That's called the Vdimm mod and if you go to any search engine and search for 'IS7 vdimm mod' and similar (memory mod, memory modification, vmod, etc.), you should find some pages. 3.1v is a good target to shoot for. I have a P4C800-E Deluxe which is almost as bad at 2.85v MAX, and I did the Vdimm mod on it to get 3.1v and that got me about 25mhz more bus (DDR562 now). I use Geil Ultra Platinum PC4000. (The BIOS is set to 2.85v, which is really 3.1v now).
Hi,
I'm having my video card listed as a PCI card when it's AGP and I think it's the root of my problems.
I'll list my system first:
PC 3200 Cosair 512mb ddr
IS7 Motherboard
Geforce FX 5900XT AGP
P4-2.8E
Enermax 480W
Maxtor 80G
SB live
Problem is happening after I install the intel inf drivers. I installed them since the NVIDIA drivers detected the video card in the pci slot. After installing the drivers, nvidia detected them correctly(AGP 8X), but the vc starts putting all these weird colors after bootup(bleeding colors sometimes)..then returns to normal(but i can't start 3d apps). Also, putting the agp apature at 4x makes windows lock up and reboot(8x works but has those colors). I reformated again, following the instructions from the stickylinks but I keep getting the same problem. Try doing safe reboot
in the 4x agp mode, it freezes on the agpxxxx.sys file(x= i have no idea what the full name is)
I don't think it's the video card because before I formatted the video card,it worked fine(when i didn't have the inf drivers installed/when nvidia dectected it as a pci card). Games ran fine..but a little slow(since it was pci). I'm thinking it's the board..but I'm opened to any help/suggestions before I return the board. Also, is it normal for windows to list the location ofthe video card in PCI Bus 1?

You should always first install the mobo's drivers, then install the AGP video card's drivers. What you are describing usually happens when the video drivers are installed before the mobo's drivers. The mobo's drivers have things like the AGP miniport driver, and other bus mastering drivers which is usually needed for the video card to be seen properly.
It usually doesn't matter, but make sure in the BIOS the AGP slot is set to the initial display and not the PCI slot.
I tried something new: I dunno if it's the board or the cpu itself, but the video card works(no colors and game works fine) when I lower the external clock to 166(35 mhz for pci and 69-70mhz for agp)(or 2.35 ghz for the cpu).
This is after reformatting and reinstalling and taking care to install the MB drivers before the VC drivers.

Both clocks are locked.
Lowering the external clock helps below 2.4 ghz..i dunno WHY
I even tried disabling hyper threading but that had no effect.

But are they locked at 66/33mhz? Raising those on this mobo can cause problems. Even with them set to "auto" they are not locked at 66/33mhz.
If you're using XP Pro, no need to reformat, just use the system restore before doing anything.
If you've tried the latest mobo drivers and latest video card drivers, then I don't know what else to suggest, sorry. I only had this mobo for about a week when I built a PC for a customer. I'm sure some current users will have some info for you when they get here.

Hello. I'm new to the forums and I have a question for you guys. I made a mistake in buying RAM for my first gaming Rig, an AMD Athlon XP 2500+ with Asus A7N8X. I bought A pair of matched sticks from Mushkin PC3200, 1GB but they were Blue Line, with practically 0 OC'ing habilities and very high Latency numbers.
I don't want to make that mistake again in this Intel rig, an Abit IS7, P4 2.8 HT. I want the best ram for this machine, with Great OCing and low latency. I have a budget of $300 for 1GB (minimun) of RAM and there's a catch, I'm from Latin America and I can only buy form Fry's Online store, Outpost.com. I have narrowed it down the list to the following but feel free to recommend other memory manufacturers or sticks.
Geil 1GB PC4000 500MHz 2x64x64 (2x512MB) Ultra Platinum Dual Channel DDR
CAS 2.5 7-4-4 @ DDR500MHz PC4000 $269.99
Corsair 1GB PC4000 500MHz 2-64x64 XMS Pro TwinX Dual-Channel DDR
CAS 3-4-4-8 @ DDR500MHz PC4000 $299.99
OCZ 512MB PC4000 500MHz 2-32x64 (2x256MB) Dual Channel DDR Gold Edition (2 of this for 1GB)
CL 2.5-4-4-8 @ DDR500MHz PC4000 $179.99
Thanks in advanced for your help.

