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

[Marvin_The_Martian]

I think he means that with the integrated imc and lower latency the memory is under more stress at the same mhz compared to intel, so it's more prone to being unstable at otherwise comparable settings.

well after a lot of work and frustration... i have concluded that my 9850 HATES 1066mhz ram =(. so ive been running at 800mhz mode... anyone else having the same problem with 1066 mode? i also have noticed that my computer is more stable at odd multipliers (11.5,12.5,13.5) than normal even multipliers... why? >.<

If you are using 1066 mode you have to do the following.

from a cmos clear or setup defaults.

Set 1066 mode...set voltage to say 2.0V and reboot
Enter bios and see if the minimum TRCD value is 5..if it is you are in 1066 mode.

If you have dimms programmed with 1066 into the jedec tables do the following on the dfi

boot...it will be at 1066 but the bios is confused
set manual for the ram speed and set 1066 mode

reboot

Now go back to bios , you should be in true 1066 mode.

on the DFI you may have more luck with 5-6-6-24-30-195ns(for 2GB dimms)

No you have it wrong you're 9850 hate 2x2gb Corsair Ram @ 1066

My 9850 Likes my 2x2gb OCZ Reaper HPC @1066 just Peachy!

I would send them sticks that you got Back to Eggy while you still have the chance and get the 2X2GB OCZ Reaper HPC from Zip Zoom Fly like I did and get the $25.00 mail in Rebate that comes with them cuz $100.00 for these sticks is like being able to rob someone without a gun legally.

You've got me visiting XS after a LONG time Tony, just awesome

ok, sorry if this sounds like a newb question. also correct me if i'm wrong here. as far as i know, amd cpus love low latency as opposed to higher bus. with that said, will it be better to run at speed below 1066 or 1000 and with lower latency. since the 9850 has unlocked multi, you can oc with multi easier than bus. true? i'm debating whether to get good low latency pc6400 or higher speed pc8500. i'm running a 5000+ BE at home and i can oc my ballistix to 944Mhz with low latencies of 4-4-4-12. i love the bandwidths and latency i'm seeing. which way to go pretty sums up my questions and my questions are;

high speed or low latency?
oc with multi or bus?
get pc6400 or pc8500?

thanks for all inputs.

Perkam!! Welcome back

[Oldguy932]

So has anyone other than me tried to do any real testing with better cooling than water? My 9850 only goes to 2.75 so I can't do much testing at all, all I know is that max htt gets reduced like normal and the nb gets some extra frequency. Maybe it just wants to be air cooled, but who knows. It almost seems like the cooler that keeps it closest to room temp without going below it would be the best config.

[Sparky]

Have you tried it on a different board, like the DFI or gigabyte? Some have said some boards are better than others

I have the DFI DK 790FX-M2RS and would love to put one of these B3s in it (especially since my 9600BE is so buggy I can't run stable @ stock at idle, gotta load it down all the time, most bizarre thing I've ever seen). Unfortunately I can't because I need a motor in my car so now I'm selling the board to help fund that, and gotta find out what to do with the chip, probably RMA it then sell the replacement I suppose. Stupid cars...

[Aussie FX]

some one want to trade me my funky 9600BE for a 9850 BE ?

You will just sell it.

It should buy a nice engine though

[Oldguy932]

Case closed, these chips hate the cold. The colder they get, the more vcore they need to be stable. Just changing the heater setting for the vapo from 100% to 0% required an extra 2 voltage notches, so instead of 1.1825v it wanted 1.2125v to run at 2.7ghz because it got like 5C colder. I might have to build an intel system to justify not selling my vapo now...

[Chri$ch]

got today my new hardware (Phenom 9850 BE & Asus M3N-HT Deluxe), its my first time with AMD & oc

dude you've got me worried! Where have you been!?
BTW
all hats down to Tony! I hate not having a time to run my 9850 samples


oh well I guess that after this thread only meaningful new thread would be with Phenoms 8x50

[Charles Wirth]

Update

Parts finally arrived, change in mobo.

[informal]

Chri$ch,great results!!!New Nv based boards seem to clock Phenom 9850 quite fine .
Keep us informed of your progress wrt OCing.

Fugger,nice pics,awaiting your results .

[BrokenWall]

Chrisch how did you get your hands on a ASUS 780a mobo. I'm trying to pickup a Crosshair 2 so i can go buy another 8800GT

single channel 1 512 sticK?

can you try DC and post back your results...

[Chri$ch]

yes, first time was singlechannel because the asus wont boot with my pc2-8500 sticks
and i tried it with one pc2-6400 stick.

at this time prime run with 2 x 512MB PC2-6400 sticks in dualchannel mode @ 250 x 10.

Behavior that you've experienced with memory isn't isolate case friend of mine, bencher it self, also had unbelievable headache with memory… mobo just refused to work in DC mode, or with high speed sticks (HyperX 1200 if I remember correctly)

Well im glad you liked the thread, its been hard keeping it pure AMD though but we managed it

Grab a new cpu man and join in

[possessed]

this is my first reply but I've been following the thread since it was on page 6.

I'm very pleased to see the new phenoms hitting 3GHz easily on air. I've bough a 5000+be as a temporary CPU waiting for the B3s to come out and looks like I made the right choice by not getting directly into phenom.

1. Tony, as you work for OCZ do you think my ocz ddr2 titanium pc6400 OCZ2T800C44GK will do 1066 with relaxed timers? (from 4-4-4-15 to 5-5-5-15)?

2. Chri$ch - how good is the nforce 780a chipset? Does it look as it performs faster than 790fx? I want to get rid of mine m3a-mvp deluxe. hated the damn board from the beginning (too many years using dfi's mobos)

--edit--
what? first post? and I registered almost a year ago. looks like I'm a newb in this forum

Hey man! My 9850 BE has the same batch as yours.

Not sure I want to mention this but... AMD chips were actually designed and optimized for lower voltages at the mainstream frequencies [for such uarch/fabrication] right since the early beginning. Hence it won't be odd to find they love voltage only in a low range and do not scale past it unless process tweaked. As Execs at AMD have explained, critical path delays were increased for this but need decreasing for higher clocks.

Also, AMD now has the 2.5GHz Barcelona 2360 SE retailing at 105W TDP: http://www.amd.com/us-en/Corporate/V...l?redir=CPPR01

So they now [finally] have 1.7G, 1.8G, 1.9G, 2.0G, 2.1G, 2.2G, 2.3G, 2.4G and 2.5G retailing in that segment - all of which were set to release by December '07 had there not been this TLB bug and a reason why they lost much profit over increased costs.


Any details on nV 780a?

[Brother Esau]

I get 2800mhz @1.23vcore stably So I am happier then a Pig in

[Marvin_The_Martian]

Brother Esau I think your doing boinc (right?) but I would love to the performance factor for the fah 504 console client and maybe a wu from the smp client.

[Nedjo]

I think is getting more and more obvious that B3 is really big progress compared to B2... just remember how painful was to bring up 9600BE past 2.5 with 1.4+V and look now... 2.8 is doable on default voltage!
