**The ASrock 939dual-SATA2 (ULi M1695) thread**

ok guys
there is a new asrock bios released v1.60 with a new agp FiFo setting ? to improve results with agp cards

http://www.asrock.com/support/download.asp?Model=939Dual-SATA2

i also have removed my vcore vid4 mod and applied the vcore vid3 mod
now i can select 1.35v in the bios to give an actual 1.55v and don't suffer from the not posting problem some of us have had with trying to boot up with 1.15v selected in the bios (this will make sense to those having probs with vid4 vcore boot and revert to auto all the time)

hope this is useful for y'all

i have 2x512 geil value and up until the weekend when things when awry they were running rock solid for a month at 230 (ddr166 divider) with the rest of the memory settings on auto

Thanks for that and thanks for the heads up with regards to the new BIOS.

Nice heads up. :)

I am on PCIe now but it would be great for someone to do a benchmark on an AGP card before and after with this bios. :)

Who will be first?? :D

too late for me, I already bought a PCIE to replace my low performing agp
:o
 
Ok just updated to bios 1.60 no probelms at all noticed the AGP setting in bios and says for Nvidia cards fifo bridged or somthing like that gonna go and do some testing

Ninja

Edit just got this from the ocworkbench forum this was posted about what this new option in bios means:
"P2P In AGP is the device FIFO are handled by 16 quadwords in and out thru the buffers. these buffers are p2p device.PCI to PCI. A deep P2P FIFO changes that from a 16..to a 32 pipeline.. this will increase the AGP performance twice fold."

No change in my 3DMark05 score, but as ninjapilot posted, this is for Nvidia cards.

I enabled it however and ran the test but it didn't make any difference to my score. My system wouldn't restart though, I had to press my reset button; I've now set it to disabled and haven't had any restart issues.
 
9441 in 03 with the option enabled.

9473 in 03 with the option disabled.

A64 3200+, 1GB DDR 400 kingston ram dual chan mode, 6800LE 16,1 6vp

Everything at stock.
 
Well, looks like it isn't going to resolve agp preformance (if there IS an issue there, jury still out on that one?)

What the heck, nice to see that "people" are still working on the bios and we may even see an official bios with the 274 cap removed one day.

*Touch wood* this mobo is still rock solid for me, gotta love it! :D
 
as i have BIOS P1.50 with this board and my 146 opteron wont go past 274 with this bios, has anyone had any luck with OCW bios getting more from the opteron 146. Just wondering if it is worth me downloading and trying it or not. never flashed a BIOS before, dont know how or what to do etc.

My opteron is CAB2E 0545 and is currently running at 2.7ghz, but will run up to a max of 2.74 on this bios. I am on air with a Artic Freezer Pro 64, temps around 32 idle - 40*c load

Or should i shut up and be happy :)

I am running a 146 on beta 2 bios.

Been absolutely rock stable.

Running 295 at the mo, no problem.

Flashing a bios is always a little worrying and I think the beta's can only be flashed from DOS rather than windows?

However, if you follow the guide and don't do anything really stupid (or get a power cut LOL) it takes a matter of seconds and job done. :D

Worth it to me. Was "walled" at 274, now up to 295 with Artic cooler @ 1.5v (approx)

P.S. If you are bothering to flash to beta you should really do the volt mod if you already haven't or you may not get a huge gain.
 
I have not dont the volt mod, and not great soldering, and dont fancy taking the mobo out to do it, but i may do. Is your 146 the same stepping as mine though ?

Will i gain much from 2.7 to like you have 2.95 ?

No, mine is different stepping (very good stepping but can't remember what it was, LOL)

Your stepping is pretty good too I *think*, though isn't it known for wanting a little more voltage for big clocks?

Anyway.....

I would flash to beta and see what you can get out of it at 1.45v.

If you want to go further then do the Vcore mod.

It really is a doddle if you have even a clue how to solder. If not, go to Halfords and buy a Windscreen Demister Repair Kit. This is basically just conductive paint.

Apply it with a tooth pick or similar and job done. Can be removed easily too if you make a mistake or the mobo ever needs an RMA. :)
 
okay i shall try it tomorrow (the Bios flash that is) ill leave volt mod alone for time being, can you point me in the right direction for this bios, and which one i need. Also if there is a Flashing bios for virgins area as well please so i 110% understand exactly what i am doing step by step!

cheers poopscoop


PS: will i notice any difference going from 2.74 to say for eg: 2.9 ? ghz ?
 
am i right in thinking there was a bug in the bios that meant it wouldnt save vcore settings properly?

ive upgraded my bios from p1.4 to p1.6 and i seem to be able to get a somewhat higher o/c at stock volts...could this be explained by the bios upgrade allowing me to manually set multi/vcore properly?

how does a 3700+ SD running at 2.75 GHz @ stock volts with stock cooler sound? load temp reports as 50c in MBM5, with a case temp of 31 (the room is fairly warm!)

am priming now, but its gone past the point it used to fall over at already...

(Create a bootable floppy by formatting it in Windows and ticking the appropriate box to make it bootable)

Will you notice any difference?

Not in most ways to be honest.

Benchmarking and to an extent gaming will show the difference.

It's more a question of "can I live with a chip that I know I can overclock more if I want to" syndrome. ;)

Heck, I'm upset I can't get to 3gig yet, as if an extra 50mhz will be noticeable.....it's the principal! LOL :D

My opty 146 runs fine at 2.7htt with the following fsb link speeds.
CPU - NB Link Speed: 800MHz
CPU - NB Link Width: Auto
NB - SB Link Speed: 800MHz

Finding the best overclock will depend on your opteron and memory and cooling capabilities.
The key is to finding the right balance....
I found that for stock coolers 2.7 is about all it will take without temps rising too high above 55degC - above this a better cooler is needed.
Also i am running budget pc3200memory at 217 Mhz with a divider of 1/12, if i was to increase the htt to 3.0 i would have to increase my divider to stop my memory being overclocked. Also i would need to lower the link speeds above to 600MHz to compensate for the higher htt.
Conclusions...What i gain on the roundabouts i lose on the swings.......
Clocking the htt to the max may not be the solution to obtaining best overall system performance.
 
Yeah, I have my NB link at 600, width at 16 bit, NB-SB link @ 600 NB - SB Width @
16 bit though all topping out at 274 anymore and no post of course, (thats on BIOS P1.50).

I have a Artic Cooler Freezer 64Pro,

Memory clock is at 133, now i am using 3200 so shouldnt that be at 200 then ?

Damn I dont know anything about my memory or making it better. Maybe it is all working the best it can anyhow. Maybe I cannot get anymore from my machine. not to worry, works fine anyhow.

nope the 200 for memory clock isnt the actual fsb for the memory its the divider, on this mobo 200 indicates 1:1 so if u';re cpu is 274 it willbe attempting to run the memory at 274.

maybe try 166 divider.
