so,

benchmarks.

superpi (1m): 4mins 41 sec.
osmark: (sorry jim, ive allready done it)

osmark finished well all 40-45 benchmarks. i didnt knew it will take that long. i played arround with some of them, there are some realy interesting ones! all the system seems to be stable ... no errors or page faults ... maybe there will be one day when some electrons refuse to do what they have to. ill have a look for a fire extinguisher on ebay :)


hehe. i cant post the results, because i tried the winxp activator last night .. lol. ill reinstal a new one for you, i please for patience.

after reinstalling it i will have a look on the offsets as well.

see ya soon

@Kalabok

Any chance of benchmarking with Sandra memory bandwidth and Everest with and without tweaks using 550mhz at 5.5X100fsb just to give us an idea of the increase in performance.

Thanks,

Stedman.

thank you, donpedro, as you told, the enviromental save did not change anyhing. one more mystery.

@stedman
i will post them tomorrow. but ill try to guess it - as i found out, memory performancy increase linearly with the frequency the dimms are running.
if i get 410 and 169 at 133mhz, it would be 1/4 less - 307 and 127 at 100mhz. untweaked. ok, there will be more write @100 because of faster running memory, so lets say 137.

@kalabok

thank you for the numbers! :)

I am preparing a comparison chart to show what the numbers you get are worth, not finished yet but for now I need some sleep.

@ kalabok : Glad it worked ok for you! Would have felt very badly if you had burnt something cause it was me who pointed you at OSMark- (which takes upwards of an hour to run; and tests everything in the system @ 100% utilization.). One begins to see why Epox has the reputation of having made the best SS7 boards.

here i am again,

for stedman: the benchmark result for an k6-2+ @ 550 (100*5,5) untweaked:

310read
145write
224 delay.

202 alu
204 fpu

@all: after clearing my bios i solved some mysteries i mentioned above.

1) ignore my statement sandra is changing the offsets, its not true. same as the enviromental save by wpcredit. thx to donpedro, he was right at this point. the only thing boosting up my comp up to 20% is the "dram fast encoding" setting in bios.
2) exactly this setting should be set do enabled, not auto - as i thought it would be the best. this change is switching the 6c offset to 00, giving higher memory performance. without it i get
257 read
127 write
264 delay, as it was before i started playing with wpcredit.

ok, enough of my system so far. i wonder if somebody with an epox mvp3-x board could achieve 133mhz - as i found out in internet, peaple having an mvp3g5 ran it with 124mhz ... any lucky experimentators out there?

Thanks for the results.

My EP-MVP3G-2 can't get those read scores @550

Anyway taking the board at set up defaults in bios with no tweaks in bios or wpcredit I get with Everest (K6-III+ cpu @ 5.5 x 100)

MR/MW/ML (220/112/279)

After changing Fast Dram decode to enabled

MR/MW/ML (260/122/247)

After setting Dram timings to 2225 and interleaving to 4x

MR/MW/ML (288/129/239)

After applying WPCREDIT tweaks according to Jim's KBV3+ thread

MR/MW/ML (289/162/222)

Kalabok it would interesting to see your wpcredit dump of registers. I would have thought that we would have been closer with our figures since my board is only the ATX variation of your motherboard.

Just so you guys are playing on a level field, would point out that in my experience WINXP Pro will give about 10 more points in Everest memory read results than WIN98 Se.

stedman,

maybe first checking bios settings will help. in chipset features ive got nearly all enabled, 4* memory interleave, dram timing fastest, bios&video cacheble and a lot of other stuff, i do not remember. maybe try to switch some of them on and look what happens.
and winxp pro is realy a bit faster, than win98. pc133 sdram? l3 cache?
... the wpcr matrix will come soon.

I havea EP-MVP3C (not C2 ) AT motherboard and I do not get scores at all near 200 + read or 120+ write.

I am interested in the PCR files and other info to see what improvements can be achieved for my system. I do have a K6-2 450+ which can run @ 100 bus speed = 550Mhz . 112 and even 124 mhz bus speeds can be run when External Cache is disabled , so there is some good headroom to be found.

I am running Win 98 S/E on it or XP Pro should it turn out better.
617Mhz has been achieved. Presently using it to do internet @124bus speed.

Assuming that this board has a VIA chipset, (I think it does), you can find the most complete selection of PCR Files that I know of in the "Software & Tweaking" section in a post titled "PCR Files Here". Just skip past the earlier stuff in the thread and you will find the downloads near the end.

Thanks for that info , will check into it for sure.
Yes , this motherboard does have a VIA MVP3 chipset too.
VIA Hyperion 4in1 version 4.51 installed.

Took out my 192 megs of SDRAM PC100 (which did 124 bus mhz @fastest settings) and placed in a single 256 meg PC133 CAS3 stick , put up the BIOS settings to 133/44 and now running @ 133 x 4.5 = 600 mhz , this with Bios settings set to Normal/ low and disabled for DRAM options for the 1st effort. (External cache = disabled too)

I am very surprised to achieve this as I never have ran a Super 7 system past 124Mhz bus stable. I have Everest Home 1.51 and it locks up when certain info or tests are attempted. Will re-install and do more tests through-out the week.

If you use CPU Cool you can get it to do 133/33 which should enhance your stability though not your test numbers.

im back.

@ dasman2: im very surprised you could get your k6-2+ 450 to run at 617mhz! its a mystery for me so far, how you guys reach overclocking till 30% ... with acz cpus! me i got an 2+ 550acz and an III+ 500acr, maximum overclock i reached was +70mhz. iffy friends, i guess.

finally i solved the error message prob. i did not knew, wpcredit searches for the right pcrfile automaticly. copied to the desktop the programm only shows numbers at start, error messages everytime i try to load the proper pcrfile. starting it in its own folder (where i downloaded the pcrs) gives no error message anymore - lol.

@ stedman: copied this info from cpuz registry .txt file. it is set to give the best benchmark results for me. i hope it helps you:

@ Kalabok : The K6-2+ 450ACZ and the K6-2+ 550ACZ are both designed and manufactured to the same specifications. The only difference between them is the engraving on the heat spreader cap and that AMD thought, (on the basis of testing a few specimens from various parts of the "wafer"), that those designated 550s would make better processors. As a result of being the same they are both capable of about the same top speed.
