Installed a P5Q Deluxe tonight hoping to get more than the 465FSB on my X38, its not looking good. I can just about boot at 470 but no more. It also fails prime blend around 460fsb. I thought these P45 were supposed to be the FSB kings.

Sorry to go off topic here :
@Devious : They are, but your ram isn't really liked by the board... have you tried 1406 bios ? 500FSB was really no issue on my 2 boards with the quad...with Mushkin and Gskill PC8000 ram 1081Mhz is absolutely no issue, Mushins 4gb kit can even do 1120mhz... the reapers I had were troublesome...

I had the p5q dlx and it would not get my q9650 over 455 stable tried everything ended badly killing my 9800 gx2, had to reinstall windows 3 time and the memory hole we wont go there. As well as never wanted to boot first time. Wait or anytime to be honest tried all the bios even a default never wanted to play. Good luck! I went for the evga 780i not had a problem since booted first time @ 4.050 and screams though every game save youself time and money and send it back.Quote:

Can I ask what settings you have used ?

I wonder if there is a board out there to get this to 500fsb ? I thinking this is more of a cpu wall, shame if it is as its using no vcore for high clocks.
Yeah they are ! checkout those links i post beforeQuote:

I will be waiting anxiously for your results. I'm sitting here with a MIIF, RE, P7NDiamond and EVGA 780iFTW that i've been testing with this 9650. Even with lower multis the best i can get stable (3hours small fft so far) is 467(1868) FSB (4200mhz) and thats on the EVGA that i got from the egg today. It has issues though and wont detect my xonar. Cant wait for my SIIF to get back from RMA. I had 475(1900) running on the RE but cant confirm stability over 1 hour prime95. I was so anxious to get this 780i in that i didn't test that X48 thorough enough. SLI keeps calling my name so i'm trying to find a reason to go back to nforce. 500FSB on that Gigabyte your linking would slow me down some though. Please let me know how it works out with the 9650. ThanksQuote:

The rest of the info is in my sig....
Love the Q9650, what a sweet chip!
I found the key to stability at an FSB of over 475 was gained by tweaking the GTL refs. For example, when I found a sweet combination of fsb tem voltage and gtl ref it was prime stable, but if I changed both of them so that the same end value (vtt*gtl) was being used then the system wouldn't be stable. I don't understand enough to explain why this is so, but it did take ages to find a decent combination of vtt and gtl ref. Also, adjusing my clock skew seemed to help. I'm struggling to get stable at anything above 480 but Brolloks over on ocforums is stable at 490 (x48 board). I can get it to post at 499 but anything over 500 is proving less easy. Probably something needs to be tweaked!
I'm at the edge of what I consider safe voltage (~1.4v vcore and vtt) though so I don't have a lot of headroom to feed it more. Can't afford to kill this q9650! Not yet anyway.
Nice to see that GTL's helped on your situation, Can you tell me wich value did you end as VTT x GTL ?Quote:

Im skeptical about those results in the links but I look forwards to see if it helps you on Friday.Quote:

