AMD dual socket thread

[LIKMARK]

Hi yankee! I'm familiar with bar edit

About the 266MHz problem, I find it strange, I had it running once totally stable in dual channel mode, it might be a fluke, but I do not believe so.

I have tested a little further, and can boot into windows with 266 memclk mode, but not stable yet.

It might have to do with channel clock skew, but there is quite a lot of options. I have only tested the extremes yet. My theory is that the board/bios chose the right level of channel clock skew the one time I had it stable, it was set to auto setting at the time.
I just need to find the right setting again.

Also.. Enabling tristating seems to give better stability with 266 mode (seems to, mind you )

I also thought about Clock screw and i tried a lot of choises but we have almost 18^4 choises ... considering that every bank of channels have 18 choises....
I had no luck....
You are right about the tristate mem clock set, it increases the overall stability, but it's not enough to make the system usable (even bootable).
Let's find a way to solve this issue...

That MSI Speedster board does look nice. In fact, it looks a lot better than Asus'

Personally speaking, I dislike AMD's server solution due to a factor which is that AMD does not have their own inhouse chipset for sever boards. Well, they do have one now but it is not widely used. Majority of Opty sever mobo uses Nvidia chipsets which put out a lot of extra heat. (Which seems to be what Nvidia is good at... Inefficient chipsets.)

Does that MSI board support s1207 opty B3 out of box? Or does it need BIOS update?

[LIKMARK]

It needs a update. I like the extra ram slots yes, wonder how the Speedster II performs. *checks out google for tests*
Edit: Found.. nothing..

hey karbonkid i dont see any oc options for right now

[LIKMARK]

this is what I emailed:

Hello.

Here is a list of non-functioning/missing bios options on bios 0501.

FSB/HTT clock does not change when set to other values than 200 in bios.

There is no voltage control in the current bios, these need to be unlocked/fixed.

The following voltages should be user defined: vcore cpu 0/1, vdimm, vnb, vsb, cpu 0/1 overvolt option.

Memory clock 266 (DDR2 533MHz) causes bluescreens when applied, probably because the current bios for this board sets too tight memory subtimings.

Memory timings need to be unlocked so that these can be changed by user, this includes subtimings.

Cpu multiplier should be user defined (up to max supported by cpu, example: 9,5 multiplier for Opteron 2347)

HT link frequency for processor # 2 shows as 200 wich implies HT link multiplier of 1 instead of 5, wich it should be.

NB frequency is set to 1400MHz by default wich implies a X7 multiplier. The right multiplier used should be 9 (or 8?) for NB frequency 1800MHz(1600MHz).


Thank you

PS: Is there a new bios under way soon?

The current bios is very bad for such an expensive board.

Regards

Christian

I suggest all fellow L1N64 owners do the same, then they might take it seriously, and we might get a bios wich ain't crippling performance.

so when if anyone is going to get a GTX 280 to see what it pushes with two AMd quad cores ?

[LIKMARK]

Probably less than one higher clocked phenom I'm afraid. Have not tested 3dm06 yet, but opened the app and it only listed one cpu..

[alucasa]

Power of DP system is in rendering and crunching (= Folding / WCGing) for majority of us.

Gaming on DP system is likely less impressive than a single processor with high clock. When 8-hour render takes 4 hours on DP system, one knows what to go for.

I got a pair of Opteron 866's in the mail yesterday

ZPV866FKA6BS
FCBNE 0442TPAW

They run at (AFAIK) 2x2.2GHz, so they're equal to the 875's, except that they're quite old. I wonder what CPUZ will report when I try them.

*waiting for my K8N-DL...*

Posted these benches in the Nehalem thread in NEWS section, comparing Barcelona against Nehalem ES, not holding up too bad IMO.

Yankee: Got the solution for memclk 266. It is easy, too easy for spotting it at once as it was very obvious.

Trfc is set too tight on memslot1. It is set to 75ns, and needs to be higher (105ns works fine for me). So as long as you can boot into win, wich is doable if I enable tristating and disabling rank interleaving.

This is a problem with many boards, especially the Abit AX78 wich I had earlier.

One "not so positive" thing: Clockgen freezes my system if I try to increase HTT by 1 above 250. Then I need another way of overclocking beyond 250HTT

[xPliziT]

LIKMARK, those are fantastic results

This is a dual barcelona setup right?

Must be otherwise my phenom @3.3Ghz results are crap

Especially your multiprocessor speedup with 7.xx blows noehalum away

[xPliziT]

gotta add my truecrypt bench also

thanks

Low clocks with probably tlb patch enabled on cpu2
It is dual setup yes.

Nice truecrypt btw Much higher than core2

[xPliziT]

Thanks too

checkout my quickPI thread and add your results please

the problem with clockgen is it doesnt work when the 2nd cpu is installed

nice work btw keep it up

ok I didn't know.

Thanks

Ok!
If it really is the main problem i'll try to edit the SPD data inside the DDR modules to make them use this setting automatically....
I hope to not burn anything...
Why didn't (auto)manual set it to the loosen value???

[LIKMARK]

It is one of the biggest problems with K10 and ram compatability both for socket F and AM2/AM2+, strange that mb vendors have not fixed it yet.

Good luck flashing SPD Let me know how it works out for you (Then I'll have to do it myself too, if I dare )

[yankeex86x]

I tried every setting in bios but I'm still not able to boot to desktop with
266 mem divider to change the trfc...
Now I'm checking if it is possible to change the SPD flash rom via Vista x64, otherwise i'll have to try via XP64.
The only thing which scares me is settings for SPD, i mean:
Even if i set personal configuration for memory modules, when i'll set the bios to manual (not limit) it will override the SPD data by choosing values itself...
How to fix it???
Plus after checking the SPD data inside my ram modules i found that ram dimms will run at 4-4-4-12 with the 266 divisor (6-6-6-25 for 400), so what kind of timings i'll have to set for the 266 divisor??? maybe 5-5-5-18??

[LIKMARK]

I can boot with 266memclk and "limit" setting for cl 4 4 4 12 1t timings, my system bluescreens one third of attempted boots though, wich implies inconsistent timings set. I am not sure if flashing SPD will help you.

[jan]

got my two 2350's today are the following results ok?

Cinebench R10




HWinfo32




WinRar, but only ~60% CPU utilization?

[LIKMARK]

Very nice jan! Wich board was that again? (lazy )
