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

[nimrod_o]

Hello there.

I need some help regarding the mosfets.
I am running the IP-35(not the pro version) and i am about to install the MIPS water cooling block on the mosfets.
As expected when I took the original heatsink off I found the "Cover sheet" over the mosfets.
The question is:
Do I keep it and just mount my water block on top of it?
Or do I put it aside, apply ceramic paster on each mosfet and then mount my MIPS Mosfet cooling block?
By the way what was the function of this "Cover sheet" in the first place?

Answers will be greatly appreciated.

click on the 2nd link to see suggestions...plastic ties work well.

I have exhaustively studied the pics in those links, I see how you did the NB(sort of), but I can't really see where the tie placement is on the PWM.

thanx,
h

look at the red arrows...tied on to the heatpipes of the TRUE 120.

AHA!!

I have a TT Big typhoon so this should be interesting...

I have collected the following for my heatpipe mod extravaganzzzza

2 Silverstone FM121 120mm 110CFM fans
2 40mm 8.5CFM fans
1 AS ceramique(for the PWM, NB, GPU/GPU RAM)
1 AS 5(for obvious reason )
1 6 pack of Guinness

I still have to get lapping material(s) and the nuts, bolts, and galvanized rubber standoffs.

Thanx Ace

Easy there, you want this mod to really work.

Lol, always enjoy in moderation

[h@RRy]

On another level, is 8.5CFM for the 40mm's enough?

[JoeBar]

More than enough. @ what rpm's?

[Ace-a-Rue]

Right, I'll give it a shot. What's the newest stable bios? Beta or retail, doesn't matter.

i am using 16.B01 beta bios...works very well.

I'm doing 3546MHz on my new Q6600 G0 under water at 1.475v in BIOS v. 14, and I get Prime errors at this speed. Shouldn't I could go higher with this voltage on a G0? My RAM is on a divider atm, so it's not them, and I haven't touched anything besides the vcore, but I tried to lower the multiplier, and then the Prime errors disappear, so it's gotta be the CPU, right?

vcore, MCH, ICHIO 1.5, Vdimm and memory ratio all play a role in P95 when you get higher in Mhz range like 3.7 to 3.8...good idea to set 1:1 memory ratio...most likely you will only need to raise vcore at 3546 Mhz.

[Alaza]

Well it's not my RAM at the moment, so I'm guessing it can only be vcore and MCH that can change anything?

By the way: What temperature sensors should I trust? SiSoft Sandra shows something like 40C load and CoreTemp shows 60-65C.

[Ace-a-Rue]

core temp is accurate when P95

If it helps, I just put my sys together in my sig last night and have been stressing close to 24hrs on the smp folding client once I passed an hr of occt.
3420@1.4v bios 14...
I'm on air(extreme 120/mx-2)...
maybe try backing down a little 50-100mhz...

[atlr]

It seems like uguru 1.05 is mixing up the temperatures.

abit eq in uguru 1.05 running in XP on a ip35 pro PCB 1.1 bios 14 does not show accurate temperatures; the values seem mis-assigned.
For example, abit eq shows
CPU 25 C
System 29 C
PWM 36 C

However, I measure ambient in the case of 25 C with a thermometer and the utility coretemp shows CPU temps of 36 C.

The negative effect is that FanEQ is getting the wrong temperature and the CPU fan is not speeding up when it should which is causing system instability.

For now, I dropped the FanEQ min temp to 25 C and its 100% fan temp to 32 C. I must say the Intel stock heatsink is quiet and seems sufficient to overclock a X3220 to 3 GHZ.

Hello,

I'm new here and could use some help . I am currently at 3.6 gigahertz. Heres what im working with....

q6600 go
abit ip35pro
thermalright ultra120 extreme with 120mm fan i beleive, as5 paste
ip35 bolt mod
g.skill 2 gigs ddr2800 pc6400 hz found here
http://www.newegg.com/Product/Produc...ting=-1&Page=2

heres my settings now 400x9@3.6
dram is 1.1 divider
pci clock is 100 mhz do you guys overclock that?
cpu= 1.4425
ddr=2.1
ddrvtt=1.23
cpuvtt=1.23
mch=1.37
ich=default
ichio=default
ddr ref 0%
gtl=67%
pcieclock=100mhz

any recommendations on the above settings.changes that would help? the volts are prolly higer than they need to be i just put them at suggested max.
where can i find the voltage settings for the nb?

