Settings for 400-450fsb

[negev]

Hi,

I'm having difficulty getting over 400fsb and would be grateful if people running between 400-450 would post their settings so I have a reference.. i know my mileage will vary but it would still be handy.

Thanks!

Still testing with this myself, and as raising the fsb increases memory i think this will be one of the biggest factors, so since i have different memory than you it may not be much help. I have 2x2gb of corsair 1600mhz. My cpu is a QX9650. CPU + NB are watercooled.

Here are my settings for 450fsb, these were just the initial ones i tried and seem to be stable, i'll be further tweaking and trying to lower my NB voltage soon:

CPU multi 8.5x (3.82ghz)

Ratio 1:4 cpu333

Memory clock 1800mhz

CPU Voltage multi 1x

CPU target voltage 1.46v

CPU actual voltage 1.44v

Vdroop compensation on

CPU PLL 1.508861v

VTT 1.35v

CPU GTLref +10, +5, +10, +10

NB voltage 1.67v

NB GTL default

DRAM voltage 1.98v

Dram pull up auto

DRAM pull down auto

DRAM Ref voltage default

Timings 9-9-9-25 1T, tRD (performance level) 7, tRTP 8 (10 actual).

If memory is unstable one solution could be to change the R2RD / W2RD same/different/same/different values to 6, 8, 3, 6.

doesn't that vdroop compensation scare you?

if the vcore droops to 0.9 under load, going from max load to idle with vdroop compensation on could blast a 2v spike through your cores..

this is a very simplified estimate, but as nobody has clarified this for me i only have assumption to go on. it may be that the blackops can somehow react instantly to current changes but as i said there is no documentation of this.

The VRD 11 specs for the PWMs for Intel processors feature Vdroop as a norm, for the sake of overclockers we put this compensation in, I use it all the time, CPU working fine.

I know a lot of people use it without seeing any damage, but have you actually tested the voltage regulation to ensure it doesn't spike when going from max load to idle? Logic suggests it would, and while this might not instantly fry your cpu it could certainly cause long term degradation.

yes, it doesnt spike during testing... if it does something has gone wrong.
