Stephen I wonder if you could bump 1 core with K10 stat.

I'm pretty sure that the cpu's were throttled when WPrime took the system info. Regardless, it's not a bad result even @ 1.7Ghz and memory @ 670mhz CL9.

Cinebench score is screwed up. It's only able to utilize 16 cores at a time.

The stream benchmark would be interesting
http://www.cs.virginia.edu/stream/FT...-64_distro.zip

To run it on 24 threads use

Code:

set MB_BIND=yes set MP_BLIST=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23 set OMP_NUM_THREADS=24 start /b /WAIT /HIGH stream5.8_omp-64.exe

AMD claimed an quad socket istanbul system scores around 42GB/s with probe filter enabled vs ~25GB/s without probe filter at 2.6GHz with 2x dual channel DDR2 800.

Here's a dual socket comparison

DDR3 shows some promise in Stream! :eek:

Also probe filter (HT Assist) is working well with all these 24 cores :up:

BTW Stephen can you do comparison shots of S1207/AM3 and this new G32 socket? Can you bent your NDA that much please? :)

Thanks to Franck for fixing CPUZ for me :up:

I don't have another dual proc system set up right now....sorry :(

Oh that was quick, thank you. Guess there is still some room, I assume the NB/IMC is running at <=1600MHz with 1650GHz core speed. The results look like IMC/L3 bottlenecked, can you run with DDR3 at 1066 which should roughly equal DDR2 800. Max possible for DDR3 1333 eight channel is ~85GB/s so this is ~48% efficiency atm, in comparison to ~80% on the quad socket istanbul system with DDR2 800 (theor. max ~51GB/s).
Particle here has an dual istanbul setup, maybe he can run a few benchmarks for comparison. Maybe stream at the same cpu and nb clock speed.

Yes, it would be good to know if K10stat works for this CPU. I have a feelings it will work exactly like it does on Particle's Istanbul setup :(. I think all these server CPUs are hard wired for their clocks and voltages just like Istanbul is. Probably won't be able to overclock unfortunately.

Interesting...never seen that program before, but it does seem to work....at least on one of the CPU's. How do I get it to work on the other?

@ 1800 on one cpu, 32m time drops to sub 6 seconds in Wprime

1024 seems slower

Dunno how to use k10stats for the other cores, but you can use rw-everything to modify the p-states. What have you done in k10stats? Do the p-state-0 modifications work ?

This K10Stat program is pretty cool :D:

I doubt system has populated all memory channels - kinda hard with only 8GB of RAM (unless 1GB sticks are used). Best to clarify ...

s7e9h3n can you clarify memory configuration? How many DIMMs and which configuration (Single, dual, quad channel per socket)?

NINJA EDIT: Just saw 3.2GHz Magny-Cours CPU-Z :shocked::slobber:

Board has 16 Slots...only 8 are populated with 1GB sticks. Will upgrade to at least 32GB in the near future ;)

If you change the p-state-current register with k10 stats it shows what registers and values get written.

You can use the syntax described here by jcool whom used this method to disable the tlb fix on his dual socket system to modify all cores.

Looks great :up: , have you tryied to change NB clocks with k10stats?...what is default core on that sick cpu?:)

Hmm beats me maybe you can assign the program to 2nd cpu with 2 instances open?

Maybe we need a new version with 12 registers :D

When a 965BE shows up at your door make friends with that program ;)

keep it up!!! 12 cores @ 3.2GHz!!!

All cores or just 1/2/3/4. After seeing this, :banana::banana::banana::banana: the Gainsy! Dual MC here i com :P

Any benchmarks @ 3.2GHz ? :slobber:

Thanks for the clue ;)

I found the register and am in the process of editing all 24-cores - this is turning out to be quite an ordeal :p: I need a tool which will script the process.

I'm only changing them to 2Ghz for now just so I can make sure it's stable before pushing this thing hard....

Steve try Wprime v 1.55 please.

Oh and while your at it just snatch up the AMD wprime 32m WR :)

Boot diagnostic mode and run bench 2nd run will be faster usually. ;)

I need to take a emergency flight and bring 2 ln2 pots :rofl::ROTF: it will scale with no need for volts if you run into a board limit. :D
