What's the current Llano APU vantage wr?

[Barr3l Rid3r]

I don't got it, chew just put some Hypers to work at 2000Mhz 7-7-7 with everything on, gave up and went for micron again?

They are crashing beyond that as are the microns..........

Latency plays little role here. Speed matters most.

Looks like its time to ditch hypers for 2x2GB kits and go for whatever good PSC is left...2x4GB is gaining in popularity and I've been seeing myself having issues with 32-bit OS and 4GB lately...mostly due to bloated OS though.

2200 8-10-8 (smth I would hope my 1600 C6 can do if 2200 C7 are not in stock when I get a chance to buy) vs hypers 2000 7-7-7, what wins? Hoping for future IMC improvements like we saw with Deneb C2 > C3 and C3 > E0 X6, would even 2100 7-7-7 be worth it anymore over an insane PSC freq Hypers can not hit?

Well I know that hypers can be capable of 2500mhz 8-8-8... would it beat 7-10-7? I guess so...

2500 8-8-8 in what?

valid.........aida 64........

I've yet to see it in 3d especially on the UD4 I have.

Please show me the error of my ways.

I set the setting back up to 8-8-8 2250 ( the rated of sticks ) after that 2000 run, same crap in the video.

hard lock all benches.

Maybe you have not been reading what people are saying and only seeing what you want, but hypers needs more volts than most sticks at high speeds. I'm not cramming 1.8 in mine............

Pretty sure Barrel is talking P55, and validations as far as that goes. Especially the ADATA and STT kits, doing 2500 8-8-8 valid at 1.85-1.9v is far from impressive...lol.

Hypers would rock if they were tolerant like Micron, however they are not

[The Stilt]

Did some BCLK testing today.
After some "debugging" and testing I found couple of things.

Before I was stuck at ~158MHz BCLK or so..
Currently benching at 176MHz BCLK and still testing
I haven´t even touched the timings, dividers or voltages yet.

The internal GFX is enabled (naturally) just like every other integrated component.
The APU is running quite hot (around 50c in load) so I´ll might try it on water too.

I´ll post the specifics tomorrow.

[Alex-Ro]

176 BLCK on air.Oh boy...

[The Stilt]

I´ll say that the high BCLK "issues" (if 75% overclock can be seen as one) are either clockgen programming or "strapping" related.
In clockgen programming there isn´t any obvious faults tho

I think Asus resets certain frequencies (PCI-E, PCI, USB) at certain pre-programmed BCLK frequencies.
The software straps (timing latch) excist only up to 110MHz BCLK... I guess they did not think anyone would go higher...
After that the timings remain the same, only the delays are calibrated.

It was quite a rumble to find the correct sequence:

1. Set the BCLK to 161MHz, save and exit.
2. Enter setup again, set 166MHz BCLK, save and exit
3. Enter setup yet again and set 170MHz BCLK, save and exit...

EDIT: Forgot to mention, in case the system crashes for any reasons and it does not post straight away, you need to start again from step 1.

Going higher probably requires on the fly adjustment until we get a bios with GPU clock control

Yeah I know, for me 155MHz BCLK works, so might 156MHz. 157,158,159,160MHz fail..
161MHz start is the key The frequencies between 161MHz and 166MHz fail too, yet 166MHz works.

In case the system boots but crashes or freezes when Windows has been loaded, bump up the VDDNB a bit.
This is because the SCLK and UVD clocks raise too... Even without 3D application running the clocks can spike up temporarily which will freeze the system as the SCLK and UVD are too high. On A8-3850 the SCLK & DCLK will be at 1020MHz, VCLK 1224MHz when the BCLK frequency is 170MHz.

It is a lot easier to reach high BCLK with a locked APU on Asus.
In case the APU is unlocked the CPU must be able to INIT at ~5.3GHz.
Thats because Asus is using reduction divisors (/2) with <23x multipliers...
This means the CPU inits at 32x170 before the reduction divisor kicks in.
Thats why I had to start alot lower and watch out for cold boots.

[G.Foyle]

Lots of good info I'll be checking those tips soon.

[Alex-Ro]

Thanks to The Stilt,managed to get superior blck and IGP clocks,due to interleaving.Previously was capped at 147 bclk with channel interleaving.

[veblen]

Glad I caught this on the bot's twitter feed; it's chock full of useful information - thanks guys!

I'm an amateur and spent the last two days trying to bench my rig (A75M-UD2H/A8-3850) after giving up a month ago.

