you have the same difference that i have, about a 0.14v offset from bios setting versus actual vcore....i am using beta 16.b04.Quote:

you also have a low VID like myself, which is 0.9625...i can't overclock above 4.2ghz without overheating the cores and PWM temp...i use coretemp 096 to measure my temps...i get a 10 degree split between each pair of cores...weird, but i think that is intel's problem with putting in DTS sensors which are not reliable.
So Clear CMOS, and right away without any bootup take out the battery for 10 min?Quote:

Is there any way we could of killed two mem slots doing the heatpipe mod ?
We had all 4 slots working before (4x1Gb) and the mod seemed to seemed to go real well.
Now we can't get it to boot with anything in slot 1 or 2 - 3 and 4 are working fine though ?
So, bios B03 or B04 for a Q6600 and 4x1GB D9GMH?
have you tried clearing CMOS with battery out for a while?Quote:

Thank you very much for the suggestions - will do the battery thing and double check for warping - all four sticks work fine in 3 and 4 :yepp:Quote:

I just wanted to check what the temps of PWM should be. I also was wondering what PWM is? My temp under full load (prime95 on all four cores) is 93-95c.
I'm also experiencing some random instability under full load and am looking for some help to clear this up.
My voltages are as follows:
CPU: 1.550 BIOS, 1.510-1.520 (CPU-Z 1.43), 1.50-1.520 (uGuru), 1.45v Load
DDR2: 2.225
VTT: 1.42
MCH: 1.74
ICHIO: 1.70
DDR2 Reference: +2%
CPU GTLREF 1-4: 69%
CPU is at 9x400=3.6Ghz
Memory is at 1000Mhz (1:1.25) 5-5-5-15
Any suggestions as to what I'm doing wrong?
very high temps, have you done ace-a-ru heat mode yet!!
edit, heatpipe mod
Yes, I have. I even have a 40mm fan strapped to the heatsink (Not the SB or NB, so I assume it's the PWM?).
yes the temps are high, have you try ace-a-ru heatpipe mod it works great!!
sorry d post
ye you need to 40mm on the PWM
mine fully loaded is about 58c.
sb not to bad nb yes!!!
Thanks scorpion. When I look for CPUID I am sent to the CPU-Z website.Quote:

Good suggestion for the program. I really like it!. My max PWM Load temp is 58, NO fans or anything. Thats with my highest OC of 4.3mhz. With stock Load is about 48Quote:

Is that your PWM @ 48 celcius or your CPU? My PWM is @ 45 celcius when idling. I havent done any tests yet because I will have new ram in a few days so I can start overclocking properly and testing then. I still havent gotten an answer to my CPU temps though.Quote:

since it controls the power to the processor, hence, you have heat produced and in need to be monitored by temperature sensor...the only thing abit didn't do with this particular board is to add the amps that it uses during idle or load...it does for the digital PWM's that are on the AB9 QuadGT and the IX38 QuadGT.Quote:

No official thread for us IP35-E users?? :down: :down: :down: :down:
Anyway im currently using a IP35-E and im wondering on the following
Currently im overclocking at 3.2Ghz ( 400FSB & 1.315vcore in bios , all other voltages are left in stock )
My windows idle vcore is 1.280 and loads at 1.232 ( about a week ago it was at 1.240 ) during full load my PWM temps shoot as high as 70c with a decent fan blowing over it.
are the above values pretty normal ?
Is there a particular voltage that goes to them PWM that we adjust and control?Quote:

oh! the bios is version 14
did anybody reset uguru as written on abit website? (Turn ON your PC with our µGuru™ motherboard and then turn OFF right away as one single action; repeat this action continuously for 3 times.)

