To get the most out of gear 1 ddr4, you need single rank b die or hynix d die if that even exists (8gbx2), and maybe a z790 board.

It's rated up to 5333 OC.

13700K should be fine for 4000 G1, but the board helps.

It should be on Kingston Fury Renegade sticks, starting at 3200 Mhz and are currently very cheap.

2x16 Micron Rev B too but you can no longer buy it new.

DR vs SR, at 4000 the difference is CL15 on DR, CL14 on SR. DR adds interleaving, but the lower timings still seem to be better.

For your current CPU have you tried raising SA to 1.35v, VDDQ to 1.4v and Vram to 1.55-1.6v to achieve gear 1 stability?

This kind of works on my 12600k, but bricks e core stability and becomes unstable with any CPU overclock.

13th gen chips seem to be be fine with 4000+ G1.

 

You should be fine.

 

Not with a B660 mobo that can't even use XMP. Z790 would be your best bet. If can't do 4000 gear1, you could opt for higher frequency like 4200?

 

Well, I also have i5-12400, and it can work relatively stable on this MB at 3600MHz gear1 (though I didnt test it thoroughly ). So i supposed that the problem lies mostly in AlderLake (non K) IMC.

What are your voltages?

VDram = 1.488V (HWINFO64)
VDDQ TX = 1.4V (HWINFO64)
SA VID = 0.904V (HWINFO64)

 

What are your voltages?

 

Oh forgot about the mobo.

Not sure how the tuf B660 is, but even if it supports SA voltage, dram is usually capped to 1.45 on non Z boards.

If you want a shot at 4000 G1 you should get a Z790 too as Telstar suggested.

 

How high does the vram voltage go on your board?

You might need up to 1.6v to stabilize 4000CL15 G1.

Like my H670 only goes up to 1.45v, looks like its going to be using some new Kingston Renegade ram I just found for cheap, so whatever it does in G2 at 1.45v with whichever I3 I pick soon.

 

Hi guys. I have an question.

Hi. I have 12900K stock 4880mhz ( 60-70C in game )

32 GB 2x16 GB DDR4 3600mhz in GEAR 1

Palit Gamerock Pro OC rtx 4090

1300W Seasonic Platinum Prime

Aorus Elite DDR4 Z690

Windows 11 2H22. Updated new nvidia drivers.

I have performance question in Cyberpunk 2077

I used 1440P,DLSS QUALITY,RT PSYCHO,rest ultra for testing fps.
Test place was near hotel , when you leaving apartment in beggining on game and talking with Jackie.
So driving there in loop i have fps between 80-90fps with gpu usage 80%.

I compare the same scenario and place with someone with Rtx 4090 and 13900K and he have average 20-25 fps more than me, 100-110fps. Is this possible that 13900K is so fast or its my system or my ram in gear1 ? thx
I have updated drivers.

 

Gpu usage 80% suggest that the CPU or RAM is bottleneck.

 

Looks like it can supply required voltages
System Agent PLL Voltage from 0,9 to 1,845 V
Memory Controller PLL Voltage from 0,9 to 1,845 V
IVR Transmitter VDDQ Voltage from 0,7 to 2,2 V
DRAM Voltage from 1,0 to 1,8 V

 

Hi, there. I relatively new to ram OC and have a simple question.

Suppose we have 2 CPU - one with weak IMC ( i7-12700(non K) ) and one with good IMC (i7-13700K).
And we have DDR4 kit 2x16Gb dual rank Samsung B-die (F4-3200C14D-32GVR).

With weak CPU (12700) i was able to overclock it to 4000Mhz 15-15-15-32 CR1 in gear2 mode and pass testmem5 anta777 extreme1.

Will this RAM kit guaranteed to work (pass testmem5 anta777 extreme1 in same conditions) in gear1 mode with CPU with decent IMC (13700K)?

I ordered 13700k and I have to wait for 2 weeks. But I need to decide now - should I keep this RAM kit, can it work in gear1 mode.

