Overclocking Intel's Core 2 Duo E8400 Xeon Counterpart, the E3110
I'm sure all of our readers have seen all seen the online reviews of Intel's new Core 2 Duo E8400 and E8500 dual-core processors. They're big news. These new processors codenamed Wolfdale benefit from a die shrink from 65nm to 45nm, and improved architecture which results in better clock for clock performance compared to the Conroes. As well, L2 cache has been increased from 4MB to 6MB, and the bus speed bumped from 1066MHz to 1333MHz (quad-pumped).
Initial reports from around the web place the E8000 series Wolfdales as great overclockers. Looking at many review websites and user experiences from forums, the E8400’s and E8500’s are hitting upwards of 4GHz with air cooling without much voltage increase. Adding this performance with a retail value of around $200US, the E8400 is a great value.
The current problem with the E8000 series is availability. There aren’t many stores, if any, which have the E8400 or E8500 in stock. These processors are high in demand, and so far supply from Intel hasn’t been able to keep up.
This is where Intel’s Xeon E3110 processor comes in. On paper it has the Xeon branding, but under the hood it’s the same as the Core 2 Duo E8400. They are 45nm Socket 775 processors, and have the same 3GHz operating frequency with 1333MHz quad-pumped bus. Their architectures and instruction sets are the same as well.
As we can see, the specifications for the E8400 and E3110 are essentially the same. Getting down to it, both processors are the same. They share the same CPUID and stepping. The VID voltage range is slightly different, and this could be a result of differences in the binning specifications of the processors. It is believed that the Xeon series of CPU’s are binned processors that require less power than its standard desktop counterparts.
Availability wise in Canada, I found the Xeon E3110 to be a bit easier to find than the E8400. At the time of my order, the E3110 was in stock at a popular Canadian online retailer, but the E8400 was nowhere to be found. Looking at their website, it looks like DirectCanada will have stock again on March 25, 2008.

Hi I'm planning to buy either Xeon E3110 or Core2 Duo E8400. Is it compatible with Asus P5W-DH Deluxe Motherboard which I bought last year and still unused.
Thanks for the reply.
Submitted by btuk member. (not verified) on November 3, 2008 - 5:25pm. dual core [as in pentium d]
dual core [as in pentium d] and core 2 are different in the size of die used. dual core pentium d, is 90nm while core 2' e6*** are 65nm, while the newer e8*** core2 series are 45nm. [and in this case e3*** series xeons.]
die shrink is whats needed to achieve lower power consumtion which in turn allows for a cooler cpu which equals a much larger overhead for overclocking. [hence more speed] its not quite that simple but you get the idea.

Hey, what did you guys use to measure voltage? I have a Xeon E3110, Crucial DDR3-1600 Ballistix, and the Asus P5K3-Deluxe mobo (the same one you used in this review). I can't seem to get my Xeon stable at 4GHz. What voltage did you guys use at 4GHz in the Asus voltage settings? I've got a Zalman CNPS9500, it was the largest cooler I could fit in my Antec P190 what with the side fan and all. I've got a super-stable 3.6GHz clock running Prime95 for about 3 days now.

Submitted by Anonymous (not verified) on April 17, 2008 - 6:54am. The Xeon e3110 and the Core
The Xeon e3110 and the Core 2 Duo e8400 are essentially identical, with the exception that the Xeon may undergo more strenuous testing as it is a server cpu.
Any Intel based motherboard that is designed to use 45nm architecture is compatible with both processors, and since memory isn't controlled by the cpu (but by a seperate chip on the motherboard, in the case of Intel)...DDR3, DDR2, etc., isn't an issue. Just make sure that the motherboard you use is compatible with the memory you choose, some motherboards can use both DDR2 and DDR3 (ie..P35 North bridge chipset).
Server CPU's are designed to run 24/7, so the Xeon requires slightly lower voltages to lessen the heat it creates.
The e3110 and the e8400 have identical clock speeds with the same multiplier, but at slightly different voltages (very slight).
I hope this answers several of the questions, these 2 processors are basically identical. Check the specifications for the motherboard you are using or going to use for compatibility with 45nm architecture, DDR2 or DDR3 usage, as DDR2 and 3 standards are also different for each board...but that's a little complicated and I won't get into that.

Well, mainly because the E3110 they are refering to is a Xeon processor, made for servers, supposedly more reliable, longer lasting, etc. The E8400 is a Core 2 Duo, essentially the same chip, but with higher voltages, and possibly more power consumption and heat production.

Submitted by brandon on March 28, 2008 - 12:40pm. Yes it should be compatible.
Yes it should be compatible. I've even seen reports of people using the E3110 on 780i based boards. If the E8400 is supported by that motherboard, the E3110 should have no problems.
And Core 2 Duo is just the marketing name, so since the E8400 and E3110 are essentially the same processor, there is no difference.

the Xeon 3110 is labeled as Dual core not core 2,,,has anyone checked to see what speed they actually show under windows, someone says that a 2 gig core 2 shows as 3.5 under normal circumstances...what does the Xeon 3.0 dual core show.
are they like two 1.5 cores or really two 3.0 cores?

There's the Intel Dual Core and Intel Core 2 Duo. These are only brand names, as BOTH are dual core CPUs. The Core 2 Duo is newer technology, thus better
The E8400 is a Core 2 Duo.
The Xeon E3100 is basically the same chip.

Hi,
on the Intel Website it says that the E3110 only takes DDR2 ram. It looks like your tests here were done with DDR3?
So, does the E3110 work with DDR2 ram?
Thanks again,

To say it over and over.........
If the memory control resides on the same chip , and is integrated with the CPU - then it is possible/likely that there could be problems handling a memory chip with a different way of accessing the lines. AKA AMD.
When the memory access is controlled by a separate chip on the motherboard (that is , the CPU is 'dumb' in this context), all the processor wants is data , and the delivery logic is up to the supplier. It could be construed as the Achilles heel in Intel philosophy ; but commercially works well.

From user experiences I've seen, it works with DDR2 as well. The memory controller is in the motherboard chipset, not in the CPU itself.

Should work with DDR2. After all, if you check the P35 based Intel motherboards like the Intel DP35DP that uses DDR2, you will see the Xeon E3110 listed in the compatible processors. Just make sure you have the right BIOS that will support the processor.
