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

[C-N]

sorry...i wasn't criticizing you...i was trying to express that i think to many people put to much emphasis on orthos or prime 95 for 8, 10 or 12 hours when in reality 99.9% of us will never run a program that will consume 100% cpu usage on all four cores.

one guy made a good point about doing orthos or prime 95 for "12" hours...he thought he was stable but his game would kick back to the desktop after a short period of time running it...so...there are no guarantees with orthos or prime 95 if you can do that for many hours...his fix for the game dropping back to the desktop was to increase the vcore.

that is why i am not so fixed on doing it for many hours...if i get 30 minutes that is good enough for me.

No worries & I totally get what you are saying as I have had many rigs that run Prime/Orthos then fall over in games or corrupt windows days later but for me personally I run my rig hard 24/7 for pleasure/gaming & I run a small business from home on it so I run every test there is before calling my rig stable.

Anyway forget stability for now what I was getting at earlier was I too can bench DDR1200 just like viper with this board @ 400 x 9 but my point is its slower in PI, Sandra, Everest etc etc than DDR1080 450 x 8 so as good as DDR1200 sounds its a no brainer for me.

I am all up for finding more power/speed from this board just the same as everyone else here but when I see other users struggling to match what they saw here at xtreme & failing blaming there hardware trying to get there rig stable enough to open notepad when the original posters rig was only 14seconds/PI 1M stable in the first place I feel obliged to comment particularly when there is no useable benefit as well.

=====

My basic point from 4-5 pages ago still stand BIOS 12_b02 is not as stable & doesn't offer any performance gain over official 11 & I ask anyone to chip in with there comments after all thats the whole point of a BETA BIOS (work out issues before release)

i set mine to around above 700 and then turned it down slowly.

i watched voltage in bios and watched it go up as i started reaching the 680 range...

you can set it to 635ish and then just tweak it from there. but the range is right.

I need to know if you set the variable resister to 700 BEFORE the two wires are soldered to the board or did you set the resister to 700 AFTER the two wires are soldered to the board

Thanks........

it doesn't matter.

if you have a 1K VR then set it to 1K and then tweak it down... you won't know what resistance your set to but you will see your voltage go up in the bios.

i set to around 700 before i soldered it on so that I'd know that i didn't have to turn it too much before I was in the range I needed.

What made my mod a little more difficult was that i was using a 10K VR since I didn't have a 1K VR. Else I would have set it to 1K and just tweaked it down.

If you have droop at idle, you will notice your voltage go up as you push the resistance down.

Pictures of vdrop mod anybody?

Always do it before. For my mod I ended up having to lower my resistance a boatload before my voltage went were I wanted it. I'll post pictures of my mods later

Observation...

It works fine, OC is the same as previous version but "Wacks Temps"... Makes you feel like you have some kind of "Super Cooling".

Regards-

are you referring to the latest beta bios...if so, try the official 11 bios (2nd release)...it will give you more accurate temp reading...i bounce my temps off from coretemp 095...in idle conditions, coretemp should be about 10-11C higher than the reading from Uguru...i think the beta was making it at about 14-15C higher.

you can do it either way....but if you have a 10K variable resistor then it behooves to preset to around 700 ohms before doing the soldering.

Ok just a quick update, I have managed to get my L724A760 GO Quad 6600 stable at 3.6Ghz, ran Prime 95 for 10 hours and Orothos for an hour just to see if it would run.


I found that my problem was in fact vdroop, I am at 1.5v bios, 1.45 idle and 1.41 load, a .09 vdroop under load geesh lol.


I wouldnt think 1.45v at idle would "hurt" the cpu for 24/7 use but as it has been said before no one really knows, I am running on water but its an Exos2 so its not all that great, my cores were hitting a high of 67c at load and I am at 39, 34,34,39 at idle so I think I should be ok.


I have a feeling that if I can get the vdroop fixed and get better cooling this chip could do 3.8Ghz easy enough, but I dont have the guts to solder on this motherboard, I can solder wires well enough but after an hour of so of soldering on an old slot A to 370 slocket I have come to understand that I SUCK at soldering anything but wires.

