1 out of 5 eggsBios issues

Pros: Worked for a few minutes before issues arose.

Cons: Bios is freezing up; Sometimes it takes 90 seconds to go from a black screen (more often than not, it does nothing) to seeing anything and then freezes during post.

Pros: this was a very nice motherboard but my first asrock motherboard and it was nice to see it had a built in buillten board to be able to change the drive on the fly to boot from great suprize thanks newegg

Cons: well the memory was the hardest thing i had 15 sticks of memory rangeing from 256 to 2 gb and it would only run 2 of those sticks period but they were the same speed all them said they were the same but no not this motherboard but it is a nice motherboard

2 out of 5 eggsWon't POST using E7200 Core Duo

Pros: System works great when it's booted up. Using E7200 Core Duo, it can stream video smoothly at 720p using AGP GeForce 6200 (breaks up at 1080p) using Windows XP and FreeBSD 10 with Firefox. No problems with any drivers included in the CD for Windows XP and 98. Very nice being able to play my Win 98 games again.

Cons: The BIOS seriously needs a patch to support E7200 Core Duo. Motherboard is running with 1066 MHz FSB, 2 DDR400 500 MB RAM (1 GB), and AGP GeForce 6200. I turn my computer off every time I am done using it. Every time I turn it back on, it will not POST. I hit my reset button, alt/cntl/del, does not matter. Every time I first turn on the computer, I must power it off, shut off the power supply, and reset CMOS. To make it livable, I installed a slide switch in the front of my case and attached it to the CMOS pins so I can easily reset the CMOS. If I swap the CPU with a Pentium 4, no problems POSTing.

I returned my first board because of the POSTing problem and got the same result with the second board. Went to ASRock's website hoping there was a BIOS update but there is only 1 version which is the same as what comes with the board. I still tried flashing the BIOS with the website version but still works the same. Even when I strip everything off the motherboard and only use 1 RAM stick (I tried multiple RAMs) and 1 hard drive (again tried multiple HDs), I still have to reset the CMOS with the pain of retyping the date and time back in along with going through multiple screens and re-modifying the Boot Sequence.

If it wasn't for wanting just 1 computer with the combination of running my Windows 98 software and wanting the extra speed to stream HD Video at 720p, I would have returned the board and got my money back.

Other Thoughts: If you are using a Pentium 4, you are probably OK. My Pentium 4 processor worked fine. If you have a Core Duo processor that is over 800 MHz FSB, I believe you are taking a risk of having the same problem. If you leave your computer on 24/7, then you probably would not care much.

Manufacturer Response:

4 out of 5 eggs

Pros: Allows you to add multi-core CPUs to older single-core systems without having to replace everything else.

Cons: More RAM slots and SATA connectors would be nice.

Other Thoughts: I got this MB, along with a refurbished E7500 Core2 Duo and a secondhand Asus Xonar HDAV1.3 Slim soundcard to hold me over until I was ready to build a new i5 or i7 based PC. That was more then six month ago and I feel no pressing need to get started on a new build. I'm not a gamer so I don't need to upgrade my PC often. I just wanted to be able to play my uncompressed blu-ray rips at full resolution with DTS-MA/Dolby TrueHD bitstreaming. This PC now does so flawlessly whereas with my old 478 3.0GHz P4 it struggled with 720P streams, nevermind blu-ray.

Because the RAM runs at 1.77 MHz with 1066 FSB processors ReadyBoost actually makes a noticeable difference. Programs launch much faster and web pages load virtually instantly. Since I'm running Vista32 I used 4GB of a 8GB USB flash drive. If this MB would support more than 2GB of RAM I would have installed Windows 7 64-bit instead.

I also had to add a PCI SATA card since I need 4 SATA connectors (3 hard drives and an eSATA port).

Even though this is an ancient system it serves my current needs and is fast enough. I'll probably keep using it as my main PC until Vista support ends in 2017.

The rest of my system:

630 watt Rosewill PS
E7500 Core2 Duo
2 x 1 GB Super Talent DDR400
HIS Radeon HD 4670 AGP
Asus Xonar HDAV1.3 Slim soundcard
500GB Seagate SATA boot drive
2 x 2TB Seagate SATA III storage drives
2 x 80GB Seatgate ATA100 drives (just because I have them)
Pioneer DVR-107D ATA DVD-R/W

1 out of 5 eggsASRock 775I65G R3.0 LGA775

Pros: Bought from Newegg.

Cons: MB Video Chip failed after two months, Drivers would not load. Tried my NVidia 7600 AGP Card, still Monitor would said "no signal". Board is Junk, going to RMA from Newegg. In this case paying for the extended warranty will come in handy. First bad MB from ASRock I've bought after eight years.

