I am beginning to wonder if I just have a board mobo or something. I bought this machine back in december of 2005. I have never had a problem with the system except for 2 things. Neither have been a big issue. My games are rock solid, so is windows and all programs. Excellent frame rates and everyday usage. The 2 things I can not seem to fix atm are
1. Cant seem to get this setup to over 215mhz to get any good OC's
2. USB ports will not power certain external HDD's. IE: any thumb stick is fine, any powered external HDD is fine. My Lacie 40gig which will work in any laptop and my other 2 PC's will not come up in my main computer unless I use the attached extra power usb plug.
Mobo, Abit A8N has gotten the latest bios, had it for awhile, latest bios is freakin 1 jan 2006. I cant see it being the proc or ram unless I have some unknown ESD damage.
I was playing around with the Guru OC and I was able to get the system to do a lousy 215mhz. I tried 220mhz and it hard booted on me. I put the voltage up to 1.4V and set the bus to 212mhz to get the 2.5ghz but I dont feel comfortable to go any higher since 220 crashed the box.
Stock speeds I get very good temps and all, and I can encode a full dvd to avi autogk rip done in under 35-40 minutes. I just see all these nice numbers from alot of other people and I just wonder if something is wrong with the mobo to get any higher. I have one of the first 4800's being I bought it at its insertion around end of the year 2005 so its one of the 110w version.
 
So I take it no one else has this kind of combo? Anyone else at least have the same kind of ram and mobo?
OCZ platinum ram and abit an8 board?
 
check the ram settings, try loosening the timings or increase the rams voltage (I would go check what the rated voltage for your ram is and set it at that, most mobos if not all defaul to 1.8v, my ram since its high end is rated at 2.20.

But dont over do memory voltage or you will fudge it up, thats why I say go find the spec sheet for your ram.
 
First.... stop playing with uGURU. Overclocking should be done from the BIOS.

Second... it seems to me like you need a refresher (or lesson) in how to overclock an A64 based system.

Check out the two links..

Link to the Definitive A64 overclocking guide. Very informative. (Don't worry, the same rules apply to all A64 systems, not just DFI based motherboards)

Link to Eclipse's OC guide.

Either one will help you determine WHAT exactly is holding you back.... you must test your CPU independantly from the RAM. Once you know the MAXIMUM limits of the CPU and RAM, you can find a common middle ground to set your overclock at.

You have very good RAM and a decent "enthusiast's" motherboard.... I find it difficult to believe that you can't go 20MHz over the default FSB without a system boot. Somthing sounds fishy. Time for some reading/researching

Good Luck
 
I appreciate the info guys. I will check into my ram settings and re-look at those 2 links. Only reason I tried the guru thing was because it looked similar the other program I was using on my 3700+, at work forgot the name of the program.
 
The thing about the USB not being able to power an external hard drive:

That is not necessarily a problem with the motherboard. If you use a flash drive (thumb drive) sure the USB will power that up fine. But a real hard drive that has a spinning disk in it requires more juice and can't necessarily take its power from USB without external power. That's why most of the aftermarket USB hubs include an AC adaptor.
 
I understand that, I work with usb devices all the time. The only thing I was trying to point out is that the lacie drive, which does come with an external power usb wire and it does work with that plugged in. This is the only computer/laptop that I have ever plugged the device into that isnt able to power it. (except for those old laptops that dont have 2.0) Just seems a bit lame that a Nforce4 Ultra board can not power a usb device that every other computer I have used it on does. Thats one of the reasons why I thought there might be something wrong with the board in some way.
 
Wow, I was missing some information. I was still thinking of the old P3 and P4 days. I had forgotten that the AMD64's used their own HTT and didnt know you had to keep that ratio going between the 2 major numbers. Got some homework to do. This A64MemFreq11.zip is a nice tool to use though.
