Can G400 handle 133MHz bus speed? (tomshardware)

[LAMFDTK]

Come on ...Can anyone here agree with this guy? Have you read his other work? This guy suffers like the (American Basher) Tom Pabst.
He comes to the MURC and tries to defend his findings that we all know is a bunch of crap.
He is a bit player and not worth the effort to educate. The Nvidia product will always rule. **<cough>**

LAMFDTK,

sad, but true. In Germany we would say he is a "Schmierfink" (maybe somebody translates this :-)), but definately not an objective online-journalist.

In my case, it is all true. I have a 7KXA with a G400 MAX and it will not overclock over 100Mhz FBS. It took me a week or so to get it to work at AGP4X. The good news is that locks or reboots when loading windows not before. Seem like a problem with the G400 drivers not the hardware.

Hello,

If I could get slip in here for a minute I'd really appreciate any advice any of you could give me on overclocking.

My current specs are

P3 500 Katmai
G400Max
ASUS P3B-F
2x128 DIMM PC100 RAM
2940U2W SCSI controller
Quantum Atlas IV 9.1GB 7200rpm SCSI
Pioneer 6x DVD SCSI
SBLive! Full
Real Magic DVD Decoder
Linksys 10/100 Etherfast NIC

I've got an average case and all my fans and sinks are retail but I have a 12 CFM blower fan in the PCI slot 1mm under my AGP. Can anyone give me any advice for overclocking? I'm sort of new to it. I have my board at 110 right now (CPU 550MHz) and I haven't noticed any instability. My RAM is only rated at 100MHz so I don't really think it's a great idea to push it any further. One question I have is - can I overclock my G400Max independantly for the rest of the board?

I'm going to be upgrading to this in the near future; this system is just asking to be run at 133MHz. I've read all of your posts (hope you don't mind) concerning the 2/3 AGP multiplier and the question of stability, I do however like to keep a margin of "safety" by holding back a little on the o/c, which returns me to my question - can the AGP be clocked independantly.

Hopefully, I'll be getting an Alpha CPU and a Lasagna AGP cooler soon. I guess a new case and PCI fans wouldn't hurt either.

Thanks, in advance, for your feed back.

I wouldn't toss the PC100 before you try it at the higher mhz first. Depending on its quality, it may do fine there, especially at 3-3-3. With your current setup, you are probably near the max. I think 620 is about as fast as those CPUs will go, and that with good cooling. Have you tried going faster?

If you do get new RAM, make sure a single 256MB module will work OK on your board. If it's like the Soyo +IV, you may need a registered DIMM to go that large. That can be expensive.

Similarly, I wouldn't throw money at cooling before you find you have a problem. One thing to check is whether your board will allow 3.5v on the 3.3v circuit. The Soyo +IV does this by default. This helps stability quite a bit when running the AGP faster.

As for your question on the AGP, it cannot be changed independent of the front side bus (fsb).

Reading all this I decided to try just how much can my G400DH do.
Normally my sistem works at 100Mhz FSB(Celeron300A@450) with AGP set to 2/3.
At 75, 83 Mhz FSB with AGP set to 1/1 none problems, while at 100Mhz(1/1) Win98 would boot and work just fine in 2D, which is not the casee with 3D apps.
After about 1min. or so 3D apps. allways crash my system.
I don't see any reson why it should't work at 133Mhz FSB with AGP set to 2/3 (133*2/3=88,6), especially don't see reson not to pass posting.

BTW My friends Celeron366 won't go 550 on his ASUS P3B-F, while on my ABIT BX6r2 with no problems.
Cooling was pretty much the same, and CPU fan/sink identical......so much of ASUS overclocking stability.

Sorry for multiple posting.
I had some problems with slow connection.

[archangle]

Umm what exactly is the 3-3-3 No's all about?

Whenever I tried to up the FSB from 104, it would reset to 100 whenever the computer was reset (before and after multiplier increase)

Would changing the AGP multiplyer to (2/3) help? if so how would I do it?

Athlon 500@733 (7*104)
Asus K7M
128MB pc100
Matrox G400 32MB HD Vanilla @ 301.5Mhz + memory tweaks + fan
etc

[Goc]

OK.. here's my setup:

PIII450@550(124MhzFSB)
ABIT BH6 rev.1.60
generic PC100, 7ns
G400SH 16Mb
WDC 8.4Gb
yadda, yadda

No problems whatsoever...
At 133Mhz machine boots fine, but it hangs when it enters Windoze... I think it's more of a processor issue than something being wrong with the G400.
And fellow murcers, don't crap all over Silvino for not giving Matrox credit... guess it's one of those cases when two components simply won't work together, yet in any other combination they deliver just fine...

[WayneHu]

No problem with 133 MHz FSB ...

Even at 140 MHz FSB...

150 MHz FSB... Can Boot Win98, but not stable...

The CPU is Retail one (SL3V5)...

However, My RAM is not good enough...
If the FSB >= 133 MHz, I have to use 3-3-3...

A couple of things for Silvino, if he is still checking this thread:

You were using a beta version of bios 1005, which I would discourage. Either try 1004, or the final 1005. There is reason to suspect that the ACPI support might not have worked correctly in the betas. Second, I had to reinstall win98 after flashing to 1005, though that doesn't necessarily relate to your problem.

The fact that you aren't posting (upon boot, not to this forum ) is reason to suspect the mobo bios. Or, perhaps the vga bios. The latest vid bios is available here: http://www.matrox.com/mga/drivers/bios/home2.htm
