Hi guys,


I'm wondering would you drop the CPU Vcore to 1.424V vs 1.446 and memory by 266 or run 1866 with the increased cpu vcore?


Thanks!


System specs:

RIVE
64GB Corsair Vengeance 8x8GB 1866mhz
3930K @ 5ghz (50x100)
Custom Loop

Too open ended. What other variables differ between the 2? Memory timings, Temperature differences.

I myself am completely okay with 5ghz 2500K on 1.48v with 4x4GB 2133MHz memory at 9-10-10-27 1T. Even though it requires max safe settings for VTT.

Temperature is like 1-3C not much.

Memory timings I've left them the stock it's 9-10-9-27 I haven't messed with it. I know the memory controller is stressed with 64GB memory I'm running VCCSA @ 1.225 otherwise won't be stable. The higher memory speeds need a slight Vcore bump as well.

I say the higher the better. This is afterall, OCN.

I dont understand, your cpu needs more vcore to run faster memory speeds? Doesnt make sense to me unless your overclocking via the base clock.

This has been true since Sandy Bridge. I was going to do an article on my blog about it, but forgot all about it. I've noticed with increased memory speeds (not quite so with increased amount of memory), I'd need to add higher VCore to make the CPU/memory stable. Even adding more DRAM Vcore doesn't help, or increasing the VCCIO or system agent voltage.

Well it doesnt make sense but thats the case.

Im leaving it alone at the 1866 for now see how it runs the next few days

Good idea!
You paid for 1866MHz and it's only a small bump in voltage, it'll probably give the CPU more stability with extra voltage as a little bit of extra voltage can help with those random BSOD's that you sometimes get. You might even like to try 2000MHz? smile.gif
