Not only is there multiplier bugs there is ref clock bugs........ref clock thinks it's changed but it's really not so some of those uber ram clocks and WR's some are claiming are BS. The program is being tricked.

Going to have to wait till software reads these parts correctly.

Avg clocks on air/water = 3600-3700 all at stock volts to.

Phase IIRC i tested around -40 on ln2, got you to 4.2 ish stock volts.

Avg ln2 clocks = 5000-5200 at 1.7v........higher pissed off chips also the jump in volts was only to gain 200 mhz.......cold scaled more than volts.

Avg ref clocks are much lower on many boards for boot making some of the speeds people are posting unrealistic for a 24/7 bootable rig.

Max avg ref clocks are 125ish unless we some some great strides in bios's, symptoms you will find booting high, lost HD in boot.

Thanks for your sharing chew*

Nice chew*, thanks for share this info.
Any word about fGPU overclocking with this unlocked part?

IIRC with stock voltage 1100 was doable.

To push the IGP you need to increase the CPU_NB voltage.

My boards/cpu's are still in transit, will go over some quick stuff on LLano as soon as it arrives.

llano under-clocked to 1.13v

AMD_A8_Undervolt_CPUZ.jpg

hmm interesting

this is also kinda funny and cool....not much Intel can say about that

You might have noticed that we used an seven year old Thermaltake K8 Silent Boost cooler, originally designed for first Athlon 64 processors. We deliberately used the oldest AMD heatsink we could find to demonstrate just how upgradeable AMD's ecosystem is. Even though the company changed seven processor sockets (754 to 939, AM2, AM2+, AM3 and now AM3r2 and FM1 for Fusion), you can use the identical heatsink at default clock.

Im thinking, 1.4V in reviews is too much and maybe its a BIOS problem.

Black Edition chips will be needed to see real potential I guess.

if there would be a BE i would sure buy one... right now i am not so sure the system compatibility with higher ref clock above 125 tends to worry me a bit.

(actually i will buy for kids but that is for general systems which won't be touched OC wise, just with some decent ram)

**Barr3l Rid3r** · 07-06-2011, 10:30 PM

My thuban sits at 3200mhz 1.12v when under 20% load...no big news on it, I just wanna know if those Llano are good Hypers clockers and if we will be able to turn off or lock the multiplier of the APU in a near future.

SandyB only can do about -0.15v at undervolting test, i3 only save 6w with -0.15v undervolt,

i3 2100

i7 2600k
http://www.computerbase.de/artikel/p...t_undervolting

looks like Llano have huge power saving potential if you manually tweak it.

Just got the ASUS F1A75V-PRO from the local store
I have run few basic test and here it is ( no time for OC yet ... )
bug_.jpg 3DMark06_7202.jpg

SUMO 9640 ????
GPU-Z can't get the name right
and TMonitor doesn't work with the CPU

Test Platform

AMD APU A8-3850 @ 2.99GHz
ASUS F1A75 V-PRO (BIOS 0604)
Team Xtreme LV Series DDR3-2000 2GB X2 @ DDR3-1666 (CL9-9-9-24)
Integrated Radeon HD 6550D ("Sumo 9640?" )
AMD Stock HSF ( It have the same stock cooler as Phenom II X2 555BE )

Windows 7 SP1 32bit
Catalyst 11.6 Win7-32bit

Hello Flank3r
The Retail version I got have same 1.4V Default VCore
I don't know if it's normal , but I think the processor can work with 1.35V instead
dunno why AMD bump it up to 1.4V

**imamage** · 07-07-2011, 07:21 AM

BTW , any driver and tools good to recognize APU GPU/CPU Spec other than CPU-Z / GPU-Z
It acts weird in my test platform

**Nintendork** · 07-07-2011, 07:51 AM

BSN power consumption is totally botched. Even anandtech review's points a stock powerconsumption for cpu load of 123w(1.4v) and that what BSN achieves with heavy undervolt (1.13v)...

http://www.anandtech.com/show/4476/amd-a83850-review/9

Yes, another epic fail for BSN.

In resume

Total system
BSN A8-3850 cpu load 1.42v 184w
BSN A8-3850 cpu load 1.13v 123w
Anandtech A8-3850 cpu load 1.42v 123w

Some Actual clock speed testing versus some of the BS results being posted.

The only relevant thing here is cpu score.

**Barr3l Rid3r** · 07-07-2011, 08:20 AM

1600 6-7-6? What's going on in here? I Tough it's going to be a very good Hyper clocker.

C'mon Chew show us some impressive numbers.

**mattkosem** · 07-07-2011, 10:20 AM

I received my F1A75-M Pro yesterday. The nic seems to die after receiving some amount of data though, so I've not gotten much benching done yet. I may just throw in a PCI-E nic and call it a day instead of dealing with RMAs. None of my SSDs nor my HDD seem to be recognized any longer once I increase the base clock. I've only tried 108 so far though, so hidden dividers that are mentioned in some of the new reviews coupled with a higher base clock might help there.

The SATA controller seems to perform somewhere between my M1015 and SB850, with most of the advantage over SB850 on SEQ reads (which seem to get past 1200MB/sec on A75 where they didn't go much past 1100 on the SB850).

**FlanK3r** · 07-07-2011, 10:45 AM

Chew: whats chip is it? Some A6? Really so hgigh CPU clock? Score looks real...(phase cooled?)

**Manicdan** · 07-07-2011, 11:15 AM

in the note on the desktop for chew's, i see -190C right?

The point of those screenshots was not to chase down good scores.......ES chips + WR = fail on anyone that claims thems behalf.

There were only a few goals, find clock limits, find out what the multi limit was if there is one. Find out if there is cold bug. Find out how scaling with voltage is.

My hardware is in limbo, almost all of it.

None has returned from it's trip yet......even if I wanted to show something I can't. Thats not hypers btw.........

Also like I stated, some of the high ref clocks/ram clocks being posted may not necessarily be "real", things are still to buggy atm........ people are showing 160+ with 5.9+ gig......laughable

The voltages users are reporting are indeed correct btw.......HL = 1.35ish. LL = 1.4ish

Chew may I ask which driver you use ??
Catalyst 11.6 ??

chew* · 07-07-2011, 07:55 PM

TBH I'm not sure it was some beta that was provided on a disc.

I was honestly not concerned with gpu performance.

I installed the driver comes with the Retail version , it just show "SUMO 9640" in GPU-Z and in CCC as well
I guess Catalyst 11.7 will fix that

**Alex-Ro** · 07-09-2011, 01:28 AM

Go some results too,seems like while ahci enabled i cannot oc at all,if s-ata set to ide,a whole new story begins.chew,does any other voltage than cpu vcore and cpunb matter?there are another 5...

That's exactly my experience with it too. AHCI and Raid don't work properly once you get past 105Mhz or so. AHCI mode shows the drives on the post display, but they don't appear in any OSs and RAID doesn't see anything at any point. I've pushed as far as 133 on IDE mode though. Will try more later when I have a chance.

**Alex-Ro** · 07-09-2011, 08:57 AM

Maybe someone guide us on how to obtain high mem clocks?I got good PSC chips capable of running 2300+ stable,but everytime i pass 2250 i somehow get errors and instability.I increased cpu-nb to 1.35 but no go,which of the other voltages make a change?

There are:

1.1 VSB voltage)1.1-1.2 range
1.2 APU voltage 1.2-1.8 range
VDDA Voltage 2.5-2.8(CPU pll,shoudn't make much difference)

i only need to push a little bit the vNB (1.45v works great) and Vdimm (1.7v)