Other Thoughts: Had to reinstall my old Prescott 800 MB to get my Win 7 Home Premium 32 Bit working again. My Six year old P-4, 3 GHz still works great and booted up my Windfows 7 like it was nothing.

Manufacturer Response:

4 out of 5 eggsGreat AGP board

Pros: Best AGP board around. Chance to use left over IDE and AGP parts.

Cons: Memory is a bit slow.

Other Thoughts: I had s couple of 3850 AGP boards in socket A boards. This was a chance to couple these with X6800 cpu I had. This would be a perfect AGP board it the memory access speed was a bit better and the capacity was increased some. Current setup has 2 IDE optical drives with 1 IDE hard drive. There is I serial drive attached to the IDE channel with and adapter and 1 serial drive as the boot device on serial channel 1. Drive bandwidth is a bit slow but it is old tech after all.

4 out of 5 eggsOutstanding Opportunity!

Pros: When I saw this motherboard offered at Newegg I got VERY excited! I had in mind to build a new computer capable of playing “old” games and this fit the bill to a tee! The pros:

1) The Intel 865 chipset is supported by Windows 9X, Windows XP, and higher

2) The AGP 8x slot allows using the highest level video cards supported by Windows 98 and Windows ME.

3) The driver disk contains hardware support for Windows 9X and Windows XP

4) Has the ability to raise FSB and RAM voltage to facilitate mild overclocking. Some higher-end DDR memory requires the ability to raise voltage higher than the specified 2.5 volt. This motherboard can go to 2.7 volts.

5) Has the ability to unlock the CPU multiplier to reduce it (if you wanted to raise FSB but keep the overall CPU speed the same). In order to do this, Intel Speedstep Technology has to be disabled.

6) 2 SATA connections. They are slow SATA I type, but still you can use narrow cables to promote good airflow. Be sure to set the hard drives into “Compatibility Mode” when booting into an OS that does not support SATA.

7) The kicker – It used to be that the Pentium D was the highest level socket 775 processor that the 865 chipset would support. This motherboard has support for Core 2 Conroe and Kentsfield processors, as well as lower-end Wolfdale processors. These are significantly faster than the Pentium Ds.

Cons: There are no real cons if you accept that you are dealing with older tech that is being pushed to the limit. That said, I would offer these caveats. In no particular order:

1) The motherboard specs give a 300Mhz FSB limit, but that doesn’t guarantee you can get that high. I ran into an FSB wall at 263Mhz; it booted successfully and loaded Windows. At 264 and 265, the computer froze during POST. At 266 it would not POST. Yes, I lowered the processor multiplier to the minimum and used the 2/3 RAM divider in order to isolate the effect of FSB tinkering. This was a little disappointing because this board supposedly has support for 266FSB processors automatically.

2) It appears I was able to get a stable torture test (Prime 95 for 1 hour) at 250 FSB, but I had the processor running significantly slower than spec. Previous attempts to test that 250 Mhz FSB and running the processor close to spec resulted in crashes about 15 minutes into the test. It is possible that I need a better cooler than the stock Intel.

3) Let’s face it, overclocking from 200Mhz to 250Mhz FSB no longer makes for an impressive gain, compared to the performance of more modern tech.

4) No ability to adjust Vcore. This will limit the ability to get a stable processor overclock.

5) I would not count on being able to purchase the lower-end processor in a family (like the E5200, 2.5 Ghz and 12.5 multi) and expect that I could overclock to match the performance of the higher-end processor in the family (like the E5800, 3.2 Ghz and 16 multi), as you may run into issues with the higher FSB or the processor voltage.

6) Only 2 RAM slots with the ability to have 2 GB max. This may limit what you can do when using a higher operating system than Windows XP or 64 bit operating system. On the other hand, some tweaking of the “system.ini” file is needed to be able to get Windows 98/ME to run with that much RAM installed.

Other Thoughts: Bottom line is that I have a system that screams when running games produced between 1995 and 2005. The idea for this project came as a result of my not being able to run old X-wing and Tie Fighter space combat simulation games in Windows XP or Windows 7. These games were improved ports of the DOS versions and specified Windows 95/98 as the required operating systems. Attempts to get them to run on higher Windows failed, even when using the correct compatibility settings. These and other games have no problem running in Windows ME. Currently the system dual-boots into Windows ME and Windows XP, and should have enough hardware juice to run a higher level Windows OS when Microsoft no longer supports Windows XP. With DOSBOX installed on the XP side, this PC should be able to run 20 years’ worth of games!

