**Official ABIT IX38 QuadGT Review/Overclock/Guide Thread**

[Humble]

Need more info what fsb are you running with Ram timings & voltage??
what vtt have you set??

either try making some retension wire from bending paperclips, or find somwhere to wedge a fan that fits. I'm running atm with a60mm fan that wedges in between my heatsink retension bolt & the back of the case.
Rubbish picture but you get the idea

FSB: 9 * 333 Mhz.
DDR2: 1000 Mhz @ 5-5-5-15
Vcore: 1.2875v.
FSB VTT: 1.25v
vMCH: 1.3v
vDIMM: 2.0v.
All other settings are at it's default state.

Thanks for the tips and picture about the fan bro. Get a little idea now. Gonna add a fan soon, before trying higher OCing. It's the PWMs heat that push me back before this.

I'm reaching a max of 70C on water, which is perfectly fine for 24/7 use. With stock PWM cooling and no airflow in the area I got close to 100C, which was still stable. Officially they are rated for 135C but anything over ~85C will shorten their lifetime considerably.

This is what I'm afraid of.

...even though a shortened lifetime still means several years with these solid state capacitors

Glad you've got an idea, it's annoying that we have to mess about finding a solution for the sake of a few pence worth of clips.
We may or may not get the clips that are shown here

But it is worth doing. my 60mm fan is giving me temps similar to jcool as we've mentioned earlier in the thread. See this post for my temps PWM Temps

luck

say i got this board yeasterday but im in a dip :
up multie dont work only down for QX9650 ,CF need's more power : it laks power .
if some one can fix this in a new bios the multie would be great already

Same as you, stuck with 9 multi on QX9650... too bad.

[blind_ripper]

idd u pay 200€+ for a board that has poor Cross-fire support and cant change multie !

Ace had it working fine (till it went pop) post 379 & 380, what bios are you using blind_ripper.

Has anyone seen this board under dry ice or LN2 ?
I'd like to know how the PWM's handle a quad @ 5.8 and 1.94volts.

blind, if you get the multi working, are you going to freeze it anytime soon ?

deanzo if it works for 100% il flash card's with 1.25vgpu bios's and run them @ 900core , cpu will be put under -100°C right away.
i have had it tested with the IP35 PRO but it seems that it's the wurst QX9650 ever , 5.2ghz on LN² with the F1 extreme and 5ghz with cascade on the IP35 PRO .
hope its the board and not the cpu : becaus i could do 1m @ same speed as 3D .

[TuKo]

Ace is running QX9650 with 11.B02 BIOS.

yeah had that one on it when i got it but Cross-fire is so sucky with that bios : like even wurser then 16x4x cf on the IP35 PRO .
if its not fixxed so il have to go to maximus extreme

[Supershanks]

have you tried 12.06 See BTA Bios

[strange|ife]

Hi again matey

Sorry I can see what you are talking about. I'll try to express myself more thoroughly now...

First I tried to follow your 400*9 template, but Prime failed right away with those settings. So i bumped up my Vcore to 1.4250 and lowered the FSB Frq. to 389 from 400. With these settings, as said in my previous post, one core failed after 1 hour and 80 mins. while the other three went on with no errors for 52 hours.

Okay, back to present time. I'm advices by Supershanks and R*r to bump up my VTT and MCH, but decided to try out 9*400 again since it seem to be a sweetspot for the CPU judging from the countless OC threads here.

So I tried with a higher VTT and MCH to reach 9*400 and this is where we are now

With these settings 2 of the cores fail immidiately:

have you tried 12.06 See BTA Bios

thx for the link , gone try this later on tonight

[blind_ripper]

no luck guy's : still stuck @ multie 9 with bios 12.06

[TuKo]

We're now praying for 12B07 to be released soon

[blind_ripper]

idd or im dropping abit ! this really sucks

[Ace-a-Rue]

i flashed the bios to 12.B03 and realized it wasn't a good bios at least from the standpoint of allowing me to raise the multi...returned to 12.B02 and that works very well with the QX9650.

yeah had that one on it when i got it but Cross-fire is so sucky with that bios : like even wurser then 16x4x cf on the IP35 PRO .
if its not fixxed so il have to go to maximus extreme

brought this forward so you know what bios works the best with a 9650.

[blind_ripper]

brought this forward so you know what bios works the best with a 9650.

so best bios is 12.b02 , and 12.b03 lets use change multie but its little wabky hu .
thx for the info

[TuKo]

Thx for the info Ace ! I'll give it a try!

[Humble]

Happy New Year everyone. Wish you all best of luck in this new year.

[Ace-a-Rue]

Thx for the info Ace ! I'll give it a try!

i do not have the board any longer so,i do not know if the bioses beyond 12.B02 work any better with the QX9650...i do know that 12.B03 won't allow for raising the multi on the 9650...it appears that 12.B02 is the one for Penryn's, ATM.

maybe you can experiment with the other bioses to see how they cooperate with the 9650.

yep 12.b02 is best for yorksfield , tested this morning .
unlocked multie and maybe tomorrow cascade on the cpu

Good news, I look forward to your findings mate.

HAPPY NEW YEAR to you too!

Comparing memset Performance Level Gigabyte DQ6 v Abit IX38 Quad

I've just been playing & would appreciate your input Scope for Improvement?? It's something i found between the gigabyte Dq6 & the Abit. would be interested to see if ny results are repeatable & therefore gives hope that we might expect a better performance bios , should the Bios engineers stumble across it and tighten settings. Alternatively it may prove my results are
just statistical quirks.

cheers.
