Questions before I buy.

post #1 of 8
Thread Starter 
Evening, I was curious if anyone would like to put my mind at ease by answering a few of my questions about Silicon Lottery.

I was only a few days away (today) from buying a CPU and a graphics card to put the finishing touches on my build. I recently came across more funding for the build so I was thinking of getting the i7 6700K. During price comparison and looking at vendors and where the prices were I saw a forum post from 2013 talking about Silicon Lottery with a link to the website. To my surprise it was still up and offering guaranteed overclocks with certain voltages. Looking at that meaning behind Silicon Lottery I got an understanding about what the website was about but wasn't entirely sure how legitimate it was.

So after posting on Reddit and asking others about the website I found myself here on this forum. And now I would like to ask how reliable is it to buy from this website? The post-purchase testimonials are great to read but because of a few factors I'm a bit worried about spending the 400$ on the CPU. Mainly because of Dlidding. Is its only purpose to decrease the temps? What other things are done to the CPU besides just removing it and sealing it back on? Also If it voids 2 or 3 year warranty(which ever it comes with) would I just be better off getting one from say Newegg or would I be still be playing 'Silicon Lottery' with my money there too but also have a bigger possibility of a not getting a 4.7ghz overclock either way?? I do understand the website is for cherry picking CPU's and getting the best results, but can someone put my mind at ease on why I should go this route and not just buy it from another retailer?

I honestly just want to get the most for my money like any normal person would.

They are as reliable as can be, I've ordered several chips through them. Delidding primarily decreases temperatures, which can improve stability and overclocks, especially on Skylake which scales well the colder you get. They take the lid off, change the paste, then glue the lid back on. Delidding almost certainly voids your Intel warranty, but so does overclocking technically anyway.

No matter what you do, you're always playing the lottery. SL lets you know the chances of each bin on their site if you click on each processor. Right now they have fantastic prices, partly because Newegg and others are still price gouging. The best bang for your buck would be a delidded 4.7GHz.

I see. So even if I purchase from there I might not get the 4.7GHz? Or I just have a 50% chance based on the bin amount that they predict? For example on the 6600K page its around 70% or something. They will just give me one normally and hope it clocks at 4.7GHz? Or they will test it out to make sure it does as best it can then give it to me?

Because I do remember reading they will try to give the best reliable overclock at what you purchase it for. But its not 100% guaranteed.

No, they've tested it and it should run at 4.7GHz. In a way it is 100% guaranteed, because they allow you to return the chip within the first two weeks.

Okay last question. When they say they're binned at 50% if I pay for one at 4.7GHz and it doesn't go to 4.7GHz because its on the other side of the 50% am I still paying for that CPU and have to buy another? I know it sounds like a dumb question but if only 50% can get to a certain GHz what do they do with the other 50%? Is it just lost profits or is it really coming out of our pockets to get the clock speed we want? Someone in a post told me it was pretty expensive and I wasn't sure if the Delidding was expensive at 40-50 dollars(USD) or is it another reason such as this?

I apologize if its a dumb question, was speaking to someone about it a moment ago and they just happened to bring it up during our conversation.

They don't say they're "binned at 50%." They're just providing you some statistics to help you get a feel of how good that particular bin compares to the others.

The top 51% of 6700Ks they tested did 4.7GHz or better. You'd be buying one that passed the test at 4.7, but failed at 4.8. If you pay for a 4.7, you get one that does 4.7. If you pay for a 4.6, you get one that does 4.6 but not 4.7. If you pay for a 4.5 you get one that does 4.5 but not 4.6, etc.

The price of delidding is fair imo considering the risk of damage is all on Silicon Lottery. Skylake chips are very fragile.

I understand now. Thank you very much for your time.

here is my experience with the 4790K 4.8GHz. I skipped my SKL build since it was better to wait for Kaby Lake in my position.
