** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[HousERaT]

Anyone care to share what are considered safe voltages for the CPU PLL, CPU Termination and MCH Core on a wolfdale? Air vs Cold? TIA.

[IanB]

Since there seems to be some confusion about what voltages the BIOS is actually supplying, are there confirmed voltage read points for these boards yet?

[gUzE]

is the F5a bios only for UD3P ou also UD3R???
I'll post some maximum fsb with q6600 later

I know this is a dumb question, but I'll ask anyway:

Does anyone know if Gigabyte plans on releasing a DDR3 version of a UD3 board?

Edit: LGA 775 P45 DDR3 version

On another note, ordered the ud3p, q9550 and 8 GB of G.skill RAM, due to arrive on Monday. Time to step up from my old 939 system.

Hep hey, just got a secondhand P45-UD3P 1.0 and I'm on the hunt for 4.5GHz on a E8400.

But there are a load of settings to fiddle with compared to my old Commando so a few tips are more than welcome.

I can boot into windows no problem at 4.5 and run a few minutes of Orthos before it gives me a "Rounding was 0.5, expected less than 0.4" error.

Settings:

500x9
LLC enabled
CPU VCore: 1.375
CPU Termi: 1.240
CPU PLL: 1570
CPU Ref: Normal

MCH Core: 1.320
MCH Ref: 0.7650
MCH/DRAM Ref: Normal
ICH I/O: Normal
ICH Core:Normal

DRAM Voltage: 2.1
DRAM Termi: Auto

2.00D, X.M.P Disabled, Performance Enhance std. and SPD Normal.

Any suggestions where to start (what to touch and what to leave be) to find some stability?

I was going to try and buy that board and slap some cpu's in it to gun it high, but after people were getting desperate on ebay and bidding over $200 for a new one, and then later, I saw a bid of over $200 for a ***USED*** one, and even saw one sell that had a couple of bent pins (I emailed the seller) for over $140, I was like....forget it.... can only trust XS sellers or new items if elsewhere...

[In-Fluence]

Makes me wonder why my USB3P would have gone for less than £50 about 6 months ago if I hadn't reserved it. $200 is a lot for an old gen board and I'm glad I kept hold of mine.

Anyone got any settings or hints for an e8x00 above 600fsb? I can do 1M PI runs but not 32M at 600x6 and 605fsb max. I've tried all combinations of cpu/nb skews which don't seem to make a huge difference. Refs have helped me get 1M stable even at low volts (1.34vtt and 1.38mch) but it always hangs or gives rounding errors around 10 secs of 32M even with v.high volts with various refs... Currently on F2d bios (not that there's a lot to choose from on the USB3P)...help!

[Falkentyne]

Getting above 600 FSB is more luck than anything else. The highest fsb I ever saw mentioned was like 613 FSB and that was on a ep45 ud3p. And board revisions mattered, too.

I guess you may have to subzero the NB and throw a lot of volts at it...

Wow! I just got a almost new UD3P 1.0 for $72 with all the accessory's and the box.

[Don_Dan]

@nullface: Play around with voltages a bit, you should be able to get it stable if it's already running Orthos for a few minutes. Just make sure your NB isn't overheating. And maybe raise MCH ref a bit, to 0.776V.

@In-Fluence: Did you try higher Vmch? Make sure your NB is cooled properly, 32M stresses it a lot more than 1M.
Which memory kit and divider are you using?

How'd you manage that?
If it was on ebay, can you link me to the item number?
I hardly trust people there; you never know when you are going to get a dead board, and then get hassled with "no refunds." But I guess things are better than they were eight years ago. The last mainboard I bought on ebay was advertised as a "working pull", but was COMPLETELY dead, not only were some of the caps bad, the chipset itself was dead. Luckily Homie over at the defunct motherboardrepair.com fixed everything...

If something like this had happened now, I would have filed a chargeback for fraud....

BUMP! Anyone playing with a DMM out there?

Just posted my review, check out the voltage regulation section. It should have everything you are looking for

Thanks for link... I agree with "bigslappy"... nice review.
