Abit IP-35-E

[kai_]

i wonder what temps would be if you did the bolt mod like on the Pro on just the PWN heatsink.

i'm going to be in the same boat as you kai. i plan on watercooling my cpu and eventually getting a 45nm quad. as much as i love this board, issues with high PWN temps when paired with a quad is the only thing i'm worried about and i also don't want to add another fan to my case just to cool it.

would using copper ramsinks replacing the PWN heatsink help in temps?

After much messing about (I really need to get a bigger case!), I just got the whole motherboard out and took off the PWM heatsink and also the northbridge heatsink.

On inspection, the PWM heatsink is actually very concave(!), measured with a straight ruler, there is an alarming gap in the middle. This also resulted in less than favourable contact on the middle sets of chips the heatsink is supposed to cool. Unfortunately, I don't have any sandpaper right now to lap (and nor do I really want to) and so a new layer of Arctic Ceramique was applied, with a thicker bit for the middle so that more contact could be made.

At the same time, the northbridge heatsink was reseated as was the cpu waterblock.

Everything was put back into place and with great expectations, I fired it up and started priming away.

The short of it all is that the PWM temp is now 113C (!), which is still very high, but better than 124C, a drop of 10C. As for the CPU, it now reads: 54/50/55/55C across all four cores. (I don't know why core 1 is so low, it was like that before too) This is after Priming small FFT (max CPU) for about an hour (still going), again at 378 x 9 = 3402MHz, CPU-Z reading of 1.320v (1.415v in BIOS).

To be honest, I'm not really sure what to do next.

There is little benefit with the bolt-mod if the PWM heatsink is flat. Unlike the IP35 Pro, the PWM heat sink on this board should provide good contact with only two pins and no heat pipe.

How do you expect to evacuate heat from the heat sink without air flow? This is heat transfer 101!

In my first post, I aimed a 12cm fan (running at 7v) at the PWM heatsink, which reduced the temperature at load to 85C.

There is also an exhaust fan (12cm) directly above, as well as the PSU (again 12cm and exhaust). There are also a further two 12cm fans exhausting air near the front top of the case.

It seems that the PWM area just runs very hot on this board. I've read reports of people who manage temps of 65C on load (with this board), but I can't see how this figure can be achieved unless you point a delta at that area.

were they running a quad? 65c PWM temp sounds like a dualcore.

Supposedly. Take a look through the massive thread at http://forums.anandtech.com/messagev...&enterthread=y . SerpentRoyal insists that it's possible to run <70C at the PWM with a quad core.

Personally, I don't.

A 120mm @ 7V has very little air flow. Your problem is the concave PWM heat sink and lack of air flow. It's that simple. Heat transfer with paste is piss-poor. I'm seeing about 45C PWM nominal with a DC around 3.5GHz. Maximum in a hot room while priming is 53C.

The output devices on this board is IDENTICAL to those on the IP35 Pro. After putting a small fan on the Pro's PWM circuit, the temperature went down from 80s to 60s.

I think the heat transfer is actually very good - how else would you explain the heatsink to be burning hot to the touch? Heat transfer with paste is poor? How do you explain that one? It's got to be better than using the thick tim pad that was supplied, surely? I can't use Arctic Silver since the temperatures get too high and at high temps, Arctic Silver becomes conductive.

A 120mm fan at 7v provides more than enough airflow - especially when it's pointed right at it in an open case. (I'm still in the testing phase)

You are seeing 45C simply because you are running a dual core processor. I'm running a quad core. Although I can't prove that quad cores run the PWM temps higher (than dual cores), it is generally regarded as so.

[furballi]

If the heat sink is hot, then there is insufficient air flow to cool the heat sink. Others have seen sub 65C PWM with Q6600 @ 3.7GHz.

