Thanks a lot!

btw, there is no point of tRAS at 32. It‘s a sum of tRCD and tRP so it can‘t go lower than this and be effective. 
34 in your case is the optimum. 

Yeah, I was not sure about the tRAS. Somehow, from my testing, I saw a latency decrease from running it at 32 instead of 34. Also, I have seen formulas not only like you say tRCD+tRP, but also tRAS=tRCD+4+tWR (32 if you put my values in) and tRAS=tCL+tRCD (31 if you put my values in). I would leave it even at 31 but at 31 it starts to BSOD for me with memory_managment errors. Which seems weird if it automatically defaults to sum of tRCD+tRP then why become unstable?

 

Try it yourself, I am curious about your results.

 

When I get home I will also double check. But I am pretty sure that it was an improvement because I did very rigid RAM OC testing, even buying new sticks just to try to OC and stuff.

 

This was my best result:

Are you using XTU or Control Center 2.0?

I actually use both, but the Control Center I use only for fan adjustment. I think I have mine set to performance all the time because my CPU is always at 5GHz no matter the load.

 

I use XTU for everything else. Mostly for statistics about my CPU. When I do CPU overclocking or something I first test with XTU and when I have found stable values I make them permanent in BIOS.

 

If you enable Real Time Memory Changes in BIOS (or it was named something similiarly) you can make RAM timing changes on the fly in XTU, even the Tertiary timings. This option is available only in unlocked BIOS or the dsanke BIOS for example. If you have no hardware flasher, I actually have one BIOS from personal collection that I could send you. It was made specifically for me and it was latest BIOS but just unlocked and flashable through windows. I have a PCSpecialist model so beware, but I'm pretty sure it doesn't matter.

 

I hate that the BIOS is half broken for memory overclocking. For example, have you noticed that it is impossible to switch command rate to 1 (CR2 is defaulted no matter the choice). On unlocked BIOS you have the menus for Tertiary timings but none of them actually do anything, you can set whatever values you want they dont stick. Then there is the weird 3400 bug. Like I am 99% certain 3400 would work if the "Retrain on Fast boot failure" (or something like that) actually would work. You can choose disabled or enabled it makes no difference. Broken entries that change nothing. They are there but they have 0 impact.

 

I do have one more trick up my sleeve, I am thinking of downloading ThaiphoonBurner again and try writing a new XMP profile on my Ballistix. And in the new profile I can customize the timings even more. For example first thing I would like to see if it will accept command rate 1. Even though the BIOS doesnt register the change maybe it will read correctly from SPD (XMP) and apply it correctly.

 

Sorry for my rant🤣

Without much play with the secondary timings, stable 3333:

 

 

 

I don’t think I need more. Perfectly happy with this.

Did you increase voltage to 1.45v? If so, does your RAM even post with 1.5v? Mine doesn't unfortunately and I don't know why.

 

But this is very nice, especially for non Ballistix memory sticks =D rev.E rules for frequency. Maybe not for timings but for frequency its good.

 

Happy for you, you have same primaries as me =D  If i put 16 tRCD and tRP instant BSOD.. =D CL of course doesn't even train on 13. And then the tRAS is up to debate so good job!!

 

I had same like you, in the beginning my laptop could barely train the 3200. After I found the right slots it would sometimes train 3333 but not 3300 xD Funny, I actually wanted to mention to you to try to train on 133 reference clock instead of 100. And then the add odd function or whatever it was. However, now after running it for so long with this OC, it also trains 3400 for the first time pretty much always but never works after reset. I still want to look in to the command rate and if thats not possible I want to try something similar to the motherboard of my P775 like this guy did to his desktop motherboard:

No, I bought Ballistix. Same as yours.

I am selling the non-Ballistix Crucial now:-)

So have you tried my timings?

 

I can give you exactly how I have, I have computer at the moment. Of course you can keep the tRAS at 34 if you wish.

 

At the moment you and I have almost exact same timings =D I wonder if we both are limited by motherboard and not the sticks themselves.

 

Also, is it rev.E dual rank or rev.B single rank? Your new kit.

 

I think the only kit that can beat the ballistix is the Samsung B-die G-Skill 3800/4000 and Corsair 3800/4000 sticks but those are so fricking extremely rare that its almost impossible to get.

[MiRaGe]

I can’t reach some of your timings, I tried it😊

how you reach twr 11 is beyond me😄

and trfc at 475 doesn’t boot…

which program are you using to edit and save them under Windows?

