RAM temps

[stevorob]

Hey guys, though someone could help me out with a quick question.

I've got a set of G Skill ddr2-800 RAM, and was wondering if 2.2v would be a safe voltage to run them at. Right now, they seem stable running 4-4-4-12 @434mhz at 2.2v on a quick 30-35 minute memtest86 run Before, I couldn't get 4-4-4-12 at all with any voltage under 2.2. G Skill's site has them recommended at 1.9-2.0v

I opened up my case, and took an infared thermometer to the heat spreaders, and they were reading between 40-41C. During memtest, my cpu was reading around 50.

Just for reference, it's this set right here. http://www.newegg.com/Product/Product.asp?Item=N82E16820231084

And the G-skill model Number is F2-6400PHU2-2GBNR.

Do they feel hot to your touch? Also, maybe you can have a side panel fan blowing on it, or use a rubber band (Lol, it works) and tie an 80mm fan to the RAM slots. This actually works and many do it.

Well, my infared thermometer is pretty accurate, and I was zapping the heat spreaders and they were coming out 40-41C. They're not "hot" to the touch, but they are a little warm. I'm just wondering if 2.2v is too much juice for them, and if 40ish temps are too high for RAM.

Lol on the fan idea... I might try that... Or I'll just cut my case and mount 1 blowing onto the RAM.

A lot of people actually do that, using rubber bands to tie 80mm fans, and it works fine too. Luckily, I was able to move my window so the the 80mm fan was directly over my RAM. It's @ 3.4v right now, but it's DDR, not DDR2, so we can't really compare.

Wow, 3.4v

I should be fine I guess at 2.2. I'm happy that I got the timings down... It would BSoD after a minute or so in windows at anything under 2.2v

I had stability issues at 2.6ghz on my proccy... I think it was the RAM, so I dropped back to 2.55 and have my ram running at 425mhz again at 4-4-4-12.

I've tried to keep stability at 2.6, but my board just can't handle the high FSB... I've turned up the voltages on the HTT and chipset, but it still can't handle it. Turned the RAM divider to ddr2-667 to see if it was acutally the RAM limiting the high OC on my chip, but it would still crash around 240ish FSB.

I've got the HTT at 4x right now, cpu voltage at 1.375, mem at 2.2, and chipset at 1.4 I believe. I'm happy until I get the urge again

If I were you, I would read some reviews of your G Skill memory, and see what speeds/voltages they achieved. That's what I did with my GeIL before I overclocked it one bit.

Oh ya 40'C is totally normal for RAMs with heatspreaders, they don't really do much lol

 

[Azn Tr14dZ]

Well, they do. The heat is spread around evenly to the RAM modules, therefore "Heatspreaders", so that not one area has all of the heat and the others don't. It's from what I've heard at least...

Turned my v down to 2.1. Stable. No BSoD.

I think what was happening is that my HTT was still at 5x, leaving me with like an 1100ish FSB. Since I turned the HTT down to 4x, I'm back under 1000... I guess that made my RAM stable at 4-4-4-12.

Yeah, when you OC ram and stuff on AMD chips, you have to make sure you do not go over 1000 as that will cause problems with the onboard memory controller.

41c is a bit on the warm side, nothing too serious. a silent fan blowing directly over them will easily sort them out. its the volts you want to be a little concerned with, ddr2 is quite sensative and without knowing what ICs are on the modules, a silent fan is the safe and sensible optionn.
