I have a supermicro h8qgi-f with 2 x Spicy 6276 @ stock.
I have 2 sticks of 1600Mhz ram at CL8 for each cpu, each stick is 2GB so each CPU has 4Gb and the whole system has 8GB total.
Debian stable.
The Kraken installed.
Xorg killed.

8101:

Does this look normal?
Would getting 4 more ram sticks and going quad channel improve the TPF a lot?

Rough estimates --
23m23s with psmax 1 trick (forced 2600 MHz, requires PowerNow to be enabled) -- you shouldn't really be pursuing this given you can OC these chips
26m26s at stock (no turbo engaged)

You're at 25m-26m so it seems ok... (little to no turbo).

Make sure to add Kraken as well (mind updated instructions for V7 -- http://www.amdzone.com/phpbb3/viewtopic.php?f=521&t=138463&p=224042#p224042)

Not sure about gains from going quad-channel, I always go with optimal config.

In two DIMM/socket config make sure that each node gets memory, i.e.
Node 0, DCT 0
Node 1, DCT 0
Node 2, DCT 0
Node 3, DCT 0
 
Someone correct me if I'm wrong but are Interlagos 4-channel? ie - Shouldn't you run 4 chips per CPU (start from furthest socket: stick, skip, stick, skip, stick, skip, stick skip. The socket next to the CPU should be empty.

Depends on mobo design though, about RAM placement. It will run if you do it wrong, just won't be as fast?
 
For max performance, used quad-channel mem configuration. However, they do support dual and single channel configurations.
 
Yeah, it will work in single, dual, and quad, should work in triple.
The more chaneles the faster it should be.

Can sombody test Tri channel? That would make it easier on my wallet to get more ram and upgrade to tri and then quad later.
 
It might not "see" triple channel? Check the RAM map first. It might see them, it might not. It might go single channel x 3 and slow down.

I've put 3 sticks in a mobo years ago and it only "saw" two of them. It would see 4 though.

Note these CPU's are 8/12/16. Intel x56xx goes triple because it's 6, and quads have the same controller?
 
OK, I just looked at an ASUS 2x 6276 system running a 8101 WU, stock everything, DDR3-1333 speed, quad channel setup. 22:30 TPF. Looks like you are taking a big hit somehow.

Channels are always separate (unganged) on AMD G34 platforms.
Some Tyan boards allow ganging (which, nb, is unsupported by AMD on these platforms)
but it doesn't offer increased performance -- at least not w/FAH.

Anyway, per your nomenclature, it's always "single channel x1", "single channel x2" , "single channel
x3" or "single channel x4".

I prefer and recommend using vendor's nomenclature:
1. An AMD G34 CPU consists of two nodes
2. There are two DCTs (DRAM Controllers) per node
3. Which gives total of four DCTs per package
4. Each DCT typically handles one to two DIMMs (4/8 DIMMs per package)

If in doubt, run tpc -dram for exploded view.
 
As a point of reference, I'm just getting my first G34 4P setup with 6282-ish (2.6GHz, 3GHz psmax 1) and my TPF on the same work unit went from 11:33 to 11:10 by going from 2 DIMMs per CPU to 4 DIMMs per CPU. These are server-grade 4GB ECC RDIMM 1.35V 9-9-9-24 timing.

Anyone know if disparate memory timings is a concern? Main timing is the same, but second line is different. Two DIMMs per socket have the first timing; two DIMMs per socket have the second timing.

Code: 
Node 0 ---
DCT0: DDR3 frequency: 1333 MHz
Tcl=9 Trcd=9 Trp=9 Tras=24 Access Mode:1T Trtp=5 Trc=33 Twr=10 Trrd=4 Tcwl=7 Tfaw=20
TrwtWB=9 TrwtTO=8 Twtr=5 Twrrd=1 Twrwrsdsc=1 Trdrdsdsc=1 Tref=2 Trfc0=2 Trfc1=4 Trfc2=4 Trfc3=4 MaxRdLatency=60
LDIMM0=OK/OK LDIMM1=EMPTY/EMPTY LDIMM2=EMPTY/EMPTY LDIMM3=EMPTY/EMPTY

DCT1: DDR3 frequency: 1333 MHz
Tcl=9 Trcd=9 Trp=9 Tras=24 Access Mode:1T Trtp=5 Trc=33 Twr=10 Trrd=4 Tcwl=7 Tfaw=20

Spazturtle, did you/can you verify that Kraken is installed properly? (top reports
thekraken-FahCo as folding process).

