Z490 fast ram experiences

fusseli · Nov 5, 2020

Built my 10700k with a Gigabyte Aorus Ultra mobo and T-Force DDR4-4500 CL18 1.45V because it was crazy fast and mobo supports it.

Ram works flawless loading XMP and cpu benchmark scores show a difference. My frustration is that I cannot seem to get a stable overclock, of any kind, with the 10700k at the same time. I will get BSOD for memory error.

I am considering going back to a DDR4-3200 CL14 1.35V since it's almost as fast and a much closer to nominal ram speed for the 10 series of 2933/3000 MHz.

Any suggestions?

What is your IO SA voltage?

Right now they are on Auto:
VCCIO 1.199V
VCCSA 1.332V

also, cpu-z for 5.1 all core on either ram FWIW:

Cpu is at 100c? Try 1.25v for both IO SA. Reduce your cpu clock to 5ghz.

fusseli · Nov 6, 2020

I can run 24/7 stress test in Intel XTU on all cores at 5.1, it will oscillate 80 to 100C and throttle. If I bump to 5.0 it does the same and hovers 70-80 C.

Do you think thermal throttling is effecting the 4500 MHz ram stability?

mrthanhnguyen · Nov 6, 2020

Maybe your cpu imc cant handle at that speed. Did u run hci or tm5 to test the ram? Put a fan on those ram sticks. Some ram is sensitive to temp.

fusseli · Nov 6, 2020

I changed IO and SA from auto to "normal" and that put them at 1.2V and 1.08V. Seems cooler now.

It was not stable turning down IO and SA votlages. I swapped the 4500 CL18 back in and notice "auto" has them at 1.386V and 1.428V vs. what they were before with the 3200 CL14.

I think I will just try 2-core 5.1 and all-core 5.0 for a while. Not sure why I get the massive heat spike going to 5.1 all-core. Oddly enough this is my best cpu-z score yet running this way: https://valid.x86.fr/38c4xk

The instability is just too terrible with this 4500 MHz CL18 ram kit. I cannot run stable while gaming even at 100% stock with no tweaks beyond enabling XMP. FWIW this ram kit is not on the QVL for the Z490 Aorus Ultra.

I am switching to a 3600 MHZ CL14 ram kit that is on the QVL. This is theoretically a scosche faster than the 4500/18 and hopefully runs much more stable. with the 3600 IO and SA voltages are at 1.243 and 1.332 on "Auto"

cst1992 · Jan 17, 2021

CPU hitting 80-100C is a problem.
Could you put CoreTemp or RealTemp shots for when it hits that temperature? Maybe an issue with the cooling.

fusseli · Jan 17, 2021

I think the temperatures were related to the IO and SA voltages being set very excessively high automatically due to trying to run ram at 4500 MHz

CPU overclocks can reduce overclocked RAM stability. I'd remove the CPU overclock and check the stability then in case you overclocked the CPU.

Yeah I removed the CPU overclock and found the system wasn't stable all stock with nothing but XMP turned on. No bueno

Reduce the Ring Ratio to 300mhz less than CPU core clocks or back to default 43, overclocking the ring ratio can make the CPU run very hot and also affect stability.

Thanks for the suggestion. I have not ever overclocked or changed the ring ratio.

I am getting okay results so far with the 3600/14 ram. It is actually beating the 4500/18 in Passmark and Userbenchmark and a few others. Fingers crossed for stability so I get get back to OC on my 10700k!

phanbuey · Jan 17, 2021

4500Mhz is at the bleeding edge of the IMC - basically anything over 4200 is hard to get stable from what ive seen, anything below that seems really easy. Try putting your kit to 4100 or 4133 and tighten timings.

Arctucas · Jan 17, 2021

Your first two CPU-Z screenshots show 1.56 VCore, and the validation link you later posted shows 1.45 VCore. There is the cause of your heat issue.

Does that processor need that VCore?

That is due to Aorus Ultra doing "auto" voltages and attempting 5.0 all core turbo. That plus the VCCIO and VCCSA on "auto" being really high are what were causing my issues.

Still very high. You really shouldn't need more than about 1.32-1.35 vcore for 5.0 and 1.4 for 5.1... Most samples are 5.1 stable around 1.36 v.

You may have gotten very unlucky with yout sample, but those volts are way way higher than what are typically used.

Tatty_Two · Jan 17, 2021

If my memory (no pun intended) serves me correctly, the max recommended IO and SA voltages for 24/7 use is 1.25v, I always set manually. If I might suggest try your 4500mhz ram with manual settings exactly the same as XMP for the main timings, leave the rest on auto, re-boot and see how they play then, my ram (in my specs) happily run at 4500mhz but even at their stock speeds of 4133mhz they are not stable with a CPU overclock when using XMP, as soon as I manually input the timings and voltage (I increased the voltage very slightly) they were fine even with tightened timings and have been for several months now.

OK I will try and lower vcore and cap the IO and SA.

I just ran a couple hours of CPU stress on Intel XTU and seem to be thermally stable, floating between 60-80 C and not exceeding 80 C. System seems stable now too. Running ram at 1.45v 3600/14.

Hi,
Yeah that's crazy 3600c14 1.45v lol
My 3600c16 only needs 1.35v

How hot do your dimms get with 1.45v heck I don't even need that much voltage for 4000c16 1.43v is about it.

That's an XMP profile on the XPG D60G: 3600 14-15-15 1.45v, not gonna mess with it.

AUTO tends to overvolt, sometimes a lot.

1.3 VCore would be a good starting point, and adjust up/down from there.

I have a temp probe in between the DRAM and it is saying 27 C. So warm but not hot.

No doubt about that. As we can see here Auto is doing crazy high voltages for me here, not a fan. Think I'm going to sell the 4500/18 ram.
