You're right about the NB voltage, but I haven't had to mess with the HT. I Fold@Home at 2.5GHz (239 x 10.5) and leave the HT multi @ 9x without issue. Vcore is +.15v & NB is +.10v.Quote:

Cheffy you just scared anyone that was considering watercooling from even trying it hahah. No but seriously sry you lost that card man may it RIP.
Its entirely my fault:
the block had been leaking ever so slightly from 1 barb for a while but was so little i didnt care, moving everything about yesterday losened the clip and the tiny tiny leak (so little it jsut caused a crusting of gunk arround the edge of tube) turned into a far more substantial leak, but i never leak tested while re-filling last night and just bolted it together and hit GO.
on pulling it apart to find out what caused the leak i was reminded that when i last got some new tubing for my koolance i ordered the 6mm OD pipes (as suited for the older PC2 systems) but was sent the 6mm ID stuff as suited to PC3+ and never returned it... turned out i had used some of that stuff from the gpu block
heres a lesson kids: if it leaks, find out why. if you move it about - leak test properly.
Back on subject:
I now have a board i will be replacing when pay day comes - that still works. i think i know someone with a surplus 3800+ so i can work on the ocp mod :) i think it could be done with just a pencil and DMM
Yay!!
FINALLY my 2*2gb Dominators arrived. Been waiting for them for over a month now.
They are compatible with AX78 at preconfigured values (when choosing memclk 1066MHz), memclk 1066MHz, cl5 7 7 27 or whatever they are, but... ...they wont get past dma updating screen @ 1066Mhz cl 5 5 5 15 2t 2.1v trfc195ns. Just managed to test superficially yesterday, so more testing is needed.
Got a picture of the insides of my rig before putting my new ram inside (if anyone are interested), got more pics, but only managed to upload this before imageshack fkd up yesterday:

Nice and tidy........:p:
@Jethro: Tested your X2 6000+ yet?
looks very nice mate! dont you find the elbows hurt performance??
Haven't tested without, so actually i don't know. Probably a little restrictive, but the mcp655 pump is pretty effective, so i don't think it will be a problem :)
Not bad Likmark, no elbow's here just 3/16 thick 1/2" tubing that is very resisant to kinks :). Let us know if you can get some Higher FSB's with that NB cooling man!
FYI Paypal just cleared today so no beastly cpu till next week!
I am having a lot of trouble with my 9850BE. EVerything was great with my PHenom 9500 OC'd to 2480mhz and my x2 4000+ and my x2 6000+ Oc'd to 3.35ghz, but this is a nightmare so far. I have reinstalled windows XP today 4x. I am going with just drivers and minimum programs to run these stress tests.
My PHenom even fails stress test (AOD and P95 4 threads) within 1 second a full stock speeds. I lowered my RAM down to 667mhz and the NB to 1600mhz and it fails a second. To be more specific, P95 fails 3 of 4 threads in 1 second. I just got this Abit board replaced yesterday due to a bad flash, so this is a new one. Sigh....
Specs in my sig.
Reponse to below: Hmmm...where IS my sig?! I just updated it. I am posting my specs:
Main Rig: Ph 9850BE, Thermalright Ultima90, AX78, OCZ Reaper PC26400 2 x 1GB. RAID 0 2xWD 320GB B3s, WD 750GB, Corsair HX620W, XFX GF 8800GT, XtremeMusic, Intel Pro1000 Nic.
6000+ working fine! PWM temps are now 55c Load @ 1.5v Currently at 300x11 = 3300 cant get anything higher very stable yet. Starting to think the vcore stability just sucks on this board. Both these chips just want to much juice for moderate clocks. Gonna try some better board cooling asap. Cant believe how useless this board is over 300FSB. Something isnt right yet!
Good news is with this new CPU my ram is in a more friendly range and now runs 4 4 4 12 and im breaking 10k mb's!
I'm testing a X2 4450e in the AX78, going good so far ;)
you guys think X3 would be a good match for this board, a OC'd X3?
Jethro:
im on my 2nd board now, seems very much like my last, except pwm temps are much lower despite non modded. not tried above my previous stable settings yet, but i will.
other good news, 4*1gb sticks hasnt touched stability. mem volts holding fine, timings unchanged (other than to allow the lower ability of new pair, maxed them on their own, added the old pair works fine.)
does the board allow you better cpu clock using higher multi? what sort of trouble you got in the 300mhz+ range, maybe i can try and duplicate.
sounds like you might just have bad luck, but if you can check the required volts for say, 3200, 3225, 3250 and 3275 can check to see if it seems to be scaling like my chips all have - which would indicate the cpu limit rather than board.
Gentarkin: I think an X3 is probably the best match for the board, there are (as you can see) scattered issues with the pwm and the 125w+ cpu's. the X3's (get a B3 stepping not an oem surplus B2) are all well below this level, and the board should have the muscle to push them to a good clock. added to that the low combined price for such a setup (only 780g would be nicer) and.. you get the idea.
Phenom support seems solid on the whole from the reports i have seen and the boards are well rounded in other respects also.
yeah Im wondering...if the X3 8650 can hit any decent clocks like in the 2.7-2.8ghz range at least...that would be wonderful cuz its only a 165$ chip. I am on a Opteron 165 @ 2.93ghz right now and Ive been tempted for a very long time to go to phenom but Ive just been waiting for a awesome combo of cpu and board to come along, now I gotta see if its worth to wait for 45nm and a 780a board or something....GRRRR!!!! lol I wonder if 45nm will be drop in to AX78 , if it is then I would have no issues with getting the current setup I mentioned....
WooT my new chip has unlocked this board after all! I take back my FSB whining!
327 x 10 1.45v ROCK solid :shocked:
1300HTT / 1100 Rams over 10k mb's
There is some clocking here after all!
Oh yea, the board is great if you have the CPU to go with it. Definitely won't run into an FSB problem with this Phenom, but I'm happy with it at 2.5 even if the PWM is a little toasty. :)
I'd imagine the X3's would work well with this board if they're anything like the Phenoms. Except for the gentleman having issues with his 9850, everything seems to run quite well.
Hello from Germany
I have one question. MSI removed all NB-Multi Options in their Bios Versions. I search a new Board that allow me to change the NB-Multi for Ocing my AMD Phenom 9650. I have an 11,5 Multi and need Options to reduce the NB-Multi.
best regards and thanks in advance.
Chris
Here's a review comparing X2 difference between 780G, 770 (AX78) and 790FX http://www.cpu3d.com/index.php?optio...mid=54&limit=1
I need an answer pls ;)
I do not have cpu-nb fid options in either bios 12 or in beta bios 13a. Appareantly there is supposed to be cpu-nb fid in beta bios 13a.....
damn, also you expect that the Beta Bios 13a include maybe the cpu-nb fid?
Redid my radiator shroud yesterday and moved a fan Directly over the PWM. Stability as went up tremendously as a result! CPU load temps on the highest temp core are 43c @ 1.5v. (33c ambient)
Can bench up to 338 x 10 now! Board craps out > 340 so far. After folding all night PWM temps before fan were 58c now with fan its around 50c.
What i found in my case is that if the PWM hits 60c or more the board shuts down!
This board is really fast @ 330+ i must say. Breaking 11k 06' untweaked, 130k+ Aquamark, 10500mb's / 39.2latency and 25sec super pi.
I am currently using the beta bios, there is no cpu-nb fid in it. SorryQuote:

