TerraRaptor Posted February 15, 2021 Posted February 15, 2021 Seriously, 4 DIMMs and 317mhz is pretty nice even for 939:) Quote
digitalbath Posted February 15, 2021 Posted February 15, 2021 (edited) Thanks guys! I have to apologize myself here. I suspect that this result is incorrect and that CPUZ is showing incorrect values here. I will delete this result, just in case this result is incorrect. I don't want to cheat. The story behind it is that I found out where the FSB: DIMM divider is in the PCI register. So I was able to boot normally with the divider 1: 1 and change the divider from 1:1 to 5:6 in Windows. The system is measurably slower after that, so I thought that the divider would also be set correctly. It does not seem so (after further tests). The FSB: DIMM divider is in 7Ch (b0d0f3). Sorry. @TerraRaptor No, this version of cpuz is wrong here. Version 1.58 shows up 2 dimms correct, but I wasn't able to validate with this version. edit: can a mod delete this result?

I.nfraR.ed Posted July 23, 2021 Posted July 23, 2021 (edited) I have encountered the same thing while developing the nf2 tweaker. When booted with 1:1 you can then "set" any FSB:DRAM ratio and cpuz is easily fooled, because it seems to read that register. https://valid.x86.fr/zukryk I've obviously exaggerated "a bit" with the 3508MHz (DDR-7016). 1:15 is the highest possible. CBID tool is reading DRAM frequency correctly, so I'm trying to find how to reproduce it and report to Franck. Makes me question the validity of the current top-1 valid for socket A (except that one of from @digitalbath). Not calling anyone cheater, but it might be another honest mistake. The thing is we were all stuck at 300.7 max, while the Greeks managed higher. Not saying it's impossible though. Edited July 23, 2021 by I.nfraR.ed 1 Quote

That would be great. There are another mistakes in CPU-Z: Sometimes cpu-z detects twice the number of dimms. When using only one dimm in ASRock K7NF2, CPU-Z detect most CL2,0, not CL2,5 or CL3,0. see here: https://valid.x86.fr/xexj6t I guess that are minor Problems. Cheating FSB:DIMM ratio is more crucial. 2 hours ago, I.nfraR.ed said: Makes me question the validity of the current top-1 valid for socket A (except that one of from @digitalbath).

Thanks for remembering this. I forgot to ask for deleting this result. Even this 300.7 is hard to achieve. I hope, I will pass (sometime) the 300MHz limit with S462 and without cheating. ------ What also makes me think: some BIOSes use 6:6 ratio register, and some use 4:4 (DFI). Is there a difference? Both are 1:1 FSB:DIMM ratio. Edited July 23, 2021 by digitalbath Quote

My examples: AN7 clocks better on a 6:6 ratio NF7 clocks better on a 5:5 ratio All my DFI's seem to clock better at 1:1 300.7 was tough to get, but I highly doubt Stelios tried to beat the system, if you will. It not his way. Edited July 23, 2021 by Mr.Scott 2 Quote

Maybe I can find a proper ratio for my boards. 1 Quote

Just make a report and write to Franck, he does respond quickly most of the time. Quote

Good Idea. Worth to check this. 15 hours ago, Antinomy said: Just make a report and write to Franck, he does respond quickly most of the time. I will do that after my mod BIOS for my ASRock board.

Seriously? That's the one thing i never tried in all those years... I usually just kept what the board used as default for synced FSB:Dram. Might be interesting to dump the chipset registers and to see if there are differences. 1 Quote
