My house.
Processor AMD Athlon 64 X2 4800+ Brisbane @ 2.8GHz (224x12.5, 1.425V)
Motherboard Gigabyte sumthin-or-another, it's got an nForce 430
Cooling Dual 120mm case fans front/rear, Arctic Cooling Freezer 64 Pro, Zalman VF-900 on GPU
Memory 2GB G.Skill DDR2 800
Video Card(s) Sapphire X850XT @ 580/600
Storage WD 160 GB SATA hard drive.
Display(s) Hanns G 19" widescreen, 5ms response time, 1440x900
Case Thermaltake Soprano (black with side window).
Audio Device(s) Soundblaster Live! 24 bit (paired with X-530 speakers).
Power Supply ThermalTake 430W TR2
Software XP Home SP2, can't wait for Vista SP1.
Regardless of theoretical performance, the upcoming AMD RD790 and Athlon 64 Black Edition line of processors certainly are overclockable and feature-laden. On nothing but air cooling, MSI testers were able to get an RD790 chipset to a remarkable 510MHz FSB speed. Once the RD790 is released with PCI Express 2, CrossFire X, and support for goodies such as Phenom, we will see one seriously good platform.

Thats great, but what was the clock speed on the chip? 510 is ok, but if your CPU can't go that high, it's worthless(Unless you lower the multiplier and then the only benifit is the RAM speed).
 
i think it was just a test to see how how the fsb can go.

So they effectivly lowered the speed of the chip to get a higher FSB. Smart. :wtf:

Sometimes it can be, I've heard -- not by as much as they did in this test, of course. Getting 510mhz here was merely a Proof of Concept.
 
correct mdm, this is simply to show there is no significant FSB wall at least up to 510FSB which is awesome and means that the new phenoms should have a ton of potential on RD790!
 
Looks like they are showing the limits of both the Phenom and the RD790 by dropping the multiplier.

The Phenom shown in that screenshot has a ~25% overclock.

Unfortunately, the screenshot above (from the link) looks seriously photo-shopped.

What do you look for when deciding if it is shopped or not?
Just curious.
 
CPU-Z screen added, I'm sorry I forgot about it earlier :banghead:.
 
shouldnt it be bus speed and HT link on that cpuz screeny, not FSB and bus? It is AMD after all....

however, it may just be a bug, who knows. I would like to think it could handle that high an bus speed as it will be sweet for hi end RAM modules

like this:

Amazing potential. When I first looked at it, I was like the poster above who said, 510mhz and a multi of 5 and not much for speed. But when I thought about it, the Phenom has amazing potential to clock to 4ghz or more. Sweet score for AMD
 
Shouldnt the lettering be blue, and the text in the box?

I get the lettering as black when use the Windows Classic theme.
 
if its photoshopped, why does the validation number work?

You get it reported as Bus Speed when you look at the pic provided on validation links. With CPU-Z 1.41, my Santa Ana 1216 Opteron is shown as a Santa Rosa so things like this are to be expected.

so, who's getting AMD for their next PC :)
 
count me in, though I have to say my upgrades are going to get farther and farther apart. married and bout to have kids.

and if they could get that result on phase with an 8x mult, I'd buy both easily.

It's not a Phenom. It's a 6400+, and it's actually 22% underclocked.

ahhh good to know then! :toast:
 
that is pretty sick but class :D well done
 
Right... so AMD prove they can do 500fsb and some you think thats a great reason to buy AMD cpus again... I fail to see the logic...

Having a high fsb might allow more memory bandwidth but if it isn't actually filled and used by the cpu then isn't it overkill, like giving a mini a Ferrari engine?

For example: Pentium 4 (prescott + D models) look at all the good quad pumping the fsb did for intel when they finally realised that 5ghz wasn't really a viable consumer option. :/

And AMD aren't using DDR3 so this is a bit premature :P

Me, as I have for the past six years. And the one after that, and the one AFTER that, and the...well you get the idea. Unless AMD goes completely out of business, and even then there would be a steady supply of AMD parts for years on eBay and such. I'm done with Intel. I kicked that bit*h out, threw her sh*t on the street and blocked her phone number. As for VIA? I don't play with toys anymore.