could anyone tell me where to get the new bios for the evga 780i I can't find them I'm currently running no5 but the vdroop is huge like I'll set it at 1.40 in bios and get 1.37 in windows and 1.32 at load which I'm worried about my chip having to many volts so can't go higher and if anyone knows what the other voltage setting are for as they don't say nb and sb
Yea Bigslappy. I'm interested to see your results with the UD3 and the Q9650.. Please post asap when you get her going.
also system Viper.. In your sig I see you have the Giga 45-UD3P.. thats the new Ultra Durable that Fugger was saying he got a 540 FSB with.. on the QX9650.. you have it, with a Q9650. Would you possibly wanna see how high you can overclock that thing.. I see you have more than one Q9650. Sure would be nice. I wish I had a second one. I love them. lol.
Also Guys. I had a question still not answered. Do you guys when saying this is how much voltage I needed. or when you say the safe voltage is 1.3625v is that in BIOS. or in CPU-Z. like right now for 4.0 Ghz stable I'm at 1.3312v in BIOS. but in CPU-Z thats 1.296v I see many people's Sig's saying I'm stable at this speed with this voltage. and it's the CPU-Z voltage. So is that what I should go on. as thats what my CPU is actually getting. So as long as CPU-Z is under 1.3625 I'm ok. or should I stay under that in the BIOS..?? Please let me know someone.. Thanks.
whatever CPU-Z shows is what you should believe! Think of the BIOS setting more as a guide to where it might be!
Oh ok, great. Thanks. so like yours.. your at 4.3 Ghz at 1.4v but it's higher than that in BIOS.. but ur taking the 1.4v and saying that cuz thats what it reads in CPU-Z. cool thanks for the info
Also what are your idle, load temps at 1.4v with that on ur true? and whats ur FSB/VTT voltage?
xguntherc i got your pm but..
how can i help you/anyone else if you guys dont want to go over certain voltages.. ? :shrug:Quote:

look guys.. when it comes to hard overclocking.. throw your brand loyalties out the window.. ive napalmed asus myself but to each his own.. :)
if you guys want high clocks/fsb stop believing cpu/volts myths.. that would be a start :up:
and for goodness sake adjust your psus.. you guys want to listen to someone at 4ghz-4.5ghz or listen to someone at 5ghz ? up to you.. but if you have to ask me how to adjust the psu rail/s.. im very hesitant to say the least.. but im willing to help anyways..
everything ive posted in this very thread is OC 101.. some have to skooled when it comes to ocing and im not referring to the "light weights" as put by utnorris
p45 mobo suggestion: beefy R80 chokes.. ep45 dq6/extreme features 12 x R80 chokes.. why do you guys think i can clock up to 4.9ghz on air besides voltages ?
to sustain/to even os boot @ 4.8ghz psu v12 @ no less than 12.5
if your psu is made by iron man tony stark.. well maybe then youll be able to run 5ghz quad @ 12v straight
and dont worry.. i will help as much as i can even if i have to deal with ego inflated jealous *******s :)
post all your Qs here publicly so others will see/learn/pick up/etc..
please adjust psu rails at your own risk
be sure you know whats involved
loss of warranty/psu
loss of parts due to high voltages
heres a procedure on how to adjust/monitor your psus rail/s..
open up your psu if you cant adjust v12 from the outside..
look for the v12 pot.. if yours features just 1 pot.. it is most likely the v12 pot.. turn clockwise left to right.. how much? well now that is the Q.. just an itzi bitzi bit.. but enough to turn the pot at least.. maybe you have a variable pot around to practice on so you get a feel.. better yet how about a guide to get you guys started:
http://www.xtremesystems.org/forums/...ad.php?t=37574 courtesy of Hell-Fire
hook up the psu to the mobo.. thats it just the mobo+psu
hook up your multimeter to the psu negative.. the 4pin peripheral connector will do.. to monitor 12v rail: yellow end + to monitor 5v rail: red end @ 4pin peripheral connector.. 12v monitoring also @ pcie connectors.. to monitor 3.3v rail: orange wire @ back of sata connector
but id say just adjust/monitor v12 for starters.. enough to get the most out of your mobo.. 5v and 3.3v as a last resort.. if its a beefy/well made psu you wont have to worry about 5v and 3.3v the psu will take care of that by itself
alright.. power up! while staring at your multimeter.. if ~12.5 its fine
if its higher than that.. shut down immediately!
turn down the v12 pot.. power up again.. if its within 12.5 your fine.. if its higher.. shut down immediately!.. turn some more down
if your @ 12.4 no problem.. leave it as is.. you can adjust it later
install cpu
power up! if your v12 rail doesnt drop more .05 leave it as is
install your ram
power up! if your v12 rail doesnt drop more than .05 leave as is
install your vga
power up! if your v12 rail doesnt drop more than .05 leave it as is
install everything else
power up! if your v12 drops to 12.4 from 12.5 @ mobo+psu its fine leave it as is and continue with your oc
if want to go for more v12 after your highest oc.. increase your v12 a bit more so that @ your highest oc your system is @ no less than 12.4-12.45
oh and this is @ 1000watt beefy psu like the OP1000 ;) even the OP1200 :)
please adjust psu rails at your own risk
be sure you know whats involved
loss of warranty/psu
loss of parts due to high voltages
Awesome.. Thanks for responding to me. and posting for everyone to get the info.. I read Hellfires thead. very informative.
I have the Corsair HX520.. I've heard they have good PSU's.. it shows 11.92 in BIOS.. Do I have to add the VR's or do some newer PSU's have the Pot like you mentioned.. hopefully I can just open it and turn from there.. Also is there any way I can check it without it being hooked up to anything other than the Voltage Meter. just to be safe on my parts.
edit* also Napalm. I am willing to go over those voltage marks.. I just don't want to kill my chip., but I guess thats the risk we take in wanting the best performance we can get. right. I did have a question for you. what did you decide on for your Q9650's 24/7 usage? and what FSB/VTT you using. don't tell us all the rest of the settings though. there "needs" to be a little trial and error right.
@ Napalm, do you think your chip would have gone over 500FSB without the mods to you PSU ?
Im not going to be modding mine and just wondered if i should give up trying new mobo's to get to 500FSB.
I don't know my idle temps, but my loads temps are about 69/70C. My vtt is set to 1.36 with the gtl ref 0/2 set to 0.65. If I change either setting by one notch I lose stability. Getting stable at 490+ is definitely possible but will probably require lots and lots of time to tweak it and the possibility of slightly higher voltages.
Out of interested I've just checked my 12v and it's running at 11.88 or 11.93 depending on load. I wonder if that's holding back stability...
Do you guys think a Q9650 @ 4Ghz+ should last in a top spec gaming pc till 32nm Nehalem/Westmere is out in 2010
of course will be updating my graphics card often
or should i just keep my Q6600 @ 3.6Ghz
the problem is im starting a masters degree and i dont want to be distracted with constant PC upgrades
i would like to build a pc NOW and be happy with the performance for the next 2 years so i can focus all my time on my studies
If you want something new to play with then the Q9650 is awesome, but in all actuality the q6600 should be ok for awhile...in terms of games and things the difference is not very significant yet ......also I'm on a motorsport engineering master's course and yet I still am distracted by puter stuffs :/
@NapalmV5 thats gold right there :up:

