**Official ABIT IP-35 Pro Review/Overclock/Guide Thread**

[strange|ife]

ya make sure C1e eist are off on intial testing, you can possbily enable them later once u are comfortable with your overclock. I got my system stable finally, and sitting at 3.6ghz. 1:1 with EIST&c1E enabled to compensate for the 1.52 vcore i need to set. i would prefer it to idle with lower voltage.

to above poster ur board should have no problem doing 400fsb with no more than 1.33mch 360fsb u could prolly leave the voltages stock, maybe a lil VTT.

I just finished testing my Patriot memory and ended up with 1032mhz @ 5-5-4-13 1T. I'm only testing out one 2x1gb kit currently but I'm quite satisfied with it. I set mch to 1.33 and so far I'm at 485FSB and going. Can you please explain the CPU VTT, etc. I'm not too familiar with these, including ichio and all that stuff Thanks.

I've got a strange problem. My motherboard's great and completely stable in everything I throw at it - except when I try to put it in S3 standby.

At stock speeds, it'll come out and have the IDE controller detected as a removable device, with my old HD showing up on there.

If I overclock it much (I think at all), the computer simply refuses to come out of standby. I have to hard reboot it.

I've tried searching around, and don't see any mention of other people having the same issue. I suppose I don't really care much because I don't have to use standby, but it was a nice convenience to have my computer shut itself off if I leave it idle for an hour or so, since it's a tiny space heater as it is.

Here's my vmod, nothing special, I was in a rush and didn't have any hot glue

I noticed the 1 kohm resistors come in multiple flavors based on power rating: some are 25W, some 50W, 100W, etc ... what's the difference between the power ratings and which one is needed for this mod?

Thanks

I'm doing the vdroop mod posted above right now. But I'm using a glue gun which I find difficult to the 'Xtreme'. How can I verify the mod worked? I mean should there be absolutely no vdroop at idle and then burn? How many turns am I supposed to move that resistor?

Don't perform the mod withouth a DMM! BTW, it's not how many turns, it's the resistance that you want in ohms. So measure the the resistor with a DMM. Should be 620-650ohms. You can verify if the mod worked by stressing the cpu and checking the vcore with a DMM. There shouldn't be a huge droop anymore. JB said you should leave a very little droop just incase.

I'll be doing the vdroop mod later on, but I just spent hours trying to run my 4 sticks in 1t while keeping tight timings. I finally got them at 800mhz 5-4-4-12-1T @ 1.9v. Now I can OC I love this board. It's just easy once you get the hang of it. uGuru is better than what I thought it would be.

[Masami]

A very stupid question... but the pci bus is locked at 33 mhz by default or not?

[Hazzan]

so far so good with my mod Vdroop...

Is there a software option to control fan speeds? I was planning to do volt mods, but I just wanted to check other options.

Wow I kept forgetting to press apply for the fan settings.

But for some reason the settings will not work for my CPU fan. It works for all my other fans but that one. It is also the same fan model and make as my others.

Thank you.

you need to clear cmos to get the cpu fan to work again...i found out that the controller resets to full speed if you change any bios setting after setting that particular fan controller up....and...the only way to get it to function again is to clear cmos...i am working with the 12.B01 bios...i emailed Abit through their black box about this problem.

my cure was to put both of my cpu fans on aux 1 & 2 fan controller heads and those two work with no problem at all when you change the settings....just put another fan sensor on the cpu controller head to keep the board from shutting down.

Thank you. Can I just disable the shut-down and beep for the CPU fan if I put it on a different header?

[Ace-a-Rue]

try it to see.

Has anyone here had problems with the combination of a Corsair 520W and the IP35?

I get a high frequency noise coming from the motherboard, when I use my Corsair. It gets louder and more obtrusive under load. It is quite loud and I can clearly hear it even with the cabinet closed (P182)

When I switch to my Seasonic S12-430, the noise almost disappears.

Are you sure it isn't coming from the power supply itself?

It would make more sense if it did, but it sounds like its coming from the upper part of the motherboard. If I hold my ear right next to the PSU, there is no noise except for a little fan noise.

[Alik4041]

Anyone having problems with coretemp? It causes and automatic reboot for me when I attempt to run it. Using version .95. I'll try.95.4 beta

I get it too but only under heavy load at high clocks 3.6+

I have a 500w antec neo HE. Its weird, it does sound like the mb but its not a big deal bc I dont keep my clocks up that high.

there are 4 coils embedded in individual cases with silicone around the coils...if there is not enough silicone, it will make harmonic sounds..these coils are just next to the PWM heatsink....higher load affect these coils by making them work harder, i presume, at dampening the pulses in current....you can always add more silcone.

Hmmm been hearing the same thing and I have been trying to locate that high pitched frequency noise for a couple of weeks now. It sounds like a very faint dog whistle sound and I just replaced my PC-PC Silencer 750w for this OP1000 a couple of days ago and I have even put my brand new G-Skill HZ RAM in hear to see if it was the Crucial making the noise and its not that either and the friggin noise is driving me nuts and my hearing sucks to begin with so its kinda pissin me off!

I get the noise too with a S12 500w and ballistix PC8500 ( not often) but I swapped to corsair value ram and get much more noise, waiting my ballistix back from sav .

yes.
the CPUFan header on the Pro will only control a 4-pin PWM fan - if you have a 3-pin & want to control it move it to another header.

I use OCCT to load my PC. So I run it and around 10min into testing my PC freezes. The mouse and keyboard(G15) do not respond. The only thing that works is the timer for OCCT.

Is this normal? I am usually able to work even with OCCT running 100%.

This also happens with .exe Memtest.

I reset the clocks to all default and gave the vDimm a little more. (@ 2.0v) Still the same problem. What might be causing this?

That was my initial thought too, that it was the coils.

Now I just don't know anymore, since the noise is practically gone with my Seasonic S12 PSU. If the noise is coming from the motherboard, it must be something with the combination of mobo and PSU.

Thing is I would really like to use my Corsair PSU because of its modular cable system.

It is a power realated issue though for sure. I run a Q6600 @ 3.6 and if I go back to stock clock the problem pretty much disappears.
