A7N8X Deluxe and RTC

[Egil Solberg]

I have the A7N8X Deluxe ver 2.0
XP1700+ (Palomino)
Running at 133MHz (stock)
WinXP pro SP1

As I got the mobo I would try running at 140MHz, even if system was stable
at 145MHz.

I have run into some problems, not stabilitywise, but lagging in games, and
general jerkiness. 3DMArk2001 scores are more inconsistent when running at
140MHz.

I noticed my system time was running too fast, catching on at around 15-20
minutes during a day, or so it seems. Checked for some minutes towards my
wrist watch, and yes, it was gaining. Went to BIOS and yes, it was gaining
there as well, the time was at least the same as in Windows.

Backed down to 133MHz FSB again and now it seems better. Have checked now
for around 15 minutes, and the time keeps relatively steady towards my
watch.

Is it a knows fact that system time speeds up as FSB is increased? Is this a
bug? I would think so. Earlier I had a P3 system that performed fine and the
clock kept fine and steady even severly overclocked (144MHz).

Can anybody confirm this? Is there a fix? Can it be fixed bu let's say a
BIOS upgrade? I run 1.007.

There have been issues related to the system clock, I don't fully recall
them.

Possibly the cmos battery needs replacing.

Hi, thx for answering.
With power disconnected the whole night and today (just came back from
work), the clock has been fine. So the battery should be OK. This is
strange.

(144MHz).

Unfortunately they don't mention anything there. I use a web-TV feature
which requires WMV-streaming (www.tv2.no/webtv). It has been running fine,
but after I switched to 140MHz FSB, I got problems. Always connected at
591kbps, then renegotiated 391, 209, 192, 83, 43kbps. If I stopped it and
restarted I would start at 591kbps again, and this would repeat. Back at
133MHz now and it runs fine again.
My system ahs been very stable at this small overclock, rnning Prime95 and
3dMark2001SE. No errors in memtest either, just this annoying clock speedup.
Anyone experienced this?