The computer specs:

1) ASRock 775I65G R3.0 Motherboard
2) Intel Pentium Dual Core E5800 (3.2Ghz, 2MB L2 Cache)
3) 2GB G.Skill DDR 400 CL2.5 (sold at Newegg and requires higher voltage to run)
4) Nvidia Geforce 6800 Ultra (the highest level video card officially supported with Windows 98/ME drivers)
5) LG DVD-RW SATA Optical Drive
6) 80 GB Western Digital SATA HD
7) Generic Floppy Drive (still needed for installing Windows 98/ME)
8) Inland Gold 500W Power Supply
9) Antec VSK 4000E Case
10) Dual booting into Windows ME and Windows XP. (Expect to install a 2nd hard drive for backup/higher Windows OS eventually.)

I tried to answer just about all the questions I had when I was looking into this motherboard. I was not able to experiment with the 266 FSB Core 2 processors, so I can’t give first-hand knowledge about that. Other folks are saying that when the motherboard automatically detects it, everything is locked and overclocking is even more limited. I hope I helped somebody with their purchase decision.

5 out of 5 eggsThe greatest little AGP board

Pros: - Core 2 Quad support
- Official support for Wolfdale (45nm) CPUs(R2.0 supported them with bios 3.30 but not officially)
- Works with Windows 7 out of the box. The built in Windows drivers work fine.
- Apparently they fixed the slow boot of R2.0. A big plus.

Cons: - Core 2 micro-architecture support requires CL2.5 RAM. Not really a con, just a heads up.
- Only 2 RAM slots.
- VRMs can't handle an overclocked Quad. If you plan to overclock stick with dual cores.
- Max FSB is 300Mhz. Again, not a con just a heads up.
- CPUs with 1066FSB will force RAM to run at 3:2 (177Mhz) no matter what setting you select on bios. This is done to maintain CL at 2.5.

Other Thoughts: I have owned the R2.0 version of this board almost since it was released and this is one of the boards that shows Asrock's trademark ingenuity: imagine a board drafted for Pentium 4s that by its EOL gets Core 2 Quad support. Or a modern board released in 2013 that ships with a floppy connector. That's Asrock for you, always thinking of the quirky customer.

The first system I build with this was a Pentium D805 overclocked beyond 4Ghz (FSB was 205 or so) plus an AiW X800XT AGP from a previous build. Those were the good days. We thought AGP would hold on for another 10 years or so (lol, yeah right). I later replaced it with the Conroe865PE when I upgraded to a Core 2 Quad (the VRMs on the 775i65G couldn't handle the overclock) but I still have it in use paired with a Pentium E5800 (wolfdale) and a HIS HD4350 AGP in a low profile case. It sees some action when my brother comes over to play RTS vs me.

This re-release certainly is something else: who would think of releasing an AGP board on the year 2013? No joke, I'm tempted to pick one as a backup for my R2.0. It looks godly in black. I would LOVE a re-issue of its big brother, the Conroe865PE. Still have mine.

Review is for the R2.0 but the layout and components seem to be the same so I think pros and cons still apply.

4 out of 5 eggsGreat for Window98se

Pros: Very fast with Core Duo E5800. Window 98SE installs and works fast-comes with Win98se drivers. Probably the latest drivers-the Intel win98se drivers are dated around 2003-4.

Cons: Native USB 2.0 wasn't reading Sandisk right in DOS. I had to reflash the BIOS which seemed to correct it. The capacitors are cheap, not sure how long this board will last without recapping. I couldn't boot Windows 98se from a SATA drive(not even in compatability mode) like I can with a VIA chipset.

5 out of 5 eggsLast Great AGP MB

Pros: Last great AGP Motherboard currently available anywhere. Have this MB running with a Intel Core 2 Quad Q6600 2.40GHz processor, probably the last AGP graphics card made by HIS Radeon HD 4670, powered by a BFG 650 watt power supply and a 120GB SSD Drive with a 2GB Western Digital hard drive for data,pics and music. There's an SB Audigy Sound card with 2GB of Memory. Have this wrapped up in a Kooler Master Centurion Mid-Tower case with a see-through side panel.

Cons: No windows 7 Drivers. Old Technology, but vintage for me. Had a previous version of this MB that used a E6600 Dual Core 2 processor but wouldn't work with R3.0. Expensive for old technology.

Other Thoughts: Last of the Mohicans...AGP still alive and kicking and this Motherboard is it. Thanks to ASRock for still making the last know AGP Motherboard available anywhere and thanks to Newegg for carrying it.
