I have recently, through an Intel program, picked up a qx6850 for $275. I bought a new motherboard, ram, case, DVD drive, PSU and built myself a new PC.

Intel QX6850
GA EP45T-DS3R Mobo
2GB of CL7 DDR3 1333 OCZ Ram
OCZ 600W PSU - StealthXStream http://www.newegg.com/Product/Produc...StealthXStream
P180 Antec Case w/ 3 120mm fans


Few things:

1) With a Thermal Right Ultra 120 and an Antec 120mm fan I'm setting core temps at about 38C-42C at idle and 60C-67C at 100% load. This normal? I used Arctic Silver 5 paste and spread it with an old drivers license. Current I changed the multiplier to 10 so it's running 3.33Ghz instead of 3Ghz.

2) My 12v reads 12.xxx in the BIOS but in windows it reads like 2.x at idle and 8.x at 100% load. I'm using OCCT to stress the system. What's up with that? View the attached file.

3) I want to run it at the 11x multiplier, but the system turns off when I try to benchmark it. It boots into windows fine though. Could it be voltage? What do you guys suggest? View the attached file.

 

Shouldve bought a MAC

 

Yeah right!

 

i dont know much about overclocking, but when u up'ed the multiplier, did you up the voltage as well?

 

It's gonna reboot when you push it to hard to save the cpu/northbridge/southbridge, and other vital systems.

What are you gonna be using the rig for?

 

you buy a mac for two reasons...... ya like ****, or your a mongaloid retard. either way MAC = FAILDOZER

 

MACs have their uses... and I don't need a MAC. Besides, I could easily install OSX if i needed it.

I'm going to be using it to process pictures and possibly get back into gaming on a PC, but nothing major.

I just wanted to OC a little cause I can. I haven't touched the cpu voltages for 3.3Ghz, i've read it's fine. I think I do need to up the voltage to use the 11x multiplier.

Just wondering where folks temps are.

At idle my system is Declocked to 2Ghz due to Intel Speed Step. It's totally automatic.

 

dude...... As far as gaming is concerned, only 2 make use of quad core technology..... If your already at over 3ghz.... Leave it. More then enough power. As long as your fsb is over 1333mhz.... And you have a decent gfx card(I.e. Nvidia8800gts) you'll be cool. Don't run vista, unless it's 64x.

Maybe pump up your ram to 3ghz.... That should get yamoee then enough fps for gaming.here's the brass tack.... Build it for gaming, and everything else will run like stig....

 

You should probably invest in liquid cooling if you are going to be pushing those kinds of numbers.

I have a Koolance 750watt diffusion system and I over clock my system past the 15% mark and never see temperatures rise about 39 under a full load.

Your temps are either getting too high or your voltage isn't stable I'm not experienced with OCZ however, but I would let it run overnight and record voltage levels for a base reading then stress test and record them again.

If you see a lot of voltage spiking you're system might require a more stable (read: not more powerful) PSU or you can get a voltage conditioner as the spikes may be caused by your home power line.

Good luck!

 

39C on the cores?!

One thing to remember is that I have a quadcore, and it's the now older 65nm, so it's TDP is 130W... It's going to be hotter than the newer 45nm Quads and less than the any of the dual cores.

any info about core temps being ok though? I've read as high as 100C is ok for these, and other places as high as 64.5C. I know that CPU temp is about 15C less than the core temp, since the core temps comes right off the diode.

 

No, not 39C at the core that would be nice, but sadly no.

My chip is an 939 socket AMD 64 X2 Windsor 6400+ 90 nm SOI so my TDP is up there around 120-130w.

But still, liquid cooling has so much a higher potential to for heat management than air.

It's worth it to look into it.

 

Whats your core temps at idle/load?

 

I'd have to go home and run a check on the cores, the probes read:

CPU: 22C~39C
MB: 36C~41C
VGU: 23C~28C
HD: 18C~25C

These readings are using Everest Ultimate Edition - I believe they go off BIOS but I am not sure.

 

damn those are ice cold.

I'm running stock cooler on the ATI 3870 and it's like 50C idle, lol.

My HD are about 3x

Thanks for the info.

 

I know a little bit about OCing... First thing you should do, if you're system boots, but fails to start windows. Bump up the Voltage. OCing is all about trial and error, much like modding a car. Just keep playing around with the voltages until you find a value that's stable. That's what I did.

On the other hand, you don't need liquid cooling unless you're really trying to churn the most out of your CPU, your setup seems to be fine, but you need to bump up your voltage a little. I have almost the same exact setup, but my parts are probably a year older (rebuilt last year).

I haven't checked this in a LONG time, but my temps are
~49-55 C on loads
~mid 40s on idle

A little warm for my taste, but my computer never crashes, only on super ridiculous hot days it crashes ...

You also might want to check your air flow. Make sure none of the air is colliding. Typically, with your cash, i'd let air suck in through the back, and air sucked out in the front. Also, be sure to check that your fan speeds are set to high if you think you're CPU is hot. Finally, I'd recommend changing your heatsink, the Zalman cooper ones are much better. Copper heatsinks > steel-looking heatsinks (I forgot what material they are)

I'll update this when I can
