IS7 vs. IC7: The true story, stock vs. overclocked

Ok, so we've all been seeing the glowing reviews on first the P4P800, and then the IS7, with it's beta BIOS, matching or even beating the various Canterwood boards. I'd played with all of them, and knew that they didn't quite hold up when overclocking, but I wanted to put the numbers to it.

So...I took an IS7, with the latest beta BIOS (IS7_G13b4), and pitted it against the IC7 with the latest beta BIOS (IC7_025). These BIOS's are really comparable (both have the Gaming Acceleration options of Auto, Turbo, Street Racer, and F1).

I used the same hardware (exact same pieces) for both: 2.4C, 2x256 Kingston HyperX PC3500, Ti4200, XP Pro, no sound enabled, all the latest updates and drivers.

To start off with, I just ran Sandras, to get an idea what was happening. Both boards gave identical CPU-Z results at the same settings, which makes everything pretty easy....

1:1 Ratio
Auto/By SPD 2.5/3/3/8
200.5x12=2406
IS7- 4397/4408 | IC7- 4805/4681

...your typical big 875P/865PE difference. I will note that the new BIOS for the IC7 raised the bar quite nicely. Let's crank up the timings...

Auto/ 2/2/2/5
200.5x12=2406
IS7- 4506/4499 | IC7- 4862/4794

...gains by both. Nothing major from the timings, as we've come to expect from the 865PE/875P chipsets. Now let's crank up the 'gaming acceleration'...

F1/ 2/2/2/5
200.5x12=2406
IS7- 4992/4971 | IC7- 4923/4926

...shazam! IC7 actually gained (kinda surprised me), but the IS7 does what you've seen in all the reviews...jumps up past the IC7 in Sandra. Pretty dang cool, really.

Now, though, let's get to the heart of the problem: using the 5:4 ratio to overclock...

5:4 Ratio
Auto/ 2/2/2/5
200.5x12=2406
IS7- 4342/4341 | IC7- 4473/4450

...this is again pretty typical 865PE vs. 875P performance. Now let's F1 that sucker...

F1/ 2/2/2/5
200.5x12=2406
IS7- 4432/4434 | IC7- would not run

...right away, F1 will not run on the IC7. In fact, neither will street racer or turbo. Anything but Auto won't boot. However, notice now that the IS7, even with F1 acceleration, cannot beat the IC7 with zero acceleration. F1 gave the 865PE less than 100 points in either Sandra at 5:4, where it gave nearly 500 points at 1:1...in essence, losing the majority of it's 'PAT' boost (this is not really PAT, folks).

Now that we know what to expect, let's put a couple benchmarks to it:

IS7 1:1
F1/ 2/2/2/5
200.5x12=2406
Sandra- 4992/4971
QIII- 434.5
Comanche- 53.13
3DMark2K1- 12824

IC7 1:1
F1/ 2/2/2/5
200.5x12=2406
Sandra- 4932/4938
QIII- 434.6
Comanche- 53.56
3DMark2K1- 12781

So there they are at stock 200, 1:1, F1 acceleration. First, kudos to Abit on both new BIOS's...they brought nice gains (even outside of the acceleration stuff, really). As for the scores...nearly identical. IC7 takes QIII and Comanche, IS7 takes Sandra and 3DMark, and none of those differences amount to a hill of beans. Still, quite impressive what they've done with an 865PE, at least at stock. Now, 250 at 5:4...

