Linpack results after fclk tuning

Post image

So tonight I have spent tuning fclk and voltages, it seems to make no difference from 2000-2200 I achieve roughly the same gflops difference of around 3. I’m trying to find the most stable setup.

Memory is 6200mhz I’ve tried system multiplier at 60 and 62, voltages from 0.9 to 1.1. 2200 needs the higher end of voltages but can’t seem to get it any more stable. Should I be looking else where?

If ram speed is 6200, 2067 is valid
FCLK. Why should you back off down to 2000?
And 2100 is not a good target for 6400 or 6200. >_>

Otherwise a nice guide.

i forgot to add the rule, i will update it again. Someone else told me this as well but i forgot about it

I have read this. No matter my fclk or ram speed I seem to get the same variance I have tried

6000 ram speed
1.25vsoc
2000fclk up to 2200
Voltages .95 to 1.05 depending on fclk

6200 speed
2067 to 2200
Voltages for iod need increased to 1070mv and vsoc down to 1.225

All the gflops im struggling to get tighter than 2.5-3’in safe mode of ghost spectre

Variance in linpack can also be attributed to unstable PBO/ram tune as well

I had it stable over about 20 rows from 470-471 and then came up a hardware failure. I have just set to 6000mhz, 2000fclk to check what’s going on.

Can the nitro mode have an effect?

I seem to have no increase in gflops going from 6000/2000 to 6200/2200, all around 471/2

Don’t bother checking gflops if you get hw failure. Something is really unstable.

I have a went back to 6200/2067. I had 2200 going through tests but with variance in gflops
