Gigabyte GA-880GA-UD3H does this board support Vishera CPU?

[mmeyerssr]

According to Gigabytes specs listed for this board it says this board will run these cpu's with Rev 3.1 and the latest bios update. I'm wanting to upgrade and overclock. I've been told by others that it may be able to run it, but the 880 chipset will not allow overclocking. Something about not being able to disable APM? I've not yet looked but it would seem to me that this can be done on most any board and what does it have to do with oc'n the cpu? I don't want to run into problems after I purchase a cpu that I may not be able to return. I must be certain.

well.. it's a 4+1 phase board... which means it wouldn't be a great overclocker... just not robust enough.

Something like the Asus M5A97 R2.0, would be a bit more robust...

What does 4+1 mean? The Asus looks good for a good price. If I get both cpu and board I'll likely have to compromise on CPU a bit to get the cost down. Trying to stay around $250. Memory I have ain't the greatest but it'll do until I can upgrade it. I haven't done my sig yet but right now I'm running an Phenom IIx4 965BE@4.2Ghz. I'm using an H50 h2o cooler and if the room gets warm it won't manage that high of OC and I have to turn it down typically 4.0 My first choice was an Phenom IIx6 but the price is high compared to vishera. 1100T are impossible to find at least in the US and they'd be even higher than the 1095T which are about $270. I can get a used one for less but I'm REALLY skeptical about buying a used cpu. I have no Idea what the other guy did to it.

get a fx8320. its just an underclocked 8350, and will overclock up to those levels and performance.

4+1 is the phase power design of the motherboard. 4+1 means you have 4 mosfets designated to the cpu power regulation and 1 for ram and hypertransport. Generally in AMD motherboards you'll see 4+1 phase setups advised for 95W tdp motherboards at the most. it's really not very robust, and rarely has any sort of heatsink design for the mosfets (its basically useful for stock use, cheap, for business use)

4+2 would mean there is 4 for the cpu, 1 for the ram and 1 for the hyper transport. This is good enough for most overclocking IF there is a heatsink on the mosfets and you have good case airflow.

8+1 would be the same as 4+1 (for the most part, as overclocking will probably be hard or inadvisable on an amd system, unless those mosfets have heatsinks, and even then it probably won't be great)... only the ammount of power you can shove through the cpu will be greatly increased (meaning you can use a 125W tdp cpu)... of course anyone who's overclocked amd will know, the cpu is only half the story, and the lack of a robust power management for the hypertransport/northbridge will likely torpedo any serious overclocks.

8+2 would be ideal for overclocking a 125W TDP AMD cpu, for all the reasons a 4+2 setup would be good enough to overclock a 95W tdp amd cpu. Generally they just don't build these motherboards without heatsinks on the mosfets.

The answer to the question about support for Vishera CPU's, the answer is no. There are five PCB (Printed Circuit Board) revisions of the GA-880GA-UD3H. Only the last revision 3.1 has BETA support for some Bulldozer CPU models. Overclocking support may be absent, but people who wanted to run the AM3+ Bulldozer could when it was originally released in October 2011.

why would you recommend a cpu that is not supported ?

I found this board http://www.newegg.com/Product/Product.aspx?Item=N82E16813128519
It is 8+2 phase, has heat sink on mosfets decent chipset memory support is lacking a bit but for the price I'll live with it.

I wasn't recommending the fx8320 for the 880 mb. I was recommending it for the Asus M5A97 R2.0, in response to the op's comment that he'd have to go with a different cpu if he got the Asus motherboard (because of budget).. that said ~ i'm not 100% certain the m5a97 R2.0 has a 4+2 or a 8+2 mosfet system. I do know it's rated for a 140W cpu, so chances are, unless it has godly heatsinks on the mosfets its a 8+2 mb.

This board is extremely overclackable, I'm running fx4300 @4.5 and patriot 1866 stable as a rock. Not only is it overclockable but once the bios is updated to fgj you'll see the additional setting for the RAM once the Vishera is installed sing the mem controller is on the CPU. With CCC you can get this system up to almost 5 ghz. I'm not using mosfet sinks but have a CM scout case with all fans installed. Also using water cooler for cpu.