I have a Q6600. I am after flashing both 16 beta 03 and beta 04 to my motherboard and the motherboard came with bios 14 installed. I was trying to look for voltage options and in the original bios in UGURU I was looking through the voltage options. In Beta 03 I found a few more options than there was in the other bioses. I have an option for DDR offset and another voltage setting (that I cant rember) has a few more voltage options also.Quote:

I'm 95% sure it's the uGuru one, expecially since the Core Temp says something about a Tjunct max of 100C (but shouldn't it be 86C?).
Just have to say that im LOVING this board. Beats the hell out of my POS 680i. I wasnt able to get over 2.7 stable, im now at 3.6 4 hours prime and still going strong.

Already done that but thanks for trying man :). Ive got it to boot into windows @ 3.9ghz but had to bump the CPU voltage to 1.7ghz to get it there. I am now @ 3.8ghz but it still requires 1.6050v to boot into windows and run 3dmark 06 without rebooting or freezing on me. I have my ram settings set to auto with voltage set to its reference 2.3v (its written n the ram 2.3v). Windows wont boot up with the voltage on the ram any lower.

Thnak you illidan and th3joker for your help :up:
Hi all just a quick question about if this motherboard will support running 4gb of ram @ 1066 as it only shows as supporting 800mhz in the spec`s. I thought maybe a bios update would sort this out and if so what is the best bios to use 14? any advice is welcome..
Cheers Paul
Yes 1066mhz ram is supported. To make your ram run at that speed you will have to set it up in the uguru area in the bios via ram divider.
i'd say that you are doing very well if you are getting close to 1225 mhz memory speed...if you had a bios like DFI's which has many, many bios tweaks for memory settings, you would probably do better...BUT...1225 is nothing to sneeze at!;)Quote:

Never came back from that, so the next day I went back to Microcenter and exchanged for the IP35 Pro, I have much higher hopes for this board. (Maybe at least a year or two...)
Anyways, I've done lots of overclocking on the AMD side of things, but I haven't had an Intel to overclock since the Celeron 300A days.
I'm wondering what people's experiences have been with the 16 beta bios and the E8400s on the IP35 Pro? I am currently running the 14 BIOS and even though the bios reports CPU temps wrong, other applications are able to report it correctly.
I am going for a mild 4ghz overclock with this CPU and it seems to take a bit of voltage to get it there. Setting 1.5250 in the BIOS gives me a 1.44 at idle in windows, 1.40 under full load. Is the beta 16 bios any better at attaining stability while overclocking the 45nm cpus? Also, can I be sure the voltages I am seeing currently are accurate on the VCore, anyone compared between the 14 and 16B03 / 16B04 bioses?
I am just a little hesitant to flash the latest bios because of a few problems I've heard here and there with regards to memory compatibility and the memory I've got is NOT good overclocking memory. Bought it because for $75 at a store 4GB is tough to ignore, and besides I just want 4ghz and leave it at that.
I have a few questions on voltages, was wondering what the ideal voltages would be for this E8400 with a FSB of 446? I currently have the following voltages:
VCore = 1.5250 bios ~1.45 idle - 1.41 load
MCH = 1.25 bios ~ 1.26-1.27 idle/load
CPU VTT = 1.23 bios ~ 1.25 idle/load
ICH = 1.12 bios ~ 1.14 idle/load
ICHIO = 1.50 bios ~ 1.53 idle/load
CPU GTLREF 0&2 = 59%
CPU GTLREF 1&3 = 60%
DDR2 REF = +2%
DDR2 = 2.100 ~ 2.10 load/idle
I was wondering what CPU GTLREF is ideal for this CPU and the IP35 Pro? I can get my CPU stable (Orthos blend for 8+ hours) by giving it more voltage, but right now CPU-Z is reporting 1.45 when idle, and 1.41 under load. If under load the cpu starts getting into the 1.40 range orthos will fail.
When I raise the CPU VTT voltage it seems to actually drop .01 V on the VCore, so I have stuck with 1.23. Not sure why that is, but perhaps someone can shed some light on that.
First post here so go easy on me, I'm not a noob to this at all, just refreshing on the Intel side of things. Thanks in advance for any help!
Edited to add:
Also figured I'd throw in my VID: 1.0375
Ouch, that sounds a little high, I would check it to make sure the heatsink is making good contact with the PWM surfaces, it sounds like it may not be contacting everything. My PWM temps never go above 50C, normally at idle they're around 42-44. I haven't done the bolt mod or even removed the heatpipe at all yet, didn't see the need as my temps weren't getting real high.Quote:

