Not sure BLCK OC’ing is the way to go on these cpu’s for MSFS either. You can get these suckers running real fast. But keeping it there is another thing
EDIT: The 7800x3d’s can hit 5.2 without breaking much of a sweat this method though. And 7950x3d well into the 6Ghz realm without getting crazy. I’ll have to revisit. Maybe up my cooling game. I’m already looking at water cooled dimms
EDIT: Yes, water cooled dimms. Stay in the 30ishC range in 1.6V+ huh, what volts? mine are into 73C Stress testing, add 12 degrees for the hotzone ouch. 10-15C from toping out, and without the gpu going. Dang Ram Oc’s and I can’t go higher on the voltage. My gpu is cookin my raml if I push harder.
EDIT3000: So this means I have hit a wall, for now. I’ve been trying to get to cl26 @6000mhz.
I guess everyone’s circumstances are different, networks, PC, usage patterns. I’ve only had mine for a few weeks but I did some before and after testing with cache over London with lots of pg and 3rd party scenery, and I found with cache on led to reduced stutters but did not eliminate them.
I wasn’t really expecting this after my xbox experience but I’m always happy to follow where the evidence leads.
As per the link, according to GIGABYTE’s info, it’s hynix.
But I’m not sure if it’s Hynix-a.
And despite hynix, it’s 5600, not even 6000, which is lower than Samson etc. The value of cl is excellent, but…
Japan also has such memories.
It is hynix-A guaranteed, but cl is as low as 40.
I’m having trouble choosing.
What items have you set for memory?
I’ve built a lot of PC’s, but this is my first time overclocking.
Is it OK to set the following 8 items in the BIOS?
tCAS(CL)
tRCD
tRP
tRAS
tRC
tRFC
VDD
VDDQ
Expo memory is unlikely to be available, so at best XMP.
In this case, like you, I could choose zskill 6000.
Alternatively, I can choose hynix but with a lower number of 5600 for some reason.
Which is better?
Or…
And the link without the heat sink (but HYNIX-A) is a memory that does not have such a thing at all.
In this case, everything seems to be self-configured.
Even with this memory, is it possible with 8 items?
If it is Hynix, then CL30@6000 1.4V VDD is an almost for sure thing. I would not be getting memory without heatsinks unless you plan on adding some yourself. Your video card will be right underneath, cooking your ram.My DIMMs/memory have hit 74C while stress testing. Then you have to add 12C for the hot spot. That’s 86C. I have to keep my tREF1 at 50000 because of heat, could go higher and will pass a stress test. Then I play MSFS and my gpu starts cooking my memory. This one is very sensitive to heat
tCAS(CL) 28
tRCD 36
tRP 36
tRAS 30
tRC 68
tRFC 500
VDDIO MEM 1.4V
VDD 1.47V
VDDQ 1.45V
These settings are not plug and play. This will very much depend on the quality of your ICs. And will be different with every kit at this level of OC. The only way to do this, is spend days running stress tests. Be prepared to reset bios, pull one stick to boot if your voltages aren’t right. Corrupt windows. and, and, and. I have at one point, trying for CL26 had my machine down for 40 mins with my bios refusing to reset/clear, and no post. I almost pulled the battery.
I do have memory timings that will work on most kits, and for sure on Hynix. These will require no voltage adjustments outside of stock expo/xmp voltages, but will require a minimum 1 hour run on OCCT. No way that kit hits 6000mhz at 1.25V. So, the timings would work at 5600mhz on 1.25V but to get to 6000mhz, voltage bump
EDIT: 1.25V is nothing. Those IC’s might be champions.
Big Edit: PLEASE!!! Let me clarify. You do not need expo memory people. It is a gimmick. It does not communicate in a special way with anything. It is the same as what xmp does. And XMP memory runs just fine on AM5. You will have to put a couple things in manually is all. VDDIO MEM is one (1.4V is standard), Infinity Fabric Frequency is the other I believe (2000mhz). Infinity fabric frequency dictates the memory controller frequency (It’s not a magic way the cpu and ram communicate). AMD is famous for marketing hype, don’t fall for it. Yes, they are great CPU’s. But there is a lot of BS in their marketing (Yes from the guy with expo memory. I messed that one up. Figured that out after)
VDDIO MEM is the voltages sent to the IC’s
VDD is sent to the DIMMs (The main one for high OC’s)
VDDQ is the voltage put to your CPU’s memory controller
EDIT: 36 tRCD on AM5 is more rare. Very few will hit that one and stabilize it (Buildzoid of LTT aka Actually Hardcore Overclocking even hasn’t hit that one on AM5). 37 is still one that not all kits will hit. 38, any half decent kit will hit
That is just fine. Hynix-a only matters if you plan on going down a very dark rabbit hole of overclocking as I am
Even Samsung IC’s are fine, and will overclock well (but not great). they melt at 1.5 volts. If I had samsungs, they would have already fried as I’ve had my memory into 1.53V so far (And I need to buckle down on my OC, I am doing it wrong for CL26 and know it. It is different than CPU OC where you start low voltage and gradually add. You start with high voltages on memory and work down. Just a bit scarred to plug in 1.6V, but I’m getting over it and will happen) That will mark the highest V’s I’ve put memory through. My old gskill drr4 samsung b-dies were insane, even with all 4 banks loaded
EDIT: I know, what’s with all the edits all the time? Stay away from Micron IC’s that is all.
