Which boards have you seen or think can reach a 5 GHz OC on an i7?

I've only been able to find two EVGA X58 Classified and one DFI Lanparty DK X58-T3eH6, although the DFI reached it with liquid nitrogen.

I doubt anyone could sustain a 5 GHz OC for 24/7 use and I know that the actual processor plays a large role as well.
I'm just interested in knowing which boards have that capability based on quality, R&D and/or anything else they've done to achieve that high of an OC.

Im gonna go out on a limb here and say i think any x58 board aside from maybe the smackover (and with a custom bios, that prolly can too) can reach 5ghz all day anyday.

....Wait, here is intels shitty smackover @ 5ghz
http://www.xtremesystems.org/f...81&highlight=smackover

dozens upon dozens of low-end Asus/ASRock/DFI/EVGA/Foxconn/MSI/Biostar/Intel boards are reaching 5ghz on XS. 5ghz isnt extreme overclocking anymore.

*edit*

...That smackover is doing 5.7ghz actually, on a c0, on a cascade

Need anymore proof that any x58 can do 5ghz?

4GHz is a great OC and for that, youll need high end air cooling. None do 5GHz without -40c cooling.

you don't read the posts before replying do you?

Ben90 just provided a link showing 5GHz on air cooling. Granted, its certainly not going to be safe and probably not stable, but they did it.

That being said, 5GHz definitely won't be practical. Even if we could get one stable for 24/7 use it would probably require a great water setup to keep it stable and probably wouldn't be too safe anyways. Right now I think 4.5GHz is about the max one could expect from current i7s for a 24/7 overclock, with 4-4.2GHz being the more practical max.

But yeah, now that the memory controller is integrated, the motherboard and chipset is going to become less of a factor in the limits of the overclock. We're going to have to wait until 32nm and perhaps smaller before we think about 5GHz as something we could see 24/7.

If no one is BSing stuff on XS, im fairly confident 5ghz will be the new "standard" for high end water cooling systems and lucky air-coolers will get around 4.7ghz.

Obviously these are just my speculations, with no concrete facts to back it up aside from the few people who may or may not have an i9 chip in their hands under l2n.

alot of the XS pics are suicide runs.. ask for a 24/7 pic and see how fast the user/member will produce one.... one guy i asked still hasn't produced a full Prime95 run or any long-test stability run on a board I was asking about.... i think he showed a 47min run :thumbsup: :roll: plus the forum style totally sucks

ummmm...

no..... I dont call TRUE's and Megahalems on push/pull with 400cfm combined deltas typical AIR.
I mean if it sounds louder then a Boeing 747, it should be called a JET Propeller. Not a Fan. :p

u need massive voltages even on an i9... and thats 32nm.

OP that madshrimps link you linked...

i know about 5 people on that list personally..

Not one of them is considered "typical".

Infact they would make me look like a noob overclocker... which will probably make u look like an infant.

Dont take those links too seriously... these guys are showing u the upper apex of what the chip can do.

You can run at 5GHz 24/7 as long you as hire someone to continously pour liquid nitrogen or helium and don't mind a maximum lifespan of probably a few months, to a year at best.

+1, unless you really want to run that jet engine for 24/7 you need to have probably like a ventilator to you processor running at 5ghz

My apologies for not making myself more clear, I was in a hurry when I made this post.
I had actually finished a multiquote reply for everyone but accidentally hit cancel so I decided to post the next day but then the forums died; Speaking of which there's some things I like about the new forums and some things I don't like, one thing I'll miss for sure is the portraits from the old forums but anyways I'll continue with replies for now.

Im gonna go out on a limb here and say i think any x58 board aside from maybe the smackover (and with a custom bios, that prolly can too) can reach 5ghz all day anyday.

He did manage to OC to 5 GHz, the topic derailed alot because the poster was sworn to secrecy under NDA or something.
Apparently the processor was not only ridiculously cherry picked but it was mentioned that it had been modified to ignore temperature sensors, there was also mention that it wasn't a retail chip at all.

Either way that could or could not have lead to those clocks under a smackover, I'm not so sure most x58 boards can reach 5 GHz clocks and pass a few stress tests.

4GHz is a great OC and for that, youll need high end air cooling. None do 5GHz without -40c cooling.

I think you're trying to say you won't be able to do 5 GHz 24/7 unless you have -40c, if so then I'd have to partially agree, I don't think it would be wise to run 5 GHz on air or water 24/7.
If anyone was truly attempting to OC to 5 GHz or higher for 24/7 use I'd hope they would at least have a phase change to cool it.

5GHz definitely won't be practical. Even if we could get one stable for 24/7 use it would probably require a great water setup to keep it stable and probably wouldn't be too safe anyways. Right now I think 4.5GHz is about the max one could expect from current i7s for a 24/7 overclock, with 4-4.2GHz being the more practical max.

