Abit IS7 Thread

[Tedinde]

Loading XP on the IS7-e now. Asus p4p didnt come in yet. Just flashed the bios to the 1.3 beta. . I'll give the details in a little while.

But please dont expect anything as good as ZROCS Pulitzer prize reviews!!!

Temp seems a little hot on a stock heatsink?? Gonna go to an alpha after testing stock. Then in my Vapo PE.

The geil memory i have here has made it to 470 ddr with 2.8 volts in a older epox 4bGA mb, with a 3:4 Multiplier so im guessing that's what i have to work with. Got some good corsair here makes it to 460 ddr, and just got some buffalo 5ns chips also.

Let me go clear some space on my Hosting site.

Ok here's some stock numbers on memory


Stock 200 fsbCas 222 settings geil platinum 3500 no volts 2.4ghz




Same cas 222 settings Changed memory to ultra 200 fsb 2.4ghz




That's almost a 15% boost. Probably wont hold up as it scales higher, As creatives above didnt @ 275mhz, but lets see.

[Tedinde]

Creative and the others. Just checking my DDR volts. Doesnt matter where i set it. It still shows 2.62 volts?? weather i set it @ 2.5 or 2.8?? Does yours change when you actually change it??

This geil does need volts. let me know.

Corrupted my testing HD, gotta reload XP, Knew i shoulda made a Ghost image!!!!

[Tedinde]

Back again.

Somethings strange, I cant boot into windows whenever i select the new "TURBO or ULTRA" above 220 fsb, no matter what divider.

Blamed it on corrupted HD, it wasnt. Getting the blue screen, XP config sys bad.

Turned off ultra and ok, Turned my memory settings to creatives above 275fsb.....2-5-3-2..... and getting the same numbers without the ultra or turbo mode

275fsb no ultra or turbo 4:5 memory


Compare to Creative's when he put's pics here

[Tedinde]

Got a max of 287 fsb or 3444mhz on the factory heatsink @ 1.62 volts, Getting hot though 65C. Fired up 2 instances of F@H, stable and holding @ 74. hot in this room though!!! Gotta head to the store. See if it's still folding when i get back, Then try out an alpha on it. Then Vapo.

In winbonds HW monitor, PWM temps are 70 now. Im assuming it's the Northbridge temps, it's listed below CPU temps. I aim a 60mm delta screamer @ the Northbridge and the temps drop. Course could be the Mosfet temps?? Hmm guess i should read the manual!!! hehe dropped 20 degrees C' must be the mosfets.

[Creative]

Heya Ted

Sorry time differences mean I just woke up :p
hehehehehe

With the vdimm issue, yep I set it to 2.80 in bios and can only ever see a maximum of 2.74 in Winbond Hardware. Same as MBM5 also. Hipro has mentioned where you can measure it from, the coils next to the socket, but I havnt found a spot where it shows a reading yet


With the new bios and Turbo etc, my pc wont even start either if I put her either one of Turbo or Ultra.....but all this is doing is changing the Refesh Cycle Time 2 options above the Turbo option in Advanced menu. I can put mine manually to stregthened and all is good. Aggresive and mobo just beeps at me.....its the same with Chainbolt, his machine just beeps at him when he selects Turbo or Ultra, but its fine if he sets manually.....again he can only use from Strengthened down also


Here is a memory comparison for you at 275fsb 2-5-3-2 and the old bios and then 275fsb 2-5-3-2 Stengthened with the new bios....looks similar to yours actually

OLD BIOS


NEW BIOS


So as you can see, a fairly nice boost in performance....that actually is present after ocing also. SOme say the p4p800 loses it edge when overclocked....not the abit though

287fsb is simply awesome Ted. I can get it to prime at 280 for a few mins but then she stops....275fsb is 100% prime ok though....just testing out some new NB cooling today so see how that goes.

I was seeing mid 70s temps on the cpu also when using the default cooler so I backed down about 100mhz and .05 vcore and the temps dropped 10 degrees so I was happy....this was folding too

Have u checked the mosfets around the cpu socket? They get pretty hot but its hard to fit ramchips in there due to the tight space. PWM temp, im not sure about. It sits at about 50ish for me and then I start up my 30cm 100+cfm fan and she dies down to about 24-31degrees....so Im the same as you and wouldnt have a clue what it is measuring ???

Its annoying cos I get stability and then i try something and then its unstable.....eg I was folding at 280fsb for about 4 days and now I cant fold above 277fsb I am thinking its either my ram or the NB cooling isnt adequate.....atm Ive got a TT Tiger heatsink on there with a 50mm 20cfm fan connected to it blowing over the NB.....Havnt got a temp probe on me atm....really should go up and by a new battery
hehehehe


Anyways, hope this is some good info for you bud. Im glad theres another user now in the forum who has one and will be using a Vapo etc. Dont expect any troubles with the IS7 and Vapo, just plug her in and away you go!!!!

