Probably more like 1.35-1.4. You eventually start hitting a wall where an additional 100 MHz is quite costly -it's not linear..

20 minutes HCi at +3 bins core and cache with 2800mhz RAM at not quite tight but far from loose timings at bone stock volts, depressingly high though they may be.

It froze shortly afterwards which I'm 99% sure is cache related, considering I've traditionally needed more like 1.3v to stabilize there. This is absurdly complicated due to the high RAM OC and my core being so crap.

I can't do the standard "max core then max cache" deal because 42x or higher cache has such a beneficial impact on my core stability. Normally 46x requires 1.36 or more volts to be stable, but that much vcore requires VCCIN so high that it appears to destabilize my IMC. I'm doing a lot of shadow stabbing here in the hopes that I can get cache high enough to keep required vcore low enough to get 46x core with this RAM OC.

You must be asking yourself, is this worth it? Tweaking RAM at this level will not give you any real world gains.

It's either this or sit around feeling sorry for myself after losing the lottery with literally the worst 4690k I've read about.

Just trying to have some fun seeing how much I can get out of it. It's like a junkyard derby. redface.gif

I am revisiting - resetting my 24/7 O/C profiles with LLC at level 5. On the ASRock Z97 OC Formula this is the lowest level available.

Yesterday:
Warning: Spoiler! (Click to show)
In the BIOS:
CPU Input voltage = 1.7V
LLC level 5
VCore = 1.340V, Adaptive
Cache voltage = 1.2V, Adaptive
All C-States, Enabled

Corsair H110 + 2 x Noctua NF-A14 IPPC 3000, mounted on the front panel, blowing air inside the chassis. No other (chassis) fan running in my system.
Ambient (room) temp = 27.5 C




HWiNFO64 reset after all cores reached 100% load; screenshot taken 2 - 3 seconds before test completion => the Averages have real meaning.

Do you guys think it would be ok to run 1.445v for a 5Ghz OC on a 4790k? I've had the CPU for over a year now and will probably upgrade in a year or so, is it possible that it would die before that. When not under load the voltage does scale back and temps average around 78C on full load.

My 2 cents I think it's fine but expect chip degradation in a year. I don't think it would die but you are taking higher chances, as long as you can keep the temp down. I've been running a 5930k at 1.375v on adaptive voltage for months now and it's been ok, no sign of degradation and it's still ticking.

If you are cold sure, otherwise I wouldn't. Why not run 4.9GHz 1.36V or something like that? Usually the last 0.1GHz is a huge jump in voltage and minimum gain in computing power.

For DDR3-2666+, it's much rarer to find a capable IMC on i5's than i7's. Intel didn't bin them that way because they all officially only support 1600, but the quality difference is apparent when it reached customers who pushed the IMCs to their limits. As for pay-offs at high DDR3 clocks, if you can stabilize it, it will reduce your maximum latencies (boost minimum frame rates).

If you google, you'll see that most accounts of people running 4.9GHz - 5GHz 24/7 at 1.4v+ have survived for a year+. Leads me to believe that the few who didn't are not caused by voltage alone. It had to be spikes of voltages caused by motherboard anomalies or in temperatures when loops occassionally stall or whatever. These chips are quite robust when kept cooled and power states are used. Over winter, I've ran 4.9GHz at 1.375v for a few months and only have recently lowered to 4.7Ghz at 1.3v for lower heat output from my radiators.

Once more to the drawing board. 2800mhz CL 11 @ 1.80v. Livin' on the edge.

How is the ram OC going? I just started playing around and sure haven't my legs yet.

gskill sniper 1866mhz 9-10-9-28 T1 @ 1.53
seems to be my stable default

2000mhz 9-10-9-28 T1 @ 1.68
can boot Windows but gets squirrelly in Edge and during resets

How high ram voltage can the 4690k/4790k handle, is that a known value?
