Okay, so one test after each update. Every benchmark (Aida, 3DMark, Geekbench etc.) fluctuates by some amount between runs, so you should run the benchmark at least three times for each BIOS version to get some idea on how much the results differ between each run. You should also probably wait some time before running the benchmark after booting up, since there can be all sorts of stuff going on in the background even after you have access to your desktop.

Also, I didn't say the differences in speeds are marginal, but they may be explained by other things than the BIOS. The latency differences on the other hand look marginal, but you won't know for sure until you do several runs with the same exact setup. For example, back when I was experimenting with RAM timings, the L3 cache results could vary quite a bit (over 20% for transfer rates and even jumps from 12.2ns to 20ns for the latency).

I'm not on my personal computer right now, but I'll see if I can post some of my AIDA results later today, just to show more accurately what I mean. The results of course only apply to my system, but they might illustrate my point better.

Hmm. Interesting. I'll have to test that scenario on my system, since I haven't noticed any major issues in PUBG. These are the averages of five AIDA benchmark runs I've done on my current setup:

Memory Read: 46849.6 MB/s
Memory Write: 45354.4 MB/s
Memory Copy: 40837.8 MB/s
Memory Latency: 77.48 ns

L1 Cache Read: 459.156 GB/s
L1 Cache Write: 230.184 GB/s
L1 Cache Copy: 459.12 GB/s
L1 Cache Latency: 1.1 ns

L2 Cache Read: 433.8 GB/s
L2 Cache Write: 225.972 GB/s
L2 Cache Copy: 388.276 GB/s
L2 Cache Latency: 4.7 ns

L3 Cache Read: 306.972 GB/s
L3 Cache Write: 218.552 GB/s
L3 Cache Copy: 292.34 GB/s
L3 Cache Latency: 12.2 ns

Just based on these numbers, I should be experiencing similar or worse performance issues. It may be that I'm just not paying attention to occasional stutters or that I've just never used the map while looking through a scope. I'll take your word for the change in performance and transfer rate numbers, but the whole thing just seems odd and it would be interesting to know what the root cause is.

i'm not impressed by this bios, ram stability seems even worse than before. with this update 3200mhz is pretty unstable on my gflaresX.

@Handrox, reading on the forum link you've given to us. It seems your the only one who is complaining the latest BIOS.