 

It’s E-die dual rank

[srs2236]

These are my actual timings in the BIOS:

 

 

Actually, maybe the timing difference what you can't achieve now is purely due to the fact I have 9900KS and its a little bit better binned? (Possibly better IMC) Because I have something in my memory that I couldn't achieve the timings I have now with my old 9900K...

 

I use intel XTU but, you need to enable Realtime Memory Timing as you see in my BIOS and then more options for realtime timing changes appear in Intel XTU. If watchdog doesnt get violation with your new settings XTU will apply the setting on bootup.

[MiRaGe]

Hmm, strange…Intel XTU can’t make it well with Control Center, they interfere to each other in bad manner…

For me they don't interfere at all. I am using this version:

[MiRaGe]

Yes, I am using the same one, but once I install XTU I can’t open it nor can I make CPU adjustments in CC…very strange…

I think I remember this bug. You should try to uninstall CC, and uninstall XTU. Then install XTU and afterwards install CC. See if this helps.

 

Also make sure XTU is enabled in BIOS.

[MiRaGe]

Yes, tried this order too, didn’t help…

will try again tomorrow.

thanks!

@srs2236, can you tell me what's your TimeSpy pts with 3080 and was there big difference in FPS in games like Warzone, comparing to 2080?

And well performance the difference can be felt, but its not as big as I would like it to be. However one of the games that I could feel the most was Warzone for some reason. Maybe because of the VRAM? As that game sucks up all 16GB without hesitation.

[MiRaGe]

Can you tell me your average fps in Warzone 2.0?

I am playing with all max settings and Fidelity CAS on with ~100 FPS +-15-20.

just tryin to figure it out if it’s worth it to threw 1K€ Iut the window for 3080🤣

[MiRaGe]

Thats my best with timings, DDR4, 9900K and RTX 2080. I don't think I can do more:

 

Now the question is - is it worth it to spend 1000€ for RTX 3080...

 

Btw, why are you using RAID0, do you notice any significant improvements outside synthetic benchmarks? 
I did RAID0 on two 860 PRO SSD before and it brought nothing but more latency and more CPU workload…

Bro to be fair it definitely is not. It's not that great. Better save that money for future years to buy a BGA beast in the future.

To be honest in real world it might be even a loss and just another problem for the CPU like you say... But I have a problem with seeing bigger numbers so.. =D And it is like this - latency gets a hit but read and write speeds are definitely better than without RAID.

Is the RAID controller on P775TM‘s motherboard hardware or software?

When second, there is really absolutely zero point from RAID at all.

 

p.s. Yeah…I read it‘s software RAID…there is absolutely no point of it. At least on my previous HP 8770W there was hardware supported RAID controller…

I am going to test it myself as I manage to get second 1TB SN750 for 60€.

Yes it is software. Well, I will try to find some of my benchmark results if I can and post them here. I did lots of testing and with the right settings (also the riskiest) there is a performance improvement in *synthetic* benchmarks, about real world - I have no idea xD. Probably no improvement, I wouldn't know and honestly as long as synthetic are better i don't care =D

 

edit - found one:

 

Impossible to achieve without RAID. Same Bench results as some PCI-E 4.0 drives.

 

edit2 - found another one, it is not labeled so I am not sure if this is the correct one for the final Kingston RAID but I think so:

Can you explain exactly how did you create RAID0? Do I need reinstalling the OS or migration with Acronis would work?

did you change something in bios? Probably from ahci to rst?

You can migrate with Acronis but you will need atleast another storage medium like atleast one SATA HDD or SSD.

 

Yeah, you switch in BIOS from AHCI to RST and then create RAID0 volume in BIOS. Then just install Windows and install latest RST software. I have updated my RST modules in my BIOS to the latest revisions.

 

In my BIOS I have:

Intel-RST_EFI-RaidDriver_v18.31.3.5434

Intel-RST_RAID-ROM_v18.35.0.4635

 

These are the latest I think that you can get for P775.

 

And on Windows currently I have:

I am not sure if there are performance differences between RST versions, but sometimes some claim there are.

 

Oh, and these are my settings (fastest, but at the same time riskiest):

And yeah once you switch to RST, and go to create RAID volume all data on them are lost. So you kinda have to reinstall Windows or use Acronis and another storage medium to restore old backup.
