Hello, I have just upgraded to an MSI K8MM ILSR mobo and an AMD s754 Sempron 3100+. I have built another system with the same CPU, but different mobo, and it ran at 27 - 34 degrees C, and from what I understand and all I have read on the net that is where this chip is supposed to be. Also, that system was fast as hell! For some odd reason, mine is hard to keep below 55c and is running quite slow. Anyone have any issues like this with this chip, or anyone may know the reason why?? ... I am thinking maybe defective CPU but just wanted to see if any of you have any other suggestions first. Thanks
I think maybe you have'nt installed the heatsink correctly, remove it and install it again, also what speed is the fan running at? are you using thermal paste?
Fans are fine. I first used the stock AMD fan with its stock thermal pad, installed correctly, had the problem with that. I then switched to a Zalman 7000b-Cu using the paste that came with it, although it was much quieter, still have the heating issue. I have changed the CPU since, and still have the heating issue, and its running like crap. I am now assuming that this MSI motherboard is a peice of shit, and I am thinking of dumping it for an ASUS.
It may be the power supply not being powerful enough, what are you using? and try the cpu in the other known working motherboard to see if the temp drops
Its a Top Power 350W .. plenty of juice for this setup. As this is my second CPU I dont need to try it on the other board, its obviously not the chip.
MSI is a pretty respected brand in motherboards. Hmm, there are screw ups every once and a while though. Usually 350watts isn't enough, top power sounds like a generic brand so you got two things goin against ya there
Top Power is far from generic, it is as good as, if not better than enermax, which I replaced with this Top Power due to its noise levels. You cannot get a better power supply for the money, so that is something good going for me. You are right about MSI though, and maybe I just got a lemon. .... oh, and 350w is plenty for a Sempron of anykind.
A Top Power 350W PSU should be fine for what your building, I would make sure that the Vcore for on your Sempron 3100+ isn't more than is needed. Also check via the Bios that your Voltage's are sufficient, if you are unsure or cannot view them via the bios then i suggest downloading Motherboard Monitor and using that to view your Voltage's. I would like to see the Voltage rails on the powersupply if you could list them..? and perhaps a screenshot of motherboard monitor showing your voltages. Bare in mind this is a 754Pin 64Bit processor and may require slightly more power than you think.. personally i've never come across a 64Bit not even a low end 754Pin like the 3100+ Sempron utilizing a 350W PSU.. but you never know.
You also might drop by MSI's website and see if there's a BIOS update that addresses your particular issue.
Yes, make sure you have the latest BIOS Revision, then you can eliminate any possibilities of onboard temperature mis-calibration.
Thank you all for your suggestions, but I have tried everything here, just about everything I can, other than changing the motherboard. I have checked the bios, and its revision, and the power supply, and evern swapped CPUs. The first system I built is running with a cheap generic 300w and is still at 27C so I know the power supply is not the issue. I really am at a loss now, I guess I will have to try and change the motherboard now and see what happens. I don't know what else I can try.
