G.Skill DDR5 32GB 7600Mhz Trident Z5 Royal - does not work on its frequency! help me figure it out

[anton2014lev]

Hello everyone! First time on your forum.
Recently bought myself a new computer.
And the RAM works stably only at a frequency of 7400. At factory parameters and a frequency of 7600 - during testing the memory crashes on the 15th second.
Base voltage The system parameters are below:
>> Intel Core i7-13700KF 3.4(5.4)GHz 30MB s1700 Box (BX8071513700KF)
>> G.Skill DDR5 32GB (2x16GB) 7600Mhz Trident Z5 Royal Silver (F5-7600J3646G16GX2-TR5S)
>> Gigabyte Z790 AORUS PRO X (s1700, Intel Z790)
The processor scored 75 points on the internal motherboard test - but this is a mediocre score (~90 is considered good), I don’t know if it’s worth paying attention to this indicator in my case.
The motherboard supports frequencies up to 8200+. There are profiles for RAM for each chipset manufacturer - but they do not provide stable memory operation.

I'm gonna give it to you straight, there is a chance your processor cannot run 7600 - and this is further compounded by the poor motherboard choice. This claim that it supports 8200 is quite extraordinary - it's very unlikely that realistically, you will ever run anything at 8000 on a 4-dimmer motherboard.

My advice is apply XMP, reduce its frequency to 6400 and start increasing - testing on each step - 6800, 7000, 7200, and see what works for your chip and motherboard combo.

 

[JrRacinFan]

I read up on that kit a little. Looks like there are quite a few others not able to get the rated speeds and the ram starts throwing errors around 7400. Best I can say is try @Dr. Dro 's advice with testing on each step up.

Using the same board here, your IMC quality is a major factor for running higher memory speeds.

is something wrong with the site.. -_-'

Я скажу вам прямо, есть вероятность, что ваш процессор не сможет работать на частоте 7600 - и это еще больше усугубляется плохим выбором материнской платы. Это утверждение, что он поддерживает 8200, довольно необычно - очень маловероятно, что вы когда-либо запустите что-либо на частоте 8000 на материнской плате с 4 диммерами.

Мой совет — используйте XMP, уменьшите частоту до 6400 и начните увеличивать ее, проверяя на каждом шаге — 6800, 7000, 7200, и посмотрите, что подойдет для вашей комбинации чипа и материнской платы.

There is a profile for my memory at 7600. But it doesn't fit - when you set it up, memory crashes during a load test. Therefore, I think to experiment with increasing the voltage to 1.4 - 1.47 or 1.5. The motherboard supports memory up to 8266 (you can see it on the website) and there is a section where the guys overclock the memory on this board. Indicating the memory manufacturer, timings, and voltage.

I agree with you, but it looks like your kit is different from the kit in question.

 

[RootinTootinPootin]

its a 2x24GB 7600MHZ G.Skill kit..M-Die, his is probably A-Die..

a bit relevant, but my reply still stands, not all chips are guaranteed to run whatever speeds the sticks the user buys as the higher memory frequency highly depends on IMC quality and other factors as well, I have binned all my chips and all so far runs 8000MT's and beyond (2x13900KS, 1x14700K, 1x13600K 1x14600KF all binned using the ROG z790 Apex Encore)

Memory overclocking on Intel doesn't just depend on the memory VDD and VDDQ.

I also have an A-Die G.SKill kit (2x16GB at 6400MT's) that run 8200MT's on the Apex but rarely runs 7600MT's on any of my 4-dimm Boards (z690-E Strix, Maximus z790 Extreme, Gigabyte Aorus Pro X)

Such frequency is extremely diffficult to achieve on a motherboard that has four memory slots. Not to mention many processors have difficulties achieving these speeds themselves, especially those that are sold as Core i5 and Core i7. It is not guaranteed on a Core i9 either. I cannot lie - it is possible that you will never reach 7600 on this motherboard and processor combination.

I would consider 7200 to be more realistic and acceptable for 24/7 operation. However, it shouldn't be a big cause for concern, the performance difference between these two speeds should be rather negligible.

The Apex Encore is a game changer, though. This motherboard is supremely good and specifically engineered to achieve the highest memory frequencies out there. The volts I needed to get 6400 stable on my MSI Z690 Ace were awful in comparison with the Apex Encore and it's the exact same CPU that was used on both. Even then if the CPU itself is a dud, not even this motherboard will save it

 

[Assimilator]

But your CPU does not.

I made an edit above, either ways, I do own several 4-dimm boards and compared to the voltages used on the Apex Encore, they are really not far off when being used on my 4-dimm/2DPC boards, like I said, its always the IMC, all my chips are binned with an IMC grade around 80 (89 being the highest grade so far on a sample of 13900KS) and above, IMC grade below 80 will only run 8000MT's at pure brute voltages, while lower than 8k will be a walk in a park.

