So close yet so far away! How fast can Win7 x64 go?

[Kenmitch]

Well it's tweaker day for me today

Just trying to see how high my i5-750 will boot into Win7 x64 without exteme voltages and get me a screenshot. I'm not looking for 100% stability just a screenshot or two.

I can post at 4.62ghz and get into safe mode....But windows seems to have issues loading drivers at this speed. I got tired of playing around with settings as I got other things to do today

What's the fastest speed you have loaded Win7 x64 at? Maybe my chip is a dud

Here is the best I can get which I guess it's OK after all.

Intels stated max spec for vcore is 1.55v so it's not outa spec. On the high side but within spec....Guess I shoulda just greyed out the vcore as it's kinda twisting some peoples nipples But I choose not to hide behind the web

Intel data sheet with voltage specs can be found here http://download.intel.com/design/processor/datashts/322164.pdf Table 7.4 to be exact. Yes trying to run at this 24/7 would be a suicide mission most likely.

Thanks,
Ken

It's more than likely your mobo holding you back.

Most of them get to about 212 and then crap the bed for stability.

Damn....Well if I new I was gonna get lucky again with a good chip I might have spent more money on a MB.

Hmm....I guess I could test this theory out today as I planned on envoking the 24x multiplier today anyways. I wanna see what the best my chip will do taking advantage of the 24x 2 core load multipier. I figure the BCLK will only be in the 180's.

Thanks

1.505vcore on a LGA1156 socket?

Are you Mad?

At least check to see if its a lote socket vs a foxconn "Accident waiting to happen from overvolt" socket.

It's a LOTES socket....And yes I'm mad :biggrin:

Although I'm a responsible overclocker....If there is such a thing

The chip is under water and was idling around 42*C only in there long enough for the shot

 

[Absolution75]

voltage kills chips faster than heat

you're still in danger of damaging your chip

oh ..

then i take back my statement..

and change it to GO GO GO!!!

Have you tried booting 64bit Linux and running a complete kernel compile test through the phoronix test suite at those clocks?, try Ubuntu 9.10 64bit, its a screamer. When was it that Linux booted at 64bit?, some years before Microsoft, cant remember.

Yep, back in 2.4...

Linux was the first operating system kernel to run the x86-64 architecture in long mode, starting with the 2.4 version (prior to the physical hardware's availability).

Hmm....Not sure if this is sarcasm or what ???

I thought the official max spec from intel on vcore was 1.55v

Too much work for just a screenshot of a higher overclock. I've played with Linux before but in the end I wanted it to look just like windows

Give it a go at Ubuntu 10.4. Kernel 2.6.32 has full CPU support for Nehalem/Westmere (HT/Turbo). Download ISO, burn to CD, boot and play, its a live system. No harm done to see different OS/Kernels stabilities at high overclocks/64bit. Linux matters.

I could find a link for this at ???

Its an alpha, so it may bite. Eitherwise grab a 9.10 ISO.

Have fun.

Now adays technology is not sheer Mhz but technologies that make a chip run faster.

For example. A Pentium D 3Ghz dual core Then the Core 2 Duo 2.4Ghz is like much 100 percent faster .... Soo a i7 or gulftown can be @ 3.5Ghz and beat out a i5 @ 4.6mhz. Also what are your load temps, idle is not important. As long as your temps dont go to 70's c I would say your safe. Try to make it stable I guess. But your in dangerous voltage area there. let us know, gl,

Kinda lost me in your examples....More so on the i7 vs i5 analogy as they seem to share the same arcitecture

Anyways I have no intention of trying to stabalize at this speed I just wanted a screenshot or 2 for the hell of it....Or maybe bragging rights is more like it

Is that a suicide run? you probably shaved 1 year or 2 off that chip by going that high even for a few minutes.

Huh....Max vcore per intel is 1.55v max so I guess it would be non suicidal to say.

I guess if one wanted to try to stabalize it for 24/7 at these speeds it would most likely be a suicide run.

Guess I should have just greyed out the vcore as it's too much for some folks

Crank it up!

A fresh alkaline AA cell has a higher terminal voltage than your CPU right now!

Put your ear up to your heat sink. If you don't hear the bubbling sound of electromigration you can ratchet up the vcore to the sky. If the motherboard does not allow higher get out the soldering iron to remove the limitation!

Who needs fireworks when you can blast off on your desk?

How hot does it get under load? You are close to actively damaging your chip while you run it depending on how hot it gets (60C?). For just goofing around at 43C you'll be fine but if you ever actually load it and get up there....in other words don't make this your permanent overclock.

All I can hear is the sound of water going thru the water block

You should never suggest someone putting an ear up to a heatsink. The internet is full of idiots that would most likely try it. Just image the blister or the missing parts of the ear that your suggestion could cause

Not to mention how would one safely clean the blood out of the system?

I guess if the caps started popping it may look like fireworks!

All joking aside I don't have the intention of pumping the juice any higher nor do I plan on trying to get it stable. It was a boot into windows and take a shot thing only. No testing no load

I would much rather of heard something like the highest speed I've loaded windows was ?.??ghz

I'm sure you know that you can't force a chip to boot with voltages. It'll either do it or it won't no matter how much juice you push into it. Voltages(within reason) are more for stabalizing the chip not forcing it to run at a speed it won't run at

Hmmm perhaps the overvolting has burned out the coil in your d'Arsonval movement sarchasm meter over there. That sound wasn't electromigration after all - it was the needle bouncing off the right peg with ten times the ferocity of the windscreen wipers on a Boeing 747 running at 11 while landing in a typhoon.

People put their ears to train tracks to hear the approach of an oncoming train. I'm sure that is pretty safe too, no? (just be careful if it's cold and grizzly bears licked the rail - you don't want to be in a sticky situation!)

I'm trying to figure out why people think I'm trying to get this to be 24/7 stable. This would not be possible I'd think.

The chip was booted into windows and a screenshot was taken....The chip was under water and was @43*C on the hottest core. I did not do any stress testing on the chip nor did I start pumping the juice to try making it stable....But I would think the temps would have been about the same as if someone used the stock cooler and did a modest overclock and then ran something like Intel Burn Test most likely

All I wanted was a screen shot or 2 not a exteme overclocked i5-750.

Now that you put it in plain english it's a little easier to comprehend

No harm no foul....Thanks for clearing that up for me

oh ok my bad

 

[spinejam]

1.505 vcore! well, that's pretty high -- balls to the walls high -- sizzle me schnizzles high!

 

[aigomorla]

Hmm....Not sure if this is sarcasm or what ???

No i was pointing at this...

Crank it up!

but not to her voltages.

If you play with Vtt a bit more i think you can probably squeeze a bit more out of the cpu.
