Im looking to spend a few hundred bucks on some equipment to mine verium. Im not expecting to get rich, but am not sure whether to buy old dual xeon server setups, or a small sbc cluster.

Does anyone have any experience mining verium with xeon e5645's? https://ark.intel.com/products/48768/Intel-Xeon-Processor-E5645-12M-Cache-2_40-GHz-5_86-GTs-Intel-QPI

Im trying to decide between something like 2 of those on a server motherboard, or an odroid mc-1 cluster.  The odroids sound like more fun to me, and a single cluster gets from 1500-1600 h/m as far as Im reading (about the same as my old 2600k).  But if I can get more hash from the xeons Id consider them..

WHat specs are important for mining verium?  Memory? the amount or just the speed?  

If anyone can point me to a verium specific forum/thread it would be greatly appreciated (other than the announcement thread here)

I have an old antminer s5 that loses half its hash every once in a while. When on btc.com, viabtc, or slushes it happens very rarely. But if I mine on suprnova, or blockfactory it almost instantly drops to around 600GH/s.  I have googled around and a lot of people have had one board drop out, but everywhere I read when they have it happen to them, one board totally loses power. That isnt the case with me. Both boards still have power, and im pretty sure ive have it happen with both boards at times which im hoping means my hash boards are fine. Maybe the "circuit board"?  That would be a great answer as Ive seen them pretty cheap.

Does anyone have any guesses as to why it would happen WAY more often on blockfactory, suprnova and zpool. And VERY rarely on viabtc, slush's and btc.com? And when it does happen on the big pools, it fixes itself within a couple minutes. At blockfactory ect, it will spike up to its normal hash for a minute or two, but drop back down like clockwork.

Any help would be appreciated.  In a way Id like the option to mine stuff like digibyte in hopes it will rise in price more than btc since im playing with very little hash, but right now im stuck with btc or bch unless I want to give up half my hash (i dont)

I picked up an old s5 a while back.  

Right now I have it set at 375,  getting 1.3-1.4 GH/s.  One chain seems to max out at about 57 degrees, and the other one about 10 degrees cooler (chain 1 is the hotter of the two). Is the difference in heat normal? Or should I maybe pull it apart and give it a good cleaning?

Right now I am running it with the stock fan, with the blue wire removed to disable PWN as I heard stories of them frying when they loose internet. Im assuming they fixed that via firmware, but I prefer the fan maxed anyway.  I also have one of these on order that will arrive tomoorw for the pull on a push/pull setup  Looks like it should work pretty well.   https://www.amazon.com/gp/product/B009OWRMZ6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

My question is when overclocking, is my main concern to watch the heat and hardware errors and if they are acceptable I can still crank it up?

EDIT: Im using a 980 watt server power supply model number  "DPS980CBA"
