Overclocking 7750 Kuma BE

post #1 of 11

Thread Starter 
Hey folks. I just started playing around with this setup again:
7750 Kuma BE CPU + Asus M3N72-D. All stock coolers.

The multiplier in the BIOS seems to have no effect. I can only gain performance via changing the FSB.
Windows reports the speed change, but CPU-Z and HWMonitor both report the stock 13.5 multiplier.

I believe I read somewhere that Nvidia chipsets can't modify the core multiplier of AMD chips. Is this true?

Also, my BIOS monitor shows the correct assignment of temps for the cpu and motherboard, however every reporting software I have tried seems to switch the two. What's up with that?

Lastly, if a board is reporting acceptable temps; is it still likely to burn out other components that are non-reported? For example with GPU's, if you push them to hard without cooling the voltage chips, you can fry those.

Thanks for the read,
Flappy

I have several MSI NF980 GD 65 motherboards with the nvidia chipsets , they have no problems changing the multiplier of the black edition chips I have used them with. Not familiar with your board at all, so I cannot say if it's capable or not.

Thanks for the reply. One other thing of note is that the multiplier slider is hidden in ntune. That's the only OC software I have found that detects the chipset.

How far have you got your Kuma? I only got mine to 3.1ghz before it crapped out on me. Its currently the heart of my Dads Htpc, but I am going to upgrade him soon.

I cannot bet ntune to work properly with my 980's , not sure why. The 7850 BE's that I had were on MSI DKA 790GX motherboards, both of them petered out at about 3.5 ghz. Those boards were very easy to overclock on ( could use onboard dip switches to up the fsb), and because of the 790 chipset, AOD could be used with them , nothing simpler than that. Reference clock on that board would hit 280 or so before getting difficult, I have a validation or 2 on a hard drive somewhere in the stack of parts that used to be my basement tongue.gif

My motherboard is a lower end one. So my clocks have not been that high. I was running mine at around 3.25, but having some boot issues. I know I could get it higher, but am reticent to on stock cooling, as I already hit 50 degrees under load. I sure would like to know why the multiplier isn't working though.

Hey! I figured out the multiplier thing with some help from this post:

http://www.overclock.net/t/1206300/changed-the-cpu-nb-in-bios-but-still-shows-2000mhz-in-cpu-z

"I've had a couple of finicky Asus boards that wont change multipliers without a power cycle. Some boards do it automatically, some don't. If it doesn't power cycle on it's own, try doing yourself after the bios settings are changed. This is not a general rule but it could work."

Thanks metal_gunjee!

If I recall, that was my highest stable overclock of that particular chip. Not sure if any of the settings there will help you or not. Good luck thumb.gif

You can t go to high with Kuma .Phenom 1 were extremely poor performance wise and with low overclockability.
It s a weak contender and you may get instability and nothing more.
I wouldn t force that chip.

I can't seem to get past 3300mhz with just multiplier, FSB, or combination adjustments. Even with voltage set to 1.5 it crashes.
