Core i7/X58 Overclocking Thread

[rge]

If you pace yourself just right, we will still be here after killing our gulftowns with too much voltage .

[momoto]

Cooling was changed from MUGEN∞2(SCMG-2000) to Megahalems. 　It and grease changed from AS-05 to Thermal Elixer.

206×21＝4322MHz Vcore 1.2250V(BIOS)

4.92 spi 32m with open window ambients. Need ram capable of 2140 would get better time...my 1600 rated maxes ~2000 with cas 9.

^^^^ very good job. Amazing CPU. How much better are your temps now?

[emertX]

emertX,thats incredible,but with a chip like this
you really should consider moving somewhere
like iceland or alaska so you can keep that OC
24/7.it not fair to the chipJust kidding
but seriously thats a great OC,good job

Yeah, I'd like to have these temps 24/7, but just 4,2GHz are that hot at load with 23°C ambient in my living room.

Haha, agreed.
Really god job there!

Thanks bro.

@4.2GHZ is a great 24/7 OC, but Your max core-temp for @4.62GHZ is 67'C under Prime-load.
This is not too hot, but also is great for 24/7 use, unless you are using some kind of "exotic"-cooling on this run. What kind of cooling are you using?

My kind of exotic cooling (Not mine, just picked up at google!!!):
Wintergarten Haus1.jpg

Putting the pc in there, open all windows and doors, hope for good temps outside - it had 11°C then - and let the machine run!

I have a good friend from america who didn't know my radiator, maybe you also don't know - so here it is:

I have 9 x 120's on it!

Yep, 4.6x is max I have seen prime or linx for any length of time. And most use abnormally low ambients to get 4.6, including myself.

At 4.4ghz, my i950 is very stable whether 72 load or 90C load (turned fans off on rad to get 90s).

At 4.5, got 11+ hrs prime and linx max mem, but with indigo tim and 23C ambients and 2rads to keep load temps in mid 70's. If load gets in high 80s = bsod.

At 4.6, I can get prime only few hours, and linx 20 run max mem, but with 15C ambients (outside temps). Inside temps = bsod.

My aim was to run the computer as fast as it can do...due to the fact, that the pcie-clock is limited by Gigabyte at 103.5 MHz I can't go further. There's a Solder mod, but I don't have the heart to do that. Except this fact, the board is impressive and easy to handle to! I now know, that it is possible to run 4,6 GHz, but I don't need it!

@ emertX

very good job bro, that is a might fine CPU you got there my friend

Thanks a lot bro.....

Yeah, specially with 920 or w3520, a couple of BCLK up, and many motherboards won't even boot at 222+ with x21 multi.
It takes a really good CPU-batch (+ good MB, RAM and cooling too) to get it Prime-stable at @4.6GHZ+.
It is the ultimate 24/7 OC on the current platform, I guess.

I know people running 4,8 on Chiller and one who ran 5GHz primestable with LN2!!!

[Sniper]

@emertX: You got a really nice cpu there, low voltage but also quite hot. If you you do the PCIe mod on your GB, I think you'll find that its easier to get 4.6+ stable with slightly less vcore at 104+ on the pci. Thats my experience atleast.

[emertX]

Yeah I'd like to do that, but I don't want to break my mobo...did you do the mod?

[Sniper]

Yes, max bootable/stable bclk now is 232 (228 before mod). Think i need cold to get further.

[emertX]

How did you do that? Was it easy?

[emertX]

Could you explain and tell with which voltages you got 4,7GHz primestable? Edit:
Just saw, you just took 4 Threads...Mine is with 8 Threads.

[Sam_oslo]

I have 9 x 120's on it!

@5GHZ Primestable is great, but LN2 won't work for 24/7 you know.

That 9x120 looks good. Sniper got the same batch# as you, and I remember he was talking about low-voltages but extra heat on this batch#.
I see 9x120 got the heat under control on that hot CPU, good job . With this kind of "exotic"-cooling, you should go for @4.7GHZ now, ... go go ..

[Sniper]

The mod is probably easy if your good at soldering, think hicoockie said he used 1 min to do it. For me it was not that easy, but got it in the end.

In normal room temp (22-24 degrees) with 2 360 rads with 1200/1400 rpm fans my W3520 can do ~3640 HT on and ~3750 without HT and still be under 80 degrees in RealTemp for Linx/Prime.

24/7 I'm running at 4515 1.328vcore 1.3vtt and fans turned down to ~700 rpm.

[emertX]

Seems to be the same as mine, but I'm using 1,34Vtt and 1,29V Vcore @ 4,5

Do you still have the board?
Could you take a photo from the solder?

[vaio]

Do you Giga owners find your board undervolts much?
1.2 in bios gives me 1.152 in CPU-Z.

[Sniper]

@emertX: The picture in the mod thread is better than what I can take.

@vaio: Yes, that is typicall for GB.

[vaio]

Thanks Sniper.

Yes, JC has advised me to lock down LLC.....will see if that settles her down.

[emertX]

Oh man...if I will gain that much with the mod??? My board is primestable @ 19x226 with 8 threads, so it is very good, and I do not want to damage it due to some points in 3dmark...

[vaio]

Up to page 66 of this epic novel

Seemingly solid at.

200 x 19 HT on.....1.212v in bios (1.168 in Windows).
Makes for a decent lil cruncher.

[Chicken Patty]

pup, you got an i7? Where as I?

[vaio]

Needed a new workhorse to help me back into the top 40 at Poem
Currently alternating between Poem and WCG trek.

[Chicken Patty]

cool, what are the specs on that rig dude?

[vaio]

In sig

Running nice and conservative 3.8 at the moment.

200 x 19 HT on/Turbo off.
1.212v bios.....1.168 in Windows......temp max 70c under crunchy load-in a closed room with no window.



Acts up at anything over 3.8 so leaving her be for now.
Voltages need tweaking a little to go higher (if she can) but right now she seems rock solid so leaving her be.

My lean mean Poem machine

[Chicken Patty]

very nice pup, I didn't notice the specs were in the sig dude. Gotta love i7's for crunching bro, they are amazing.
