Retail Q9650 Overclocking Thread

[systemviper]

I rocked my
Q9650 to 4GHZ @ 1.28v

Next I will see how high she can fly...

The rest of the info is in my sig....

Love the Q9650, what a sweet chip!

[pascalbrown]

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 ?

Becouse its nice to see does any of those formulas about GTL be right, as the say Vtt x GTL should be 0.8-1.1 !

[Devious]

Yeah they are ! checkout those links i post before

540 FSB on air with a GigabitEP45-UD3P ! And that's with a QX9650 bet the Q9650 can pass that !
we'll find out on Friday when i get my board & memory ...................

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

GTL REF 0/2 set to 0.650 and the vtt at 1.36. This is for stability at 475. If I change either of those values by one increment i lose stability. Strange, but true!

I want to get stable at 490+ though. Don't know if I dare increase voltages anymore.

[davidoff619]

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

[xguntherc]

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.

[pascalbrown]

whatever CPU-Z shows is what you should believe! Think of the BIOS setting more as a guide to where it might be!

[xguntherc]

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?

[NapalmV5]

xguntherc i got your pm but..

Ya that could be possible, I'm not sure by how much. as they have the same architecture right?

that would be an interesting thing to try and see. I'm wondering how long some of ours will last if we gave them 1.5 FSB/VTT even though I'm not going to go much higher than 1.4v on VTT on mine. Don't wanna risk it yet.

how can i help you/anyone else if you guys dont want to go over certain voltages.. ?


some of you live and die by the asus brand.. fine.. so you shall be stuck at low quad fsb..


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

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..

[NapalmV5]

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

[xguntherc]

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.

[Devious]

@ 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.

[pascalbrown]

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

[gurusan]

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 :/

[Jor3lBR]

@NapalmV5 thats gold right there

TEMPS it's all about temps......... IMO
the Q9650 Runs way cool next to that Toaster of a Q6600 & we still have head room on the O/C'in the Q9650 @ 4GHz still looking for it's sweet spot !
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 !!

[xguntherc]

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.!

P45-UD3P came today, 9650 arrives tomorrow

I'll be taking it easy on the cpu for the first few days, but I can post batch#(ordered it from the Egg.) and prelim results.

[davidoff619]

right guys i decided to stop at 4ghz for the time being which will benifit gaming more
500 x 8
or
475 x 8.5
or
450 x 9

cpu temps are not a problem at 450 x 9 @ 1.336 vcore. 6 hours prime stable max core temp is 53.

and get this using ocz flex 9200 4gb kit was able to get 1200mhz 4-4-4-14 @2.15v

Bah!

Has no-one got both the P45-UD3P and a Q9650 yet ? It always seems to be one or the other.

The suspense is killing me

I got the P45-ud3P & my Q9650 up & running last nite loadded on a new setup & hhd ,OS Vista64 water block CPU only loop

BUT HELL I'm used to asus Bios so the learning curve is steep with the Gigabite Bios screens & I need to flash the Bios that HiCooke is using, Soo give me a chance to laern afew tricks with Gigabite any help would be Greatly in Thanks From This Guy !!

it's a VERY NICE BOARD ! booted right up No Problemo !

even ordered another Q9650 & am selling my QX9770