so that the NB stays at a lower clock? translating to higher core OC potential?
Yes in theory. It should not be a problem at all as you can give NB lots of juice with this board anyways. You probably won't be able to overclock the cores that much that it becomes an issue in the first place.:yepp:Quote:

I can change the NB multi on mine. From the manual:
andQuote:
CPU-NB FID
This item (appears only with AM2+ CPU) selects the processor to north-bridge frequency.
http://www.myalbumbank.com/albums/us...80/NBmulti.jpg
:)
Strange, It must be cpu limited for me then. I have tested changing it with BAR EDIT too, and it dosen't work either. @hoki: you're running beta bios 13a too? (That pic from the manual was one of the reasons I bought the board)
I'm in Ubuntu 8.04 right now using AX78 with 9850, for over 3 hours now, benchmarking mainly.
I'm using stock BIOS and it booted and runs perfectly. I'm using my MSI board settings, 2700MHz stock voltage, 1.288v, just placed a heatsink on it but its not attached and there's only old TIM :p: The PWM are running quite cool, cooler than MSI board and far cooler than DFI M2R. Only got 1 stick in yet, busy online yet.
http://imageupload.com/out.php/i111441_Screenshot1.png
http://imageupload.com/out.php/i111440_Screenshot.png
The 43/44C is BIOS reported temp.
Board fails POST with C1 using 1066/1000 RAM modules but works perfect with 800 RAM modules. It also boots very weird timings but has CPU-NB voltage control although there is no NB-FID option in this BIOS and I do have it on other boards.
In XP now;
http://img146.imageshack.us/img146/4900/ssep2.th.png http://img206.imageshack.us/img206/7087/wpxv7.th.png http://img525.imageshack.us/img525/2989/wpfla9.th.png
Next I'm going to shoot for higher, 3000MHz -- easily with the CPU's range but let's see if the "idling instability" exists on this board too.
Volts is reported accurately so far..
3 in a row for me... :D
2.8GHz 9850BE stock voltage = 1.292/1.288v ID / 1.280 LD
http://img233.imageshack.us/img233/8420/2800nv8.th.png
These aren't just ss, I'm benching them trying to invoke an error - previously MSI and two GBT boards have found the core is 3055MHz 1.355v stable, so this is well within the load range.
Only trying to check if it suffers what they suffer -> idle instability.
All other boards failed at the above setting, freezing idling at anything above 2700 at any voltage... so far Abit has not froze or given any hiccups at this setting and its also the first BIOS.
Issues
-1066 RAM just does not run with this board - C1. :(
-How do I get unganged mode, there's no option as such anywhere?
-Also I cannot get my 800 RAM to run 1066 mode with Phenom in there (it can do it easily on other boards).
-Abit EQ keeps starting yet is not in autostart and keeps harping on about running as admin first time even when I've done it ten times and it still won't come on :shakes:
The BIOS voltages work perfect for me.
0.1v NB adds 0.1v to NB.
0.02v CPU adds 0.02v to CPU, all the way up, I tried it.
Thanks for sharing. :) I'm looking for an affordable 9850-able mobo (I don't need multi gc). Probably will go for this or gigabyte 780 :PQuote:

