Have a read of this:
Might be handy....
Okay after a bit of trial and error I managed to create a bootable USB memory key, that boots into DOS so that I could flash the BIOS.
I downloaded WinImage 7.0, which lets you write disk images to floppies, memory sticks and CDs.
Then I downloaded the Win98SE boot disk image from bootdisk.com (near the bottom, in the section titled "Non-Windows Based Image Files W/ImageApp").
I extracted the WIN98SEC.IMG file from the zip and then opened it with WinImage. I set WinImage to use the USB memory key and then hit Write disk. (Note: I did this on a WinXP 32-bit laptop. I haven't tested whether WinImage works on x64 but the website shows x64 versions are available).
I stuck the memory stick in the x64 machine, rebooted it, hit Escape at the POST screen to bring up the boot menu and chose to boot from the memory stick. This booted me into a Windows 98 MS-DOS prompt, where I could happily run the RUNME.BAT supplied with the ABit BIOS upgrade.
Notes: I found a couple of guides about creating bootable USb memory sticks (from aaltonen.us and PC Answers). I tried some of the other tools mentioned in these guides first - like the HP USB Disk storage tool and MBRTool but I had limited success with them. Could be worth trying if my method doesn't work for you though.

crowy,
That's a good thing to know. Don't know if it will work on all computers but.... I knew that you could boot from a memory stick but I didn't know that you could flash the BIOS that way. Just out of curiosity, what's the drive letter become? I don't think you could use it to install RAID drivers because the default and only drive XP lets you use is drive A. If it becomes drive A, then it might work. Thanks crowy!
Happy Computering,

I'm not sure,but if there is no floppy drive(which is why you would use this method)maybe the memory stick becomes removable device "A".

In the storage or any other technology industry, the golden rule of marketing is that larger numbers sell. Regardless of what the numbers mean, large numbers are the only thing easily understood by the vast majority consumers and storage is no exception. Conventional wisdom in the server and home enthusiast market says that more expensive high-RPM hard drives translate to better performance, but is this really true? I?m going to debunk this myth once and for all and prove to you that not only are you paying more money but you?re getting less storage and less performance.
Storage performance for the vast majority of applications other than the rare case of the video distribution database or uncompressed HD video storage relies almost solely on low access times which translates directly to higher IOPS (Input Output Per Second). Database applications such as ERP and CRM rely heavily on IOPS performance while the role of transfer rate performance is nearly insignificant. This is precisely why high-end database systems will use solid state flash-based storage even though flash memory tends four times slower than hard drives in terms of raw transfer rate. The hard drive would be like the dragster trying to compete against a "slower" formula one racing car which is like flash memory in a street race with lots of tight turns. The name of the game for most applications when looking for the ideal hard drive is the device with the highest IOPS and the lowest access times.
Let?s look at a typical 147 GB high-end 15000 RPM hard drive with a super low average seek time of 3.7 milliseconds. Average seek time is defined as the average time it takes the read/write head to move from one random track to another track on the hard drive. We also need to account for rotational latency and the 15000 rotations per minute translates to 250 rotations per second which is 4 milliseconds per rotation. This means that the average rotational latency is 2 milliseconds because it can be anywhere from 0 to 4 milliseconds. Since the overall access time is determined by the sum of the average rotational latency and the average seek time, this high-end 15000 RPM hard drive has an average access time of 5.7 milliseconds.
This means it takes an average of just over 1/175th of a second for the hard drive to jump from one random location to another which means it can do a theoretical average of 175 IOPS for zero-size files. If the operations were for files averaging 32 KB and we know that 150 of these files adds up to 4.8 megabytes of data that needs to be transferred which would consume less than 1/10th of a second since the hard drive is capable of copying more than 10 times that data in one second. This means it would mean that the hard drive would spend a little less than 10% of the time doing actual data transfer instead of seeking for data which would lower our IOPS results by approximately 10% for 32 KB data blocks which means we should expect to see 158 IOPS. How accurate is this calculation? If we look up Storage Review?s database for hard drive performance and we jump to "IOMeter File Server - 1 I/O", we see that the Seagate Cheetah 15K.4 hard drive gets 159 IOPS in real world testing which means the prediction was accurate.
Now let?s take a look at a 300 GB 10000 RPM hard drive that costs slightly more than the 147 GB 15000 RPM hard drive. This 10K RPM drive has an average rotational latency of 3 milliseconds which is 50% higher than the 15K RPM drive. It has an average seek time of 4.3 ms which is half a millisecond slower than the 15K RPM drive. Therefore the 10K RPM drive has an average access time of 7.3 milliseconds which means it can do a maximum of 137 IOPS for zero-size files. For 36 KB files, it would take up roughly 10% of the IOPS performance which means we should expect to see around 124 IOPS. Looking at the Storage Review performance database again, we see the actual benchmarked value is 124 IOPS.
So we have an obvious performance winner right since 159 IOPS is better than 124 IOPS? Not so fast! Remember that the 15K RPM drive is less than 1/2 the size of the 10K RPM drive. This means we could partial stroke the hard drive (this is official storage terminology) and get much better performance levels at the same storage capacity. The top 150 GB portion of the 10K drive could be used for performance while the second 150 GB portion of the 10K drive could be used for off-peak archival and data mirroring. Because we?re partial stroking the drive using data partitions, we can effectively cut the average seek time in half to 2.15 ms. This means the average access time of the hard drive is cut to 5.15 ms which is actually better than the 15K RPM hard drive! The partial stroked 10K RPM drive would produce a maximum of 194 IOPS which is much better than 175 IOPS of the 15K RPM drive. So not only do we get an extra 150 GB archival drive for slightly more money, the active 150 GB portion of the drive is actually a better performer than the entire 147 GB 15K RPM drive.
But this is a comparison on server drive components and we can actually see a more dramatic effect when we?re talking about the desktop storage market. In that market, you will actually pay DOUBLE for 1/4th the capacity on 73 GB 10K SATA RPM drives than typical 300 GB 7200 RPM SATA hard drives. Now the speed difference is more significant since the 7200 RPM drives have typical average seek times in the 8.9 millisecond range and you have to add 4.17 milliseconds average rotational latency for a relatively pathetic access time of 13.07 milliseconds. The 10K RPM SATA drive designed for the enthusiast performance desktop market has an average access time of 7.7 milliseconds. But since the 300 GB 7200 RPM drive is 4 times bigger than the 73 GB 10K drive, we can actually use quarter stroking and end up with a high-performance 75 GB partition along with a 225 GB partition we can use for large file archival such as a DVD collection.
By quarter stroking the 300 GB drive, we can actually shave 6.68 ms off the seek time which means we?ll actually end up with an average access time of 6.4 milliseconds which is significantly faster than the 10K RPM "performance" drive. This means that PC enthusiasts are paying twice the money for a slower hard drive with a quarter of the storage capacity!

