i changed my cpu gtl refs to 0.660 for both the 1/3 and 2/4 values - nb gtl is on auto - im not sure what to do with that. i found with these cpu gtl refs i got more Gflops after running Linx:)

my nb is at 1.24 - and seems to be stable - i didnt want to raise it that much as its cooled with stock p5q deluxe heatsink and a fan at the side.

u recon then for an fsb of 460mhz - raise cpu from 1.275(BIOS) to about 1.285v? and nb to 1.26 - 1.28? the cpu pll is at 1.54 - i know that a high pll will kill a cpu so its ok at 1.54v - how high will it be ok to go? cpu is liquid cooled BTW.

For those speeds mine worked best at 0.635 for both cpu gtls, as I went higher (480s) the higher gtls worked better up to 0.655 for both. Auto on the NB gtl worked fine for me up to about ~470fsb than I set it to 0.665. 1.24NB is not alot especially with a fan on the heatsink and 1.54 pll is also fine. What vid is this chip?

i think my VID is 1.1725v.

i thought the cpu gtl was 2/3 of the vFSB/VTT?? so 2/3 of 1.26 is 0.840 = 0.660*1.26 = 0.8316.

is this completely wrong???? or do you just have to mess around with the gtl refs???

or do you set lower gtl refs for lower fsb (start on 0.635) then go higher to like 0.670 with a higher fsb?

help on this please!!

Ok here's mine at 7+ hours stable, doesn't seem to like voltage, any advice on where to go from here would be appreciated.

Edit: just re did 1280k with PLL 1.55v and pass, take it from there.

0.635 is usually a good starting point with these chips at low to moderate fsb and may need a little more as fsb goes up. Every setup is a little different so you need to find out what yours likes best. Try this 456fsb with 1.2625vc, 1.54pll, 1.26vtt, 1.28nb, both cpu gtls at 0.635 and nb gtl on auto. Also do you know for sure if your ram will run stably up to 1100+? Have you tried dropping down to 1:1?

i'll try my ram at 1:1 - but i wanted that OC'd too. I've read a couple of reviews - this ram need volts to OC even 20Mhz over stock - i was aiming for 1100Mhz @ 2.2v (stock 1066@2.1v)

I'll try 1:1 and those BIOS setting this weekend when I get time!!

Was able to squeeze a little more out of it last night.

Very nice Hoss :clap: To stabilize the Quad's above 4600Mhz takes a LOT of patience and skills. Welcome to Q9650@4650+Mhz stable club.

Thanks and good luck with your ln2 benching. :up:

Hoss331 - i tried my ram on the divider below - so they ran at 931mhz or something with fsb at 458 - cpu@ 4.124ghz - this was fine - only thing was - my linx Gflops output was far less because my ram was like nearly 130mhz slower per stick.!! so i recon i'll loosen some timings to get them running at 1100mhz.

Good to see the Q9650 thread still going strong! Makes me miss my old chip.... sure did run a whole hell of a lot cooler than this 860.....>.<

andressergio,which batch did you get?
did you get an even lower vid chip?

HWbot.org Q9650 HOF

Just got back the 1st. place on SuperPi again. Man that was hard to beat because after the Country Cup Competition crazy Ociers all over the world submitted their Q9650_Spi1m run's, the WR was lowered by 0.200ms.

So here's my latest run:

http://i46.tinypic.com/4slaoo.jpg

Also lowered my wPrime32m:

http://i45.tinypic.com/2960h1v.jpg

Need only 500points on PCMark05 to get this thing wrapped :up:
