The E0 Q9550 SLB9V thread (finally!)

[pezcore]

Man, some of you guys get to use low voltages.

<--jealous

I downloaded Core Temp to see what mine was, and I get 1.2625, which explains why I'm at 1.4v for my 4.0GHz. Oh well, I still idle at 40*C

[Kashelz]

Take the Gigabyte P45 UD3R or P45 UD3P, really great board for 45nm Quad CPU, got mine and went from max 450 FSB to 510+ fsb that is Linx Ok. Got from 3.8 to 4.3 Ghz for 24/7. Old one was Asus P35 P5K-E, that was good with 65nm Quads.

[MrDucky]

Well i clocked my Q9550 E0 vid of 1.1375 to 4GHz @ 1.23 Volts with 500FSB but as soon as i change 1 thing on my GTL settings exept my NB it will not boot so i think if i had a Gigabyte UD3P i would have a higher clock. but maybe i need to try another bios so il be trying the newest soon

[Unrealer]

Take the Gigabyte P45 UD3R or P45 UD3P, really great board for 45nm Quad CPU, got mine and went from max 450 FSB to 510+ fsb that is Linx Ok. Got from 3.8 to 4.3 Ghz for 24/7. Old one was Asus P35 P5K-E, that was good with 65nm Quads.

Wow, thats a nice change... so, did u use the same vcore and nb voltage for that oc?

[MrDucky]

my max fsb is 520 on my DFI Mobo thats stable but i need much higher vcore cause i didnt test the GTL voltages but look at the Q9650 tread you will see that every one that has a UD3P has realy good OC's with the Quads its famous for Quads still i like my DK P45-T2RS+ i just need to take some more time and since its weekend now updating bios

[Gaul]

@ unrealer = low vid, high vcore ? compare with mine ....something wrong with that ?

[Unrealer]

@ unrealer = low vid, high vcore ? compare with mine ....something wrong with that ?

What do u mean?

[pezcore]

Is there a difference/benefit to using 500x8 instead of 471x8.5?

[Gaul]

What do u mean?

many said, lower vid, meant lower volt for 4 GH.......or better OC

well, see

u had vid 1.125, need 1.3v for 4 GH

mine vid 1.265, only need 1.25v for 4 GH


@ all = 4.25 GH for 1.32 v

[MrDucky]

@ pezcore with Higher FSB More data can be send over the northbridge so your Memory is a little faster and for example if u use Crossfire like i do you need the Brandwith to support the Graphic cards so 500x8 is better for me..

@Gaul well Low VID means most of the times better OC or lower Voltage at same clock but she has P35 chipset thats not the best platform for a Quadcore for example if u use a Gigabyte UD3P or Her mobo DFI P35 the Gigabyte would clock much higher on lower clock simply cause the P45 can have higher FSB and has more Settings. so my question What mobo do you use?

[Gaul]

ic...ic, my mistake..mine UD3R sorry

I see. Well I am using a GTX295, so would 500x8 be better for me?

Can I just change it to that without messing with other things? (voltage, etc.)

[Unrealer]

many said, lower vid, meant lower volt for 4 GH.......or better OC

well, see

u had vid 1.125, need 1.3v for 4 GH

mine vid 1.265, only need 1.25v for 4 GH

I tested SIX Q9550 E0 with this mobo, the lowest VID was 1.1x and i couldnt get 4Ghz stable with 1.35v, the other five are stable with that vcore.

[MrDucky]

@Gaul well then your lucky i guess that you have such a good mobo :P

@pezcore

well try it and test with 3dmark but i guess 16x 2.0 is enough for your GTX295.
Look i have 2 HD4850's and in Crossfire my link is set to 16x 2.0 and 8x 2.0 so for my second card i want to get more brandwith and its an massive change in 3dmark it costs me more then 1k if i do 471 or 500...

[pezcore]

I tried 500x8 and it wouldn't even boot so I put it back

[Gaul]

I tested SIX Q9550 E0 with this mobo, the lowest VID was 1.1x and i couldnt get 4Ghz stable with 1.35v, the other five are stable with that vcore.

yup, all because u'r mobo.sorry

@Gaul well then your lucky i guess that you have such a good mobo :P

THANX man....!!

let's me introduce u

Q9550 @ 4.25 GH v 1.35, prime for 3 hours

[phsinc1]

yup, all because u'r mobo.sorry



THANX man....!!

let's me introduce u

Q9550 @ 4.25 GH v 1.35, prime for 3 hours

can you put full template for your settings? and what bios do you use?

[Kashelz]

You can and can not get 4 Ghz stable? It all depends on FSB and GLT voltage, that’s all

My old P35 board was great with Q6600, it did 480 x 8 with no problems for 24/7, so board was good for 480 fsb, but with 45nm Quad id did only 450, no more. Asus P5K-E have really bad settings for GLT voltage (only 4 settings), so there is no chance to get something good, with Giga P45 UD3R/UDRP it is different story

At first posts I could not get 4 Ghz ok, but after some time of testing and tweaking BIOS I went to 4.2+ Ghz that max Linx ok. After all I can say that GLT voltage is the key for high fsb and also FSB voltage. Even high vcore is not needed as it was with 65nm quads.

[Gaul]

can you put full template for your settings? and what bios do you use?

templates ? later.....BIOS, default from factory F11.....

[bigwill68]

aight fellows. i hav'en posted here in awhile picked up a UD3P slaped the Quad 9550 EO to see what it can do here's a shot a 4.2ghz passed IBT vcore set at 1.387v droop to 1.360v...I forgot was the rest of my setting did'nt record them at the tiime and ET6 was'nt install yet.I've been resting at 3.935Ghz for awhile with the vcore at 1.268v set in the (Mit) no problems passing IBT now here also the setting to reach 4.2ghz

Gaul has incredible results in his out come of Oc'ing at low volts.I wonder is there something.I'm doin wrong to get that? I can't remember what board he got it's not posted in his sign

Are you sure your even on PL8 now? The lowest you should be able to go on 2.00B is PL10 with CAS 5 and PL9 with CAS 4, 2.00D will let you drop to PL9 with CAS 5 and PL 8 with CAS 4.

Do you need such a high CPU Term Volt. and MCH Voltage for this overclock?

[bigwill68]

Are you sure your even on PL8 now? The lowest you should be able to go on 2.00B is PL10 with CAS 5 and PL9 with CAS 4, 2.00D will let you drop to PL9 with CAS 5 and PL 8 with CAS 4.

the lowest my System Memory Multiplier will go is 2.00B and your saying Only cas4 memory will you let drop to PL9? if you would post a code I'll try to run of it and test and post the results and see how...I come out

Never tryed lowing it what would you recommend and good trying setting to test?

@ bigwill = we have similiar templates 4 q9550 @ 4.25 GH here........

anyway ? there is different : PCI Express Frequency (Mhz) ..............: 101
than 100 MHZ ?? cause im still 100