There wasn't a fan in the above shots, no. But since then I added one around the back, I always do it to rule out factors when testing as a good assurance. Fan is more around the back of the heatsink than the PWM area though.

Ambient is quite high, around 25-6°C and the "CPU" temp is taken from BIOS/Abit EQ gathered through ACPI. The "core" temp is taken from K10 sensors, its the same as 780G/790FX report.
BIOS 12 doesn't give me NB FID, going to try 13 B2 now. LIke I said earlier, MB is very good and excellent for the price, but it can't be in wreckless hands.
tell me pls if Bios 13B2 include the NB Fid.
I saw on the Bios Screenshots, that there is an NB Fid, cant you change him or whats the problem?
Chris, I am using that BIOS, I have flashed them all one by one - there is no such option in the BIOS unfortunately :(
I've tried boards where there was and they changed it fine - this one doesn't have it. However, I'm just going to use Bar_Edit to change it temporarily for testing.
This board does not run 1066 mode or 1066 mode RAM (2 kits) at all! One big peeve of mine, it does give plenty of options though but no POST if you try 1066 with 1200-1380 capable RAM. The chip runs it fine though.
This board has no option for Unganged mode anywhere! :(
Also I ran EVEREST comparisons across both boards.. AX78 at high/loose timings and 800 clocks performs better in MEM than the MSI 790FX with tight timings in 1066 mode ;)
Ganged that is.
AMD OverDrive runs the quickest and smoothest I've yet seen to date on any board, wow. MSI is 2nd after this board but it really is no where near this good :)
Also, in AOD, CPU VDDC is a dead value.
Next up to try is Auto Clock...
OK now for the bad news :)
This board is just not made for high volt/watt CPUs. I would say stick to stock volts, simple as that.
I am 2750 stock volts stable... but I fed the CPU 1.4v 2.5GHz and the system shut off instantly - nothing but motherboard.
Then rebooted and it would not boot for a while - the board itself won't start.
Then tried 2.7GHz stock volts boot, shut down at Windows loadup as soon as the power draw topped 100W on CPU.
Then tried stock boot, booted up.
Now at 2.7G/2.8G/2.7G/2.7G using AOD at stock volts but I booted up 2.5GHz on all.
There is no;
overheating
rail tripping/faulty-weak component
anywhere - this is totally the motherboard not able to withstand high power draw by CPU. The shut off is instant, as if you tripped a power rail or overheated too much. But the fact is, none of those are happening. The tems are 30-40C maximum and the rails have 300W still spare working fine.
I fed CPU 1.5v in AOD and the system shut down there and then! Again motherboard, not my CPU because on other boards I can bench <1.6v on Phenom perfectly fine.
So with a 1.3v chip, I'm stuck to 1.3v on this board -> hold your horses though, I'm still experimenting :yepp:
@KTE: 1066 memclk mode runs, but with horribly loose timings (6 7 7 20 etc..). I have made choosing unganged mode once, and it involved multiple auto settings, so I have not been able to reproduce it. :(
Were you able to change cpu-nb fid with BAR EDIT?
This board would surely be more xtreme material if not for the very weak power handling. I had to ditch 330+ fsb, everything was wonderful till NWN2 and she just refused to be nice. Even at current she still flakes out now and again. All voltages reduced to minimum and everthing well within spec and she still act's up now and again. Might keep it for now but its not gonna be my phenom board I'm quite sure.
Current 98% stable settings = 300 x 11 1200HTT 943ddr 4 4 4 12 2t 1.5v cpu... 1.31v nb 2.00v pcie 1.3v HTT
Ignore post#237 by me. ;)
I've figured it out -> it's the friggin BIOS not the board, 13B2 is very buggy!
It gets stuck at bootup with 2F/2B code, then keeps recycling it really quickly.
It also takes around 25 seconds to reach C1, just before system starts.
It will not startup many times getting stuck at the above codes at stock.
It will not allow voltage adding to CPU, it'll reboot before startup if you do.
It will not boot anything but stock.
BUT, thanks to MSR Editor and Sam's MSR Tool, I've been running/benching 2700/2800/2700/2800 across all my cores stock voltage since my last post here without fail (no idle freezing, which is what I'm trying to avoid)
Look here, 26C ambients: http://www.xtremesystems.org/forums/...5&postcount=80
I have even ran 2800/2900/2800/2800 stock voltage running the old and latest two x264 benchmarks for about 20 minutes full load, no problemo including the PWM being 45C max, which is excellent (now have a low speed fan over it) for any PWM as they're rated for 110-120C.
So it is not a PWM problem but a BIOS one - I'm reverting to BIOS 12 now unless someone has one after BIOS 12 but before 13B2?
This is what I'm testing for 19 hours now, going very strong.
http://picsorban.com/upload/27-28-27-28.thumb.png
Still sticking to stock voltage, I know I have at least two good cores which'll do 2900MHz stock voltage.
Just a note: Phenom cores are arranged like this by AMD and this is how they're picked up by AMD Power Monitor/CPUZ;
core 0 - core 1
|.................|
core 3 - core 2
So anything you use which thinks;
core 0 - core 1
|.................|
core 2 - core 3
will get it wrong (i.e. MSR Editor).
Thanks for the help :)Quote:

