fitseries3]

vcore is pretty high for a D0.

vtt is real high.

try 1.37v vcore
1.26vtt
ioh 1.28
vdram 1.71

leave dram timings alone for now. you dont need to mess with them until you get cpu stable.

 

[Jakethesnake011]

So leave them at the 7-7-7-21 or the stock 9-9-9-24? The ram is rated for 9-9-9-24 at 1866 speeds. I will drop the memory ratio to x3 though.

 

[Fitseries3]

use all auto. it will auto set them at whatever the SPD timings say. thats why i say to raise vdram to 1.71. it will force the bios to use SPD to tighten the timings for you.

you need to leave timings alone until you get a good stable cpu oc first.

 

[Jakethesnake011]

Alright I will fool with this now. I just rebooted and I am missing 2 sticks of Ram, I will let you knwo how it works out when I get the other 2 dimms recognized my the OS.

 

[Fitseries3]

switch them around.

or did someone steal them?

 

[Jakethesnake011]

Even with moving the Sticks around, when I bump my memory ratio down to x3, so they would run at 1200 to 1260 Mhz I lose 2 sticks. I am wondering why such happens, even with bringing Uncore down to x12 it does not matter. So I am gonna probably leave them at x4 unless I can find a way for them to work at x3.

RAM on auto is running at 10-9-9-22 1T, at 840Mhz which will leave me much headroom for rasing the base clock or whatnot I will tighten later. I am gonna stress the CPU now with BCLK of 210x21 4.4 ghz.

 

[Thrackan]

Jake, I've had severe problems getting x12 Uncore to boot at all. x13 was fine, but x12 gave me problems every single time.

As for the air coolers question, I use a CM V10 for a 24/7 4.2ghz oc, ~1.35v on the CPU, temps are completely in line, 35-42 idle across the cores, and maximum load for my use (games/browsers/movie or episode) is about 48-52 degrees. Stress testing will make the CPU considerably hotter, naturally, but I have not met a real world scenario that has consistently made it work harder than 50%. This is truly a chip from the heavens, they were as gods the fortunate who own and tweak them.

uhhh, back to the coolers, the V10 seems to do quite well for itself, but really its way overpriced for what it is, I feel I could have achieved 90% of the results I show now with a Noctua NH-C12P, which would be my recommendation for a great i7 air cooler.

I agree. I've never seen 100% utilisation for anything apart from stress testing. It does give the most extreme circumstances and the highest temps, but it isn't realistic at all. I know we do it as a failsafe.. if it can pass stress testing, it will be fine for day to day which is less stressful. But in reality, if my O/C fails after even 1hr of Prime95, I probably wouldn't mind that much since NOTHING - no game, video convert, photoshop etc is EVER going to use 100% on all CPU for 1hr constant without a single break for it to cool down.

 

[Thrackan]

Everyone has their own definition of stability, that's OK. I like to have every possible scenario covered, including non-real-world ones, but the next person might be just fine with gaming.

I agree on all points.

stress testing is indeed valuable and I do it frequently, but I tend to agree with Davidelmo, when the PC is stable under every scenario you could possibly put it through during regular use, the stress test failing means less to me.

it varies CPU to CPU but during genuine stress testing I will let the i7 heat up to about 65 degrees, from there on in if it can last more than 10 minutes i'm fairly satisfied, and may move on to different clocks.

having settled at 4.2ghz @ 1.35v I am disappointed and ecstatic at the same time, as this is my first oc over 4ghz, and by far the best speed to vcore ratio, but most ppl with D0's are able to get 4.2 with under 1.3v..

time for more testing

Jakethesnake011 i have to agree with FIT as far as
'to much volts on vcore for a D0'.

I would recommend to use ALL auto to start with
while you start to LOWER your vcore at STOCK
speed '2.66Ghz'. Once you have got your vcore
as low as stabley possible then start your OC
in small increments with EVERYTHING ELSE on
Auto 'including mem timings'. Once you got your
CPU OC speed where you want it and stable then
work on tuning your mem. Trying to do both or
too many things at the same time only leads
to problems or setbacks.

On the topic of 100% cpu utilization in real world
situations. Guys i do updates everyday on my Linux
setup and see 100% utilization a LOT. Almost all my
apps or processes are multi-threaded and because i
always command it to do 8 JOBS at a time when compiling
updates, the apps that are not are still being compiled
along side 7 other JOBS. I can tell you guys I fully use
the abilites of this chip in linux where i have much more
control of the command structure and execution there of.

For those of you not familiar with compiling in linux. I can
control how many cores are used AND how many threads.
And believe me i push it to the max. My latest trick is
creating a swap file of 2Gb in my ram when i do my updates
so that i do not get slowed down by my hard drive. It used
to take almost 2 hours to compile GLIBC with my dual core Athlon.
I can do it in less then TEN MINUTES now. Installing the OS 'compiling'
used to take 8 hours, i do it in a little over an hour now.

Ah, a C programmer?

 

[Jupiter]

Ah, a C programmer?

Nah am not a code monkey. I support Compiz code monkeys
and our users. But i use Gentoo which is a DIY linux distro
and we compile EVERYTHING from source code. This allows
me to strip/exclude anything in the code i do NOT need.
LOL, like Microsoft, i am a control freak...

P.S. I am a MS admin at work. Linux is a hobby.

 

[Thrackan]

Gentoo, I got to get me started on a nice dual-boot setup sometime.
Ubuntu was fun, but I want more control.

Anyway, that's enough offtopic from me

I'm bored

 

[Wetbehindtheears]

Why?

 

[Binge]

I'm bored

When I'm bored I post in General Nonsense So my i7 is running like a dream. I've been playing SF4 all the time so there's not too much overclocking, but like I said it's running really well. That's my feedback...

 

[Wetbehindtheears]

I tend to drink too much when I'm bored.....

Agree Binge... gotta a nice oc so until I go water there's little to tweak...

Got home so I'll try and post some settings this wekend....

I got a little present yesterday. Anyone know what it is?
