I just got my E8500 C0 to 600FSB on my SS unit.

I feel that 625FSB on a E0 would be easy.

what kind of bios settings did 600fsb need?im having a very hard time getting 550fsb.it wont get past the memory test screen.

[xzulu]

yes on my system i have to go for 1,4MCH as im always over 1170Mhz with the Gskill on Turbo Profile, if i remember you are on turbo profile also mate, maybe it can handle it good if you go for standard, but with thight timmings it'll ask for more at least in my case...

cheers
Sergio

Yup, you're right. Thanks!

[OC Nub]

Was able to get 4050mhz to pass LinX but took 1.30v bios. Not a super clocker for sure but I will keep going up, temps are great compared to the quads. Stuck idle sensor on both cores but under load seem fine.

Thanks for the help radaja

[radaja]

no problem.good luck tweaking it.

[OC Nub]

4.2ghz 1.343v bios. Other voltages the same. Had to switch out the mem, new ballistix 1066 are junk for oc'ing.

I'm using the F9 BIOS with these settings:

VTT: 1.4V
PLL: 1.59V
CPU REF: 0.856V
MCH: 1.56V
MCH REF: 0.826V

I got them from 7ornado's post on i4memory

Nice!! Another great OC! and nice chip!

[OC Nub]

I love this Motherboard but I think I like the p35 better for ease of overclocking with a core2dou. My P5Kdeluxe would do 500fsb stable on default/stock board voltages no tweaking needed. I'm sure this board would allow for better max fsb but needs a lot of tweaking.

[clo007]

xzulu, have you had any trouble running ram in dual channel at all? We have almost same proc/ram combo/PSU and I was curious if you had an issues. To this day, on my 3rd UD3R, I can only run single channel memory and I don't have the money/time to RMA this board.

here are my new update with water Q9650@4,2ghz

[BuGjAE]

Hi Panging, I don't post in this thread for a while because I play around with P5Q -Deluxe , but eventually I 'v been sold it and buy new UD3R Rev 1.1 ,and wanna share quiet stable result ,one thing that I think this is the really great for this board is it can do PL 9 with FSB 550 1:1 Dram that It cannot possible with P5Q Deluxe even boot up. then get the great score on EVEREST! and Winrar Extraction without CRC Error.
I feel that 550 FSB doen't need high VTT like I setting it only 1.20
If I set it over around 1.24-1.26 It 'll become CRC error on WINRAR Extract with unknown reason.


And anyway I still don't know why I can't OC well with my Ud3P??

[radaja]

very nice BuGjAE!

clo007,have you tried a new set of ram?i mean a set that you havent tried on the previous three boards.cause i cant believe you have had such bad luck as to get three boards with the same problem.i know you have tried several kits of ram,but have you bought and tried a brand new kit.i can send you my cheap ddr2-800 g.skills that work great on my new board,they OC to 1066 with ease.no charge.i'll give them to you.just pm me your shipping info.if your interested.it's this kit in the link below.

LMK ok.

Hey dude, nope I never had problems at all. Stable as a rock.

I just had to set the vdimm in the Bios to 1.92v cause in windows it runs at 1.89 if i set it at 1.9v in the Bios.

What problems do you encounter?

[bluestang]

bluestang post some results with that memory and tell us if they are D9. I think u are getting 2x1GB sticks.

kagula, I just got done stress testing this setup. Temp in room with PC is at 27C right now...How do my temps look for this setup. Do I have a hot or cool chip? Time to shoot for 8.5x500 for some better performance. I still haven't taken memory out to check what chips are used...too afraid! LOL

[OC Nub]

Put my old 8400co in, Batch#Q745A357. Much better than the eo I just got. 1.225vid cpu. Had to use 200d, don't have any 4gb kits that will do 1200.

[radaja]

yes indeed,thats pretty damn good.

[OC Nub]

Thanks radaja, was hoping for a dual core that would let me run 4.4-4.5ghz 24/7 but don't think its going to happen. I have no idea what the temps are on this Co, at idle both cores read 20c no matter what voltage. I adjusted the temps in real temp to show 32c idle, they do go up evenly but without the adjustment they only hit 40ish in Linx under load. I know it isn't correct but best I could do to estimate the temps.

[Osterman]

People! I could achieve 4ghz 471x8.5 with 1.37500vcore (bios) 1.344 cpuz, and lowering!
But I would like to know what you thing about LOAD LINE CALIBRATION (LLC), because I got it Enabled.
Later I will show you my settings.

And... OC NUB thanks for your help, there was others users who helped me, thanks!
The problem was on the COMMAND RATE, it was auto = 0 in my settings, so trying to do something else I have changed it for 1 and just like magic It got stable.

i keep LLC enabled too.

I use LLC also

If you have any questions, please be my guest to ask, also if you have any suggestion

[OC Nub]

If it is working don't fix it, but normally the MCH reference should be 1 or 2 notches up from the cpu reference. With 1.20v CPU termination I set the CPU reference to .760 or .785 and the MCH reference to .800 then raise the CPU termination as needed.

[Osterman]

So I should put CPU REF on .760 or .785 and MCH REF on .800, and then reise vtt without thouching those REF settings??
And always keeping mch ref 1 or 2 notches over cpu ref..
??
