815 Chipset Tweak Utility?

[cbman]

Anyone have/heard/seen a tweak program for the 815 Chipset at a hardware level...?

Just a thought.

Damn... I have been looking all over for something for the past few weeks and I never thought to ask here... I finally do it and it comes up with something promising after less than a few hours.. LOL

Time to go play around...

As far as i can tell they are talking about WPCREDIT & WPCRSET by H.Oda.
Both excellent programs ... however there is another program which starts from your autoexec.bat ( or any .bat file ) which is called StuffPCR which uses bin files to program the chipset prior to windoze bootup.
It gives the same performance boost as WPCRSET 'cause it programs the same things in the i815 chipset as WPCRSet, but it doesn't require a .VXD file.
With StuffPCR you can get optimum memory performance and AGP x4 with bus speeds above 140 Mhz on i815 chipset and optimum memory performance on P3V4X boards ( VIA Apollo Pro 133A chipset ).
The thing is, i don't recall where i got it from, only that the link was on one of the pages on the forum RAGS pointed you to ... however i will gladly mail it to you if you want it !

[arbymo]

does StuffPCR works for the BX chipset too ? if it doesn't .. is there any other program that does ? specially for the memory interleave thing; as it's not an option in my BIOS.

[Kosh Naranek]

StuffPCR doesn't support BX chipset ... sorry
WPCREdit by H.Oda doesn't have a *.pcr file to support the BX chipset but maybe it's supported without a PCR file ....
Check it out @ www.h-oda.com under download.
To tweak settings automatically you need WPCRSet, which can set values you have found using WPCREdit, automatically every time windoze boots.
However H.Oda doesn't have WPCRSet on his page anymore but you can get it at www.viahardware.com

Or you can try the forum at www.overclockers.com.au ... part of the link RAGS suggested.

Hey All.

I was playing around and didn't find too much extra that isn't in the Asus CUSL2's Bios.

About the only thing is the Memory Interleave that I can't seem to find the entry for.. I think I am going to download that 815 Chipset Whitepaper.

The whole reason I am working at this is a strange peculiarity that I ran across a while ago... I use to pull almost 350MB/s mem in Sisoft 2001 and now its down to just over 250MB/s

I have tried everything but it just won't go back up...

Sisoft doesn't display anything about my memory interleave at all. (not where it should anyways...)

Oh well...

Time to go read some Intel.. LOL

Ok.. I have read the GMHC 815 Whitepaper and guess what... only one mentioned instance of interleave...

110 = Mode Register Set Enable. In this mode all processor cycles to SDRAM result in a mode
register set command on the SDRAM interface. The Command is driven on the MA[12:0] lines.
MA[2:0] must always be driven to 010 for burst of 4 mode. MA3 must be driven to 1 for
interleave wrap type. MA4 needs to be driven to the value programmed in the CAS# Latency bit.
MA[6:5] should always be driven to 01. MA[12:7] must be driven to 00000. BIOS must calculate
and drive the correct host address for each row of memory such that the correct command is
driven on the MA[12:0] lines.
Note that MAB[7:4]# are inverted from MAA[7:4]; BIOS must account for this.

Hmmm... maybe I will scope out a few more whitepapers... see if I can dig up anything!

Well after some searching on Intel's Developer Site I found out that the 815 is labeled as having N/A for Memory Interleaving... I don't know what the difference is.. but the BX is labeled as NO... so it could be good.. could be bad... time to look around some more.

Yeah, interleave will help a lot if you can get it enabled.
Unfortunately there isn't much else you can do to help the 815 chipset, as its really a dog to start with.

Hey cb,

Your drop in performance didn't happen to occur after you raised your FSB above 140, would it?

If I could push this 566 CuMine to 140MHz FSB I would be in Geek Heaven

No.. I am not sure when the drop occured... more than likely after I flashed my bios to 1006 Beta 5 (CUSL2)

Flashing back to 1003 didn't restore the throughput though.. so maybe it was just a fluke... but fluke or not I still know this computer is able to do it...

Still checking into it.

Hey, goto www.cusl2c.com and look in their forums they have several threads on how to get the most out of your i815E's memory performance.


I had a coppermine 550E that was easily able to hit 165 FSB, so I am quite surprised that your 566 can't make the minor jump to 140.

Here's a good thread to start with tweaking your memory performance using the tools you already have.
