I should know this.. but I don't, never did it. How do you disable a core?

You can do it in BIOS if it support's it. You must have ACC function, and additional option to disable one core.

If not, you can disable it in Windows. Just go:
- start
- run
- msconfig
- boot tab > advanced options
- set number of processors (cores)

I do have the ACC function, but nothing to disable the cores in it. I could unlock a core but I have no cores left to unlock. The Windows method will work just fine, thank you very much!

Need some help here from you guys running full AM3 setups and especially from anyone with a GD-70. My Ripsaws showed up today so I finally put in the GD-70, thing seems very nice, got the newest 1.7b3 bios and was finally able to hit 7-7-7-18 1T on the RAM. But I'm having issues with the CPU OC now. Getting a lot of google chrome acting up and it's getting annoying, I have even gone as far as dropping under my perfectly stable 24/7 OC that I had before and I am still getting some issues.

There are a ton of voltage adjustments in this bios like CPU VDDC and such. Maybe I'm not setting something correctly on those, any help here would be fantastic, just puzzling. Plus note is, I made it into windows at 4130mhz, but then it just kind of froze, could move my mouse, but wouldn't go anywhere. So thats higher than I ever made it in on my DFI board, good sign, just need to figure out how to use this beast.

Yeah basically the same settings I have, tweaked a few of them, this is getting frustrating, I just got sick of it and jammed 1.55v down its throat, which is what I am posting on now. I was running 3,802mhz on 1.425v and it was running fine on my M2RSH. But even I think this is going to fail, very disappointing. Hopefully I can figure it out.

 

[Assassin48]

go back to your old bios and see if you can get it stable

on my ch3 i have to use the old bios for my sempron and athlon when i want to overclock because this new one wont let me pass 3.4 with out freezing or bsod

but the new one works better for my 720 to overclock

 

[1Kurgan1]

Seems to have stabilized, gonna mess around a bit more, getting ready to put vista 32 on a spare hdd for a benching hdd. Flashing is extremely easy on this board, so I just might have to check out other bios versions.

 

[1Kurgan1]

Moved back 3 bioses to 1.6b3 and stability seems to be found, granted I am at 1.44v right now, but I havent tried 1.42v. Crossing my fingers here.

 

[Assassin48]

whats your OC right now ?

 

[1Kurgan1]

here's my current settings

Just snuck into 7th on 1024, still seems funny though, everyone once in a while the screen will flash black for like half a second. Otherwise it's running good. I have the RAM, NB, and HT speed way down as I was testing to see if those were the issue.

I decided to go with Win 7 7600 32bit on the benching drive, dont have time to install that tomorrow, maybe Friday or Sat and hopefully have the bugs worked out by then and can get a real nice OC and get some more placing on the 240, then gotta find time to punish the 720 and see if I can unlock it on the GD-70.

 

[Assassin48]

So far its looking good

 

[1Kurgan1]

Yeah, will just take some work, I'm sure I'll figure it out, was just hoping to get some nice mhz out of the RAM, but think I'm just going to have to go for low clock speed and tight timings, same results I guess. Already ran it at 310fsb, so nice to know that 300fsb bottleneck is gone.

But got to figure out that black screening issue and some programs and randomly freezing, strange thing is, no stressful programs. Mostly just google chrome. I think it might have got messed up from when the OC'd were really funky, might have to just reinstall it.

 

[Assassin48]

which ram are you using the 4gb gskill ?

For some reason, I am not able to comprehend this:

CPU Vdd Voltage: This is the positive voltage supplied to the FETs. MSI states (on another 790FX board with Phenom II) that 1.3 to 1.4V is typical safe value, however we've increased it here because we've added additional cooling to the CPU socket area with two large fans.

CPU-NB Vdd Voltage: This can also help with increasing the integrated memory controller overclock - we've not increased it here, but considering AMD claims 1.4 to 1.5V for the CPU-NB core for optimum results, the CPU-NB Vdd should also be ~1.3 to 1.4V.

CPU Voltage: Typically the 45nm SOI Phenom IIs can withstand quite high voltages so 1.5V should be OK if it's properly cooled. However it's worth mentioning that this is wrongly labeled, and is actually the voltage offset, as increasing the Vdd above adjusts this value as well.

CPU-NB Voltage: Like the above setting, working in combination with the CPU-NB Vdd setting will give you an additional voltage. Work with mostly Vdd and start with a small setting here.

Now the screen shot accompanying this shows for eg CPU VDD at 1.45 and CPU V at 1.51. Now can someone explain to me how this adds up. previously I thought it was a straight addition, so I left it alone and only used CPU VDD. Now it seems like I am wrong here and its an offset....so how does the offset work????


EDIT: So after a bit of googling it seems that offset kicks in after boot or something compared to the normal VDD which kicks in at boot time. Is this right?

Trying to overclock my 965 on the GD70...Yea im so lost i guess ill try more tommorow

 

[Assassin48]

I always use CPU v for my voltages . the VDD on my board starts at 2.5 i believe so im lost

CPU VDD is the voltage regulator of the CPU-V
CPU V is the voltage of the CPU itslef
CPU-NB VDD same idea as the CPU VDD, but for the CPU-NB
CPU-NBv is the voltage for the CPU-NB
CPU PLL voltage is something i've never heard of.

So here is the run down: Voltage comes in from the PSU, and then goes to mosfets, and then to the CPU and CPU-NB. The Mosfets can be regulated to send X amount of voltage to the CPU and CPU-NB, this can be further controlled by the VDD, which is bascially your head room.

 

[1Kurgan1]

I have using the 4GB G.Skill Ripjaw 2000mhz kit. About the CPU VDDC, it seems strange. I set my CPU V to 1.425v and then I start raising the CPU VDDC. By the time I get to 1.375v on the VDDC it has actually dropped my CPU V to 1.175v. For each notch the VDDC goes up, it drops the V a few notches.

Too many settings here Came back this morning to my comp on the login screen, so it has crashed. And crashed with low RAM speed, NB speed, and HT speed. So its narrowed to something to do with the CPU.

Anyone know of a good overclocking guide that explains the overclocking settings in the bios. I can copy a picture but i still have no clue what im doing. Also need one on how to oververclock DDR3 ram also, Im a bit rusty. I read through this thread on some other sites but its not sticking. i get the that with thse chips you play with the multi and try to leave the FSB alone but after that i dont know whats good voltage settings and what not.

Will be here again soon with a 955be : ]

Thats a harsh board to start out with to learn how to OC, I am decently knowledgeable about OCing and even I am making my way through this and figuring out each piece myself. I highly suggest you attack each area one at a time, exactly like I am doing. I have found where my RAM is stable, I am currently working on my NB, then I will try HT Link, and final will be the Proc. RAM I would just stick to the DRAM Voltage, NB has it's own voltage and it's link voltage, start with the NB V, then mess with link and see if that adds stability. HT I'm not sure if that voltage should be touched.

Very nice

Yea i was abit overwhelmed by all the options, Im used to cranking up the FSB and and the cpu volts and that about it. I will defiantly take you advice when i get home and try to tackle each section a lilbit at a time. Thanks for the heads up

 

[1Kurgan1]

This board is really begging to irritate me, I can't even manage to get the NB stable at 2500mhz, don't know how much longer I can take this :/

After he snagged Cold Storm's 955BE before I could even see it, I went out and bought a 955BE new. This'll be my first AMD build so I'm definitely going to be asking questions about overclocking it.

 

[dir_d]

I need to know what are safe temps for a 965BE anyone know?
