Abit IN9 32max Can't pass orthos blend test

Bazooka_Boy · 14 Mar 2007 at 20:22

This is my first attempt at building a rig with the plan to overclock.

Where I'm having problems is with the orthos blend test and some lock ups in windows that lead to BSOD (either 0x000000F4 or 0x0000007A Kernel_data_inpage_error).

I'm overclocking my E6600 to just over 3GHz and my Corsair 8500C5D to 1080. I have no temperature warnings and I can run MemTest v3.2 or Orthos Small FFTs for around 9 hours without errors before stopping the test.

But if I try to run Orthos in blend mode it runs for around 1.5 to 5 minutes before failing with a rounding error

Before running the above tests I did the following

I had already upgraded to BIOS 1.1 but I shut down the machine and cleared the CMOS then unplugged for a few minutes.

Powered back up went straight into the BIOS and loaded the optimized defaults.

Then set

SLI Ready Memory = Expert
CPU Operating Speed = Linked
FSB <QDR> = 1350
Multiplier Factor = x9
FSB Memory Ratio = 5:4
N/B Strap CPU = PSB1066
(giving) Estimated DDR2 Data Rate = 1080

Increased CPU Core voltage to 1.3650
DDR2 voltage to 2.2
Disabled CPU VTT Voltage Alarm as although High=1.45 & Low=0.95 a reading of 1.2 was triggering it.

In Advanced chip set features
LinkBoost = Enabled
Manually set memory timings of 5,5,5,15 2t

My current voltages are
CPU core = 1.3650
DDR2 = 2.2
NB voltage = 1.35
SB voltage = 1.5
CPU VTT = 1.20
DDR2RefV = 0%
HT voltage = 1.4
NBDDR2RefV = 0%

I've run a couple of games for a couple of hours, but if I leave the machine at the desktop with nothing running it seems to reboot itself within about 30 minutes and sometimes although its at the login screen nothing responds and I have to reset. Often after a crash I get stuck in a loop at the windows xp logo screen or if I log in and try to open an app or the start menu straight away the system locks and I get one of the BSOD mentioned above.

Hopefully someone can advise me if my voltages are too low or if there is another testing tool I need to run to shed some more light on the problem.

Blend stresses the memory, cpu/cache and memory controller. I would suggest 1.4v vcore and 1.4v on the NB. See if that helps.

thanks for the reply. Unfortunately I up'd the cp core and north bridge to 1.4 but orthos blend still failed after 5.5 minutes

I'd drop the ext. clock (fsb) to something like 280-300. Run orthos blend to find a stable baseline, then bump fsb by 5 or 10 points and re-run blend to find the max o/c. you may try tweaking voltages after that to bump a few more out of it.

Also, try 1.45v on the NB and put a fan on the heat pipe as advised by ABIT. Disable Linkboost and don't use the SLI Ready/EPP profile. Turn that off and just use your manually set timings.

Also, have you loaded the latest final bios from ABIT, 1.1?

Bazooka_Boy · 15 Mar 2007 at 12:48

thanks yellowbeard

I'll try increasing the NB to 1.45 as I already have a 40mm Akasa on it already and the dominator fan on the ram. I turn off the link boost and I assume I stp using the epp profiles by changing the CPU Operating Speed to unlinked?

I'm running the latest (1.1) BIOS.

I'll try this first as i went straight to these overclocks based on a friend who has an identical setup (aprat from CPU cooler and flavour of 8800).

If that is not sucessful I try MK17 suggestion.

I'll keep you posted, thanks for the advice

Bazooka_Boy · 15 Mar 2007 at 20:22

ok I disabled SLI-Ready Memory
set CPU Operating speed to unlinked
FSB to 1350 (to give 3037.5 MHz) with multiplier of x9

set MEM DDR2 to 1080 as if I set it anywhere from 1061 to 1079 it shows DDR2 rate of 1060.7 and I read that whole even numbers were better.

set N/B strap CPU as PSB1066

increased NB voltage to 1.45

disabled linkboost

I ran the blend test and this time it ran for almost an hour, but then I got the rounding error. So a set in the right direction but I think it should still run for much longer without an error.

After stopping the orthos belnd test the machine was sat there doing nothing whilst I was working on another PC and then I got a BSOD (0x0000007A Kernel_data_inpage_error)

Bazooka_Boy · 16 Mar 2007 at 14:34

I'm not sure which of the above changes would have enabled me to run the blend test longer (lesson not to change so much at once). I think I'll try an increase of the NB voltage as I have the chipset fan on it. Unless anyone would recomend against it

It seems like on my board, anything past 1.45v is only adding more heat and not adding any stability but, give it a try. You won't damage anything.
