Gigabyte GA-EP45-UD3P....this a step up from Abit ip35-e ?

Been thinking of buying the newer Gigabyte GA-EP45-UD3P but but don't want to take a step backwards. Right now my Abit IP35-E is doing okay but its getting old and want a backup.
 
I stepped up from an Abit Ip35-e to the ud3p.
Voltages are much much more stable on the ud3p with the load line calibration enabled, which at the very least will allow you to set the cpu voltage for your overclock at only whats needed instead of more than needed to compensate for the V-droop on the Ip35-e.

The UD3P also runs cooler than the Abit ip35-e.

Now as far as performance goes, no difference i can tell going from p35 to p45. (unless you get a better overclock due to more stable voltages of course)

 
It's definitely a step up if your going to run a quad on this mb as the voltage are much more stable under load. You don't fear burning a fet or two heck even losing an entire phase when you oc as it is capable of doing so. Gigabyte really did a good job with this mb for it's price as they paid attention to fucntionality and stability as opposed to bling factor. The only quirk I found on this mb is that it goes into an endless boot cycle if the system crash or froze.

Generally, what you say about this model-line of boards is consistent with what I've heard. I ordered the GA-EP45-UD3R -- a version of the board with RAID 0/1/5/10 option. Some recent customer reviews are poo-pooing the board, citing a "quality-control" problem, but it's a very popular board, and very many 5-out-of-5-star ratings. I'm only getting it, because I need to rebuild a file-server to chuck a 6-year-old P4, Rambus-based mobo and RAID0 hard disks that have been running since January 2003 (24/7/365, too. Yikes!) I've got a spare E6600 and E8400 processor, hardly used, and some spare DDR2-800 RAM kits.

Some people who post customer-reviews don't know what they're doing, but I've had minor, peripheral problems (like a dead LAN component or bad PCI-E x1 slot) on less expensive Gigabyte boards, so "problematic QC" could exist among Gigabyte productions.

Bonzaiduck, You'll be happy with the UD3R, I can't wipe this stupid grin off my face 😀 . I finished setting my UD3P yesterday and let me tell you it's way better than the previous mb I had which is a T-Power I45. The Quad nearly took out an entire phase on that mb and I wasn't pushing it very hard. There are always QC problems with manufacturers. Like I said, it won't matter if we live 20-50yrs from now. It will still exist. Where there are humans, there are errors as nobody is perfect 😛. We just have to work with what we have and try to live with the quirks that are bundled with it (if there are any).

With a slight adjustment to cpu/mch reference/skew this baby is priming at 489fsb. Which the T-Power I45 could only dreamed off. The mb and cpu stays pretty cool also (could be the P45 A3 revision) also less voltage to the nb to stabilize 489fsb.

Regards,

 
I have just put a rig together with the 'P' model and other than getting a bad stick of ram, it's gone real well. Also using a E7400 cpu. Haven't tried anything in bios yet, let you know how that goes in a while.
 
I been reading on some other forums..Some having issues with two sticks of ram and not booting. Just my luck I will be using 2x2GB of Mushkin. If I can do 3.6ghz stable with my E8500 I be happy. I ordered the -EP45-UD3R should be in Wed of this week, I hope I do not have any booting issues.

With this mb, you can max you wolfie if you have a good cooler. Estimate 4Ghz-4.4Ghz, depends how well your chip scale with voltage. It'll be a peice of cake. If you manage to encounter the fruit loops issue (boot loops) revert to the first bios release. I played with all the new bios release on my UD3P and all of them from F5-F7 had that annoying issue. The first release bios fixes that which is the F4 bios. When you get your mb, replace the NB/SB tim with as5/ceramique/tx2 etc and save the pads somewhere for rma purposes. This will keep the NB cool. The mosfet sinks are just warm to touch even with a Q6600@3.6 (160w-170w load) hence your barely scrape that power usage with your wolfie.
 
On the UD3P, I had no issues with 2x2 GB of my Mushkin...was fine up to 485 FSB (didn't try higher).

But running 4x2 GB Mushkin it did not like.

Couldn't POST over 465 using 2.00D strap, & while it could using 2.00B, it was flakey, didn't always POST, & i could not get it stable.

Does the NB/SB run hot?

Just the NB iirc. Forgot to do a finger test on the sb lol The heat on the NB is nothing compared to my previous mb which is an i45 revision a2. That mb, you can cook eggs and bacon while priming 🙂
 
I got the UD3R installed all seems to be okay other than no HDD LED and front USB ports seem to have problem. My webcam will not run from the USB ports thats in my case but runs fine on the back USB ports. Flashi drive runs ok on the case USBs..odd

With the HDD Led, you might try re-seating the connection as I had trouble the first time with my UD3P. Take a glance at the manual. What psu are you using? If you have a dmm (digital multimeter) try measuring your 5v rail. Have you noticed this mb, that when you power down the machine. It doesn't quite turn off the mouse and keyboard (ps2=mouse/keyboard).
 
I'm using PC Power and Cooling 750w PSU, 5v shows as 5.02v ...I starting to think maybe the mobo is shorting against the case but thats just a wild guess.
 
It's probably a good idea to check the mb out of the case. Just test it ontop of the mb box (no foam/anti static bag).

That is with LLC (load line calibration=reduce vroop). IMHO, the mb has misaligned voltage for the cpu. Gigabyte sets their upper threshold for vcore max 2.3v but I doubt it though. More like 2.1v-2.2v. Above 1.40v settings, the compensation to get the desired vcore in windows gets larger (.030-.050). Without LLC, I have to set vcore close to 1.60v to get 1.44v loaded with prime hehehe.
 
Runnig fine at 3.6ghz, temps 29-30 idle..max out 48-51C Yeah if all else fails I guess I could get a USB Hub, that would make it better when using the webcam
thanks
 
What cpu are you running and the rated speed of your ram. I'm playing with a strap/ram divider I haven't used before and i'm quite surprised with the results on this mobo. This is under 200mhz/2.66c strap iirc. The lowest performance level/static t read control you can select using Cas5 ram is PL6 and you don't have to break 400fsb+ to get some bandwidth out of your ram. So if you are at 400fsb, the ram runs at 533mhz PL6. You just have to ensure the ram runs error free though at that speed while the whole entire process, you are aiding the ram oc with nb voltage. No gtl refs etc involved.

Try flashing to a new bios. perhaps you'll find that fixes your issue with usb. Great start so far with your UD3 🙂

Edit:

Here's the strap/divider i'm telling you about. With PC-8000-PC8500 ram you can boost your read speed and lower the latency in everest without breaking 400fsb. With the oc i'm at, I hit just above 9k in read and 55ns in latency. Which is good enough for day to day usage. The strap will default to Performance level 7, you can change it to 6 and bump NB voltage to mid 1.20v for the system to boot properly and just try to stabilize the ram oc via vdimm. You don't have to touch other settings except those 2 I mentioned. Which makes it a very easy process to gain some speed.

Weird problem you got bro. Check your case and see if the usb/pwr/rst/let were somehow pulled accidentally to the front of the case. The USB I got hook up via mb works. As I always used it to update my bios. Check the mb manual also. You might have just wired it improperly. You can't have that much bad luck with 2 units. Although reset switch on mine doesn't work. I'll just attach it to the clr cmos pins and use that switch to clear the bios. It's painful having to remove my hd's and graphic card just to such things.... 🙂
