OK, I'll reconsider a UD7 at this point. It's going to cost about $40 more than the UD3, but I might rather pay the extra money for the piece of mind. I just don't know at this point. I guess the fact that Newegg.ca is currently discounting the UD7 from $215.99 down to $185.99, with a further $30 gift card to bring it down to $155.99 is a sign from god that I should just buy this right now and have done:smile.gif

That makes the UD7 significantly cheaper then the Sabertooth, all the way down into UD5 range. drool.gif

The cooling solution on my 790gx board is vastly better than the one the ud3 came with. Its all copper and heat piped. I suppose you could mod it to fit. I didn't spend the time to do so.

Thanks for saving me the trouble of investigating. I guess the price of copper is just too high nowadays to use it on sub-$200 motherboards. Well, Asus at least seems to just use more aluminum to compensate. I really don't know which board I'm going to end up with for my 8350 at this point. rolleyes.gif

Well, on closer inspection, it's $185.99 with a mail in rebate of $30. Depends how you feel about mail-in rebates. I'm familiar with the Gigabyte ones since I went through the process to get $20 MIR from my Gigabyte 7950 card. I ended up getting $18 because they charge you $2.00 to 'expedite' the rebate card (it's a single use AMEX card you can use anywhere that takes AMEX). If you don't pay the $2.00, it'll take weeks and weeks for you to get your rebate. As it happened, it took about 7 days with the fee. So you can consider the $30.00 MIR a $28.00 MIR. smile.gif

Prime defiantly isnt working properly with PD.
2 hours on max with IBT stable with max temps of 58C
10min stable on prime with max temp of 50C then 4 cores fail with illegal sum out.
Have to go right down to 4.2ghz to be prime stable no matter the voltage.

2 hours BF3 stable
Every other bench mark works perfectly fine.


But here is my final settings.

4.8ghz
2.5ghz nb
2.5ghz ht
2.02ghz ram
5.1ghz turbo

1.5V vcore (higher then I need for 4.8ghz but 1.5V is needed for turbo mode to work at 5.1ghz)
1.287V nb
2.69V VDDA/PLL
1.65V Ram

Exactly what happens to me at 4.7-4.9Ghz clocks, 1core would get illegal sum out error at 4.7ghz (core 7) and at 4.8 and 4.9 3cores would get them. but at 4.6 I am fine, already ran 24/7 of it at this clocks which i use as daily clocks for now, and at 5Ghz can run 2hrs w/o errors but temps is too high to run it at that clocks.

Not for me, at least. The fact that it's prime95 that's failing isn't the main point. As I see it, if any correctly written program fails to execute properly, then the system it's running on isn't stable. Any properly written set of instructions should produce the same result on each system. If solitaire was the program that was failing instead of prime95, I'd still be saying the system isn't stable.

That so many systems are failing seems to me to indicate that it's just being very very good at finding instabilities. Maybe better than most people would like or need. After all, how many people are going to be "playing" a tough game of prime95 and have their evening game play end on sour note because of a crash just when they got to this interesting part... Not going to happen.

just because it is correctly writen doesn't mean it ALWAYS works. I was part of my schools ROV team and we had custom written code for the robot. it worked perfectly fine for 3 weeks and then suddenly one night it wouldn't connect even though nothing had changed. sometimes things just don't work.

i don't think you can call your system "stable" by the use of just one program. i have ran prime till the lights went dark to have it crash opening chrome. i call my system stable after it has done a mix of everything i do on it be it games, heavy video encoding, web browsing, or benchmarks. if it passes all that... then its probably ok. but stability cannot be determined solely on one program.

i also think there is some kind of incompatibility with PD and prime. its not a coincidence that THIS many people are failing when they shouldn't be ie: stock settings

It' BECAUSE the heatpipe transfers heat away from the NB to the VRM heatsink that it runs cooler. That's the setup the UD5 uses, and your UD7 even connects the southbridge to the NB and VRM heatsinks for the same reason. The dumb idea was to keep the NB on the UD3 isolated. There's no way to conduct the heat building up anywhere else, except into the air, which is a very poor conductor of heat, as we all know. Maybe I should take the heat sinks/pipe off of my old UDP4 board and retrofit it onto the UD3...smile.gif

Hey thats cool, I just made a few suggestions to keep it cooler for the other guy. I just reviewed a Sapphire pure black 990FX for example, and I know for a fact that the heat pipe connecting the VRM to NB was warming up the NB that idles @ 60c . My point was replace the cheap TIM, and they are designed to tolerate fairly high temps. I have no idea why he took offense to it. I use a fan on my own NB . Can't makle everyone happy I guess biggrin.gif

Does anyone have any ideas on why I'm stuck at such a low NB and HT speed? I see everyone else running 2400+ but I can't run that without it becoming unstable in OCCT. More CPU/NB or NB volts? Am I missing out on much performance?

I'm another one struggling for stability in Prime. OCCT stable though, and lots of video encoding, so I'm pretty happy. I still have this slight doubt in my head though.

i find that if it passes video encoding like AVS or something along the same lines, i won't have any issues.

what are your voltages?
