Lower end Ivy cpus, any good?

[pieman109]

As I was reading some reviews on the ivy cpus last night I noted they were all of the upper end procs, none of the lower end ones. The 3450 and 3550 cpus have not been reviewed by anyone as far as I could find using google. Now, I know they're not K cpus so I don't think they're multi unlocked, but I would assume they might hit 4.2, 4.5 ish when overclocked in the same way as you'd overclock an i5 750/ 760, up the fsb, drop the multi, and maybe up the v core a bit.
Now, considering the cost of these and what they "might" overclock to, they might offer an upgrade of sorts for ppl with, say, a high end Phenom II, or low end i5 750 sort of level, due to the cost, especially the 3450 at £145.
Opinions?

Hi there,

Unfortunately, with the LGA1155 CPUs you really can't change the BCLK very much - as so much is reliant on that bus. On the outside you may be able to get up to 110MHz (at the very most - most likely less), but it generally isn't recommended to push the BCLK on these CPUs.

The i5 non-K series do feature "limited" multiplier overclocking - but AFAIK it is only up to a maximum of 400MHz.

Would rather pay the extra £25 and get the 3570K TBH.

Cheers mate for the info, clarifies a lot I wasn't sure about (which is a lot ). So these ivys and sandies can't have their "fsb" increased up to 200mhz like you can on the older i5 760 'frinstance? I assume its all done on the multi?

Exactly, the BCLK (which is effectively the FSB) is very locked-down on these CPUs and you can only change them by a few % before the system becomes unstable. As you say, basically all the overclocking is done via the multiplier.

Ok mate, thats my theory out the window then

The OP should stick with what they have IMHO.

I've just started looking at these chips and the i5 3450 could be a real corker...

Not many samples on cpubenchmark

http://www.cpubenchmark.net/cpu_lookup.php?cpu=Intel+Core+i5-3450+@+3.10GHz

But I can believe it being slightly faster than an i5 2500k at stock but the // CUT HERE boosted Quick Sync will blow the 2500k away. // No HD4000

Grrrrrrrrrrrrrrrrr

Excitment dashed http://ark.intel.com/products/65511/Intel-Core-i5-3450-Processor-(6M-Cache-up-to-3_50-GHz)

HD2500 only and no VT-d - damn it

OcUK need to update the index page for IB processors ... This is clearly not a HD4000

Might go with the 3550 as my new VT-d chip and stick to video encoding on the 3770k - guess I can't have everything