I agree, although there's other variables I'm considering such as the 300% higher gold content in the CPU socket.
This could be why I've seen more MBs with that feature reaching higher clocks on average.

If no one is BSing stuff on XS, im fairly confident 5ghz will be the new "standard" for high end water cooling systems and lucky air-coolers will get around 4.7ghz.

Obviously these are just my speculations, with no concrete facts to back it up aside from the few people who may or may not have an i9 chip in their hands under l2n.

I don't think so, but I'm fairly confident that MB quality may, should, does, contribute in some portion to higher more stable clocks than a lower quality MB.

alot of the XS pics are suicide runs.. ask for a 24/7 pic and see how fast the user/member will produce one.... one guy i asked still hasn't produced a full Prime95 run or any long-test stability run on a board I was asking about.... i think he showed a 47min run :thumbsup: :roll: plus the forum style totally sucks

Yeah, reaching stupidly high clocks is one thing, but proving you can run them stable is a different story.
The forum style is rather bland.

Mhmm, I've still got plenty of questions on queue that I'm going to barrage you with regarding WC.

You can run at 5GHz 24/7 as long you as hire someone to continously pour liquid nitrogen or helium and don't mind a maximum lifespan of probably a few months, to a year at best.

Yeah, my intentions aren't to actually reach 5 GHz but more or less base my MB selection based on highest clocks reached at stable levels.


:(

exactly what I was thinking. 5gig would kill your chip fast.


And what do you want to do with it once you have a 5gig pc?

Ah, the possibilities.

+1, unless you really want to run that jet engine for 24/7 you need to have probably like a ventilator to you processor running at 5ghz

Or just dump everything into non-conductive fluid combined with watercooling the parts and then a seperate rad to watercool the actual nonconductive fluid, then again that's alot more expensive than phase change and more or less you run a higher risk with your parts degrading over time depending on the type of fluid you use.

Note A0 stepping. Also when i said "standard" i meant target.. Much like how 4ghz is the target (standard to shoot for) for q9550's. A lot make it, and a lot don't. But im not very articulate i guess, and im too lazy to edit :(

Maybe once Aigo gets his B0, it wouldn't be breaking any NDAs if he gave us a % on how much overclocking headroom increased (if at all) since we don't have concrete numbers from him to begin with... But i have no idea how NDA's work lol, so just hoping

no..... I dont call TRUE's and Megahalems on push/pull with 400cfm combined deltas typical AIR.
I mean if it sounds louder then a Boeing 747, it should be called a JET Propeller. Not a Fan. :p

I had someone do some tests for me just to see where the Megahalems tops out at. Just over 175CFM is IT. After that increasing airflow yields no increase in performance. (but makes a whole lot of noise!) Airflow was measured with an Alnor Balometer and was actual airflow through the heatsink itself so to get TRUE 175CFM would take an interesting combination of hardware. They used a 20hp vane-axial fan with ducting system and actually were able to force over 2000CFM through the heatsink at full power!

FWIW I have several 1366 systems with 3520's that were cherry picked for me. The slowest one is at 4.01GHz (1.15V) and the fastest one is 4.4GHz (1.3V) all cooled with Megahalems shadows coolers. The warmest will hit low 80's on Linpack after an hour. My ambient is in the mid to upper 60's (F), however.

I cannot complain. I'm not allowed to use water cooling and honestly don't need it. The fastest CPU they had did manage 4.8GHz at 1.45V with chilled water cooling running about 55C under full load. Pathetic I guess since it was less than 5GHz. (although one 3540 was doing 5.2GHz with cascade refrigeration (-88C load!)). I wanted that chip but the POS DFI board they were using blew its MOSFETS and (supposedly) the CPU died too. (I would not be surprised if it's in a cave keeping someone warm humming along at nearly 5GHz though!) I've killed boards and the CPU always lives. Even had a board torn nearly in three pieces and under water for five days and the cpu survived! LGAs are tough puppies!

4.6 Ghz @ 1.344 volts sounds very impressive to me. I think they hit the wall after this though (I have seen other published results showing 4.7+ Ghz requiring a lot more voltage).

If I run a better cooler could I lower the voltages needed for my overclocks? Or does cooling have nothing to do with this?

You don't seek better cooling to get higher MHz. Rather you use more powerful cooling to maintain reasonable temperatures for 24/7 loads.

Most chips have a hockey stick curve on VCORE required to maintain stability. You want to stay just on the left of that curve. Once you start getting above 1.3-1.4v on Nehalem your temps will skyrocket UNLESS you have cooling that's besting the best air coolers. There are no shortcuts or ways around this. (short of putting your PC outside on a snowy night!)
