Help OC on RIVE

[tistou77]

Hello

I start to OC, for the moment I'm 4.4GhZ
I want to OC between 4.4 and 4.6GhZ (depending on Vcore required)

These are my bios settings, I can change some thing that is more stable?

About the memory I have of G.Skill RipjwasZ 2133 C9 4x2Go
I set 2400MHz C10 and tried using the profile "Load Tight 4x4GB Hynix Profile" (I think it's that Hynix I).

It's weird, the sub timings are AUTO and there is not the same values? it's normal?
between the CHA/CHB and CHC/CHDMust put its sub timings manually?

Thanks for your help 😄

Your timings look ok to me. It's probably your voltage causing problems. Your ram is only rated for 2133, it may or may not OC to 2400 even with extreme voltages.

I'm running some Corsair ram, rated at 2133 @ 1.5v, at 2333 @ 1.65v. That's as fast as I was able to push it. I think it can do 2400 at around 1.7v, but I'd rather not go that high myself.

I've seen G.Skill ram rated for 2133 @ 1.65v rather than the 2133 @ 1.5v like my ram. If yours is rated 2133 @ 1.65, you might not be able to get it any higher. If it's 2133 @ 1.5v, you might be able to do 2400 if you want to push it to the 1.65-1.7v range.

Keep in mind you will want to raise your VTTDDR in step with your DDR voltage. It should be around half, default being 0.750v with 1.5v ram. At 1.65 you would want the VTTDDR at 0.825v.

Hi,

If your looking for a 4.4ghz overclock your looking towards 1.3v + but becareful as you drive up in multi your going to need to adjust the vcore voltage i suggest running at 4.2ghz and finding a sweet spot on low voltage and take it down alittle for example:

I run mine at 4.2ghz 1.310 voltages with 75% vdroop with this info i know for a fact that if i drive up the cpu multi i'm going to need more but instead of aimlessly just bumping it i'll push the multi to x46 and then boost vcore voltages to: 1.320 and try to stress the pc (as this is just a little boost that way i can elimate the idea of needlessly wasting voltages). Once i've found a voltage that keeps the PC alive for 18hours, i will save those settings and declock the whole pc back to AUTO. and then stress the RAM and see how far i can go with tweaking them (i suggest you take this path too) instead of just aimlessly trying to get a stable PC and keep bumping voltages, do one thing at a time this way you elimate issues occuring.


Once you found a sweet spot for ram, save those settings and dump them back to AUTO. then OC your CPU only even leave the memory underclocked so the IMC can handle the pressure then find a sweet spot where your PC will stay online for 6-10hours and while in this time play games and stress the pc don't just rely on stress test programs as they are only doing a certian set of instructions. Once you found the sweet spot with voltages and BIOS settings for this, then dump them both together and stress the crap out of the PC and if it works you know you got a sweet setup.

Try this out (it takes days to overclock .. it isn't just a 5minute job even though the AI suite says it is :D) If you really want a rock solid high OC your going to need to be patient and take your time to elimate issues.

Also try not to drive your ram too high past its "sold" rate, I find with my 1600mhz i cannot push past 1866mhz and that is just one step up without having to really mess around with too many settings, you also will not see a huge real life performance change either so if your running 2000mhz + work on getting decently stable rams and tighten up your timings - oh and yes your secondary/third ram timings pretty much 99% always just setup at AUTO its the way the PC is maybe you could get around to tweaking these too but just note as you drive a higher memory OC your going to need to slack abit on your timings and maybe pump some more voltages to them to allow them to run correctly - also your VCCISO might need to be slightly adjusted.

My ram is OK to C10 2400 😉

I put the VTTDDR to 0.825v?

And it is better to put the CPU on Medium LLC (and therefore more Vcore) or High (and less Vcore)?

thanks for your help 😉

I see, I thought you were having problems with stability.

I would put the VTTDDR at half the voltage your DDR voltage. If you are using 1.65v, then yes, 0.825 VTTDDR.

As for CPU LLC, I have mine set to extreme. This affects the voltage drop when a load is applied to the CPU. At medium, your vCore should drop slightly when under load. Set to high, the voltage might not change at all. On extreme, the voltage goes up a fair bit when your CPU is working harder.

I have all my current capabilities set to max (180/140/140/140%). I'm not entirely sure what it does, but I think it removes any wattage limits that might be set.

My OC is stable (OCCT, HyperPI 32M and current use)
I just wonder if there are settings to refine

CPU Current Capability, etc....

Thanks 🙂

If you put it at 140% that'll help you, because that'll allow the CPU to suck up more juice and of course help your PC not crash so easily from your CPU needing more juice (this isn't saying boost VCORE it's saying use the option CPU Over-Protection/Current Capability in the BIOS).

Using 75% that should be High? setting that will give you a stable overclock on nearly any range of 4ghz/4.6ghz so if you are after a little less Vcore then yes keep this at 75% and SLOWLY tweak down your vcore until your PC crash's but remember to not change any other settings while you are trying to tinker your voltage down or you'll end up with a list of 50 things you just added to the crashs and you won't know where to start. Also do not just stress your pc with stress testing software, while they are good i find my self (not sure about other RoG members) but crashs/bsod and various other errors pop up in games as the way games are programmed and played on PC's it really involves more of the PC in the task at hand so you are able to find out if you have problems with your OC or system configuration settings.

I assume you have looked at the UEFI guide for the R4E bios? It could be more in depth on a few items, but overall a good guide.
