i seemed to have made a mistake somewhere with the pinmod.
my chip originally defaulted to 1.296v, i tried the pinmod vid4 to vss, now i have 1.46v showing up in the bios and in cpu-z. shouldnt it be closer to 1.6v?
my setup right now is
1.7ghz dothan
aopen 855gme
512mb tccd
ti-4200
using stock cooler
priming at the moment at 2.7ghz (17x159), 2.8ghz superpi 1m stable @ 1.46v
using 3:4 divider so tccd currently @ 212mhz 2.5-3-3-7
That's because you're using a 533 Busspeed Dothan :DQuote:

The defaulted Vcore for a dothan chip (400 busspeed) is 1.34V :)Quote:

I also had Vcore fluctuations. I seems not to get stable.
When I wiretricked it to 1.66V sometimes i only get 1.58V :stick:
i know, but does that make it not a world record(???) if it is? ;)....it's not like a new P4 or A64 beats an older 3D bench score because they have higher or better architecture ;)...it's like saying the 6800s SLI WR is not a valid WR because it beats older 9800s ;)....Quote:

it should be a dothan 400mhz cpu.Quote:

edit: i started screwing around more. did vid4 to vss, vid2 to vss, vid3 to vss - now i got 1.58v or 1.59v showing up. :confused:
You should get 1.66V with vid2/vid4 connected to vss.Quote:

I don't think it's only you, someone who has a DFI also got this fluctuations. Nothing you can do about :slap:
just finished benching at 200FSB, wheeeeee...P95 stable for ~6hrs, Spi anti-cheat 1M run (while p95 is running *lol*) and temp never breaking 44c at full load...

nice :)
I also have a 200Mhz fsb shot, the max fsb really depends on your cpu ;)

You beat me by 0.36Mhz :D
doesn't it depend more on your chipset??? :)
I don't think so, i had two 755s, the first reached only 180Mhz, and the second 200Mhz (lowered multi, so not a max frequency issue), I didn't change anything on the mobo between the both tests...
Maybe you got a dothan that wasn't good enough for a 533 busspeed dothan :D. I was convinced that everyone that has a 400Mhz dothan can't get across 180 :).Quote:

Oh common, you can do better that this :D (with you fancy cascade)
Where's the 20 x 200Mhz screenshot :p:
I'm trying to go farther, I'll be testing all day long tomorrow. For now, the best I did is only 20*160, I'll try 16*200, it should be way better :D
my cascade is not fancy :o only crappy :D this ****ing CO2 always clogs my evap :(
just a quick question i bought a dell notebook witha 745 dothan at 1.8ghz can i oc it to 2.0ghz??? if so how can i do it?? with clockgen??? how high can i go without uping volts for vcore and ram?? can i change latencies???
but what i meant is on air, stock everything (cooling, vCore, vDimm, totally unmodded board) =)...mine runs on air and stock everything =)...so i was shooting for a WR on that category not on uber leet heavily modded board with extreme cooling :banana: :banana:
and nate's 533Mhz dothan didn't past 170FSB as well: http://forums.legitreviews.com/viewt...33aab53493b2d5
and that's with a vcore pin modded Dothan@1.6v =)...

Tyrou, yep, here's my old post (quoted *lol*) so I'm just thinking if I should brag about it hahaha....i "bold" my mention of stock everything ;)...

yay, thanks Tyrou, posted it at Xtreme OCing area =)...
i tried the vdimm mod, pin6 50k trimmer to pin4. the highest i can get my vdimm to is 3.31v. Is this correct?
because im wondering how lardarse's friend or lardarse(can't remember who) pumped 3.9v into their bh5's.
I think you have an Aopen.Quote:

1) Use an OCZ booster -> the downside is that you can only use 1 dimm. Or benching this is not a problem. Cause with one stick I reach higher FSB than 2 dimm's together. Although they can reach the higher FSB each seperately :stick: .
2) Mod your PSU if yours allow it (if you have a Vsense cable on the 3.3V line (normaly it's an orange cable)=> for more explanation search the Hell-fire's PSU mod on the forum), cause the Vdimm is juiced with the 3.3V-rail.
If you mod the PSU and set the VR of PSU on 3.9V, you can can adjust your Vdimm with the VR of your Vdimm mod :)
Some PSU already have VR's to set the Voltages, eg OCZ powerstream line ;)
I hope your modding :)
thanks vegeta, i have a fortron 530w w/ adjustable pots coming tomorrow. right now im using a antec 300w psu :(
this is what i believe so far with my setup.
with my 1.7ghz dothan
chip maxes out at 2.85ghz, primestable at 2.75ghz. i think it would prime higher if i changed coolers.
my bh5 using 3.3v at the moment maxes out at 255mhz.
so far my best superpi1m is 30s
I dunno how your dothan will oc.
These are the result i got with a 1.5 Dothan. Not too shabby huh :D (and all this on aircooling :woot: )
Unfortunately, i sold that setup. And bought myself the Alviso board. I kinda regret that I sold my previous board :slap:

Are you getting anything out of your current aopen board vegeta?
Hi, I tried the pin-mod again (board back from rma), but it says 1,360 V instead of 1,6 V. I did the mod right.