well your processor doesn't draw anywhere near the power his draws. But even then it is quite hot I only got near 90C when I had no fan on the pwms with no bolt mod. What kind of fan do you have on it and where is it positioned? I kept mine cool running a Q6600 by strapping a 75CFm 80mm fan angled straight at it so the air couldn't go anywhere but on the heatsink.Quote:

Thanks for pointing that out silverphoenix... I was about to panic about my temps. I think they are so high because I'm pushing 1.5650v (BIOS setting, windows in 1.50-1.52) throught the CPU. I think I'm just going to accept the fact that 3.6Ghz is not attainable and try 3.5Ghz... /cry /cry /cry
someone here tested the abit IP35 with an 8400??
i ordered just a new abit and an 8400, hopefully everything works fine...
Whoops, very true, a 65nm quad core is going to draw much more current then a 45nm dual.
Mystic: I'm using a IP35 Pro and all has been good here so far.
This is the same system squito posted on earlier in this thread. DIMM Slots 1 & 2 are completely dead, so dual channel is out of the question. We did the bios update, loosened up some of the bolts, pretty sure like Ace said it was a cold sodder joint and doing the heatpipe mod did the job on it. However, I was able to acheive this out of it.
http://www.syntaxdesigns.net/xs/9x475-1.45vcore.jpg
Memory is G.Skill 2x2GB F2-8000CL5D-4GBPQ. It has been stable for 24/7 for 4 days. However, to do 32m superpi or prime95 I had to crank the voltage, and it would still crash, so I gave up on that. I put it back to stock today because my replacement Commando is coming in a few days and after seeing the results some people are getting with them I am excited. We will be sending back this board and getting another ip35pro. Before this e8400 I had a xeon 3060 and 4x1gb crucial pc6400 and it ran 3.6ghz/ddr1000 no problem, it's definitely a good board choice.
**EDIT**
Here's my VID
http://www.syntaxdesigns.net/xs/vid.jpg
Anyone here aware of an app that will let you change the multiplier and vcore from the command line? I've tried CrystalCPUID 4.14.2.404 and that does allow me to change the FID and VID from within the application itself from the Intel Speedstep menu, but if I try to do it by passing it on the command line, it is ignored and not set.
I'd like to setup rivatuner to bring my VID and multiplier down when CPU usage is low, just seems that finding a command line application to do so is not easy.
heh guys...How high are people generally gettin on the FSB with Dual Cores?
Here's my results last time, working on lowering voltages now:
http://img89.imageshack.us/img89/630...7082343gv1.jpg
I know my overclock isn't as high as others, but really 4ghz is more then enough for what I need it for and I felt this should be a safe overclock on an air cooled system. I did let that orthos run out to 8 hours before I rebooted and brought voltages down, just forgot to get a snapshot of it.
I cant even get my quad core to a stable 3.6ghz on this motherboard. My settinga are
VCore 1.55v
MCH 1.37
CPU VTT 1.31
ICH 1.09
ICHIO 1.55
The more voltage I put into the CPU the more it gets stable but the consequence of that is extreme heat.
few little bugs, nothing majorQuote:

You might try a little more voltage on the MCH. At least on my board, when I up the voltage cpu temps and pwm temps seem to go down, also the 3.3 and 5V rails seem to go up. Odd but I'm still playing with uguru and watching my volts / temps to see what affects what. FWIW my MCH is set at 1.41 and is being reported at 1.42, and I'm running 4GB of ram. I have had my MCH as high as 1.56 and all it seemed to do was create heat for me.
