Hi!

 I like the motherboard "MSI 890FXA-GD70" but, I would like to upgrade my MOBOs to support new FX AMD series...

 But, which new MOBO (with support for FX CPU  (APU now?)) have the SAME PCI-e slot layout than 890FXA-GD70 ?

Cheers!

You don't need to upgrade you'r MOBOs.
MSI 890FXA-GD70 already support FX CPU with AM3+ socket.
You just need to update BIOS to 1.9 or higher.

I did this just recently actually.

No, it does not work. It is a beta support (or something like that). I don't want it, simple because I can't use it!  :-/

I try it with FX6100 and it does not work... Even if it say so, it doesn't.

Also, take a look here (my post): http://www.tomshardware.com/forum/314264-30-890fxa-gd70-bios-update-blinking

I would like to upgrade the combo MOBO+CPU only...

Thanks!

Which CPU precisely?

Some say dont use tools and flash under windows, but i never had any probs with that procedure. I always do Bios-Ups under windows, never ever had any trouble with it.
One time i do a Bios Up under Dos procedure with a Asus Board and nVidia Chipset, reboot and dead. -_-

But i wont buy a FX, ( i bought a FX6200, laying here for a week and send back ), for mining, gaming there is no improvment to a Phenom.
Maybe i try a Piledriver if he can run on 890 Chipset.

It is becoming hard to find Phenom X6 / Athlon X4 in Brazil...  :-/

One more thing to import... Damn!

Also, I don't use Windows... I use only Linux and the BIOS upgrade was done with a 2G FLASH-DRIVE (vfat formated) using BIOS MZ-Flash utility...

Thanks anyway!

These boards lack the extra power connect on the motherboard that the 990FX series offers...... Have seen some funky things with overclocked FX chips on 890FX chipsets :)

I read the same thing over the Net...

And now we back to my question...

Which new MOBO have the same PCI-e layout of 890FXA-GD70?

Cheers!

Just find this post!

It can be used the way I use MSI... But for Intel CPU... Damn...

You can use the board.. I have a few of them.... Don't overclock much.... It's a decent CPU for the price.... I would wait for the Pyledriver cpu's to be released.. They will fit in this board....

It might be an AM3+, but AMD said you need a 9xx series board to use a Bulldozer CPU. I use the Gigabyte 990FXA-UD5, and it's great! It does support Bulldozer, as well.

It does... I have (3) of those boards with FX-8100's in them, working fine.. Upgrade to the latest bios, and off you run.

I'll do it!!

On all the boxes of my 3 890FXA-GD70's theres stickers stating 8 core cpu support..... am3+........



It works... and it will support the future Pyledriver....

If you are using more than 3 cards I would be really intrigued to know how you make it work!

See this post:- https://bitcointalk.org/index.php?topic=37880.60

I only ever used 3 cards, plugged directly into the MB, like you had. Sorry.

Only thing I can tell you is these Gigabyte boards respond positively to disabling unneeded stuff in the BIOS. Try disabling the 2nd sata controller, audio chip, the USB3.0 controller, USB2.0 (if you can), LAN (if you can), limiting it to 1 core, etc. Some people have had good luck with doing that.

I can run 5 cards no problem on this board..... 4 cards without an PCI-E extender...

On which board, the MSI, or the gigabyte?

I run 6 cards on my MSI 890FXA-GD70

MSI GD70.....

If you are just using it for mining then there's no point in throwing a Bulldozer in that board. Regardless it should work and I've got 5 cards running in a pair of these boards. Been working error free for about 2 months.

I use the Athlon x2 250 cpu for the rigs.. They work great... @ home 1090T for now.. until I see some decent spec's on the new Bulldozer style architecture...

I would recommend the GIGABYTE GA-990FXA-UD3 for your purposes, it has the same layout for pci-e except one of the 16x slots is replaced with a 1x slot, obviously shouldn't be a problem if you are running 6 cards since you are definitely using some extenders already.  It is $30 cheaper than the UD5 and I like the pci-e layout better.  It also has support for the FX processors.

Are you actually personally currently running 6 cards on a GIGABYTE GA-990FXA-UD3  ??

How are you doing that? I'm using an x2 250 and it maxes 100% cpu with only 3 cards. With 4 cards the rates go down considerably from what they should be. That cpu can barely support 3 cards, and definitely not 4. I'm upgrading to an FX-8120.

Why is your CPU being used at all ?



using cgminer there is very little, to no cpu usage.....

What driver/SDK? Unless you're over I:9, CGMiner usus almost no CPU?

besides mining bitcoin using amd cheapo cpu on gd70 board.. i am done investing money in amd
compat motherboards. intel all the way.

and i was a long time amd cpu user. bought my first intel this year when i ran amd for what seems like the
last decade.

I found the issue, was a bug in my miner. Moved to an older version, problem went away. Doh.

All of the latest miners use 100% cpu, seems like some sort of bug in the engine or mining code. If I swap to slightly older versions the usage drops to < 2%. Any idea what might be going on there? I'm running the latest drivers as of today.

For aggression/intensity, I"m using 14 under BFGMiner, and 12 aggression on phoenix.

I think the newer drivers introduced the 100% cpu bug, but only at high aggression/intensity. For me (driver 12.8), I:9 is good, but I:10 or higher isn't.

set affinity for all miner processes to 1 cpu core.
then save other core(s) to run the OS and feed the gpus

intensity depends on if the GPU is being used.... I have a few cards in my @home rig and the Desktop card uses I:6 and the others use I:9...