Cheers

ps
as per sig, Ive had to change ram timings to get some sort of stability.....which leads me to believe its my ram.....

pps
grrr testing prime while folding at same time now at 280fsb again....2-5-3-2 freeze after 2 tests.......2-5-3-3 freeze after 4 tests......now im going to try 2-6-3-3.......Im convinced its my ram.....must get my mate with his awesome corsair stick over here today to test it out....

Unfortunately I'm having a lot of instability with my IS7-E. I'm not sure why? Can't find any BIOS updates, and I'm not sure what Creative's BIOS ver, is for? Is It just to upgrade Gigabit LAN?

Can anyone tell me how I should optimize the BIOS settings? I'm using OCZ Dual Channel 3700 GOlD (2x256MB) and have enabled PSB800 N/B Strap, Fixed PCI/AGP etc., andn tried both 5:4, and 3:2 memory at 2800MHz and above. The hihjest Vcore I've tried is 1.625V.

Here is the bio file that I am using. It adds some extra options into the Advanced Chipeset menu.

THe gigabit lan, it has now been revealed that the earlier IS7 boards were released with the Gigabit lan and not the normal 10/100 one. I forget the reason, something about not having enough boards so they just sent out pcbs with the gigabit lan on them...but they are not afaik releasing anymore with it on.....you had to get an early one...which I did

In the bios file I have linked, ABit have included a .doc file showing you the performance and bios tweaks that you should do to get the best performance. Have a read and then play with it and see how u go.

Personally, I think this bios may be a little unstable compared to the first ones etc.....Im finding I cant reach the levels of fsb I was reaching in the first week or so of having the board.....and all ive really changed is bios.....Ive changed ram in diff slots but thats shouldnt matter should it?

Hmmmmmm

[Tedinde]

Your scores are right on with mine i see. The mosfets were screaming hot getting up to 75C, just putting a fan on them brought them down to 44c now. I've got some ramsinks already cut for a 8RDA+ i was putting together for someeon. About to put them on and stick it in my vapo.

My geil memory needs volts like i said. How the hyperX your using doing?? My corsair wont do better than my geil it's older 3200.

Im going to need some better memory to really get down.


As far as the turbo and ultra, they work @ stock 200fsb, over that it's like the HD wont boot. But then im getting nice numbers.

Havnt tried any 3dmark, Just stuck a 8mb PCI in it for testing on my back desk.

This is a killer $97 board, im using the cheap IS7-e, The p4p I ordered should be here tomorrow to try out and a 2.6 chip.

I ordered the abit when noticing in the vapo forums everyone was having major problems with all the new ASUS boards in a vapo. ASUS is usually Vapochills recommended board of choice.

Guess i'll be up later than I should. Time to get some Mem volt mod action going. About to plug in the soldering iron.

F@H always hates high FSB, but i have 2 instances cranking away. This should hopefully get me over that 1000 points per day mark!!!! hehe.

[Tedinde]

An if anyone cares, the IS7-e I have also has the gigabit lan 3 com

and here's a link to the bios file im using.

IS7,IS7-g and IS7-e beta bios

[Creative]

Nice Ted

My HyperX isnt cutting it I dont think. I have just put it to 3:2 and will try priming with that....if she keeps freezing them i know for sure its mem, if not then its cpu.....Ive had this HyperX sticks running at 240mhz (180fsb) in an IT7 at 2-5-2-2 but had to use 3.10vdimm.....bit more beefier than 2.74
hehehehe

For the fets, your ramsinks must be very small cos I tried to fit some but nah the capacitors are all in the way

errrrr I just put it to 3:2 divider and as soon as I get into windows the pc freezes.....err isnt 3:2 less aggresive that 5:4??!!!

I really should be studying though, exams nextweek
hehehehehe

[Edit: Rebooted after it froze and now im up to test 36 of the 1024K tests in prime.....using above settings.....2-6-3-3 @ 3:2 divider @ 278fsb ]

[kevdogg]

man i want this board... but i need some ram that can get me to 300fsb with low voltage!

[kevdogg]

w/ a 5:4 divider of course

[Tedinde]

Just tried my old 1.6a in it. Max on air i could get in a epox 4ga4+ was 2740 mhz, Purring along fine @ 2864mhz 179fsb. Might as well order another IS7 for this chip.

This board is reporting about 10C higher temps than the other board, on the same chip

3:4 and 4:5 400 and 533fsb multipliers work fine with the older chips Getting about 4500 in sisoft memory with the 1.6a, Where was this board 6 months ago.

Stupid Granite bay boards!!!! I waited so long for!!!!! And charging over $200 for them. Man im still ranting about that BS@!!!!!

[TysonM]

Hi Tedinde!

