I agree with you.pity because it was appeared to be rock solid,was gaming for 3 hours without any problems 4.2@ vcore 1.28, maybe i will put a few more volts through it.take care budQuote:

Seem to have figured out the hi temps on this thing. After reapplying thermal paste half a dozen times or so and trying different brands/types I turned the 120 facing up towards the top and temps went down considerably, also they evened back out within 1c to 2c of each other. I quess it wasnt making even contact. To test it I tried 4.5ghz at 1.45v and reached 72c max before failing Prime one core. A step in the right direction anyway.Quote:

[QUOTE=calpolyarc;3722882]Thanks mreld3r... very helpful. I entered the values you suggested... first thing, when I entered 1.34 for VTT and MCH Core the CPU and MCH References automatically changed to .848.... Is that ok or was I supposed to try and keep them at .76?
I was able to get into windows just fine up to 450x9 and run my typical software without any noticeable problems. I ran into problems though with memtest and prime blends (they failed immediately)... prime small fft's ran fine on a short 10 minute test but my temps during that were: 70/66/58/58 and the cpu read 71. This is too high correct?
Due to the memtest and prime blends errors I assume the RAM settings need to be tweaked?
you may wanna ask Jor or someone else for help getting a lotta ram stable, I only use 2 gigs here. And its not hard to get 2 gigs stable. I just wanted to help you get started. There a lotta very smart people in this thread that can help you a lot better than me. As far as the temps are concerned; Im not much help there either. I dont worry about temps. As long as it doesn't shut down on me, im happy. Especially during small fft's and IBT. I gotta old-timey cooler.
Oh yea, the refs are supposed to change with the Vtt. You may need to adjust the mch/ref to help pass prime-blend and memtest and maybe some more mch core?
So I guess there is something wrong with your OS, have you tried another installation CD?! Maybe Windows & Beta for free just to double check.Quote:

Thanks mreld3r for your help getting me started and your honesty.
would Jor or anybody else mind helping me get my 8 Gb's of RAM stable? My current settings and most recent questions/concerns are up above in post #2788.
Here are my specs:
Q9650 in EP45-UD3P w/ Xigmatek HDT-S1823 HSF
4 x 2 Gb Gskill DDR2 800 / 5-5-5-15 / 1.8-1.9v
Quadro FX 1500 GPU
Corsair TX750W PSU
Thanks!
try changing the vdimm to 2.0V and the MCH/DRAM ref to 1.00V if more vdimm doesnt help u could try losening the timings 5-6-6-18 maybe, or try a little more MCH core and see if that helps, when i have four sticks in it takes me more vdimm and MCH coreQuote:

Do more people have problems with the latest bios F7 for the EP45 UD3R?
Cause everytime when i flash to that version and load optimized defaults and after that customize settings in bios everything is fine, but whenever i turn off my pc and turn it on again (cold boot) it goes into a reboot loop 2 or 3 times and then it says checksum error and puts the original bios back (thank g(od)igabyte for dual bios).
Any ideas?
I have UD3R with bios F7, and works well for me.Quote:

Hmm which revision? I got 1.0
Same here.
No go. :confused:Quote:

As Cyfer stated, no problems for me either....I just installed another 4GB of RAM last night in a Revision 1.0 UD3R MB with the F7 bios and an 8500 chip. I've tried most of bios versions out there and none have caused me any big issues (but some have worked better than others of course), but F7 seems to be pretty stable for my setup. I'm currently running at 4.16Ghz (8 x 520).Quote:

The ram doesn't seem to be an issue. In windows I pass testing. The problem is the system simply won't reboot or shutdown properly, never mind S3 working properly. Is it a lack of voltage somewhere?Code:MB Intelligent Tweaker(M.I.T.)

Right now I'm at my power saving settings, default clocks + power saving bios options, and it reboots and S3's properly.
maybe that's working with 2 x 1gb sticks but not with my 2x 2gb ocz hpc reaper 1066 and e8400e0, using 445 cpu fsb and 1068 mhz on ram, my pc posts on the 333 latch 2.4b untill 1.26v mch which is not enough to be stable . When i go above 1.26v the computer just loops.Quote:

Anyone got 580FSB prime stable on the UD3P ? (not talking about pi runs or cpu-z screenies) I'm currently on F4 bios but having a hard time to stabilise it in Memtest test 7. After a few passes it starts to give some errors...
Might be the limit of this board. Maybe a newer bios warrants higher clocks...
This is my rock solid setup; primed, has encoded, and done a bunch of other stuff for about a week now almost always at 100% load. Not a single crash yet. I won't say fine tuning is done yet, as I frankly haven't found the time to adjust all settings to the lowest levels possible without compromising on stability; my obsession. :rolleyes: Maybe this helps those struggling with 8GBs, I don't think this board has a single problem handling that.
I'll do some quick synthetic benches, hopefully later today.

Can anyone confirm if ether F9a or F9b on the UD3P fixes the S3 bug?
I had to RMA my board because I couldn´t run bus 333, 400 or 450 and ram 2x1, 2x2 or 4x2 in dual channel at 1066 or 1080 no matter what, singel channel just fine or any 1:1 in dual channel.
They couldn´t fix it so I got a new board, rev 1.0.
Just about to set it up for some short test. :D
ghostleader,hope this one works perfect for you.good luck
Not sure about the S3 bug, but after loading the 9b bios (from v.8)i was able to get 1:1 with patriot pc2-6400 (4-4-4-12) ram and q6600 at 400 FSB and mostly stock voltages--something i was unable to attain before despite a lot of effort and tweaks with timings and voltages.Quote:

I'm pretty sure i didn't make any OS reconfigurations that would have caused the drop.
hmm seeing this , i've tested my board on deafult settings, and with cpu running @ fsb 333 and memory @1066 no problems, I only hope that a new bios will solve this board problem with 2 x 2gb ram and the 333 strap, and will allow better performance level on the 400 one (ofcourse for 2 x 2gb ) .Quote:
