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

[Rammsteiner]

I think I found the reason for my crashes... Another retarded reason...

Prime Blend would error quite fast, so I upped both Vcore and Vnb. It took a little longer to error than before. But it still errored.

Now Im at 1.35Vcore and 1.375Vnb and it ran 3h Prime belnd before I stopped it myself...

I dont know if I could lower the Vcore anyway, it was just looking for stability in a few quick ways to find out why it wasnt stable after all.

Looks like the NB needed more Volts then. Will do more testing soon though. RAM is back at DDR800 at the moment... Might as well try and use 3-3-3 timings now.

But to go short, Phenom is indeed a phenominal thing lol

I'm watching your results... your conclustion is the same conclusion I made. It appears that NB-VID is an issue. (Or it is at least something about the NB/HT.)

Any heat problems at 1.375 Vnb?

The problem is I can only go up to 1.275 Volts on the NB-VID with my current bios. (Gigabyte F5 for the DS5... the F4 BIOS defaulted to 1.3V but the machine was VERY unstable at that point.)

You also have to change that voltage in the BIOS since the AOD tool doesn't let you change it. (At least on this board.)

Depends when you call heat a problem.

With closed doors and me sleeping it hit 48~49 degrees. I guess, since 90nm Windsor had a max of 60, that 65nm Agena would be fine with that.

I ran 9 hours Prime Blend without messing up. Although I crashed yesterday after that 3hour Prime though. But this crash was different. Normally the screen freezes, sound goes on, then loops 2 times for a few seconds. Then I see very fast a few colours on screen and then it goes black.

But this time it simply froze, sound simply stopped and nothing else. The screen just stayed as it was. Whether that's a sign to more stability, or my GPU still not being 100%, I dont know. Running 1.375Vcore and 1.3875Vnb now (that's with the 49 degrees described earlier).

Also the whole NB is quite sensitive. I sued tighter timings, which my RAM can do but it crashed only sooner lol. Ill do another gaming cycle today and see how it goes. Then I might try some playing around with HTT's and multi's to get a sweeter spot for the RAM. After that trying to discover what Voltage might be lowered again.

Im wondering though, are the IMC's on Phenom 'the same' as on X2? In regards to Voltage scaling etc. IMC on X2 ran 1:1 with the CPU, dont know if this counts for Voltage though. But if it does, high Voltages wouldnt be much of a problem then?

IDK what to think about the vNB settings. With the CPU right at 3.0 GHz I've been as high as 2150 MHz @ 1.38v and as low as 1880 MHz @ 1.125v and all apparently stable. It's very confusing.

First couple of nights the room temps were stable but the last two nights have been colder and the machine is locked in the morning. I'm not so sure it likes room temperature as much as it likes stable temperatures. Well, water will help with that too, to some extent ...

[Rammsteiner]

wtf... I got another freeze a few hours back, ran Prime again but no errors. This was again the same freeze as earlier, just the screen stayed as it was without getting a black screen...

This sounds more like a GPU thing I think. Ill downclock it to see how that helps.

Otherwise Im going to scream at my Phenom.

And I just read someone who OC'd his PCI-e clocks to 125 which resulted in freezes while gaming... Ive it at 105, but might as well try to set it back at 100 and see. I would feel really stupid if that would solve it lol. Reason why I did that, cause the red mode for AOD OC's PCI-e clocks too, so I thought I would do it myself instead.

[EDIT] I just rebooted and noticed PCI-e wasnt OC'd. Completely forgot I didnt OC it anymore after last BIOS reset lol. Clocked my GPU back to 877 and GDDR4 to 1251Mhz. Lets see what that will do. I also lowered the Vcore (for CPU) to 1.35Vcore again. You might think it's stupid to change to parameters, but by lowering the GPU this much you rule out the GPU automatically. If a freeze occurs anyway, and it's a freeze where everything goes black again, it's definately a Voltage issue for the CPU. If it normally freezes it might be that the Vnb wants even more Voltage, if that doesnt help Im out of clues.

Man have I been busy...managed to do some playing



Got to love 3870x2's Thanks to Sapphire.




CPU at 3.2GHZ, NB at 2.6GHZ, Memory 4GB at 1066 with test 1066 spd some 3dmark Vantage action.

Hey... can you play Doom II on that puppy?



Maybe ZORK! (It would be so fast that it would get done before you typed in anything.)