Hi,
Firstly these comments are from my experience - I now have plenty on IS-7 MOBO's and I can tell you this:
Corsair is tested to run at their quoted speeds at 2.75v, this is important because you can only pump 2.75v through the DIMMS (the unit undervolts at 2.8v). I got my IS7-E up to 262FSB on a 2.8e using PC4400 RAM - It's pricey but you know that it's been tested to run at the max volts you can get to it.
Previous to corsair I tried Geil - This ram really needs 2.9 volts to unleash it's power, the timings are better than Corsair, but coz I could not get the 2.9v it underperformed and held back my overclock.
2ndly - If you are going to overclock the IS7 board does not like to run Dual Channel enabled at FSB higher than 220Mhz, anything over that and you have to use slots 1&2 or 3&4.
In regard to DIMMS, try and use dimms with chips on one side of the board only, apparently GAT settingd work better and you'll get a bit more performance from them (I think ADATA offer this in 512MB configs).
The RAM you choose will determine the GAT setting that you can use, it's safe to say though that if you decide to overclock you will be disablling and manually adjusting every setting.
Finally you can't use all four DIMMS if you intend to overclock - the IS7 series does not provide enough volts to the DIMMS (you can perform a volt mod to get around this though).
This information has been compiled over several weeks of attempting massive overclocks with Geil and Corsair memory - it will provide you with a solid base to a happier experience than the one I had.
May The Force Be With You..........

Just to clarify your other question - Having been an AMD user for a while.
All AMD systems love low latency RAM, plus you can relax the timings, pump up the volts and get better overclock (of course you need 2.9 or 3.0v going through them to get them to perform).
You must now unlearn what you have learned.
P4 Mobo's that will run at 260FSB+ have ultra high bandwidth, to get your memory to run at these speeds you have high latency timings as standard.
P4 Mobos using 865 or 875 chipsets do not like RAM running at CL2, CL2.5 or CL3 is what you need if you intend to get the most form the system.
You must forget about latencies and go for all out speed, get some PC4400, forget about the other timings they are irrelevant - This RAM will run as high as 275Mhz FSB which means that your CPU will become unstable before your ram, unless you have Vaporchill or similar.
One more thing to consider is that to get the best out of your system you have to run the RAM in Sync with your CPU which is why you need such high bus speed (remember bus speed = bandwidth, latency is irrelavent).
Mind what you have learned today, save you it can...........

Thanks for the massive info. I didn't expected to be answered so soon, but I'm glad I decided to post. You have lit my path. I'll go for the Corsair 1GB PC4000 500MHz 2-64x64 XMS Pro TwinX Dual-Channel DDR because I don't have the extra $150 for the 4400 and also it's the only Corsair PC4000 outpost.com carries.
I've a couple of doubts still about temperatures. When started using the MOBO I noticed very very high temperatures (under load nearly 66 C.). I got a little nervous until I read that Abit has this problem, always reading high. I updated the BIOS to the latest (20) and my temperatures dropped to (53 C. under load). I live in Latin America ( in a very hot city, nearly 31 to 36 C.) and I have a Zalman 7000ALcu but I have the case open. What do you think about this? Do you think I have capacity to OC?
Thanks a lot.

Hi,
Anything is possible!!
Suggest you change your cooler for something more powerful - in the UK we recommend the use of the Thermalright SP94 with the use of a 92mm fan. Also use Artic Silver 5 Thermal compound - once this has settled temps should drop 2-3 degs Celsius.
You are right about the high temp reading on Abit IS7's, even so you are running warm now so an overclock of somewhere between 230 & 250FSB should be achievable.
The max load temp of a P4 (as stated by Intel) is 68deg Celsius so be mindful of this and overclock in small steps to make sure you do not exceed this temp.
Good luck and enjoy.

I'm currently using Artic Silver 3, will I see a big difference with the Artic Silver 5? I bought the Zalman for the reliability and it's low noise. My AMD screams, and I wanted a this Intel to be virtually noiseless... I will have in mind the Thermalright, I currently have the previous model SP90, I think, in my AMD with a Vantec Tornado of 80mm.
I'm aware of my high temps. I know that a great part of it is because of my case, it's too small. I don't have a place here in my country where I can buy this kind of stuff and ordering from the US will be expensive, for an item like that.
I think if I can get to an stable 240FSB I'll be happy. But first I'll have to wait for the memory...
I'll buy it next week and hopefully have it here by July.
Take care, maverik007.