[Ace-a-Rue]

0.13V from indicated BIOS value to uGuru sensor whilst under load.


Yeah I thought the same thing about the +12V rail. Tried on three PSU's:
1> Silverstone ST85F (70A +12V)
2> Hiper Type-M 720W (brand new; 56A)
3> Corsair 620W (also brand new; 50A)

All give identical results.

you need to read your vcore right off from the board...i know the drop is not that bad...uguru does fluctuate downward below the actual voltage...whatever vcore uguru peaks (tops off) to in idle conditions that is the actual vcore going to your processor...there is a picture in this thread that show's where to read the vcore...its basicaly right next to the PWM heatsink, in towards the cpu socket...if you were standing over the board (facing to the backside or port side of it), you would see a couple of tiny resistors to the right of the PWM and going towards the cpu socket...one of those is where you would read your vcore.

My system goes from completely stable @ 1100 4-4-4 2.2V (4xMemTest in windows, MemTest86+ in "dos" etc) to unstable @ 533 5-5-5 2.2V or anything in-between and then back again to stable again for no particular reason.

Currently running 24/7 @ 1028 4-4-4-9 2.25V. Well trying to run 24/7, it BSOD's every now and then for fun

i bet you are switching FSB to memory ratios...right?...that is why one frequency is stable and the other is not...i cannot get my 1066 strap to be stable unless i back down the FSB about 20 Mhz from what i work it at using the 1333 Mhz strap....now...a few are doing very well at the 1066 strap since they have the right memory for the board...i believe crucial ballistic PC8500 stuff works superbly on this board with the 1066 strap.

[Dredd]

it means that you have to tweak every area until you find the sweet spot

Well, like I said everything inside windows worked. Memtest stressing memory directly showed some errors. I've tried everything and I suppose all I can do is leave it where it's at because I am using all 4 slots and it's not really slow by any means.

I can't seem to install Vista. It says upon install that Windows could not find what it was looking for. I have the hard drives set to IDE at the moment. Do I need to install any drivers before the Vista install?

Zero format the HDD, then install Vista. Note that Vista will not work with FAT32 partition.

[Ace-a-Rue]

No I am not fearful of Overclocking actually I am quite good at it! I just have not owned a Abit Board before and some settings are not familliar to me on the IP35 Intel Bios because I have only used two Intel board since C2D D.F.I Infinity (POS) and the EVGA 680I another POS!

tell me the bios settings that have you unsettled...i will and others can address those.

Actually the TEC cooler aint too bad @3.2ghz Q6600 I peak around 64-66c Full swing 8hrs on Prime which I would say is pretty good for my Wimpy TEC

that's it...the TEC can not handle a higher overclock with a quad especially a B3...i tried one already....my Ultra X beat it out...who would of thunk it!

I plan on getting a really good water system from Newls1 when I have the money..cough ...cough...that is unless you wish to further the cause

sorry buddy, no donations at this time.

You could solder the "legs" of a small 0.4" x 0.4" 25-turn VR directly to the board. Fry's has this item ($3 for a pack of two).

.Off to try it.

[tomati]

Ok here I go,

personal mosfet heatsink , will test it tomorrow to a friend as I don't have my cpu yet.

[The Viper]

heh guys, i was under the impression that keeping with a 9x multi is quicker then using a 8x or 7x?

NOW...that is XTREME!

[Ace-a-Rue]

it appears that this board scales on performance as you escalate the FSB upwards using the 1333 memory strap...now...if you stay at 9x, you need to try the "1066" strap to maximize your performance...i can't really get there myself.

[emoners]

whoa tomati, is that a Thermalright HR05?

do you know at what FSB the board switches to 1333 strap with a 9x multi?
Ill have to give 8x a try if its offereing quicker performance in benchmarking

it is based on FSB to memory ratios..this will help:

Did you braze the base on there or how did you attach the copper base to the noctua
