2500k and 3570k for quiet PC?

[grandpatzer]

I'm currently running a locked Intel i5 3.4Ghz it's using 1.05v vcore, it has a 500rpm 120mm fan and a Mugen 2 rev. B.
But I would like to have more speed, maybe 4.0 or even 4.2Ghz.

Do you guys think this is possible with unlocked CPU?

I know the 3570k is slightly better clock for clock, also it can handle more heat(?) but in return gets a bit hotter (?).

My guess is even 1.12v is propably fine, maybe I need push pull on my cooler then.

Get a 3570k and you can clock it to 4.2ghz no bother

 

[Timeless]

With a 3570K you should reach 4.0-4.2 easily without changing the vcore or cooling.
If you want to go even higher to 4.5 you just have to play around a bit with the vcore and maybe a silent fan that goes a little faster or push-pull and see what noise level and temp level is acceptable for you.

Yeh, 4.2 is very easily attainable with a 3570k

Would you guys say for my purpose the 3570k > 2500k?
How much vcore is the stock 3570k?

My current locked i5 has "big" undervolt as it's 1.05v vcore and 3.4ghz.
But you guys think that my cooling is enough for 3570k 4.0-4.2ghz?

I could add another 500rpm fan for push pull, for sandy bridge I think I'm good for vcore 1.12v, maybe even 1.2v most likely.

Edit--> a user told me the following, which suggests 2500k for me(?!)
*"Consensus is that even though Ivy is faster per clock, Sandy can typically overclock enough more to compensate for this"*

 

[seumasbeathan]

^Not true, Ivy IMO is a great clocker, Your cooling should do 4.5ghz fine on about 1.25v

 

[grandpatzer]

So the 3570k won't be too hot 4.5ghz@1.25v, obviously it's also a lottery on how good my cpu clocks.
But I'm guessing I should expect 4.3-4.6ghz@1.25v?

I think Mugen 2 rev B with push pull 500rpm 120mm 2 fans should handle SB 1.25v, I'm assuming IB is similar since it can handle more heat vs SB.

Ivy is cooler than Sandy up to around 4.5/4.6ghz.
Half of us here can get 4.5ghz at under 1.2v

I guess most IB at 4.5Ghz use alot less power aswell?

I'm mostlikely going to get a P67 motherboard which is a shame as it does not have BIOS for IB cpu's.

alot less?.. prolly less.. like 15-25 watts less.

my gigabyte P67 UD4 and 7 have ivy support.. but only the UD4 has pcie 3.0

you might re-look into the P67..

The Pure Black P67 Hydra was on good price and it has 16x/8x/8x ofcourse only PCI-E 2.0 but still should be enough for me.

It does not have BIOS for IB, so it prolly does not work with 3570k I think.

 

[airdeano]

only issue (and i could be wrong) is when using SLI, the x16 might get yanked
to x8 because of the architecture.. the gigs have had the architecture
already just not implimented till the F6 and F7 BIOS...
ESC and Sapphire mixed dual GPU im not so sure of.. it seems the first is
wired 16 but all the rest is 8 or four.

and you are correct with the BIOS.. no support. a deal on the UD4 (B3) for
cheap could get you over the hump.. ive seen them 75% off.. new old stock.

Well the motherboard I linked is only PCI-E 2.0 but it is 16x/8x/8x which is still OK imo.

But I guess you agree there is a big risk that the CPU will not be recognized in the Sapphire?

 

[airdeano]

i believe some asus, and giggies. few MSI if any from the big three.
i really cannot roll with the giggies, the overclock voltage is so much higher
than my EVGA by .03 volt on vcore. which seems to add 5°-8° on load
when above 4.5MHzand the vdroop control is whacky.. i'd look into some
z68 boards lotz are gen3 or BIOS upgradable which support ivy. MSI (G3),
UD4 and up, gen3 for asus.

Aaa nice this thread,
As i have a vs question !

Or lets say, what is the real differnce between the i5 2500K and the 3570k ?? besides one is newer

thanks in advance BTW it is F@H related.......

As far as a user is concerned they are basically the same.

Both 4 core, non hyperthreading intel chips.

Both based around a very similar "bridge" architecture. The 3570K is Ivy Bridge which is ever-so-slightly more efficient and more powerful than the 2500K which is on the Sandy Bridge architecture.

Ivy Bridge chips are also made physically smaller (although they share the same size socket). This means that Ivy Bridge chips are slightly less power demanding but equally at higher overclocks >4.5GHz the smaller size increases the local temperature on the chip.

Thank you sir !

 

[jamesriley94]

You forgot to say, the 3570k has a better integrated graphics processor, and also has a better memory controller than the Sandybridge variant.

Basically, as said - you wouldn't upgrade from a 2500K TO A 3570K - but if upgrading from an AMD Phenom for example - you'd pick Ivybridge over Sandy due to those minor improvements.

 

[grandpatzer]

Thank you sir !

Ive read a review where the 3570k got up to 10% more fps in games clock for clock.

So honestly if I was to buy a new cpu I would pay the small premium for IB over SB, also there is the PCI-E 3.0 which might not be as important...

Factor in the less powerusage aswell for IB.

 

[Master&Puppet]

Bah I don't even think about iGPUs these days

Better memory controller is a good point and I suppose native pcie 3.0 is worth a mention too.
