Better to leave it disabled if you can.

LLC is fine to use on 65nm.

[redrumy3]

hmm well for now i will leave it off to see what happens cause right now i have 1.55v in bios in windows it shows 1.50v under load it goes to 1.440v-1.45v so if this is stable then im fine, on my ip35 pro it took 1.45v for 3.6 so i hope this is fine i do like the board though over my abit i also put mch to 1.3v figured i might since im using 4 sticks of ram which is 8gb

but i think i need to ditch my ocz psu and grab a single rail corsair, just need to wait for money ocz is about 3 years old =]

[Phunky Phish]

I've answered that one. As for the temperatures, many new Core 2 CPUs have stuck sensors up until certain temp. You can use Tcase temp instead (HWMonitor, OCCT, Everest...).

Sorry Touche, I had 2 posts on that page.

Should have said look at my Bios settings!

Will edit now

Try LLC disabled and adjust vcore a bit if necessary.

Maybe set these yourself, instead of auto:

MCH/DRAM Ref...........................: [0.96] <===
ICH I/O................................: [1.500] <===
ICH Core...............................: [1.100] <===

You could try tweaking memory a bit with performance enhance Turbo and 266/333 memory straps, but it's not that important and you can leave it as it is if you want.

If you want to push it to its limits, look at Jor3lBR's template and go from there.

[radaja]

got a question,in prime95,if core 4 fails after one minute of blend what is the most likely cause?is it more vcore?or would it be mch? or something else? thanks

So you recommend taking them off auto and locking them to std values? I am at work so if those are higher a little I am sorry.

You mean these settings?

It being a 9650 wont make to much difference as mines a 9550 right?

[radaja]

in prime95 which fft size is cpu related and which is memory and NB related? thanks

Yes.

Those are the settings people have success with, but yours is 9550 an C1, so it maybe can't go as high.

[Leeghoofd]

Small : CPU
Blend : CPU, Ram and all the rest

[radaja]

so when first start prime95 using blend mode,the first set of test are small fft's?and if it fails right away,i need to up the vcore right? sorry for these stupid questions .thanks

[Leeghoofd]

Nope when you start blend it tests the rams and co first ( 1024K) when it passes there it goes to small and so on... first test the cpu with small ( as it can lead to fail the large test too ) and if the cpu is stable move on...

and mate there are no stupid questions, just stupid answers (and I'm the king of those lol)

[radaja]

thanks lee,that helps out alot.

[Touche]

Linpack is probably better for quick CPU testing. If it passes Linpack, go for Prime/OCCT blend/mix.

[Phunky Phish]

Those are the settings people have success with, but yours is 9550 an C1, so it maybe can't go as high.

I am happy with around 4Ghz.

Do you think with the multi on 7.5 I might make 533fsb and run the ram 1:1, or is that asking to much?

[bluestang]

Currently using Arctic Ceramique with my ZeroTherm Zen120 right now. I just got a Scythe SFF21G fan to replace ZeroTherm stock fan and some Arctic Silver 5. Anyone think it will make a difference? Also, any tips for applying/using the AS5 paste? Thanks!

[xbiusx]

Hi, i need some advices to reach over 500 FSB, now i`m stable at 500x8 but my intentions are reach 530x8 or the max as i can. But my first attempts were frustrating. With 510x8 i got my CPU stable ran ORTHOS 1h small FTT and no errors. But blend test gave error before 1min, so there is some wrong with my settings about the memory. And please take a look and let me know what can i do.

Didn`t work. I tried change one by one and when i changed DRAM termination i coundn`t boot... But i got better results than my first attemps, before i even ran 1 min on ORTHOS and now i run 7 min and got BSOD... So, there is something wrong yet

Its likely MCH ref or even MCH core that is holding you back. Run memtest and loop test #7. If you see tons of errors, raise the MCH core or even raise PL(static tRead) or your mem timings. If you get 1-2 errors in each pass then change the mch reff.

I just got my Q9650, So far I need different MCH ref settings and likely cpu reff settings for sure. I dont have much time tonight but will be looking back through this thread to try some settings.

Memtest passed 5 loops and no errors with updated settings (view settings above) Rised MCH core, and PL and loose some mem timings but ORTHOS Blend dosent work...


And now what can i try?

[Phunky Phish]

@ Bluestang RE Artic 5 paste.

Check out the website for good instructions on how to apply

I clean both cpu and heatsink with Isopropyl 1st
Then apply some to the heat sink, spread it and wipe it off with a lint free cloth
Then apply a very small amount to heat sink and spread it using the edge of a clean credit card or similar so even amount over top of cpu
Then fit heat sink!

If its a new cpu/heatsink combo I always remove the heatsink after fitting to check contact over entire cpu surface. If not then its time to lap something!!
If good, refit. You wont need to apply anymore paste, but I always clean and start from scratch.

[Touche]

I am happy with around 4Ghz.

Do you think with the multi on 7.5 I might make 533fsb and run the ram 1:1, or is that asking to much?

Your ram and the board are definitely capable of 533 1:1. You can try it, but there won't be noticable performance difference compared to your current settings, especially if you tweak your memory timings a bit.



xbiusx:
Lower DRAM termination and refferences (incl. MCH dram ref) to 1.000. Change CPU Thermal Monitor to Enabled. Have you tried all of the MCH ref.? If so (incl. those two steps up), try even lower settings. Then try to lower your memory divider so it works around 800 MHz and see if it's stable then.

[Phunky Phish]

So you recommend taking them off auto and locking them to std values? I am at work so if those are higher a little I am sorry.

Right, tried changing to these settings, wont boot into windows. It does the green bar then BSOD.

But the strange thing is I set it to the last clock that worked and all settings as post on pg 72 and it will not load windows, BSOD just after green bar.

Anyone any ideas?

Try to bring MCH ref up one or two step from default 0,760v.

[Phunky Phish]

Something is dead!

I have put all settings back to standard but it will not go into windows.

loads the green bar then BSOD, even on standard settings.

Running memtest to check the ram. If it passes will clear the bios and try from there.

[mattlyall06]

hi all,

what a useful and informative thread. been reading for a while now, first time post. once i receive my tax return i shall be purchasing a UD3R + Q9550, already got myself a TRUE and i just lapped it. my goal is a 4ghz 24/7, and id assume i should have no problem getting there...?

the bios templates are sooooo useful, as im very confused about the many extra features that the P45 chipset has over the P35. coming from an EP35-DS3L it seems to be a little daunting the amount of more features this board has. i understand that the cpu ref, Vtt, cpu pul, mch ref are very important when it comes to stability, but im just not sure how im going to go about setting these values. is it just trial and error like the rest of the overclocking process? if theres one thing i notice in similarity between all the templates ive seen is that the values of these things have been increased from stock, never decreased. but, from one of the stickys here, i see that there is a whole process to determining these values. again, are these values stock that vary from board to board? i guess what im really asking is, how will i know what these should be set to. if i has to guess i'd say that im just gonna have to play around with em and see what gets me the most stable.

my soon to be rig:

-UD3R
-Q9550
-TRUE (lapped) w/ scythe ultra kaze 3000rpm
-mushkin 2x2gb ddr2 1066 5-5-5-15 2.0 - 2.1v
-evga 9800gtx+
-cooler master cm690 case

watercooling Cpu block Fuzion with quad nozzle and pro mount

so those settings are good for 24/7 ?

i can do 4ghz but i dont like the volts i have to give it =/ so 3.6 is enough until i go i7 or 9650 etc
