Kyosen, in fucntion of this post, when you have the time, no pressure ofcourse. could you test that as well the max fsb? i know the board may be limiting but just to get an glimpse :D
thx for your efforts :up:

I also have interest for max FSB.
This board, KFSN4-DRE, has no HyperTransport multiplier setting in BIOS,
so I should be restricted...
...but now I can change multiplier for each core with CrystalCPUID:)

Many thanks to Franck, I've inspired and received hints by chatting with you:up:
I think that I should be able to change NB's multiplier, Vcore, Vnb,
within maximum limit which each CPU product has...not yet tested, though.
K10's IMC will have the clockspeed equal to cpu clockspeed when installed on old AM2 or 1207 mobo;
and it will have its own clockspeed on AM2+ or 1207+ mobo
as you can see kyosen's mobo adjusted NB speed to 1800 MHz - IMC is slower than cpu. Right decision - server cpu has slow memory, so it doesn't need high-speed IMC (667*2=1333 MHz will be enough)
But in Phenom's case 1800MHz won't be enough - dual-channel ddr2 1066 needs at least 1066*2=2133 MHz, so I expect Phenom's IMC will run >2200 MHz and it's clockspeed will be adjustable - manually or auto
ht link speed multiplier.. require ldt_stop.. imposible to change it in windows.. if this chipset doesnt support ht3. it will hold you back..
Are you sure about that? I wasn't aware that any cores had a dedicated part of the L3 -- I thought it was completely shared.
The way I read the Real World Tech article, the L3 latency should vary from core to core if they're all running at different speeds. The latency for each core seems to be dependent on how that core is clocked relative to the L3, but I'm curious about how this shows up in practice.
Now I can control NorthBridge(Integrated Memory Controller) and HT Link multiplier
with good old WPCREDIT, in Windows:)
Yeah, I'm surprised, tictac...but Everest and CPU-Z tell so at least.

And HT Link.
Originally, Everest and CPU-Z are showing different HT Link clock:

F0xC8 modified...now CPU-Z also shows 1000MHz = 200x5!:
http://222.151.153.254/c-board/file/...T_x1_x5_x5.png
F0x88 modified too...nothing occures, but it still works, at least:
http://222.151.153.254/c-board/file/...T_x5_x5_x5.png
And all 3 HT Link can be set at 600MHz = x3 multiplier:

Now I should try max FSB test...but very sleeeeepy.....good night;)
how much for those Opterons?
ok.. i eat my word.. lol.. its only 12midnight here.. come on.. share the might..
kyosen : good work there :) , and thx for sharing to bad you need to sleep :(
no matter, i'm waiting for X4, i was just wondering how much were they going for when you bought them..
Look forward to max FSB test. With the possible voltage mods as well should be interesting. Hats off to Kyosen ( with Mr CPU-Z's assistance :) looks like some interesting results to come.
Shame the initial scores are 10% down on Kentsfield, I was hoping it would be 10% up to take up the slack of not being able to overclock as well. Hmm, maybe on final Spider release it will be about level.
Regards
Andy
Max fsb will be interesting indeed.
Here Phenom reached as much 3.3Ghz already. Although that is on a different platform and seems to be done by multiplier overclocking, I wouldnt be surpised if these Barcelona's had a lot more in them.
"Pictures of AMD Phenom 9600 processor
Pictures of AMD Phenom 9600 processor and CPU-Z screen shot. The name of the CPU is Phenom X4 with codename Agena. It is rated 65nm at a core voltage of 0.976v. The processor is labelled Phenom 9600 clocked at 2.3GHz. The CPU is installed on a NF560 chipset mainboard, that is the reason you see the HT is set to 1GHz. It has 512K L2 cache and 2M L3 cache."
Vcore only 0.976v o_0 Aint that looking good for the Phenom ?

Yep,very low Vcore for 2.3Ghz quad core part :).Where is savantu with his 1.52V claims for 2.5Ghz K10s :D?
This could mean that for 3Ghz,one would have some serious headroom!
BTW ,this vcore is lower than the ones intel specced for 45nm C2Qs at the same freq.
link is busted Det0x :(
thats pretty exciting! My x2 4000+ needs 1.025v for 2.1ghz...they've double the cores and upped the frequency versus the 4000 by 200mhz, and use .5v less. Performance/watt!
This should come in handy for tweaking, if you can find it:

That is very nice headroom for a 2.3G part. 3G and at least one core at 3.3G. I do hope that's not going to be the highest end Phenom that will be comming out this year though. Was hoping for at least 2.6G myself.
I'm thinking the voltage of 0.976V is probably 1.0V rated, sometimes CPU-Z reads a bit off (reads mine slightly low on my opteron 165 as well).