IS7 5:4
Street Racer/ 2/2/2/5
250.6x12=3007
Sandra- 5477/5511
QIII- 494.7
Comanche- 61.40
3DMark2K1- 13768

IC7 5:4
Auto/ 2/2/2/5
250.6x12=3007
Sandra- 5515/5557
QIII- 510.1
Comanche- 63.54
3DMark2K1- 13867

Street Racer is the best the IS7 could pull off at 250 FSB. In fact, all those settings basically start melting away the higher you go in FSB...Street Racer quit working around 260, Turbo died off at 265. Again, though, even F1 didn't do a whole lot at 5:4, but it's worth noting.
Still and yet, the IC7 beats the IS7 by roughly 3% in QIII and Comanche, and 1% in 3DMark (the Ti4200 is really holding back any differences there). And that's the IC7 with no acceleration, IS7 at Street Racer. Those differences will widen slightly the higher you go, as you have to drop the acceleration settings (this is why I don't really care about the IC7's lack of acceleration, either...you won't be able to use them at high FSB's anyway).
This is the almost the exact same thing macci found comparing the P4C to the P4P...he noted that he needed more that 300 FSB at 5:4 on the P4P to beat his P4C800 at 300 3:2 (the drop from 5:4 to 3:2 is roughly 2.85%, so it's right on par).

Well, that's it in a nutshell...the 'PAT' 865PE's basically revert back to normal 865PE operation once you drop down to 5:4 and start overclocking. You'll basically see 3-5% differences between the two, scaling upwards as you go higher in FSB and have to dump acceleration (which doesn't matter to much with 5:4 to begin with).

I liken this debate now to the memory decision. If you're at stock speed, just go with whatever. If you're going to overclock, spend the money, and get good memory. Same with the motherboards...if at stock, it doesn't really matter, but if overclocking, spend the money on the 875P.
However, the difference between the IC7 and IS7 is only $27 currently, where good memory would cost you a lot more than that.

Sooo...I'd say just go with the IC7, and take one less worry out of your life.

That's my report for the week...have a good weekend.
Cheers ;)

Very nice Zroc...:)

Would u agree that the results would have been in the favour of the IS7 moreso if the IC7 didnt get this new recent bios also?

This comparison has made me tempted to update to the IC7 but I like having the LAN on the IS7....and its a top mobo :) Im just dont want to fork over the cash for the -IC7-G when I wont use the extra features besides the LAN....maybe I should just go the IC7 vanilla and use a NIC :)


Again, nice comparison and you too enjoy your weekend :D

Top stuff, as always Zroc! Excellent findings! :)

Creat: Just go a 4PCA3+, 875 with lan and volts for the same price as the IC7... hehehe ;)

IC7 looks like a winner, but the price performance ratio has to be better on the IS7 than IC7, wouldn't you think Zroc? I mean, the IS7 @ $109 vs. the IC7 at $140, for the average overclocker the IS7 would perform very well.

Thanks fellas ;)

Creative: Nah, if one already has an IS7, I wouldn't get an IC7 just to get that 3-5% in general. Some would, naturally...or if you could sell off your IS7 for the same price your got it, sure.
Heh, I figured most people had NIC's lying around...ah well, they're $10. IC7-G is really only worth it if you use gigabit lan or want to run more than two hard drives.

Of course, I'd get the IC7 just for the looks...I have a window, and the IS7 is kinda ugly, imo ;)

jaawood: Price/performance? Tough call...at major distro, the difference is less ($26 difference), which will translate if you look hard enough. Still, that's 20% more for 3-5% performance, so you could definitely say IS7 is a good bang-for-the-buck deal.
FWIW, I think the IC7 has a nicer package (rounded cables and stuff that matches the board).
Still, people spend a LOT more than $20-30 on memory or power supplies and such to try to get 3-5%...so in that sense, I think the 875P chipset is worth it. See? It goes both ways...

Bah...I'll toss out the facts, and let ya'll handle the decisions ;)

good point about the looks - that is an important point i hadn't considered. i see your point about the cost/performance ratio for the mobos and other hardware as well. i guess i should say that for me the IS7 would be shweet because i could get a nice overclock, but i wouldn't be at the top of the 3D mark charts. the IC7 could take you there:banana:

Zroc thanks for the reply :)

Ive got a 3com nic lieing around so thats ok.....but as you said I dont really know if the upgrade would be justified. Id only get the IC7 vanilla so maybe the $75AUD it would cost after selling board to upgrade might be worth it?

