Thanks for that, I got AOD working now, like you say it only allows you to change the CPU Multis, but the stability tool works as well, which is handy.
I havn't gotten around to testing anything yet, goling to give it a go tomorrow.
I think the way I'm going to do it is to drop the multi down to x10 in the BIOS, and the FSB to 220, so that its still at the stock 2200MHz, then boot to Windows and try to raise the core multi's one by one to x11 to see which core with mine is the problem....
It certainly makes sense, that this is the problem, i.e. AMD were under pressure to get Phenom out, but as everyone knows they were having trouble getting higher speed bins...
It also explains the tri-core that they announced, seems that they must've been having a large number of CPU's with a core that wouldn't run as high, so instead of scrapping the lot, they just disable the one core and then bin it at a higher speed tri-core, rather than a low end quad-core..... rather than lose $$$$.
It really does explain the whole tri-core that AMD announced out of the blue...
Anyway I'm going to have a go at it tomorrow to see if I can get anywhere with my Phenom.....
I think I'll put my RAM divider down to 667 as well, just to make sure theres enough headroom on the RAM.
OK so I couldn't sleep so I thought I'd have a go at it tonight....!!
I set RAM at 667, FSB at 220, CPU Multi x10, HT Multi x5, increased the CPU>NB Voltage to 1.4v, NB Core voltage to 1.4v and SB Core to 1.6v.
POST'ed OK, Booted OK, opened AOD,
changed core 0 multi to 10.5 and tested for 5mins with AOD stability test, all tests, > all OK > set back to x10
changed core 1 multi to x10.5 tested as above > all OK > set back to x10
core 2 > set to x10.5, tested as above, 2 mins in, BSOD, secondary processor blah..blah... > re-booted, started AOD again
Core 3 > set to x10.5, tested as above, all OK.
So again it looks like its the 3rd core thats the problem with me as well....
So anyway, having isolated that I tested a bit more sticking to Cores 0, 1 and 3, leaving Core 2 at 220 x10
Raised all other Cores to 220 x 11 = 2420MHz
Tested for 5mins as above, all tests, all OK, no problem....
So I thought I'd give 3DM06 a go....!!!
As soon as I opened 3DM06, instantly froze up on me, black screen, but the display hadn't failed as pressing CTRL ALT DEL, brought up task manager, but at that point it locked up copletely needing a reset....
At that point I decided to call it a night.......
Typical just before I tried 3dm06 I was working out already, what multi to put the bad core on, if I had a fsb of 250 for the others, to give 2750Mhz on the good cores....
I'm going to have another go tomorrow, I'm thinking it may be down to the HT possibly, not sure, but I think I'll try lowering the HT multi to x4 to see if that helps at all.....
Oh yeah I increased the CPU voltage from 1.2v to 1.25v as well....!!!
But it does seem as though the problem lies with 1 of the 4 cores.......
So the whole reasoning behind AMD's tri-core is becoming all too apparent now.....!!!!
Its not some eco-friendly plan of AMD's to provide multi core at low power, its just a way for them to sell all the quad-core rejects.......
So buying a tri-core is like buying a broken quad core CPU, not sure its something I'd want to do....!!!
Although that said, it seems that to get an OC out of the current Phenoms, on an AM2 mobo at least, you can only have a tri-core OC anyway.
Just speculating here but maybe this is the whole reason behing AOD being released, to make it possible to OC individual cores, as AMD knew that in all likelihood the majority of CPU's would have at least one core that would clock significantly lower than the others.... so the only way to OC is via independent Core clocking, something which hasn't been possible before AOD.
So anyway tomorrow I'm going to try the 250 x 9 in the BIOS for 2250MHz
Then increase the multis using AOD, on Cores 0, 1 & 3, to x11, giving 2750Mhz.
I'm going to put the HT multi at x4, so still giving a 1000MHz HT speed. (250x4)
But I'm wondering then about the NB speed, which with a x9 multi is going to be 2250Mhz, thats quite a lot higher than the stock 1800MHz.
And theres no way to change the NB multi in the BIOS unfortunately, it would be really handy to have an option there to reduce the NB multi to keep the NB speed down a bit........
Now I wish I had a 9600BE with its unlocked multis.... might be able to have some fun with that.... !!!!
