ABit AX78 Overclocking/Stability

[doompc]

I will let you all know on the weekend. just got my board and my CPu should be here in the next few days 9850BE, i already have 2 x 4850,s so i shall keep you posted.

Looking forward for the Crossfire tests
I'll try to get the secound 4850 to compare

[SmaKKed]

Well no CPU today ed Australia post they dont even know where it is. SO i have to wait till next week
Im stuck on my Trusty k650 AMD 512 meg of ram for now. lol

[Jethro]

I'm getting a 9950 next week DOH! Anyone think thats a bad idea with this board? Been awhile since ive smelled burning mosfets!

I'm getting a 9950 next week DOH! Anyone think thats a bad idea with this board? Been awhile since ive smelled burning mosfets!

since the board is already officially supports 9950, i assume it's safe to pair the chip with. but for sure the overclock will be bottleneked by the board.

Anyone running Crossfire on these boards? If so what kind of results are you getting?

i'm cross-firing a pair of 3850 on it, but so far i'm more concern bout my phenom oc. once i'm settled down with the cpu oc, i'll start the graphic oc. it's useless to test the how well is the graphic if ones don't have a good cpu (overclocked).

[SmaKKed]

Well im up and going with a 5000+ Cpu for now but one of my 4850 is dead no power i get no lights at all , tried it on a heap of other systems and no go, so we wait a little longer for X fire. But this board is pretty nice for the price $80 Australian. im impressed....Oh and its good to be back on AMD aswell

Picked up a 9600 to play around with instead, couldnt resist gettin one for around 100buxafter instant rebate and ram combo(girlfriends puter). Cheap enough that i can push it really hard and not cry if i fry it woot I plan to throw the volts at it since my cooling is pretty stout! If i can hit 2.7 or so id be stoked! That would be around 40% more crunching power not including the improved IPC etc over my current 6000+. I'll explore the boards phenom clocking potential fully and post my findings.

You should be able to. I can get 2.610GHz out of my 9500. Haven't had time to try pushing much further than that. What I have tried didn't work (pure Vcore increase). I'm not giving up, just putting it on hiatus. Looking forward to seeing what yours gets!

Ok so ive just gone back to amd.

Abit AX78
5000+ @ 3100Mhz
4 Gig OCZ Ram
Ati 4850

On this system i run the Crysis Benchmark CPU bench Island
Card is OC to 700/100

And i get

Its not much but AMD is faster, i wasnt expecting that i was expecting a decrease
All settings in crysis on high and both done on vista 64bit buisness

[Pillo-kun]

faster? look at the minimum fps, thats the important numbers, but im impressed how well amd perform.

[SmaKKed]

Yeah i know the lower FPS is slower but average is faster??

On this board can anyone get there GPU to run in PCIE 2.0 ?
Ive tried all sorts of combos and it wont kick in

[Jethro]

9600 black edition arrives tomorrow WOOT. Will post some prelim results tomorrow night. Shouldnt be much trouble to find the initial frequency ceiling being an black edition. Its not a 9950 but maxing out an unlocked 2.3 will be more rewarding anyway W/O reading back thru this entire thread does anyone know offhand what kind of HTT i should might shoot for with this board?

Off topic : Hokie arent you from Raleigh NC?

your in luck kiddo

i was up against the same problem for months but i finaly worked it out, with about a 95% success rate,

original post: http://forum.uabit.com/showpost.php?...58&postcount=1



ok guys i truly think i have worked this out, i may be wrong but i have tested this now with around 20 - 30 reboots and starts, and this rig is loading and takes ages to fully reboot, so hasnt been a joy, to say the least, anyways heres my findings, and solution.

i may have a couple of directions to certain parts of bios wrong (doing it from memory), but will edit the post, if any are found to be in the wrong place.

ok, start computer (cold boot) and go into bios (press delete)

once there got to: Advanced Chipset settings> PCIe config

(assuming you have your card in the top slot)

in there got to each slots settings,

the first one: (PCIe x1 leave alone,this is used for your marvel ukon Ethernet chip)