Im a 3dmarker and if the IC7 is scoring ~350 points more then Im all for it!! :banana:
heheheh

nice article and comparison. well done.

;)

its proved and proved again that canterwood beats sprindale at higher fsb's

well done zroc.

can you do unbuffered benches next time :D

Greta job Zroc! I'm gonna be linking this thread all over the net. This is exactly what I've been trying to tell other folks I'd seen happening, but no one had put it together concisely...until now:)

I think I'd have to rate the IS7 as the bang for the buck champ....that's just my opinion. For those on a strict budget, it's definitely the board to get. For those crazies (like us :) ) who spare little expense to have the absolute best, the IC7 is the way to go.

Side note...thumbs up to Abit for tweaking out these boards!:banana:

but didn't prom say the sprindale overclocked a little more, matching the performance of canterwood.

heres the thing...IS7 + OCZ Gold = Winner...Why? Because right now I can run IS7 at 255 FSB 1:1 (2.5.5.3.3) without problems. And that's not even using the beta bios. Doing these numbers on the beta bios in say F1 I can get some crazy sandra scores. Oh and the "Gigabit" Lan on my IS7 is nice too ^_^

Zroc, nice comparison - except for one thing. You didn't test which one could get the best scores topend period. If the 2 boards are that close at the same settings...what if you could get a better fsb oc on the IS7 than the IC7? I liken this to testing memory at top end with tight timings vs. top end with looser timings (allowing higher speed) and seeing which comes out on top.

Again, nice article, but could you do a little further testing and add which can do the best topend fsb (ie., forget keeping them at the same settings)? I know this makes it harder because all sorts of variables potentially now come into play, but I'm still interesting in seeing it.

EDIT: And believe it to be very relevant to the "which one to buy" question.

EDIT #2: As is rightly pointed out below by Alexandrus, if you are cpu limited, this is info all you need to make your decision. So the additional testing I've asked Zroc to do is only relevant if you are not cpu (or memory for that matter) limited. Forgot I'm not in AMD land (with changeable multis) anymore ;) But I'd still like to see a top end comparison where the neither the cpu nor the memory is the limiting factor.

well done

Good to know, because I was really tempted to go out an buy an IS7-G or 4PDA+ over IC7-G or 4PCA3+, but now I know not to do that. Thanks.

This is exactly what I'm talking about in my post above...I don't think you do know not to do that yet...because it's still possible that you can overclock the FSB higher on the IS7 than the IC7 and get equal or better overall performance for less money even though clock-for-clock the IC7 is better. That's why I've asked Zroc to test that.

Yes, could be, but I don't care because I already know the max potential of my CPU, and I won't reach the limmits of the mobo ;)

Ok, if you already know you're cpu limited, that's another story. In that case, going for the mobo with the best clock-for-clock performance makes perfect sense.

good review, thanks.

This is good info, but there is more to this than meets the eye! ZroC himself said "The performance boost goes away when you switch to 5:4" but what if you dont have to?

What if I have ram(OCZ PC3700 GOLD) That does 266FSB and a P4 3.0C that clocks in at 4GHZ in a Prometeia

In this situation running 1:1 would the IS7 still beat the IC7 because of the F1 settings? Since its apparent you only lose the edge when you use the memory dividers

Thanks guys:

@oplix: see, in your specific case, I would think you'd DEFINITELY want the IC7. Looks at the tremendous differences between the IC7 and the IS7 without acceleration.
And here's the thing: ANY acceleration on the IS7 does NOT work if you choose CAS 2.5. No other settings affect it, but if you choose CAS Latency 2.5, even at stock 200 FSB, F1, Street Racer, or even Turbo will NOT boot.
At 1:1, that's a HUGE deal for the IS7 (all timings 2/2/2/5):
F1- 4992/4871
Street Racer- 4912/4924
Turbo- 4903/4932
Auto- 4506/4499

As you can see, it's the Acceleration period at 1:1 that gives the IS7 it's kick. There's a 400 point difference between Auto and Turbo, and less than 100 between Turbo and F1.