You are running XP 32bit I presume. Under Xp 32 bit this bios was VERY buggy for me too, under Vista x64 there is "NO" problems (exept for general unwillingness to give good tight ram timings, and no logic (at least for me) ganged/unganged mode settings). When playing with ram timings I've got som serious no boot issues though, that can only be solved by taking out the cmos battery for a long time.Quote:

Then it definitley is cpu limited for me. Very strange that some cpu's are limited like this. (it is a week 44 though, pretty early batch, that might be the reason?)Quote:
Anyways.. just bought myself a L164WS/B and a barcy, looking for som fun :) Just need to wait for it to be sent from the US :)
Yes, I'm running XP 32b and Ubuntu 8.04 32b with that.
I also had all those weird RAM timing issues, no boots so many times. :confused:
Is there any BIOS after 12 but before 13B2 you have?
My week 44 9600 was also CPU limited, could not downclock the NB on any board or BIOS while the others could (non BE).
Week 43 and 45 9500/9600/9600BE were all fine.
Good luck with the Barcy.. which one BTW? :shrug:
It is the achilles heel of this board IMO, If they could fix some decent ram values I think it would shine as the best entry level Phenom board.Quote:

It's a 2347, 1.9GHz with too low cpu fid for real fun, but they're the only ones that is possible to get hold of at a reasonable price. Seller stated it was a B3, but I think they only comes in B2 flavour. Overclocking probably will be limited by cores before cpu fid anyways. (always hoping for the opposite to happen, though:))Quote:

Bar_Edit is a tool to change the NB-Fid?
Then you would say, that this Board is better to oc as the MSI? MH 4 Phases vs 5.
Yes we change NB FID using Bar_Edit or WPCREDIT for a long while now ;)
We change CPU FID, CPU VID and NB VID using MSR Editor/Sams MSR Tool aswell.
You can do it on any AM2+ supporting board, the registers we change are within the CPU.
Abit board is 770, MSI board is 790FX.
Both are very different categories, different price, different offerings.
Abit 770 is tons better than the MSI 770/790X no doubt.
MSI 790FX v1 has far less problems with Phenoms, much better support/compatibility but also less BIOS options for oc unless you go to 1.13b, which is one of the best performing/overclocking BIOSes I've seen. It has everything you need.
They are different boards, I would wait for a good BIOS for Abit board if you're planning to get that with Phenom B3, but for less than the price of GBT 780G, it's one excellent price:perf board!
-MSI board is the best 790FX offering in terms of price:perf at the moment, without a doubt in my mind. Best RAM clocker aswell. But I would not use it for over 1.50v load 125W CPU clocking, go DFI/ASUS 790FX for that.
-Best high end clocking, over 1.5v is DFI/Sapphire and ASUS 790FX, but all three are too expensive for what they're worth, not worth their price and only better if you go over 1.5v because of the PWM and because of better oc BIOS options.
-ASUS 790FX is far more stable than the DFI, DFI just has too many issues and weirdness, like always.
-Abit, IMHO, is the best 770 I've come across so far including the ASUS M3A coming second - they just have to resolve some major BIOS issues: RAM/NB FID. I would also limit the voltage to sub-1.4v with 125W quads personally.
-ASRock 780G is better than GBT 780G aswell, just to add and GBT 740G is not good, to say the least.
I have hit 224HT with AX78 fine so far, all stock voltages: http://valid.x86-secret.com/show_oc.php?id=355810
Haven't tried more because of bad BIOS.
Where the heck is cutie nowadays by the way?
Did he go crazy for that girl in his av or something?
***I know you're reading mate*** :p:
Ok, I see several of you have memory timing / OC'ing issues. This was an answer to KTE's post in the abit support section. It may (hopefully) clear up some issues you are seeing:
Secondly, regarding your multipliers, are you all disabling Cool n' Quiet? If not, the option will not be present. You have to disable CnQ to be able to change your multiplier.Quote:
Most likely the reason you can't OC your memory is the tRFC timing. That timing on this board is measured in ns and are selectable individually for all four DIMMs. By default, the empty slots are set to 75ns. Unfortunately, for whatever reason, it'll change one populated slot to the setting it should be at (either 105ns or 127.5ns, depending on your memory) but it treats all three other DIMMs as empty with respect to that timing. Anyway, long story short, change the DIMMs that you have memory in to 105ns and try again. You can probably clock your memory higher at that point. If not, try changing both of them to 127.5ns.
Perfect timing. I just ran all my tests :)
My post to Abit is here: http://www.xtremesystems.org/forums/...d.php?t=186671
First of all, yes you are spot on. I checked about 45 mins back and was intending to post on it; the issue of no POST and weridness is on all BIOSes and it is caused when you move tRFC from 127ns to 105ns or lower. Sometimes USB keyboard stops working and graphics screw up this way. If you change it back to 127ns, it all works fine.Quote:
Originally Posted by hokiealumnus

