Asus A7N8x Settings (Memory)

[jjessico]

I am building a Athlon XP 2100+ system with corsair 333mhz DDR and am trying to setup up the memory speed on an asus a7n8x. What should the speed be set at? The options arre 100, 133, and 166. Also any tips on tweaking a system of this sort would be appreciated.
Thanks,
Jason

I would put the CPU at 166 FSB (And begin overclocking) and put the ram @ 100%. Then lower the timings; on my crucial I get 6-3-3-2.5 @ 166 (I can push it higher but then I get coldboot problems). Since you are some Corsair I'd say try 5-2-2-2 and see if it works

I have pc3200 ram, but found better benchmarks by using ram timed synchronously with the cpu fsb than at 400 (200MHz).

So if I'm understanding this correctly.. I should get better performance out of my XP2100 with PC2700 then I would with PC3200 since it's sync'd with the FSB of the chip?

I guess what I'm wondering is what is the stock setting and multiplier as this 2100+ has a stock HSF and really just needs to be stable and nothing special.

I need some help too. I have the A7N8X deluxe with XP 2100 (and another with 2200) both using single sticks of 512mb Crucial PC2700. Could someone explain (to a dummy) 6-3-3-2.5.....I know its a setting in the bios but the manual really doesn't do much as far as explaining what each option in the bios really does. It will say something like "this disables or enables ...blah,blah,blah....it's all Japenese to me!

What do you mean when you say "put the ram @100%"

I know I need to make some changes in the bios like the graphics card being AGP and not PCI but could someone tell me what else should be changed from the default settings.

I did read the two huge threads in the forums already.

You must have read the wrong ones then

In the advanced chipset features section of the BIOS, there is an option to set the sync rate of your bios relitive to your FSB. The default is By SPD ( I believe ) which they are reccomending that you reset to a percentage. If you change your settings to User Define, you can change the sync rate in percentages. I believe there are range choices from 50-200%, in 13.3% increments. Set it to 100 if you're going to try the overclock route. Only do this, of course, if your ram can handle it

Myself, I am at 10x185 atm, with ram synced. ( Xp2200+ chip. I dont push it far in steps for stability. ) Stupid BIOS reads this as 1840MHz for some stupid reason, but sandra say its at 1850. shrug.

I have 3 computers at home that I used this mobo for. They all have some issues I need to deal with.....I never had this many issues with my previous Asus mobos....a7v133 and a7v266 went fine right off the bat....

MY device manager has some errors:
1394 bus controller
PCI raid controller
creative sb16 emulation

Whan I put the Nforce2 cd in the drive I get "Ascdsio.dll SMBus_WriteByte Failed!" What does that mean....

I can almost gaurantee that Memtest will fail if you do not run CPU and RAM in sync. Unless you have a 333MHz-FSB CPU, I wouldn't run the RAM at 166MHz. Again, Memtest should easily prove this theory.

I recently built three nForce2-based systems (one used the Asus A7N8X Deluxe). All of them failed Memtest on the last 1MB of RAM when I ran async (CPU @133, RAM@166). After switching to sync (133/133), no errors at all.
