The thing is i can get it stable at this and pass the intel burntest ,but the v.core is high if i drop it down it will only last 3 mins on intel burntest ,running at this voltage the temps are around 80 deg which is high ,normally temps are about 30deg is this very high for the intel burntest and is there anything i can do to get it stable without having the voltage up so high any help is much appreciated

My system is

Sapphire Radeon HD4870 1 gig

What stepping is your 9550? If its CO then that may be as good as it gets, but likely you can get lower volts. From what others have said/found the quad cores(9550/9650) seem to like CPU reference and mch reference) of .80V, shown in ET6.

How you set this is like follows:
Set VTT(cpu termination) to 1.20v(stock), then set the references mentioned to .80v, then raise the VTT back to what you need or had it at, so 1.30V.

Re: Help to overclocking a q9550 ga-ep45-ud3p

I have the same processor/mobo combo (also a C0) and i'm running 471x8.5 currently. I too am looking for the sweet spot on voltage. Without LLC it seems you have to go 1.4+ and from what i know it isn't a good idea =/

Re: Help to overclocking a q9550 ga-ep45-ud3p

hi thank for response it is a EO stepping

Re: Help to overclocking a q9550 ga-ep45-ud3p

Thanks everyone for your help,i have adjusted my settings to these belowand the max temp it went to on intel burn was 66 deg so im really happy
If there is anything really not good in these settings could someone please say,again thanks for your help

Re: Help to overclocking a q9550 ga-ep45-ud3p

Looks good!

Test with ICH and ICH I/O on stock voltage as you may not need more, but maybe you do??

Other that that looks fine.

Re: Help to overclocking a q9550 ga-ep45-ud3p

Thanks speedeuphoria
Just tested it with stock ICH and ICH I/O and it passed fine
Thanks again for advice

Re: Help to overclocking a q9550 ga-ep45-ud3p

I just got my Q9650 installed today so I'll be testing tomorrow. Then I can try some settings.

SpeedEuphoria,

What is XP SP3 slipstream?. You have Vista 64 SP1 on your new build list? Can you tell me about what you are doing. I just stepped onto the learning curve here...

Re: Help to overclocking a q9550 ga-ep45-ud3p

Hi andypepp,

Don't you want your dram freq and your fsb to have a 1:1 ratio? Would prevent a bottleneck. I think you should increase your dram freq to 900MHz. Your memory latch (MCH Freq Latch) should be at 400 instead of auto. If I'm wrong, please correct me.

Also, you should try bringing down your memory timings to 4, 4, 4, 12 from 5, 5, 5, 15.

Then again, that 1:1 ratio may only apply to AMD boards. I just had to throw that out there.

Re: Help to overclocking a q9550 ga-ep45-ud3p

I used a Q6600 with the same board as yours, ep45-ud3p. Here are my results

Maybe this can help a little.

SpeedEuphoria,

A slipstream, is taking your windows CD/DVD and copying it onto your hard drive. Then like if you had an XP service pack 1 cd and didnt want to go through all of the automatic updates to get it to service pack 3. So you use a program nlite or similar to install the service pack onto the copy on your computer. Then you burn a new install CD. Its a lot faster if you have to install your OS again.

You can do many other things, like add programs that you always use into the install CD. Or remove windows programs that you dont use. Or you can make it "unattended" which you input all of your info into it, so you dont have to type your name/region and the CD key in everytime, makes it so you just put the cd in and walk away, when you come back it will be fully installed with no input from you.

If you want more info check this forum for starters:
MSFN Forums

Here's there guide:
MSFN's Unattended Windows : Unattended Windows Introduction


Anyway I have some testing to do tonight, so far the Q9650 is a beast and booted right up at 480x9.


It failed OCCT after 30min so I have to tweak the CPU ref /MCH ref as well as maybe VTT and MCH core till I find the sweet spot.


So far it needs higher VTT and MCH/MCH ref than my E8400. But it does the same clocks on the same Vcore, just runs hotter

Re: Help to overclocking a q9550 ga-ep45-ud3p

hello everyone, i'm new with this overeclocking thing, and i have the same processor and same MOBO as this person...i did everything exactly the same as him/her, besides this part that i didn't think wud matter that much...

Fine CPU Clock Ratio............................[ + 0.0 ]
CPU Frequency 3.8GHz............................[ 475 x 8.0 ]

my cpu clock ratio by default was [ + 0.5] so i didn't change it, and frequency was 4.02ghz [475 X 8.5]

i also left ICH and ICH I/O voltage at stock cuz andy said that his system passed @ stock.

THE PROBLEM IS WHEN I RESTARTED THE COMPUTER...IT KEEPS ON RESTARTING, AND DOES NOT EVEN ALLOW ME TO GO TO BIOS to change anything...what did i do wrong, and how can i fix it? any help would be greatly appriciated.