temps read by core temp are 33 celcius,abit iq shows 21celcius system temp 30 and pwm 41celcius
im using bios and uguru that came with mainboard.

my question is memory, should i go with tighter timings for gaming or higher bandwith since this is an intel proc? i had my ddr2 800 running solid at around 1100. i might be able to hit 1200 but what is better for me timings or bandwith? should i try for 1100 with 4-4-4-9 and up the voltage or something like that?
when i see the memory speed i.e. ddr960 is that doubled with ddr2?

also can you help suggest memory speeds,ratios,timings etc for peak performance? thank you guys

[Ace-a-Rue]

don't worry over the difference between coretemp and uguru...it is what is.

ddr1100 is an excellent speed...just play with the sub-timings to see what it can give you....you can try P95 but it puts max stress on your system which most likely require you to, at least, boost your vcore...if you do 30 minutes or 60 minutes of P95, you should feel good about that.

the NB voltage is controlled by your ICHIO 1.5v setting.

PCIe clock will gain you some performance boost from your hard drive and your VC...i recommend not going above 110 Mhz..if you go above 120 Mhz, the intel controller will drop offline.

memory ratios to strap settings are like what is depicted in this image.

"memory ratios to strap settings are like what is depicted in this image."


What is that statement based on?

[SHAIDO7]

man just passed 30 minutes of prime95 at 3.8 hmm do i need to run two p95s at same time?

Not if you use v25.4 or Orthos

are you not understanding what is depicted in that image?...this is how abit has the NB coded to set memory straps according to FSB to memory ratio that you select in the bios...i can only work off 1:1 at my 480 FSB...if i lower the FSB, i can jump up to 1:1.2 ratio....some memory like crucial can work at the 1066 strap...mine can not

[stuck]

This is my result of the first day of OC session

Mobo: Abit IP35 Pro
CPU: c2d e6750@4040mhz (505x8) vcore: 1.60
Mem: 1010@4-4-4-4-2T@2.2V
Cooler: Thermaltake Big Typhoon VX

A Little Question: Who is the best rev of BIOS for this mobo?, thanks...

[SHAIDO7]

Hey ace,
the forum mod at abit is named master of none im not sure if its the same person.

btw running at 3.8 on air i know i can go further but 3.8 is good enough for me. I n prime 95 my temps were about 60-62c for core0 for a brief second under 60 for the rest of the cores and pwn went up to 66. are these temps acceptable or are the to high? when im just doing basic tasks the temps are cpu 30-40c and pwm is 53c. the game bioshock crashed on me once and since that happended im wondering if vdroop is the problem and if i should increase the voltage a tiny bit more for the cpu or if maybe the ram was the culprit im not sure since i didnt get any bsod or errors. what do you guys think?
im at these voltages now
cpu volt 1.5525
mch 1.48
cpuvtt 1.23
ich 105
ddr 2.2
ichio 1.55

Well I think I understand what is depicted in that image. And indeed, for the most part the color coding you added matches the N/B Straps and their memory ratios from the Intel 975X chipset. However, note with the Intel 975X chipset the 1:1 memory ratio is available in three different N/B Straps. The IP35 series doesn’t have N/B Strap information in the BIOS. So how do you know selecting the 1:1 memory ratio invokes the PSB1333 N/B Strap and not the native strap based on the processor? For that matter how do you know selecting any memory ratio invokes a particular N/B Strap? I’ll add I tend to agree with you, I’m not trying to be a smart ass. I just want to know, as I asked in the first post, what do you base that statement on? Did you deduce it? Did you read it in an Intel white paper?


Abit AW9D Max N/B Straps and Memory Ratios
PSB533 N/B Strap
DDR2 400 = 2:3
DDR2 533 = 1:2

PSB800 N/B Strap
DDR2 400 = 1:1
DDR2 533 = 3:4
DDR2 667 = 3:5
DDR2 800 = 1:2

PSP1066 N/B Strap
DDR2 400 = 4:3
DDR2 533 = 1:1
DDR2 667 = 4:5
DDR2 800 = 2:3

PSB1333 N/B Strap
DDR2 400 = 5:3
DDR2 533 = 5:4
DDR2 667 = 1:1


Yes, I am a Mod at Abit forums. Ace-a-Rue should be aware of that. That should have nothing to do with my question(s). I know it doesn't for me.

Hey master,
I was just trying to let ace know you are very knowledgeable when it comes to abit motherboards thats all.I was only trying to help
