Things seem very very expensive in europe - then doubled again in england!

My quad core is up and running - one quick question for comparison:

Using core-temp I'm seeing

55c
58c
52c
53c

When rendering in maxwell. I'm surprised to see so much variation between cores - is this common?

Thanks,

Kandor

yes this is normal. the quads have two chips under the heatspreader (here 1. 55+58° and 2. 52+53°) and it depends on how well the heatspreader fits on both of them.
the 58 to 52° difference is not optimal, but it should be no problem. but the 58° core could be the weak point if you plan to overclock...
i have around 4° difference between the lowest and highest temp.
to preclude a bad mounted heatsink you could reseat it (and maybe apply a good thermal compound - e.g. Arctic silver 5 - if you haven't already done.)

but your temps look good - assuming that you are using air cooling, and considering that it is summer. so it could be that remounting will have no effect...
and 58° should be no problem for a quad - from 70° on you can start to worry
i can easily reach 60-68° with my 3ghz q6600 - depends on the ambient temp.

...so, and now look how far you can go

Thanks for the info!

I will overclock once it has a chance to set. I'm used to the e6400 chip that I had overclocked 50% to 3.2ghz (from 2.1) - it use to render around 52c per core (overclocked) and in the mid 40's without the clock.

Here I'm already hotter at stock.

I have used AS5 for years but on this system I tried the zalman stg1 grease which everyone is saying is as good or better than AS5. I'm using a cnsp9700 on my quadcore chip. It's the first day so once the compound sets (in a week) I may see better temps.

Ps - it's around 34c here today (record in canada) - but my office is thankfully in the lower level of my house with air conditioning

Pps - how are you oc'ing yours? Are you changing the multiplier or just the freq.?

Hello guys! Sorry for my novice question but it is possible install two quad 6600 together(8 cores), i mean, i´ve been looking for mother boards that support 2 quad 6600 but i can not find it.

Thanks in advance.

[numerobis]

yes, the quads run very hot...

i have increased the fsb - higher multiplier only works for the qX's... normally.
...and higher fsb = faster system

Tcase max for q66 is 62.2°C (ihs temp)

so, i think ~15° more for the coretemp should be ok, but i don't it know exactly

no, it's only possible with the expensive 53xx Xeons for socket 771...
and you need registered ram for these boards

Thanks numerobis, them i´ll buy a 6600 quad when the price low.

Rendering in modo at stock (modo is hotter than maxwell) I get

49c in speedfan and then speedfan lists 4 core temps that seem too low:

41c
45c
40c
40c

Meanwhile coretemp reads:

56c
60c
55c
55c

So not a lot of headroom there - I'll let the compound settle for a few days.

[numerobis]

the speedfan temp should be Tcase or cover temp, coretemp reads like the name says the coretemp
coretemp should be more exact - speedfan only reads the bios temp

so - theoretically - with ~40° Tc there is ~20° headroom up to 62°

[b-kandor]

I thought the speedfan temp ~49C would be the Tcase so hence I'm thinking 10-12 headroom - which is still fine.