Anybody else ever experience this problem? (Standard IS7 motherboard)
As of recently both my mouse and keyboard have been acting up ( I tried them on different computers they are fine), the problem is, for example, my keyboard will automatically go into cap locks mode and the light on the keyboard that indicates the caps lock isn't even on. And the keyboard will sometimes just stop typing on me. My temporary solution as of late was just to click somwhere on the desktop for about 4-5 times and then go back into the window (aim or word document).
The mouse would also act up the same time my keyboard does, this problem here is instead of the cursor going in between words, for example, it will begin highlighting and then as i begin to click anywhere (webpage) it will just highlight. And i have a mouse where u can scroll up and down, and instead of it scrolling it will act as a back and foward button.
The problem doesn't take long to fix, but you know stuff like this can be annoying. Sometimes it can really be a pain and I end up unplugging the keyboard and plugging it back in, same with the mouse and then it begins to go fine.
I am curious is if the usb ports are dying perhaps? I just don't see what else it can be besides the motherboard acting up.
Thanks for any feed back.

Single 80GB SATA WDC Caviar (model WD800JD) ON ICH5R SATA1

I started this pc from a brand new build. Fresh parts. No overclocking. Anyway, I first started getting blue screens in WinXP, during OS install. Blue screens were indicating to check the hard drive for corruption, and to remove any recently installed drives?.etc...
Then I reinstalled XP and installed both (ICH5R & INTEL) SATA drivers via (F6) during XP install. I was then able to successfully complete the XP installation.
Upon first booting to the desktop successfully, after XP install (with the XP CD still in cdrom), I then reboot XP to make sure it boots properly and remove XP CD in cdrom.
Upon reboot, after verifying DMI Pool, I get the classic error message:
?DMI POOL DATA
Disk Boot Failure, insert system disk and press enter?
but if I rebooted with the XP CD, the CD would of course prompt me to ?hit any key to boot of CD? and I don?t, it then proceeds and boots from the Hard Drive to XP. Weird???
I have tried all kinds of variations in the BIOS settings and of course checking the boot sequence to make sure it tries to boot to HD and I'm using the latest BIOS in support of p4 2.8e Prescott.
It will only boot to XP off Hard Drive, if XP CD is in the CDROM drive. What?s going on???
I?ve been building PC?s for the last 8 years.
SOMEONE PLEASE HELP, I?m going crazy!! Why can't I boot to XP on SATA?? I think the problem lies somewhere within the SATA controller or controllers...???
Please Help!

I will have in my possession tomorrow an IS7 and a 3.0C. I will post detailed OC results and benchmarks here.
Hi there, I can't get a boot up, or monitor up on my ABIT IS7-E/P4 2.6Ghz C/ Swiftech MCX-4000 setup
When i push the power button, i get a long beep followed by a pause and then again a long beep...I have tried everything, clearing the Cmos couple of times....re-adjusting the heatsink/fan..Changing RAM dimms, a different PSU.
I have all the fans working, including the North bridge fan, I also have both Green and Red LEDs active on the mobo.
I'm using Crucial 256DDR PC3200 and a Thermaltake 420W PSU.
any idea whats wrong here?
Thanks.

I don't recall if this mobo uses AMI or Award, I think Award. At any rate check BIOS beep codes here: http://bioscentral.com/beepcodes/awardbeep.htm and I don't see anything for Award and one long beep. At the right side of the page is more brands' beep codes.
Wierd IS7 problem
Hi,
I have an IS7-E2 which works just fine with my old P4 2.4b processor, buut if I put in a 3.0ghz c I get all manner of errors and problems. Upping the voltage to 1.7 helps but it's still not really stable. I've tested my RAM and it seems ok (hours of memtestx86), performed fresh installs of XP (with the 2.4b, system doesn't last long enough with the 3.0 c....). I'd assume I had a duff cpu, but I've tried another 3.0c and the results are the same...
Pulling my hair out here? Have I got a duff board? And if so, how can it run so stabily with the 2.4b? Any advice gratefully received!

Try updating your BIOS version. The last Bios (Release 20) even has support for the Presscotts... Maybe you should try it.
Most, if not all of these 865/875 mobo's support PC2700 and above, probably PC2100 as well. Of course this depends on the CPU. If you're running an 800mhz FSB P4, then you need a minimum of PC3200. If the mobo can support the older 400mhz bus P4's, then it can support PC2100 with that CPU type. The slower the default speed of the CPU, the FASTER the memory you need. The faster the default speed of the CPU, the slower the memory you need. (This is because of the higher multiplier of faster CPU's). This is why a 2.4C @3ghz is faster than a 3ghz CPU @3ghz due to the fact the memory bus is faster. All of this is if you want the most from a setup and plan to O'clock. If one never plans to O'clock, PC3200 is fine. A 2.4C used with PC4000 and the PC4000 running at its default speed of DDR500/250mhz bus will be a 3ghz speed for the CPU.
