Hi guys.

Today, when booted Vista, instability returned, same config as last night, nothing was changed, I tough it was one of this no no days. Well if it don't want to go 3100, maybe it want 3200 , after some more volts, up where, down there, I manage boot 3200, check Everest, CPU-Z, etc, but when opening iexplorer, lookup again, never booted again, so loaded 3100 profile, .....

Same thing that happened to me. Worked yesterday, didn't today... Not a clue what it is. I raised the NB-CPU voltage and its been working well, but I have no confidence that it fixed the problem (or that it is fixed). I shut it off, let it cool down, rebooted, then it BSOD again....

This Phenom 9850 is a tricky unearthly being I tell you

[Brother Esau]

@aGeoM...Drop your HT Link Speed down and see how you fair at that point please

[Oese]

finally reached 3,595ghz @ 1,6v but not 3dmark-stable and only small improvement on super pi compared to 3,56ghz...

[Final8ty]

reached 3,595ghz as well with 1.5 but not stable.
I may try 1.55

[Brother Esau]

oh boy you're scaring me.. hottest ram on earth.. how much including shipping??


edit: temps:

Hottest Ram on Earth Where the heck do you get that from Oli?
These sticks are awesome and kick it on low voltage and are incredibly Fast!

I really hate parting with them I do but its only economical for me to upgrade for testing by selling existing hardware to offset cost of this insane habit I have.

IMO the FLEX Series have superior cooling and also what I know is that they have been the best 2GB Kit of Ram I have owned since DDR2 switch over out of 5 kits of Ram that I have owned even better then the $330.00 set of CELL SHOCK PC2-8000 that I owned too bad I cannot even begin to get close to what I paid for them back in oct which was $240.00 .

Contact me through PM Oli I don't want Vapor on my ass and no doubt he looks for opportunity to kick me in the nuts and give me brownie points

[Oese]

don't get me wrong.. i did not mean temperature...

Brother Esau,

Have you started to work through some of the BIOS settings for the Phenom yet? I looked through the early ones you posted, they seemed much more oriented toward the X2..... If there are some X4 ideas, I must have missed them (this thread is getting a bit LONG!!)

There are a zillion settings that may indeed affect stability for phenom OC'ing, but I have no idea what they do.

Here are some that I do not understand

From Advanced Chipset Features

Memory Hole
Memory Hole Remapping
Auto Optimize Bottom IO

From Genie (these are all somewhat mysterious for sure)

DCTs Mode - Ganged, Unganged ?
IH Flow Control Mode - Enabled Disabled
HT Link Tristate - Enabled Disabled
2x LCLK Mode - Enabled Disabled
UnitID Clumping - Enabled Disabled
CPI DID - 1,2,4,8,16
CPU FID - 09 or some other Hex number
CPU-NB FID - 1,2
CPU-NB FID - 06 or some other Hex number
AMD CPU Stepping - P0, P1

Any direction of help would be appreciated

Thanks

Dan

Greetings, my M2R got here yesterday, along with my 9850BE, my ram wont be here till Monday, in the mean time should I remove the chipset, and PWM heatsinks and check the grease, maybe put some AS5???

Not sure how much I can push it till I get a new PSU, gonna use my ANTEC 550watt TP2 till I get a new one....

It will also have TRUE on the CPU..

[aGeoM]

@aGeoM...Drop your HT Link Speed down and see how you fair at that point please

You mean 1.8 MHz?

Tony recommended a 7x ht multi above 3GHz.

[nanohead]

Tony recommended a 7x ht multi above 3GHz.

Why would you guys use a lower multi with an unlocked CPU?

[justapost]

Why would you guys use a lower multi with an unlocked CPU?

Getting an higher cpu multi work more stable with an lower ht multi is the point here.

[aGeoM]

OK, I'll give it a try, I'm burnig it ATM at CPU=3100;HTT=200;HT=2000;NB=2400;CPU-VID=DEFLT*109.15%;CPU-NBv=DFLT*103.7%

My POV is lower HT multi if higher HTT, but testing Tony's recommendation cost me nothing.
Maybe 331 it's better for B3's, and works that way...humm lot's of work to be done.

The answer on that one is no I have not done any extensive testing on Phenom as of yet and actually learning the ropes myself Also I do not know if you are aware of this but allot has transpired in my life since a couple of months ago. Moved back East cats been really sick been sick with the flue myself and blah ,blah ,blah and so on

I really have a hectic time since move just so much to do and also set backs along the way do not help much either. I only got the Phenom like a week ago anyways

In the HT Setting menu just worry about the top two and for now just leave the other 3 as is please!

Also what you want to do is quite simple Read this Guide on Phenom Architecture and Overclocking written by OCZ Tony......Click Me>>> Here!

THANKS GUYS!!! Terrific article by Tony. He's always very knowledgeable on the OCZ forums for sure.

Now I understand most of the things that I was scratching my head about....

