Could B3 Phenom be the rebirth of AMD....+1000MHZ OC done!

[Seraphiel]

You might have missed the graph for FSX. It was reaching 100% a lot of times on a quad.

I missed it. Didn't know FSX could reach 100% on a quad. Nice to see >2 cores used with significant load to each.

3DMark06 ran at this resolution (1024x768 [monitor's max]) doesn't seem to benefit a lot from extra CPU.



Synchroclocked at 2.8GHz:





Multiclocked at 3100x3000x2900x2800:

hmm probably not worth it then mate.. thanks for doing it though. Wonder why your cpu score is lower than mine i get around 4000.. @2.8 and when i do it at about 3.1 i get 4200

[KTE]

Im wondering, did anyone hit high RAM speeds yet with DDR1066 mode? Cause somehow my system does seem to like HTT more now. Im testing CPU stability right now, but if I would go from DDR800 to DDR1066 mode it should run on DDR1200. But Im wondering if anyone actually hit such speeds at all?

Yeah many times, easily.
But 626 is tops stable, which is 150MHz too low for the RAM.

How is AMD overdrive working out for you? I hear it's still crap but I'd like another opinion

It's fine for long now, board BIOSes are what make it react crap.

Which OS is that in?
Something majorly wrong there bud, your scores are very low for even 2.6GHz.

3563 CPU is what I get with a 9500 at 2.42GHz: http://img73.imageshack.us/img73/453/2k62420bo4.png



Very far from higher MHz perf. 2.68G hits 4k.

2990MHz hits around 4400: http://img233.imageshack.us/img233/8956/2k62990sb3.png

That's what I wanted to know, thanks

The difference is probably due to the resolution I did the test at. I stated it so there'd be no mistake about directly comparing my scores to "normal" ones. The monitor on that machine maxes at 1024x768 while 3DM defaults to 1280x1024. Because of that, I had to run at a lower, non-standard resolution.

Also keep in mind that 3DMark doesn't serve very well as a CPU benchmark. Other workloads will benefit more or less from the multiclocked config--your mileage will vary. Besides, if the extra speed is free and you can see it manifest, why not take advantage of it?

[KTE]

We know its not exactly a good CPU bench but for the intended purpose here, 2k6 can show the CPU speed very well actually as it scales with it. Thats how we can compare it to one another
I'll check out the lower res results and see what it gives, if it has any quirks.

Oh, I forgot to answer the question of what OS I use: Windows Server 2008 x64 Enterprise

Is it... good?.

Ive XP64. Im happy with it, but wondering if server OS's are any nice, and this one is pretty new with DX10 right?

Indeed so. I enjoy Server 08 more than Vista or XP. It's like (and based on) Vista except not broken to the point of uselessness. It supports everything Vista does including DX10.

dude you use Vista, Server 2008 and Vista uses the same codebase, heck Vista SP1 kernal = Windows Server 2008 RTM kernal

Windows Server 2008 with workstation pack = vista basicly, so Windows Server 2008 is stripped vista

anyway, Vista and Server 2008 will have lower 3dmark score vs xp and xp x64

Didn't I just say that? Server 2008 is so much better than Vista. Whatever they took out (DRM bull?) made the system a lot better for normal tasks.

server os sounds good... would it be worth me switching from my os?? ive got vista home premium...

you can use the workstation pack to transform it to vista
did someone get a nice 3dmark vantage score?
my default is http://service.futuremark.com/home.a...&resultType=19
looks like the new 3dmark likes phenom alot

[Particle]

You don't need to install any sort of workstation pack. Just re-enable the theme and sound services and you've got a working desktop system.

[KTE]

Vantage likes MCP78 more than 780G though

[dng]

Particle:

i see you're running windows server 2008 and you seem to like it a lot. i've been running the 64bit version for weeks now and i can't imagine going back to vista. of course, i turned it into a vista look alike workstation. i even did some hacks such as enable superfetch and such. do you know how to get readyboost to work? so far, i like ws 2008 a lot. i like it so much, i even put the 32bit version on my acer laptop which is a celerom M170 or something. it runs well on my laptop too.

