If the ram, nb and ht link are all set up this way where you're inputing the final resulting speed, then how does FSB/cpu frequency factor into it? I guess what I'm asking is if you take the equation: HT Link=FSB*HT multiplier, where the two variables-- HT Link (being whatever you set it to in the bios) and FSB (also whatever its been set to in the bios; 200, in my case).

To pose this question in another manner, if I was to set "K8 <-> NB HT Speed" to 2 ghz and then adjust my FSB to 250 (with my HT multiplier appearing to be at 9 by default), would the HT Link speed remain at 2ghz or would it rise to 2,250 (9*250)?

Your HT would rise to 2250. The FSB factors in because your multiplier on the NB, HT, and ram cannot be changed. This means You need to increase you FSB if you want a higher NB, HT, or ram speed. You can't just make your own multiplier like you can for your unlocked cpu.

To OP: I have the same problem as yours... Was the utility "Frequency/Voltage control there before you flashed? Mine is not there, and i have the phoenix awardbios v6.00

yeah, mine has always been there (both before and after the flash). I would suggest going to your mobo's website and looking for a newer bios update for your system. Be weary, this is an annoying process if you don't have a floppy (does anyone have a floppy anymore??) or blank cds. I was going to try a "flash from a thumb drive" method until i just decided that too much was on the line and went out and borrowed some blank cds.

Ok, so I'm still confused by this, but i think I've pegged down the specific source of this confusion now: So here's my (hopefully) final question on the matter--I know, this is probably getting somewhat annoying to you, but I really do appreciate your patience:

So, I guess I'm just hung up right now on what the heck the deal is with this multiplier setting (and by extension those of NB, HT, and RAM).

On the one hand you said of "K8 <-> NB HT Speed":
Quote:
This is the multiplier, it's just showing you the resulting speed. Your ram and nb will be the same, they'll show the resulting speed...
but now it seems like you just told me that the "K8 <-> NB HT Speed" setting doesn't really show you the resulting speed because whatever you set it to is simply overridden by FSB and the HT multiplier. Again, I know you referred to it as the multiplier but i can't make sense of that either, really. If it were the multiplier, then the values in the options for that setting should change depending on what the FSB is set to. For instance: if FSB=223 for argument's sake, then the values in the bios for K8 <-> NB HT Speed should be 2453 (for 11x), 2564.5 (for 11.5), 2676 (for 12x) and so on so forth. But they don't, the values are constants (200-2.6ghz in 200 intervals).

To me, this would all make sense if the "K8 <-> NB HT Speed" (HT multi) actually gave you options for 1x, 2x, 3x, etc, but as we know this is not how it appears in the BIOS. So then i basically can't see how this isn't a redundant setting. Its stuck on 9x (can't change this, right?) and therefore, regardless of what you set it to, the actual resulting value is simply 9 x FSB!?!

haha, oh boy..

Well it just shows you what the speed would be based on your current fsb.. change your fsb and then go check the options for your NB, HT, and ram speed, they should have changed. This is normally the order in which people go about selecting clocks (FSB then HT, NB, and memory). Just Showing 1x, 2x, 3x, etc would just making things a little more difficult because you'd have to do some math to know wither the OC is reasonable, just like what you have to do for your cpu which is kinda annoying.

I think this is the source of your confusion! You CAN change the multi. When you're overclock your cpu via the fsb you will usually have to drop the multiplier down on your ram and HT to keep things running smooth and stable.
For example: If I set my ram at 1600 when my fsb was at 200 then I oc'd the fsb to 245 my cpu would jump to 3.55ghz but my ram would be at an unstable speed of 18xxmhz so before I booted up with the OC for the first time, I would have to drop the speed on my ram.. essentially selecting a lower ram multiplier.

ah ha! Ok, I believe that you have set me free from my confusion! Thank you, sir!

Hey so here's another question: is it really possible that my vCore is at .976??



the funny thing is, speed fan is saying the same thing.

core temp on the other hand is reading 1.325 (which is what I've manually set my CPU VID to), but It's not showing any fluctuations between full loads and idle, so this leads me to believe that its not quite accurate either. And for the record, CPU-Z shows a fluctuation not up, but down during full load to .968. But this value goes back and forth to .976.

Hmm that's really strange. I don't have any experience with this particular processor but I've never seen voltage so low for that kind of clock speed. Another thing is I've never seen that large of a vdroop (setting it in the bios only to have it become much lower after booting to the OS) from a motherboard before. However, it is normal that your voltage drops a bit at load so this makes me believe that it could be accurate..
I suggest making a new thread for this issue to see if you can find someone with some experience with your board or processor.

Thanks Phoriver. I've actually started a new thread in the EVGA forum regarding this. I'm hoping to get a tech/moderator to help me out.. though, i'm not going to really hold my breath on this. I think i'll probably just resort to experimentation until i'm finally fed up and simply buy a new board/cpu. we'll see. thanks for all your help again, though.

No problem, let me know know what they say. (if they say anything at all :\\).
