Basic FX59xxx bios changes

[gianvito]

I will follow you! I will try 56.72 and will say you the result!... but I think that if at 920Mhz get artifacts...it will also get artifact with 56.72...We will see...

[gianvito]

Well...these are the results:
53.03 - 5570
56.72 - 5530
61.77 - 5850

Then? The 61.77 is the best performance driver...but you say that it's unstable...mah...I have no problem...then NO OVERCLOCKING gain with 53.03 or 56.72 drivers and...if I could overclock some more with that driver, performance will never be as 61.77 Driver.......
What about 43.03 Leaked driver? Have you tested them? And what about Omega Driver?

NOW....I'm locked!!! Can I send you my original bios and my modded bios so you can verify if I set Latency correctly?

I have PM'd you where to send bios's !

And forget 4xxx drivers, they are too old to be of any real use for current games.

Thanks Jimmor, I used your tips to mod my bios, my memory went from 770 to 830 and my 3dmark2003 from 6500 to 6823!

[gianvito]

But...I only here haven't crossed the 6000????? :retard: I have AMD 3000+ NON OC....and 512Mb of Corsair 2700........Now I will try the new Jimmor's bios...

[gianvito]

WOW! Finally 6100! But....WITH 2 BIG artifacts....and in the games the artifacts come and come!!! I saw that you have setted my memory frequence at 900 for first 8bit and at 950 for the rest....why??? The artifacts are here!!!!!!!!!! :retard: ... NOTHING TO DO....ARE MY MEMORY ALREADY AT MAX???? but... It isn't NORMAL! Same frequence at Normal and Relaxed timings.......

[Daneel Olivaw]

Gianvito, calm the h* down... What little points you're trying to gain won't change anything in your games, you're better off with a stable card.

And quit yelling!

[gianvito]

Sorry Jimmor...I saw a stupid thing! That 900Mhz was the 450Mhz of Throttling Mode that you have setted...... :lol2:

[jimmor]

No prob's, thats what my 59xx bios moding guide is for.

good result !

If you are getting artifacts, then try memory at 940 or 930 ?

Only reason I settled for 950 with moded bios is because you told me that original bios was totally stable at 900MHz ???

[jimmor]

Sorry Jimmor...I saw a stupid thing! That 900Mhz was the 450Mhz of Throttling Mode that you have setted...... :lol2:

If you haven't yet grasped what your are doing, in spite of my 59xx bios modding guide and my other input, then you should not be involved with bios mods !

[gianvito]

I have grasped all...and I DID all that you said in your guide...but without results...with your bios I still go at 900Mhz...at 910 I get artifacts.....

[jimmor]

THEN you lied and/or exagerated far too much about getting 900MHz stable with your original unmoded tight timings bios, because it is not possible for a unmodified and modified bios to get exactly same overclocking levels !!

So the conversation stops here !

[Daneel Olivaw]

What's the absolute slackest latency you know of for a 59xx's memory? (just curious, I'm quite satisfied with my current modded bios, thanks to you Jimmor.)

I read through part of the guru3d forum... but all I saw was 43 instead of 40, what's your thought on 43?

[Daneel Olivaw]

Have you ever heard of modding a motherboard's bios (P4P800) to slack latencies on ddr ram? Slacker than 3-4-4-8?

I know I bombarding, sorry, do you know how to slack latencies on a ti4200?

Does someone need a modded -.rom- for a MSI 5900xt with 2.8 ns ram?

I think I'm done now... ;)

The memory latencies/timings in a 59xx bios are a two part function. The first involves the "43" you quote, which is actually part of a 8 bit word, and is the normal setting for the higher series 5900nu and up cards. The second involves a larger binary string set adjacent to the speed tables as identified in my guide. Both can be set slacker, but normally nobody chooses that since it is effectively reducing performance. And, no point arguing that you can always set speeds higher to compensate, when the memory chips used are not capable of supporting high enough speeds to do any good; other than maybe cards with 2.2ns chips or better. But then issues of adequate thermal control and designed in protection of the gpu and memory chips comes into the equation. Unfortunately many of these cards, especially the cheaper designed XT types, just aren't up for very high memory speed and stress conditions !

How much slacker and what benefits or otherwise it would achieve with any of the 59xx cards however has not been investigated to my knowledge.

EDIT:

And for interest, trials have shown that the "40" value gives slightly better bandwidth than the "43" which will actually allow slightly better memory overclock. Its mostly a matter of adjusting the diff memory timings to the performance sweetspot for your particular card. Just depends how desperate you are for that last bit of performance ?

I personally prefer to set timings to give best with lower than max speeds, in a probably misguided belief that this will put less overall stress on my card?

[jimmor]

Have you ever heard of modding a motherboard's bios (P4P800) to slack latencies on ddr ram? Slacker than 3-4-4-8?


No, but why would you modify the mobo bios per se, when the settings are usually available as a user change option ?

Also, mobo's have limitations as to what they will allow memory to overclock to, before stability issues jump in !


I know I bombarding, sorry, do you know how to slack latencies on a ti4200?


Sorry, but at the time of using my ti4200, I never had any interest in improving its memory performance other than by overclocking. But I did find I could improve stability at higher speeds by flashing with a ti4600 bios. Which was only possible as my Albatron ti4200 has same memory chip type as ti4600.


Does someone need a modded MSI 5900xt with 2.8 ns ram bios?


If I hear of someone, I will let you know.

Moving on to a 6800 then, are you ?

[Daneel Olivaw]

nonononononononono, not offering the card, just the bios. ;) I love the card too much!

I wanted a cas latency on my ddr that would actually be slower than cas 3... It would allow me to push my fsb closer to my cpu's max of 4x283 (fsb1132), instead of 4x266(fsb1066).
Just a crazy thought.

[jimmor]

nonononononononono, not offering the card, just the bios. ;)

My mistake !

But just to confuse things worse, experience has shown that all cards, as far as overclocking is concerned, needs to be considered different, even when from same manufacturer.

This has been an ongoing problem with sample modded bios's that are hosted at guru3d for anybody to use. All settings with these were based on users experience, however many people with same cards found they could not use them stable at same settings. Which therefore became one of the reasons I posted the bios modding guide, so that everybody could then do their own thing for their particular card.

Not sure what your mobo's max settings are, but I suppose you tried setting the other params more relaxed, like 3-6-6-10 ?

[Daneel Olivaw]

I'll start a thread in motherboards and cpus.

Most relaxed on P4P800 is 3-4-4-8

[gianvito]

Jimmor I newer saw that your guide sucks...but I don't know..my card is abnormal.......!
For Daneel Olivaw...if you set memory timings too high to increase frequency you will go SLOWER then when you have low timings and low frequency....you can bench it...so Set timings as LOW as possible...CAS LATENCY from 3 to 2 is VERY good...better then 333Mhz to 400Mhz!

[jimmor]

Same on my P4C800 !

And, hopefully the new thread will catch the eye of someone who is into mobo bios mods ?

EDIT:

You could always just purchase some faster memory, like PC4000-4500 ??

My 5900XT been running perfect as a 5950Ultra for ages now. I've got it cooled and it's 100% happy. I get 3Dmark03 score of over 6000... not bad for a 266FSB rig....

THX jimmor... j00 teh m4n
