ddr2 corsair + kingston probably overheat?

post #1 of 6
Thread Starter 
hi all,

the system i'm using is in my details (hopefully).

at first i was using only the 2x2GB Corsair kit, but a week ago i bought the other Kingston kit. both of them have heatspreaders by default, Kingstons' being around 2cm higher. they are in the slots 0,1,2,3 -> corsair kingston corsair kingston (away from cpu.)

each kit shows no errors in memtest when using separately on a 1066MHz frequency.

when used all at once, normal system usage seems to be fine, but the Auto settings of the frequency set all modules to 800MHz and when running memtest, pretty quickly an error comes out.

what's interesting is that it always comes up in the third bank, right where the lower corsair sits between the higher kingstons.

could this be caused by the (now) insufficient heat dissipation from the corsair module? do you think that getting a heatspreader could solve the issue?

thanks for any ideas.

PS: yes, i was aware that combining two different kits of RAMs is always a lucky shot... but my corsairs are not sold anymore, i found nothing on ebay and the kingstons were still cheap enough to be worthy of investment...

I can't speak from experience, but it sounds to me like this is due to differences in their specifications/stock settings. So can you post all of the stock specs for both kits please?

Thank you, Eidam655! smile.gif

Also, if you want to know whether or not they're overheating, then physically touch them with your fingers. If it feels like you could keep your finger on the heatspreaders for several seconds or even several minutes without ever being burned, then the temps are very safe However, if it feels like you would be burned within a matter of just a couple of seconds, then that would be a cause for major concern. I mean, even just 45°C is only 113°F.

thanks for the reply, TwoCables smile.gif

both of the kits have the highest common JEDEC specification as follows:
1.8V 5-5-5-18 @400MHz

the Corsair kit has then an EPP profile, running safely at
2.1V 5-5-5-15 @533MHz

the Kingston kit has no higher spec (at least according to cpu-z), but the official site claims
2.2-2.3V 5-5-5-15 @533MHz

meanwhile i found out that the modules were actually picking up the heat from the graphics card and that my case fan is useless when used on lower rpms (80mm 1700rpm).
so what i did was that i turned up the fan speed (to its original 2700rpm) and moved the GPU from the primary PCI_E slot to the lower one and can now run the memory with the voltage set to Auto and frequency of 1066MHz without any problem.

in near future i may try the original constellation of the components with only the case fan turned up and see what that does; because i've always had problems with the GPU overheating (94C and not stopping), and although the idle temperature dropped from 62 to 53 degrees Celsius, the low space between the card's fan and the case hurts the cooling performance.

but that's probably for another topic smile.gif

You're welcome, and thank you for the update!

I admit, I can't resist asking: do you really need more than 4 GB?

I know that I should assume that you do since you're going through this much trouble to have more than 4 GB, but I've also seen many people here on OCN trying this exact same thing when it turns out that 4 GB is enough. So, that's my main reason for asking: it's the only way I can know (I'd rather ask than assume).

well, although i am a pc enthusiast, i study architecture and those extra 4GB come in handy when you're working with scenes in 3dsmax and/or photoshop and/or autocad smile.gif

Oh, ok cool. smile.gif

I hope that you get the temperature issue taken care of (I know something like that would drive me nuts). I'd like to take a shot at it, but I think it's over my head a bit.