Second one PCIeX16 (your cards slot) hit enter, and you will have some options, go into 'high Speed gen 2 mode' and and change it from 'disabled' to 'auto' and also change the transfer rate from auto to x16

third one PCIeX16: same as above but only change the 'high speed gen2 mode' from 'disabled' to 'auto' (this is the only option you will have in an empty slot)

fourth one: is there a forth one? anyways leave it, its not important

save the settings (F10 + exit) and the machine will reboot.

here comes the magic bit

when you enter windows check the 'status' of PCIe v1.0 or v2.0, with GPU-Z, it should say that it is set to PCIe 16 @ 16, ok, where is my v2.0?

now shut down computer, and leave to simmer for 20 minutes at gas mark 3 (sry wrong thread )

yeah shut it down, no restart !!!! and leave a few seconds, then hit your pwer button and boot into windows, have a look at GPU-Z and you should have PCIe v2.0 X16@PCIe v2.0 X16.

i think it must have been with the 'switching' between 2 standards that required the power down before the switch itself, i dunno. but it works for me

can you guys that are having this problem confirm the 'solution'?

we will see,

well i have rebooted a few times now and look , http://www.techpowerup.com/gpuz/mxxnv/ wahey !!!!

and slot 2 on the ax78 is resigned to x4 when in crossfire, but at PCIe v2.0 you can double that, so its really running @ x8 v1.0, seems crossfire might be a viable option here

[informal]

faster? look at the minimum fps, thats the important numbers, but im impressed how well amd perform.

I wouldn't put much weight into those min. fps stats since it can be a number of reasons why one system goes that low(ie. swap file access).Both systems seem to dip in the "teens",at 2 different locations.

I think mine topped out somewhere between 245-250 range dropping the HT multi down to 8x and giving the CPU NB Ref Voltage +.10. I'm not positive though and don't really recall because it's been a while since I've had time to play with this build. It's just what my scattered brain seems to think it remembers.

Off topic : Hokie arent you from Raleigh NC?

Yep, sure am! Are you as well?

[Jethro]

Ty for the infos Hokie, good range to start in! Yes i am from Raleigh! I have a woodshop downtown I build fine furniture and soon some really nice PC cases via my CNC! We should hook up and geek out sometime!

That'd be a blast! PM me some time. I'm very busy right now, but sounds like a great idea to me.

[ah_khoo]

for those who is interested to know cross-fire result on this board



test was ran on:

1. vista ultimate (32-bit)
2. cards on stock speed
3. overcloked cpu & ram

[Cheffy]

looks pretty good. single card is arround 10K im guessing? 14K looks to be about mid-high field score, going by the ocuk leaderboard for this sort of setup

im just trying to find courage to put my "burned" 3870 in pins 3&4 got shorted and burned in a water leak. ive cleaned that up and theres no apparent shorting now (dmm) but i dont wanna kill another AX78....

[Jethro]

Quad damage installed! So far 2.65ish at default volts... can use CMD 1 with rams which is cool! Can get to windows @ 2.8 but not stable yet! Just doesnt seem to like volts at all! My HTT clocking is dismal, super flakey indeed. Wouldnt even do over 202 initially but now im at 218 and climbing.. Board definately not comfortable with phenom clocking, definately fun to play with tho 15 degree celsius idle temps are insane!!

[Cheffy]

using soundood's method, above, and with cpu/ram/gfx all at stock (12*266 fsb) - ~12500 3d marks (vs 11000 overclocked single card). both cards runing pcie 2.
the board certainly can do xfire.

[Venom-Crusher]

my AX78 results with x2 6000+ F3 by regular water cooling.

[Cheffy]

Very nice, can i ask what bios your running? im guessing .13 - high v-core for an x2, how are you cooling the fets?

[hokiealumnus]

It's BIOS v.13 (build date 5/23/08). Great clocks there, especially 600Mhz on the memory. Very nicely done!

Regular Water for CPU & Air Cool for mosfet by stock heatsink.

Thank you

That's not possible! 31C on Core0 and 20C on Core1, using plain watercooling, at 3600Mhz, at 1.6xxVcore, you must live in Alaska !
