Question for compuwiz

[marooned]

Hey there!

I've read some of your posts about those incredible chips you have getting up to 1.5. My question is at those speeds are you able to run your video card at 4x? I am finally satisfied with my 1gig doing 150x9 = 1350 but I can only do it with agp4x disabled. Keeping in mind that with this setup it beat all scores I had when I had my chip running at 148x9.5 = 1406. Thanks in advance!

Tough question. Frankly, I use trash video cards in test systems. (ATI Rage Pro, Expert98). All I really want to do is get enough video so I can start the CPU Stability test.

I'm afraid I cannot answer that question, but my guess would be, if you load the system more, than it would be at 2x, you are going to expose a weakness, or instability, if you will.

Thanks for the reply. I found it extremely frustrating getting my system stable because I could sometimes not pin point the exact cause of instability. Like sometimes my system would be fine for like a day and then the next day it would just crash while surfing... I don't think it is possible to run at agp 4x with a bus speed of 150 or higher...

Well, in looking at your config, one glaring thing is your voltage. I think if you would push that up a little, you may be able to stabilize it. (try 1.8-1.85v) If you do this, get rid of the thermal pad, if you have not already and get some Arctic silver. You cannot run both, they'll negate each other.

What it sounds like is happening to you, are the things that happen when there is not quite enough juice. Also, what is you I/O voltage. You might go up a point or two there too.

Everything compuwiz added is great advice but I just wanted to offer my own personal experience. I just bought a Leadtek Geforce 2 GTS Pro 64 meg card and it would not run at 4X on my "old" Asus P3V4X mobo.

i tried everything even running the CPU at default speed did not accomplish it

I could not enable fast writes also.

I did a search on this BBS and found out this was a problem with the way the via chipset handles the voltage on this particular Motherboard.

You may want to conduct your own search to see if fellow owners have had the same problems.

The Video card was extremely also prone to crashing when I was overclocking above 133 MHZ which was a real bummer for me because I know my CPU can run at 150 MHZ with no probs at all.

So I decided to switch to a Asus CUSL2-C mobo using the intel 815Ep chipset.

So far so good the video card stability is MUCH better and I am also running 4X aGP with fast writes enabled.

the only problem that I have with the motherboard is the Asus probe likes to "freak" out and give me 0 RPM reading on my fans?!?! not sure what that is all about yet

Overall I am happy with this mobo though and I hope you find a solution to your problem.

the Asus probe is crap with my A7V133...does the samething with my fan speed ....

Compuwiz, tried everything voltage wise... even tried the driving value for agp to no avail. First thing I did when I got this guy home was remove the thermal pad. Thanks for the info man

marooned,

I got a 1.2 from compuwiz and also some of his Infineon 256MB ram. I am currently running my IWILL KK266 (non-raid ver 1.1) at 150x9 with my Creative GeForce2 having AGP 4x AND Fast Writes enabled. This setup is ROCK SOLID. I am running vcore 1.85 I/O at default 3.4

I tried for a week to get my ABIT KT-7A Raid stable, but I had multiple problems. It REFUSED to go over 142mH FSB, and was constantly locking up for no reason at all, even at default speed.

I got sick of messing with it, so I shut my computer off, yanked out the ABIT, put in the IWILL KK266 and installed ALL of my PCI/ISA cards AND USB devices, and booted it up. The IWILL had absolutely NO PROBLEMS dealing with all the equipment in my machine, and had been rock solid ever since.

I've got another customer I am getting ready to send a third chip to, and we cannot seem to get him the same result as I am getting here. He has an Abit KT7a Raid, which is what I have tested all, except his first chip on. I think my Abit board works fine, although like you stated, I get better results on the IWill.
I am beginning to believe he got a board that is a touch flaky. What I am testing here at 1450+ are going 1.4 for him. It's been frustrating, since I know these chips are solid.

He also has my Infineon ram.

Steve,

I would be almost 99.99% positive the ABIT board is causing his problems. I have built a LOT of machines, and NEVER had as many problems with a MB as the ABIT KT-7A Raid I bought. I spent at least 20 hours trying to get it right to no avail. Maybe I got a bad board too, but I could not get it stable even at default speed. After having such good luck with the IWILL KK266 I'm not even going to worry about why the ABIT wouldn't work.

Thanks for my 1.2 at 1.35 Steve, I'm currently running it at 1.425 (150x9.5) rock solid and am going to push it a little more tonight.