The rest of the RAM issues are timing independent. I've tried the highest there is, no 1066, no unganged.

I'd need a list of detected chips from the SMBus interface. I explained it as far as i could over at the Unified DFI thread.
I wonder if the freezing might also occure if one of those better clockers run with a too high voltage for them.

Hmm.. I've already done this test quite a while ago. With mine what caused freezing at stock volts also caused it at 1.55v - if it was idle instable, its always idle instable no matter what you do :shakes:Quote:
I wonder if the freezing might also occure if one of those better clockers run with a too high voltage for them.
For me, its just some weaker cores, I mean, you can see my above results and compare that I was stuck at 2700MHz before max :D
BTW, AMD advisory lately released a public report about the consumers wrongly choosing low end, budget and mainstream motherboard designs for high performance processors, which they said is completely asking for trouble as they weren't designed for it. Since then a lot of major distributors/retailers are placing a cautionary advisory under the motherboard specs. Just FYI:
EDIT: As I said right at the start, with appropriate cooling, many will have no problemo. They need to do a lot more before trying to hurl out half-done articles causing mayhem and those without knowledge to just follow.Quote:
The vast majority of the 780G boards have a three-phase or four-phase PWM circuitry design. These designs are completely acceptable for the 45W, 65W, 89W, and 95W TDP rated processors; however, drop in a 125W TDP processor such as the Phenom 9850e or 6400+ X2 and you are asking for trouble
AT updated their initial blogs: http://www.anandtech.com/mb/showdoc.aspx?i=3299&p=1 [I've snipped]
The ABit AX78 would definitely be fine if those are, it has much better PWM area and the heatsink if installed properly - I idle 31°C PWM and 27°C surface heatsink temp with stock volts 3000/3000/2700/2800 MHz 9850BE, 25°C ambient - sub 43°C under load ;)Quote:
It is time to introduce the fine print and disclaimers when using these boards with a Phenom 9850BE. As a recap, the critical aspect of running a 9850BE at stock speeds on current 780G products centers on the cooling of the PWM circuitry. Each and every manufacturer along with AMD agreed that cooling the MOSFETS properly was critical to the successful operation of the board at stock or overclocked speeds with the 9850BE - and to some degree, the 6400+ X2. This is based on the board manufacturer utilizing a properly developed power delivery system that is designed to handle the 125W TDP processors and in the future, the upcoming 140W TDP Phenoms.
Everyone probably knows the old saying about the three rules of real estate, location – location – location. It holds true with our board samples only replace location with airflow. We found additional airflow around the PWM/MOSFET area was critical when utilizing the stock retail fan/heatsink in our Silverstone SG03 case. We installed a secondary 120mm fan that provided enough airflow over the board to ensure stable operation under our load scenarios. While that was acceptable for the most part, it did increase noise levels a little more than we expected. In the end, we ended up replacing the stock case fan with one that offered slightly higher airflow with only a small penalty in acoustic levels.
Utilizing our standard test bed components with the 9850BE, we ran our Jetway, ASRock, and Gigabyte boards over 102 hours each with a combination of OCCT, Microsoft Flight Simulator X, and PCMark Vantage benchmark loops. We did this with the case fan modification first and then again with the Thermaltake RubyOrb installed. We did not have any thermal related failures or shutdowns under load as we had experienced with just the retail heatsink installed in previous testing. We also overclocked the 9850BE slightly to 2.7GHz and ran an additional 48-hour combination of OCCT and PCMark Vantage loops without a problem utilizing the two front-mounted case fans and retail heatsink.
Our Biostar and Sapphire boards both passed the 102-hour test. We did experience thermal related shutdowns with OCCT around the 40-minute mark on both boards with just the retail heatsink and standard case configuration. This also occurred around the two-hour mark with PCMark Vantage. In fact, we had Biostar send us another board after a bad overclocking experience (our fault for trying) with the 9850BE on an open test bed setup. We did not test either board in an overclocked condition but feel safe in their capabilities to run the 9850BE at stock settings with proper cooling.
as i mentioned earlier - the shutdown under load with higher clocks/volts is the ocp protection on the pwm controler.
i have a pretty good idea how to up the limit but lack the tools to do it. we need to alter the values of 4 surface mount resistors and pencil jsut sint going to cut it as we need the final resistances to be as near as possible exactly the same.
OFC we need to be aware of the warning given above, but i have quiet confidence given that the 4 phase system on my old abit AX8 survived 3200mhz/1.75V on my old X2 without any heatsinking and we used to have many a board running 2 phase on 70w thunderbirds - so it should be technically possible.
ill dig up the spec sheets for the FETS if anyone is interested.
also, fyi, the PWM temp is read from a thermistor positioned right next to the FETS where you would expect to see the LPT port usually, tiny black surface mount component sitting just out from under the heatsink in a big island on the pcb. (i traced it back to the winbond monitor chip in the bottom right corner, close to the C1 led.)
That would be the case if someone else can run 1.45v load 2.6GHz on a 95W CPU and make it shut down. Unfortunately, some people are running 95W 9500s at those settings, even folding daily without any shutdown, which is roughly 150W draw, so what exactly is the OCP limited to and how to find out?Quote:

