Retail Q9650 Overclocking Thread

[nugzo]

I've had this CPU 2 days and this motherboard (Maximus II Formula P45) came in today. I'm new to intel chip sets so most settings are on auto. I'm pleased with what i have so far. This isnt tested long term for stability but i've had no issues at all so far. I went ahead ant posted in hopes for some suggestions. Vcore can probably go lower, this was just my starting point. I'm down for any criticism if i set something stupid in bios. The nforces ive been OC'ing for the past 3 years are a lot different.

Really nice Q9650 you have there!

Same batch as napalms?

Thanks and yes, same. Not the same skills though

[SNiiPE_DoGG]

I think one addition to this killer combo is the p45+q9650. x38 is giving me no love (except for 4.1ghz)

[zlojack]

Napalm, adjusting the v12 is a hardware mod, right?

[funkflix]

Normally yes, but some psu have varibale resistors inside. With this you can manually adjust the rails. But don't know how napalm realised that.

On the other side, i can't see any advantage in rising the rails over the demanding 12.00V. Maybe if you use a poor psu, which drops way under maybe 11.90V it could possibly a advantage. But to be honest i don't think anyone here in the thread will not have have a state of the art psu.

Played a lot with adjustable rails in the past, but if some component is holding back the oc i couldn't get them higher with raising the rails. It was just to get the placebo effect of higher and "stable" voltages. But i always used some of the best psu you can get at that time.

[zlojack]

I know my PSU has a switch that changes from various 12v rails to a single.

I suppose I should have it on the single for better OC results?

[funkflix]

Possibly it could have a positive effect. But don't think so. Your silverstone have 2 x 17A for supporting the cpu. 34A x 12V = 408W. My Q9650 need about 9.8A with 4000MHz 1.27V while priming.

PS.: But i would always prefer single rail mode.

[bigslappy]

single rail period !

bingo! yatzeee!

ill say it once again.. best shot at high quad fsb/clocks = P35/P45 especially P45 but even some great P35 mobos could reach P45 clocks

And having the proc under phase doesn't seem to hurt anything either

Got mine @ 4.25 1.35v 24/7 on my EVGA 790i Ultra. I piece of cake. Still haven't moved it over to the 790 FTW yet. Should be able to push it a little higher.

andyc

FYI and others .. as far as max oc goes i gained just 100mhz from air to phase @ max vtt/vnb

loads are different 4.5ghz to 4.9ghz

Napalm, adjusting the v12 is a hardware mod, right?

correct.. adjusting v12 means adjusting v12 pot @ psu

i would advise against such mod.. have it done by someone experienced

thats the mystery? maybe cause ive been doing for quite some time.. dont believe me? go ask the other more trusted better known ocers about psu..


the most important part at hard ocing is the psu

[road-runner]

I cant seem to get my Q9650 over 515 x 9, P45 Gigabyte board...

1. That part you wrote in bold was pertained to the modded +12V rail on your psu.

2. Do you know how all that voltages act togehter with oc? A example: Your psu have 12.00V and cpu needs 150W, then you have a amperage of 12.5A. If you have your rail pushed to 12.50V you will have a amperage of 12.0A. Now tell me, which one of this is better?

3. If you want a good psu for oc, you do not need higher voltages on rails then the needed 12.0V for example. You need stable voltages, no flucation, good regulation, good filtering, close to no ripple and all that stuff..

But let's stop now. If u just can "lough" about what i write, i don't want to "discuss" with you. Never said anything bad about your results.. just doubting on your high rails theorie.

darn! such low fsb and clocks for a quad!

[nugzo]

Yeah me too. I can get 615 but not 620

lets do it right here.. not @ pm.. for everyone to see

post your voltages/settings.. please

also what kind of cooling/psu/mobo/ram

dont take it so serious.. sounded funny

no theories no bs its a fact and i didnt come up with it on my own

how do you think you see so many extreme clocks posted by great overclockers? @ v12.0 straight? never

[Utnorris]

NapalmV5,
You never seize to amaze me. You could have just posted your numbers and left it at that, but instead you are willing to give some of us light weights help, so kudos to you for spreading the knowledge. Hopefully, when I get my Maximus up and running I can come back here and post some credible numbers.

Again, thank you for all the help, both private and public.

[SNiiPE_DoGG]

So as I have never heard about this with any PSU reviews or users posting... what PSU's have VR's to adjust the rails, I'm willing to open up my PSU as long as I know what I'm looking for and roughly where it should be....

just checked my main rig and the HX1000 has the 12v rail down at 11.71v (via Everest 4.6)

[funkflix]

Just measure your +12V with a DMM. HX1000 would never just give you 11.70V with that kind of load your system have. If so, it is defect.

Please do not even think of modding your HX1000.. It will hold every overclock on your cpu without any modding. Believe me.

GA EP45 DS4P, 2GB Kingston 8500, PC Power & Cooling 750w, Dtek Fuzion, Laing D5 Basic, Swiftech MCR220-QP, 2-3870x2 stock cooling.

Bios is all auto settings except vcore set to 1.575 in bios and 2.2v on RAM 5-5-5-15 rest on auto, 2.00D/400/Standard, had to add a couple increments of voltage to ICH core and I/O to post. I can bench at 4599 but no higher...

[zlojack]

correct.. adjusting v12 means adjusting v12 pot @ psu

Well, if I get someone "more experienced" than me to do it, I'll never learn.

But if someone more experienced showed me how, I might be able to do it.

Anyway, I'm not sure how much PSU modding I want to do. Mine has no warranty anyway, so I guess it doesn't make much difference

[road-runner]

This is what easytune reports...

[nugzo]

I guess temps are way out of line, thats why no prime screen with temps? It certainly wont last long at those voltages.

[NapalmV5]

road-runner

that easytune ss is easier to work with.. thanks

before you go any further what is your v12 @ those clocks/settings?

pll is too high
leave vcore as is
vdimm/vnb are way way low which is a good thing.. more headroom

set vtt @ ~1.8-1.9
set vpll/vi/o @ same voltage 1.6-1.7
set vdimm @ ~2.5-2.8
set vnb @ ~1.7 all the way @ max if you have to
set cpu clock drive @ 1000mV
set pcie clock drive @ 1000mV

523x9 easy
534x9 doable
545x9 within your grasp @ max vtt/vnb


since im waiting on new ram im back on air so ill oc with you

[road-runner]

Voltage at 4ghz according to easytune is 11.921 run it 4Ghz 1.45 vcore setting 1.328 real under load. That was just trying to run a quick bench. I am not sure whick setting is vtt vpll/vi/o as I was just used to the P35 boards where all you had to set was mch and fsb. This is what it has been running 24/7 cruching...

[NapalmV5]

1.45 @ 4ghz is too much

1.3vcore/1.3vtt should run it stable @ 450x9


did you oc via easytune or bios?
