Now those voltages are just insane... lookin for short lived mem that for sure. Also the limitations of the PCI bus bandwidth with the KT333 chipset is appalling

You are correct in the fact that the high Vmem will reduce my ram’s life. I will give you that. Life of a stick of ram is what 10 - 20 years under optimal conditions? As long as the ram is kept cool even if the high voltage reduces its life by 75%-80% it will have well served its purpose. How many people do not upgrade their performance/gaming rig at least every 2 to 5 years? I do not know where you got your info but I would put my Abit KX333 up against your MSI or any other AMD chipset any day. What are you basing your conclusions on? If my PCI, AGP and mem bandwidth is less then I need to change. I have seen nothing yet to prove this as fact.

Please enlighten me so I can improve my performance.

mbrock, via 266a and 333 have excellent memory performance, and good AGP performance....But the PCI performance not very good, most games and benchmarks will not show these limitations.

You will notice the difference between a kt333 and a sis745 system when you are using multiple PCI devices, eg RAID controller and a capture Card...in fact via chipsets limitations show there limits just using a RAID controller.

and crackling soundblaster's arn't fun either

RAID perfromance looks fine on my A7V333...

Maybe, but my SB live has not cracked and popped sisnce my old KR7 and only because I had my PCI bus so far out of spec with the FSB at 195 the PCI was at 48.75. My KX333 has not had those problems on either the SB or my NIC.

18+ years OCing computers and experience as an EE in doing so... where do you get yours?

BTW as was already stated the 745 chipset whips any VIA chipset arse. You should realise that not everything based on today's best bechmarks will test this... just like peak fps on a GF4 doesn't mean it doesn't stutter or lacks when the going gets tough.

**Dr Mordrid** · 1 July 2002, 07:52

Where the PCI performance difference really shows is when you have PCI devices that require a high bandwidth like the RT.X100.

On the KT-266/333 systems this chokes, often causing playback stutters and the downright failure of some functions like realtime export to HDD or IEEE-1394 when you have multiple effects applied to the project.

This problem on the VIA chipsets is so bad that Matrox is not recommending VIA KT-266/333 chipsets for use with the RT.X100.

Where the SiS chipsets shine is because they do multi-threaded I/O plus they give each PCI slot it's own DMA, I/O etc. etc. to extend the bandwidth.

It works spectacularly as even an el'cheapo ($65 USD) ECS K7S6A (SiS 745) can run the RT.X100 full tilt & then some while a much more $$ board like the Gigabyte GA-7VRX (VIA KT-333) falls flat on its face.

The SiS 645 chipset for the P4 performs similarly and it too has multithreaded I/O etc. and is recommended by Matrox for the RT.X100.

Dr Mordrid

Thank you that was the answer I was looking for. Not some off the wall info like "BTW as was already stated the 745 chipset whips any VIA chipset arse" that absolutely gave me info on what I was asking. Thanks again Dr.Mordrid.

No I am not an EE and I have not been OCing for quite 18years but I do I do a pretty good job of OCing myself most of which I learned the hard way through trial and error. My KX333 suits my needs perfectly it is built as a hobby machine Benchmarking and Gaming. It performs those two functuions as good as any. I would hope after 18+ years of OCing you would get more than 123mhz on your OC.

Excuse me if I offended you. I used to always use M cards and used my G400 max until I was dissapointed with Matrox not putting out a true performace card last year. Nvidea and ATI was my only choice. I hope the 512's performance increases as new drivers are released if so I will return to Matrox.

**Greebe** · 1 July 2002, 09:06

You didn't offend me at all, but it's obvious your not reading the other threads discussing this. It's you not me that should pay attention... it's 186 mHz (and stated in my sig at 184) not 123!

**mbrock** · 1 July 2002, 09:37

Excuse me:

"OS: XP, XP 1800+ @1656"

XP1800 stock = 1533mhz
1656 - 1533 = 123mhz

You are correct I have not read the other threads. I come here to MURC mainly to keep up on how Matrox is doing and what new is on the horizonfor them. I came across this thread and decided to post my Sandra mem score. I was really looking for bench marks on the 512.

**mbrock** · 2 July 2002, 17:02

last on

PCI bandwidth may suck but you have to love the memory bandwidth on the KX333

**Greebe** · 2 July 2002, 18:22

Regardless mem speed cannot make up for lack of bandwidth.

And oh your making fun because I'm not pushing my cpu beyond a 123mHz OC?

Did you possibly think it's because I haven't bothered with trying for more as I'm busy beta testing Parhelia?

Noooooooooooooo

**Silencer** · 2 July 2002, 19:30

I don´t trust Sisoft Sandra 2002.
The memorybench shows a bandwith around 1200MB/sec, but I use a i440BX with a PL-iP3/T and a P-III S 1.13GHz @ 1.28GHz (150MHz FSB).
Sisoft Sandra 2000/2001 show the correct score of 590 to 600MB/sec.

**mbrock** · 2 July 2002, 19:40

Silencer

I do not normally use 2002 either but that is what this thread was for so I upgraded my 2001 to 2002 just to compare Oranges with Oranges. If you disable the buffering crap the score in 2002 is about the same as 2001.

**Silencer** · 2 July 2002, 19:42

thanks for this info.
however, now I use wstream for memory benchmarks.