Your TPFs flux a bit too much, I think...

While you look at "top"'s output, see if there are other CPU-consuming processes.

Also, while in top, press Shift+T to sort processes by cumulative CPU time -- could
provide some hints as well.

[and make sure to verify DIMM layout with tpc -dram as suggested before and,
perhaps temporarily, run tpc -psmax 1 (note that it doesn't persist across reboots)]

"top reports thekraken-FahCo as folding process" Yup

thekraken-FahCo uses 3196% of cpu
thekraken-FahCo, FahCleint, fahcore_a5, top and init are the only things with over a minute (seconds? The Columns aren't labeled) of cpu time.

Had some issues finsishing the wu, aparently its a known issue with ext4 journaled.

have yet to install tpc.

I ran "tpc -psmax 1" whist fah was running and I suddenly stopped being able to connect to the client remotely.

Do I have to stop fah before oc'ing?

On production CPUs this should always be safe. On ES, it may or may not, depending on how "well"
the P-states were defined; it _should_ work, however.

Run tpc -l and show us all p-states of one core. What is the part number of your CPUs?

Would "tpc -set core all pstate 0 frequency 2600" be better? (or would it be 2600000000?)

Look there: http://hardforum.com/showpost.php?p=1039116320&postcount=7

Remember:
psmax 1 -- enable PowerNow/CPB/Turbo.
manual OC -- disable PowerNow/CPB/Turbo.


Also how do I stop and start fah v7 from debian terminal.

I don't support V7, sorry. It's just too much pain to work with...

Both CPUs are ZS232245TGG44 Family 21 Model 1 Stepping 0

Inbetween the file not found errors it said Maximum pstate is 6 and the startup pstate is 0
Using tpc 0.43 as 0.44 wouldn't compile, something about a svn error.

Also for tpc when entering the freq do I enter it in Hz or MHz?
 
Ignore svn error. Though make sure that binary builds ok (sudo make install succeeds).
Install ncurses-dev package prior to building 0.44-rc2, if you haven't already done so.

What Ubuntu version are you running?

Frequency is in MHz.
 
Using Debian on kernel 2.6.x
Ok I'll try installing that package tomorrow as its an ungodly hour in my time zone.

Though if you recommend I can always wipe and go to Ubuntu server.

Thanks for your continued help and support.
 
Debian should be fine.
The issue with not-tested distros is that we can't always provide bit-exact instructions...
 
No idea why or how this works, but have you tried running a small (cheap) PCIe video card instead of the server chip?

I got a huge boost from running a $19 ATI 5450 instead of the integrated video.

Could be wrong, but it's worked on Supermicro, Tyan, and ASUS server mobos.

Might be my imagination.

Sidebar, IMO, Ubuntu 10.04-64 GUI is the easiest to run. Plug and play GUI with no trash added. Like Windows XP except fast.
 
Not using a GUI, I didn't originally have a card (5850) in the board but the board wouldn't boot with the card in, it may be that the card has some damaged pins on its pci-e connector though

I was thinking of one of the passive cooled 5450's as the integrated gpu is very slow.
 
WARNING! :D (a little late, but what the heck!)

I'm clueless about server boards. Until recently, I never "played" with them, I just set them up to MFR spec and fired them up. Then I bought some serverboards dirt cheap on Ebay and started playing with them a few weeks ago. First thing I learned was the docs aren't always correct, and "dead" mobos often aren't...

... and that server boards aren't as friendly as desktop boards.:eek:

I saw problems when I first installed a PCIe video card in a SuperMicro. But after pulling the power plug then plugging back in, life was good. Keep the power off until the mobo LED dies completely, count to ten, plug back in. You need to drain the capacitors of both the power supply and the mobo.
You might even have to do it twice. My Intel board is really touchy, I avoid HW changes like the plague.

Another thing, is on one of my ASUS boards, it HATES nVidia. Dunno why. I have never had an issue with nVidia on any other mobo.

And last but not least, for some reason certain HDD's, DVD's, and USB devices can interfere with hardware recognition. Keep a PS2 (round plug) mouse and keyboard handy for troubleshooting.

If your computer won't wake up / respond, try plugging in a PS2 keyboard before you shut it off. I've had to do that several times already, but my KVM switch is USB and "adapters" don't always work on serverboards. I haven't found one that does yet.

Each Interlagos CPU (at least for the 12 and 16 core models) has two NUMA nodes, so it's got 2 dual channel memory controllers. The overall effect isn't much different though. You still want 4 sticks.
