ABit AX78 Overclocking/Stability

[flips]

so everything is just fine now..but i haven't that many experiences in memory tweaking and want to know if there is anything i can improve on the subtimings?!

here is a memsetscreen:

[LIKMARK]

The AX78 is not a memory tweakable board sad to say. You could try to make it run 4 4 4 12 2t 1000MHz, that would be nice Don't know what voltage your ram is specified for though.

[SocketMan]

Maybe drop the cpu Multi to 10, HT multi to 3,and see how high it will go,you cpu is at least good until 3000MHZ (10x300 HTT) test stability as you go.That CFX3200 of yours can do 370+ on the HTT, with the right ram/timings

[flips]

i swapped the DFi for the Abit because the DFi wasn't able to handle my 4GB GSkill PC 8000 Ram with good clocks. So currently i have the Abit and i love it so far.

Maybe you can swap it out of your sig ?
So people don't get confused when they're trying to help.
I won't even go into what can handle what.

[Jethro]

My ram plays really nice on this board. DDR800 @ 1100+ cas 4 aint to shabby~!

[LIKMARK]

Nice Jethro, is that stable, and what voltage did you apply?

[Jethro]

[flips]

very nice OC,
but it's crazy that Everest reads RX790 Chipset, because mine shows AMD770... :/ maybe an older version...

[hokiealumnus]

New BIOS out; v.13 official. Get it here.

BIOS release V13 for AX78

Release information:

[ENGLISH]

1. Enhanced AM2 CPU compatibility.
2. BIOS compiled date: 05/23/2008.




[¤¤¤å]

1. ¼W¥[AM2 CPU¬Û®e©Ê¡C
2. BIOS µo§G¤é´Á: 05/23/2008.




********************************* NOTE *********************************
1. How to upgrade BIOS:

a. Create a MS-DOS startup disk.
b. Extract all files in the operation system.
c. Copy the files to startup disk.
d. Boot into MS-DOS.
e. Run "runme.bat"

*** Please notice that we suggest you flashing the bios with switches

"/py /sn /cd /cp /cc /cks /R" or by "runme.bat".

3. After BIOS updated, pull off the power cord and then clear the CMOS data
via jumper before restarting system please.


================================================== ==========================

Note that one user @ abit points out his 9850BE for some strange reason gets 1.54v after updating to this BIOS. Why, I have no idea. I believe he reported the problem to abit.

Aside from that, some users will be happy to know there is now a Ganged/Unganged setting in there. Haven't verified that myself, just what I've heard. I'm flashing to it shortly.

EDIT - I'm happy to report it does allow Unganged mode and, more importantly to early phenom adopters, it allows you to choose whether to use the TLB fix or not!

[Jethro]

Thanks for the heads up Hokie! Installed and running fine! AOD works perfectly still etc. I'll try pushin it later! Thanks for the Link.

[hokiealumnus]

No problem, glad to help. On a related note, if you're into F@H, I enabled the TLB Cache (disabled by default) and am getting just under 300ppd more with the OC in my sig folding project 2665. Yay!

EDIT - One last addition according to a user @ abit (I don't have a PCIe 2.0 card, so this one's beyond me) is...well, I'll let him say it himself:

hey guys. There's improvement at pci-e 2.0 x16 functionality. Set it to auto switch and it works! No matter how much I restart my pc and check again in gpu-z its pci-e 2.0! (in bios 12, pci-e 2.0 not functioning. And sometimes it does) So this new bios does made an improvements.

What about the NB multiplier option?

[hokiealumnus]

What about the NB multiplier option?

That's always worked for me. It's under Advanced Chipset Features / HT Link Control.

hi hokiealumnus, i still can't see the option even with the latest bios. any idea how to sort this issue out? without this feature i reckon it's kinda hard for b2 phenoms (with locked multi) to achieve high clocks (thou most of them are not good clocker).

another thing is why Abit doesn't allow undervolt on AX78? It would be good if such feature is allowed to reduce some temp on the chip as well as pwm.

other than these, the board has been great.

Hmm..that's very strange. It's always been there on mine. Start by disabling Cool N' Quiet if you haven't already (Advanced BIOS Features / CPU Feature). See if that enables your CPU multiplier. Then save & exit. See if you can then access the HT multi. Weird that it would be on mine but not yours.

Re: Under-volting - with all of their recent boards, abit hasn't done any under-volting. They set the VID as the lowest selectable Vcore. Some people would like to under-volt, but we're overclockers, so that's not bad news...there's nowhere to go but up!

i've disabled the C&C feature in bios but still can't see any nb multiplier adjust thou i was able to adjust ht multiplier.

i can still live with unable to undervolt's issue.

[Cheffy]

if you want to undervolt, use rm clock to move the vid down once in windows.
works fine

[hokiealumnus]

Hi again folks. Update on the 9850 Vcore issue - it's fixed by clearing CMOS, going into BIOS and selecting "Load Optimized Defaults"! The user hadn't done that previously and tech support suggested that. So, to summarize, BIOS v.13 is good for 9850BE's as well.

thought i would post this before Hokie did sry hokie,

Abit have updated there CPU compat list for there mobo's, interesting reading for the AX78, i am so glad i got one of these early, appaerantly they have went up $25 dollars on new egg,

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

[soundood]

i think i have heard of one guy doing it, but i dont think anyone wants to, or needs to do it.

there are just far too many single/dual gpus that re up to the mark for the money,

myself for example, i have a 9600GT graphics card, but im going to upgrade, now i would normally stick another 9600GT in there (on sli board) as they scale well.

or for the AX78 i will get a 4870x2 for that, why mess around with crossfire when i can have dual gpu's on a single card?

you know what i mean, , gone are the days of the only upgrade on a 8800gt was another for sli ,

but i would be very interested on the results, especialy after reading anantechs review on the need for x16 slots for sli or crossfire, they seemed to think it wasnt needed, and that 1 x 16 and 1 x 4 would not be a problem for most games in sli.

when i have two cards i will try it, im gagging to know, i bet the result doesnt suprise me

[SmaKKed]

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.

[hokiealumnus]

Haha...don't apologize to me. I've had no time recently. First time I've been able to peruse XS in a few days!

SmaKKed, i know you will be busy gettin it on with the new rig, but some crossfire and single slot results would be great, it would let us see if they scale well on the ax78

Haha...don't apologize to me. I've had no time recently. First time I've been able to peruse XS in a few days!

busy busy, tell me about it, ive got three kids on summer holiday at the moment, they are running me ragged

i sit at the comp at night to check emails and im falling asleep, while i can hear them planning and laughing about they will drag me into tommorow

help !!