So take that into consideration, folks...at whatever point your memory stops working at CAS Latency 2, so will Acceleration, which is the main thing that gives the 865PE it's 'kick'.

@Brainstorm: I understand, but that's not the point I was trying to make with this little write up. Max overclock varies WAY too much. What will work for me won't necessarily work for you.
The ONLY way to determine which boards would overclock the most is to take at least 10 of each board (more like 50, and from different batches), different memory, different procs, and different cooling. The maximum I could accomplish with MY individual setups would not apply to what anyone else could do.

What I've done here (and what I typically do in ANY of my write ups) is show what will happen to ANYBODY trying the same thing.
It's more of an information thing that applies to everyone.
Understand?

@WildKard: Look at what I told oplix, as it applies. Wherever your memory stops working at CAS 2 is where memory acceleration also stops, because NO acceleration (turbo, street racer, F1) will boot at CAS 2.5. And at 1:1, turning off acceleration on the IS7 is a BIG hit.

even though it might not paint an accurate picture, i would realy like to see the scores at the highest fsb you can get from each.

I cant get past 315 fsb out of mine 3780mhz in my Vapochill, I've got a MCW-50t on my 9700pro, Im waiting on a NB block to see if it will go higher.

I also have a IC7 on the Way.

Anyone haveing any problems getting an IC7 over 300fsb, since the Silicon is supposed to be the cream of the crop over the 865's??

so if i wanted all out oc and preformance (using pelts) which would you suggest i get, the ic7 or is7?

gouda96: I actually tried. The problem is, I could not get the IS7 to complete 3DMark at 2/2/2/5 timings with Street Racer at even 253. And using Street Racer at 252, it failed Prime95, and corrupted my OS (literally corrupted...as in, I could no longer boot to the OS at stock speeds/SPD timings/no acceleration).
And then it corrupted the OS again at 252 2/2/2/5 with Turbo.

This, naturally, is disheartening.
So for me, these Acceleration settings are basically unusable beyond 250. I suspect they'll be unusable for ANYBODY at a high FSB.

Which leaves you with a plain-jane 865PE.

Which brings me to another conclusion: I feel these Acceleration settings are actually dangerous. Getting a hard-corrupted OS is no laughing matter, particularly for those that don't backup/image regularly.

sounds to me like going with the ic7 is my best bet. I can spend the extra $40 so it is no big deal.

thanks zroc, great post!

Man, i just *love* your in depth reviews Zroc! I don't even bother to read 865/875 reviews any more, you can alway sum up the facts professionaly. ;)

One question: are the current IC7's capable of running +300FSB? The one's i've seen all craped out at ~275-285fsb, making the asus a better buy.

I'm not into extreme overclocking anymore. i've broken too much fine hardware, which contradicts the reason why i overclock: to save money... would the IC7 + 2.4C be a good buy for me? I intend to run it 24/7 at 275fsb with h²o cooling.

I have mine at 300, i can get it to 302, but its not stable. This is on air too.

Hmmm... sounds good. :) 300 ok for everyday use? How's your nb cooled?

300 on air... i can't wait to see this under some pelts!!!:D

I put a Zalman passive heat sink in place of the original, and then stuck the fan of the normal hs on it, with as3 of course. Havnt had any problems with it, i think its the memory holding me back, but i shoudnt complain.

that is a nice cheap cooling solution, $5 at svc.com. I plan to get some ocz 3700 gold. that should do the trick :)

Hehe, thanks ;)
Truth be told, I don't know. This is the same 2.4 I used in the roundup in the overclocking section...it's limit is still 271, with hyperthreading on, passing Prime95 for 24 hours, and passing 20 loops of 3DMark.