In the end, I went to a memory store in Akihabara and was recommended this memory, so I bought it.
HYNIX seems to have this memory.
However, it seems likely that it is not HYNIX-A.
I was also told that if I try to select that memory at 64gb, I need to select an expensive 7000-8000MT OC memory.
The motherboard is ASROCK’s B650proRS, and I don’t have much technical experience, so I don’t think I can do OC like everyone else,
I’m going to try to build it anyway.
Because I use Google Translate for editing, I often have to rewrite because I sometimes look at the translation that comes out after I write it.
When there are significant changes that are not corrections of grammatical errors, I will include an editorial note.
That looks awesome, and AsRock motherboards are one of the best in AMD right now. I can help. I can send you pictures in private messages when you get built. Pictures of settings to use on Stock expo/xmp voltages. I am sure I can walk you through setting up PBO (Precision Boost Overdrive) and a general under volt too if you like.
Is that memory on your motherboards qvl list?
EDIT: QVL = Qualified Vendors List. Just want to make sure it’s compatible.
Might have to give up the fight. Had enough beer last night to get the courage to flood my poor Ram kit with some serious voltages. I went to 1.57 of VDD. When OCCT first started, it spiked into the 1.6V range Didn’t manage to stabilize it. Something else is holding it back. It sure wasn’t VDD voltage either. I’ll have to consult with the OC gods lol. It didn’t ever bluescreen or shut the PC down. errors inside OCCT. So I am, still close. Tried to bite off a bit too much at once maybe too. 2100mhz Infinity Fabric, while shooting for 6200mhz on the ram at CL28.
I recommend waiting for your MOBO manufacture to release new BIOS’es later this month / early next, that contain AGESA 1.0.0.7.b
There’s significant updates in this microcode release that will allow up to 7200MHz DDR5 (Early reports 8000 MHz is possible) on X670E. Perhaps this will bring improved RAM OC capability with existing kits. Of course YMMV…
I was doing this off AsRock Taichi. Just picked up the new bios yesterday 1.28as01 agesa 1.0.0.7.b. I actually took it off. It’s not as stable as what I was using. My original OC on my ram even threw errors. I flashed it back and stable. Maybe trying again with my original bios. The only thing I have to hit on my oc is 6200mhz, the rest is rock solid. I was close on my old bios at 1.53 VDD, 40 min occt run before errors
Just received my 7950x3d build (went for 64gb of RAM) however have some setup questions:
1)just wondering the best way to config everything for optimal MSFS performance - am reading the best way to ensure all the cores are being used optimally(I assume the PC already has the latest drivers drivers) is to ensure game bar is on and the cores should be auto configured? (note when running MSFS also running some apps in the background such as AIG) so assuming I need to ensure MSFS.exe and any related apps are assigned to the x3d cores which should happen automatically if game bar detects MSFS as a game - or do I need to follow some more steps?
2)In terms of monitoring in game/outside the game what cores are being used and the performance (fps ect…) - is the paid version of lasso best to use or is there anything else worth considering such as the nvidia fps counter?
3)are there any other performance tips - such as using rolling cache?
Sorry for getting to the party late. I don’t run mine like that at all. I don’t use gamebar, and I don’t set to auto. I set to “cache” This way it doesn’t park the CCD1 cores. It will use the CCD0 the V-cache cores 1st. But won’t hesitate to use the other cores if needed. This way, it doesnt matter what you do, your pc will always use those cores 1st. Very easy peasy. I don’t use process lasso, but there are others on this forum, and thread even that have some skills there. Rolling cache has been successful for me using a ram disk. If you look further up this post there is some instructions on how to set it up. and some further chatter about it after as some of the other guys figured out how to set it up for a set and forget.
remember this isn’t an x3d chip he is oc’ing memory on. You need 1.4V on vddio mem or blue screens 
Didn’t manage to stabilize it. Something else is holding it back. It sure wasn’t VDD voltage either. I’ll have to consult with the OC gods lol. It didn’t ever bluescreen or shut the PC down. errors inside OCCT. So I am, still close.
