trying to break benchmark records?

throw away all hardware now and replace with X99/Z170

Get a FX-8370 (non-E for higher leakage). All of the chips I ended up testing reached at least 8.3GHz on LN2. About half of them did 8.5GHz - 8.6GHz and the very first one I tested did 8.72GHz.

At this point the binning doesn´t really matter in the usual context, you´ll be Pll limited beyond ~8.64GHz anyway.

No way to break any benchmark scores on this platform.

Just about maximum CPU-Z !
I mean the maximum CPU-Z that I can do.
Breaking the whole record could be happen but needs something more like a miracle. smile.gif

Thank you so much for the all information you sharing everywhere.

Can you tell us more about "PLL limit" in detail ?
I always get excited about new concepts. smile.gif

The CPU Pll ratio together with the BCLK generate the CPU frequency.
For several different reasons the Pll cannot operate beyond ~8.64GHz without losing the locking.
When the locking is lost unexpectedly the system will usually halt or crash.

The issue can be fixed by adjusting certain Pll parameters (DC), however these cannot be adjusted by SW (requires JTAG). The only way you can improve the Pll characteristics without any special hardware is to optimize the operating conditions of the Pll. That can be done by calibrating the Pll supply voltage (VDDA) perfectly. This requires plenty of LN2 though.

A method for coarse hand tuning of the VDDA:

Ceil VDDA (Vmax)
Floor VDDA (Vmin)
Coarse optimal VDDA = In the exact middle of Ceil & Floor.

Ceiling the VDDA is potentially dangerous as setting it too high will fry your chip.
Usually the system becomes unstable before unsafe limits are reached.

What a great info , thank you.

I'm looking for a while after any 8370 or other last series FXs , unfortunately seems its very hard to find here if not be unreachable!
A simple 8 Ghz is a first dream , Can't imagine i could find a 8.6 Ghz chip.
But if that day comes , i think i can even handle JTAG !
Ofcource i don't konw a lot about JTAG , or haven't any idea to do what with pll parameters ,
But there are frineds i can get help for JTAG operation.
So , i will keep searching for chips and hope to get a pll limit one day and come to you. smile.gif
