That's water right? The higher you push llc the higher your temps will be, that alone will cause problems and why I like to sit on medium for cpu and high for nb.

It just means that it raises slightly under load, rather than drop. That's better IMO as you only want a higher vcore when it's required. There's one above the one I'm using for the CPU but that spikes too much for me.

Reducing LLC only reduces temps because of the reduced vcore you end up with under load, which is fine unless it reduces stability too.

And yes it is a custom loop, but it's in an HTPC case that sits in an AV rack so it's not as efficient as one with 360 rads etc.

No no, I've actually tested this on my saber, I went up 5c going from med to high and only gained 0.03v anti droop. It does add a bit of heat.

I'll try it with the same vcore setting then and lower the LLC one notch. I'm always keen to get lower temps! thumb.gif

I'm pretty confident that it'll just become unstable, and I'll need to raise the vcore setting to compensate.

Comp it with raising the ceiling voltage a little, on load it'l fall back down but its still lower load even with the higher idle v. The goal is to get the max load v to match what stable is, while slowly inching up the manual v setting, so like 1.425, should be 1.404 on idle and 1.356 on load.

I should also note I have both cpu and nb current capacity at 100% not higher, phasecontrols as optimized. ;p

Note: since you're on a 8320 not 8350, may need to have a base voltage of 1.437 or 1.44.

OK thanks, I'll crank those back and see how it goes. smile.gif

Not convinced by LLC. It still needs to end up the same under load to be stable and IMO it's better that it's lower when idle than the other way around.

Sorry wrong thread.

Think of it like this, at idle, you are rocking v with low amps, at load, you are rocking v with high amps, at idle it's negligible, but at load is where it is important, where the heat is, and the strain on the vrm, which also kicks out barrels of heat, you want to minimize stress in those areas. So low amps tiny bit higher v with exact v at load with high amps, works out better on the board and the chip.

OK. Well I can't test it now because I just returned it back to it's home in the cinema room and it doesn't display the BIOS properly through the projector. rolleyes.gif I'll have to get the monitor from the office and I CBA tonight. tongue.gif Definitely going to try it out tomorrow evening, Mrs Wolvers is out. biggrin.gif
