Sisoft Sandra, CPU-Z and AIDA gives different info - what should I trust?

Hi,
I have a P4 2.8C at 243MHz FSB(3.4GHz) on ABIT IS7-E with 2x512MB Kingston BH-5 memory. It's been a while since my last reboot but I *think* I set my FSB/DRAM ratio at 5:4. However, CPU-Z and Sisoft both show my memory running at 243MHz at a ratio of 1:1. AIDA however tells me that my memory is running at 194MHz, which would be the case if my memory serves me correctly. I know I can probably just reboot and verify the settings, but I'm wondering why they would report it differently? Has it anything to do with the GAT settings that I've enabled?
 
Personally, I trust CPU-Z alot more than other software diagnostic proggies, but they are all known to make mistakes. BTW, weren't you aware that computers need to be rebooted fairly often?😀
 
Hehe, I just got the system and I'm priming it for stability, which explains why I haven't rebooted for 1-2 days yet 🙂

It's kinda tough to trust any one of them since they're showing different values.
 
Hmmn, turns out CPU-Z and Sisoft Sandra are wrong. I rebooted and saw that the ratio is set to neither 1:1 nor 5:4, but the other setting(Auto I think). Then I switched it to 5:4, booted up, and CPU-Z still shows a ratio of 1:1...what's up with that? A bug?

I use AIDA32 a lot also. I think Thugs popped it onto here as a possible memory test suite and i picked it up from there. (could have been PiFast though)
 
Thanks for sparking my memory Elcs, it was Thugs and he was proposing it as a substitute for SiSoft's poor memory bandwidth tests.

:beer: for you!
 
Well I'm glad I triple-checked then. I was skeptical with CPU-Z at first, then I checked it again with Sandra and it showed me the same thing.
