What's the current Llano APU vantage wr?

[charged3800z24]

Just order the Asus ASUS F1A75-M PRO and the A8-3850 combo. I will see what she does when I get the parts!

[chew*]

Ok, thanks for testing.

I made a "calculator" for Llano a while ago.
This version is a bit censored, but I can send the "unlimited" version for you chew if you like to have it.

This is for A8-A3850 only.

This is odd, OCZ claimed this set has same IC's ( weaker bin )

The 1600 7-7-7 bin is what failed. Possibly SPD is to tight for some timing which is why the set with looser timings is fine.


Here's what the 8-8-8 do at rated volts.

If I pass the 1866 strap with a software OC in windows memory artifacts.



Here's results from that corsair micron set.

couple diff timings and speeds.

with OCZ (no only RAMs) are problems recently....

Well, these are both Black Edition sets, I would say far from recent sets. I must have had them 2 years almost now.

I'm fairly certain that SPD may be a culprit and half tempted to flash the C8 sets SPD to the C7 just to find out.

[The Stilt]

My D9KPT modules are identical to the ones chew has.
Crucial Ballistix customized for OCZ (OCZ logo on the PCB).

I aqquired some new tools so I will have a look if the interleaving modes and such make any difference.

You seeing what i'm seeing Stilt?

Wait what? 2560 and 2576 at 9-11-9-28, in AMD platform

I can bench at 8-11-8 same speed, thats not what i'm showing though.

[TsunamiJuan]

Seems about right, if i didn't have such horrible ram i wouldnt of been limited to 2d's at 170bclk :\ Nice chew

The ud4 seems to be such a superior bclk board right now

The question is, were you benching in single or dual channel? Look close at task manager

[TsunamiJuan]

I was benching dual channel at 908.6mhz 9-11-9-27.

Sorry for being a n00b here, whats makes the single channel vs dual channel special, I know alot of ram out there won't run at 2400 as dual channel (atleast my set won't).

The point is I'm not posting with single channel, the board is skipping something, dropping a channel and booting and reporting all ram is present at bios post, more importantly it's doing it right at 160 to 161 change, to much coincidence for me.

[TsunamiJuan]

Ahh gotcha, I can Try it again in a few days, My ud4 is still drying out from insanity no time to run it tommarow. I'll see if mine does the same thing at 160, i didn't look to closely when i hit 160 just ran lin pack for a few then reboot and threw the multi higher. Though My ram will not clock as high as yours will and run on this platform.

[Barr3l Rid3r]

whats the problem w/ the hyper?

[TsunamiJuan]

For starters they are not my hypers. I haven't spent the time to figure out the voltages needed to get them stable at higher clocks. As for my GTX3's I killed one of them the otherday. When hitting 170blck due to a combination of lack of attention and lack of water proofing.

[Barr3l Rid3r]

I wasn't talking about your memory actually, but I can't see anyone here using Hyper in the tests.

Hypers have issues in 3d, and after I show you 2d with psc......you will throw your hypers in the trash......

[chew*]

Ran some 2d off real quick just feeling things out.







After seeing the 32m result I did some quick math..........very interesting.

Looks like AMD has a new LCC 32m competitor, now if only the damn things scaled frequency well.

1280 7-11-7 anyone

Just LSC and theme for now

[Ccaution]

chew* you blew the competition out of the water mate - those clocks are insane. Grats

I hope we see such IMCs on the BaD boys too

[massman]

Just posting in to say hello to The Stilt. It's been a very long time

Oh, and good work!

[The Stilt]

You seeing what i'm seeing Stilt?

This is unrelated but are you using 2GB frame buffer size in the first pic?

Looks like the initialization of one of the DCT got skipped during post.
I bet if you had measured the memory bandwidth with AIDA64 or so you´ve had seen around 4GB/s drop in the copy performance.
If you manage to do it again check which DCT will be dropped and does it vary. If the memory registers are visible in BCS = DCT0 is enabled, if only in ECS = DCT1 enabled.

Asus boards atleast have an interesting way to handle the memory.
If I insert 2GB sticks in DCT0 & DCT1 plus a EMPTY PCB with 1GB SPD to the DCT1 channel, the system will boot just fine (!).
CPU-Z will detect the memory amount "correctly" (5120MB) but the memory management on Windows only shows 1.5G (with 512MB frame buffer).

[chew*]

1024mb is dedicated to GPU. 2048 not an option.

The rest is lost due to 32bit windows.

I think windows say I have 3072 total installed in the info center normally so 2048 physical minus the 1024mb is "normal"

Yah it's def dropping a channel if you boot it, if you use software it's fine, further more the drop is not even remotely related to stability as we can see by my 2d benchmarks, there was still headroom in memory, Just hitting a hard wall here that drops a channel right after 160.

This post has nothing to do with Llano, but this issue reminds me on my findings with ASUS Crosshair V Formula. There I have a very similar issue.

When booting high reference clock (higher than 345 mhz) with a 1100T and 4x 4 gb i lose memory. 345 mhz is fully stable with 16 gb, between 346 and 355 i can use 8 gb and at 360 i only have 4 gb. CPU-Z always shows 16 gb of memory but task manager shows the reality. The difference to your Llano-issue is that the post screen already shows the real value of 16, 8 or 4 gb. And I can also boot at 345 and change reference clock in windows without loosing memory again. This way I can reach 355 mhz nearly stable with 16 gb (prime95, crysis-benchmark - only linx failed with a bsod).

Is there something going on with newer chipsets?!

[Alex-Ro]

Chew 1280 7-11-7 is awesome.That memory is that?

Today i managed to get 150 bclk by setting almost all drive strengths to maximum.However i can't run anything in 3dmode,it just starts for a second and then it freezes.Just wondering,on air whats the average voltage in order to reach 150 blck for CPU-NB?I tried anything between 1.35 and 1.5 same behaviour.

[TsunamiJuan]

I think i hit 150 at around 1.65vcore, 1.25fch, 2.6pll. I was at 1.8vcore, 1.30fch, 2.7pll when I hit 170 i think.
