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

[superbowtie]

is it just me or are you guys noticed that the vcore is higher in Guru then in the bios with the latest beta bios 12.B08

I mean with 12.B02 it was higher but now i'm got like 1.475 selected and it will show 1.50 or 1.51. where as i'd have 1.49 showing. btw what do you guys consider safe for 24/7 use? anything under 1.6?

seems 12.B08 is better for crossfire 3870's I picked up like 10fps on average it seems.

ignore uguru temp...use the latest version of coretemp, 096, to measure your core temps.

[karlpox]

here my setup

intel c2q q6600 G0
Crucial Ballistix Tracer DDR2-1066

im currently stable 356x9 3.2ghz

cpu core volt vid 1.35v
ddr2 volt 2.1v
mchi volt 1.3

i tested this setting from previous post 3.6ghz

cpu core volt 1.4125
cpu core offset 0.0100
target cpu core 1.4225
ddr2 volt 2.1
vtt 1.33
mch 1.45
ich 1.15
ichio 1.5
ddr2 reference default
CPU GTLRF 0+2 68%
CPU GTLRF 1+3 67%

i even raised the vcore to 1.45 but i cant run prime95 for 20seconds 1 core will drop and then i get bsod/reboot. any advice?

Hey guys,

it's done - new IX38 in, old one out.
Plus full mobo cooling now, will post pics later.

[Supershanks]

I have good news - Mr. Franke from Mips-Computer just e-mailed me some pics of the new IX38 waterblocks. He gave me permission to share them with you, so here we go - enjoy

Blocks look great jcool , thanks for sharing.

Great news with your board, good turnaround

will post pics later.

Look forward to them

[jcool]

Ok so here we go, just some quick shots again, I just don't have the time to take some decent pictures




I decided to stick with a passive cooling solution for the SB, using a Zalman NB47J that already proved its effectiveness on my old AB9 QuadGT

So far the new board looks good, not the faintest sound coming from the PWM area - i certainly hope it stays that way.
Haven't flashed the bios yet, still running 11.B02 which was on the new mobo. I must say that this bios is way faster than any beta 12, has way more bandwidth and gives about 300 cpupoints more in 3dMark06 with the same CPU clock. However EIST isn't working correctly and Tras is way off, like everyone here knows.
Whatever, I think I'm gonna wait till they restore performance of bios 11 AND fix all the bugs with a new beta or final bios.

[generics_user]

i just received the board and my ram, installed vista x64 (can't find my xp64 cd....) and have no sounds or anything else coming from it.

chipset cooling seems to be very good, but i also attached a 40mm to the northbridge HS. i can't say anything about OCing so far as i'll wait for my replacement pair of 3870's until i start with real ocing and get hold of a replacement xp cd.

bios is well organised and the board is rock stable so far (just like any other board from 30-400$ with this cpu

i'll post some pics and results when my 3870s return from RMA (they died together with my old amd system)

[Supershanks]

I decided to stick with a passive cooling solution for the SB,

Think that makes sense myself sb doesn't get that warm. Think SB gets warmer using the original heatpipes. I have a temp probe on the nb & SB side of the heatpipes & have never known such a warm sb. I think basically the heay has just come from the nb.

Though i've not benched 11 12.06 did give alift from 12.02 which 12.08 has sustained. I don't think official 12 will be that far away. maybe next week??


Hi generics_use, you'll find the need dfor a fan on your pwm once you start ocing There's an MS driver than needs installing with the sound, sometinmes it goes missing on install Look forward to seeing the pics

[ante_ante]

Anyone tried an wolfdale E8500 on this board ??

[jcool]

I would if I could get one...
Waiting for small Yorkfields anyway, that Q6600 of mine just gets too hot for my taste.

[karlpox]

@jcool
what pwm & nb block are you using? it looks good.

