Using Everest Ultimate for most temps. It says NB:51C with 1 GPU in, but I've been stress testing for the last 5 hours. It's usually 47C and 54C with 2 GPUs in.

Trying a different setup at the moment, 3600MHz (18x @ 1.48v), NB: 2400 (12x @ 1.26v), HT link 2000(10x), RAM: 1333 6-6-5-17-22-1t. I left my NB voltage to auto and it bumped it up to 1.29v.

Anyone having problems with bios 1.6 and NB not going beyond 2.4

My CPU-NB is at 1.25v and NB at 1.2v but my NB temps can go up to 70C when playing a game according to Everest. I have 4870 CF too. My ambient was 30C though that day though. I need a fan on it.

Edit: I strapped the stock AMD fan to the NB heatsink. I am now getting 10C cooler NB temps!

It's probably your CPU fan orientation. If you've got a push/pull configuration then there's nothing really being blown at the board. My Big Typhoon, especially with this fan, blows directly at the board, so all at the same time it cools the whole DrMos thing and my ram. Although when I mount my 2nd GPU I'm going to install an supplemental 120mm fan blowing directly at the chipset. I did this in my old CFX3200 and it worked great.

I just noticed your edit. Post some pics of how you strapped the fan to the heatsink. I'm curious.

no, I'm running the 1.6 OFF and I run my NB between 2600 and 3000. If it was giving issues I would try the 1.53b as I know I was able to get the same 2600-3000 range on the NB.

Mav - I had issues getting the NB over 2.6 before. Here is what did it for me:
In the bios the second voltage oprion, CPU-NB set to 1.3125 (and leave it there), and then use the fourth option, the CPU-NB offset to push your NB volts higher.

That was the only way I could push the NB higher, after doing it that way, I got to well over 2800, stable. Using just the first option I was not able to even get 2.6 stable, or anything over that to even boot!

Good luck, buddy, let me know if that helps!

Hey everyone! I am doing a system build with the MSI 790FX-GD70 in the next couple of days. I'll be signing up as soon as I get it built and OCed and what not.

3rdman

Well after saving money for the past few months, I've finally built my system...very happy! Quick questions...This is the first build I've done since 2002 and I put together an AMD 2800+ cpu paired with an ATI 9700 Pro so I'm a little rusty.

Anyways...Is the audio onboard the motherboard capable of encoding DD and passing it through the HDMI as 5.1 surround? Movies come through is 5.1 with no problem but games and apps are all stereo...Is it me and my drivers or should I be investing in a sound card?

BlackOmega

Marc, how and what do you use to test stability? And for how long?

And which Voltage settings for the NB are you specifically talking about?

I was able to get my NB to 2700 with 7-7-6-20-27 timings but it fails prime after 3-3.5 hours. Although it passes memtest for 5-7 hours.

Well, it seems the memory is the big hold-up with stability. I have been doing so many changes and re-installs and tests, that I honestly don't remember how I got it stable!

But, usually I will drop the CPU to stock speeds, and up the NB with RAM @ 1066 7-7-7-24 and test in Prime. If it passed over three hours I was ok with that, at least I knew I was usable for day to day, which is what is most important to me.

The memory is the hard part, these IMC's are hard to work with sometimes. Try upping the NB, testing, and then upping the memory, and testing again. When it's stable enough for you, drop the RAM back down and work the NB up again, testing for stability, etc.... Once I have the memory and NB worked to a good spot, then I'll bring the CPU back into it.

The 1st two volt options are the CPU and CPU-NB volts, and the second two are the 'offsets'. Whenever I go past the stock setting, I always leave the top two @ 1.425v and 1.3125v and then use the offset to raise above those levels. I found that if I only used the top two to raise voltages it wasn't working, especially with the NB.

Hope this helps, and remember, anything over 1333Mhz with the RAM is overclocking with these chips, their IMC is only rated for 1333Mhz, although many people have managed to get them as high as about 1780~Mhz or so.

Good Luck,
Marc
