Well, every bone in my body tells me this board runs the voltage about

running this one kids.

However, least it's stable

Right now I'm running the setup above at 3.4ghz, 5:4 FSB/DRAM,
2.5,2,2,8 bus 405mhz dual ddr and it's still 1 notch under the default
CPU voltage in the bios (1.5125 I think)....I didn't up AGP/Memory
either....and this is a dead stable config.


FWIW, I'm not cluey about this stuff, but I do have my P2.6c running
at 3.14 (ie, bus at 242) on this board - but maybe not so stable ;-)

At lower voltages, Prime 95 torture test won't make it through first
test without failing on hardware rounding error. With higher voltage
(one notch above normal), I get to second test before it hits a
rounding error. So probably only concern for daily use when I do
heavy stuff for long periods (I think it crashed once before while I
was running Tmpgenc). Idle temp (stock cooler) is 39 - not sure I
want to set voltage any higher to try for more stable under stress
(temp was 63 when Prime 95 failed).

I set DIMM voltage at +0.1v cause someone said that would help with OC
stability too?

EasyTune reports voltage as 1.61, CPU-Z says 1.584, and bios setting
is 1.5375 - huh?

Anyway, I was running like this for a couple of months (242 with CPU
and DIMM voltage at one notch above normal based on someone else
recommendation) - but then board died and had to get it replaced under
warranty. Hope that's not a result of overclocking - time will tell
;-)


Not a bad overclock for an hour's work on a board everyone says can't
clock and some cheap $179 unmatched crucial 2.5/3/3/8 memory !! Now
If I can get it stable with 'performance mode' active on the dram
settings....Alogether runs about 14% faster through Sandra then stock.


CPUZ says memory "performance mode" disabled - I'm using DDR400 -
can't get it to performance mode enabled with bus well over 200 can I?

Hello all, hoping for some help.

I just upgraded my 848 based Intel board to the Gigabye 8IK1100, Rev
2.0. My hardware is as follows:

8IK1100 Rev 2, Bios FG (latest)
4x512mb Infineon Cas 2.5 DDR 400 (dual)
120gb Seagate IDE (Baracuda V)
400W Fortron/Source Power supply
P4 2.8 Norhwood (800 bus)
Sony 4x DVDRW
Sony 16x DVDROM
Nvidia 5200 Ultra Video Card
Zalman 7000 heatsink/fan

My issue is that the 2.8 has been running very very hot. I've made
sure that the CPU heatsink/fan is securely fastened and working fine.
This same cpu and memory were running in the on the 848 board in the
same case at 40 deg cel but after changing the motherboard I am
seeing 50 deg + cel (up to 60 under load).

The box also isn't as stable as it was...

The ram, board, bus, etc timings are all 100% stock (ie. no
overclocking) and CIA is off.

After much investigation I found that all utilities in windows (ie
sandra) show the CPU getting way too much voltage -- like 1.6 instead
of 1.525. I lowered the cpu voltage setting in the bios about 4 or 5
notches below "default" and now I'm seeing the correct voltage in
Windows (1.525) and lower temps that are more within reason (45-50 deg
cel at full load, 35 idle)

Has anyone else seen this on the 8ik1100? it's very odd!! I had first
tried a 3.2 gig Prescott on this board and could not get it stable and
cool....I thought it was because of the Prescott's new design (well
known for major heat)...now I wish I hadn't sold it because this might
have been the root cause.

Appreciate ya'alls insight.