[Supershanks]

New Bta out, thank's to Gilgamsh for sending me it

M704b_12.b09
Not checked 1:1.25 strap yet. Note I got a C1 error updating, may be my sloppy flashing, but if you do update be careful. If you have issues please feedback.

i just flash using 12b09 and doesnt give me c1 error so the bios should be ok

my d9 can run using 1:1.25

440x9/550@5-5-5-15

last time only my "superchip" ic that can use that setting now my d9 can use it also n pass 3d

give it a try

[R*r]

new bios rock

http://valid.x86-secret.com/show_oc.php?id=297452


http://valid.x86-secret.com/show_oc.php?id=297453


so whats limiting the max fsb on 1:1.25/4:5 i use the same voltage as the 1:1.5/2:3

vtt or vmch?since vmch i already set to 1.85v which i think its quite high for air cooling

any body know how to mod vtt

[Humble]

Seems with this latest BIOS, this motherboard is starting to show it's real fang now. The 1:1.25 divider and wrong temperature limit offset have been fixed. Can't wait for the version 12 final BIOS!

One more thing to check is does this new BIOS also fix the "Load Profile" function in BIOS? I had tried this feature in 12.B06 BIOS, and it was not working properly...

[Supershanks]

Cheers guys will try 1:1.25 nyself , not had chance yet, from those results look like i may be ok

Nice one

[jcool]

Nice will flash to B09 l8ter

@karlpox: see post #650

Aside from RAM dividers, have you guys been able to get higher CPU FSB overclocks with the 12b09?

I'll try it out later on today. Just waiting for my prime95 24hr test to finish up. I'll be very happy to bring my current q6600 to 3.6ghz. Right now, it's at 3.465ghz.

Anyhow, I've also noticed, if I push my MCH to 1.4v, the computer crashes as soon as a load is put on to it. I assume this because of the passive cooling, and I got my 40mm fans in today, so I'll see if that makes a difference.

Otherwise, the board has been good. I've been able to push my g.skill ram 800mhz (4x2gb, 8gigs total) to around 940mhz easily at only 1.95v, and no issues.

[Supershanks]

CPU FSB overclocks with the 12b09?

that' for trying tomorrow, can only have so much excitement in a day

Tried 1:1.25 M704b_12.b09 Initial Feedback able to bench like R*r at 8x470, but C1 on reboot. more info at bottom off link.
Got same at 8x450. May need to do a bit of tweaking.

good going with ram remodel

cheers old boy

Will work with abit as much as aI can to get the remaining issues addressed

Will keep you updated as things progress buddy

can anyone help me with this one?

ive just recieved the Abit IX38..

i have flashed the latest bios beta09.. i am running a q6600@3825(425x9@1.39v load) with a TT 120 Ultra Xtreme... thing is i have just switched form an Asus P5E and with the same CPU and cooler i had at this same frequency and voltage. Anyway the temps are much higher now ... i was getting like 35-36C IDLE and now i have like 45-47C.. also load temps are higher 78C vs 85C.

i have all teh cpu options set to disable in the bios .. just like on Asus..

also the pwm are hitting 120+ on quad priming...although i have a fan on the pwm rad.

any advice?

[jcool]

Erm... your CPU is actually stable at 78C coretemp?!
Mine flukes out at about ~68C... as does about any other G0 Quad. Is that a B3 you got there? Would explain PWM temps and why your CPU can handle that temp. What current readings are you getting with µguru?

[redmodel]

I had my G0 Q6600 completely stable at 85c as well. I was really surprised to see it going at that temp... Of course I've clocked it down after. With the Ultra Exteme too.

With the new bios, i've been able to push my FSB to 3.5ghz stable by 8x438mhz.

[xwoodoo]

@jcool ... its a G0 ofcourse ... anyway i had it running for over 1 hour @quad prime on the P5E .. @ 78C... on IX38 it heats up to about 85 and sometimes between 8-13 test in quad it reboots

In the uGuru it reads 1.38-1.39 V in load and i even got a record high 125C on one of the PWM's anyway 4 of them are over 110C .. i think i will change the rad on the pwm or stick with the Asus .. also 60-65C @ CPU on uGuru readings =)

other than that this morining i opened up the window .. its winter here.. and let it run at the same speeds on the abit and voila .. it ran fine for over an hour .. temps being 68@cpu and under 100 on pwm's

still i dont know why i get higher idle and load temps on the IX38 than on the P5E.
