What are most of you using for cooling?

I am using a $40 Corsair H80 liquid cooler that I bought from these very forums a year ago.

I just bought another $40 H80 a few days ago to use on my 1150 socket HTPC build. Cool. Quiet. Great words when talking about cooling!
 
What kinds of temps do you have on your xeon and what over clocks? some reviews of the single fan Corsairs seemed high under full loading hitting 80C or so..
 
Depends on how much of an overclock you plan to do. I use a Noctua D14, keeps the hottest core under 60C at 4ghz. These chips run pretty cool, compared to their 45nm counterparts.

I got my EX58-UD3R 1.0 and X5675 a couple of weeks ago and while I was waiting for some other parts to come back from RMA, I put together a ghetto testing rig to toy with. The H55 has some cheapo 140mm fan to push and a Cougar Turbine CFT12SB to pull. Since this will be going into a Silverstone GD09, I tested the Scythe Big Shuriken with a Cougar Vortex 120mm HDB.

As you can see, there's quite the difference between an AIO and lower end air. I did try the Big Shuriken with the processor at 3.75GHz and the hottest core got to 86°C.

I will probably test another X5675 in my wife's rig with her Noctua NH-D14 when I get a chance.
 
Great results, much appreciated. I was thinking maybe the 110i Corsair if i did go water to try and keep it cool since i wont have AC but not like Calgary gets that hot :D

But wanted to see if i could save money with an air solution and something in the maybe $70-$80 range would get me good enough results.

That's pretty high voltage for 4Ghz, my x5660 needs 1.25v. Bummer if your chip needs it.

I was a quick an dirty OC and I left everything on auto and just bumped the BCLK up to 160. I'll have to tweak it once I get this system fully built.

don't know if i want that cheap. I guess from some reviews i saw with those, even cooling i7 quads at 4Ghz over clocks they were hitting pretty hi temps...not that i do plan to run it full load 24/7 or anything...

i guess temps in the 70's are not bad full load really.
 
So if i wanted a 970 vid card with this rig, what kind of PSU should i be checking out, 800+?

i think i saw a few in these threads in their sigs with 980's and x5650 and a 600wPSU..

Well i got all the parts...

but not getting anything on the screen with my Asus P6T :(
https://www.asus.com/Motherboards/P6T/

From what i had read this board supported Xeon's from out of the box, not needing a bios update or anything...
Click to expand...

Chances are that the current BIOS only supports X5500 series Xeons and not the "newer" W3600 and X5600 series Xeons. Do you have another CPU to pop in to check and maybe do a BIOS update? If not, the i7 920 or X5550 cam be had for cheap on eBay.
 
Im pretty sure unless someone flashed it to latest bios, you'll have to figure out a way to update before you can go any further...I would help you out but mine (920) went out to a forum member a while back.
 
I have the P6T deluxe v2 and I had to update to the newest BIOS.
I did not have a CPU to flash with so I bought a new BIOS chip off e-bay for 13$
It comes with the newest BIOS flashed, it is an easy swap if you have to.

Neither of the P6T series boards supports 6-core processors out of the box. You must update the BIOS first. You have three options now. You can either borrow an old processor like the i7 920 and perform a BIOS flash or buy a pre-flashed BIOS chip for your motherboard off Ebay, or simply buy a cheap USB BIOS programmer off Ebay, too, and reprogram your BIOS chip yourself. BIOS programmers are selling for like $3, they are easy to use and you don't have to pull out a CPU from your system. If you go this route, you're going to need another computer, though.

Sure. This is the one I own myself and it's been great so far. With this thing at hand any BIOS-related issues can be solved in minutes. Here's a picture of a correct BIOS chip placement position in this programmer.

Very cool do you need to understand any low level programming language, I'm assuming its all hex-edit/binary?
 
For a straightforward BIOS chip reprogramming you just select a BIOS file and click a button to begin the process. It's as simple as it that and neither programming skills nor hex-editing understanding is required unless you want to do some fancy BIOS modifications yourself.
 
Appreciate the feedback everyone, will see which option will work best for me and try it out! Dying to get this rig up and running so having it sit here is annoying!, the X5 series def go for cheaper than most i7 i am finding though.

Would any X55** cpu work?

Will keep everyone posted.

Thanks for the thought primetime.

Thanks for the info. Very cool. Never knew they existed. I could have used one when I was adding micro codes trying to get an X5675 to work on an el-cheapo mobo. I may get one just to have.
 
Got me an i7 920 for $40 from a person locally in Calgary.

Board is booting up so that works fine, has bios v 0603, rather old, updating now and seeing how things go.
 
Bios update to 1408 and BAM!! X5650 works! This means tomorrow will be a day of overclockinggggggggggggggggg
 
w00t! Taht's what I had to do with my L5639 on a P6T standard as well. first put it together and nada. Snagged a 920 from the OP in order to update the BIOS and straight to 4GHz or hex core goodness until she popped :( Be GENTLE on the vCORE.