Soo yeah get the Q9650 & yer good till the software makers catch up to the i7's >32nm Nehalem/Westmere> LOL the hardware to support that Q9650 is dropping by the day ............ Go water !!
I'd get the Q9650.. it's cooler like Big said.. it's something new you can play with for a while. and it will for SURE last you with top performance til 2010.. I mean look at when the Q6600's first came out. they are still great. and even though the Q9650 isn't way way better.. YET. but soon it will be. they already get 10% increase in performance clock for clock over the 65nm chips. I'd get one. and when games and such catch up. you'll have one of the best til 32nm Neh comes out.. thats what I'm doing.. Waiting for 32nm Nehalem. and I'm pretty sure this will last me.
also pascal. I'm wondering the same thing about mine. I have a Q9650 at 4.0 Ghz, and a GTX260 fully overclocked.. 7 120mm fans, 2 22's and everything in my sig, all working off my HX520. I'm wondering if I'm getting pretty close for this thing? I wonder if the HX620 would give me better results as it's more efficient on the 12v rails... and weather I'm at idle, or load. my 12v rail stays at 11.92.. so I'm not sure if thats causing it either.. good question. Maybe Napalm can answer that. I do know without modding them to 12.4 like he said.. 4.5 ghz and above will be very hard to hit without serious voltage and water.!
