How fast can I run 4.0 ns DDR SGRAM? (no heatsinks)
The card (GF2 Ti.. I know I know but it cost me a grand total of $40) runs default at 200DDR/400SDR, and I've bumped it up to 220DDR/440SDR without incident.
Anybody going to support my volition to hit 250/500? :D

4ns means 4 billionths of a second is the time it takes to respond.
Let's do some quick math: 1 billion / 4 = 250 million of those 4ns cycles, or 250MHz.
Concidering that:
You can push that RAM to 250MHz DDR :)
But remember, ANY higher than that and the chips WILL fail to respond in time. The result will be unreliable system operation and therefore, a crash. But, you can always reset the values and your system will work correctly with NO problems...
BTW: How does one boost the RAM's clock speed? I'm stuck with PC100 type SDRAM DIMMs...
Is it acutally that simple to do the conversion? I mean we learned the frequency/period stuff first thing in Physics last semester...
I should try it in the winter :) Right now its a tad warm and without RAMsinks I'm not going to try...
As for your SDRAM, you can probably go into the motherboard BIOS and tweak some settings.
Will do... :)
No, Warmaster, since it's DDR, that would be an effective speed of 500Mhz actually...
Siyan just make sure it's cooled good and you can go even higher :)
he said 250 DDRQuote:

and we dont need cooling up here in canada! :mad:
Actually it's 250 million bytes(times 4 for 32-bits) / sec transfer rate. Since there are 2 channels per DIMM, each channel does the 250MHz. So that's where you get the 500MHz from... Like Siyan said in his first post, 250 DDR / 500 SDR. I am still correct, and you are as well :) Just remember that 250/500 is the limit for that RAM.
I couldn't boost my RAM speed. My BIOS is stupid... But it knows exactly what type of DIMM is in each slot, which I thought was cool. I did a search on my motherboard (AOpen V66XA AGP M/B w/ Intergrated ATI RAGE 3D & Crystal sound). It's mean't for Pentium II, I have a 350MHz PII in there right now, yet someone took an image of the BIOS and looked in the binary strings... It seems as though my board will house a Pentium III @ 500MHz without any problems. This site also said there are some versions of this board that even support Pentium III @ 800MHz. Interesting, but now a good idea - crappy video card.
BTW: Are there special heatsinks designed for RAM? I have never heard of those...
nah just get a whole new system.. :)
Some video cards have heatsinks preinstalled on the RAM in addition to an HSF on the GPU. Mine only has a HSF :(
I'm quite certain you can get little heatsinks that somehow attach to RAM...htey're just a bit hard to find.
Corsair is making a "XMS" series of PC2700 DDR SDRAM chips i think....they're overclocked PC2100s with heatsinks :rolleyes:

They are true PC2700 chips I believe...the XMS3000s and 3200s are overclocked PC2700s.Quote:
