Ballistix Sport LT Overclocking

AndreiD · 23 Oct 2019 at 03:43

Did some testing to CLDO_VDDP, doesn't seem to do anything if I set it higher than 0.9v at 3600Mhz and according to the Stilt raising it is only useful if going for clocks higher than 3600Mhz on the memory.
So if going for 3733Mhz raise it to 1v, if not just leave it auto (0.9v).
VDDG can probably be left on 0.95v/auto for 1800Mhz Fabric Clock, albeit setting it to 1~1.05v probably won't hurt and is needed for higher clocks.

Edit: Did some VDDG testing too, 0.95v to 1.05v had no effect on stability with the Fabric at 1800Mhz, but it had a very minor effect on memory read/copy of <1% (~51400MB/s read/~52000MB/s copy with 0.95v vs ~51900MB/s read/~52300MB/s copy with 1.05v). Might as well do 1.05v VDDG since I didn't notice any drawbacks other than losing minor power savings.

My X570 Elite with 75E sticks booted perfectly but errors at 3600, I used the settings that Tamzzy listed with 'profit' at the end. Is it worth tweaking the timings and having another go?

Vtt is also called voltage termination

Yeah
Pretty easy overclocking

So left everything on auto but changed tRC to 58 (is that too low without tweaking else where?), is there any reason to change anything else, left cLDO_VDDG and cLDO_VDDP on auto, heard they suppose to be 0.9 and 0.95 on auto but they higher than that on ryzen master.

Cheers

Possibly yes, When I left everything else on auto, Ryzen master had VDDG really high, Higher than SOC voltages which it isn't meant to be.

Maybe set VDDG and VDDP to 0.9 and 0.95

From what I've read, VDDG can be 0.040v below SOC. Try it at 0.9 and see how it goes.

ok cheers, got it at 0.95 and VDDP at 9.0. This is what dram calculator recommends.

I'd probably tweak the voltages tbh.
Are you at xmp settings?
Try trcdrd set at 22

Thanks for the reply buddy. I'm using XMP settings, which voltages should I give a tweak? I'll try trcdrd too thanks!

MegaPinches · 23 Oct 2019 at 11:13

On CPUz I have only a tRCD value which is 18, in my Bios I have tRCDRD and tRCDWR (both 18), which one would be the tRCD corresponding to the value on CPUz? (I know I can test and find out but engaged in a memtest)

Thanks

Just make sure that the sticks are not DOA by running memtest first at stock and making sure there are no errors.
Gigabyte motherboards don't adjust the dram voltage termination properly. So need to set manually to 0.7 (personally I use 0.705)
Vsoc 1.1v
Can try vddp and vddg 1050mv, but as you've read this far, lots of variability in vddp and vddg voltages so you might have drawn the unlucky straw and need to slightly play with those voltages

It would report the highest number

I recall seeing that the most important secondary/tertiary timings for best gains for ryzen are when trc, tfaw, trcp, trdrdscl and twrwrscl are tuned.

Ta, thanks for the spoon feeding, finding my way around it all now. Cheers

Thanks both! Have upped the Voltage Termination slightly, and gone with AndreiDs timings, currently 15mins into Memtest without an error.. previously it errored within seconds.

Leave memtest running overnight just to make sure.

I'm using the windows one bundled with Dram calculator, I open up 6 instances using 2048 to 3072mb on each and leave about 500mb spare, is this the way to do it or should you completely max out the capacity?
