i7 950 Bclk Wall

post #1 of 8
Thread Starter 
I've been ocing my 950 for a couple of weeks now and I've hit the bclk wall of 198 (198*21). I run on air and any further bclk improvement, and I have to raise the voltage dramatically. I'm getting a water cooling system very soon and I was wondering if it's worth giving the voltage the full beans for minor performance gains.

If so, then what's the best way to improve performance? Higher bclk or multiplier?

What voltages are you using now?

What are your load (LinX or Prime95) temperatures?

Why not use the 23x multi?

You'll have more BCLK headroom that way. My Sabertooth likes 175 x 23.

vcore: 1.33750
qpiv: 1.28125

Temps shoot up to just over 90, but the room was quite hot during testing. About 26 degrees.

At about 21 room temp, it goes just over 80.

Doesn't running lower bclk reduce your ram speed as well?

My RAM is now @ 1400MHz. But honestly my system feels no less snappier minus 200 MHz.

I mean give it a shot. It may work out better for you.

Voltage seems about right.

Temperatures are a bit high.

Maybe your chip is not a good overclocker?

I have reached better gpu benchmarks with a high bclk <200> then highier cpu clock.
Lowered my cpu 200mhz and raised bclk to 200. and increased overall video performance on my sli rig.

Would be worth testing out, lower your clock and your temps while increasing your bclk and run 3dmark xtreme, twice before twice after.
