Just picked up an e8400 EO. Going to try my luck with a dual core on this board. 1.2375 vid, not a good start lol. Have an old CO 8400 with a 1.125vid with 2 stuck sensors, but a good clocker.

mine is 1.2375 vid oo.and is an awesome cpu.whats your batch#? mine is Q843A771
mine will do 4123GHz with default vcore,1.237.:D lets hope you got a good one too:up:
Hey radaja, my batch # is Q843A900. Trying to figure out the reference voltages. priming at 4050 now.
Was wondering what percentage to use for MCH Ref. to vtt? Got a bsod a few minutes ago. Had the CPU REf set to normal and the MCH Ref set to .738 with VTT at 1.260v. Was trying 450x9. Maybe just bad settings but doesn't look like this is going to clock as well as yours.
mine likes 0.750 for vtt/1.28 or vtt1.20 mch ref 0.700.and cpu ref at 0.76 for vtt1.20
maybe try this

Going to try that now, Thanks. I do like the temps better than on my quad, hardly gets warm in orthos.
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.Quote:

Thanks for the help radaja :up:
no problem.good luck tweaking it.:)
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:Quote:

Nice!! Another great OC! and nice chip!:up:Quote:

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

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. :D 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:confused:.
And anyway I still don't know why I can't OC well with my Ud3P??
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.Quote:

What problems do you encounter?
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! LOLQuote:

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.
yes indeed,thats pretty damn good.:D
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.
