Llano in the house... (as Charged :-) )

[Stuen4y]

@FlanK3r, are all the wprime benchmarks on win xp? I managed to do higher frequencies than you but I think the stupid win 7 is holding me back on some of the benchmarks. I will try sub zero room temperatures if it gets colder (I hope I haven't missed the last chance), today I benched only on 11 degrees ambient temperature as it got from 5 to 8 degrees outside... The 3870 gets extremely hot with high clock and voltage, mine wants 1.58V for best results on short tests and aroun 1.56V for longer tests. My previous Phenom II X4 940 wasn't that hot at 4.1+GHz. I have all the benchmarks I've done up in HWBot, but I'm too lazy to upload them all. I forgot to redo the validation, too, so I haven't made my last call.

[FlanK3r]

yes, wprime are better in XP. Wow, looks, u have nice chip, I can not higher than 3750 MHz hard benchmarks....

also a properly setup Vista can be pretty efficient in wprime.

Hi Flank3r, excellent benchmarks. Just curious, but have you tried using IntelBurnTest/Linpack to test 24/7 stability?

In my experience with F1A75-V Pro and 3670k, CPU Throttling will occur when one of these conditions is met:
A) Core Temp temperature exceeds 70C, which is also Tj Max. Asus AI suite reports 45C when Core Temp is about 70C
B) TDP Exceeds 120W

I suspect this is what is happening to you that is causing your benches to be slower once you overclock higher. I've tried getting around this by disabling all power options in BIOS.... cycled through all BIOS revisions starting from 0605, to Stilt's custom bioses, to the latest builds available... no luck . I can't seem to prevent throttling from happening... it seems to be built into the chip and can't be turned off. The one app that repeatedly makes my Llano throttle is IntelBurnTest. I know it is only a synthetic load and not indicative of real world apps, but the fact that it makes my Llano throttle bothers the crap out of me. It pretty much means that you can only bench single threaded or lightly multithreaded apps when using a higher OC. I am not even using built in graphics, but I suspect a game like BF3 places a more realistic gaming load than Futuremark apps to test for 2d+3d throttling.

The highest 24/7 stable result I can get that passes IntelBurnTest/Linpack grilling is 3.6GHz @ 1.5125v. Any higher, it exceeds both TDP (as measured from a Killawatt) and Temperature (I am using a Kuhler 620 in Push/Pull). For what its worth, I think the concept of a system on a single chip is great, but its still not priced right. I am lucky I was able to score the F1A75-V Pro for $60 on Amazon slickdeal, and another $100 for my A6-3670k. FM1 was fun overclocking, but the hard throttling limits preventing 24/7 use is a letdown. Sucks... FM1 was never meant to be a overclocking enthusiast platform. Regardless, I am replacing my daily driver/gaming computer with this until I make this a HTPC. Will stick around with this as my main PC until PD rolls and future incarnations come around

It can be due to the better cooling the Gentle Typhoons I use for benching are monsters) but the chip is crap for 24/7, couldn't even make 3.6GHz and the maximum frequency at which it passes Cinebench 11.5 was around 3.6GHz too with the 24/7 setup. I was even considering buying a second TY-140 fan for the TRUE Spirit as the default one might not be enough. Its memory controler is very good though and the gpu is very good overclocker. I will try the 3d benchmarks on open window with cpu around 3.7GHz. The chip's really strange as it needs a lot of voltage to get high frequencies and is very very hot. I don't have a discrete graphics right now and I think that with the IGU disabled it can probably overclock a bit more but that's about the limit of the platform. I don't belive all the reviews stating their samples are rock solid at 3.8GHz, that's not possible or the just the reviewer's samples are very carefully chosen ones.

I've never seen trottling on mine 3870K and I bet that with the IGU at 960+MHz with 1.37V and 1.58V on the CPU at 3700+MHz it is well above 200W.

[Miwo]

You try using IntelBurnTest Stuen4y? Its very possible to not throttle but it depends on the game/bench load. Use Core Temp + IBT.
I can SuperPi all day too at 1.58v @ 3.7+ , but its not a large enough load to induce that throttling. As you said yourself, you were having trouble above 3.6GHz for 24/7.

Using IBT on VeryHigh, I am pulling about 250W on full 2D load across my system. Of course it varies by PSU efficiency, and other components you might have (I am using discrete). But definitely check out Core Temp if you can

[Stuen4y]

I'm usually stressing the cpu with prime95 64 bit or OCCT 4.0 but using the IGP its the best to test real games or 3DMark 11 combined test for stability as things change when both the cpu and the gpu are stressed. I agree SPi isn't anything demanding (its 1 thread only). I'll try coretemp and IBT for the 24/7 settings and will post the results. Things really change when you OC all the parts - bclk, memory controller, gpu and cpu so my 24/7 will be slightly lower than people using discrete (why to buy Llano if you plan to use discrete graphics, but ok). How do you measure that power, using some kind of software or using a wattmeter? If it's the first option don't rely on that measurements.

