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

[Ace-a-Rue]

lol clearly you were never a fan of DFI then

NOPE!

[Ace-a-Rue]

But what do you mean, skipping say the IP45 or 48 gen would put off a lot of sales? Why wouldn't they sell as many or more of a supposedly faster chipset like the X58?

abit is taking a chance of turning off some of their customers if they bypass certain chipsets, which support 775 pin cpu's, to jump into a totally new chipset that requires customers to purchase a new processor...buyers will upgrade boards with the same cpu..but..upgrading board and cpu can be risky especially since the economy, at least in the USA, is struggling.

i think abit is suffering financially so they are forced into cutbacks...i heard that abit went from 4 working bios engineers down to 2...could be sign of the times of a world economic slow down especially with the price of a barrel of oil just about affects every product we buy...people don't realize how much oil is part of the world economy, not just for gasoline, petrol or whatever name you use...you are talking about plastics, stryofoam, chemicals, cosmetics, asphalt products, polyurethane foam found in furniture and beds and plywood adhesive...there are more!

Well since Abit is slow about the P45 board, I decided to pass the time by doing a little cooling update to my IP35-Pro. Don't know if it will be any better on the NB and SB but I have always had problems in the PMW area. And I know my new 4870 is going to like it's new friend.

[loonym]

Great stuff Pntgrd I was also thinking the same now that dog days are here. Next time I crack the case where the ip35 stays I'm changing sinks and going with copper on the mosfets.

Accelero S1 can't cope with HD 4870

Goes over 100°C

According to a post over at forumdeluxx.de, Arctic Cooling's Accelero S1 rev.2 paired up with the Turbo Module fans can't cope with the heat produced by the HD 4870. According to the product page on the Arctic Cooling's web site this one supports ATI's Radeon HD 4850/4870 cards.

The problem however isn't with the card's GPU but rather with the VRM part of the card, which gets quite hot when cooled by the Accelero S1. It just seems the VRM part gets too hot without a heatsink and that's it. The situation got a bit better when the Turbo Module fans were replaced by a 120mm fan, but 98.4°C on the cards backside is still a lot. The product page on the Arctic Cooling site also shows that Accelero S1 comes with a special heatsink for the VRM but it is unclear from the pictures if this user has used it or not.

Of course, Arctic Cooling has released a new Accelero Twin Turbo cooler that comes bundled with memory and voltage regulator heatsink and it packs much more cooling power with dual 80mm fans. Still, it's nice to know that you shouldn't try the Accelero S1 without making sure that you placed a heatsink on the VRM part.

I hear ya on the crappy economy, and I think there's worse yet to come. Hopefully abit can get things done with less resources, but it'll probably be a tough go.

[Ace-a-Rue]

it is funny how this economy thing swings and it always happens at the end of a two term president...same thing happened to bill clinton...the economy was smoking up to his last year in office and bam, as he left office the economy tanked; additionally hurt by the 9/11 attack...so, we will be in for a rough ride for the next year or so...what has me worried is all this banking problems...the INDY-MAC bank failure has to be alarming to anyone even though FDIC has stepped in....now you have Freddie and Fannie (mortgage brokers) in financial trouble...the whole freaking congress and president have been asleep at the switch (except for ron paul)...we will regret the day when we went off the gold standard...we print money like it has no end in sight!...we need to reduce our foreign oil imports...lets freaking drill, drill, drill while we work on alternative energy sources...we have to start some where.

i diverse...finished.

Aztec, I wish I had taken a pic of what I did. The S1 comes with a sink for the VRM area> The S1 comes with a sink for that area on an X1950. Only problem is the bolt holes do not line up. But with the help of my trusty old Dewalt, a new hole did appear and there is now a sink on the five chips in question. I ran ATItool 3d app for over five minutes and the temps rose to 63c, which is a far cry from the low 80's with the stock cooler.

[18 is # 1]

once you go to 4 gigs, you will be lucky to even do PL=6...4 sticks will be the harshest scenario; next comes 2 x 2gb memory scenario...your easiest overclocking memory scenario is 2 x 1gb single sided sticks.

Well just ordered 2 more from Tankguys...we'll see what the Pro will do with it. I just couldn't find any 2x2 kits that I was enthused about.

When using 4x1 GB sticks, which bios settings (voltages) will change vs. my current 2x1?

Sounds good. Did you up the fan speeds?

Man this thread is amazing, 271 pages and still going. I just received a Q9550 yesterday and have it fired up in my IP35 Pro. I am going slow on this as it is my first 45nm chip and don't want to cook it.

The fans won't plug into the 4870 so you can't control them that way, but I have an idea that should be more than adequate. I have 2 Artic Cooling AF 12025 PWM fans I tried in push/pull in my TRUE. Even at high speed they are pretty quiet. I would guess they should handle the job quite well. I am going to have to change the fans in the side of my Stacker. I now have some orange bladed YL's and I need some more airflow onto the IP35-Pro. Even with the change in the coolingon the PMW area, and with a 40mm fan on it, it is still too hot for any summer o/c past 3600. It is a hard area to get any flow across as it sits right in the path of the TRUE exit and a 120mm exhaust fan, but below the airflow. I have some 3-speed Antec's I may experiment with so see if increasing the side intakes will help.

[leoncc]

anyone know why i only have sound coming out my left speaker?

i have the 2 jumpers set on pins 5-6 and 9-10 is this right for using HD Audio from the back panel? according to the manual putting jumpers on them pins disables the f/l audio panel right?

thanks, really annoying was fine when i was using the front panel.

[ecidious]

can I trust the uguru software's measurement on vcore? BIOS is ~0.09V higher than uguru, so I'd like to just bump the BIOS up a little higher and go for 3.6 GHz on my G0 Q6600 L745A793, VID 1.2250 system in sig

is it worth updating from bios 14?
also, any suggestions for PWM cooling with a TRUE in the way and a stacker case? (besides a box fan )

[loonym]

Where did you get that 9550 sig? The last 3 I've got were all rev C1 so I'm somewhat surprised to see a new C0. Do you have the batch #? Have you tried pushing it any more?

Still letting it set in while I play with the other rigs. It is ridding @3.5 for the moment. I plan on taking it up some more this weekend time permitting. But this is a Kruncher so I hate to have it down for long while I play.

[Ace-a-Rue]

any update on the IP45 or IX48

[kadozer]

need a new p45 board about to pull the trigger on an Asus Maximus II, but holding a bit longer to see the Abit p45 boards. Wish they would announce an expected date.

[Ace-a-Rue]

supposedly in the IP45 thread, it was said either the 1st or 2nd week of august.

[loonym]

Shouldn't review sites have samples by now if release is imminent? I think they would want to promote this as much as possible since they're already late to the party.

[Ace-a-Rue]

the AMI bios outside consultant might be still busy at work correcting the problems...they switched over to AMI from Phoenix bios

[conzymaher]

Is it possible to use the lower PCI express slot when the top one isnt in use? I need an answer asap!

Building a small form factor machine and I dont think I will be able to use the upper slot

Thanks guys

absolutely!...the speed will only be 4X

[conzymaher]

noes!

Can it not give 16x to either slot?

P.s I think I can make it fit in the upper slot now but would be nice to have the option of using the bottom

primary slot was set to 16x and secondary slot was meant for 4x...but...your performance will probably be only 10% less at 4x versus 16x.
