What is the difference between the e6700 and the xeon 3070. I have had a look my self but stuggled abit when it started talking about PECI.

I am only a gamer but I can get the Xeon a bit cheaper but I was wondering if that it would be worse for games.

The 3070 is just a higher binned e6700. The clocks and cache are exactly the same, but the 3070 will run cooler and usually will overclock slightly better. It is never guaranteed because every CPU is different. But since the bin is higher this will most likely be the case.

So if you need the coolest running Conroe you can get, the 3070 would be your choice.

No idea but these processors are identical in spec except the xeon will be the "better quality" part so to speak.
Server components are assumed to be in use 24/7 so the requirements to "make the team" are slightly higher.

If you can get the xeon version cheaper get it. Usually they are more expensive. You are lucky ;)

If anyone is interested you can get them from here.

That equates to $370 USD... Newegg offers them for $349.00 in the states.

However, the E6700 C2D is going for $323 USD currently. Things are a little different over here. :wink:

channels I can get it though make it a bit cheaper for me. but the stuff in the stats is cheaper ther in the UK

Hmm... accept Mercedes... and how much do you pay for healthcare over there??? :P

Reply to PCAnalyst

Hmm this a good thread because I had my mind set on the 6700 but if the X3070 is better I would like to know too :)

xeon, then build a custom phase change/chiller or get someone at xs to build it for you, you can build one for as little as $100 if you build your own evap, or for I'm guessing around $200 if you get someone at xs to make the evap for you and braze it to the cap tube before hand since that's the hardest part :D

What about standard 775 heatsinks? Will they fit with the Xeon? Will they perform as well with standard ddr2-800? If so I might get one of these myself instead of an e6600.

Reply to MonocleCat

Standard hsf works fine, but I would go aftermarket or water/chiller/phase for extreme overclocking. Any ol' ddr2 will work, but check out crucial, they have a massive sale going on their top end 1000mhz and 1066mhz chips. You will lose roughly 5-10% with ddr2-800 instead of 1066 though

Reply to I_Love_Tacos

Already picked up a pair of crucial ddr2 1000 1gb modules during the last batch of price slashes on newegg. $330 something msrp.. I got em for $150. <3 newegg I'll deffinitely go with this chip then. ~$10 more than the c2d equivelents and Xeon sounds much cooler :D

Reply to MonocleCat

That's what I was talking about, and they go even lower for the standard editions, the lighted ones cost around $140 though
Here's their 1066 kits

The regular is just $130 8O 8O 8O 8O 8O 8O 8O 8O 8O 8O 8O 8O 8O

You're making not buying a 2nd pair very hard for me Tacos.. I'm trying to save up for a new pc here you know! Damn, that price is insane... Must... not.. reach... for... debit card.....

Reply to MonocleCat

lol, you minding sponsoring for a phase changing I'm building while you're at it? I could make a second one for you if I am able to get it down right and have the time....

Reply to I_Love_Tacos

Would love to, but my room gets so hot in the summer, my case would probably have a foot deep pool of condensation at the bottom after a few hours. :lol: Though I don't plan on running the rig here untill I figure out a better cooling situation. Good luck with the build though, make sure to post some pics.

Reply to MonocleCat

I will, but don't expect them for another couple of months

I wouldn't worry so much about condensation because of the way it works, so when it's well insulated, the most condensation you would get is probably on the cpu die itself, as if you insulate correctly, the backside of teh mobo and the vrm shouldn't freeze, though it would be nice to consider phase changing a nb to just see what the max fsb of the p965 chipset is :lol:


Tell me more about what you're planning to do with your new computer's cooling, I can probably be of assistance there, I tend to know a thing or two in that area

Reply to I_Love_Tacos

Just to be sure, the xeon conroe is supported by any board that supports socket 775 right? Most of them don't list it in their 'supported processors' specifications.

Personaly I don't because I just go on Nhs but I have heard it being about
£40-60 a month for 1 adult and 2 children.

Reply to kickme21

That has sorted it I will go for the Xeon 3070 heehehe.