Have you seen this interesting article about 3:2 as opposed to 5:4? http://www.overclockers.com/articles756/

When you stick that in the vapo check out how it runs at 3:2 (200 memory gets you 3600mhz). I'm trying to figure which board to get and also have a Vapochill I plan to use.. would be interested in whatever you find out!

[Tedinde]

Yeah i read it. The memory is my worry. I have a 2.6 coming also and a asus P4p board, The asus wont play nice in my vapo, unless you run 2 PS and do a little dance with the power button. I know im going to have to go to the 3:2 in the vapo with a 2.4 and probably the 2.6.

Im building a nice OC'd rig for a customer, But keeping the best for me!!! Im using Geil 3500 platinum, that i've had to 480 ddr in a epox board with a 3:4 mult. Im gonna have to get some Volts to the memory though.

Here's the max i can get out of the factory heatsink. And that's it for the night it's 1am here.


291fsb A little cooler in my computer room since the sun went down hours ago. about 15 degrees cooler air.

[Creative]

OK after about 2 hours of testing since posting, I have decided its my cpu that is playing up.

I was at 278fsb and tested all possible ram timings and all possible dividers and nothing was stable.....Take it back to 275fsb and presto, I can run 2xfolding clients and prime and still running as I type this

It had nothing to do with the NB cooling, nothing to do with my ram either.....it was just my cpu......but hows this.....I could prime at 278fsb for 52 mins 2-5-3-2 but anything looser than that would fail after ~10 mins Then after that i could never get 278 stable again......even more

I wrote this to a mate on icq earlier while testing

when u open 2 folding clients it puts the cpu at 100% cos x2, but when 1 folding client open it only runs at 50%....this is the same as Prime.....

hmmmmmmmm so im thinking that we have a fake sense of stability with the HT chips cos when u are stressing using one program, you are only running at 50% cpu!!!!!!

or whas this been known for ages?
lol

He has suggested I tried seti cos that uses 100% cpu

Ill be back

[Edit: As I clicked send......2 folding still running....put some prime into the mix.....prime got to test 12 and then i got an illegal error box for prime and clicked ok and prime shut down.

folding still running....its definantly cpu related.....]

[taco]

this board is looking yummy, all except that its only got 2.8v on the vmem. is there a vmem mod for this board yet? or is it similiar to the IC7 vmem mod..

ahhh which to get, IC7 or IS7...

[Tedinde]

Yeah there is a vmem same as the IC7, look in the xtreme voltage forum in here


Also here is a new 1.4 beta bios for the IS7's

gonna try it out. Supposed to give even more!!!! Got it from abit forums

http://mywebpages.comcast.net/tedind...s/is7g13b4.zip

[taco]

how much more voltage is it suppose to give? anyone flashed it? seems like theres a new bios for this board coming out everyday.

[Creative]

IS7 cannot give more volts in its current form

You have to add a resistor like the IC7 and IT7....



ps
just grabbed the bios and will be flashing soon. Ive been runing cpu intense programs since posting and have found 275fsb to be 100% stable now running seti and priming together for 1 hour....thats stable for me. So yer imo its cpu related.....

I LOVE THIS BOARD DID I MENTION THAT YET???!!!

[Creative]

Can u pls post piccys of your vdimm mod pls pc ice

I know it might be the same as the IS7, but I just wanna see yours

Cheers

ps
is there some way I can use grabbers or do I HAVE to resolder a new resistor onto the board? I dunno, the P4P vdimm mod sounds easier so im maybe tempted to change over to it....

[Tedinde]

You have to take off the resister that's on there, it's a zero ohm. Gotta head out now to get a 1k 0hm pot. Easy enough desolder/solder. Same as the IC7.

Just flashed to the new bios i linked above also. I'll let you know how it is.

[Creative]

Heading to bed now, 1am here now

Gotta be up for my 9800 delivery in the morning.....

Will look forward to your results with the bios Ted....I didnt even up flashing....ive been testing more with my rig...

[Tedinde]

Ok the new bios I posted above. get's rid of the Turbo/ ultra setting option, but adds like the new IC7 Turbo/street racer / F1. Nothing else new.


Here's stock numbers, seems same as before, 200fsb cpu 2.4ghz, I dont see anything extra as far as speed.


here's sisoft at stock, didnt feel like screenies this time

Auto setting/off....... 4542/4521
Turbo....................... 4906/4927
Street Racer..............4929/4967
F1...............................5088/5102

Same numbers i was getting before stock, And running @ 275fsb 5:4 im getting 6075/6088 on street Racer setting Ultra wont boot. off to radio shack for now!!!

Only other thing is the computer seems to boot faster?? Enough to notice.

[Creative]

woah quick post
hehehe

So this bios is better or worse? I dont like the 1.3beta3 to be honest.....
