RAM cooling in the future

This may be a necessity before too long, as my current setup doesn't like me running my RAM higher than 1333MHz - I'm not entirely sure why, but every time I set it thus, it boots into an 'overclocking failed' message and resets the settings. Last time, it set my CPU multiplier to 12 and the FSB to 133, so I was getting a mammoth 1.6GHz/core out of my CPU (which I hadn't modified at all - still running at stock til I get a day off to fit my H50). Will this do the trick? Will I need anything else?
 
I doubt it's temperature. DDR3 tends to run even cooler than DDR2, and DDR2 rarely required extra cooling.
 
It's probably the BIOS options I'm changing then. I'll have a look at it when I get down to overclocking my CPU, I know a fair bit more now than I did then so I'll see how it goes. The only concern I had was the X58M lists supported RAM only up to 1333MHz, but the OcUK guys assured me I'd get the full whack out of the Viper, so I'll see how it goes. To be honest, half of the drive to buy new kit at the moment comes from this being my first self-build - I've always had custom builds, but ordered through retailers, so I'm in a bit of a customising frenzy at the moment.
 
mosfets are basicly the power regulaters to your mobo bits and pieces, what hairydave is talking about is as there is no cooling on them, you would want to be carefull how hard u push the voltages.
 
Out of interest, what bits are the MOSFETs here?

Anyone know what sort of voltages I should avoid?
 
See the things with R50 on them, thats mosfets, most motherboards that have those heatpipe things on, are cooling them and those silver things (capacitors).

Well you will be safe with most voltages, but for example if u try following a guide check to see if they mobo in that quide has a heatpiple cooler around the cpu socket, and then stay under the top end volts from that.

Its hard to give a definative answer really. I can't see you having to many problems, its just that mobo's with cooling in those area's tend to overclock abit better is all.

If you are abit worried, then something like the antec spot cool fan is very usefull, google for it and u will see what i mean.
 
Untrue. The ones with R50 on are capacitors as far as I know. Certainly they're not cooled on any board I've seen. Look slightly further up, the 18 flat objects in triples are mosfets. They're probably very hot to the touch when the system crashes. I think they're considered 'ok' up to 90 degrees or so but much lower would be better. Mosfets cope with the majority of the voltage regulation to the cpu, dropping down from 12V to whatever the processor needs. They also have to deal with stresses related to load line calibration, so turning this off may help the diagnosis.

This is probably your limit at the moment, especially if you're using a tower heatsink they'll be seeing no airflow at all. However ram temperatures can be an issue, either mosfets or ram running too hot is limiting me at the moment, my head tells me it's the mosfets but my gut says it's the ram. Thankfully the dominator I'm using can be water cooled, so it won't be too bad if this is the case.
 
The parts with R50 on them are chokes, the MOSFET's are the small black chips behind the chokes.

By the looks of it, you should be able to fit an aftermarket heatsink onto the MOSFET's of this mobo, however, I'm unsure which heatsink you could use.

Thermalright make some nice chunky MOSFET heatsinks, maybe these would fit this particular board.
 
Watercooling's a bit pricey for my range at the moment, I'd probably step up the board before I did anything that drastic. I've got a corsair H50 so there'll be zero airflow from the CPU cooler to push the temps down, I guess my only real choice is to hope the airflow's good enough to make a difference.

3 stock case fans, 1 that came with the H50 and an apache that I picked up on the TWO last week - the Megahalim/H50 comparison guy got better temps mounting the rad on the exhaust, so I was thinking a bottom, front & side (top rear on the left of the CM690 dominator, aiming at the MOSFETs) intake and apache push/corsair pull over the exhaust. Suggestions to improve the setup? I could stretch to an extra fan this month, if need be.
