Binning Haswell CPUs for memory OC

[sabishiihito]

Does anyone have a quick and dirty method for binning Haswell IMC on PSC/BBSE 2600C8+?

[Splave]

try them on out is all you can do low SA VID I heard, but I dont believe it

[TaPaKaH]

lowest SA for PSC at 1333 8-12-8 generally works, if you have a set of PSC that can do it, that is

[sabishiihito]

It's just infuriating trying to figure out if the sticks can't do the timings/speed, or CPU IMC can't handle it, especially with all the voltages you have to tweak (VCCSA, VCCIOA, VCCIOD, VDIMM, VCORE, VRING, VRIN)!!

[TaPaKaH]

SA depends on CPU (seen many refresh chips run PSC with 0.8-1.0V, pre-refresh might need 1.2+), IOA/IOD at 1.10/1.15 is sufficient but can also work lower, Vcore/Input/Vring only matter for Core/Cache freqs, Vmem depends on kit

I usually leave auto SA when I try to overclock PSC, but recently I have found one 4670K that refused overclocking my PSC to 2600MHz but with Samsung that chip worked at 2800MHz

I have on for sale that can do what you wish, pm me if interested.

I still can't push BBSE to 2666 but at least I managed a 2600C8 tWCL6 run with CPU and cache at 40x.

On asrock z87 matx and atx form factor should work at 2666 tight with +0.01 Sa ,+0.01 Ioa and +0.02 Iod. Sometimes when you push for more frequency on cpu SA needs to be lifted as well.

Where i can see stock voltages values for imc on asrock ?

If,for example i put +0.01 on SA the voltage will be ?

 

Ps:don't leave on auto,the values which are set are crazy, sa= +300 ,ioa= + 250 and iod = + 200.

Stock values should be 0.800 for SA,1 V for vccio.Z97 oc formula is better because you can actually see the default values and the applied ones after you set +0.xxx. Z87 formula uefi does not show them.
