no worries. 1.45V is my baseline. wink.gif

use LLC 5
higher LLC is intended to translate to less vdroop under load. I'm with jpmboy, 5 is good.
post #1133 of 7219
I'm also seeing 3-4 degrees lower core temps with BW-E than with HW-E.
post #1134 of 7219
Just set LLC to 5 with Vin set to 1.93V in BIOS.
AISuite now reports 1.92V wiht no load and 1.90V under IBT with Extreme Load enabled.

Good news is that with LLC=5 my temps are much better?! Or is IBT playing tricks on me?

I've left it on auto for now. One curious thing I saw was that Aida would show me stable at 0.9 SA manually, but stressapp in Linux would quickly find errors. I started ramping up 10mV at a time but ran out of time to tune so left it at auto for now.

Also, I found if SA was the ultimate deficiency, then more VDIMM often made it worse. So start with SA and then add VDIMM has been my experience with both HWE and BWE.

Ditto on the cache 3.7/3.8 wall and I need a big jump in volts to get to 3.8 stable and corresponding heat.

Filmguy, I am finding the BWE chip to run cooler for any given OC than HWE even though it has more cores, so I'd be surprised that you are seeing more heat than an even larger Si feature size, but I don't have a 4xxx to compare.

At least the ASUS bios is throwing plenty of volts at everything in auto which makes it work, but obviously produces more heat. Check your SA and cache voltages under load? If they look reasonable then I'd check for cooling loop issues.

All things considered with your configuration, that's quite good

It's always been like that on BWE, even stock. Maybe an error?
Cinebench etc. all report correct scores so no throttling.

What's with the 126 bclk?

My XMP profile sets it on 125MHz and I simply started from there.

Must be running 125 strap like me - I'm doing 126.4 BCLK.
