Asus z790-e Strix Wifi II (new refresh) motherboard and G.Skill Trident Z5 F5-8000J4048F24GX2-TZ5RK

[theonecsm]

Asus Mods or Anyone:

I just bought the new Asus Z790-e Strix Wifi II motherboard (refresh) and according to the Asus QVL Memory List G.Skill 8000MHz 48GB (2x24GB) Trident Z5 F5-8000J4048F24GX2-TZ5RK is compatible (screenshot attached from Asus)

I am at my wits end trying XMP 1 and XMP 2 and can't get this memory to overclock even to 7600Mhz much less 8000Mhz.

I have the memory in slots A2 and B2 according to the manual.

I have also updated the bios to the latest bios - ROG STRIX Z790-E GAMING WIFI II BIOS 0506

Please explain to me how to get this memory to work at 8000Mhz otherwise I will take this motherboard back and memory as I am done trying to get this to work.

Here is the screenshot showing the QVL list for the Asus ROG Strix Z790-E Gaming Wifi II motherboard

in the manner of fact, I was helping a friend with a apex encore with the same. even with beta 06xx bios. in fact we find other bugs also. i will try to see what else i can find since he is ready to send the board back   Let me what else i can get and by the way make sure the keymanagement is not grey out

Hi,

8000MT on 2DPC will need a fairly reasonable IMC and as this is maximum validation, tuning can sometimes be needed.

The two key voltages for tuning memory are still MC VDD and VCCSA on 14th gen CPUs.

Increasing MC VDD (Memory Controller Voltage). Try values up to 1.5v

Tune VCCSA (CPU System Agent). A lower voltage might be preferable depending on the CPU sample, but increasing may also help.
Try values between 1.15v - 1.4v.

Sorry, this doesn't work, tried several MC VDD voltages up to 1.5 no go and VCCSA as well uping to 1.25, didn't want to go higher than that.

Out the box the memory should be supported in XMP 1 or 2, shouldn't have to play with timings or voltages if it is stated on Asus QVL list and listed under XMP.

Would I have this problem with the new ASUS Z790 ROG Maximus Apex Encore without having to adjust voltages or timings?

I just want to run XMP and it work at 8000mhz

[Silent_Scone]

Some CPU might need more than 1.25v VCCSA for these frequencies. Up to 1.4v is not an issue.

The Encore is only 1DPC as it’s geared more towards overclocking potential, so the short answer is yes, it has an advantage. Despite what may be assumed from certain marketing material, XMP does not guarantee automatic overclocking. The tighter the timings or higher the frequency compared to stock specifications the more likely chance there is that the user will need to manually make some adjustments for stability.

[theonecsm]

Thanks for your reply, I will try up to 1.4v for the VCCSA before giving up.

Do you mind sharing your settings for your Apex z790 as far as timings, voltages, etc, screenshots would be nice?

Were you out of the box on your ROG Apex Z790 able to run 8000Mhz without tuning, if not, please post your screenshots as I have decided to takes this board back and swap to the Apex Encore.

Thanks

Keep in mind that your CPU also has some affect with how well you will be able to overclock your RAM.  The IMC (integrated memory controller) is part of the CPU so the silicon lottery comes into play there.

[Silent_Scone]

I've posted some results here, however, achievable timings, frequency and voltage will vary from system to system due to CPU variance (and this case the motherboard used). The CPU IMC strength and variance when operating past stock frequencies is nothing new, this is why no vendor can make assurances for such things. I often recommend users opt for a memory kit one or two ratios below the maximum validation if looking for plug and play.

This is the same memory kit. (the VDD and VDDQ voltages are a polling error due to having multiple instances of CPUZ open. VDD and VDDQ voltages are 1.61 and 1.51v respectively for 8200/8400 - primary, seconds and tert timings are tuned manually)

So you are saying I got a ******ty 14900k then? I mean ****** I would think it would have a better IMC.
