AMD Athlon X2 7750 BE OC Club - Page 112

post #1111 of 1165
Quote:
The VID is the "stock" vCore for each chip, and it varies from chip to chip of course. The VID tells the motherboard: "This is the voltage I require at stock speeds when the VCore setting is on 'Auto' for proper operation." That's it.
Your "Cpu Voltage" is what your cpu is currently being fed.
Ok, so i've read and reread this and I'm still not entirely following.
This is what I have found with a little experimentation though: both CPU VID and CPU Voltage seem to have an effect on the vCore. The problem though is that I'm not sure how much of an effect each actually has respectively.

Setting the "CPU Voltage" to 1.6 results in a vCore of 1.4 in the BIOS, but Core Temp--the only monitoring program that I've found which doesn't give me a reading of .976--will continue to show 1.325 if I've left the CPU VID @ stock..
On the other hand, changing CPU VID impacts both vCore in the BIOS and in Core Temp readings. What's strange is that I get two different readings in BIOS and Core Temp, with core temp's always being lower, but never a constant value lower. For instance, stock CPU VID will give a vCore of 1.36 in BIOS and 1.325 in CoreTemp (difference=0.035) and another CPU VID value will give a BIOS reading of 1.39 and CoreTemp of 1.3625 (difference=.0275)...

Also odd, is that CPU VID's values seem to have an inverse effect on vCore. CPU VID is in hexademical, so when I input lower hex values, I end up with higher vCores. With vCore, I can at least check the resulting values from changing CPU VID in my BIOS/Core Temp so I can see whether there's been a positive or negative effect.

This leads to a bit of uncertainty in another area. See, my NB VID, NB FID and CPU FID are all also in hexadecimal, but for these settings I can't see the resulting values from my manipulations--at least, i don't know where to look for them. Therefore, I have no idea whether these other options are likewise inverse like CPU VID appears to be, or if they aren't...

Oh and by the way, my mobo, which i've added, is a EVGA nForce 730a, which i'm getting increasingly more frustrated with... well, that and my bios.

Yeah everything in hex is.. yeah weird. Looking at the manual for your board, when you go to the cpu/voltage control section in your bios, instead of going to "Cpu Feature" I noticed underneath "K8<->NB HT Width" is "Cpu Voltage." Are you able to take it off of "Auto" and muck with it at all? Or is that in Hex as well? If that's a new option, perhaps it's your "golden ticket" so to speak.
I've never seen Hexadecimal used that way in any board to my recollection, it's pretty strange. So I can't quite comment on it as I've obviously never encountered it lol, but seems somewhat odd for sure.

So that's what i'm saying: i have been changing the "cpu voltage" option--not in hex(!) btw--so far trying Auto, 1.55V, 1.575V, and 1.6V. As you can see, the settings for this option begin at 1.55 and increase by .025 up through 2.8ish or so. Right now, since i haven't been able to figure out what the exact effects of CPU VID vs CPU voltage are, I've been toying with various combos of the two, noting the differences in core temperatures (lows and high) and readings in the BIOS vs. Core Temp (the program). I'm hoping to discover something about how each effects the system.. or at least the variables i just mentioned.

yeah yeah, saw cpu voltage in a few options, confused the mess out of me. Lol you've got a bit more patience than I would with that board. Hopefully at some point you've got it all down packed and write out some sort of walkthrough or guide to ease it up for others that own it lol. I will say that my 3.5ghz OC was done at 1.5v Not sure how safe 1.575+ will be with your cooling. But if you can get a way worked out to stay right at 1.5 or just above, you'll knock down the wall that keeps a lot of these chips from going past 3.1ghz stable

haha, I'm not sure if its patient or if its just broke. either way, same effect, right?

So far, i haven't actually managed to raised my vcore past 1.4. and temps have been pretty decent (i think) at between 27 and 35. The strange thing with my BIOS settings is that even though I'll set CPU Voltage to 1.6, it only registers as 1.4 in the BIOS upon the next restart. I haven't actually tried more than 1.6 at this point; i'm still experimenting with different combos and i'm also waiting to hear back from some other users from different threads before I decide to do anything else drastic.