I wonder if "i2cdump 0" also shows a chip at 0x2e, whom is responsible for the freezing.
What version of lm-sensors comes with etch? I use lenny so i had the latest stable 3.0.1 version here.
Thanks, that is from the SB600 docs i guess?Quote:

My last 9850BE also had a bad third core and the fourth also was no good clocker. Cores one and two ran 3GHz at ~1.325V.
New update - core0 3000 stable stock volts, but core1 will fail, max is 2900 at stock HT - so bump in voltage, now added 0.05v, at 1.344v idle/1.338v load at 3000/3000/2700/2800 testing for another 24 hours or so. No fail yet, just ran 2 benches and EVEREST stability test 30 mins. +1 hr gone now...

Yeah, I know what it does but like I said it never worked. Installed latest lm-sensors manually (2.10.1) and then ran i2cdetect 0, never gave any feedback, failed and then second time froze my system. Rebooted and then ran it again, no output. Then ran i2cdetect -l and it again froze my system. No idea if its broken but none of these commands nor sensors-detect does anything odd in Ubuntu, I had tried it once before a few days back.Quote:

I'm perfectly fine with it since AMD themslves demo'd and allowed us to clock cores individually in their own public software: AOD.Quote:

If it was problematic, they wouldn't do that. Anything causing them headaches, they always remove, even if its something rare.
Looks like mine and yours are similar. Mine is on 3000 1.344v/1.338v idle/load stable now for about an hour. Load, it can do 3055 on all cores at that voltage stable, but idling I'm still testing :shrug:Quote:

You need SB700 support in i2c-piix4 to dump the i2c/smbus devices.
Thanks, I got my hands on the spec of the clock chip they used on the M3A and the Sapphire board, the GBT uses an very similar chip. I also have the specs of the clock chip used on the M2A-VM. So i'll try to write a small kernel module to read out ref HT and pci express clocks. It might be extended to change those frequencies in the future. Depends on how much time it will take. :rolleyes:Quote:

I think I've reached a limit whereafter voltage won't make a difference. I only want to add upto 1.45v real max, no more but I don't think I can get more out of core1/2/3. Core0 may do 3.1G, I know it'll bench/load test it but it may not be idle stable after 1-2 hours.
Ah ok, thanks. The version I downloaded said it was the latest but the version number was exactly what I posted. Nevermind :shrug:Quote:

Agreed, it could be. That's a good point, I'll have to think that over - how to eliminate. Maybe testing by disabling one core at a time would be ok?Quote:

I'm not sure but, if you disable a core in Windows but reboot setting say 3000 across all cores in BIOS -- does the 4th core get set to 3000 aswell or do they keep it at stock on boot? :confused:
I got into Ubuntu, ran it and got all I/O details fine. Was posting them to you but the system froze (3000/3000/3000/3000 1.355v). So have to go back into now and will post.
Currently I play with the clockchip of the 690G.Quote:

I'm still very busy at work till june. Have two weeks holiday then and will work on that module then. Meanwhile i'll do some theory (reading other sensor chip module code and stuff at smbus.org).
I guess windows does not use the downcore method for unused codes so it will run at 3GHz but do nothing (beside freezing maybe).Quote:

A good test case should be:
1. Disable all cores beside core0 and find the higest voltage and frequency the core can handle. Use the higest voltage as the top limit in 2.
2. Add cores1-3 individual and find the highest voltage and frequency for that core.
3. Use the minimum of the max voltages of all four cores and find the max frequency for each core at this voltage.
4. Enjoy your overclocked system :)