Go to the library and get a few books on heat transfer...conduction, convection, and radiation.

new beta 14 bios, this is 14-05 not the 14-04 which was posted before, just found this at the abit forums

Using GTLREF 67&#37; and bumping vcore to 1.43 v BIOS (1.38 actual) and MCH to 1.47 v I was able to get a Q6600 G0 to 3280 MHz and abit IP35-E to 410 fsb. Ok running f@h SMP 24/7. Air cooled with Scythe Mine B. I was wrong about the NB, it's actually cooler than the gigabyte P965-DS3. Board runs fine at 410 fsb but will not post at 450, and I permanently killed the onboard NIC trying to post at 450 fsb.

[ziddey]

how'd the nic die? did you juice vsb (vpcie) too much?

with a better heatsink, you might be able to just do 9x400=3600

[JVguest]

I haven't juiced PCIE at all. I assume the board has a PCIE lock, so why would it need juice? I'm not even running a PCIE card, just an old 2 MB ATI PCI card.. It's a known problem for onboard NIC to go when running fsb way out of spec.. my P965-DS3 NIC also conks out when the mobo is above 480 fsb, but it came back at a lower fsb. I had to clear CMOS by popping the battery and removing the ATX power cables and shorting the CMOS jumper for a good 30 sec before my abit IP35-E board would POST after a failed attempted overclock to 450 fsb at only 63% GTLREF. 67% is a MUST on this board for high fsb quad core overclocking. Increasing MCH stabilized booting into Windows.

I find it unlikely that f@h would be stable at 3.68 GHz (next multiplier up) and along with increasing vcore requirements, makes me not interested at all in running it faster than it is now.

I just replaced my P965 DFi with this board.
Specs : Q6600, 2GB Crucial D9gmh, 8800GT.

How do I go about flashing the bios? will I see improvements over the stock bios I have? IS there any bios CD's that people have made much like the Tmod's DFI bios/utilites disk?

[ziddey]

I also made the switch from dfi, but my ip35e is dead at the moment. You can flash from floppy, from windows, etc, similarly to dfi.

[aiya]

most recommend flashing with a floppy/flash drive method. if your like me and lazy to break out the floppy drive, you can do it in windows with FlashMenu thats on the cd. just make sure your running your system at stock clocks so you don't get a halfass flash and screw up your board.

[lolhalol]

yeah same here.. im too lazy to break out the floppy to. i use the flash menu since the first bios release came out.. flashed every bios since.. so far no problems.. just make sure u clear cmos before flash ( to make sure ur system is running at stock , so no unexpected crashes ) and after as well ( common sense) ..

[balewolf]

Im running my e6600@3.6ghz 1.435 vcore droop makes it around 1.38 my pwm under folding never tops 60c usualy never even hits 55c. I got a small chipset fan mounted on top of it. On the nic issue i had my board up to 480fsb and never lost nic and i ran it at 450x8 for like 3 months no problems. Had to drop it to 400x9 when i got some free ram and wanted to give my pc 4gigs and run vista 64bit.

[balewolf]

nice dan those 21xx chips are great overclockers but i love my e6600.

[danmoody]

thanks whats the max voltage you think i could push with air?

[nzbleach]

1.5 with that cooler. 1.6 if temps permit and if your crazy. this is XS afterall.

[GripS]

This board is badass for the money. I just used it for my friends build. The double post is slightly annoying but it overclocked very easy. The same chip that needed 1.42v to run 3.2ghz on my DFI P965-S only needed 1.35v on my buddy's build with this board. I almost wanted to swap it out for my DFI. I'm too damned honest though.

[balewolf]

grips instal bios 14 it nearly wipes out the double boot. Iv even had my pc taken apart and when i pluged it back in no double boot.

[The[R]eaper]

thinking about getting this board, but the egg seems to not carry it anymore. anyone know where to get it for the price the egg had? i think it was around $87.

thx

whoops.. nvm found it.

[danmoody]

ill go with 1.55 maybe 1.6 i have an l2 chip it feels like it has a fsb wall of 356. but i also havent pused more than 1.4 thru it ill give it a try my goal is 400fsb

[danmoody]

thats how i cooled it before the ac freezer7pro
