Iam aware the 3470 is not a K processor, AND, iam not really wanting to OC as I dont play games (multi-tasking music production only) - but if i ever DID want to overclock this processor, whats the cheapest chipset I can do it on? I read somewhere of someone having his up to 3.8Ghz and someone else said its limited to 3.6Ghz? - im assuming you have too change the BCLK - will this adjust memory/bus speeds too?

any advice on this would be helpfull

I was going to get H77 chipset but now thinking of H61 too save money, preferably gigabyte boards with PCI-E x1 slots for expansion such as wifi/raid


thanks
 
Might as well get a cheap Z77 board just in case you want to jump to a K chip, not sure if the H** boards will allow you to raise the turbo limits either.

As for the overclocking part, it's more of a "limited" overclock since all you're doing is raising the turbo speeds and not the stock speeds:

So it should be 400mhz higher than the current turbo speeds.
 
thanks

is this an intel thing? the chips max turbo is 3.6Ghz - so does this mean i can get the processor running at 4Ghz on one core only? (3.9 on 2 , 3.8 on 3 and 3.7 on 4)

how can I find out which boards support this?

and is Z77 the only boards you can overclock Ivy Bridge K chips with?
 
Yes you can only overclock with the multiplier on a Z77 / Z76 or P67 (dependant on BIOS revision) and you need a K chip to do so.
 
thanks Bacon - But Iam trying to find out which boards I can boost the non-k IB 3470 chip's turbo with, i aint got much cash and was gunna get H61 or possibly H77

has anyone on here overclocked the turbo to 3.8Ghz with a core-i5 3470 on a H61, H67 or H77 board?
 
Googling around the H** boards will not allow you to overclock the turbo speeds, you need a Z**/P** board. Any of those boards will allow you to do this.
 
well Iam reading its possible to get 3.8Ghz on all 4 cores without messing with bclk, one person got 4Ghz on all four cores with 105.5 bclk and 38 multi - nice to know its possible if you have the right board, now just trying to find out what board i can get that allows it within my price range (low as possible with Sata3 ports for SSD)
 
sorry - it has to be a mATX and I do prefer Gigabyte, I may consider another brand

well I have about £170 too get 8Gb (2x4) memory and motherboard and I was hoping to squeeze in a Sata3 120Gb SSD
 
Yes, but I'm just worried there may be some Z68 boards with older BIOSes that can't support Ivy Bridge yet, which would be a hassle if it was the case since you will need to buy a Sandy Bridge CPU to update it.

Not to mention it won't be native SATA 3/USB 3.0 either, which to be honest 3rd party chips are crap at doing (I disabled my USB 3.0 controller since they're so unreliable :p).
 
FWIW my Gigabyte Z77 mobos will run all four cores in a 3570 at the max single core turbo speed. So I get 3.8GHZ on all four cores. :D
So a Z77M-D3H seems to be a good mobo for you but I can't see any way of adjusting the Turbo frequency upwards.
