955 Max safe CPU-NB voltage? - Page 2

post #11 of 33
Quite honestly, I'm really perplexed how you got your CPU-NB that high. When I had my 955, anything higher than 2600mhz for the CPU-NB caused instant BSODs. Then again, I've been out of the AMD loop for a while so forgive me if my info is obsolete.

I would go for the 4GHZ/2.67 rather than at 2900.

I wouldn't expect 2900 to be stable, but if it is, then YES 2900mhz is better, increases RAM bus I believe...

EDIT: Increases RAM performance I should say. I'm 4ghz, 2800nb, ddr3 1600 8-8-8-24 1t. Great combo all the way around!

Right now I'm at 3.9GHz, 2900nb, DDR3 1782 6-9-5-15 1t, but it's unstable, and I don't think I can add anymore volts to the NB without damaging my CPU.

Raise it @ 1.50V. If unstable(might need higher volt.), not worth to run it at that speed.

So you're saying 1.5 for the NB is safe?

Yes it is safe. You can go up to 1.55v on the CPU/NB and it is safe.

I hit my old 955 with 1.55V(CPU/NB Volt.) and nothing happened, but I had a better cooler than the H70. Was trying 3000 for CPU/NB, but I gave up, couldn't stabilize

Oh, thank you. 4GHz is getting too hot/too many volts to stabilize, and 2.67GHz NB is bottlenecking my RAM. I'll go for 3.9GHz/2.9GHz now

Rep to all that helped.

You are not bottlenecking your ram. You need NB frquency under 2660 to bottleneck your ram at 1776.
