ASUS mainboards OFFICIALLY CRAP!

Asus boards are CRAP! but no websites dare say it.
For example on tomshadware they said this:

From CUSL2 review in 815 roundup:
"Asus has far the best overclocking motherboard right now"

HERE: http://www6.tomshardware.com/mainboard/00q3/000906/i815...

No mention of any probs at all, in fact it got praised.


NOW, in the recent celeron review the board used was the ASUS TUSL2 which features the exact same overclocking features in the bios as the previous CUSL2.

HERE: http://www4.tomshardware.com/cpu/01q4/011003/duel-11.ht...

and this was pointed out;

From Celeron 1200 vs Duron 1100 article:
"The Celeron 1200 was overclocked to 1500 MHz without any problem at all in the test. When this happens, the FSB runs at a speed of 125 MHz, the PCI bus at 41.5 MHz and the AGP bus at 83 MHz. Sensitive components such as the GeForce 3 graphics cards can have problems with the high AGP or PCI speed."

What they dont point out is that this is due to the same "excellent overclockability" of the ASUS motherboard. As Asus neglected to allow manual adjustment of PCI and AGP dividers on this reputedly "Extremely overclockable" motherboard. So what you get is the same dividers until you reach the next official FSB speed
i.e. :
66mhz = PCI 1/2 and AGP 1:1
75mhz = PCI 1/2 and AGP 1:1
95mhz = PCI 1/2 and AGP 1:1 (you see this is a dangerous level PCI now 42mhz+)

then
100 = PCI 1/3 and AGP 2:3
.........
127 = PCI 1/3 and AGP 2:3 (again unnecessary PCI and AGP speed)

then
133 FSB onwards PCI 1/4 and AGP 1:2 as with other boards.

For anyone with a cpu not capable of reaching the next official FSB speed grade the ASUS xUSL2 series are next to USELESS for overclocking. If your 66fsb celeron made 95mhz fsb with any of these ASUS boards you would be stuck as PCI at 42+mhz wouldnt be usable and also you would be forced to run the AGP slot at 95mhz, hardly a recipe for stability.

For the celeron 1200 had an ABIT ST6 or SOYO TISU board been used, a much more stable result could have been produced as these boards support correct PCI and AGP divider settings.

NO REVIEWS EVER POINTED OUT THIS FLAW.

Buying an ASUS board: ASUS = U ASS

Mind you, ASUS do make great graphics cards. He he.

the locked multiplier is the same on most boards.

the divider is fixed between certain speeds
100 - 132 Mhz is x1/3 = 33.3Mhz - 44Mhz
then
133 - 166 Mhz is x1/4 = 33.3Mhz - 41.5Mhz

having dividers is the easiest way to do things. and its the same on via, amd, sis and intel motherboards.

its the bane of overclockers, specially for people like me that push their system bus.
my ram can handle well beyond 160Mhz, yet im restricted to 154 as i start getting ide controller errors.

You are WRONG here!

>having dividers is the easiest way to do things.
>and its ?the same on via, amd, sis and intel motherboards.

You illustrate how POOR asus implementation is, for example on the ABIT 815 board with Softmenu 3 you can pick which set of dividers to use say 2/3 agp and 1/3 pci then choose any FSB from 66 to 200 mhz.

Also on most soyo boards there are always SEVERAL settings BELOW the next fsb grade which have the Higher settings Ratios for the dividers e.g. 90mhz and 95mhz get the 2/3 AGP and 1/3 PCI settings of a 100 FSB which is STABLE! unlike asus implementation where the dividers only change when you reach the next OFFICIAL bus speed... 100...133.
With a cpu which doesnt make it to the next FSB grade with the asus board you will be limited because of this flaw.

hmmm intrusing...
i remember my very old p3b-f was a bit like that...
set the fsb to 66,75,83,100 and then the divider.

but amongst kt133a boards it seems to be the same (or at least similar)
then again most of my expertese is for athlon mobos, not p3/p4.
and he is probably right about asus boards...
they use elevated voltages to get stability (1.80 for 1.75v core, 3.56v for the 3.3v mem)
and tweaked fsb i.e. 9x133 = 1209.

mine died a while back too.
combination of poor psu and overclocking (i think)
developed incurable IDE controller errors.

now using a much more tweakable iwill kk266 board

Asus mobo's are crap. Just built a system with a Asus mobo, no memory whould work in the 2nd Dimm slot. Tried setting Voltage and DRAM timings to no avail. Board has no been sent back and replaced with a Gigabyte Board which i've never had problems with past builds. Thought I'd give Asus a go. Wish I never bothered. Its fair to say I will be staying well clear of Asus in the the future.

@Bigdave, you do realise this thread is like 9 years old......

Perhaps create a new thread if you have a problem, rather than reviving dead threads
