Well, I hate to admit this, but I tend to be kind of a I want to buy it now kind of person, and so (not wanting to wait for one ordered online), I wandered into my local Fry's and bought whatever fan on the shelf looked the best.

Cool, that'll work. I'll go look for an old video card or something and see if I can steal a fan off of it and try that.

That was going to be my second choice if I could not find a fan at Frys -- I have heard of several people doing this, and it worked fine for them.

Your HyperX is the regular one. The spec sheet says it can do 2-3-2-6 at DDR400 on 2.7V, but the default SPD at DDR400 is 2.5-3-3-8 on 2.6V. But it can usually do what the spec says. Also it can usually overclock up to 225 MHz (450DDR) at 2.5-3-3-8 on 2.7V. So it's a better then the value RAM, but definetely it's not in the same league as the high end Samsung TCCD based ram which can do 2-2-2-5 at DDR400 and overclock to at least DDR500.

I have seen the review where the guy fried his chipset at 300HTT. I am running mine at 250fsb and was wondering if the stock heatsink will be adequate for leaving it at this setting. I did take it off and put some AS/5 on it. As of now it is stable and the heatsink is very warm to the touch. Any advice would be appreciated.

another quick addition to this, currently running 9x280 on my 3200+ this board is awesome, i really love it. ill be holdin on to this PC for quite some time. (need a new vid card though, this 6600 vanilla is KILLIN me)

I just started OCin today with my 3000+ and VNF4 Ultra, I can get to 255HTT with my RAM running at 166FSB (so 208 OCed). I want to go higher but my RAM is Corsair Value Select and it cant do amazing FSB speeds. I have it at 2.7v right now. When I tried to bump the setting down to 133FSB and reboot it POSTS showing the CPU speed at 10mhz

My cpu temps are fantastic with a Arctic Cooling Freezer 64 slapped on the CPU so I dont think thats a problem. Im using the 1/17 beta bios. My CPU multi is at 9x and my HTT at 3x. RAM timings 2.5/3/3/8

Any ideas?

 

[gobucks]

does anyone know if corsair Value select is unable to run in 1T, or if it's just a BIOS problem?

 

[Geforce man]

pay no attention to the Mhz it shows, its still running at what you put it at, mine does this occasionally as well, but windows shows as well as cpu-z the correct frequency, also, put to 2.9 volts on that corsair ram, it will be fine. then see what you can get.

many value memory modules don't like low timings even at little added speeds, it's often when ddr400 c2.5-3-3-8 memory can't do even 410. try 3-4-4-8-1T, maybe it can allow you upto 230-240. A64 platform is all about "megahertz ownz", so little slower timings don't change perfomance at all. A little more memvoltage can help as well.
my vnf4 runs 3000+ 24/7 primestable 9*270, 3xHT, 1:1 (Adata DDR566 TCCD @540Mhz). mem could go a bit farther, but 2.9V in bios means 2.78V on my machine. bios 01/17.
i'm unlucky with my CPU, it starts to choke even at ~2,5Ghz.

i've heard some users had issues using full 4 mem modules. One user even fried its mobo (and ram module) at default pc3200 speeds.

Thanks OP! Great information on a good value board. Similar reports on that Foxconn board. If that Foxconn can do the same for under $100, I think I'll have to order it this week.

Btw, forgive 1user1234, he has had a beef with this mobo since it came out.
I think he's had some problems with his $300 mobo and needs to vent to justify his purchase.
Maybe his wont do 2.6...

Looks like Chaintech has already made a revision to our board to include an active heatsink. The xbit article does make me chuckle by seemingly implying that the xbit review had something to do with the changes made to the board =P

To be honest I'm not a fan of active heatsinks. On all 4 boards I've owned and used 18+ hours / day, mobo chipset or videocard chipset fans are the first to go and start rattling like crazy. I have to open up the case every month or so to WD-40 the ball bearings.

 

[GadgetBuilder]

WD40 is really a solvent, it thins any remaining grease or oil in the fan bearing, temporarily relieving the problem. It dries out fairly quickly, especially at elevated temps and generally the problem comes back. WD40 is sort of a deodorized fuel oil, not a lubricant.

Try a synthetic oil and see if it lasts longer on your fan bearings, synthetics generally handle elevated temperatures better than mineral oil; something like Mobil 1 might help.

As a test, spray WD40 on a piece of metal and put oil on a similar piece; set them aside for a few weeks and you will find the WD40 piece has a sticky film which isn't slippery, while the oiled piece is still slippery. The sticky WD40 film may prevent rust but it doesn't reduce friction much

I haven't had good luck lubricating fan bearings regardless of the method; replacement has been the only thing which works for me -- although sometimes it is hard/impossible to get a replacement.
