Intel Xeon x3440 ?

[INFRNL]

I had my X3440 up to 4ghz, but the mobo fried. I think 4ghz will be easy, but not sure how much higher it would go. 4GHz is fine with me from 2.53.

I am using a Megahalem RevB; comes with the new universal intel mounting system, but kind of expensive$60 plus shipping. very nice cooler and worth the money IMO.

The 3440 is the first of the p55 line to have HT. I bought mine for $234-8% CB=$215.28. Can't be beat for the price unless you buy a 920 from MC for approx $215 after taxes

EDIT: off topic, what mobos you guys running? My UD2 bit the dust because of my stupidity(did not put heatsinks on the pwm mosfets I think thats what they are called); I would like to stay under $150. I am trying to buy from a local store but limited and most seem out of my range. For a $150-$200 board would have been better to go with a 920.

for $150 I can get UD4 micro or asus P55D
for $170 I can get evga LE or P55D-Pro.
or suck it up and wait till mid week and order online? END Edit

Thanks for your answer, now i have a i5 750 but im thinking move to X3440 to reach easily 4 ghz and the plus of HT, i have eVGA P55 FTW nice lay out

[INFRNL]

Thanks and good luck with your build.

The FTW is more than I spend on my 920 rigs. I might try the LE, but not sure yet. I might need sli for gpugrid, but not neccessarily. for now i will only be running 1 gpu till I get more money and upgrade the PSU

You re welcome , in my opinion is better option one gpu and you spend more to upgrade to better psu like Corsair 850HX

OK, waiting feed-back about your coolers ... however if we compare your chip with this 860 (cooled by a CM TX3):



your vCC seems to be a little higher ... but your Ts are better ... maybe you can put your vCC down or not?

I might be able to drop vcore down a little more... I'm still trying to get a feel for the voltage behavior on this new rig. How much VTT were you using?

@darthcani: I still can't use the (x20) turbo multi with my setup. It sure would be nice to have for trying to get to 4.0 and I'm not so sure that I would want to run the voltages needed for 4.0 24/7 on air. I think running 4.0 with hyperthreading is a more diffulcult task to achieve than 4.0 on a i750.

Here is a quick prime shot at 3.8 using a TRUE cooler with push/pull fans. Voltages had to scale quite a bit for the additional 200Mhz.

Have you considered the GIGABYTE P55-UD4P (~$170)? I think a good power supply section on a M/B is well worth the extra $ spent especially if you are going to overclock.

Do you remember how much voltage you were using to get 4.0?

These Xeon CPUs sound interesting. Here's a comparison table from the Intel Xeon Processor 3400 Series - Specification Update for anyone looking to get one.



When C3/C6 is enabled in the bios, an X3440 can step up to a 22X multiplier when a single core is active. (2.93GHz / 133MHz = 22).
By comparison, an i7-860 has a maximum multiplier of 26 when only a single core is active.

When not using C3/C6, the i7-860 might be an easier overclock with its default 21X multiplier compared to 19X for the X3440.

[KURTZ]

agreed Uncle, but i think is correct compare a X3460 with the 860 processor ....

[unclewebb]

Where I live, the X3440 is priced between an i5-750 and an i7-860 but it's closer in price to the i5-750. An X3460 is a little more expensive than an i7-860.

It's a nice way to get Hyper Threading if you need it without having to go all the way up to an i7-860. Before today, I didn't realize NCIX have some of these in stock.

[KURTZ]

yes is really difficult find out these chips ... i bought it in Germany ...

1.19

1.184 vcore and 1.19 vtt for 3.6...
I think your chip has better overclocking abilities then mine. I don't think I could complete a 1hr. prime run with voltages that low. I may explore lowering my voltages some more at 3.6 but I think it will error out.

How about trying 19x200 with your setup? I'm also curious to know the batch# for your proc.

Looks like its a nice batch!

today is arrived my X3460 (batch L920B580) what's yours?

My X3440 is batch# L920B451

damn, i think that the my chip is weird like yours ... :S

Having trouble with the turbo multi? If so you may have to wait untill ASUS releases a BIOS that officially supports these Xeon procs.

what troubles do you have? (i've the same M/B than you)

I saw that your previous screen shot with the i7 860 showed an ASUS Max III Formula? I can't get my turbo to work stock or overclock... mine are all locked at 19. Your seems to be working. What did you mean by your chip being weird?

[KURTZ]

bad overclocking dude ... i mean this ... bad voltage and bad temps ... i bought this chip cause i think that are better than the normal i7s ... but it seems that isn't ...

Well our batch# are not that far apart... however your particular i7 860 does seem pretty nice.

So what were your BIOS settings for the 32M superpi... I would like to try/test them with my combo?

nothing special, i've just assembled with stock heatsink ... it's all default ... i'm waiting for a new block in the next days so after that i can do something ... check my Ts with the stock cooler ... just ridiculous ...

Here is mine with the BIOS set to "optimized default" settings...still showing no turbo...

[KURTZ]

@ Roger: do you have enabled the turbo feature in the bios? it's strange ... really strange ... we have the same family chip, same os ... have you asked to eVGA?
