With the latest firmware, IDE is showing 5.3MB/s (up from 1.9MB), and bus test is showing at least 100% improvement I think too!!! Runs way way better =O
I would be interested to know (once people get onto a later firmware) what speed you get on IDE, and what card / adapter / drive you use! I suspect the CF card I am using could be better.
Sysinfo report is exactly the same. Which shows how useless sysinfo is as a metric. Sysinfo tests all run out of cache.ekalkici wrote: 27 Jun 2021 09:03 Alson can i ask how many mips on sysinfo you get with new firmware @ 62.5mhz . With standart old one i get 48.75 mips. Just a refernace test.
In your case, this is probably a CPLD issue. I've seen a few 10ns cplds that won't go past 62mhz. Replacing the RAM cpld would normally fix this.GadgetUK164 wrote: 01 Jul 2021 20:15 Out of interest, can you think of a scenario where the lack of timing fixes could stop a CPU running beyond 62.5Mhz? I've just ordered ANOTHER 75Mhz chip - this time from Russia. The RC75 I got today again wont go past 62.5Mhz =/ It's a super lottery trying to find an LC or EC chip that will go beyond 62.5Mhz. That will be chip number 4... I will sell a couple of them and keep one for the TF360 if that has a run at some point.
Do you have no chance on 75 mhz or work a bit then crash when load or etc. I tried with different motherboards and timing fixes , results were same. My card work a bit stable at 75 mhz with rev5 then crashes. Maybe with new firmware can be stable @ 75 mhz.GadgetUK164 wrote: 01 Jul 2021 20:15 Out of interest, can you think of a scenario where the lack of timing fixes could stop a CPU running beyond 62.5Mhz?

Sorry, I didn't see that previously! I assumed it was just the CPUs I am trying (and I suspect it is tbh - they are all rev 4's). Also, others are running much faster already so this led me to think it was either the CPUs or my 1200 (regards timing fixes).terriblefire wrote: 02 Jul 2021 10:22 I think i've said this 100 times now..
The firmware needs an update to get more speed.I need to make wholesale changes and i've not had time.
Dont waste your time and money on this until i've got this sorted. I just need to sort my basement damp out first.
Thanks! I wasn't aware that different speed CPLDs might be needed - I will hang fire until Stephen has time to work through tweaks etc. Not in a rush - can see if that other 75Mhz (looks like R5) makes a difference when that arrives.alenppc wrote: 01 Jul 2021 21:53In your case, this is probably a CPLD issue.

Nah, all three just freeze the system straight after selecting 75Mhz - pretty sure its due to them all being rev 4 CPUs though tbh!ekalkici wrote: 02 Jul 2021 08:42Do you have no chance on 75 mhz or work a bit then crash when load or etc. I tried with different motherboards and timing fixes , results were same.

My CPLD's are 10ns. And have heatsinks on both CPLS and 060. Fan cooling from right side.
