New to overclocking; need some help

post #1 of 20
Thread Starter 
Hey guys, I'm new around here and am need of a little help. Before I get started though, I'll list some of my hardware (what I believe to be relevant):

Motherboard: EVGA nForce 730a (113-M2-e113)
Processor: AMD Athlon 64 X2 7750 Kuma 2.7GHz Black Edition
Memory: (2) OCZ DDR2 PC2-6400 2gb; (1) Wintec AmpX 1GB DDR2-800 PC2-6400

So anyways, like i said, i'm pretty new to all of this and ive been going through several tutorials, focusing mainly on the "Offical" Overclocking Guide - AMD Socket AM2 by durch. Right now, I'm at the point where I'm perusing through the bios trying to identify all of the necessary and relevant settings that pertain to OCing (section 2 in durch's tutorial). However, I can't seem to find the setting(s) for either of the multipliers: HT or CPU. I've dug through every menu and submenu, but still nothing. I even tried flashing my bios with the newest version from EVGA's website, thinking that this might give me some more options within the bios. This notion was based on this from EVGA's updated driver page:
"The following was updated in release Z13 (my bios update):
Adds support for Phenom II CPU's
Improved support for CPU Multiplier adjustments."
Unfortunately, I still could't find this setting in my bios following the flash. My bios is Phoenix - AwardBios CMOS Setup utility, if that means anything to anybody. Right now, the processor is running at 2700 with 13.5 multiplier (stock). This I know from the boot up screen. But how the hell do i got about changing this???
Also, if anyone has any advice on a good place to start for overclocking to something reasonable and fairly conservative--say, 3000 mhz or so--it would be really appreciated!

Also, I've got some screen shots; maybe that'll help:

The last screen is the important one, but some things are labeled weird so I understand your confusion.
CPU Frequency is your FSB, but where is your multiplier?

I know! I've read somewhere that K8 <-> NB HT Speed/Width somehow correspond to all of this but i'm not sure how. Perhaps my multiplier options are hidden within there? When I look at the options for the K8 <-> NB HT Speed setting, it shows me options for setting it at 200 mhz through 2.6 ghz with 200 mhz increments (200, 400, 600, 800, etc.).
The K8 <-> NB HT Width options are: (down arrow) 8 (up arrow) 8, (down) 16 (up) 16, or auto. Right now both speed and width are set to auto. Also, while poking around in there again, i figured it might be beneficial to put up another screen shot or two. These are for the sub-sub menus: CPU feature and DRAM configuration found within the Frequency/Voltage control submenu . I'll be editing my original post and tossing them up there. Maybe those will help out.

Keep your NB HT as close to 2Ghz as possible and keep the width set to auto.
Have you done a search for overclocking on your mobo?

You can overclock without the multiplier, just start bumping up the FSB, remember changing the fsb will also change your memory clock, NB, HT, and of course your cpu clock. Just keep an eye on your ram and keep it around 1333 (even if its stock at 1600 or more, PIIs don't benefit form the added bandwidth but they love tighter timings wink.gif). HT should always be arounfd 2000 and your NB should be as high as you can get it stable.. you may need to bump up the NB voltage to 1.3-1.35v with a decent fsb overclock.
Once you start becoming unstable after continually bumping up the fsb, just add more voltage to the cpu in 0.225 increments or whatever the smallest is that your mobo allows. This Will add heat so make sure you're keeping an eye on them... full oad try not to break 65 degrees and the max voltage I would use is on a PII is 1.6 but lots of people say 1.55.
Let me know how it goes.

Ok, so keep in mind that I'm quite new to this, so bear with me here with these questions redface.gif

Are you referring to the "K8 <-> NB HT Speed" that should be at 2ghz? And what is this setting exactly: NB or HT... can it be both? Based on everything that I've read and what you've told me so far, my guess is that "CPU-NB FID" (screen shot 6) is the setting for NB frequency (it uses a HEX value for which I've found a chart) and that this "K8 <-> NB HT Speed" is my HT frequency-- what do you think?

to be clear, are you referring to the CPU frequency here (screen shot 5: frequency/voltage control) by "FSB"? And what sort of increments would you suggest? Also should this be done in conjunction with changing the "NB HT" to ~2000? That is to say, should I just go ahead and set the NB to 2000 right off the bat, see if its stable and then start moving the FSB up incrementally, or should I do both simultaneously, bumping both up a bit at a time?

So, how exactly do I keep my ram at a defined value? And what does 1333 and 1600 refer to? Also, what do you mean by tighter timings? My guess is like 5-5-5-15-20-2T (me and "looser") vs. 4-4-4-12-24-2T ("tighter"). Can I change these settings, and what benefits/risks are involved?

I'm assuming that PII refers to PC2 Ram, no? If it does, then all three of my ram sticks are meant to be run at 1.8V, but the Wintec (1024) can go up to 1.9 and the OCZ's are 2.1 EVP (meaning they can go up to 2.1V). Or am i misinterpreting PII?

Thank you so much for your help thus far and please forgive my newb-ness!biggrin.gif

K8 = your cpu
NB = North bridge
HT = Hyper transport

"K8 <-> NB HT Speed" this can be looked at as two parts "K8 <-> NB" and "HT Speed". The first is like a diagram showing you what the HT is.. a link between your NB and you CPU. So this is you HT speed only and yes, keep it close to 2ghz

Yep, CPU frequency however it's obviously not your actual CPU frequency it's the front side bus which is then multiplied by (you guessed it) the multiplier to give you your actual cpu clock. If your FSB is 200 and your multiplier is at 15x then your CPU clock would be 3ghz.
I'd bump your fsb up by 6 or 7 each time depending on your multi.
Your HT, memory, cpu, and NB all have a multiplier. If you change the FSB you're also changing all of those things I just listed. So if you want to keep you memory around 1333 and you bump up you fsb you'll eventually have to drop your memory multiplier down a notch. This is the same for all of those things... You have to keep an eye on everything.. this is why having an unlocked cpu multiplier is good because you can overclock your cpu with changing anything else.
Try to get you NB as high as possible, you may have to give it some voltage to keep it stable tho. Like I said 1.3v to 1.35v max. The NB is reliant on your FSB so you just have to bump up the fsb to see a change in your NB.

I have ram that is stock at 1600mhz but I underclocked them to 1290 (closest I could get to 1333 due to multi and fsb combination). This allowed me to set tighter timings, timings are just another thing you can tweak to get more performance out of your system. The lower they are, the better. No risks other than stability issues like most things, if it becomes unstable just give it more voltage or increase the timing.
There are lots of guides on ocn for this but if you need specific help let me know.

PII = Phenom II

No Problem, I remember when I was a noob lol. If you're not following me completely just play around with stuff and you'll get an idea about how different things are effected by the fsb.

Ok, I think this is all beginning to make a bit more sense now. So here's the thing: I've been able to locate the CPU multiplier (CPU FID) and the NB multiplier (CPU NB FID) but I'm not seeing a multi for the HT link. Like i said earlier the "K8 <-> NB HT Speed"--which, I'm understanding to be the "HT link" setting--gives me the option of 200 mhz through 2.6 ghz with 200 mhz increments (200, 400, 600, 800, etc.) So could it be that rather than having an HT link that's reliant on the FSB and its own HT Link multiplier, my system allows me to set the HT Link independently? After all, there doesn't appear to be a HT Link multiplier...

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... only the cpu multi is shown directly.

oh, ok.. well see now i'm a little confused again redface.gif. 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)?

Really? I've had mine manually set to 1600. =(
