At this point, the 8IHXP, is still not fully supported by EasyTune. When it is, then, we'll have more OC options. For the time being, I uninstalled ET completely, use only the available Bios F4 OC options.

Running fsb 150 (1850), Kingston 1066-32 rdram 256 X 2, slots 1 & 2 only, air cool, very solid, passes 3DM fine, runs apps & games flawlessly. Filling all slots leads to less memory bandwidth performance. This is an excellent board, & being a former Abit Th7II user, I wouldn't be happy with an unstable OC board. Gigabyte is on the right path. When EasyTune support is fully implemented, along with better 1066 memory choices, the 8IHXP will be more recognized for the great board it is.

Some points:
1. Unless you use rdram 1066, getting a 850E board is pointless, as there are several 850 boards that can OC very well with rdram 800-45 or 800-40.
2. The new 32bit RIMM 850E boards (Asus for now) may not have RIMM 4200 memory available for some time, no one really knows. Some are saying 32bit RIMM 4200 will be scarce for months, even after it finally hits the market.
3. No speed advantage to 32bit rdram over 16bit rdram. The 16bit 850E boards have 4 slots, more flexibility, than the 32bit 850E boards. I've yet to read of a 32bit 850E board with more than 2 slots. The issue of buying the mem in pairs (16bit boards) or not (32bit boards), is essentially a non-issue. There'a a lot more 16bit rdram to choose from & OCers need 128 or 256 modules for best overV-rimm results.
4. The Gigabyte Utility manager helps you keep an eye on temps, etc., small footprint, can d/l new bios etc.. No need for EasyTune right now.
5. The 8IHXP will run 2.8Ghz cpu. Hopefully, by then, high yield batches of Samsung 1066 rdram will be on the market, providing more OC stability, than currently seen with the 1066 Kingston (Toshiba) rdram. Since rdram 800-45 can be used on some mobos OC to over 3Ghz, air cool, I think 1066 still has headroom to play around with, regarding the issue of practical OC limitations. My suggestion is to consider quality PSUs, if building new sys, to avoid problems with P4 systems, especially if you're OCing. Very satisfied with Enermax 650W, but would be overkill for some. (I have 4 hdds plus other stuff on sys.)
6. Successfully OCed this board to fsb 156, air cool, Bios features only. Above fsb 152 becomes more difficult for some games & apps, but I suspect that's memory related.

cobravst & bingo13, could u guys tell me the what are the tweakings needed in bios to o/c the board?? or did u used the Eztune4 software provided by gigabyte to do the o/c?

Really nothing to it! Just go into the bios, set FSB to whatever you want to try, and reboot. If it doesn't reboot at that speed, try raising the VCORE up a little and keep trying till she boots. If it boots into Windows, then stress test it and see if it keeps running smoothly without any hiccups. If you are using PC1066, you cannot select 3x mode for the RDRAM in bios. There is a SPD on the chips that tell the motherboard to automatically run in 4x mode (this can be proven by changing to 3x in the bios, running SiSoft Sandra, and doing a Motherboard Info test, or a Memory benchmark). Personally, spend the couple of extra dollars and get the PC1066! Why else would you buy a 850e board for but to run at at least 133FSB...

I haven't installed EZTune 4 as I do not have my parallel port enabled. EZTune requires the parallel port to be enabled to work.

There has been much talk lately about the performance of 16bit vs. 32bit RDRAM. There isn't any! They are virtually both the same, except 1 needs to be used in pairs (hence single sided) vs. a single chip (again, double sided). Performance wise they are identical!

I have no problems recommending the 8IHXP to anyone who's looking to buy a motherboard now that utilizes RDRAM! This board is a solid performer! I do not recommend this board to anyone that is running a 1.6A processor though, as the max FSB is 156. Most 1.6A's will do 160FSB without sweating. Here is where the Asus P4T533 may come in handy as it allows FSB ranges all the way up to 200! However, since Intel seems to be dropping prices rather quickly on the higher end P4's, pairing this board up with a 2.0 (100 FSB) or a 2.26 (133) is a sweet OC and giving the performance of RDRAM, would make for a nice fast system!

Someone also was asking about the purpose of the dual bios chips, and rather it raised performace. No, it does not raise performance. All it does is give some insurance against a flakey flash upgrade or a dead bios chip. Instead of either having to send the motherboard back to the manufacturer or ordering a new bios chip, you just turn the computer back on and it automatically reverts to the other bios.

