xeon w3250 @ 4ghz

[neoguyver1]

Successfully got my XEON w3520 from 2.66 to 4ghz and is stable with 1.312V. This is my first 4ghz overclock with an Intel chip and was wondering is that voltage ok, the chip is almsot identical to the i7 920 D0.

I got a Corsair A70 and put 2 arctic cooling case fans as CFM was close to stock fan spec only spinning @1300 compared to 2000. My idle temps are ranging from 42-48 on all cores and when i stress test they fluctuate wildly from 60-90 even nudging 100 is this normal? Could be less aggressive fans? and what way do ye apply paste to Direct Contact Pipe coolers?

I was using IntelBurnTestV2 on High.

Thanks for your comments in advance.

Volts are good for this chip,but temps are not that good.They are bad .

Idle at low 40c is normal,but 60-100c under load is bad.Had a w3550,at it was 65 to 69 under load(F@H) at same speed and volts,with nh-d14.

Congrats on the OC, but 90C+ is not ok in my books... and yeah server processors are made to handle more heat, so I have heard but still I think the TJmax is 100C so you are only a few degrees from when the CPU start throttling.. And according to Intel the Tcase max is 67.9C I would try running Linx or Prime and if you get the same temp fluctuation there is something wrong...

Direct contact coolers require more thermal past the regular "flat" coolers.. the method of applying is up to you I guess.

Might be why as i usually use the bare minimum when it comes to paste.....i will try a bit more see how it goes!

OK i reseated and i got this i did notice i forgot to put on 4 black washers which i presume are for the bracket on the rear, i did put some metal washers on the front.

Here it is idle just after booting into windows

10 minutes of prime95

So the A70 is cooling her OK i thinks, what you think guys?

I could not stand the stock fans i just stuck these arctic cooling F12 3pin case 1350rpm fans to voltage in BIOS and very quiet if not the coolest solution!!

Perhaps the 4pin F12 pwm version @1700 odd rpm would be better?

I will let heat paste cure for a day and see, i am using a cheap white silicone based grease.It is worth noting Xeons are supposed to run a little hotter thank their i7 counterparts...maybe someone knows more on this.

Gonna try the ugly 2000 rpm fans tomorrow watch this air space!!!

I would strongly recommend downloading Realtemp for temp monitoring sins we don't know what your Intel program (don't know what its called) is setting your TJmax to.. In Realtemp you can set it manually. All temp monitoring software are calculating your core temp by measuring the distance to TJmax. For example: if your TJmax is set to 105C and your sensors are telling the computer it's 50C from TJmax(105C) your temp program will tell you your core temp is 55C. So if your program is setting your TJmax wrong you will get a lower or higher temp from the actual temp on the chip.. In other words there are no sensors telling your computer the exact temperature of your chip, instead distance to TJmax.

Just thought I would share it with you if you did not already know

I was testing the louder 2000RPM stock fans and they are no better than the quieter F12's which will be going back on.

Used real temp here 10'mins into prime blend.

Here is a link to the Intel Burn in test

Idle temps are fine,but load temps are to high for my taste.But its also a corsair A70 you are using.A better cpu-cooler like nh-d14 will handle the heat.

I think i bought it because of a reviewer that put it within top 3 coolers if a bit noisy i don't like the finish on the base i think they should use larger pipes on the inside or all or them, the stock fans are rubbish...i will try some arctic silver or the like see does it help.also should there be that much of a temp gap on the cores i might reset it again but i might wait till i get the silver thermal stuff. Even if the temps are high it is nice and quiet with them F12's.

Is my last night with her i might have a 2.53 hexa core on the way!

Got a brand new oem Xeon w3565 3.2ghz, 3.46 turbo similar to i7-960 for £139 has a multiplier of 24 should be fun!
