IS7 vs IC7

[deltarealm]

Looking at pictures of the Abit IS7 motherboard, the cpu mosfet's look large!
I terms of PWM handling, would the IS7 be as strong as the Abit IC7?
Would the IS7 be good for high current draw, voltage and highend overclocks?

I have ic7, for good oc you will be need to do volt mods cause in bios max vdimm is 2.8v :\

i think that P4P800 batter thank IS7

Thats a good picture! Those mosfet's look large. Would it be better than an Abit AI7 for overclock if the IS7 is modded. In the picture the IS7 PWM looks strong. Is the IS7-E the same around the cpu area?

IS7 = real cheap, tight budget, if make a mistake modding, not out of pocket.

I don't need any extra features, e.g. raid, gigabyte lan.

Someone tells me the very last of the IS7 that are being sold new, have the lastest model vertical fan/heatsink northbridge cooler, like on the AS8, is that true?

btw. I hope the PAT feature is not locked out on the newer IS7 boards? What is an IS7-E2?

What is an IS7-E2

Stripped down version of the board. About 2 inches slimmer and only has 2 dimm slots. Do not confuse this board with the other IS7's :)

Yea your right I checked the Abit web site. ekk!

Found an IS7-E with the round finned heatsink.

It appears that the PWM setup looks a hell of alot beefer than the AI7.
Would the IS7-E be better than the AI7 for BIG overclocking, and handling prescotts, once Vdimm modded, and the Vdroop mod?

i think that you are need P4P800 ... it is batter than ai7/is7 for big OC

I would go with the Ic7. I owned a P4P800 which stopped at 250x12, my friend had the same results with the combo. Then I bought him an IC7 and he went upto 275x12 or so on air.

I've had an IC7/3.0C combo on air. It did around 240x15 stable. Then I did many upgrades like a power supply, SP94, and other things, at the same time as switching to an IC7-Max3 and got 250x15 stable on air with a northwood.

IC7s are only around $60 used. If I had to do it again, I'd get the IC7 over the IS7 or the AI7. But it's true, you only get like 2.8v on the RAM, but that was never a problem for me. The Max3 gives you 3.2v,however there are issues concerning that.

My IC7 did 240x14 stable to, but it pass all bench's on 245x14
my 2.8c bad and bad memory

2.8v it will be no problem for ppl with TCCD chips

Go P4P800SE. Not so cheap but can be PAT modded (with the P4P8X and P4P800 BIOS trick from abxzone and don't forget to set FSB133 and RAM at 266 before each reflash), it worked with full PAT on upto 280MHz for me (1:1, TCC5 mem), but my CPU is bad. You also need a droop mod. With AI7 I couldn't go past 255 with same CPU/mem combo either at PSB533 or 667 (PAT on). Memory performance is better than ABIT IC7-G's.

Hi there,
I have an IC7, and I'm currently running a P4 2.8 @ 257fsb, completely stable (1.62v) on air. I have NEVER had a board as good as this tbh, I'm going to dread getting rid of it when it comes to upgrading :-(