This is really all I personally care about. I'm NOT that guy that wants to mod the shinznat out of everything to try to top the ORB. I'm that guy that overclocks to get the most for his money, wants it 100% stable...and then go play games ;)

I LOVE the new P4 chipsets...both of them. And I love that Hyperthreading is now for the masses (more important to me than the overclocking).

However, I don't think people have quite adjusted to the over-200 FSB phenomenon. 25 FSB used to be a REALLY big deal. With a 533 part, going from 150 FSB to 175 FSB was a pretty large 16% FSB boost.
Well, that 25 FSB isn't what it used to be. Going from 275 FSB to 300 FSB is only a 9% boost.

As I pointed out in the roundup, P4's gain roughly 18.4% from FSB alone, where clockspeed alone returns 70%. Clockspeed is more important than FSB, by a longshot.

Then there's the other things...the dividers and timings. Say you have to drop timings to hit 300 over 275...well, there's that performance drop. What about dropping from 5:4 to 3:2? That's an instant 2.85% performance drop...if you have to drop to 3:2 to get past 280, you'll have to hit 291 just to get back where you were.

Heh, I'm getting off topic. Maybe I'll do an opinion piece on modern overclocking ;)

Im at 3:2 right now, i tried 5:4 and the highest fbs I could get was 272, when i dropped it to 3:2 I could then crack up the FBS. There really wasn't a drop in preformance for me with the Ratio. When i dropped it (I still have my timings at 2.5/3/3/7) i noticed a big difference in my 3dmark score. Im getting 23k, but when i was at 5:4 i was getting around 21. It was worth it IMHO.

sounds good to me. 3dmark likes higher fsb and proc.

The drop for me (with vid card at stock) in 3DMark2K1 was 2.85% when dropping from 5:4 to 3:2 at the same FSB and timings.
Try it on yours...you should see about the same thing.

That seems pretty minimal. I would have no problem sacrificing 2.85% for a fairly higher clock.

Hrrm, maybee i missread your post. I though you were saying that you would rather the 5:4 ratio at 270, over the 3:2 at 300.

Ahh...yeah, ya did.
To overcome a 2.85% drop in 3DMark that 5:4 to 3:2 gives, you'd need to go from 270 to roughly 278.
300 would be much better (as you already know).

Zroc,

but what is the better Oc'ing board, the IC7 or the P4P800?

Zroc,
Excellent work AGAIN!
Here's my angle...I'll be using 3.0C or 3.2C (next week)
I'm trying to look into the crystal ball and see what the 16 multi brings to the table. Like 250fsb = 4gHz good. Now if it clocks with subzero cooling to like 270-ish, that's 4300+...first page ORB potential with 540/410. So 270fsb is ddr540 at 1:1...probably only do-able with ocz gold at lousy timings...or ddr432 at cas2, 5,2,2 with some good ram. What's your opinion bringing the 3.2 into the picture? I just sold my IC7 to get a P4C800Dlx...right move??
C

Tech: it depends. You can probably actually overclock a bit more with the P4P, but you HAVE to to catch the IC7 anyway (clock-to-clock, IC7 wins).

charlie: I know that's what OPP's waiting on...the 3.2.
Raw clockspeed and a severely overclocked vid card gets you to the top of the orb. FSB without the clockspeed to back it up won't get you there.

I don't think 270 FSB 1:1 is doable...you'd be the first I've seen.

Is trading in an IC7 for a P4C a good move?
I don't know. The last BIOS for the IC7 pretty much brought it on par, clock-to-clock. Some people have better luck overclocking with IC7, some with P4C.
A lot of it boils down to sheer luck...you may get a good P4C, or you may get a bad one. All boards (even the same model) are not created equal.

