A7N8X 233mhz FSB

[foxkm]

It can be done. I have a screenshot of wcpuid HERE

Here are my specs:

A7N8X Standard - Betabios 001.c
Unlocked Athlon 1800+ (Palamino) running at 1624mhz
FSB: 233mhz (466mhz ddr)
Clock Multiplier: 7
Memory : 2 x Low Quality PC3200 - only will run up to 160mhz stabilly so I set the memory speed to 155mhz (60% fsb)

I will post some benchmarks later.

Curious to see if you get any better bench marks with that high of a FSB, since your memory would still be a bottleneck. You should run some benchs with a 1:1 ratio, and then again with the FSB overclocked that high for a comparison. Would be interesting anyways.

i'm betting its lower than running it sync 200/200, maybe even lower than sync 166/166

The importance is he got a great motherboard.

Sweet deal

I have done some benchmarking with different speed settings, here is the study details:

Setup:

Motherboard - Asus A7N8X Bios 1002 Beta 1
CPU - Unlocked Athlon XP 1800+ (Palamino)
Memory - 2 x No Name PC3200 w/ Ramsinks (Dual Chanel Mode)
Video - Gainward Golden Sample GF4 4200 (default clock speeds)

OS - Windows XP Service Pack 1
Sisoft Sandra 2003
3d Mark 2001 SE
PC Mark 2002



Setting 1:
FSB: 233mhz (466DDR)
CPU Clock: 1636
Memory Speed 155mhz 2.5CL 6/3/3
Sandra:
CPU Benchmark: 6078int / 2439float

Memory Bandwidth 2698int / 2450float
3D mark: 7888 3d Mark
PC Mark: 5105cpu / 4757mem

Setting 2:
FSB: 133mhz (266DDR)
CPU Clock: 1533
Memory Speed 133mhz 2.5CL 6/3/3
Sandra:

PC Mark: 4643cpu / 3772mem

Setting 3:
FSB: 166mhz (333DDR)
CPU Clock: 1583
Memory Speed 166mhz 3CL 6/3/3
Sandra:
CPU Benchmark: 5882int / 2349float
Multimedia: 9733int / 9814float
Memory Bandwidth 2378int / 2205float
3D mark: 7906 3d Mark
PC Mark: 4484cpu / 4364mem

Setting 4:
FSB: 2000mhz (400DDR)
CPU Clock: 1600
Memory Speed 150mhz 2.5CL 6/3/3
Sandra:
CPU Benchmark: 6005int / 2421float

Memory Bandwidth 2387int / 2182float
3D mark: 7670 3d Mark
PC Mark: 4931cpu / 4317mem

Well, it looks as if these numbers show that the AMD athlon XP cpu performs multimedia / games much faster with the memory synched, regardless of the BUS speed
The greater difference between the bus speed and the memory, the more performance is sacraficed to align the data to the two buses.

I now just need to get some Corsair PC3500 Sticks and a Tbred B 2100, then we be rocking!!!

Hope this is insightful to many

Do I need to get a different version of the Bios in order to unlock 200x2 FSB? or physically mod the chip? when I look in the bios it offers FSB of 100, 133 and 166 and it seems that all the multipliers are there. I saw in the manual that there was a jumper to enable 200 Mhz FSB only, but it referred to the others as 200, 266 and 333 so I assumed they meant 200 (100x2), not the 400 (200x2) I'm looking for. Toss me a clue

Nice. Some benchies plz. Also head over to Overclockers.com and tell Ed your results.

Play with the settings in the Advanced Chipset area (where you set the FSB clock).

You must set one of the darn things to "User Defined" to get more than 100/133/166. Also, the 1001g doesn't support overclocking I think. It will let you do it, but when you POST it will stop and say "Overclock" detected, and thwart your attempts.

My 8RDA+ did 233MHz * 7 too on a 1800+ Tbred. It can be done, but the memory is always the culprit.