Here's what I have right now at 121x29, 968MHz @ 9-11-9-27MHz (GSkill ECOs):

CPU PLL: 2.6v
CPU Vcore: 1.5ishv (went all the way to 1.58 but it didn't do anything for stability at higher BCLK)
CPU NB: 1.4v (went all the way up to the max but it didn't do anything for stability at higher BCLK)
APU VDDP: 1.35v (just how high can I push this? Is this the GPU's vcore?)
FCH: 1.25v
RAM: 1.6v

The system boots up to 150BCLK x25 with memory speed around 1000MHz but will not run any 3d benchmarks without rebooting.

I tried enabling and disabling dual-link DVI and setting the GPU freq manually to 600, 750, 755, 800, even 900 without success.

Am I doing this all wrong? I'd appreciate any suggestions!

Set the GPU frequency to 400MHz in bios.
With 150MHz BCLK frequency your GPU (SCLK) will be at 600MHz which is the stock frequency.
This ensures that the fault is not the GPU.

Thanks The Stilt! Going to try it right away!

Edit: I tried setting GPU frequency to 400MHz and am unable to boot into Windows at 150x23, 1999MHz @ 9-11-9-27. Does this indicate a problem with my GPU?

[The Stilt]

What happens if you set it to 450MHz (675MHz)?
Or 480MHz (720MHz) / or 514MHz (771MHz)?

[|ron]

Did some testing with the A75-M Pro mobo with Stilt's bios... it gave me a little boost in ram scaling.
The problem with that mobo is that I can't set gpu freq, or at least I don't know if it's possible.
Anyway, my latest two results, ln2 just finished and I couldn't go any further!
Gpu at 986mhz, multi-test fillrate in 3dm06 is around 19k.

Broken 1800 at 11


and around 310 at unigine


It's the best I could do until now

[The Stilt]

You can only overclock the GPU by raising the BCLK on locked APU´s.
Overclocking the GPU with a bios control will never work since the maximum SCLK (GPU) frequency is limited (product specific).

[The Stilt]

Did a quick high BCLK & SCLK test on the "expendable" chip I had to bolt on today.
I was testing high VMEM voltages today and did not want to fry the ES chip so I threw in a A6-3650 instead.

The NB on 3650 clocks better than the ES with single rank memory but with double rank memory it is even worse than the old ES.
Anything above 920MHz NCLK seem to be a no go.

This is a qualification sample (same stuff sent to the reviewers) so I think the retail chips are atleast a bit better.
And they nearly always are.

Broke my "tools" so could not go above 170BCLK

The performance sucks indeed due low MEMCLK / NCLK.
In theory the next MEMCLK ratio (1333MHz) should be doable, but I guess the DRAM Phy goes too high (so it ain´t working)...
At 170BCLK it would be at 6.8GHz.

[The Stilt]

Broke 8k in 06 with the A6-3650.
175MHz BCLK is not a problem and 177MHz is fine too for GT-1.
It seems to be all about the NB temperature so this thing could fly once in sub zero.

The bandwidth seems to be quite ok too.

The integrated PCI-E devices will be lost at 170MHz BCLK+ (= PCI-E).
Disabling all of them (Audio, LAN, Asmedia USB3) makes the 2D artifacts go away.

No artifacts in 3D even when they are on thou.

[chew*]

Looking good stilt, I'm failry sure your IMC will wake up once you go even slightly subzero.

I had Dry Ice over weekend but was testing "other" stuff so no time to see if I could gain anything.

I would not expect to gain much on other ends (gpu clock) (cpu) however from phase.

[chew*]

Just a thought stilt

Core disabled tricore I take it are about to get released.

I'm less interested in unlocking cores but that chip denotes we can "disable" cores via bios.

Can you look into that for me? It's a feature that imo should be already there and isn't.

[The Stilt]

None of the available boards have this feature.
Not even Sapphire, which otherwise has the best adjustments by far.

The base bios has some internal node (0-3) information, but thats it.
Nothing to configure the CpuEn values.

Dunno if even Armorhead has this option.
With PGRA option it could be easily done thou.

Surely you can configure them on the fly, but the system has tendency to crash if you do so

[El Gappo]

A higher strap at the base clock would be interesting.

Got some evo two's arriving in the morning Hopefully better than the Ripjaws.

Any idea what the highest ram clock is on llano so far?

Well over 2700. No sense in claiming records on Llano though

I dunno, I always thought you thought of them as a high score instead of WR :p

Why not show us some more chewonthis* magic before you leave?
