Can anyone confirm if these screws will work for using the stock KPE Back Plate?

I bought these at Lowes. The only thing I don't like is that they are flat head instead of phillips, so extra care will be needed I'm sure.




One more thing what kind of washers should I use with these, metal or plastic?

EDIT: I think I'm going to try to find these with phillips head instead. I found some on ebay. Only local hardware stores here in town are Lowes and Home Depot. No Ace HW : (

yeah those should work only way to no for sure is to try it out wink.gif

and i dont think you need washers unless the screw is a little long..... i bought m3-.50 x5 screws and they fit perfect
the m3-.50 x6 might need a washer and i think plastic would be better

also they dont need to be that tight so i think flat head will be just fine also

@heyguyslol For some reason I didn't see this thread and was posting in the Classified owners thread. redface.gif Regarding the screw issue with the stock backplate you can try this:

Had a blast installing the EK block on the new K|NGP|N and finding solutions to a couple problems.

First off, I wanted to use the stock backplate as it just looks great and should stay on the card. The problem is that the EK block uses a larger diameter screw, which in itself isn't a problem, but the diameter of the screw head is the issue. They won't fit in the recesses that the stock screws go in.

I took a handful to the garage with a stock size screw to use as a guide and mucked one up trying to grind down the head before coming up with an easy solution. Use the nut that came with the EK block as a stabilizer on one end held by a micro set of vice-grips and then turn and stabilize the screw while on the grinding wheel with a small screwdriver. They turned out way better than I had expected. The stock backplate pads are thinner than the plastic washers that come with the EK block so the screws are long enough if you turn the heads down. As a bonus, they sit flush!









The card is just massive... One thing I wanted to address was cooling the VRM power circuitry that the EK block doesn't cover. I am sure open air is probably fine, but a little extra cooling can't hurt here.

Somebody might recognize the heatsink as a ramsink from John Hillig ("Viper John") from a long time ago. Great guy and I always enjoyed talking with him. I have a couple sets from some old 8800 GTXs. He made some pretty nice pieces and I still find uses for these things. The ramsink fits almost perfectly over the MOSFETs. It is a little close to the chokes on one side so I cut and applied a strip of the rubber insulator that EVGA includes with the card. I let the ruber extend down past the sink to the board surface to make sure it was insulated. The small resistors on the other side, I think, are flush with the other components, but I let the thermal tape (3M) hang past a bit just in case.







Does anyone see any problem with the heatsink as installed? I believe it is not in contact with anything and the insulator strip should prevent any issues if this shifts or gets hit for some reason, but I'm open to suggestions.

I think it turned out pretty nice and I've really enjoyed getting back into this hobby. The reference Ti is coming out tomorrow and we'll see what this card can do over the weekend.

Got the KPE in and running! ASIC was higher than I expected:



Just started testing on stock bios at stock volts. Firestrike is clean at 1372 core at only 1.200v! biggrin.gif Temps are 35-37C. This is with a single DIP switch set for voltage.

Thinking I got a good one here. More volts and colder coolant to come.

I just found the following at the EVGA Forum about the lack of proper holes for the EKWB Classy backplate for the KPE's:
http://forums.evga.com/tm.aspx?m=2116917.

From Post #9:

"Dear customer,

Thank you for contacting EK Support.

We are sorry, but this backplate was not particularly design for KINGPIN videocards.
It is compatible, but it was designed using non KINGPIN videocards and before KINGPIN videocard was release.

If you need any further information, please do not hesitate to contact me.

Lep pozdrav, Kind regards, MFG!
Peter Šajn "

What bloody good is a "compatibility chart" that says there's been a "physical" compatibility check with the parts in which you're interested?
After all the hassle I'd have to go through to sell the one I bought, (PayPal, packing, shipping, tracking, some doofus whining there's a speck of dust on it and "I want my money back or I'll have your PayPal account closed", etc. etc.), that really makes selling it not very feasible.
I guess I'll just try removing the original backplate, mark where the holes are supposed to go on the EK plate, and try drilling them out and just use the EK backplate on the bottom card.
In the 1st post of the above thread, from the EVGA Forum, there's also a problem with an EK backplate riser hitting one of the cards power connectors, causing the card's pcb to bow &/or distort.
That means breaking out the Dremel to get rid of the useless riser.
That's a real physical compatibility check you performed there EKWB! rolleyes.gif
I think you qualify for the US Air Force as a QC&E inspector.
(Oh, Slovenian. Now I see. Getting back at us for Ronald Reagan and the fall of the Iron Curtain, huh? I thought that was a good thing?
That's okay, though. It won't be long before your Uncle Boris comes knocking on your door, too.
Just as he's doing in Crimea. With one of his huge T90 battle tanks.
Sweet dreams, Peter Šajn! And welcome back to the past, comrade. smile.gif)

Sorry, no. This is on the stock bios with the +25mv DIP switch set to stock (1 on 1 off) and voltage untouched in PX. Reads 1.187 normal and 1.200 loaded. I will break out the DMM tomorrow to see just where it's at (1.225?). This is replacing a locked reference Ti that would do 1411 at 1.212v (10C loaded temp) and 1372 at 1.212v (30-35C loaded temp).

Stock LN2 bios?

From the DMM you are probably in the 1.26-1.3 range at those clocks.

Just for clarification the modding you did to the back plate screws to get a flush look on the stock KPE back plate, is this a required mod or just a mod for better aesthetics?

And about the heatsink as a ramsink, let us know how it goes. If it works without any probs that may be something we can all consider.