[Miwo]

I bought Llano because I got both cpu+mobo at good prices, otherwise I agree - it doesn't make sense if using discrete graphics. I'm coming from a 720BE, so regardless it is a step up for me. My plan is to move the Llano to HTPC using integrated graphics after my next PC upgrade and see how Trinity, PD do.

I am reading power off a Kill-a-watt meter, but Asus EPU Probe also reads it for the processor. According to the software, its just around 120W on full IBT 2D load before throttling for me. My Killawatt meter reads about 250W under 2D load due to the other components I have in my system aside from the LLano

[The Stilt]

Best stability & maximum heat test for Llano: Run Prime95 LargeFFT and OCLHashCat MD5 or SHA-1 brute force at the same time.

[FlanK3r]

But...this is unrealo world...I think, prime 95 blend for 1h is OK for clasic daily use.

[GeorgeStorm]

I've never seen the point of stressing cpu's so hard, just test them in similar conditions to you want them to be stable at that speed for, applies to all levels of overclocking, want it just to run cpu-z, then I'll push it as hard as I can just so it can do that, even if nothing else, want it stable for daily use, then I'll stress is as hard as it will get stressed in daily usage, no point in pushing it harder.
Currently got mine sitting at 3.5Ghz @ 1.4v Haven't tried lowering the volts etc, may have a bit of a play this week actually.

[Stuen4y]

That's not 100% true as you may use you pc say 3 weeks without restarts with multiple sleeps or so and you will have trouble even from this if the system is not 100% stable.8+ hours prime95 is more like the basic load for daily stabilit. If you want to be sure that the system cannot hang, ever, the time starts to get measured in days.
P.S. Does anyone have this problem when the pc sleeps and then after wake up its extremely slow. No matter if its oc'ed or not?

Best stability & maximum heat test for Llano: Run Prime95 LargeFFT and OCLHashCat MD5 or SHA-1 brute force at the same time.

I'll try the combo. I've sent you a private message and wrote here in the thread. Could you please give a link to the latest modded bios for F1A75-V EVO, please.

WOW!!!
Very impressive man.... Gives me more hope for Trinity.

Hope you show some benchies, stability and ambient results with that gem in the near future.

Gratz on that sweet silicon bud!

Really good indeed!

Over 2V on 32nm is a bit scary but I see you have no fear at all namegt

Do you have this new bios for the F1A75-V EVO? I'm desperately looking for a better bios than 1601 for my MB. It's quite buggy with the profiles and sometimes changes voltages when I use offset voltage for 24/7 (the only way I can use the power saving features).

[FlanK3r]

...:-D Thx for rent Froxics RAM modules

[Stuen4y]

I'd love to try modules like that... Great results, @FlanK3r.

[FlanK3r]

first place ...I think, in future going up with this score...maybe 22 000 points

[froxic]

...:-D Thx for rent Froxics RAM modules

No problem my friend. They can do 7-11-7-26 35 T2 @ 2460Mhz with 1,915V (Geil EVOTWO 2000 C6 / PCS IC)

I just benchmarked Athlon II 651K and it was 1MHz precise same as my result with two 3870K. All three CPU are from 1151PGT batch. So I just little bit dissapointed. I made some wPrime runs to show "stable" heavy workload...

- Llano IMC is very nice
- using onboard VGA out = no bus o'c done

[Stuen4y]

Try with loose timings of the memory, frequency helps much more than tight timings, especially for the IGU. Are those frequencies stable? What's the cooling?

I've put another TY-140 fan on the TRUE Spirit 140 and the temps are down about 5-7 degrees, so I'll try higher voltages and I hope I'll be able to stabilize higher frequencies.

I don't know if I've mentioned about the problem with the vertical lines (more like gpu artifacts from very high gpu clock on a discrete video card but without the polygons and different colours) that flash through the screen on every kind of not intense 3d - flash (webpages), windows aero, etc. The problem appears only after several days of usage without restart/shut down and happens on 100% stable clocks - both at 820 and 870MHz of the GPU with everything up to 1.26V on the gpu (I'm in the process of long term testing when (if) it will disspear with higher voltage, lower voltages didn't help). The system is rock solid stable, tested both on syntethics (prime95, occt, furmark, 3dmark 11 combined test loop, etc.) and long period (3+) of played games Crysis 2, Skyrim, Civ V, Age of Empires 3 (may look stupid but it's pretty demanding on 1920x1080 all max), Starcraft 2. The temperatures were about 50-54 degrees after several hours gameplay and now don't climb above 45-6 degrees. I've tried changing the drivers and have tried 11.12 and 12.1 but without luck. On default that isn't observed but I'll never use the system on default and the memory on lower speeds than 2133(now it's 2170 but it's stable up to 2200, I think even 2220 is not a problem).

[MacClipper]

Presently using the onboard VGA so no going for higher RAM speeds without bus overclocking.

So far, this test rig is stable in short runs of LinX, SPM and long runs of Skyrim/Syndicate gaming. Probably end up as a surfing and casual gaming HTPC in a tiny ITX box so not going to bother with crazy hours of stress testing.