 

[anton2014lev]

I repeat, at a speed of 7400 it works PERFECTLY!

 

[phanbuey]

Increase SA voltage.

Try 1.30v and run xmp test. Then bump up to 1.32

 

[RootinTootinPootin]

Increase SA voltage.

Try 1.30v and run xmp test. Then bump up to 1.32

for that frequency 1.25 should be plenty, also not just the SA voltage, also other voltages such as the VDDQ_TX(CPU) and the VDD2(IMC)

someone who doesn't know what those voltages are for might fry their chip, so do change the values with caution and do it accordingly.

It's not - on my setup 13799kf XMP 7600 is only stable at 1.29-1.3v. If i set it to auto and let it float back to 1.25 it BSODs.

different boards react with voltages differently, might be that much for your case, might be less for others, on my Strix z690i, I run 7400MT's on the 2x16GB A-Die kit with the 13600K I binned with just 1.25v on SA and IMC around 1.2875v(BIOS) with the sticks on 1.45vdd/vddq with CL 34, CL32 needs a tad bit more like around 1.48v.

I mean that's fine and all but 1.45v DDQ/TX usually auto sets with high-end XMP, so typically those don't need to get pumped - from FAFO i can tell you what worked to stabilize my 7600mhz kit on a 13700k.

your IMC might as well be capable, its not the board or the sticks, point is its always and will be the quality of the IMC. I have seen 13700K's that does 8k MT's its nothing new if you know how IMC binning works, and not play the russian roulette on silicon lottery.

 

[JrRacinFan]

Yup! I agree with you. The JEDEC standards are anywhere from 4000 to 6400 at 1.1v on DDR5. So when you get these highly clocked they are rated UP TO **xxx insert speed here**, essentially overclocking out of the box.

 

[phanbuey]

very loosely the 4 voltages are:
1. SA - system agent is the primary voltage that controls volts to the IMC
2. VDDQ-TX - signal strength between IMC and Ram kit
3. VDD2- (DRAM) volts
4. VCCIO - signal strength between IMC and CPU

The 3 bottom ones SHOULD already be preconfigured and should auto set correctly by the board and XMP (1.4V in your case for VDD), VCCIO is the one that will increase thermals on the CPU - to stabilize on a weaker IMC or a droopy board you will need to increase SA volts or loosen the timings/speed on the kit, VDD shouldn't really do anything if the kit is stable at XMP - and those kits *should* have been QA'd at the factory.

In some cases the board can autodetect and yeet subtimings too tightly (TRFC etc.) - but you shouldn't have to touch those at XMP. Bios updates can help with this and memory compatibility in general, so do make sure you're on the latest bios as well.

I'll throw my hat in the ring here. Testing a fair amount of motherboards, those QVL lists are BS. It is just a dick measuring contest for vendors. 7400-7200 is more likely the "highest" stable frequency for that Gigabyte Z790 AORUS PRO X with 2 DIMMs. These QVLs are done with a golden sample CPU and without regards to the CPU voltages needed to reach those speeds. Sure 8200 MT/s works with System Agent at 1.5 V, but that's not going to be safe long term.

That being said, lets assume 7600 MT/s will work. You most likely have to adjust the CPU voltages yourself.

Try:
SA: 1.25V
VDDQ-TX: 1.35V
VDD2: 1.35V

If it works / passes memory stress tests, lower the SA first to 1.2V. If not raise it to 1.3V Go again. Pass and now lower the other two to 1.3V. Repeat until you have the lowest voltages each for all 3.

For reference with the ASUS Z790 Apex I only need SA: 1.15V VDDQ-TX: 1.25 VVDD2: 1.25V for 8000 MT/s. One of the benefits of a 2 DIMM slot motherboard, you get away with lower voltages.

I made an edit above, either ways, I do own several 4-dimm boards and compared to the voltages used on the Apex Encore, they are really not far off when being used on my 4-dimm/2DPC boards

I had a different experience. I need 1.35 SA for 4slot or more for 8000 MT/s, with only 1.15v needed for Apex. Similar for TX and VDD2.

, like I said, its always the IMC, all my chips are binned with an IMC grade around 80 (89 being the highest grade so far on a sample of 13900KS) and above, IMC grade below 80 will only run 8000MT's at pure brute voltages, while lower than 8k will be a walk in a park.

Igor shown that the MP value is meaningless. Mine a 72, yet 8400 is stable and 9000 boots. I had another 14900K and it could barely do 8000 and it had a 82 score.
