Abit IP35 Pro - VMod needed

[andyddr]

Can someone point me in the direction of a vmod for this boards please.

[bassie]

What kind of vmod? Vcore, vdroop, vdimm, vmch etc.

It would be easier for us to help if you show us some pics.

[andyddr]

I'm new to the Vmodding scene so anything for me to study and research while I'm waiting for my board will be appreciated. Particularly concerned about Vdroop at the moment.

Any hints welcome too.

[Johnny Bravo]

I'll need to know what all is needed. The board already has a good voltage range on most settings, the vdroop is not that big a problem though

[andyddr]

System specs will be:

E6850
Thermalright Ultra-120 Extreme
Abit IE35 Pro
2x1GB Crucial Ballistix Tracer PC8500
2xSeagate Bara 7200.10 320G
MSI GeForce 8800 Ultra
1200 TT ToughPower 1200W

I've looked around but haven't seen any information of what the max selectable bios voltage is for mem or cpu. My Tracers like voltage (2.6v) and I'm a little concerned about what the board can offer. Your review shows some fantastic numbers (thanks) but I'm going to need more than 515MHz. The order of 550MHz will be needed (seen a 610 vmodded shot on these forums) assuming my E6850 will be able to run that high.

Missed it. Just re-read your review and see you've set all voltages to max in the bios to show us what the board offers. Duh. So mem is not a problem, 3v should do it

So I guess all I really need here is a way to get a higher FSB.

mine was limited buy the cpu, I've got a e6850 in post will keep you posted about it

JB is right...chances are you are going to be limited by CPU and not the board. my E6600 is a decent FSB CPU that is prime stable at 550FSB and benchable at 560FSB in a P5B-Dlx with air cooling on the CPU. i have only had the IP35 Pro running for a day and have had no problem getting prime stable at 550FSB already, on stock cooling right out of the box.

all voltages are at the lowest except vMCH (1.56v set in BIOS). here is a screenshot of a quick 550*6 Orthos blend run at an hour:



performance level is 8 and i haven't tried anything higher than 515FSB at PL7 (vMCH 1.46v).

[andyddr]

Thanks 3oh6, that's what I had hoped to hear. Seems CPU's are the limiting factor for high FSB. Anyone happen to know a CPU FSB wall hack

All @ lowest voltage...Now I know I bought the right board.

Looking forward to your post Johnny, give us the steppings too please. These little E6850's are still a mystery to me.

except vMCH, which needs small bumps as you raise the FSB. the biggest thing to remember is that the memory divider sets the MCH strap and the PL (perfomance level). overclocking this board is a bit of a juggling act, but once you figure out what does what...its nice to work with.

keep in mind this is just 1 board though so YMMV but i have had a few P5B-Dlxs all of which would clock as high as the CPU would and seen many other IP35 Pro users with high FSBs. as long as there is a 1333 strap, the P965 and P35 chipset boards should all have no problems clocking well over 500FSB as long as the CPU doesn't have a wall.

And that folks is what makes overclocking an art

[Nosfer@tu]

Still would like to have the Vmods

[Johnny Bravo]

Enjoy!

nice johnny!

i'm having some major droop issues with my board.

argh. wonder if this will help.

just curious, how did you find this?

[Johnny Bravo]

a datasheet, a multimeter and a degree in electrical and mechanical engineering

[shimmishim]

a datasheet, a multimeter and a degree in electrical and mechanical engineering

lol that's good enough for me!

i think i will mod my board today.

i wonder if droop is chip dependent as well.

i have a new e6600 that is causing the board to droop almost 0.09 volts!

the e6700 i had droop about 0.07.

yeah. i'm gonna hope the droop mod works out.

i have faith it will.

also, would you suggest setting it to 1K and turning it down or setting it directly to 620 - 650 ohm before soldering it on?

[zbogorgon]

anyone got vcore ? 1.85V is not enough for LN2

[zbogorgon]

hey, I am serious about vcore, it's a MUST, I need at least 1.96V for LN2 !!!

[Nosfer@tu]

Take some pictures ofthe board?
Find some some of the PLL sheets or somthing
make the work load smaller for the Electoron ninjaes and they will aid you

[Johnny Bravo]

I think I have it tho will need to setup the board again to actually test - bare with me should have something up in 24 hours.

[zbogorgon]

I got a hint that it should be pin4 to GND, I measured resistence and it's 1062 Ohms, the only thing i need to measure where it's connected.



NOT TESTED !!!!

[MikalCarbine]

Has anyone tried the vdroop mod yet?

I'd recommend you don't do that just yet - the AW9D had the same controller and hipro5 went off on Hicookie for suggesting the same mod. The feedback isn't as straight forward as that.

[MikalCarbine]

I have

Sweet, did you notice any greater stability with the mod, or does it just fix the vdroop?

I'm new with these Intel boards, could you please explain MCH strap and PL to me? Would one achieve higher performance running 1:1?

[MADMAX22]

Just for fsb limits of the board I have my E6600 which is fsb walled at 540, this baord got it there with no issues and only 1.44vmch. I tried a multitude of other combos to get the cpu over its wall and only got it to post once at 545 with this baord but it crashed.

The board is golden for fsb just needs the right cpu.

[MikalCarbine]

Does anyone know the vcore measurement point? I want to do this mod tonight but I don't want to rely on software to tell me how well it's working
