More exactly here.. I don't expect this benchmark to be comprehensive. I think there isn't a bandwidth difference between 2812 & 2815.

[Holst]

I wouldt recomend sandra for a usefull performace comparison.
Its just too innacurate.

Try PCmark memory bandwith or SuperPI next time BNN

You might also want to try a WPCREDIT'd 2812 and 2815, thats the fastest for me.

[BNN]

About Sandra it's true. My opinion is same but i haven't enough time to make more test. I promise the next time to compare the memory bandwidth with PCMark.
Can you tell me the settings you're using with WCredit? I use this settings with my test OS (Win98SE), but know i'm not absolutely sure if i have activated them. That was my settings previously used with 2312.
55=84
6A=FF
6B=F0
93=FF
94=5F
96=F9

If you use something different can you tell me?

Thanks for the heads up ET.

Already d/l only haven't flashed yet....... reason awaiting some good cas2 PC3200.

[Dagalidis]

This BIOS is almost the same as 2812 regarding Performance.....But this new one recognizes new XP2400+ and XP2600+...

When overclock over 1900Mhz BIOS show me XP2400+ and this mean probably XP2300+ will never come out or will late....

Dimitris.....

This bios is not correct. AMD has altered their performance marking #'s slightly. The 2400 runs at 2000 mhz and the 2600 at 2113. I am sure when epox picks up on this, the bios update will change .

[B1aderunner]

Why does the Magic Flash utility not find this new bios if it is official and if it can't find it is there any way to make it use it if I download it seperately?

I can always flash it using the boot disc method I just fancied trying out the new Epox utility

It will probably take a whyle for the new bios to be added to the magic flash utility.

The Xp ratings on this bios are correct. XP-2600 runs at 2.166mhz not 2113 (how can you make 2113 at 133fsb ? )

Although you are correct that AMD have altered the XP ratings calculation. Using the same calculation use for Xp-2000 and less the Xp-2600 should be 2.066mhx not 2166 so amd must have dropped the rating by 100mhz.
I suspect that AMD may get this back with the 166fsb chips.

Can somebody tell me with 100% certainty the clock speed of the Xp-2400 chip ?

[Alexandrus]

Holst, actually the XP2600+ runs at 2133MHz, not 2166. It has a FSB of 133MHz and a multiplier of 16x, so you do the math.
2166 is impossible to get with multipliersincreasing in 0.5x steps and FSB of 133.

[Holst]

LOL

Opps typo :P

[Alexandrus]

Didn't mean it as criticism.

OT, Holst, ET didn't want to tell me, maybe you can if you know, what are the new P4 baords that will be launched by EPoX in the near future ?

[AMD FANZ]

when compare to the 2619 bios, 2815 bios seems much unstable than before. my mb updated to 2815 2 days ago and it has already auto reboot my system twice when i playing CS.

Athlon xp 2100+ (138*13) @1793mhz
epox 8k3a ver.1.1 bios:2815
cakII 38
abit GF4MX
SB Audigy
40GB Maxtor HDD

[Alexandrus]

Weird stuff, my mobo is prefectly stable with 2815 and I play JK2 all day long.

Sounds like a possible issue with your OC, AMD FANZ. I have yet to encounter instability w/ any of the 8K3A BIOS's unless I had pushed my components too far.

Exactly, the 2312,2812,and 2815 bios will not go as high as the others, this is to be expected due to the CPU fast command decode and ram timings, you get better performance at a lower speed.

[AMD FANZ]

Thats what I thought too. I will try this bios again w/o oc to see if it is stable or not.

The bios reads my 1930mhz as xp2400. xp2400 is 2gig.

Grrrr.... I cant get my CPU to 2gig to testthat :P

Thanks.

It seems AMD have dropped the rating down for the 2400 as well, as expected to be honest.

I thought it was:
1333 = 1500+
1400 = 1600+
1466 = 1700+
1533 = 1800+
1600 = 1900+
1666 = 2000+
1733 = 2100+
1800 = 2200+
1866 = 2300+ (not sure if these will exist)
1933 = 2400+
2000 = 2500+ (not sure if these will exist)
2066 = 2600+

I know they're gonna get creative the future, but afaik, this is it.

AMD have dropped the ratings hence my question.

Xp-2200 is 1800mhz but Xp2600 is 2.133 (definately), as you can see they have rated the 2.133gig part one rating too low (on your linear scale)

Exactly where they have dropped that rating is between Xp-2200 and 2400 (if XGman is right about the Xp-2400) , I doubt we will ever see a Xp2300 CPU.

So AMD have corrected the ratings to account for the CPU hitting a plateau (limited by bus speed mainly)
Id expect them to grab that 100 PR back once they go to 166fsb