so if you partition your drive so each platter is a drive you get a boost, will you lose the performance boost if its using more than one drive/partition at a time?

It's not technically a boost overall, it's just making it seem like you have lots of smaller drives, granted it is a performance "boost" though. You won't lose all the gain if you're looking at more than one partition at a time as badly as if you were combing the whole drive as the data location is within a smaller area, but probably most of it.

At last the system is back up as it should be and now the fun has properly started.
Now running a stable 3.6GHz on E6600 in the P5WDH
Even on air the Mobo is running @ 36`C and the CPU @ 39`C
Will start to push it a bit higher over the next few days, but at present quite happy with this 50% gain on stock speed, plus there are other benchmarks I want to start running as well.
Finally broke 15 Secs on Super-Pi as well with 14.219 Secs.

I was impressed, if it wasn't for the noise, I'd leave the air cooler on.
I'm trying to post the screen shots, but keep having trouble with imageshack, as soon as I've sorted it I'll update post with the shots.

Its certainly a monster.
I am putting together a shopping list to fit the watercooling on it, and also looking at making a few alterations to the layout in the case.

I haven't seen anything higher, although I hadn't looked.
I'm currently on my laptop as the main PC is running some more tests at 3.68, I'll need to up the CPU voltage I think to get any higher, at 1.5 for now.
I'm not too sure how far I'll get without the VMCH mod to take the NB voltage up beyond 1.65 Volts.
Currently now got 13.797 1M Super-Pi.

Will do.
I seriously love this Mobo/CPU.
Just got it to 3.74 and Superpi now 13.516 1M, 33.859 for 2M.
PCMark 05 was at 9543, so will try and run at 3.74GHz and see if I can get over the 10K.
Temps now 42'C on CPU and 36'C on Mobo (my little blue fan on NB is working a treat).

Hi guys im in a need of a little help/advice
My current system is:
AMD A64 3700+ Sandi Arctic Cooling Alpine
Asus A8N Sli SE
1 gig Kingston HyperX BH5
Gigabyte 6800GT with NV Sliencer 5 Rev3
2x 200 GIG Maxtor DM10's Sata (Not in raid)
Some DVDRW drives
basically i would like to overclock this more than i allready have but im a little baffled with this technical talk
basically i have the cpu at 2.47gig
http://valid.x86-secret.com/show_oc.php?id=125258 <<if that helps
i have seen on forums of this cpu much higher on air with the standard amd fan any help would be appreciated
the overclocking i have done was with manual settings in bios Vcore is at 1.46

crowys the man you need for this
but with my limited know how
does the bios have any options with ldt multi or cpu to nb that could be keeping that down,but it wont be holding you back.
can you go any higher with the vcore voltage?
edit
try turning ai nos and qfan off aswell as cool and quite fan
2nd
what is the hyper transport frequency multi set at?

As seen here, I have so far managed to get the system up to 3.8GHZ on air (not bad for a 2.4GHz CPU).
Can run Super-pi up to 32M without any issues, but the system crashes if I try and run a full PCMark05 test suite.
Super-Pi to 1M is now @ 13.110 Secs, now more than halved the best I ever got with the FX60 setup.
Time to leave the CPU alone for a while (now back at 3.0GHz) and start cranking up the memory to see what that is capable of.
Its apprently tested to 1115MHz and expected to get to a speed of 1200, so time to see exactly what it can do.
I'm also ordering the resister to do the Vmch mod as well, as I think thats where I'm bombing out when trying to get to 4.0GHz.

Yeah, outstanding though that superpi is, if it ain't stable, it's no overclock imo. I'm very impressed with what you've achieved so far though.

You'll find there are very varied opinions in the overclocking world as to what counts, the lists include system post, operating system loading and then tests, at least the system does post and boot so its well on its way.
True, the same goes for me with the stability; if I can't pass all the tests then it doesn't count as a properly overclocked system.
If you don?t accept the test results then there?s no point running them.
As for super-pi, then the best scores out there are now currently 10.??? Secs, and those scores although validated as the top scores, don't have any other proof that the systems are in any other way stable, so I'm sure there are plenty of people out there with less than 100% perfect systems, that top the rankings on benchmarking.
Best I've managed at stable for all tests now is 3.68, I don't think it's going any higher until the Vmod is done in the near future, I'll do it at the same time as putting the water-cooling in.
Although I'm having trouble getting all the bits from one place, and the postage costs are a joke at some of the sites, so doing the homework on the system is taking longer than anticipated.
