post #8411 of 9641
cpu-nb is NOT NB vcore, theres a definate setting for that, cpu-nb can go as high as 1.55, but I hear you dont want to go over what your cpu vcore is. Im 4ghz at 1.45vcore (rounded) and got my cpu-nb at 1.4, dont think I need it tho.

From what I understand CPU - NB voltage is the power for what drives the connection between the two, I think its on die (cpu).

Anyone know what errors '08' and '2A' stand for, bout to check manual or MSI site... Both of those are the error I STILL get first boot after sitting off all night. Two days in row all I need id to hit reset button,a nd boom, perfect, but I get either of those at boot, like they are both related to same thing, just minor difference. IDK, HELP!!!

I see all the time 1.55 is the max cpu vcore for 24/7 running.

My question is it safe to go higher for 24/7 running if my temps never past 49c?

Same with nb you say 1.4 is max but my temps at 1.4 never past 40c do i still have headroom?

load temps prime95 after 5 hours.
cpu=46c @1.6v nb=39c @1.38

1.55v is max for both, according to AMD, cpu vcore and cpu-nb. I just dropped my nb down to 1.35v according to Everest, and cpu-nb to 1.3, Im perfectly stable so far, about 40 min into OCCT Linpack test.

Im gonna look into what CPU PLL and PHY DDR voltages are. I figured out vref is 1/2 of DRAM voltage, according to the info when you hover over that option. 1.76 vDRAM equals .881 vref

Hey guys. First post in this forum;

I have an MSI 790-fx GD70 currently running a x4 965 with a Corsair H50. I'm looking to upgrade to a 1090T. Now, I've been reading about some people having issues with the x6 on the GD70 to the extent that kills the board. Can anyone shed some light on this? Has the issue been fixed, or were those people just the unlucky few?

With my 965BE I've had no issues at all. I've pushed upto 1.5V without any issues so far.
Also, worth noting is that I use the 140W version of the 965.

EDIT: I also updated BIOS about a week ago.

EDIT: I also updated BIOS about a week ago.

I just made the switch yesterday myself (from the 965BE to the 1090T) and no issues so far. Have been OC'ing and I am presently at 3.9Ghz/1.3V stable (5 hr. Prime21).

All I did was make sure I had the latest BIOS (1.G aka 1.16) installed, set all my BIOS setting to optimal (in the BIOS) and then made the switch.

I did have one small issue in that the 6 cores were not showing in my monitoring software but that was a Win 7 issue which I quickly resolved after Googling it up. Your CPU temps may also be off by some 10-12C. This means that what your monitors read (Core Temp, HW Monitor, AOD, etc.) will be some 10-12C lower than the real temp. Core Temp for example allows you to "offset" the CPU temp until AMD gets this fixed. Most seem to just add 10C to whatever they see as the CPU Temp.

Other than that, I have not read of anyone else having a problem of boards burning up or anything like that to be honest.

Thanks for the reply. Lets hope everything works well for me too. I'll just make sure I update my BIOS before switching them out.
It does make sense that if the board handled a 140W CPU, it shouldn't have problems with a 125W one.

However, I've read that because the 790FX employs a 4+1 phase switch (or something like that), it has problems. Dunno.

Just as a warning my 790FX GD70 died within 45mins of installing my 1075T

It starts with the motherboard whining under load, so if you install a hexacore and you get whining while stress testing stop the test and shut down your computer and let things cool down.
post #8420 of 9641
Mebbe people were using the phase controls instead of disabling them.

Here's my lastest stability test, looks good, only gonna do a 1.5 hour test cause that 100% load, and if it was gonna fail, it would have, lol.

nb never broke 34C, lol