I wish I had the definitive answer for you, but overclocking always has been a crapshoot. Hell, if there WAS a definitive board/chip/memory/cooling solution...EVERYONE would have it ;)

Now what fun would that be? :toast:

zroc, just tell me for certain which is the best...just kidding.

1:1 at 270 would be the first i have seen aswell. Sandra would need a second line to fit the score. I think have finally decided to go with the ic7. I will start messing with a p4p800 today, but from what i have seen the bios is pretty annoying.

gl with your p4c800 dlx, great mobo!

:bananal:

ive seen over ddr540... i definitely think it's doabble with ocz gold and a vdimm modded p4c! gl dude!`

oh, that is right i did see someone with 540 with vdim, but the voltage was so high it would have killed rame quik. I am not sure what you saw, but if you want to do it the ocz gold is the mem to buy.

i saw macci do like ddr580 or something like that with his khx 3000 @ 3.68v :slobber:

what is a khx? and isn't 3.8v realy high, high enough to kill the memory realy fast?

khx = kingston hyperx

and yes, the memory would overheat and cause crashes after about 30 secs lol...

yeah...it doesn't realy count if you can't bench it. Still cool to see that kind of stuff though. Is that long enough for you to grab a screen shot in wcpuid or something?

macci pmed me a screenie a while back of the ram running at 3.68v ddr580 or w/e but i seem to have misplaced it... but to answer your question, yes, it's stable enough to get a screenie!

I'm in the middle of deciding whether I should get a P4P or P4C myself. I've got a 2.4C and it's hit 289mhz 3dmarkable on my 8KNXP but this board just doesn't have enough bios options for me. Although I love the features on it, I want better overclocking. I believe macci had said that the P4P is good for running over 300mhz fsb @ 5:4--and the P4C can't do that. I'm really pushing for a solid 4ghz on my 2.4C.... so I'm thinking P4P. I would need a 334mhz fsb for 4ghz. I know that's getting up there, but it could be possible.

Ideas? Suggestions? Thanks.

Cant get over 315fsb out of mine. Tall wish. Trying myself for the 4ghz mark. I've got a 2.6 coming today, last one wouldnt even clock within 150mhz of my 2.4. Using @ IS7-e

I cant get the IC7 over 295fsb with my good chip, and the P4P does the same 315 fsb on my 2.4 so my chip is maxxed out.

The P4P nor the IC7 will run in my vapo just sticking them in. I have to use 2 power supplies to make those boards run, And hit the power button when it get's to temp.

I was leaning towards the ic7, but i think i am back to leaning towards the p4p800. How easy was it for you to get to 300 fsb? That is my goal under my mcw5000-pt.

Yeah, but I wanna try! :P I may upgrade this processor to a 2.8, but I wanna max this 2.4C out like you have done yourself.

Im about to hook my promedia up to this 2.4, see how it goes. Im hoping to get at least 3.8-3.9 out of it. Maybee ill hit the 4GHz mark.

I can't even make it to 4.0 Ghz with my 3.0 and MachII.
Sure it benches, but fails Prime everytime...

So I guess your expectations are a bit high...

Well the chip is pretty decent... 3D @ 289mhz... 1086mhz oc with 1.6v and aircooling.... I think with a good enough mobo and some LN2 it can hit it.

Just got a 2.6c, Dont have high hopes for it. wont even boot @ 3.2 with 1.7 volts. Oh well going in a customers computer. Gotta keep trying.

I was leaning towards the ic7, but i think i am back to leaning towards the p4p800. How easy was it for you to get to 300 fsb? That is my goal under my mcw5000-pt.

I've got 2 IS7's here, both of them do the same, the IC7 I can get to 300 but not stable. the P4p, Does the same as my IS7, but i cant get any more out of my chip.

I had the same Pelt waterblock you have, Used to use it with my 2.8b, I get the same clock as my vapo, and about the same temps, just less power usage and more piece of mind running 24/7 and away from home

so would you reccomend the ic7? How was the bios of the p4p800, i hear people complaining about it?

