Binning CPUs

[cleric_warlock]

After finishing my first PC build I got to thinking about things to do in a few years to optimize things better when it's time for a major upgrade or just an entirely new build. ASUS motherboards have the handy SP scoring feature that seems to do a pretty good job of quickly evaluating the quality of your specific processor as far as V/F performance goes - would it be a bad idea to buy 3-10 of the same cpu over Amazon/Newegg, put each one in the PC to get an SP score and then return/resell all but the best scoring CPU? If returning all the non optimal CPUs for a full refund was possible it seems like that would be the best option since in the end, you'd be sure of only really spending money on 1 cpu after everything is settled. What are the risks that such a big return would be denied? If I were committed to binning like this, should I return and risk denial or resell and do my best to avoid a loss and perhaps use the SP info as an extra selling point?

The SP info of a processor does not seem to be a reliable metric, there has been cases where simply reseating the CPU can change it substantially.

 

Unethical to return it, at best. Not a lot of benefit to be had either way, unless you're planning on XOC.

I don't know about NewEgg, but I recall if you return/refund too many high value items to Amazon, you account gets flagged.

You are better / safer to buy a bunch, MANUALLY bin them, and then sell off the other ones privately.

 

You are doing what Silicon Lottery was doing...in a way. They closed down, though.

But like what @svmlegacymentioned, SP info is not 100% accurate.

You would still want to manually OC it to see how is ACTUALLY does, V/F wise.

Makes sense, though in my case re-seating my cpu doesn't have any effect on the score. Seems like if I really want to split hairs and XOC the way to go would be with some form of exotic cooling. The idea of having to resell so many CPUs makes me nervous just thinking about it.

That would be really interesting to try after getting more experience in overclocking.

Keep in mind that a "golden" XOC chip doesn't always perform best under ambient temps anyways... It really isn't a linear scale of best to worst, so the SP score is unlikely to get you a "golden" chip for your specific use case anyways.

Not something an average user should care about since cpu oc is dead anyways, you arent gonna magically hit 5.5g allcore on a golden sample either you still need the cooling and a really good sample

 

 

If you want more performance just oc the ram or gpu

 

ram is extremely painful because theres tons of timings to play with and when 1 thing is set incorrectly the thing just crashes, 5-7% bump is possible though youd need dual rank config either 4x8 or dual sided 2x16 and not a light oc either maybe something along the lines of 4000-4200 cl16/17 but very tight trfc, sr dr dd r/w/act/pre, trrd, and tfaw (cl dont make a diff in performance so it can be sacked for subtimings that do make a performance diff) which is possible on an ic like micron rev e, theres also bdie but eh performance gains are gonna be miniscule vs cost (crucial micron bare pcb with 8gbit rev e c9bjz or rev j d9wsm go <20$, but bdie costs twice that amount), unless you wanna really dive into this i reccomend just staying away because ram oc is pain (my 1520 ddr2 took a couple days to get stable cause it crashes like 8+ hours into prime95 kind of painful)

 

Gpu oc is prob the most noticable and most painless oc, literally just playing with sliders, just use msi afterburner, crank power limits to max and raise core and memory in 50 and 100mhz increments with a stress/benchmark like furmark in the background and once you get artifacts just dial down till you dont and lower by 20mhz core and 50mhz memory as headroom. Ridicolously easy, risk free (gpus have no volt control, they cant corrupt os like you sometimes can with ram oc forgot to mention that), and very noticable performance gains

Not entirely... You can still tune for higher ST and MT boost. Out of the box performance is not: optimal.  AMD gives you +200MHz, some guys can get it, some guys can't.

Mostly

 

Eh its more like power efficiency not optimal, easy 20-50w power save by just undervolting, particularly on intel where idiot boards overvolt the crap out of the cpu, also just maybe detuning the cpu by 100-200mhz to run 1.2v or lower vs 1.3v for optimal v/f and power efficiency

 

Max performance is just dumb, you prob will only get a meager 500mhz going from 1.2 -> 1.5v (5ghz -> 5.5ghz) and thats assuming you got the cooling, maybe with a beefy ghetto loop you could manage but youd prob also need direct die waterblock

I don’t run Intel right now. But my 5900X boosts to 5150 no problem.