Also KTE, the results you're getting now, did you get any of these results on any of your other boards like MSI, GB or what else you have? Because it's a little unclear atm for me as you post in all the threads for specific boards telling you get x results and I dont understand anymore if that's only with the Abit or if you got it on other boards as well:p:.
My 4th core (in AOD Core 3) was able to run 5 minutes 2.9Ghz stock Volts. But But AOD is too buggy for me to actually continue testing. If you put all the core multi's at once system might freeze and for some reason some values give me 'Machine Check Exception' BSOD. Well, Im done with it.
Either enable Crossifre on 780a boards, which wont happen most likely, or get SB750 FAST.
First i want to track down what killed my chip. Second with a module for the clock generator it would be possible to change the ref HT in realtime.Quote:

Awesome, thx a lot.
Hopefully it will give better results. I think VID options in AOD were bugged too. CPU-Z read 1.232Vcore while AOD set 1.3V as set in BIOS. But without opening AOD CPU-Z read 1.29V which it always did.
Really considering another brand motherboard though when SB750 is out. The noises coming from this board and other issues make me concerned that it might at some point put its finger up in my face and kill everything.
Nice. Why is that showing maximum PLL oc at 280MHz?Quote:

According to that data, only HT to 280MHz is defined for the SB600 PLLs with X2s. They don't have data for K10 in there, the new docs are supposed to have released now though.Quote:

Yep. Probably not because my BIOS doesn't use SVID interface but the DFI/Sapphire does.Quote:

If so, then yup that's true. :)
Hmm but i ran an X23800 at 3GHz on this mobo. That is only possible with an 300MHz ref HT. I think bytes 11 and 12 play the main role for the ref HT.Quote:

I can verify, no issues at all with lm-sensors on Ubuntu. sensors-detect is the command I used after installing. It did require a restart though. I'm actually using sensors-applet on my panel 24/7 while folding. Works nicely. Oh...and this is 8.04 x86-64 (duh...can't fold with 32-bit :) )
Thanks for the info.Quote:

Good to know this board works well with Ubuntu! Thanks for the info's. It shall become my moderately overclocked office box as soon as the new south bridge mobo's hit the streets :) Cant believe that I'll have to spend $160+ to get a truly xtreme mobo!!! :eek:
Thanks for that, nifty. Have to try it now. ;)
Those wanting to buy Phenom 9750/9850 with this board -> here's the problems it has, I've wrote them here so you can decide: http://www.xtremesystems.org/forums/...5&postcount=13
I could not get 3100/3000/2700/2800 stable.
Still running 3000/2900/2700/2800 stable, stock volts.
Thats a nice summary KTE. I'm taking a break from the AX78 now , installing my Crosshair again now that there is a new bios I need to test :)
What about the Barcy? :(
BTW, 3000/3000/2700/2800 1.384v stable since my last post :D
It should be under way togehter with the L1N64WS/B unless I'm being ripped off. I sure hope not. BTW It is a BA stepping so I don't have too high hopes of overclocking it.
Oh ok.
Update is, ignore my last post results.
Latest stable is 3000/3000/2800/2800 1.35v ;)
Anything higher on volts will shutdown system within ~5-1200 minutes
Will you be able to auto clock that settings upon logging on? I tested some "apply upon log on" settings with AOD with little luck. You tested that?
I haven't tested it yet TBH but I use Sams MSR tool to change to the required VID and 2800 across all cores on boot, auto.Quote:

1.352v suddenly switched off idling at 2900/2900/2700/2800 after mre than 30 hours. A PWM thing, cut power at once. :(
Cool, so you found the upper limit. Does it always shutdown or also freeze or fail prime?Quote:

No load failing or idle failing - its a different problem. PSU cuts power to system at once usually under no load. I think SnM test L2 Cache can replicate it, I'm testing it now.
Tried stock MHz/stock volts, 26°C ambients, low fanspeeds, 221W AC
Attachment 78219
Next up is 1.328v just to see if it can hack it.
I've got little time, quickly adding what I can.
I tested and the limit for the MB PWM causing that shutoff is 1.328v - with 9850BE nothing at that or higher will be stable on this board, S&M will fail during L2 Cache testing.
LIKMARK please keep in mind what I just added.
For x2 owners 1.45v seems to be about max 24/7 for a QUIET setup. My PC is virtually silent. Thats with modded sinks and letting faneq do its thing mind you. YMMV
Current settings 3.22 @ 1.4v (might go lower v yet) Ram = 1076 cas 4 2.2v!! This board pushes ramz REALLY nicely. Back running beta bios, AOD didnt work with official bios 12 for me??. Have extra chip on hand, had to hot flash once already. :) Extra chip cost $13.80 after shipping US monies.
I was a little disappointed with the board pwm wise but in reality she is a stellar board overall if you can live with lower volts to your cpu. In a day and age of trying to live greener it is probably for the best.
Please forgive me for asking this question as I did real the entire thread twice but I saw a few conflicting answers. Does this board indeed post with the shipping BIOS when using a Phenom 9850BE and 2X2GB PC2-6400 ram? I believe you guys say it will, I just would love a verification. I rushed out and bought this damn ASUS board without thinking or logic when I got my Phenom and I need a good $100 board. Thanks in advance!
Todays AX78's are shipped with BIOS 12, 9850BE is not on the support list, but forum user KTE is using 9850BE with this board. I myself have been using ballistix with this board, although mem compatability is not one of this boards strong aspects. KTE is experiencing difficulties when feeding above a certain amount of voltage to the cpu as the PWMs closes down because of "out of spec" load. I think he can run it at about 1,4vcore before shut down.Quote:

the general feeling is bios 12 will post with the 9850be fine, and it should run stock fine also. the board is much more picky with phenom/ram than x2/ram however, it apears to be a sotrming board forr am with x2's and meerly ok for phenom.
when it comes to overclocking 125w cpu's then your going to be limited in the volts you can manage - with the 6400+be about 1.475 to 1.5v is the limit. for the phenom about 1.35v to 1.4v
Thanks for the info guys! At this point, it could not be any worse than my current board which is pretty much guaranteed to explode if I try to overclock it. I have such a limited budge that my choice is limited to the 770 based boards and this one seems to be the strongest. Any other info if greatly appreciated!!!
There is at least one person @ the abit forums running a 9850BE + AX78 and it worked with the shipping BIOS. Like LINMARK said, KTE is running one as well. I have v.13beta02 (available here) running and have no problems. When you start overclocking, you're definitely going to want to cool that PWM off, they run quite warm once you put some Vcore to these Phenoms, especially that 125W one.
If it will post with the shipping bios then my life would be complete if for just a short time. I don't have another CPU to flash with and spending $115 (after shipping) is even slightly over what I can scrape up to buy it so it will be a brick if it cannot post with the shipping bios. Thanks again!
Over current mod,
not varified and theory only.
resistor marked 59c, to the very top of board, in the middle of a bank of 5. middle of the ISL6232 chip then head up puts you about correct.
The resistance should be about 40K (its a 40K2 resistor) try nudging this down a little and you should see the v-core drop and the max current drop also (eg now gets even worse) - if someone brave can confirm this with pencil mod then thats the simpleish fix - replace this resistor with trimpots letting you nudge this value up and down from here. pushing resistance UP should raise v-core and OCP limit. down reducing both.
At your own risk!
Not Varified!
Calculated from Pages taken from datasheet for the IC and from much digging about with a cheap multimeter and 5 year old A-level electronics. so dont hurt me if im wrong
hi guys,
i have a question or rather a request. can some please post pictures of what options are available when you enter the PCIEXP1 and PCIEXP2?
what i mean is is there an option to bring down the multiplier to 4x for both slots?
i would really appreciate some screen shots for both.
And has anyone used this mobo in crossfire mode?
link to image of what i mean

Thanks

Hello,
just wanted to buy the board to overclock with an AMD 4850e
Is there anybody who got some experiences? Does it work, does the Board recognize the 4x50e models?
And does the GSkill F2-8000CL5D-4GBPQ Kit work with the board?
Would be nice if anybody has some thoughts on this.
Abit forums have a thread about compatibility for ram/hsf for this board, it is linked to earlier in this thread. I think the ram you mention work with the board. Check out abit homepage for cpu support. The board works without issues for all processors exept 125W cpus, where some users have had issues. That should not be a problem with your 45W cpu..
The linkage you referenced (plus a couple more to some crap I threw together):
- RAM / HSF Compatibility Info.
- How To Build Thread. (Geared toward newer builders; skip the text and look @ the pics.)
- Heatpipe Mod Thread.
(56k warning on the last two, lots of pics...does anyone at Xtreme Systems even have 56k? ;) )
so i just received the board now and everything works fine, especially the overclocking but there is one big problem:
The Network connection is so slow that every page just need hours to open and downloading is impossible, don't know whats going on...
I'm using Windows XP x64 and the latest Marvell Yukon Drivers from their website and i also tried it with the drivers from the packaged cd but there is no chance...
Rest of my HW:
Abit AX78 Bios 12
4GB Gskill - DDR1000
AMD 4850e @ 3,0Ghz (261x11,5)
X1950 Pro
X-Fi
Hitachi HDD
Antec Earth Watts 380
does anybody has an idea, because i need internet on my main pc,
this is soo strange :/
That is rather strange; haven't heard of that before. Just to be sure; it's operating, but not fast, right? Try uninstalling it from device manager and letting Windows auto-detect it. This is a fresh install of Windows, right? You might want to restart your router as well just for giggles.
yeah it works :)
i switched the ports of my two pcs at my network sockets on the wall and then it works but the other pc got the same issues so i made a direct connect to the router and now everything is fine.
Don't know why one of the sockets is broken, but this is very confusing. Because it worked before i changed the motherboard... :/