You got your MCW5000PT eh ;) ?
Wondering about high FSB board as well as I am tired of fooling around with my P4C800Dlx at the moment. (Good board over all but... I am stuck now at 269FSB... I need something higher).
Oh and one recommendation on it...
Use heatercore (bigger the better and put more than one if you feel like it), decent pump, good volt (13v will cool it good at that high of OC... you get marginal with 12v when oc'd higher than past 3.7ghz with peltier's efficiency), and prepare for warm room :)

has not come in yet... I am using an 86 chevette heatercore with dual shrouded evercool 120's, eheim 1250, and a meanwell 320 at about 13.5v. I hope it is better than my ax7 :exclamati

Good luck with it! Like jinu117 said, prepare for warm room!! My room is hot as hell with those pelts running. I also have a large heatercore from autozone with 2 120s on it and Pro Core with a 120 on it. My temps at 3.8ghz are about 2-3C idle and 27C full load. This is with MCW5000-PT and MCW50-T.

It's a nice setup, I got mine up for sale now though, just ordered my first prommy.:)

Do you know exactly what heatercore you are using? How much did it cost, and what pump are you using?

Not totally related but I could tell you what mine was runninig like. Meanwell set at 13v.
Eheim 1250 dedicated for CPU loop.
1 Chevette HC with shroud/ 1 D-tek Procore with shroud in line with 120mm papast low fan running at 9v outside of case. p4 2.4b @ 1.70-1.75 running @ 3.6ghz or so. (not quite sure on voltage... my memory fades... it turned out to be about 150W on some CPU calculation stuff) would be below freezing point under idle and under full load would hit up to 19c. Keep in mind air flow is highly optimized with radiators outside of case.
The other loop was running Eheim 1048 with MCW-50PT BIX rev2, etc, etc. Couldn't tell what temp but ran very cool :)

Id get the IS7 if i were using a 2.4 or 2.6, And above that get the IC7. No problems with the P4P, i just dont like asus much, I sold that board in a customers computer. But it was a good board.

Nice setup. Thanks for the info. I think i might pickup a 1048 and another heatercore and put my gpu on another loop. It wouldn't cost but like $50, and i bet it would help a good bit.

Thanks for the suggestion. It realy seems like you just can't miss with any of these 3 boards. I think i am going to stay away from the is7 because my friends is just horrible. I think it is defective...wait i know it is...but he doesn't care so he won't rma it. It seems that without the memory preformance enhancers on the is7 is a good bit below the ic7 and p4p800, and i see all kinds of hd corruption when it is enabled at high oc's. It also seems to be pretty unstable with mem enhancers on at high oc's, and they don't yield much gain at high fsb. I think I am just going to get the ic7. Gotta wait for a good deal though :D, anyone want to give their's up eheheh?

I cant seem to get this out of my IC7


I still love my IS7 though, who needs the memory enhancers, Only seems to make it unstable on either board,

Nice score. Ok...so i guess i will give in...the is7 is back in the picture. Wow that made it so easy, now instead of being deadlocked with 2 mobos, it is 3...:help:!?

what mem and proc is that? what fsb are you at, or is that a 1:1 divider.

edit--> nm i see that stuff in your sig. I think that the ocz did was the problem with my friends is7. well not ocz, but just that specific set of sticks he got. I am almost positive it is bad mem. I think i still want to get the ocz gold though, I think all of the mem problems have been cleared up, so it should be fine.

The IC7 is faster CLOCK for CLOCK. I just cant seem to get my IC7 up as high as my IS7. But what i do get it up to makes up for the 2% difference. Im using a IS7-e 5:4.

I thought about the OCZ gold, just need to see some more people with it. And hoping for Price to drop. I usually unload my "pretested stuff" ie.... used ;) hehe in customers computers.

Hard to unload $200+ worth 2x256 memory though!!! unless i just :smileysex to them
