Very odd memory divider / bios problem?
I am using a DFI Lanparty SLI-D motherboard and an AMD Opteron 146 CPU that can do 3Ghz on air. I don't want to overclock my RAM at all and my CPU is multiplier locked upwards. So what do I do? Use a memory divider.
So I set my divider to the lowest setting it will go, 100 1:2, to ensure the memory is kept at a safe operating frequency.
Here are the exact bios settings I am using:
HT/FSB Freq: 300
CPU Multi: x10
HT Multi: x3
Mem divider: 100 1:2
vCore 1.55
So why am I confused?
When I turn on the computer the bios reports the overall memory frequency to be DDR200 – very much below what my memory can do. MEMTEST and Windows, however, report the memory frequency to be 150 (DDR300).
Which part of my computer is telling me the truth? I am most confused. The computer loads XP but it isn’t entirely stable yet, possibly because my memory is underclocked far too much? Or I need more volts on the CPU… but it has run fine on 1.55v in another system
Before I continue, I know that you can’t take one component from a PC and expect it to perform in exactly the same way in another system. I am well aware that I possibly have a lot of tweaking ahead of me. However, I am convinced something isn’t quite right.
None of the other dividers available to me allow my PC to boot past the HDD detection screen. I have tried two different bioses but they seemed to break all of the dividers, none worked! So I reverted back to the original bios and the 100 1:2 divider is working again. Well, it will load XP at least! This might indicate that the BIOS is the key. Perhaps there is one out there which is more compatible with my RAM and will allow more dividers to work?
I am using 2Gb G.Skill ZX Series DDR PC3200 (DDR400) 2-3-2-5 memory in the slots recommended in the guide.
Any ideas? Or have I just completely screwed something up?
Thanks for reading!
