Yes...they do. I've experienced the same temp reporting with the KD7-E as I have with the KD7-RAID. System temps always read kinda high on both . Based on the sys temp research I did on the KD7 a few months ago, I don't worry much about the sys temps reading higher than we've seen on other Abit boards. Once i baseline the sys temp under normal operating conditions, I watch the changes in temp more than the actual value when overclocking. My original KD7-RAID has been running loaded sys temps around 43-45c for months under 24/7 load (folding) now without incident. The case it is in has exceptional airflow to boot. I don't sweat it any more:)Quote:

That is true Mike :)
My sys temp is always 6-8 degrees celsius higher than my CPU temp. Dont bother me as long as it doesnt rise much under load.
If you look at the motherboard pics you'll see that the location of the motherboard temp sensor is right up against the NB heatsink.
Does your KD7-E NB run a bit hot? Mine sure does and the air coming off that HSF blows right onto the system sensor.
I believe that OPP mentioned sensor placement as one of the things he'd change on the KD7, looks like it's one I'd want changed on the KD7-E.
How should I set up MBM5 to monitor the system properly? My system temp also reads quite high on the board, about 41c. My new Vantec AeroFlow HSF has knocked 13c off of my CPU temp over that P.O.S. AOC model I was using. I am very happy about that!
SPQQKY, look at your manual - the "system" sensor is next to the northbridge heatsink. All the warm air coming off that northbridge heatsink is flowing over the system sensor and heating it. You won't be able to get true ambient case temps on this board without an external sensor or without unsoldering that system sensor and moving it somewhere else.
SPQQKY,
What you want to do is take note of what your system temp is about 15 minutes after boot up when you're not overclocked. Consider that your baseline sys temp. From there just keep an eye on what change from baseline you see as you overclock and run for extended periods to get a feel of how things are sys temp wise. Remember your temps are relative measurements. It's really the fluctuations that matter.
To be honest, sys temp has always been one of the lesser important temps for me to watch anyway. I'm very careful about having very good case cooling, so there is not much more i would do regardless of what the sys temp sensor reports anyhow. Far more important is the CPU temp.
I went through the same thoughts you did when I got my first KD7-RAID which reported the same high sys temps. sjohnson is correct about why they read so high...tucked right under the NB hsf about an inch from the mosfets. I think abit did this on purpose to be honest. The KD7 series offers some crazy high voltage options, and i think the high sys temps keep the noobs from doing something stupid. Just my guess though.
Bottom line...don't sweat the sys temps. But keep an eagle eye on the CPU temp:)
I agree. I've gotten so aggravated looking at it reading 45-50c that I took it off MBM readings and just read my CPU temp.
I am not worried about the system temps, just saying it reads higher than I am used to. I know my case has good cooling. I was fully aware of the temps reading higher on this board than I am used to before I got it. It doesn't bother me, I know it will be any large fluctuations or spikes that I will worry about. I put a Vantec Iceberg on the northbridge, so I know it is cooled good enough. I just wanted to know which sensors I should use for the board. I have a secondary temp sensor from my Enermax multifunction transfer panel that I can read case temps from, in fact, I kinda like the sensor being close to the northbridge.
Okay:) Sorry if my post sounded like a lecture...didn't mean to make it come off that way:) It looks like you have a very good grip on the aspects of the board and what to expect.
I'm unfamiliar with your Enermax multifunction transfer panel, so I can only tell you that I use the Winbond 1 sensor to monitor sys temp in MBM 5.
I think you have it pretty much sorted now anyway:D
Bad luck for me, my Radeon 8500 died on me and now I believe my psu is going bad. I am getting low voltage readings, which is what may have been wrong with my 8k9a2+. I am back to a Radeon 9000 Pro and a new psu is on the way.
Sorry to report that my primary IDE channel went bad. Thought it was the disk, then the cable but the disk checks good on another system and several different new 80-conductor cables were tried without helping.
The disk was a Maxtor and the current MaxDiag couldn't even identify the drive for testing. Installed in my kx7, the disk tested completely recertified without error under MaxDiag. My KD7-E is already boxed and going back to Newegg.
Symptoms were increasing length of shutdown and frequent re-cal clicks and buzzes. Just before I tried to test it, the shutdown from Win2k took over 10 minutes. Again, the drive itself checks out perfectly.
This question is for MrIcee, mdzcpa, SlimHitman, Duran and others who are having high FSB success with this mobo.
So far the highest FSB I can reach with my combo listed in my sig is 190. If I bump it to 195 I get lockups and freezes in games and benches. I make sure my multi is turned down to 10 just to eliminate the CPU so that's not the issue. My memory setting is at Turbo, Enhanced for Benchmark, and all others are default.
I'm thinking it's the memory timings I need to play with to get 195+ but not sure which. Also, I'm not sure which Corsair stick I have since the person I purchased it from removed the white sticker. Sandra says it 2700 but I'm not sure if Sandra is that accurate anymore.
