4x8 migjt require different CAD BUS and RTT Values.

24 24 24 24 maybe wont cut it, you would probably need something like mine. Im not sure what to run for RTT Values as I never had 4x8.


EDIT: Safe Mode Run with an AllCore at 4850MHz

Can someone tell me if these results are bad or normal ? I am not searching for the biggest overclock, just something that is good enough for a 5600x. Thanks.

 

[Annihilation]

So far a good result for dual rank e-die

 

[freeagent]

^^

That is why I want to buy an Intel to play with, just to see that number in my latency box

 

[ADB1979]

Something wrong with L3 cache 29..9ns ??? anybody know why.
my spec in Zentimings.

thanks.View attachment 192651

Hell yeah there is something wrong... Horrible L3 latency and lame L3 bandwidth.

Try again at default settings, could be an overclock problem.

 

[calebwpb]

I7-4960X al 2021 no bad

 

[FilipM]

So close to sub 50...

 

[freeagent]

Nice man, how do you get it to run so long? When I try its only a few minutes..

That's some solid tweaking right there, nice.

3933CL15 1T was doing my head, passed 24 runs only to spit itself on Cycle 25. Moved to 2T and never looked back really, the performance penalty of 1T vs 2T is really minimal.

RTT 0 0 5 and 24 20 20 20 as in the pics is stable. RTT 7 0 6 and 60 20 20 20 is also stable, 25 cycles.


I am using 1.49VDimm. I can most likely get to 4133 and sub 50ns, but not willing to assault my system with more volts than this


PS. Ryzen Dram Calc Benchmark (Unrelated to this thread )


PPS. I included TM5 that I use. When you start it, you can go Load Config and Exit. The correct config is included (cant remember which one it was.) Try it out, it should say 1usmus in the log window

 

[Cowboystrekk]

Impressive numbers FilipM. What is your cpu-voltage at 4850MHz? I can do 4700 at slightly over 1.2V, but my cooler struggles a bit.

 

[FilipM]

I usually run various PBO settings as that in combination with Curve Optimiser works really good.

For the sake of the benchmark, that was 4850 allcore at 1.35 ish

Filip you're pwning this competition.

My results with 32gb hynix chips.

 

[Cowboystrekk]

At 55ns here with 4.7GHz on my 5600X, but struggle with bad bin B-die.

You should be able to do 20 or 16 tFAW and sub 500 tRFC, tRDWR might do 10 or a bit less and scl should do 3 or 4. That will improve latency a lot

 

[freeagent]

That last .5ns is always the hardest

 

[FilipM]

TRC 75? There is your half nanosecond

That stable btw?

Reduce tRC to 40-50 and I bet that gives you that 0.5ns edit: FilipM was a bit quicker than me

I know she looks a little sloppy.. but she's stable like that, I could daily it. If I switch to 14-14-14 and keep the CPU speed I could do pi32m benchmate edition in under 6 minutes with those settings

Good advice, 16 tfaw and scl to 4, just rebooted and it took. Anything under 650 trfc won't post, limitations of hynix ram. Lowered it a bit more to 670 though.

 

[FilipM]

tRC will be better at 57, not 56

tRC - Row Cycle Time:
The minimum time interval between successive ACTIVE commands to the same bank is defined by tRC.
tRC = tRAS + tRP

tRRDL can probably be ran at 6

 

[Cowboystrekk]

This is how far I get with my garbage B-die. I can run them at 1.5V and lower tCL to 15, tRCDRD to 16 and tRFC to 240, but get lots of errors since they overheat due to GPU sending hot air right at them. I know my tRAS and tRC are weirdly low, but they are stable and system got a tiny bit faster vs following the formulas.

 

[FilipM]

tRFC Scales with Voltage, hates Heat. Your tRFC is already very tight as it is, maybe try relaxing it a bit so you can try running tRCDRD at 16.

I tried but tRCDRD wont go below 17 even with tRFC at 290, and tRFC matters more in gaming so if I must go 300+ to lower tRCDRD I prefer tight tRFC Running without GDM on is also hopeless. Prefered my good binned micron rev Es, they were slower, but I could run cl15, tRP 11, gdm off, 1t at 1.44V 3733. 20 tRCDRD, 56 tRC and tRFC 525 on the other hand...

 

[freeagent]

Now were talking..

 

[FilipM]

Nicely done

Those sticks are really high bin. Run TM5 on it, if its stable, god damn

Impressive! Good job! Question: Why do you run vddg ccd and vddp at that high voltage? You would probably be fine with 900-950 ccd vddg and 850 vddp. This lowers cpu consumption a bit and can improve temps slightly. Sometimes this can improve stability aswell