[Particle]

Good catch, dng. I need to re-enable superfetch myself. But yes, I really do enjoy it. I used Vista Business x64 for a long time and found myself going back to Server 2003 x64. I ran that for a long while, but '03 kept eating the filesystem on my RAID-5. The second time that happened, the RC for Server 08 was available so I tried it. All I can say is that I've been hooked ever since then and can't imagine going back to XP64, Vista, or Server 2003. I've tried them all.

[bingo13]

AMD has hotfix drivers on the press site that flip the scores back to normal. NVIDIA did a lot of fine tuning on the 175.12 drivers for this program, actual games still trail the 780G by a fair amount.

[KTE]

^ As it should be, thanks for the update
Odd how one driver can totally twist things the opposite way around.

[Rammsteiner]

Wow, Phenom is pretty sensitive for subtimings!

I thought I could set a few subtimings right away since I had these with the X2. But I went gaming and got every hour a freeze, got pissed about it and thought it was a dieing NB. So lowered NB multi, ran Prime Blend. Error straight away. Added Vnb and Vcore, error.

Added a lillte bit of Vdimm, still error. Removed the subtimings from Memset and it's still going... Wicked lol.

These timings are crap though in the way off resulting in instability. Set too strong tCL, tRAS etc is very obvious. Freeze with memset and no boot via BIOS. Same for things as MAL/MRL. But some timings just go do like a lot of things and then suddenly so their ugly face and crash your system...

Now I 'just' got to find out what timings caused it.

[Rammsteiner]

Or do more investigation, now it crashed after 1h and 10 minutes. Maybe NB or DDR1066 related...

[QuietIce]

Thanks for the article Tony! It did straighten out a couple of sticking points for me. I'll certainly try lowering the HT Link to increase the OC.

A quick question for anyone - what is the Mem VDDQ in AOD? It doesn't match the BIOS setting for vDIMM but doesn't seem to be effecting the (DDR2-800) RAM OC in any way.

Thought I'd chime in here with my Phenom results so far - 3010 (215x14) ~ 1.34v; NB running 10X @ 1.34v. CPU-Z Validation
Not yet confirmed stable though 3008 (188x16) is confirmed by two days of steady crunching with ~22 CPU hours of validated work on the books ...

[Rammsteiner]

What's your Vcore at?

Also, best way to test, I just noticed, is really using it as your 24/7 system.

Ive done a lot of testing and in the end, I started to play some game today and it froze... Tried changing subtimings, even removing them... Changed from DDR1066 to DDR800. But in the end, now Im running HTT200 for a while, CPU multi 13.5 and NB multi at 11 and it's still playing now. Although Ill play a lot longer before I consider it stable, but Phenom stability is actually very hard to test lol.

As KTE and justapost did, you got to search for instability really. I hope this is stable so I can go back to previous settings and just set a lower NB multi and be done with it.

[EDIT] Just as I made this post and went back to the game (windowed), it froze again... NB now at stock, if it happens again Ill try and see if it might be my HD3870... That one is running quite high but I did a 2h+ FUR stability test yesterday... but you never know.

[dng]

what started out as a sign of hope, has turned into desperation. it looks to me people are really having a hard time ocing this B3 phenom. hopefully the new chipset coming in june will bring more hopes. maybe this 790fx chipset can't handle the higher tdp 9850. i read that ocing the 9850 can kill your board due to the higher wattage that the board can't handle. anyone measure the tdp when ocing the 9850? maybe amd will finally get it right with the 45nm deneb. maybe there's still problem with the TLB, just my thought. i'm definitely holding out and keep my eyes on this B3 revision.

I agree that you really have to search for instability. I had the following settings clocks:

Core0: 3100
Core1: 3000
Core2: 2900
Core3: 3000

I used it in daily activities (checking mail, surfing the web, playing CS and Supreme Commander) then I ran an 8 hour OCCT test and it came back stable. Then after about 30 hours of normal use I went to rip a CD and BAM!!!! it crashed. Well, crap...thought it was stable.