Of course, it could be the 9700, but I would think it should run 78mhz.
Any suggestions to try for 195+? TIA!
Sandra says i have SDRAM, so dont bother :)
My suggestion is to set your RAM timings to lowest possible to eliminate that, try disable UDMA(shouldnt be necessary though) to eliminate the HDD, try with another GFX card. That is what i think is most likely, even though Mike is running his Radeon at 200mhz fsb.

SPQQKY:
Sorry to hear of the demise of your 8500. keep us posted when things are back in order. I am curious as to your results with the KD7-E.
sjohnson:
Wow...an IDE going out sucks. Sorry to hear it. Are you going to get another KD7-E or go for something else?
bigdawginva:
It could be a number of things, but I think you have keyed on on two better possibilities...the memory and the 9700.
I run my memory timings set to Manual, CAS 2, 4 Bank, 2,6,2. I have also raised the memory voltage to 2.85v. These settings work great with my Corsair XMS3500.
Now depending on which memory you have makes a big difference. If it is reading as PC 2700, my guess is that you have either Corsair XMS2700 or XMS3000. XMS3200 and XMS3500 usually read as PC3200 memory under Sandra. If this is the case, you will need to work much harder to achieve higher FSB speeds as you'll be pushing the memory harder.
There are two things you should do. First, relax the memory timings to CAS 2.5, no bank interleave, 3,7,3 and see how high you can go FSB wise. If you find an improvement in how high you can go, we'll know it is the memory holding you back. If you have no luck with relaxed settings, make sure you've tried upping the memory voltages too.
If relaxed memory timings do not get you any further, I'd suspect the R9700 or another component is holding you back. So the next thing to do is try another Vcard.
My R9700 has no problems running high FSB speeds on this mobo, but that's not to say everyone will have the same success. The R9700 is a finicky card for sure.
This should get you started in your investigation I hope:)
Looks like DuraN has you covered already...sheeze I type slow:)
BTW, hard freezes do sound more like video card trouble. Memory instabilities usually lead to BSODs or CTDs (crashes to dekstop) when benching/gaming.
But...let's take it one step at a time.
Thanks so much for the help. This is the most advice I've gotten in awhile so it's very beneficial.
I ran Sandra and again it reads my memory as Corsair CMX512-3200 512MB 16x(32Mx8) DDR-SDRAM PC2700U-233-700 (CL2.5 upto 167mhz) (CL2 upto 167mhz).
I checked the Cosair pdf for this stick and the SPD is probably programmed to read the PC2700 piece but I'm confident it's reading the CMX512-3200 correctly.
I have the vdimm set at 2.85v currently. I will try to eliminate the memory by trying the suggestions.
Currently, I am running the CPU at 190*12 @ 1.85v
Thanks again!
I think you are right about your memory...it definitley sounds like a 512 stick of XMS 3200. This is good.
Try relaxing those memory settings and let's see what happens:)
Have you tried raising the vcore bigdawg?
I am still stuck at 213fsb at fastest settings.If i lower the timings and try 214 it messes up windows,one time it messed windows at 211fsb. Still waiting to find a good deal on a used Seagate Barracuda IV, i heard they are good for high fsb.
Check out these voltages. I think this has to be a failing PSU, this was happening on my old board as well. The fluctuations and lows are to extreme for my liking, even if they are within 5%.
BTW, the vcore is set to 1.725v and another note is my vagp is only 1.53v instead of 1.57v.
SPQQKY:)
Your AGP is about right for the KD7....I've run 3 and all 3 ran at 1.52v. Also, the Vcore flucuation is also not unusual on an ABIT board..or at least mine, your 3.3v line looks good. My concern would be to strengthen your 12v and 5v lines, they are both under what I would like to see. Strengthening those lines will also aid in keeping your Vcore strong under load. Not sure if you can tweak the +5v and +12v lines on that Antec, but if you can I'd start there.:)
Randi:D
MrIcee never sleeps either;]. I was thinking basically what you said above. The KD7 loves to chug on that 12v rail even with the extra connector as many have seen and may be tough to bring up. I honestly don't think the power supply is failing though. At least not from these readings alone.
Tiribulus:D
There are no adjustable pots on the Antec TruePowers. And after puting in the Radeon 9000 I haven't had a single lock up or reboot, which seems obvious that the 8500 was what gave me all the grief with my system and not the psu. So far the system has run for 72 hours straight without a hiccup.
Good news SPQQKY:)
I've also noticed the same kind of voltages on my KD7-RAID and KD7-E....but they have caused me no troubles whatsoever. I think Randi has once again hit the nail on the head with this KD7 issue:)
My +12v is hovering around 11.80 all the time, although my +5v is stronger, like 5.08-5.11. Im currently using my Antec 340W, but its the same with my Chieftec 340W. On the other half, my brothers 350W Enermax would not cut it with this board.
Btw, my AGP is 1.55v steady, not moving at all :)
