It is a simple follow up to B11.09, fine tuning memory latencies, getting temp readings correct, and further improving Quad Core compatibility.

Question for the users of this board -
Has anyone been able to go higher than DDR2-1100 with 4GB of RAM? I am on my second board and anything over DDR2-1000 with 4GB of RAM under Vista64 is extremely unstable. I replicated this problem with five different memory vendors and have more RAM arriving tomorrow, of course, abit has no issues in their labs.

I've booted to windows and ran some quick tests at just over DDR2-1100 but needed 5-5-5-18 2T and over 2.3v. After about 5 min I went back down.
You're right though. I booted at DDR2-1066 5-4-4-15 2T 2.25v and it memtested stable. Windows froze up or BSOD after a time.
I also doubt that Abit or any motherboard manufacturer tests extreme overclocking with 4GB in their labs. It would be hard to pinpoint the cause. It could be the memory type, IC, voltage, BIOS problem, NB voltage, strap.
BTW: 1:1 and 1:1.2 memory ratios are 1333 strap, 1:1.25 and 1:1.50 are 1066 strap, 1:1.66 and 1:2.0 are 800 strap

This is the first upper end P35 board to have these issues. I am also Memtest stable up to 1100 or so and then PC WorldBench 6.0, BF2, Prey, Nero, QuickTime, you name it will lock immediately during testing. CAS 3 is a not stable at 800 currently while the other boards are happy at 3-4-3-9 at 2.25V, takes 2.35V on this board to even get it posted, much less enjoying the BSOD show when Vista loads.
Will run some tests with IP35-E this weekend and repost. Board is Orthos stable with 512MB x 2 DDR2 800 Kingston ValueRAM (strange logo on chip) up to 602MHz. Also okay with 1GB x 2 DDR2 800 Kingston ValueRAM @ 580MHz. All tests performed at 5-5-5-18-2T with 2.1Vdimm.
Don't have 4GB of high performance RAM but I could combine these four sticks for a total of 3GB and retest north of 550MHz under WXP Pro. These are ValueRAMs so they may not be able to play nice together at such a high frequency. Have you tested 4GB/DDR2 1120 with the IP35-E? The E's BIOS appears to be more stable than the top-of-the-line IP35 Pro, at least with my current configuration.

From what I'm hearing, they (meaning Abit) screwed with the NB latency in their BIOS. So high speed memory configs are not stable since the NB is running tighter latency. I guess if they had left it alone the end user could adjust memory timings and speeds more freely.
However, over at XS there are people running DDR2-1111+ on this board and it's solid. What did they do? I wish I knew...likely they have some high voltage on their memory and NB.
Anyway I'm not sure how much difference there is between memory bandwidth and latency on this board vs others. That's what we're waiting for you on
edit: have you tried the older official release BIOS 11? If not, maybe give that a shot just to see if the B12 was tweaked too much.

GRINS yeah
Loweringthe multiplier to x6 or x7 isnt really pushing the board is it?
However stable at 4981.fsb X8 (like i did) on a quadcore , is the best your goingto get im afriad. So in essence 468FSB , I will once again say that your 48fsb is very very good
Ido not even know what coolnig system he has. I mean at my 4981.FSB IM even PUSHING A D-TEK fusion block and thermocill PA120.3 rad, alphacool ddc ultra pump!
Be happy with what you have mate its a decent score.

The B12 that we worked with abit engineering on was suppose to cure the 4GB ills of B11.
I can run up to DDR2-1333 on this board with 2GB, the problem is 4x1GB or 2x2GB kits, they are just not stable under Vista 64 at various straps and timings. Anything over DDR2-1000 is a crap shoot at this point. I finally got DDR2-1063 dialed in (425FSB) but have to run 2.4V on the memory, anything less will lock the board under 3D06/Q4 as an example, same settings on the other boards results in 24/7 stable condition at 2.2V. I have spoken with several hardcore abit users, they are all experiencing the same issue. I had a few of the latest DDR2 modules show up yesterday and everyone of them had a problem.

I can run DDR2-1020 5-4-4-12 1T at 2.25v with this board and 4GB (4x1GB) GSkill HZ DDR2-800 (D9GMH) stable under windows and memtest. Like I said, 1066 was no good.
Interesting. No wonder I had a hard time running 8 x 525 1:1 with 4x1GB...
wonder if it'd be stable if i tried 2x1GB...
upping the mult up to 9x and dropping fsb to 470 1:1 seems to have solved my stability problem.
good find.

Hey guys, I just put together my system with the IP35 Pro motherboard, and everything seems to be running; however, my system is only reading 1 GB of RAM when I have 2X1GB sticks installed. I know it's not the RAM since I plugged the second stick in by itself in slot#1 and the system booted up fine reading 1 GB of RAM. I have also tried putting the 2 sticks of RAM in both DIMM1+DIMM3 and DIMM2+DIMM4 combos. Any ideas what I might be doing wrong, or could I just have a bad motherboard (everything else seems to be running fine).
Here are my computer specs if they would be helpful:
Intel Core 2 Duo E6850
2X1GB Crucial BL2KIT12864AA804 DDR2-800 4-4-4-12 RAM
Abit IP35 Pro
EVGA 640MB Geforce 8800GTS
OCZ GameXStream 700W PSU
Also, if you can figure out my RAM capacity problem, how do you set the RAM to DDR2-800? I know how to set the timings in the bios to 4-4-4-12, but afterwards CPU-Z still reads my RAM as DDR2 @ 400mhz.

I had the same issue when I installed my memory. Not sure what was wrong but BIOS and Vista would only see 3GB(3 sticks instead of 4). I pulled them all out wiped the connectors blew out the memory slot and reinstalled them and then the BIOs and Vista see the whole 4GB. Can't explain it but I thought I'd share.
Someone please post if they see the firewire problem get fixed. I really need a fully functional firewire port, and would love to buy this board. But if they don't fix that issue, I'm going to have to look for something else.
Bit-Tech had a comparison on P35 boards, and noticed this shortcoming.
http://www.bit-tech.net/hardwa.../07/12/abit_ip35_pro/7
As for my application, I'm looking at boxes like this:
http://www.m-audio.com/images/...s/big/profire_cout.jpg
http://www.m-audio.com/product...eLightbridge-main.html
1394a is supposedly 400Mbps, half-duplex. For this application, it looks like you need at least 32-channels input, 16-bit, 44.1KHz, = 22,579,200bps. I believe you can do this at 24-bit also. So that gets you input of at least: 33,868,800bps. Simiarly, if you wanted to do 16-channels of 24-bit, 96KHz, you would have input of: 36,864,000bps. Shouldn't be a problem, theoretically, but I have seen other bus cards fail below theoretical limits, so this issue doesn't make me feel too confident in using the builtin firewire on this motherboard for this application.
If we have 400Mbps to work with, and it is 80% efficient, that is 320Mbps data. It looks like Abit got 141Mbps in the bit-tech read test. So...
This has been reported to Abit, and as of yet, nobody has indicated that the issue has been addressed. If someone with the latest bios can do an HDTACH read test, that might provide some more light on this topic.
You can run as many test as you wish, but you'll come up with similar number...~approximately 15MB/s with 1394. USB 2.0 is fine at 30MB/s.
Ah misinterpreted. Not sure why you repeated your 15MB/s comment. It really just restates, yes, there is a problem. And yes, we don't have an answer yet.
so is there any way to shut off the bright red led by the main power connector on the ip35 pro? i havent finished the build yet (os install/etc), but that and the post reporter deal are pretty bright... maybe i'm just not used to having them.
