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

I don't understand why people keep recommending this board for oveclocking quads.

1. It has TERRIBLE Vdroop/drop or whatever it's called. I set a Vcore of 1.585 in the bios and under load it drops to 1.47!!

2. The PWM design/cooling is very poor. Any decent clocks and the PWM temps soar to the hight 80's. A fan over the PWM is a must for any decent overclocking.

I wish I had gotten the P5K premium or the DQ6 now tbh.
 
For number 2. I have 3.5Ghz, core temps: 58c average, PWM of 63c. No problem with that. Is the heatpipe/heatsink arrangement secure on your board? I have read about the odd case where there wasn't full contact being made. Very happy with mine.

because it does a decent job ;)

Vdroop is part of the Intel design spec.
On the IP35 you have 2 parts to the overall effect:
Vdrop where you are probably getting ~0.02V less actual to the CPU than set in the BIOS at idle - once realised easily compensated for.
Vdroop being obviously idle-load difference. You can increase Vcore to compensate & use C1E & EIST to lower it when not necessary.

Having said that you have probably the worst overall difference that I've seen reported as it's normally ~0.08V.
Obviously individual boards vary but so too does the PSU also have an effect & looking at your specs I wonder if you're pushing yours & it's showing signs of wilting.

What's your v.core? and is that with prime small ftt's. I've had a quick look online and quite a few others experience similar temps

I just sold my 2900XT (using a 6600GT now) so my psu is definitely not a factor. I know vdroop is part of the intel design spec but i'm sure even 0.08v is pushing it. Neither the Asus or the Gigabyte boards are this bad.

Good clocks there. Why don't you try for 3.6Ghz?

:D Would give me my 4000Mhz default on the ram. How accurate is the Cpu-z vcore? I take it that's the one to watch taking vdroop/vdrop into consideration. Both cpu-z and uGuru show the same vcore, it's only the bios that is out. I wouldn't want to kill my new baby lol :) What's considered safe vcore (as read by cpu-z if indeed that is the more accurate method?). I am sure for 3.6Ghz I would add 2/3c to my average temps. Not sure how much vcore I would need to add, I seem to be adding a lot more to gain stability for very little at this end of the o'clock.
 
Yeah thats how it is. Law of diminishing returns I guess. Problem with the pro though is the higher the higher the v.core, the higher the v.droop. So it's kinda difficult. Most high clocks either need great chips or volt mods.
 
Hi There

Im thinking of getting one after xmas just some questions though:

1. Will it support e6850 cpu straight out of the box without a bios update.

2. If i buy it after xmas will the bios be the very first revision or would it be an uptodate one.

3. Whats the problem with having 4gb ram, cause thats what ill be putting in it???

4. Will it fit in my akasa 62 eclipse case alright, should imagine so?
 
Hi
well i can help with 2 of ya questions . yes it will support e6850 cpu straight out of the box without a bios update. i have 4 GIGs of memory with no problems

Should be fine mate - the P35 chipset supports 1333 fsb chips and beyond :)

4. Will it fit in my akasa 62 eclipse case alright, should imagine so?

Again I would say it would be fine - my Lian Li has it mounted upside down and its fine space wise

Is it just me or is there not a bootmenu on this motherboard? - i dont mean within the BIOS its self, but saying pressing F8 just before OS load to be able to chose from say HD or DVD. seems abit backwards if it doesnt?
