is 5 ghz the new 4ghz? -Sandy Bridge

post #1 of 75
Thread Starter 
Or are the reviewers running them at ridiculous voltages for the sake of testing?

ridiculous voltages - OC3D needed almost 1.56v for 5 ghz(4989mhz) on the 2600k.

What would be a more realistic 24/7 OC just wanna hear some opinions =)

Are the 32nm chips able to handle more voltage? OC3D showed load temps @ 1.56v were 74c (on a D-14 air cooler with 3 fans mounted). Impressive considering the massive voltage.

That is my first concern when I saw 5.2ghz on air.
But I also read that the sandy bridge chips overclock very well on air, but don't gain much when put under extreme cooling.

I think in the next few years chips are going to start having 4ghz as a normal clock speed.

Honestly, I think it will depend on the person. If you're willing to put that much voltage to your chip (regardless of temp), I say go for it. What I want to know is the actual lifespan of a chip with 1.56 voltage put through it. I mean, I know that the SB architecture is supposed to be better and all but even with all the older Intel chips, wasn't 1.4 the maximum?

If I'm understanding this correctly, there's a maximum that all the current SB chips will able to achieve in terms of clock speed regardless of cooling.

We'll have to wait to see what Intel has on the specs.

1.56 seems steep, but at the same time it's only 1.56 volts.

Probably wrong on this - but thats how much voltage a AAA battery puts out.

More heat = more voltage - at least in previous generations of chips. AMD chips for instance like less voltage, but colder temps. People can run benchmarks under LN2 at much higher clocks and with the same amount of voltage that people on water suicide with.

Only a limited number of chips will hit 5mhz, if I remember right less then 10%. Less then 30% will hit 4.5mhz. 50% will be less then 4.4mhz.

Sorry I was wrong

Really??? Where did you hear that? I was under the impression that the majority (a good 90%) could hit the 5Ghz+.

He has a 980x, his numbers come from the same place his pain is coming from.

Wait so youre saying that those SB that got 5.1GHz were cherry picked?

LMAO.

But seriously, he was quoting an asus rep. I read the post somewhere on this forum a day ago. Where? I can't remember.

Ability, yes but it all depends on people preference on how far they are going to OC on them. Some like having headroom, some like to have bragging rights.

I like to say 4.5GHz would be the average frequency that people will OC on them since it looks like a stable OC for SBs.
