kberguy1, thanks I'm not so sure I'm going to apply TIM to the PWM though, seeing as AS-5 is conductive o.O

Anyway, what exactly does the PLL voltage do? I'm trying to get my proc stable at 430x9 and I've raised voltage two or three notches from 423x9 stable. Does it make sense to stop bothering with the vcore and start raising NB,SB,PLL or clockgen voltage instead? Which is most likely to cause unstable OC? And also, what's GTL reference clock? I have mine set to 110/114/117 (I think), as per the Anandtech reviewer's OC.. could it be too high for a 423x9?

Level off GTL 1/3 ....0/2

[2000army]

Do you think a evercool chipset cooler would fit on the southbridge?

[C-N]

What GTL reference clock? I have mine set to 110/114/117 (I think), as per the Anandtech reviewer's OC.. could it be too high for a 423x9?

Upping SB/CPU PLL and clockgen voltage seems to have made it stable..

I've studied electrical theory.. but never quite got the hang of it :p Do I have to readjust GTL ref everytime I change VTT or NB voltage?

as5 is mildly capacitive, not conductive at all.use ceramique if that worries you but im sure it wont cause any damage.

Upping SB/CPU PLL and clockgen voltage seems to have made it stable..

Need to be careful with CPU PLL voltage. Intel specifies a maximum of 1.55 volts. Excessive PLL voltage can degrade the max FSB of the processor. I have no figures of what would be allowable for 24/7 use but I would not use more then 1.75 volts as that may even be to much. I do know from personal experience that continued use of an elevated PLL voltage above 1.75 volts will lower the max FSB of the processor.

Would depend on how close to optimal the GTL voltages were at the previous settings and how much headroom is left in the components for an even further overclock.

The GTL voltages are derived from VTT. Also, the values of GTL in the BIOS are not a set parameter. You can see this looking at one of the VTT/GTL tables. Picking some arbitrary values will show this. If at a VTT voltage of 1.20 the setting in the BIOS of 80/80/80 results in a reference voltage of 67% of VTT raising VTT to 1.28 may result in some other percentage.

So if a person's previous settings resulted in an optimal setpoint for GTL raising VTT will require an adjustment of GTL to bring them back to the optimal value.

Increasing the other voltages in the BIOS alters the impedance of the circuits, increases noise levels and temperatures. All of these change what the optimal value of GTL may be.

Heh, I lowered the PLL voltage back to 1.55 and it crashed within minutes, just as I was typing a reply here in fact.. So I've jacked it back up to 1.75v.. Is the PLL chip the one on the motherboard that SetFSB asks you to identify, or a chip on the processor?

And one more thing, would lowering the PLL and jacking up the vcore produce the same result? Can either compensate for another? I'd try but I don't have water cooling and it's already touching 70deg on the warmest core folding..

[howard]

I am going to have a closer look at this myself over the next day or so. I just picked up a Thermalright HR-03 R600 VGA cooler for my ATI HD2900XT card, and need to mount it first to see what clearance issues it might create. I have a Swiftech MCX159 HSF and a Noctua NC-U6 HS in my "spares" bin, so I can trial fit them both. I will see what works best, and can give you all my impressions by about this time tomorrow.

Cool! I can't wait to hear how it went. Unlike you I break hardware just by looking at it. I have the Noctua (is that a pretty chipset cooler or what? It's almost a shame to put it in a closed case) on a 680i board I'll swap if it works out better on this LP.

Edit: Great, I'll try the Noctua. I haven't had as good results with the Transpiper as you've had going by the SG PWM measurement and after sacrificing an entire tube of MX-2 (note to self: Use ceramique for filling the holes in the Transpiper clamps). That 90 degree heatpipe? I have a feeling mine is broken at the bend, it doesn't get warm beyond the bend.

I wonder if I can still get something out of the Transpiper by sticking one end of the "fork" into the PWM slot and bypassing the ell pipe and extra clamp

[howard]

Can someone help, can you fit Thermalright Ultra120 eX. on this mobo in an Antec 900 case? Will it fit?

Yes, mounted lengthwise as mentioned earlier. Note though you won't be able to mount a 120mm fan on the side panel but this shouldn't inhibit you from trying it: The ventilation in this case is awesome, and an 80mm will work secured sort of sideways over the hole.

The Phase Lock Loop circuitry is part of the processor. The digital and analog supply voltages for the circuit are supplied from the board.

And one more thing, would lowering the PLL and jacking up the vcore produce the same result? Can either compensate for another? I'd try but I don't have water cooling and it's already touching 70deg on the warmest core folding..

Normally increasing the PLL voltage only helps with the CPU FSB wall. Who knows why. Possibly an apparent reduction in jitter by increasing the voltage? But anyway what you will usually see is once PLL needs to be increased the processor has pretty much reached the end of the road as to much more of an increase of FSB can be tolerated.

[Brother Esau]

I already told you ...You need to adjust you're CPU VTT GTL if those values are incorrect then you will crash within minutes maybe longer but they need to be adjusted properly and that takes allot of work and hair pulling

As Praz said don't put more than 1.75 CPU/SB PLL voltage................

[x6700]

I've tried BIOS 0808 & 0815, after flashing I've got trouble booting up for 1st time.
Always stuck at C1 error.
I should boot with 1 stick of RAM to success.
Anyone has the same problem ?

Also I think 0808 is better than 0815.
Trying BIOS 0810 now.

I have the same problem as you. I can't do anything with 3-4 sticks of ram after the flash. My computer only works with 1-2 sticks.

[Brother Esau]

did you buy a bios chip I cant remember?

I just meant that you apply a thin film of AS-5 or similar thermal paste to the area of the PWM heatsink where the copper plate mounts to improve heat transfer.

You can still make a push-pull combination, yes?

[cowie]

I still have some Bios Chips left if anybody would like to buy a Back up Pre Programmed Bios chip for this board!

love this mb but.....darn c1 sucks.

Sent PM to you

Alright folks, having a very frustrating problem.

The PC right now:
E6600
6200 LE
2X512MB Crucial Ram

Don't ask why, but my other stuff is not in right now.

Any way this is the problem.

I installed windows, I boot in, pop in the LP disc, install the network drivers, chipset drivers, and Smart guardian.

I restart, and I figure it should detect my internet through the cable, but it dose not. I usually had no problems on my other board, by just popping it in and have it be detected. So I go into Network Connections and it's blank. Completely blank. I have tried both ports, and both light up when the lan cable is plugged in.


Any ideas?

EZClear is your friend it works 99.5% of the time for me but you must follow the procedure properly or it wont work.

Browse your CD & install the teaming app too or it wont work.

[patrickadizzle]

Interesting.

That did work C-N, but I still have no icons at all, but can connect to the internet.

I'm pretty sure this is a windows problem, relating to a missing .dll

I'll search round.

[Brother Esau]

Sounds like reinstall time to me!

[Brother Esau]

Out of curiosity has anyone been using the latest Intel chipset drivers???

[patrickadizzle]

Ok I'm back.


Just wondering what the name of the speed step thing is in the bios.

I have disabled everything that sounds like it and yet it still clocks it self down. (cpu)
