Next step is 471x8.5 stable (to break the 4Ghz barrier for a cheap quad CPU!) with the g.skills limited to 1570 as there is no way they will work above 1800 Mhz (will need better memory for that - wish I had the corsairs ).

my quickest 32M time so far, though memory clock is too low really for best efficiency.

weather here is perfect (with heating off) to push for 5ghz this weekend. Sub-zero ambients in the cheap labs.....

also trying out higher max mem size at the moment (680)

vNB 1.52V / vDIMM 1.93V / vCORE not tested for min




EDIT: updates




initial value is high for this run but still ok.




i had to re-do my OS a week or so ago and this is as close as i can get to 11.00m / 4Ghz -
about a second slower than before. Mem timings as tight as possible for this kit.

what bios do you have with this settings?

[emvella]

what bios do you have with this settings?

bios 1003

doing final testing with prime95 for 471x8.5

[Gullo92]

bios 1003

when do you finished the test of prime95 can you post your new settings with 471x8.5 please ?excuse me for my english i'm italian.

[fox3]

I was having problems running stable with 1003 or 801. I went back to 501 and have not had a problem with IBT or Prime.

can you post your setting into bios of q9650 please?

[Smooth]

can you post your setting into bios of q9650 please?

*lol*
I ask myself , is that the only english sentence you know ???

Cause :
You keep on asking allthough everybody is trying to explain you why this is sooooooo senseless !!!

[fox3]

can you post your setting into bios of q9650 please?

I am using settings posted in this thread for the Q9650 with some minor tweaks. If you go back a bit you will find them.

What CPU do you have? Post your BIOS settings and maybe we can see if there is room for improvement.

[cheapseats]

the best two of three 32M runs i did at this clock: passed all three, so possible i could have stayed
with same mem timings as 580FSB run

sub 9 minutes seems almost in reach now, but balancing this kit's clocks + timings with stability
starts to get difficult around 950mhz (595FSB / 5:8)

With luck the weather will stay cold enough this week - max CPU and NB temps were <30c with 32M load

590 x 8.5 / 5014mhz




vNB 1.55V (set) / vDIMM 1.97V (set) / vCORE 1.53V (set) LLC on

(maxmem 680 / LSC / SpiTweaker CW )




used CDT for this one and went back to tRAS 12. Run speeds up at Loop 4, compared to above.

(maxmem 680 / LSC / SpiTweaker CDT )

i don't know specific 1M tweaks - just ran this after my 32M.
Will try a higher clock for sub 9 seconds next time, but 32M is the priority.

bios 1003

doing final testing with prime95 for 471x8.5

Seems impossible to get it fully stable with the above combination of hardware and settings. Was almost there but with memory timings severely degraded which defeated the point of having cpu at 4ghz. Seems like 3.84 is the limit for stability for this cpu combined with good ram performance.

Will try higher fsb's with lower clock ratios......and scores more bsod's

[cheapseats]

back down to 7.5x multi to test again for lowest mem timings using 590-595FSB. I managed this run at 950mhz with almost same timings as the 571FSB run (tRFC 52 to 56) Trying to minimize the clocks needed for sub 9 minutes with 8.5x multi

i could only pass 32M by dropping max mem size to 580MB (from 680). Could be some cost to that but not tested yet.


vNB 1.57V / vDIMM 1.98V / C/Waza not used

Have you managed to get the GSkill Pi over 1800Mhz stable?

I can't seem to get mine stable over 1800Mhz...The furthest I have reached is 1869Mhz PL6 2T CL8 Prime 1 hour blend stable but IBT only passes 3 runs at max stress...oh and both Dynamic Read and Writes are both enabled

No, am away from home for a few days. Only managed 1800 so far. If u got 1 hr prime blend then try prime small fft to rule out whether it is the CPU that is causing failure of IBT.

[Ozzfest05]

my newest result

[Ozzfest05]

lower frequency but different ram strap and it produces way better result need to play around with this

[ci2kla]

Oh I've got an L832B716 as well but recently managed to get it to 471x8.5 rock solid using 1.2125v unfortunately I've made a stuipid decision to sell it to bad...
The new Q9650 L826B97* is really sucks 4.275Ghz with 1.375v ORTHOS will still cause reboots (test run overnight...) planning for further ultimate overvoltage and 7/24 use and hopfully be an and get it ***ed

I will keep at it. Please post here if you get any new results.

Can you post your BIOS settings?

[ci2kla]

Who say 500FSB on a quad is for P45 only? I'll show him

[ci2kla]

Can you post your BIOS settings?

you really need that? My settings are just for benching and cannot stand for 7/24 use...

BTW anyone with Q9550/Q9650 suffer from hard locks when trying higher FSB?
I've been getting frequent hard lockups (when press reset button need around 3 sec to shut down) anyone experienced? looks to me likely clock skew problem...

[Ozzfest05]

Whoohooo! I just need some cold now my water cooling isnt holding up this chip runs hot but I think It loves speed

keep it going Ozzfest you'll be sub-9s soon.

weather is warmer here so testing 4x1GB at the moment (sub-9m 32M is on hold )

BTW what was vCore for 5.1 max screen ? LLC or not ? cheers

[Ozzfest05]

the 5.1 was 1.49 volts with LLC enabled I tried LLC disabled with older bios and it didnt work currently using 1003 by didnt work I mean vdroop was horrid on 0503 If I had better ram sub 9 would be easier I wish I had those cellshock blues 1866 something that will do 2000 mhz at 7-7-7-20 would be sweet