What was the vCore when it happened?
 
ouch,

i am hoping for 4Ghz stable if i can, i do have 2 X5650's but both the same batch so not sure if they will clock differently.

Going to be reviewing settings today for this and see how well i can do.
 
Okay so , here is where i am at so far.

gear list:
  • Corsair Graphite Series 230T Mid Tower Case, Orange
  • Asus P6T Bios 1408
  • Intel Xeon X5650
  • Noctua NH-U12P SE2 CPU Cooler
  • Corsair Vengeance LP 16GB DDR3 1866MHz Dual Channel Kit (2 x 8GB)
  • HIS Radeon R9 380 IceQ X2 OC 2GB (temp using a 550ti)
  • EVGA SuperNOVA 850 B2, 850W Bronze Modular Power Supply
Using prime95 and blended test, temps seems decent for 4Ghz range. tmax for these from Intel says 81.3c

Bios settings: (everything else on auto)

Doing the CPU/Power test though, temps went high! over the tjmax intel says.

So going to work on lowering the vcore until it becomes unstable i assume may be the first step, i had just used some similar settings someone else had noted they used

Here are some pics of my "table test bench" at my friends place:

K so i just dropped the vcore to 1.28 and upped the multi to 22 with 190 putting me at 4.14Ghz right now, just running prime 95 blended.

I then see the speed dropped from 4.14Ghz to 3.7Ghz, i presume this is because of temps hitting 71C so throttling is kicking in?

i don't think temp has anything to do with it....My multi on my 5670 can only hold a 22 and it looks like on yours it only holds a 20 in fact. So its working as designed;)
Really your only way to get more speed is try and get a higher blck then 190 stable. At 200 blck you can manage 4ghz

Asus Rampage for example i believe has higher multi do to its higher power limit....aside from buying a different board and or cpu...thats all you get:D

Good to know, it seemed like any time the temp hit over 70c certain cores speed dropped, will go back to the 20 / 200 and try it that way, I had disabled speedstep but that drop still happened and the C state disabled as well.

I was hoping to get lower temps on this with the cooler i have, maybe re-check my thermal paste application, as i used the included Noc paste that came with the cooler.

Well for whats its worth the speedstep and cstates (mainly cstates) just lower the cpu speed when its not needed....So you will save a hundred watts or so when the pc is idle,,is all it does...doesn't hurt overclocks or performance in the least:D Not on these boards anyway
 
Good to know, i was thinking back in the day sometimes speedstep would be screwy for stability.

So after 9 hours prime 95 blend test, no errors, i don't like it hit 79C at some point in the night..running in a nice cool basement.

Now i will seldom ever run this guy 100% load, so not too concerned really...

Any other bench's i should run to confirm stability, or is 9 hours of prime95 blend test enough?

I was thinking try and lower the vcore until i find that unstable point to try and keep the least amount of power in this guy...seem's people's results vary in the 1.2 to 1.3+ ranges...

Ram is not stressed at all..

Personally i think you can get it better temps but like you said...it's not a huge deal right now
Is that one of those positive pressure configs on your case? Cause i see no fans blowing out? Your might could add one fan blowing out just to see if it makes a difference. Part of me thinks at least one fan blowing out is good idea
 
i do need to get a rear fan, it had one but i just moved it to the top to see if it helped temps to push air down in front so pressure would be off, this is also with the side panels off.

I reapplied my thermal paste with a drop in the middle vs line down the cores, temps seem similar, i did get the vcore down to 1.25 and am testing now, Small FFTs did better than before, not getting 80+c as i had.

QeoKLJA.png


Let this run and keep pushing it i guess.
 
Well, think i may keep it at 4Ghz with the 1.25 vcore, keeps the temps below 70C on burn in's. This should do the trick for me for now, until i want to push it more and see what i can get.

Want to get some other fans for the case though to help air flow.

After swapping my i7-920 for an x5650 earlier this week on my P6T and running into a similar problem when trying for 22x multiplier, I found out that this is a common issue on the P6T boards, try googling P6T throttling. Effectively the max multi you can use is 20x, when I set 22x myself my CPU speed bounced around between 4.4, 4.6, and 4.0 Ghz but the benches showed practically no performance increase compared to 20x multi as it was sitting on 4.0Ghz under load and the higher clock speeds with no load.

With regards to my own upgrade, I hit 4.0Ghz easy with a 200 Bclk. I feel as though there is more in the CPU, but even with my old i7 I never explored much past 200Bclk, so I'm just going to settle there. Running 1.2875V Vcore and needed 1.3V for QPI/DRAM to get it stable in prime95 for an overnight run. Overall a cheap upgrade for two more cores!

I backed mine down and it's been gaming great for months now without any issues and can't wait to try Windows 10 with it.. temps are fine as I have the cheap Antec water cooler on it with 2 fans and I may see 53c gaming.

this is with turbo clock .

Not bad. If memory serves right 1.33 should get you a nice 150mhz bump higher on the clock. I have the E760 I should dig out and see what it was on last time.
