X58 + i7 930 adventures

[ashishmishra]

Just as another point of reference my 920 D0 needs 1.32V for 4.0 w/t HT On. Corsair H50 with push and pull config pushing out of the case (Coolermaster 690 Gen1) maxes out at 85C with all of 12GB RAM used for testing. IMO 4.0 w/t HT is the more practical limit with HT and I think that you have run into the practical limit without HT.

BTW sick setup as usual n7, but your SSD subsystem definitely is the highlight of the entire pc.

I've verified lower than 0.7 readings with contact method as within instrument tolerance. Now if you're shooting mirror finish...

heavily depends on material and the instrument being used. The primary problem of the "cheapies" is focal distance moreso than fixed emissivity.

Yes one can figure this out with experience and above all common sense.

I've used some of the cheapies that fit on a keychain. The thermohawk is one of my favorites. Nothing fancy, no laser, short range. But it's excellent at finding hot VRMs on boards. I'm talking the ones that start to smell - this little devil has saved my skin - literally.

IMO it's an accessory that no techie should be without. Instantly you can read your temps around the cpu socket and the back of gpu boards. May not produce EXACT pinpoint results but certainly beats touching it with a finger and saying yeah it's a little hot!

The other thing touching circuits running at multiple ghz can do bad things for the circuit AND you.

LIR is also nice to see the big picture but can look alarming to those without electronics backgrounds and knowledge that certain areas and components are supposed to run at given temperatures. Comparing pictures taken over time will tell the true story, however.

I've been running my 930 @ 4.2GHz with HT on and 1.45V (1.411 at load). It's been 100% stable. 200MHz faster than the 920 D0 I had before it.

Should've got that E5630 Xeon

Very nice!
Air too?

No such thing for sale in Canada.

 

[nyker96]

excellent chip, oc very well. but you need to get better cooling probably full water loop to keep down the temp at 4,3.

 

[PUN]

is it safe to run these at 1.45v?
Mine is at 4.1 HT on @ 1.31v (1.344v on CPUID) C0 stepping.

 

[Rubycon]

Once you cross 4.2GHz at 1.4V you will find that (non water) solutions are hard to keep temperatures manageable. What I mean by manageable is within TJ limits of throttling! Unless your room is cold or you keep icewater around your radiator (H50), there is no free ride.

Not sure about long term at 1.45V as I've never run one that high based on what I just said previously.

Some claim to run 1.45 and higher at 4.4GHz with high end air like a Megahalems or VX. I think their definition of load or stress is different than mine.

 

[AdamK47]

Yes, the CoolerMaster V8. It runs very very hot. In the 90s.

I've dropped the voltage down to 1.375 (1.35 load) for 4GHz. The temps are now in the lower 80s at load. All temps reported using RealTemp.

I use V8 also.
My temps are in the low 80's as well.

HAHAHAHA, common sense? Where can you find that here?!? ;-)

Those laser ones drive me insane. Trying to instruct people ages 60+ on their proper use when they are months (if not weeks) from retirement and explaining that the temp doesn't come from that "little laser dot" but an average of a "spot size" is like standing in a hurricane expecting to remain dry......

No such thing for sale in Canada.

They've "Launched" according to intel, and tray prices are out and everything, but it looks like availability is running about 3 weeks late.

They'll be out to buy soon.

I don't mind the laser since I know what its purpose is.
It makes a good pointer when you need one too!

I turn them off on our hand helds when we send them out. If they are smart enough to read the manual to turn it back on, hopefully they'll be smart enough to read what it is used for.

...The main problem w/ HT for me is that i found going from the no HT of the i5 750 to the HT on w/ the i7 860 gained me nothing but higher temps.
I don't do anything that utilizes 8 threads, so for gaming, the higher clocks are preferable to lower clocks w/ more threads...

Precisely.
I just tested out an i7-860, and ended up turning HT off to get 4.0 stable at decent
temps, and I ended up with, effectively a higher clocked i5-750 with my "crippled" 860.
HT does seem simply to add more heat.

 

[Apocalypse23]

n7 made some foolish impulse buys over the last couple weeks, & the result is pictured ahead. ^_^

Gigabyte X58A-UD3R
Intel i7 930
HIS HD 5870
Corsair H50
A bunch of other stuff too, but less exciting...

I've been running a Gigabyte P55-UD3R + originally an i5 750 (4.15 GHz) & more recently, i7 860 (3.9 GHz).
While i was extremely happy with that, i was getting a bit bored with it...

Some pics of the new toys.

While the SATA3/USB3 is largely useless to me presently, the 10 SATA ports + 2 eSATA is delightful, as i run a LOT of HDDs over various systems.

I switched the H50 fan out for a couple beloved Noctuas (exhausting out).

Batch is B: 3938B268

I quickly discovered X58 is annoyingly more difficult to OC than P55, particularly regarding higher speed RAM, due to the precise calculations needed surrounding QPI speed + uncore speed + RAM speed.

I have a lot more to learn, & will work on lowering voltages, etc. more as i have time.

Below is the latest results i've gotten.
HT is indeed off, as i've found i do absolutely nothing that benefits from it.

4.3 GHz (HT-off) 1.3v BIOS w/ LLC level 2 enabled

Question to n7 and other Gigabyte X58A-UD3R owners:

Is it possible to quad crossfire on this board since it has 4 pci-e x16/x8 slots? The specs state "tri sli/tri cross" support.

 

[Rubycon]

I wish more mobos had 4 pin firewire right on the back like that!

 

[n7]

HyperThreading on results aren't very exciting as temps hold me back as usual.

Nice even numbers though.

Got the RAM's primary timings tightened up, & w/ a bit more vDIMM, i can actually do DDR3-1600 7-7-5.
Not really worth it though.

4 GHz (20x200) 1.275v BIOS (actual ~1.25v)
DDR3-1600 7-7-6-24-1N 1.6v

 

[OILFIELDTRASH]

Temps too high for my liking. One word...megahalems.

Working on my 4.0ghz right now but I'm needing 1.318v in bios HT on. Max temps are 80c on hottest core and I'm gonna reset my heatsink cause I think it will do better.

 

[Anubis]

nice N7. mine wont run at 4ghz with HT on with that low a voltage, max temps under LinX look good as well, i would have figured the H50 would have been able to keep them a lil cooler then my VX but all in all a nice OC you have there.

OILFIELDTRASH - running a Mega or VX isn't gonna drop him below 80C under linx with that OC, slightly lower but they aren't miracle workers. mine peaks at 82C

 

[n7]

Yeah sadly my chip seems to be a pretty hot one.
Pretty huge temps difference w/ HT enabled.

I wouldn't bet on that...I am running at 1.3 vcore (1.2 under load) HT on, and I never go over 64c with my mega. Now I am only at 3.7, but I thought it was more about vcore than speed. Water may transfer heat well, but my radiator can dissipate more heat than an H50.

 

[OILFIELDTRASH]

OILFIELDTRASH - running a Mega or VX isn't gonna drop him below 80C under linx with that OC, slightly lower but they aren't miracle workers. mine peaks at 82C

I had to actually up the voltage to 1.325v in bios now due to stability issues, HT on, and I just reset my heatsink with AS5 so it still needs some burn in time. If my chip would do 4ghz at 1.275v in bios I would definitely be mid to high 70's without a doubt.

Megahalems ftw.

The H50 is over 10C warmer than the VX. Of course this is at 4.4GHz / 1.32V HT ON (W3520). The difference between the coolers really spreads when you turn on the heat. Stay at 4GHz or lower and the H50 is fine - LinX load included.
