agree, the pwms on my board is also limiting my OC... Can go to 3.6 on my q6600 easy and prime a bit until the pwm overheats... haven't really had the time to do the screw/bolts mod yet but ill post some results after i get a chance to do them.

Aslo, it seems like everytime i take my computer apart and reassemble it, i have booting problems and have to reset my cmos. Like last time i took my comp apart to remount the mobo heatsink with ceramique. After putting everything back together, my comp would just fail to boot. It would power up for one second then turn itself off and repeat... had to reset the cmos jumper on the board to solve the problem =/

IIRC he was able to fix it by changing the Uguru default skin and/or transparancy.

Thank you:clap: .I'll give it a try.

Edit:It works now with a lower transparancy.Also thanks to Turbodream.

So you can't run your ram at a slower speed then the FSB? The lowest divider is 1:1?

Am I correct?

I mean, my chip has more to give then my ram does, how can I run the FSB up and max out my CPU while allowing my memory a more relaxed time of it?

---

every intel chipset based board is this way. Regardless if you spend $250 for the Asus P5KC Deluxe or $79 for the Abit IP35-E

I just bought a IP35 PRO to replace this POS EVGA / FOXCON hows this thing overclocking Q6600 GO?

Any advice about 2 2x1gb kits that works without problems in this board?

That bolt mod is fantastic. :clap: Dropped my pwm temps 20C! I also stuck a 60mm fan bw my tunic tower and the board, it fit perfectly, the tunics fins hold it down and it blows air right over the pwm. I also loosened up my tuniq tower a bit, bc I noticed that my board was warping around it and it lowered temps considerably. Now I am not breaking 60C when priming, with like 26C ambient @ 3.5 ghz and 1.38v!!! :) :)

is that really an actual 0.13V droop from idle to load or a combination of the initial value not being what is set in the BIOS plus a droop for idle to load?

4> PCI based Gigabit Ethernet. .... que cosa?

this appears to be a design decision to allow the continued use of the other PCI-E even when the x4 is in use - on mobos like the Gigabytes using the x16 + x4 disables the other PCI-E slots.

---

droop is normal for all boards...that is by intel design...they allow for droop...my droop under load is around 0.08 to 0.09v...you might have a 12v rail problem.

2> Random system instability (RAM gets errors whilst @ stock, then works perfectly for several hours even @ like 1100 4-4-4 2.2V; seems to cycle between the two). Restarting, and powering off and on don't seem to effect.

---

i tell you right now..you are running to tight of memory settings for DDR-1100...you might think of boosting your Vdimm to 2.4v to see if that helps...OR...raise your timing to 5-5-5 with 2.2v...performance is barely going to change by jumping to 5-5-5.

you need to do my heatpipe mod to help with the PWM temp and NB temp...top of the page

---

nothing wrong with my connection...i haven't seen any difference between PCIe and PCI based network chipset....now, if you are loading the PCI bus down with other hardware, that might affect overall network performance.

5> Randomly not booting after resetting BIOS (even taking out battery / power cycling / etc). I've had errors ranging from 7B to C1 to 0D - 0D isn't even mentioned in the book.

---

C1 is a problem reading the memory..could be your main problem overall...might try some other sticks or just take it down to one stick...switch out the stick to try the other....try the other slots to see if one slot is better than the other.

which mod did you use?

@Ace-a-Rue out of curiousity did you hook up the additional 4 pin molex lead to the board and is it even needed without a second GFX Card?

i tried it with and without...i noticed no difference but my setup is only using the 4x and 16x slot...if i was using the 1x slot, it might make a difference...the 4 pin plug is meant to be used as an auxillary or supplemental power...probably if the board traces had higher resistance and therefore dropped the voltage, i would think the additional or supplemental power source would overcome that.

The same one you did except with 3/4 inch bolts. I used as ceramique all over the pwm, nb and sb. It helped everything a ton.

Cool!:up: ...glad you had good success with my mod...really not totally my idea...someone else had mentioned about removing the heatpipe and adding either AS5 or ceramique but not any bolts and nuts...so...i just took it to the next level...i wanted to save the heatpipe system and not bastardize it like i did to my QuadGT board...i hate adding more money just to beef up the cooling system...it looked like the heatpipe system should perform nicely...once i removed it to do the mod, i understood why the temps were high with it in the original configuration!

Ace, I did your blot mod and am I ever glad I did. An this is without ever even running the board at all. I think I found why some people may be having such bad PMW temp problems. I think you will see what I mean in the picture. And also, 1/2" bolts worked just fine for me ;).

Pntgrd, and bfox2,
what is your current pwm temp right now? and how much different temp before the mod?

YES!..it is what i had but mine was a little worse...i hardly had any indentations and the TIM just peeled off like olive oil was coating the bottom of the TIM!:D

anyway...i updated my post with using 3/4" bolt length to make it just a little easier for everyone...you must be like me;) ...one who likes to work in cramp spaces, under the most extreme conditions and upon success, walk away with a great sense of satisfaction!:up:

Sorry Goone, no pre temps. I haven't even installed the thing yet. Got my Stacker for it all today. Did this first and now I am in the process of lapping an Ultra 120 Extreme. I should have had this done already as I have had it for a week.

Of 3 mb's in the last year: Epox 9npa, DFI NF4, and this, all have had high PWM temps when doing dual burns. It ranged from 80c to 105c, 80c being on a cool day. Ambients were about 28c. I don't see what the big deal is about this, does it lower your overclock? I thought these mosfets are rated to handle 135C+.

i think most relate lower temps to a higher success with overclock...i believe that is where it comes from.

Right now my pwm temp is 45c, idling at 3.5ghz. Loaded it gets up to mabye 65-70C ish depending on ambient. ambient being anywhere from 80-95F(i live in arizona, its 115F outside). Before i was hitting 65C idle and 85C priming.

Its definetly worth it, even if you have to take your machine apart:up:

Well, my lowest pwm is 77c with a fan over the pwm hs. That's the lowest I've ever gotten mine to. I get 50 to 60c just at idle just 10 min after a cold boot. Depends on the vcore too I guess. I mean, how important can this be? Is there a voltage ripple if these get too high?

Thanks guys for the replies, right now idle at 49 load could get up to 80-85 with a fan over it, this is running with quad right after upgrade from 6600. Too much hassle to take this thing apart.

C'mon man DO IT!! you know you want to:D

Got to be honest, after bolting mine down and using mx-1, I didn't really notice much of a difference. I did take care to make sure that the heatsinks were bolted down flat and securely.

Maybe mx-1 wasn't the best choice in this instance, don't know.:confused:

As I said previously, on my setup the greatest impact has come from replacing the 40mm fan with an 80mm fan over the PWM area and it's surroundings. Temps have dropped by 10-20c.

On previous small Ftt runs, my PWMs were hitting 83c. With this fan, and even higher voltages, I'm hitting 63c.