System specs:
CPU: i7-12700 (non K) (and i7-13700K in future)
MB: asus tuf gaming b660m-plus wifi d4 (bios 1620)
RAM: g.skill ripjaws V dual rank 2x16gb (F4-3200C14D-32GVR)
OS: Win11 22H2

Thanks in advance.

I doubt you will be able to run 1t/cr1 in gear 1 with the same tmings and clocks with DR b die. Gear 1 will likely need 2t.

 

Yes, you are right. Forgot to mention it in the first message. On my MB gear1 works only with cr2, while gear2 works fine with cr1.

 

Thanks, I didnt know that.

 

Well all the settings I can run on the 10900K in 1:1 work the same in G2, no improvement or difference. The IMC blocks the ram to 4000 G1 on the 12600K, and even with that as I've just spent ages testing, I can't OC the CPU at all to maintain stability. The ram I have is not limited in 1:1, only the IMC is.

The only thing that gear does is change the IMC : Ram freq ratio, so G2 sets it to 1:2. The ram running at the same frequency just halves the IMC frequency in G2, basically gears is not a ram setting, its purely an IMC setting.

So one way to test DDR5 right now I don't see many people doing is set G4 just to see how high the ram can go, any higher on the ram means the limitation is the IMC in G2.

 

Thank you for answers, I appreciate it.
Well, I have another question if you allow me.

System specs:
CPU: i7-12700 (non K)
MB: asus tuf gaming b660m-plus wifi d4 (bios 1620)
RAM1: Goodram IRDM Pro Deep Black single rank 2x8gb (IRP-K3600D4V64L18S/16GDC)
RAM2: g.skill ripjaws V dual rank 2x16gb (F4-3200C14D-32GVR)
OS: Win11 22H2

My old kit was Goodram IRDM Pro Deep Black [IRP-K3600D4V64L18S/16GDC] 2x8Gb single rank Unknown die, presumably Hynix C-die.
I used it at 3400 16-18-18-38-G1-CR2 and got at Aida64 ~56000 ~52300 ~53900 MB/s ~59ns.

When i changed it with 2x16Gb dual rank Samsung B-die (F4-3200C14D-32GVR).
I tried them with same timings and configuration, except RTL 69/69 71/71 unstead RTL 25/69 25/71. At aida64 I got lower results: ~52000 ~52100 ~53400 MB/s ~59ns.

Read speed decreased by 4000 MB/s, copy speed decreased by 500 MB/s. I tried another 2 b-die kits 2x16gb dual rank. The results are reproducible. These B-die kits somehow slower than my old kit.
I read across internet that B-die is the best RAM chips, so that aida64 results was somewhat unexpected to me.

So B-die is not fastest chip at all things equal? Or that RTL settings did that? Or single rank is faster than dual rank (on internet many people say dual rank is faster) ?

 

Well first of all you are testing stock vs stock? So why would there be any difference?

Samsung B die is the best DDR4 when overclocked and tuned.

DR is better than SR when using just 2 modules as it adds interleaving:

https://en.wikipedia.org/wiki/Interleaved_memory

Interleaving can be achieved on SR with 4 modules, DR with 2 modules.

However, 2xSR overclocks higher and does lower latencies than DR, which can beat the loss of interleaving.

But to get 2xSR on samsung b die, you can only use 2x8 Gb modules, the only DDR4 SR 16 Gb modules are Micron B die. The latency is a lot worse, but its 2x16 SR .... this only really helps if overclocking in gear 2.

2x16 samsung B die manufactured since end of 2019 is the best DDR4 you can get for latency. It also costs a lot more than all the other DDR4 ICs.

The biggest advantage samsung b die has is being able to hit very low trfc, around 340 at 4200, and less at lower clocks. Micron needs close to double that to even boot.

 

It was not exactly stock(3200c14) vs stock(3600c18). It was in the middle (3400c16 trfc 512). I expected that read/write/copy speeds should be roughly equal or b-die shoud be better.
Well, after yours explanation it looks like b-die is better only after good overclock because it is better at overclocking (with better timings). Thank you.

 

Yes, gear1 vs gear2 has better latency (like 75ns vs 60ns). If your PC can run cr1, and it is stable then use it. Otherwise use cr2.
