FINALLY! Barcelona(s) + Asus L1N64......

[yankeex86x]

I have all 64bit OS...
Is there any program able to change the northbridge multy?
If not i'm in trouble....

[msimax]

try this first

http://rweverything.phpnet.us/download.html

[yankeex86x]

Ok the program is working!
thanks for the help msimax!
Now Let's find the target register....

[msimax]

No, I'm running my board with 1GB Reg. memory modules.
I tried 2x 2350 and 4x = 2x + 2x memory modules in this morinng.
My 1GB modules is 1 rank(bank) type, so it looks that bank-interleave is disabled,
but all 4x modules are detected and working:
http://www.oohashi.jp/images/L1N64_K10_x2_memory_x4.png

And here, additional explanation of register mod with MchbarEdit...
...instead of private mail...it's convinient, I think

HT Link multiplier
Target registers are F0x[0E8,0C8,0A8,088].
Barcelona/K10 is designed to have 4 HT Link,
but it looks that one of them is disabled for current K10 Opteron...
...in this case, F0x0E8 is reserved for 4th HT Link, and it's disabled now.
Then, we can observe the value like 80750660 on F0x[0C8,0A8,088] with MchbarEdit.
From AMD's BIOS and Kernel Developer's Guide, Page 146,
HT Link is set as below:
80750660 = x5
80750560 = x4
80750460 = x3
80750360 = reserved (...probably x2.5!? not tested)
80750260 = x2
80750160 = reservied (...probably x1.5!? not tested)
80750060 = x1
We can write desirable value on it, and after rebooting, it should be changed.
# Also we should be able to change HT Link width 8bit/16bit with registers mod
# for F0x[0C4,0A4,084] in similar way, but I've not tested it.

North Bridge multiplier
Target register is F3x0D4.
We can observe the value like C331F024 on F3x0D4 with MchbarEdit,
and last digit (4 in the above case) is NbFid, i.e. NorthBridge Frequency ID.
NB clock is defined as "200 x (NbFid + 4) / (2^NbDid)"
NbDid, i.e. NorthBridge Divisor ID is defined at MSRC001_00[68:64], and it's 0 in default.
2^0=1, so we can think simply NB clock = 200 x (NbFid + 4).
We need to reboot to give effect to changing F3x0D4[NbFid].
# Oppositely, NbDid is changeable without reboot, so the system can reduce NB clock dynamically.

Just to add more information.. with 2 processor install there are 2 Register address need to be set up for both processor to change the HT Link Clock. Which are:

Processor node 0 = Bus#0 Device#24 Function#0 (For processor number 1)
Offset 88h (32bit access mode) LDT Link 0
Offset A8h (32bit access mode) LDT Link 1
Offset C8h (32bit access mode) LDT Link 2
Offset E8h (32bit access mode) LDT Link 3

Processor node 1 = Bus#0 Device#25 Function#0 (For Processor Number 2)
Offset 88h (32bit access mode) LDT Link 0
Offset A8h (32bit access mode) LDT Link 1
Offset C8h (32bit access mode) LDT Link 2
Offset E8h (32bit access mode) LDT Link 3


Here is some guide from me with WPCREdit:
http://www.xtremesystems.org/forums/...&postcount=554

After changing.. REBOOT is required to invoke LDTSTOP_L function and change actual HT-Link

Additional information to access it with WPCEDIT

With 2 processor there are 2 register need to be edit :-

1) Processor node 0 = Bus#0 Device#24 Function#3 (For processor number 1)
Offset D4h (32bit access mode) , Bit 0,1,2,3,4 (5bit)

2) Processor node 1 = Bus#0 Device#25 Function#3 (For processor number 2)
Offset D4h (32bit access mode) , Bit 0,1,2,3,4 (5bit)

NB clock = 200 x (NbFid + 4).
*NBFid = in decimal


Bit = Hex = Decimal = NB Speed calculation
00001b = 1h = 1 = NB clock 200x (1+4) = 1000MHz
00010b = 2h = 2 = NB clock 200x (2+4) = 1200MHz
00011b = 3h = 3 = NB clock 200x (3+4) = 1400MHz
00100b = 4h = 4 = NB clock 200x (4+4) = 1600MHz
00101b = 5h = 5 = NB clock 200x (5+4) = 1800MHz
00111b = 6h = 6 = NB clock 200x (6+4) = 2000MHz
....
11011 = 1Bh = 27 = NB clock 200x (27+4) = 6200MHz

...

