Something tells me its the board because when i set the NB to 2.8Ghz and try to boot it my fan on my 5870 turns on 100% and stays at 100% at a blank screen no post but when i do a 2.6ghz bootup my fan on my 5870 turns on to 100% for about 2 or seconds then slows down. Makes me feel like the board is hanging...ive tried 1.77 and 1.6 bios.

It booted and ran for 45min in prime95 no errors CPU-NB@1.45v and NB@auto ive tried CPU-NB@1.5v and NB upto 1.3v...i hate computers lol

My NB is stock and it does the same thing on my 5770. Dont worry about it, i think its normal. Did it as soon as i put my card in. Its just annoying cause it sounds like a freaking turbine winding up.

good call! was thinking about something else at the time.

The thing about the link I posted is, There are two was to "burn" in your cpu one I posted a link to and the other is where you run your CPU at a unstable setting with a lot of voltage and literally burn the speed in by forcing it to run at those speeds @ 100% for a long time. This is supposed to work but the trade off is the the CPU life is greatly decreased and so is the life of the OC. I believe the link you quoted is talking about the second way of "burning" in.

hi , ive posted a couple of times but no responce, come on guys and girls help a fellow gd70 owner out, im literally pulling my hair out here, i have read this thread from start to finish but every tip or setting stated in this thread has not worked for me, the problem im having is that i can get it 100% stable @ 3.7 with voltage @ 1.35 but if i try to get higher than this i blue screen and it doesnt matter how high/ low i set the voltages or adjust nb frequency, ram, ht it just wont have it, heres a little info on the hardware im using,
955 c2, 4gb corsair 1600mhz, 4870x2, the gpu and cpu or both watercooled and the board has 5 120mm fans blowing across it from the rads ,so heat is not a problem,
im running windows 7 ultimate 64 and have flashed to bios 1.6.
any help would be much appreciated.

Hi, ezgonzo, welcome...

It would very helpful to all of us if you could put in your system specs in your sig.

As to your issues, I can tell you the IMC (integrated memory controller) of these chips is limiting. The rated speeds for these chips is 1333Mhz on the memory, anything more is considered overclocking the memory, regardless of what the memory is rated for (1333Mhz, 1600Mhz, 1866Mhz, etc...).

Try lowering your memory clocks to 1066 and reasonable (loose) timings (you're not expected to keep it there forever), and then retry your clocking, when you have the speeds you want, write down your settings (these will be for reference later on).
Then back your CPU and NB down to stock speeds and start working ONLY the ram up a little at a time. Find what it needs to run at rated speeds (1600Mhz & the rated timings), you will likely have to add volts to the ram (I run about .1-.15 extra volts to get stability with memory clocks over 1333Mhz).

Once you have the memory stable at it's speeds, then start adding a little NB only, get it stable, work it up, and then move on to adding in your CPU clock. It's a bit time consuming, but it is the best way to get stability.

And, try to avoid jumping around with different clock tests, these chipsets don't seem to like that very much. It seems we are all having some issues with this, of one kind or another.

So, lower the ram, clock the NB and CPU, lower them to stock, clock the ram, add in the NB then add in the CPU, and leave it and play your games and do your stuff!

Good luck, and make sure you add your system specs into your profile, it helps us significantly. Who knows, maybe I just gave you all the wrong info! <-- j/k, of course!

Mastiffman,

You asked me the other day about my NB and mobo temps. Well last night I mounted a 120mm fan so the center of it is right in line with my top GPU. I angled it slightly at the board and my result is pretty good. Dropped my motherboard temp down to 34C and my NB temp down to 50C in crossfire. The NB used to idle @ 54C in crossfire and load @ almost 59C. Now it loads @ 51/52C. I can post a pick of it later when the wife gets back with teh camera.

Ok so after more testing i have to believe its the bios that is stopping me from booting past 2650 on the CPU-NB. I decided to give AMD overdrive a try and i changed the CPU-NB multiplier to 14 which would give me 2.8. I did it prompted me to reboot and it did without a hitch I ran Prime95 an a lil after an hour i went downstairs i came back up and the monitor was at the bios stating press F1 to enter bios. So this has lead me to believe that the bios itself is actually holding my CPU-NB back. Im gonna try again and up my CPU-NB voltage because i was only running 1.3v for 2.8Ghz CPU-NB.

Im so clueless now i tried to repeat the process and it didnt work...then i was like "hey one more time" and it worked...so i have no clue what this means.

Having the same issues myself. Hope we can figure out what it is, driving me nuts, too.

Ive tried it 6 more times and it keeps working by booting into windows then opening overdrive and changing the NB Multi to 14x, hit apply and then it says it needs to reboot i press cancel wait like 30 seconds and hit the restart button in windows. Everything is good after that POST flies by, windows 7 boots up fine and everything is stable but if i restart my computer after having 2.8 CPU-NB it wont even boot to post. The board just stays at FF on the motherboard LED which means its trying to Power on and initialize the CPU but instead it keeps resetting over and over never booting to post.

So in conclusion i think its the bios that needs to be updated better to initialize the CPU at higher CPU-NB voltages.
