GPU temps...

Do ‘we’ think that 85 degrees C is too hot for an HD 4770 core temp (furmark burn-in test of 2 in crossfire – other one only reaches 74).

I’ve stripped and cleaned both cards. Put on new thermal compound. Didn’t temp test before the clean.

Under load that doesn't sound like bad heat. Out of curiosity, you could do
a simple test to determine where any problem might lie: swap the cards --
if the 'hot' moves then you know that one GPU or its cooling setup is
probably at fault. If the 'hot' doesn't move with the card then it could be
that the case's cooling is just worse in one position, possibly because the
video card air intake is restricted there or because it is sucking in more
pre-heated air than the other card in that location. If it is the 'inside'
card which is hot then that answer would be my guess.

Someone here had a bit of trouble at 80C, but perhaps this
result is an anomaly.

The silicon should be able to take a bit more than that, as a die temperature.

When video cards are paired, if the back of one card affects the
air input to the other card, that can change the temperature
a bit. One card ends up running warmer than the other. It
really depends on whether you have options for card spacing,
as to whether you can fix it. The poster in that thread,
underclocked a bit to cool the card.

BTW - You seem to be posting in HTML/MIME or something, as
you've hit the Eternal-September filter and your post didn't
show up on E-S. I wouldn't have seen your posting, if John hadn't
replied to it. Your posting style is allowed/transmitted on
groups like the defunct microsoft.* , but will be a problem
on some of the other groups which don't really allow it.
The policy may vary a bit from server to server, and filters
like that are put in place, after someone tries to abuse
that capability. There are plenty of neat "tricks" that
can be pulled, if that filter is not in place...

Thanks. The build is still open to the air - work in progress. I didn't say,
but the 2 cards are different brands, so different coolers. I was just
checking the max temp was OK. Once the case is closed they will actually
have better forced airflow, so temps might drop slightly.

Thanks Paul. I've just installed Windows 7 and I'm still using Windows live
mail at the moment. I've switched the settings to plain text for now. I'm
trying to find a decent free newsreader, but no joy. Thunderbird finds no
newsgroups for my account. Gravity doesn't group conversations into topics -
it just gives a flat list of everything and I can't find what reply goes
with what... What newsreader do you use?

An old copy of Thunderbird.

In terms of getting Thunderbird to work, you could try ticking
"Always Request Authentication" in the setup for that particular server.
This assumes the server requires a username and password. When you tick
the box, Thunderbird will prompt you for the information, then forward
it to the server. Some servers, allow both unauthenticated and authenticated
connections, and the newsgroup list can be radically different between the
two. By ticking the box "Always Request Authentication", that is to
try to get you the "more useful" kind of session.

A server like aioe.org, doesn't need to have that box ticked, because
you don't apply for an account there, and the session doesn't use a
username/password combo. So not every server needs the box ticked. But
if you remember presenting a username/password with that NNTP server
in the past, you'd probably want to tick the box in Thunderbird now.

Some news clients, support "threaded view" or "flat view". I used to
connect with a client that was only flat, and it was annoying as hell.
That was back at work. The messages came in, in "date" order, and you
had to scroll around to find all the bits and pieces. That was
some tool on a Unix box.

On a client, it may be difficult to figure out what to click, to get
threading back. If you accidentally click on the wrong column header
in the message pane, that can screw it up, and put it in a flat view.

"Custom View Filters

Starting with Gravity 2.1, a view filter controls both which articles
are displayed, and also how the articles appear on screen. A filter
may be set to display unread articles, but it can also control whether
the articles are threaded into conversations or not. If the articles
are not threaded, they can be sorted by From, Subject, Lines, Date or Score.

Each newsgroup can be linked to its own view filter. Use the small
"chain-link" icon found on the filter bar to link a filter to a group.
The end result is that every newsgroup can have its own customized way
to arrange articles. For rec.pets.cats, you would probably want to
use a threaded view. For alt.binaries.pictures.supermodels, you might
want to use a view that puts the largest line counts first."

The solution doesn't have to be intuitive :) Based on the newsreaders with
"200 hot key combinations", having any kind of a GUI at all, is considered
a big step forward.

HTH,
Paul

Good tip - swapped them over to test temps and they both run cooler - 67
and 72 now. One cooler exhausts air and the other recirculates. The
exhausting one is now on top and the recirculating one is on the bottom
with a little airflow entering the case from just below.

Nice one
