So, the MHz difference won't matter with memory or peripherals? The m.b. spec has<br />

<pre><code class="code-1 nolinks" id="code-20-42389864-1"><span>Supported RAM</span>
<span></span>
<span>    Bus Clock       1333 MHz, 1066 MHz</span>
<span>    Features        Dual channel memory architecture</span>
<span>    Speed           PC3-10600, PC3-8500</span>
<span>    Max Size        16 GB</span>
<span>    Technology      DDR3</span>

Thanks

<br />
It won't matter. &nbsp;1333 seems to be the memory required by the CPU but the slower type 1066 should work as well.

I don't recall a time when GHz mattered. &nbsp;Most CPUs these days bounce around the GHz. &nbsp;In the last 10 seconds, I've been as low as 1.63 and as high as 2.37 GHz on a CPU that goes up to 3.2 GHz.

&gt;&gt; &nbsp;<i>None of the links above is exactly for CM model, but for M2 model and on the second link current CPU is not listed. :)</i><br />
<br />
<b>Mistake on my part</b>. &nbsp;Yes, the links are for the M2 model. &nbsp;But the G30 and the i5-3470 are both in the second link.<br />
<br />
The G30 is Sandy Bridge and the i5-3470 is Ivy Bridge.<br />
<br />
In theory a Sandy Bridge motherboard should support Ivy Bridge but a BIOS update if it exists is recommended.
</div>


<div>
Yes, my bad, G630 is listed down I did not scroll that much. Still that is not support CPU list for CM motherboard. <br />
<br />
But, many &quot;early&quot; Sandy Bridge motherboards do not support Ivy Bridge CPUs at all, or support only some subset of Ivy Bridge CPUs.<br />
<br />
For this motherboard support is not provided by ECS. In that case BIOS upgrade and CPU support should be obtained from elsewhere, not from ECS (I guess that on PC case should be written PC manufacturer). And typically, in the case that BIOS is not supported by motherboard manufacturer, from my experience, there is no new BIOS upgrade to support next generation of CPUs for those motherboards even if CPUs can be supported by chipset.

<div>
jmarkfoley &nbsp;- may i ask why you want to upgrade the cpu ? there may be better solutions than that
</div>


<div>
Predrag: Here is the spec for the CM motherboard: <a href="http://powerspec.com/systems/system_components.phtml?component=1935&selection=B632" rel="ugc">http://powerspec.com/systems/system_components.phtml?component=1935&selection=B632</a>. It is, in fact, a Powerspec PC. It lists supporting Intel® Core™ i5-2000 series in LGA1155. Given that, are we still sure the i5-3470 will work? Apparently I can get a BIOS upgrade here: <a href="http://www.ecs.com.tw/ECSWebSite/Product/Product_DOWNLOAD.aspx?DetailID=1090&CategoryID=1&DetailName=Feature&MenuID=24&LanID=0" rel="ugc">http://www.ecs.com.tw/ECSWebSite/Product/Product_DOWNLOAD.aspx?DetailID=1090&CategoryID=1&DetailName=Feature&MenuID=24&LanID=0</a>&nbsp;(actually, probably not an upgrade. It lists version 1.0).<br />

I have two such computers and can get the i5-3470 from newegg for $170 each. Seems like a cheap upgrade ... if it will work!
</div>


<div>
Intel 3k CPUs are not listed, so there is no guarantee that it will work. I agree with Lee W. that 170$ investment is too expensive. I bought 2 months ago HP &nbsp;Elitedesk 800 G2 SFF (4GB ram/500GB HDD/i5-6500) for 260$ on eBuy. So, most likely, you can buy PC including CPU for that amount of money.<br />
&nbsp;<br />
Listed motherboard is H55H-CM (1156 chipset) not H61H2-CM, so flashing motherboard with that BIOS is not recommended.
</div>


<div>
OK, you've all convinced me. I'll not buy the older i5-3470's. Plus, there is a deal at my local Microcenter for 2 i5-7600's with 1151 socket, two for $230. I'll get a couple of new motherboards and done!
</div>


<div>
Don't forget about RAM too (DDR4) and currently RAM is pricey.<br />
:)
</div>


<div>
Yeah, forgot about that. I thought I could use the DDR3, but no!

I have a ECS H61H2-CM 1.0 mothboard with currently a Intel Pentium G630 2.7 GHz processor. The board has an LGA 1155 socket. The m.b. spec says this board will take Core i5, Core i3, Celeron ... etc. processors. I am looking to upgrade the processor to an i5-3470, but it runs at 3.2GHz whereas the current processor is 2.7 GHz. Can I do this upgrade?