My system consists of GA-8IHXP, P4 1.8A, 2 x 128mb 1066 kingston RDRAM, asus geforce 3 Ti 200. i raised the fsb to 118 in bios but found my 3DMark score to be lower after o/c.

This is because you cannot set the AGP/PCI frequencies. They are set automatically depending on which FSB you select. Try for the gusto and go right to 133FSB. That should cure your slower 3DMark scores :)

Anyone running with a USB keyboard and/or mouse?

The 81hxp can do this, and it will free up some IRQs, right?

I will be buying this board, do i need ECC or nonECC rdram? Should i buy the single stick rdram or the stuff you have to buy in pairs?

CoolRadiation,

Ditto on what CobraSVT wrote. :)
The best settings I have used is changing the memory to 4x for PC1066. Auto caused some issues at 156 for me.
I tried EasyTune4 but it only works for raising the fsb speed and will not work correctly doing that with a 400fsb chip. It will also reduce your memory timings and caused a 3% hit in my setup not to mention it seemed to be a bit buggy after several hours of usage.
I turned off all serial/parallel/modem/sound options as I do not use them. I also disabled the NEC USB chipset.
I slowly increased my vcore settings while testing to ensure I had absolute stability. On my 2.4b and 2.26 I settled on 1.575 at the 154/156 fsb setting. Your mileage will vary but it seems as though June and later pack dates are requiring less voltage in my testing.
Depending upon your Kingston memory you might need the overvoltage option after 145fsb. My latest lots do not require it up to 156fsb now.
Ensure all three power connectors are used. This board loves the juice. ;)
You need to start at 133fsb or else you will have trouble. I tossed a 1.6a in last week and I had to start at 133 in order to go higher.
Are you using the Promise controller?
Are you using the Realtek lan?
Are you using any other PCI cards?
I will PM you a complete list of bios settings once I get home.

later...

MarthaStewart,
Buy non-ecc memory. This board requires memory in pairs. At this time your best choice is the Kingston PC1066.

Vidcutter,
I am using a USB Keyboard/Mouse. The best way to free up IRQs is to disable the serial/parallel ports if you do not use them. I also did not enable the NEC USB ports. The USB ports also use multiple IRQs but they tend to share nicely.

Bellyofthebeast,

We will not have any futher options in overclocking once EasyTune4 fully supports this board.
I have not had any issues getting R-4200 memory since last week. I am having better overclocking results with it than I did with the first batches of PC1066. I would highly suggest the Asus P4T-533 as another i850e board to purchase. My test results have been great to date with this board.

hi, i have managed to o/c to 133 but then its not that stable. I cant seem to set the RDRAM freq in the bios to 4x(1066) though. my options are only PC800, PC600 and auto. Is that normal?? I am sure that my ram are 1066 though.... went to kingston website to check the serial code on the ram cases. Maybe that has to do with my cpu being a 1.8A (400fsb)

FYI
I have only one PCI TV tuner card installed. I am using the on board LAN and sound but not the RAID controller.

Anyway, the F4 version of the bios for this board is out (Download at Gigabyte ). Solves the problem for the installation of the usb 2.0 drivers:)

Leave the RDRAM speed set to AUTO when running at 133FSB. This will allow your RDRAM to run at PC1066. As far as not being stable, try upping the VCORE more. Mine runs at 1.65v, so I actually have my VCORE set to 1.675 in the bios. It reads 1.64-65 in Gigabytes HW monitor and SiSoft Sandra 2002 Pro. With PC1066, there is an onboard SPD (just like on DDR) that won't allow you to select 3x mode for RDRAM. It always runs at 4x (this has been confirmed not only on the 8IHXP, but with users trying to run PC1066 @ 3x on the TH7-II). My 1.8A is dud past 135FSB. No matter how much voltage I give it, its not stable. However, with my setup, my board never gets above 44C even after playing NASCAR 2002 online for several hours! Like I said above, this board is a rock solid performer! Just wish people would stop thinking that RIMM4200 is faster than PC1066, and that the 8IHXP doesn't support ECC. Whoever started that rumor is a moron!

Good luck and keep us posted on your progress...

My GA-8IHXP performs awesome. I havent had any problems besides with the ich4 usb 2.0. I installed the drivers off the cd and device manager says the device isnt working properly and the ports dont work, any way to fix this? The NEC USB chip is working fine. BTW, you can enable ECC in the Bios, pretty easy to do too, i forgot how to though and i dont feel like looking cause im lazy. :)

update your bios to the F4 version posted on Gigabyte's website. That will take care of the USB issues.
