Am I mad for considering this?

Yep though that's probably just marketing :p

Update on motherboard, saying it was tested before sending and that it sounds like a short?? Would have thought a short would just stop the system from showing any life signs.

They have no clue :( It could have been many things and if it was a short, it was/is something shorting on the board.
 
Tbh I've worked on quite a bit of military electronics iirc all parts are of the shelf standardized parts, nothing special.

Atex rated parts is where the quality is at ;)

I'll run the board on a sheet of card tonight and see what happens.

If I can get the same debug code with the known working 8500gt out of the case then the board's 100% screwed.
 
Had whine in my lightning, very slight and only when I maxed everything out. Tbh I quite like the sound, gives me assurance that it's working hard :D

Board was through rainforest marketplace, so I have to return to seller, the guy seems sound enough I think he just wants me to check every possibility before returning it.
 
Just getting ready for a final test of the motherboard, thankfully all I have to change out is the CPU, though I'm really really fed up with the smell of TIM. Not to mention that Akasa TIM Clean is terrible, will be ordering more articlean (that I've been using for near 10 years now) once its back in stock.

New 7970 will be here tomorrow (provided DPD don't loose my parcel for a day like my order last week). I'll resist putting a waterblock on it until my lightning is sorted and returned.

No idea mate, all i know is this...

That's a reference, but slightly revised. There's actually a 2nd reference pcb that AIB's can use and that one is typically used with different caps. That MSI pictured is the same as the Powercolor. The problem with this pcb is that there is a capacitor that sits higher than the true reference pcb, so it caused clearance issues with early EK waterblocks. EK has since adjusted their blocks to compensate for the issue so it's moot now. Other than that, they're basically the same as there's no real discernible difference performance wise.

Cool, I just remember some oc editions had an extra vrm that was intentionally missing from reference cards. The extra vrm doesn't make any odds for waterblocks. I'll find a pic tonight to show what I mean :D

I think he higher caps was down to xfx...

Matt, this is what I meant by having 'all' the VRM banks full

Edit: From what I can tell the MSI 7970/OC is a VRM short like standard ref cards.
 
PGI, any old aftershave or nail polish remover is fine for cleaning TIM, anything alcohol based is OK. I wouldn't even bother applying more if you are just booting for testing anyway.
 
Yeah, I just thought i'd try the Akasa stuff, its a complete nightmare to apply, it literally just tips out of the bottle, unlike articlean that you can drip on to the chip and let it work its magic :D

I've used vodka before and had no problems.

Normally i use nail polish remover.

Yeah, what of it?
 
Its all good, the Lightning has 16 or so VRM's while the Matrix has over 20.

I've seen ref cards clock higher then my lightning did so its all lotto...