I know i know....
but the programs are different so is not the same thing as they mentioned...

[msimax]

[yankeex86x]

I've already donwloaded this program, but it don't work under 64bit os....

[justapost]

Try baredit, should work on 64bit os.

Hey! Then I'm back from holiday. And guess what's waiting on the post office? I'm picking up my ram tomorrow after work, and then there will be some tweaking

@yankeex86x: I don't believe it is your nb that's holding you back. Most nbs can handle up to 2,1 -2,2GHz at stock vcore. Independant core clocking is also supported by AM2 boards, so it's not a ddbt feature

What vcore are you running at?

@Msimax: What? Second RMA in a few weeks? Stop abusing your board :P:

@Tony: Go for it! You can get 2*1gb 667 ddr2 reg/ecc pretty cheap in most stores.

[yankeex86x]

Hi!
welcome back!
You're right....
I didn't understand what locks my CPU from rising up....
I've vCore at 1.26 (the same as NB because there's no DDPM).
I succesfully lowered the NB multy from 8 to 7 and 6 (thanks to msimax and justapost), but the situation wasn't changed.
The 2.32 frequency wall is still there.... and there's no voltage adjustment in bios and software too.
The CPU is almost stable at 2.25 max 2.30.
I think that rams are locking me down so I'll try to buy other 2 modules 2x2Gb to fill the maximum ram capacity (now i have 2x2Gb "only" ) and 4high performance ram heatsink modules like these:

http://www.vr-zone.com/articles/ARCT...asts/5756.html

So I'll be sure that rams won't lock me down....
Any other Idea of what is locking down my cpu???

PS: I didn't understand how AM2/sktF mobo were capable of adjusting core frequencies independently, thanks for the info LIKMARK...

[LIKMARK]

Thanks!

Did you reboot after changing nb fid? If not, do that and check with cpu-z that the nb really have changed. My Phenom 9500 could not change nb fid, downwards (as it is supposed to) or upwards (as is possible with the BE's). Tested it with Crosshair (AM2) and AX78 (AM2+) with no luck.

You probably need to feed your cpu more voltage anyway. Were there problems applying more voltage through bios?

It could be you got a crappy clocker too. Let us hope not.

How is memory settings in bios? Is there much vdroop on the board? (I mean, it IS an ASUS board after all )

Love those ramsinks, were they expensive?

BTW: Would love some bios pics if you got a cam :O

[msimax]

yankeex86x you should run orthos @ 2.2ghz and then start upclocking to see what core borks first. and another trick i use is turn on cool&quiet in the bios with everything on auto except mem timings and what not. now in windows set power profile to max battery now @ idle you'll be at 1.0ghz now use ntune and set it to 235 in 1 to 2 htt steps at a time once and if you reach there load up orthos while using cpuz to check your overclock

[yankeex86x]

I tried everyway....
I think that 2350 B3 Opteron are low power consuption processors.
Phenom processors that runs at 2.3/2.5GHz have their TDP ~100W so i think that I simply need to raise the vCore which will rise up the NB voltage too.
Infact 2350 2.0GHz ~80 TDP while a 9500 2.2GHz phenom has a higher TDP.
Is there a way to rise up the vCore via MCP registry editor?
If is possible.... what registry will I have to edit?
Is there any expert???

[msimax]

did the computer freeze using the cool&quiet method?

[yankeex86x]

No,
I have no freezing with coolnquiet enabled....