I'm still having flakiness with the M2R and the 9850, but I have to play around a bit more. Running my memory @ 800 for the moment. Might buy the Reaper kit Campbell bought, but no one has them....

I also have a brand new Asus M3A32 MVP that I might unpack to test with. My first one spontaneously combusted (for real) and I had to RMA. Bought the DFI as a replacement, been very satisfied so far, nice BIOS for sure compared to the Asus.

Sorry about your cat dude, its a bummer, as we get quite attached to those little creatures. A couple of years ago, our great female cat (the one with the personality, as opposed to the male who was a dope), was sleeping under the open garage door, under the photo eye for the opener (she was small). We hit the garage door button, the garage door closed, and she got, well you know. Still a bummer.... a wonderful animal. We all miss her.

BTW, I'd be more than happy to beta test firmware. Been an engineer in the biz for 2 decades, and am used to pulling my hair out (although I have none left )

To be honest the TIM that D.F.I is using is Shinetsu and you really cannot get better temps then what on there I have tried with Arctic Silver Ceramique and I actually just not long ago removed the Heatpipe assembly and reapplied the Shinetsu that comes with the Transpiper Kit and the temps actually improved

I would say carefully take it apart and Inspect it and see if the Shinetsu is applied properly as sometimes some say they there was not the right amount applied but thats really the odd ball case!

If it needs a little more just add some shinetsu if it does not just re-assemble

OK...Cool please send me a PM saying you wish to do so as I keep records of who tests Beta Bios so I have it logged so I know who is testing and is eligible for Free re-programming

The compound they use is actually not a patch on the OCZ freeze, i have never seen anything work so well and have next to no exposure on the net.

I know I cannot believe its not a staple amongst Overclockers in general I will be ordering a tube for myself and thanks for reminding me Tony I keep forgetting to do it.

[MagnumMan]

Two issues.

1. I decided to try the M2R on my bench with the following config:

(1) ATI HD 2600 card in PCIe Slot 1
(2) 1gb memory modules in DIMM1+2
(1) Phenom 9600
(1) USB Floppy
using a Thermaltake Toughpower 850W
Provided 24-pin, 8-pin power to mobo; 4-pin CPU fan; provided 4-pin floppy style power to the first PCIe slot.
Other than that nothing is plugged in.
The BIOS is 12/11/2007 I believe (from what I saw at startup after clearing CMOS)

I have cleared the CMOS.
It gets to "AMD Data Update... Updating DMI Data... Success"
and then nothing at all happens. I waited 30 minutes each time and tried 3 times.
Something is wrong but I have no clue what it could be.
I also tried optimized BIOS settings, no good.
I also tried manually setting a bunch of things not in use like the 3132, SB600 IDE, etc. No good.
I can't even boot from floppy to flash the BIOS.

Any clues as to what is going on?

Issue #2:

I want to use this board with 3x HD 3870 hardmodded to 1.7V and running around 1000MHz GPU each (some over, some under).

I also want to use a Promise PCIe x1 FTTX4650 card in the PCIE x4 slot with the 3 video cards. According to the manual this is not possible, which would seriously piss me off, why put it there if you cannot use it.... has anybody used 3 video cards (16x/8x/8x I believe) with something in the x4 slot too?

Sapphire Bios Guide says:

HT Link Width: 16bit/8bit mode, CPU to NB bus hyper transfer bandwidth
HT Link Frequency: 200~2600MHz (2.6GHz), CPU to NB bus hyper transfer speed
IH Flow-Control Mode: Enable to support the use of the Isochronous Flow-Control Mode
function to provide reduced latency for certain classes of southbridge traffic
HT Link Tristate: Enable to tristate parts of the link in order to reduce power consumption.
By default, no lanes are tristated. The CAD and CTL lanes may be tristated together or CAD,
CTL, and CLK may be tristated.
2X LCLK Mode: nil (will be removed by next version)
UnitID Clumping: Enable to support UnitID clumping to increase the number of outstanding
requests supported by a single device. It maybe enabled for PCI-Express GFX links in certain
configurations. Clumping may be enabled when using only the lower number bridge within
each PCI-Express GFX core

Tony,

By the way, the B3 Article at TTR was quite good. Took a couple of reads, but it was very informative. Actually cleared up quite a few confusing bits from the DFI BIOS and AOD. AOD actually has some benefit now that I have a Phenom parked on the board. I found little use for it with the BE 5000.

I just ordered some DDR 1066 2X2GB Reaper kit from MWave.

Looks like I've got enough ideas to work on the best clock I can get out of the BE 9850. Hopefully we can get the 790FX-M2R and the 9850 to behave consistently at higher clocks. Then I can install the Reaper kit and see if I can get the whole shebang working at peak performance.

Nice info

remember AOD shows yellow default for B3's and is fast, Red is even faster though.

regards the reapers im beta testing a new spd, im thinking of letting you and Campbell have a play with it to see what you think.

9750 and 8650X3 arrived today, more testing soon
