getting PC3200 speeds

Epox 8rda+
2400+ xp
Twinmos PC3200 512 (1 stick no dualddr...but anyway)

jumper set to 133/166
CPU clock ratio at 133
but my memory is still comes to 266, how can I get it running at pc3200 speeds (333 yeah?)

processor comes at right speed, naturally

Your RAM is rated at DDR-400. In order to get the most out of your RAM you need to raise the FSB and also run the RAM in sync (100%) with the FSB. My bet is in single channel mode you should be able to attain over 200 FSB.

I have the same board/ram setup, and mine runs very stable at 200FSB. Use the suggested settings w/2.77VDIMM.

Err... PC3200 is 400mhz, not 333. Athlon systems dont do well with cpu/memory out of sync.

Addressing the NB heat issue is a better approach than getting ambitious and immediately raising the VIO. Get an active chipset cooler for the NB and a smaller non-active heatsink for the SB. Putting the big stock HS on the SB will just keep the SB warm. And since most of the I/O is through the SB, you dont want it to stay warm.

Yike, thats overkill for sure. And it will be in the way if you intend to use pci cards.........you need something small enough so it doesnt lay on top of the two crystals thats under the SB. (The stock Epox NB heatsink needs a couple of extrusions ground away because of these crystals)

Did you look at my pic?

Wrong, the heat sink will aid heat disipation period, we not talking about a blanket here, a heat sink is more conductive and has more surface area than the SB.

Wrong, that Epox heat sink does not have the ability to release heat quickly, it is incorrect for use without a fan. Besides that fact, it will not fit on the 8RDA's SB because of two crystals adjacent to the SB.

Now, if you grind off a bit of two fin extrusions, it will lay flat on the chip and if you screw down a 40-50mm fan, it will circulate air evenly through the upper finned area without the dead air space around the fan hub dissipating air pressure, and if you attach a shroud 1/3 way down from the fan, you will have something functional.....but then again, because if it's height, you can forget about putting a regular length pci card in 2 adjacent slots.

Hello atomic matter! I got two of those zalmans on my setup they fit fine but as I posted on PCGF the vantec Iceburq kit has a small chipset cooler a bit like the old intel BX cooler which will fit on SB and an active VGA/NB cooler you can get it from from www.overclock.co.uk

If you wann do DDR400 then you want to lower the CPU multiplier to keep a stable CPU and slowly up the FSB to see how high you can get then up the multi to overclock if you want to.

Like most ppl bin sayin, run RAM at same speed as FSB for best performance!
You can run asynchronously if your Bios allows the change, wot MoBo have u got?
Wiv the 8RDA+ in the Bios u can manually set the RAM timings, or simply set it to...is it SPID and it will automatically run the RAM at what it's supposed to!