[yankeex86x]

Now this is the stage:
I'm still locked before the 230/232 MHz FSB wall.
I changed the NB frequency from 1.6GHz (x8) default to 1.4GHz (x7) 1.8GHz (x9). With the FSB to 225 and NB(x9) I reached NB freq of ~2.0GHz, and i think that i can go much higher with NB...
So NorthBridge is not locking me down...
I tried to fix Core multys to 5 and then rising up the FSB (so the overall CPUs frequencies go from 1GHz to 1.25GHz) but with no luck (so there no vCore limits and no core freq limits defects).... the 230FSB wall is still there....
So, after throwing away NB locks and Core limits my next step was the HTT frequency multy... I could change HTT multy by setting main HTT frequency in bios [200 (x1) 400 (x2) 600 (x3) 800 (x4) 1000 (x5)] but even setting the HTT speed to 600MHz don't help me from rising up FSB speed.... so there no HTT wall... However this motherboards (L1N64 WS and WS/B) have the linkboost capability: The motherboard is designed to have a 25% overall bus frequency boost by default when used with a certified videocard (nvidia 79XX/88XX/9XXX/etc) so we will have enought room to overclock the HTT bus...

Now, after throwing away core limits, vCore Limits, HTT limits, NB limits, the only wall that I can suspect is RAM.
Making the point, I'm able to reach a stable 2.25GHz with a 5:3 ratio and ~750MHz DDR2 Frequency (667STD divider and 12.4% overclock), but I have no heatsink over my dimms and I don't fell safe overvolting them without heatsinks....
As I already mentioned I bought KVR800D2D8P6K24G:
Kingston Value Ram DDR2-800MHz Registered With Parity Dual Rank x8 CaS 6 ECC 2x2Gb
But the system will not boot when setting the divisor to 2:1 (800MHz).
When I'll receve Ram heatsinks (ARTIC RC) I'll try to overvolt ram mudules to see If this is the real wall for my Overclock...

Any comment about my analysis? am I correct?

[LIKMARK]

post memset and cpuz screens of your mem timings

[yankeex86x]

This is all data about my NB chipset Memory timings, memory SPD, CPU and other stuff.... I hope it's enough

[yankeex86x]

I'm also able to set the northbridge at 2.0GHz (x10) (stable) without problems or issues...
but it's not good enough.... I WANT 250FSB!!!!

[LIKMARK]

Just so that you know.. you can open multiple versions of cpuz at the same time :p
Seriously: If you ran your memory at 750mhz at command rate 1t, it might be the limiting factor indeed. It might need 2t above stock frequencies. You tested different mem dividers btw?

Edit:

I'm also able to set the northbridge at 2.0GHz (x10) (stable) without problems or issues...

Do you reboot after editing msr registers? If not you have not really changed nb fid, it just appears so. Only BE's should be able to set nb fid 10, not regular phenoms/opterons. They are hardware locked upwards.

Edit2: example of nb frequency anamoly on phenom: http://www.xtremesystems.org/forums/...0&postcount=28 Look at nb frequency in cpuz...

[yankeex86x]

I tried setting the divisor on 800, 667 and 533...
533 -> no boot
667 -> working ok
800 -> Only a Linux based OS boots up (vista & XP crashes before loading)
The command rate setting is unavailable via bios, I have to se it via Overdrive....
But it changes nothing....

[LIKMARK]

Yeah, changing command rate in windows usually freezes the system too.. Did you see my edit number two in my previous post?

[yankeex86x]

Yes yes.... i see i see.... sorry...
I could change command rate via overdrive without freezing, i changed it alot of times...
I also rebooted after setting the NB frequency to 2GHz and the system booted ok (a little faster) so this motherboard is capable of 2.0GHz NB...
I remember that both Opteron 2358&2360SE have their NB frequency at 2.0GHz...
However I could change the Command rate, and it can be seen via CPUz, but overclock limits are still there....
I'm becaming crazy....

[msimax]

i did it i took off my soldered bios and installed a bios socket from a broken MB i got from ebay 13 hours later i just posted with my old w/s fx bios so my burnt fingers and soldered holes in my clothes was worth it

[LIKMARK]

Wow msimax, now you can change bios from WS to WS/B as you need? There is some dirt cheap 2352's rev b3 at ebay btw.