I would still love to know what the hell the PECI is on Intel stats for the C2D

If the chipset supports Conroe, then it will support a Xeon Conroe. :)

Sorry to give the company I work for a shameless plug but you can get E6700's for cheaper than the Xeon 3070 you've linked to :)

Even for an increase of £10-15 I think the Xeon sounds like a better option. The link was just an exsample of a company the sells it at not a bad price. Sometimes depending on if you have an account with those guys you may get it cheaper.

That's what I would do, the xeons run with less voltage, meaning longer life and cooler running, plus as I already mentioned they will oc higher too

Depends on the OC you're looking to pull off. A couple of °C isn't really worth the higher (unless the price is only $20 different like when I bought my 3060 to $40 higher) prices. You don't really see the benefits until you start doing extreme overclocks, where ever MHz and °C counts.

Edit for typo

Reply to dasickninja

Perhaps, but I find when the price difference was so minimal, the xeon would have been the better choice, though if I recall correctly, only the regular conroes were affected by the price drop, so now I would say e6700 over 3060, but at the time the price between the e6700 and 3070 was about the same, then I'd say it was a no brainer for an ocer

The Xeon's have also gone down in price also.

Reply to 306maxi

In that case, xeon would be the smart choice, I hadn't checked up on the xeons in a while, so I wasn't sure

Reply to I_Love_Tacos

Xeons are inferior to Core 2 Duos for single user operation. Not only are they more expensive clock per clock, but they do not perform as well for single user scenarios. I am of course talking about the Woodcrest version. This topic seems to be refering to the Conroe version, which I must admit, just sounds like a marketing ploy. I think the only real purpose to the Conroe version is that by having the name Xeon, people think theyre more stable. Are there any studies that show this to be true?

Reply to gentrinity

They are higher binned, the voltage requirements they have to pass to be xeons are higher and so because of their ability to run at lower voltages just as stable, most oc higher using the same amount regular cpus do at lower clocks. Kinda the same reason why enthusiasts would buy opterons instead even though they costed more because of the better oc ability, that, and the fx cpus for bragging rights, but that's beyond the point

Reply to I_Love_Tacos

Ok, that makes sense. The conroe versions are then a good purchase. The Woodcrest versions are not, I think we can agree on that.

Reply to gentrinity

Of course, the woodcrest xeons were based off the netburst architecture, and we don't even need to bother considering those anymore, even the lowest clocked am2 opterons would spit at even the higher clocked woodcrests

Reply to I_Love_Tacos

I wouldnt go so far as to say that.

http://www.gamepc.com/labs/view_co [...] 800&page=1

I would say that clock per clock, they perform just about the same, with a very very small nod going to Conroe. However, Conroe has one distinct advantage over the Woodcrest and that is the DDR2 memory, which is designed for single-user. Woodcrest uses FBDIMM memory which is great, if youre running a server, but not so great when you are running memory sensitive applications, such as Winrar.

Reply to gentrinity

Bah, the woodcrest servers ran hot and couldn't beat the amd counter parts even with higher clocks, they were based off the netburst architecture, and because of that they were a complete failure. The reason why the k8 cpus couldn't compete is because flat out that was an ancient architecture, it was designed for .13u, meaning tons of performance loss once you get down the 65nm if you don't come up with ways to reduce transitor loss, and also it's been around since 2003, the core march is flat out the better one simply because it uses newer technology and implemented performance:clock AND high clocks, a problem amd is having because they don't want to get off of SOI since they don't want to spend the money researching

Reply to I_Love_Tacos

Intel have only steoed upto the pace of AMD in my mind for gamers. For a company the size of Intel is pritty poor. Just feel sorry for AMD after all that hard work and starting to progress in market share they are now loosing out to Intel again. I would rather be talking about an AMD now but I am now going to buy an iferior CPU. Will be first Intel build for me.

I am definatly an AMD fan boy but as I say not so much that I buy an inferior CPU.

You guys did that one a while ago, I remember dario was still around back then

And am I the only one that thinks this new look sucks horribly?

Man, thg is slowly turning to sh!t, first the cpu forums, then the gfx, and now the site's image itself

Reply to I_Love_Tacos

Meh. You'll get used to it. I just want them to change the code to fit widescreen. It looks scrunched now.


But I digress. Speak about this in the Structure section.
