HI Guys i have been doing some research and i cannot find for the life of me the thermal specs of EEC buffered RAM. The unit is a Dell Precision 490 and i have 4 gigs in it, and speed-fan shows the temps at 70 Degrees Celsius. I am a little concerned that this is high, but its about the only part of the system I haven't tinkered with so its all stock speeds and stock (VERY NOISY STUPID FAN) cooling. This going to be a folding rig so i am posting here first. Cheers all.
Hi, Yes DDR2 FB memory runs really hot, that's why they have built in heat spreaders, I can't remember the thermal limit but 70c doesn't sound unusually hot.
Cheers Dave, If anyone knows how to find this out it would be useful as i am concerned that the OEM cooling in this case is shite! If I am to fold with it I want to make sure everything is well under the manufactures specs for longevity. I have remounted the CPU coolers and they actually prove quite effective with OEM cooling keeping them sub 55 degrees, but with speed fan switched on, i can crank up the front turbine (yes it is that big and moves some serious air) and get these temps down into the mid 40's. The GPU cooler has been upgraded and will now fold at 60 degrees with fans on max. (GTX 470 ) So the last "warm" item on the list is the ram. I did try splitting it up so that there was more room between them but totally forgot that these boards are not configured in the same way most boards are and it switched to single channel mode reducing the amount to 1gb I did install 2no 80mm fans in the case at the back to draw more air out of the PC but this had a negligible effect. I also now need the molex supplies for the second pci power lead to serve the GPU, so did away with them. I did try an experiment with removing the fan from its mounting and cutting a hole in the side panel and re-mounting it to draw cool clean air in to blow across the heat sinks. This again didn't do a great deal so i have reinstated it back to factory positions etc.. The main problem i have is that again because this is an OEM board, i don't have any spare fan headers and cant mount any extra E.G a ram cooling array to further aid heat dissipation. I did think about after market heat sinks for the ram but I couldn't find any compatible for EEC ram. Anyway, my quest to improve the cooling continues......................
On the memory I've just checked the max temp is given as 95c and I would have thought most would be similar, only way to be certain would be to look up the specs of the sticks in your machine.
OK well my new copper heatsinks have arrived. Got these from Scan at a nice price. http://www.scan.co.uk/products/xcli...dr-ddr2-3-with-3m-thermal-bonding-very-hi-end Also got me a couple of SATA to Molex adapters and am going to shove my extra Sharkoon fans back in. Or more specifically one on the back of the PSU and one on the back of the GPU section of the case. The PSU is passively cooled and its getting uber hot. Also the Zalman cooler doesn't push the air out the back of the case so im going to create a small push pull setup to further aid the internal case temperature. After this i can do no more and will run the gauntlet with switching her on 24/7
